GNS3 is a graphical network simulator that allows you to design complex network topologies and to launch simulations on them. To allow complete simulations, GNS3 is strongly linked with:., an IOS emulator which allows users to run IOS binary images from Cisco Systems., a text-based front-end for Dynamips., a PIX emulator. GNS3 is a excellent complementary tool to real labs for administrators of Cisco networks or people wanting to pass their CCNA, CCNP, CCIP or CCIE certifications. It can also be used to experiment features of Cisco IOS or to check configurations that need to be deployed later on real routers. This project is an open source product that may be used on multiple platforms, including Windows, Linux, and MacOS X.
Features overview. Designing high quality complex network topologies. Emulating Cisco routers and PIX firewalls. Simulating simple Ethernet, ATM and Frame Relay switches. Load and save in Dynagen’s INI-like format.

And what is Dynamips? — Dynamips is an emulator program that was written by Christophe Fillot to emulate Cisco routers. Dynamips runs on either Linux, Mac OS X and Windows and can emulate the hardware of the Cisco series routing platforms by directly booting an actual Cisco IOS software image into the emulator.It allows users to build complex network topologies to test the functionality of IOS on an desktop PC, without the need of an actual physical Cisco device (Wikipedia.org).
—- for detail info, go to here: @Tanweer you can search another IOS with Google keyword “intitle:index.of ios parent directory bin”. Aziz said, GNS3 is a great front end for Dynamips. Jeremy Grossmann, Benjamin Marsili, Claire Goudjil and Alexey Eromenko(all french men) are the main brains behind GNS3. I remember how much I struggled using Boson Cisco CCNA/CCNP software and Cisco Packet Tracer software to learn CCNA topics. But Boson and packet tracer are half baked and you cannot run all the Cisco IOS commands in these software. You can run Cisco Router IOS on GNS3 to practice CCNA, CCNP and CCIE routing lessons. Only trouble is GNS3 cannot run Switching part.
You still need to depend Cisco Packet Tracer for CCNA CCNP Switching part and real Cisco Switches for CCIE Switching part. Sad I wish some how we could run Switching also in GNS3 You can download GNS3 from below location (GNU GPL license) You can download files which you require for GNS3 from below links. You may need to register and sign in.
Thank you all.
Hi All, I just want to know may I able to configure switching Lab in GNS3???? I read some where we can configure swtiching lab in GNS3 by selecting slot ( NM-16ESW). But by selecting this option in router we can make router as a switch with 16 ports. But we can't configure our router as a switch. Means We can't apply normal CMD's like Vlan.etc. I had used IOS: c3640-jk9o3s-mz.123-14.T7.extracted c7200-jk9o3s-mz.124-19 SWc3560-advipservicesk9-mz.122-46.SE But Not a single IOS is working as a switch.
So, I want to know by using which IOS I can do L3 setiching LAB.???? I want create LAB for Switching only. No need to add router.so, I can make my switch as router for L3 purpose. Please Give me solution ASAP. Thanks, Rajdeep P. Hi All, I just want to know may I able to configure switching Lab in GNS3????

Hi, You can do switching labs in GNS3, but the technologies for switching are limited. Basic switching si available. If the vlans are not saved after router reload (vtp transparent) then, use vtp file nvram:vlan.dat, else don't use it. Hi All, I just want to know may I able to configure switching Lab in GNS3????

Refer to the following document for additional information: 4-Port FXO Voice/Fax Expansion Module (for the NM-HDA Network Module) The EM-HDA-4FXO is a 4-port FXO expansion module for the NM-HDA network module for Cisco 2600 and Cisco 3600 series routers. Using a combination of ports on the base board and optional expansion modules, the NM-HDA supports up to 12 FXS + 4 FXO ports or 4 FXS + 8 FXO ports. Refer to the following document for additional information: New Software Features in Cisco IOS Release 12.2(2) XT The following new software features are supported by the Cisco 3600 series for Cisco IOS Release 12.2(2) XT: Cisco IOS Telephony Service Version 2.0.
Note Cisco IOS Telephony Service Version 2.0 is not supported on the Cisco 3631. The Cisco IOS Telephony Service, under the IP Telephony services umbrella, provides basic Cisco IP phone call-handling capabilities in a LAN environment on the Cisco routers. This feature enables the Cisco multiservice routers to act as the Cisco IOS Telephony Service for the Cisco IP Phone 7960, Cisco IP Phone 7940, Cisco IP Phone 7910, and Cisco IP Conference Station 7935 and helps download phone software images, configures, and manages the Cisco IP phones in your LAN. The Cisco IOS Telephony Service provides you with a telephony system perfect for a small office with a small number of extensions. Refer to the following document for additional information: Cisco IOS Telephony Service Version 2.0 http://www.cisco.com/univercd/cc/td/doc/product/access/ipph/ipks/ipkey2.htm.
Note If you installed Cisco IOS Telephony Service Version 1.0 using Cisco IOS Release 12.1.5YD or 12.2.2XB, some commands have changed. You need to perform the following steps before you can upgrade your router image to 12.2(2)XT: Step 1 Download the Cisco IOS 12.2(2)XT image to the Cisco IOS Telephony Service by entering the copy tftp flash command at the enabled prompt. Follow the instructions to download the image from the tftp server. Step 2 Configure the Cisco IOS Telephony Service to boot from this new image by entering the following at the enabled prompt. Step 4 Save the configuration by entering write memory at the enabled prompt. Examples of computer algorithms.
Step 5 Upload the running configuration on the Cisco IOS Telephony Service to a tftp server by entering the copy running-config tftp command at the enabled prompt and following the instructions. Step 6 Edit the running configuration file on the tftp server by using a text editor to change the word 'keyswitch' to 'telephony-service.' Step 7 Download the edited running configuration file to the Cisco IOS Telephony Service by entering copy tftp startup-config at the enabled prompt and following the instructions. Step 8 Reload the Cisco IOS Telephony Service by entering reload at the enabled prompt. Enter no if you are prompted to save the configuration. If the configuration register is not set to x2 or x2102, but is set to 0x0 instead, you need to boot the router from ROMMON by performing the following steps: Step 1 Upload the running configuration on the Cisco IOS Telephony Service to a tftp server by entering copy running-config tftp at the enabled prompt and following the instructions.
Step 2 Edit the running configuration file on the tftp server by using a text editor to change the word 'keyswitch' to 'telephony-service.' Step 3 Download the edited running configuration file to the Cisco IOS Telephony Service by entering copy tftp startup-config at the enabled prompt and following the instructions. Step 4 Download the Cisco IOS 12.2(2)XT image to the Cisco IOS Telephony Service by entering the copy tftp flash:/slot0 command at the enabled prompt. Follow the instructions to download the image from the tftp server. Step 5 Reload the Cisco IOS Telephony Service by entering reload at the enabled prompt. Enter no if you are prompted to save the configuration. Step 6 Boot the Cisco IOS Telephony Service by entering the boot flash:/slot0: image-name command at ROMMON prompt.
Survivable Remote Site Telephony Version 2.0 The Survivable Remote Site (SRS) Telephony feature, under the IP Telephony services umbrella, provides the Cisco CallManager with fallback support for the Cisco IP phones attached to the Cisco router on your local Ethernet. The SRS Telephony feature enables the routers to provide call handling support for the Cisco IP phones when the Cisco IP phones lose connection to the remote primary, secondary, or tertiary Cisco CallManager or when the WAN connection is down. Cisco CallManager 3.0 supports Cisco IP phones at remote sites attached to Cisco branch office multiservice routers across the WAN. Prior to the SRS Telephony feature, when the WAN connection between the remote branch office router and the Cisco CallManager failed or connectivity with the Cisco CallManager was lost for some reason, the Cisco IP phones at the branch office became unusable for the duration of the failure. The SRS Telephony feature overcomes this problem and enables the basic features of the Cisco IP phones by providing call-handling support on the branch office router for its attached Cisco IP phones.
The system automatically detects the failure and uses the Simple Network Auto Provisioning (SNAP) technology to autoconfigure the branch office router to provide call processing for the local Cisco IP phones. When the WAN link or connection to the primary Cisco CallManager is restored, call-handling capabilities for the Cisco IP phones switch back to the primary Cisco CallManager. During a failure when SRS Telephony feature is enabled, the Cisco IP phone displays a message to inform you that the Cisco IP phones are in the Cisco CallManager fallback mode and are able to perform limited functions.
Refer to the following document for additional information: MIBs Current MIBs To obtain lists of supported MIBs by platform and Cisco IOS release, and to download MIB modules, go to the Cisco MIB website on Cisco.com at Deprecated and Replacement MIBs Old Cisco MIBs will be replaced in a future release. Currently, OLD-CISCO-. MIBs are being converted into more scalable MIBs without affecting existing Cisco IOS products or network management system (NMS) applications. You can update from deprecated MIBs to the replacement MIBs as shown in. Note If you have an account with Cisco.com, you can use Bug Navigator II to find caveats of any severity for any release.

Another option is to go to the following URL: Open Caveats—Cisco IOS Release12.2(2) XT3 This section documents possible unexpected behavior by Cisco IOS Release 12.2(2) XT3 and describes only severity 1 and 2 caveats and select severity 3 caveats. CSCdx04374 If CLNS is configured on the SVI interface (Vlan), the SNPA/MAC is not learned correctly by the router in which the SVI is present. This results in the router sending packets to a non-existent destination MAC address.
There is no workaround. CSCdw46537 Symptom: SPAN doesn't work after moving one port from multi span src ports.
3640 Ios Download
Disabling a source interface from a monitor session results in disabling the entire monitor session, not just the specified port. Workaround: If a particular source port is required to be removed form a SPAN session, stop the entire SPAN session and re-configure with only the required source ports. CSCdw29549 Symptom: Port security failed when configuring secure MAC addresses on an irrelevant port.
When Port Security is configured on two interfaces P1 & P2, and secure MAC addresses M1 & M2are configured on interfaces P1 & P2 respectively, P1 should only allow packets with source MAC address M1 and P2 should only allow M2. But if a packet with secure MAC address M1 ingresses port P1, then the switch treats it like a station movement and allows the packet to be switched. Workaround: Cisco Systems recommends that when station movement takes place, the MAC addresses associated with the port should be cleared in the switch's tables before moving them to another port.
CSCdw14813 Symptom: The command show mac count shows the wrong number of MAC addresses when compared to the count of addresses shown by the show mac command. There is no workaround. CSCdw20431 Symptom: Traceback is seen on configuring the duplex and speed. There is no workaround. Resolved Caveats—Cisco IOS Release12.2(2) XT3 This section documents possible unexpected behavior by Cisco IOS Release 12.2(2) XT3 and describes only severity 1 and 2 caveats and select severity 3 caveats. CSCdv24152 Symptom: A Cisco router that is running Cisco IOS Release 12.0(17)S and later 12.0 S releases may reset if Frame Relay has been incorrectly configured.
If you apply the same data link control (DLC) value on an interface and on its subinterface twice in a row, the router may reset. There is no workaround. CSCdw14262 Symptom: Cisco Voice over IP (VoIP) gateways that are running a Cisco IOS Release 12.2(1a) IP plus image may experience a high central processing unit (CPU) memory utilization condition at the CCH323CT process. There is no workaround.
CSCin02687 Symptom: When using the Cisco 7200 series router as a Survivable Remote Site Telephony (SRST) and IOS telephony service router and making more than 30 three-party conference calls, the router crashes. The tracebacks point to the fast-ethernet interface that is being used to connect the router to the IP phones or rather the IP phone simulator. Workaround: Restrict the number of three-party conference calls.
CSCdv62649 Symptom: The command ip tacacs source-interface does not work properly. Workaround: If configured to use loopback interface for tacacs packets, the router may still use the interface address. CSCdw08182 Symptom: The VWIC installed in NM-1FE2W appears in show diag response but not in the configuration.
The router is recognizing that it has a VWIC-1MFT-T1 in a NM-1FE2W in the show diag. The problem is that the T1 controller doesn't appear in the configuration. The FastEthernet is present. There is no work-around. CSCdw26331 Symptom: A call to a busy FXS port produces an incorrect release cause code. Calls may receive a 'no route to destination' message and an incorrect clearing cause code (instead of a user busy cause code) when calls are placed to a Foreign Exchange Station (FXS) on a busy interface.
Depending on the equipment that is used, the caller may receive a 'number unobtainable' message or fast busy tones instead of a busy tone when this condition occurs. Workaround: Add a huntstop on the dial peer that is assigned to the FXS interface. CSCdw38767 Symptom: Some ports on the NM-16ESW / NMD-36-ESW may not be assigned MAC addresses properly. Conditions: This occurs when the last digit of the base MAC address burnt in the NM cookie is in the range 0xF0- 0xFF for NM-16ESW and range 0xDA-0xFF for NMD-36-ESW. Workaround: None. CSCdw46803 Symptom: After a Cisco 1751 router that is running Cisco IOS Release 12.2(2)XT and that has a BRI network termination/traffic engineering (NT/TE) is reloaded, Layers 1 and 2 may become deactivated. Cod4 cd key. Workaround: Enter the shutdown interface configuration command followed by the no shutdown interface configuration command on the BRI interface.
CSCdw51152 Symptom: PCI Fatal Error on DMA CH1 When access to Flash/NVRAM occurs as a result of write memory or show run commands, and the CPU utilization is high due to heavy packet traffic, this error message can sometimes occur. This is due to the PCI device timing out on the PCI bus waiting for DMA access to memory. Workaround:. CSCdu53333 Symptom: A Cisco router that is running Cisco IOS Release 12.2(1) or 12.2(0.5g) may experience digital signal processor (DSP) reloads or fail to respond after the following DSP Timeout error messages are displayed:%VTSP-3-DSPTIMEOUT: DSP timeout on event 6: DSP ID=0x1: DSP error stats, chnl info(5, 13, 0)%VTSP-3-MSGSNDFAIL: channel:5/0:15 (54516) DSP ID:0x1 Message ID:0x47 The problem is intermittant, and DSPs may hang indefinitely as rarely as only once every few weeks. The problem is likely to appear when T.38 fax mode is used and is likely to appear when 'codec complexity medium' is configured for the voice card and there is frequent switching between the fax and voice modes.
Workaround: This DSP firmware defect is fixed in DSP Release 3.6.15 / VCWare Release 9.19 and DSP Release 3.4.49 / VCWare Release 7.38, as well as newer versions of these firmware releases. CSCdw54986 Symptom: A router with primary-ni switchtype will not be able to interoperate with switches that sends CLID/CLIP/CLIR information in FACILITY messages. The router does not accept the FACILITY and disconnects the call.
Workaround: None. CSCdw57198 Symptom: SRST router with FXO ports typically has a connection plar (opx) to route an incoming call on the port to an extension in the router. With this problem, the incoming call cannot be transferred. There is no workaround. CSCdw62829 Symptom: The High-Density Analog Voice/Fax Network Modules (NM-HDA) for the Cisco 2600 series and Cisco 3600 series routers support Local Voice Busyout (LVBO) features. The busyout monitor command can be configured under NM-HDA voice-ports to permit busyout monitoring of local interfaces or remote IP interfaces via Service Assurance Agent (SAA) probes.
These features can be configured and can be saved to Non-Volatile RAM (NVRAM) successfully, but on a router reload, the boot-time parser rejects the busyout monitor commands. Any busyout monitor command configured under a voice-port on a NM-HDA will disappear from the running-configuration if the router is rebooted. This problem does not occur on VIC-2E/M, VIC-2FXS, and VIC-2FXO voice-ports housed on the NM-1V and NM-2V products. Workaround: Issue a copy startup-config running-config to re-assert the missing commands.
CSCdw70410 Symptom: A Cisco router may reload after a high-density analog voice or fax network module (NM-HDA) that is installed in a slot is replaced by another NM-HDA that has a different hardware configuration. Schiller weltreise rar. Workaround: Use a replacement card that is the same as the original card. This condition will not occur if a card that is the same as the original is used or if a differently configured card is placed in a different slot.
CSCdw71436 Symptom: Under rare circumstances, a Cisco router may reload because of a segmentation violation (SegV) when fax calls are present. There is no workaround. CSCdw73302 Symptom: When using a TCL IVR 2.0 application on a Cisco voice gateway for 2-stage calls, the configured translation rule may be applied for each received digit, instead of only for the initial digit. Workaround: None. CSCdw73507 Symptom: Ringback is not available for calls coming in from a PSTN.
IP phones do not ringback on the network side. When a call comes in from a PSTN, the call should tell the PSTN end so that it can generate ringback on behalf of the IP phones by sending progress ind as 3. Workaround: None.
CSCdw75065 Symptom: Alignment traceback when transfer and conference call. Tracebacks are observed during conference and at times, during regular calls. The tracebacks are on misaligned accesses to memory. Workaround: They are subsequently corrected by the hardware but prints to console are annoying and can be viewed as serious potential issues. CSCdw82677 Symptom: Bad voice-quality during conference call.
This happens when a Survivable Remote Site Telephony (SRST) ITS GW with loop-back-dns is used in conferencing with a remote GW and where a mis-match of codec types results if the GWs do not have the same codec type configured. Conferencing a-law and u-law mixes doesn't work as some legs in ITS end up with a-law and some with u-law which gives bad voice quality. Workaround: This fix is only applicable for a network that has a mixture of A-law and U-law codecs configured in the network. Configure all gateways in the network to use same codec type of either A-law or U-law. CSCdw84594 Symptom: Show diag for Cisco 2600 series routers gives wrong values for NMs which uses TLVIDPROM.
This problem is only on Cisco 2600 series platform Conditions: While issuing sh diag command, HDA uses TLVIDPROM. The hardware version, revision information, and other conditions are displayed wrongly. Workaround: None. CSCdw85359 Symptom: Caller ID is discarded when an incoming PSTN call through FXO-M1/FXS-M1 is transferred to another number. The Caller-ID displayed after the transfer is 'From Private.' Workaround: None:. CSCdx01445 Symptom: The port does not go on-hook when a supervisory disconnect tone is sent from the PSTN.
When call comes in through FXO port to IP Phone, the IP Phone goes into Alerting state. If the caller hangs up at this point, the PSTN sends a supervisory disconnect tone to the FXO where no action is taken which results in not freeing up the port immediately. Workaround: None. CSCuk31298 Symptom: The IP phone locks during a call to a call forward busy number. This condition occurs in a setup whereby the call forward busy feature is configured using the Cisco IOS Telephony Service (ITS) on an IP phone (phone A) to a second IP phone (phone B).
When a call is made from phone A to another phone (phone C), the call can be answered normally. When a second call is placed from another phone to phone A via a loopback-directory number (loopback-dn), the call is forwarded to phone B. As this call is received, the original call is incorrectly cleared by the node on phone C while the call is still shown as 'up' on phone A. When this condition occurs, phone A is no longer able to place or receive calls and has to be powered down to be restored to working condition. Workaround: This condition affects only the first IP phone in the internal control table on the router. The first IP phone is typically indicated as 'ephone 1' when the show ephone EXEC command is issued. To prevent this condition from occurring when the router is operating in the ITS mode, add a dummy phone entry as the first IP phone or 'ephone 1' in the internal control table on the router to prevent an active phone from being listed as the first IP phone in the internal control table of the router.
Reload the router to ensure that the dummy phone occupies the first position in the control table. There is currently no workaround to this condition if the router is operating in the Survivable Remote Site Telephony (SRST) mode (call manager fall back). CSCuk31300 Symptom: Ringing presented to caller before state of called number is known.
When using loopback-dns for outgoing calls, the router presents a ringing tone to the IP phone caller as soon as the call has been routed and before the state of the called number is known. If the called number is busy, this can result in a ringing and then busy tone being played to the caller. This does not happen if loopback-dns are not used, or if they are used for incoming calls.
Do not use loopback-dns for outgoing calls. CSCuk31512 Symptom: On a miss dialed call transfer, a new call shows previously dialed digits. When a Keyswitch IP phone user receives an incoming call, and they then attempt to transfer that call, but while dialling they realize they are dialling a wrong number, the transferrer has two options. If they incorrectly select 'New Call', the phone displays the previous dialed digits. If the caller then dials more digits, these appear after the previous digits.
The phone however only dials the digits presented after the 'New Call' button was pressed, and the call is successful. None. CSCuk31658 Symptom: On three-way calls setup by a Survivable Remote Site Telephony / Keyswitch IP phone, if the second call leg to be setup clears their call, the speech path from the IP phone where the conference was setup to the other phone is lost. The problem is observed only when the second call clears, and only if another IP phone is used in addition to the IP phone which set the conference up. Voice path is re-established if the phone that initiated the conference temporarily places the remaining caller on-hold and then immediately resumes the call. Workaround: None. CSCdw62185 This release integrates the DSPware 3.6.15 release.
Upgrading to the DSPware 3.6.15 release to fix (dsp timeout) remedies the voice quality problem in this caveat.

CSCdv28001 The Cisco 3640 and Cisco 3620 routers return the wrong power supply type when using with the ciscoEnvMonSupplySource snmp query. CSCdv48261 The IOS Firewall Feature set, also known as Cisco Secure Integrated Software, also known as Context Based Access Control (CBAC), and introduced in IOS version 11.2P, has a vulnerability that permits traffic normally expected to be denied by the dynamic access control lists. This vulnerability is documented as Cisco Bug ID CSCdv48261.
No other Cisco product is vulnerable. There is no workaround. This advisory is available at. CSCdv60987 A Cisco router that is running Cisco IOS Release 12.2(1) or a later release may reload when the show flash all EXEC command is entered. Since Cisco IOS Release 12.2(2), the show flash all EXEC command has become part of the show tech EXEC command. This condition is noticeable only on low end systems that support multiple banksizes for internal flash. Workaround: Replace multiple banksize flash with uniform banksize flash.
CSCdv65985 Traceback seen on configuring ISIS, IGRP and RIP. CSCdv76445 Problem: The 3660 configured as a voice gateway will not register to it's gatekeeper after a reload. This can be an intermittent problem, and may not occur on all 3660's. Symptom: If you do a debug ras on the gateway there are no ras messages being sent to the gatekeeper. Workaround: If you do a shut, no shut on the fastethernet interface, the gateway will register to the gatekeeper. CSCdv90919 Problem is occurring when the customer is attempting to receive dial-tone on ISDN trunks. The method that the customer uses to obtain this dial-tone is to configure the ISDN trunks for overlap-receiving, and send in a setup message with no called party number.
The connected PBX then allows the calling party to hear this dial-tone, but continues to collect digits, which will be sent over the ISDN link as INFO messages. In this case, if the router has an incoming dial-peer that has an exact match to the calling party number, a PI value is not returned in the SETUPACK message.
This causes the dial-tone from the router to not be heard. There is no workaround.
CSCdv91454 Can not do inter-vlan ping after the 16 Port Ethernet Switch Module is OIRed (online removed and inserted). CSCdw16395 When a loopback DN is configured using wildcard '.' Characters in the number field under ephone-dn, the caller id for calls that are transferred via the loopback dn (such that the outbound transfer-to call comes from the side of the loopback-DN pair that has wildcards in it's number field) then the caller-id at the transfer-to phone shows 'Private' instead of showing the caller-id of the transferee (original caller). Workaround: do not put '.' Wildcard characters in the (primary) number field of the loopback-dn, instead put this in the secondary number field. For example replace number 40.
With number 4000 secondary 40. Under ephone-dn for loopback DN configurations. CSCdw19173 On MGCP 0.1 voaal2 calls, the Cisco 3660 stops working with 'Memory allocation failed' message There is no workaround for this problem. CSCdw21999 Symptom: The Cisco 3600 sh diag displays wrong cookie values for HDA EM cards. Conditions: sh diag Workaround: None Open Caveats—Cisco IOS Release 12.2(2) XT This section documents possible unexpected behavior by Cisco IOS Release 12.2(2) XT and describes only severity 1 and 2 caveats and select severity 3 caveats. CSCdw04503 Call-forward commands not entered for E164 dial-peers. When dialplan pattern is configured for the local IP Phones, the existing call-forward commands under ephone-dn are not entered under the E.164 dial-peers created by the dialplan pattern command.
This can cause a call not getting forwarded if you dial the entire E164 number. This problem happens only if you add or edit the existing dialplan pattern with call-forward commands already in place.
One way to avoid this problem is to configure the right dialplan pattern before configuring the call-forward commands. Additionally, if you modify the dialplan pattern commands, configure the call forward commands again under ephone-dn. This creates the call-forward commands under the E164 dial-peers created.
CSCdv78130 Inconsistent music on hold (MOH) during conference. Music on hold works inconsistently in certain conditions. A calls B and conferences to C. B puts the conference on hold.
Both A and C hear the MOH. B resumes the call and after a while puts the conference on hold again. Now only A (initiator) hears the MOH.
There is no workaround. CSCdv72916 Remote branch Analog Phone to IP Phone call disconnected during CM reconnect. Calls from Analog Phone to IP Phone during call-manager-fallback mode may get disconnected when the WAN link to CM comes back up. If a call is made in 'normal mode' and the WAN link fails, the call stays up even though the WAN link failed. If the WAN link comes back up during the call and the call is between two IP phones or two analog phones, the call is not dropped.

The link has 2 videos, video1 is about topology and video 2 about configuration. In video 2 the mentor managed to run the SWITCHPORT command on an interface. I followed his topology, but when I go to an interface and run the SWICTHPORT command, it's not recognized. Example #Config terminal #interface f0/0 #Switchport mode access or even when you type the question mark? At the interface there is no SWITCHPORT command there. Please try to watch video 2, and if you have GNS3 and an IOS image 3640, try to simulate the switch the way the mentor on the video did and you'll find out.
Cisco IOS images for Dynamips GNS3 offers multiple ways to emulate IOS. For older images, we use and maintain Dynamips; an emulator dedicated to emulate some Cisco hardware. Dynamips can run unmodified IOS images. In the new GNS3 1.4, there is a way to run a second category of switches and routers. These are classified as Routing and Switching virtual machines (or R+Svms) for short. What are the differences? Here are the major differences:.
IOS images are usually run in Dynamips however R+Svms are housed in a virtual machine. IOS images are lower in cpu and memory so you can fit more of them in one topology. R+Svms are all vendor Routing and Switching images that are larger in size but can be imported into GNS3 for real world network emulation.
Only the c7200 series get newer IOS 15 images. All other platforms are now end-of-life and only support IOS 12.4. Please note that the IOSv appliance is based on IOS 15 and there are IOU (IOS on UNIX) images with IOS 15. You will find the technology train images to contain the newest features but it may also contain the most bugs.
We recommend Mainline over Technology train if you are interested on stability without the need of new features.Please see for more information. The minimum RAM is the amount of memory needed for IOS to work at maximum capacity with most feature configured and activated. From experience you can usually use a bit less RAM just fine.
We really recommend using c3640, c3660, c3725, c3745 and c7200 IOS images listed below, they have proven to be the most stable in GNS3 provided you use the right amount of RAM and Idle-PC value. This settings will help Dynamips to consume less CPU.
It’s specific to each different IOS image. 1700s have 1 FastEthernet fixed port (C1700-MB-1ETH) on its motherboard, 2 subslots for WICs (maximum of 2 Ethernet ports or 4 serial ports), and no Network Module slots.
