WS-C5505 to WS-C2924C VLAN trunking.

[DSJONES10]

We have a 5505 running SW 5.2(4) and a 2924 running SW 12.0(5.4)WC(1. We need to run a VLAN trunk between them. Does anyone know if this is possible and what are the "gotchas"?

Thanks.

Hi,

it should be possible using 802.1q trunk.

The limits are: 2924 supports 802.1q only (not ISL) and doesn't provide trunk negotiation.

Configure

interface FastEthernet0/x

switchport trunk encapsulation dot1q

switchport mode trunk

on the 2924

and

set trunk x/y nonegotiate dot1q 1-1005

on the 5505.

You should also care about VTP domains and revision numbers if you are using VTP in your network.

Generally: CatOS 5.2(4) is pretty old and I'd recommend an upgrade.

Regards,

Milan

Also, make sure the 5505 port supports trunking. Use the 'show port capability' command.
