How To Configure CISCO Callmanager Manager Express GUI On GNS3

 How To Configure CISCO Callmanager Manager Express GUI On GNS3

I will use a 7200 router. first you need to know how to configure the external flash disk ATA, because the internal flash memory "SIMM" in GNS3 routers is small:

1-Extract both the CME basic and CME GUI archives into a single folder on your computer.
2- Repackage the extracted files (except .tar files) into a new tar file (7-Zip is free and can create tar files in Windows). It is very important not to package other .tar files in this new archive, since tar files need to be individually uploaded and extracted on the router.
3- Use the following command to upload and extract each tar files you need:
archive tar /xtract tftp://xxx.xxx.xxx.xxx/file.tar disk0:/

R1(config)#ip http server
R1(config)#ip http path disk0:/
R1(config)#telephony-service
R1(config-telephony)#web admin system name gawad password cisco
R1(config-telephony)#dn-webedit
R1(config-telephony)#time-webedit

GNS3 Error 205-VM R1: unable to add binding for slot 0/0


بسم الله والحمد لله والصلاة والسلام علي رسول الله وآله وصحبه وإخوانه وسلم

GNS3 Error 205-VM R1: unable to add binding for slot 0/0


This error occurs when you try to connect one of your routers to the real network but you do not find any network cards appears in the network adapters list. for example if you run the Network device list.cmd in the GNS3 installation directory you may encounter the following error message:

This is because you many not have the you do not the privileges on the GNS3 folder in the installation directory for example the c drive (C:\).

So to solve this problem do the following:
 For me "gawad" i will give this user the full privileges on the GNS3 installation folder:


 Then run the script again:

How To Emulate Fiber Optics In GNS3


 بسم الله والحمد لله والصلاة والسلام علي رسول الله وآله وصحبه وإخوانه وسلم

How To Emulate Fiber Optics In GNS3

This post is concerned about how to emulate Fiber Optics on GNS3. But first we need to know some key points.

Synchronous optical network (SONET), a synchronous transmission system defined by ANSI, is an international standard transmission protocol. It adopts optical transmission.
In SDH defined by CCIT (today’s ITU-T), adoption of synchronous multiplexing and flexible mapping allows you to add/drop low-speed tributary signals from SDH signal without large amount of multiplexing/demultiplexing devices. This reduces signal attenuation and device investment.

Packet over SONET/SDH (POS) is a technology popular in WAN and MAN. It can support packet data such as IP packets.
POS maps length-variable packets directly to SONET synchronous payloads and uses the SONET physical layer transmission standard. It offers high-speed, reliable, and point-to-point data connectivity.
The POS interface on your device supports PPP, Frame Relay, and HDLC at the data link layer and IP at the network layer. Its transmission rate can vary with devices. For example, in the sequence of STM-1 (155 Mbps), STM-4c (622 Mbps) and STM-16c/STM-16 (2.5 Gbps), the rate of each level is four times that of the immediate lower level.

Configuration:

Note that the fiber optics interface (POS) is available only on Cisco router 7200 series.



Right click the router and choose configure.


 
































This feature is useful for emulating Fiber Channels and other features related to fiber. the only missed feature is that GNS3 does not support capturing packets of fiber ports using wireshark.
I hope that has been informative to you.

How to Emulate Cisco Router External Falsh Memory "ATA PCMCIA Card" in GNS3


بسم الله والحمد لله والصلاة والسلام علي رسول الله وآله وصحبه وإخوانه وسلم


 How to Emulate Cisco Router External Falsh Memory "ATA PCMCIA Card" in GNS3



1-  Right click the router and choose configure.
2- go to the Memories and disks tab as shown in the figure and configure the size of the flash memory.



3- to see the size of the configured flash memory in the router type "show version" in the console screen as shown:

4- the flash memory by default will be slot0 or slot1 or both. formatting this slot will not be possible "really don't know why"
5- but the GNS3 router will consider the flash memory configured previously disk0 or disk1, so we will format disk0 instead of slot0 as shown in the figure.
6- after formatting, dir the disk0 to see it's contents as shown in the figure.
7- you can now copy files like for example IOS or any other files using TFTP server or any method that is compatible.
