VLANS on GNS3

CiscoCerts

Hi all,

I've been trying all day to get this to work and I would like some help.


I've got three 3660 Routers with the NM-16ESW adapter.
This is the IOS i'm using c3660-js-mz.124-19.bin

I was able to create trunking links between them successfully.

They're all in server mode. I haven't been able to use commands "vtp domain LINE" or "vtp mode client|server|transparent" they also are not sending updates over the trunk links

I've got a couple VLANs created, VLAN 10 and VLAN 20 and they show up in the running-config but when I do a "show vlans" I get No Virtual LANs configured.

I have other routers and was able to create sub interfaces for the seperate vlans f0/0.10 f0/0.20 etc with encap dot1q

Would someone shed some light on this for me please?

And the answer is....

The commands are in a different place than on a real switch! You have to use the "vlan database" command in privledged mode to change the vlan settings


SW1#vlan database
SW1(vlan)#?
VLAN database editing buffer manipulation commands:
abort Exit mode without applying the changes
apply Apply current changes and bump revision number
exit Apply changes, bump revision number, and exit mode
no Negate a command or set its defaults
reset Abandon current changes and reread current database
show Show database information
vlan Add, delete, or modify values associated with a single VLAN
vtp Perform VTP administrative functions.


I'm so happy now I can go practice fully on this subject.
