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.

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 raj,
In most of the layer 3 switching all the forwarding are done by the hardware... so in short , packets are all hardware switched.... so i would say switching is platform dependent which means each switch like 3750/4500/6500 has it own way for forwarding packets in hardware...
since this is platform specific, i think it cannot be done on gns3 even though you have the right IOS.
