Minimum Switch Multiple VLANs

[Pete89]

We have a core switch that has 77 VLANs in the VTP domain. We are working to get this number down, but right now I have a few older switches that can only deal with 64 vlans. Also I am looking to put some Express 500 switches in our confernece rooms for a NAC deployment. I am sure that the 500s will only see 64 (or less) vlans. I want these switches to take part in the VTP domain as clients.

Questions:

Since I have a limit of only 64 VLANs on the older and I assume Express 500 series, can I pick and choose which VLANs they will talk on? In other words, since they cant talk on and see all 77 VLANs, can I tell the switches "theses all the vlans you need to deal with"?.

And how does that command look on the trunk?

Thanks a million,

P.

Apologies for delay in getting back.

Are there any other switches between the switch you are on and the 6500 that routes the vlans.

Can you post "sh int trunk" from all switches along the path.

Also from the vlan the pc is in can you ping it's default-gateway on the 6500.

Yes. There is a switch between the 6500 and the switch I am on.

sh int trunk does not work on the switch I am on and the intermediary switch since both are 2924

Yes PCs on all vlans can ping its default-gateways.

Can you provide the list of commands you did on each switch +

"sh int trunk" from 6500 that connects to intermediary switch.

Also try "sh trunk" on 2924 - not sure it will work but worth a try.
