Regarding a GNS3 with Switch....

Rajdeep Parmar

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

SW_c3560-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 Rajdeep,

For switching practice using GNS3 simulator  there are two options to simulate switches.

1)  Use generic ethernet switch provided by GNS3 features:
- VLANs
- dot1q trunk

2) Use 16 port switch module in 3600 or 3700  series router
- more features than in generic switch
-  not features like PVLAN or MSTP (not in real life either)


Hope to Help !!

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.

R1#sh spanning-tree

VLAN20 is executing the ieee compatible Spanning Tree protocol
  Bridge Identifier has priority 32768, address cc00.1218.0000
  Configured hello time 2, max age 20, forward delay 15
  We are the root of the spanning tree
  Topology change flag set, detected flag set
  Number of topology changes 1 last change occurred 00:00:30 ago
          from FastEthernet1/1
  Times:  hold 1, topology change 35, notification 2
          hello 2, max age 20, forward delay 15
  Timers: hello 1, topology change 5, notification 0, aging 300

Port 42 (FastEthernet1/1) of VLAN20 is forwarding
