Hi,

I have a cisco 4500 acting as my layer 3 router, hanging off I have a many other switches, all cisco .

I have already three vlans, talking fine, but I have added anoth (vlan 60) and it won't talk.

All switches are set to VTP servers

Config of 4500 is...


ip subnet-zero

Vlan 50 = 172.50.x.x
vlan 60 = 172.60.x.x
vlan 1 = 172.30.x.x

The port with the machine in 172.60.x.x is fa0/23

This switch goes through a 3512 to the 4500, config as below..

ip subnet-zero
cluster enable LINCOLNHOUSE 0
cluster member 3 mac-address 0030.94ed.e5c0
cluster member 4 mac-address 00b0.646b.01c0

If you do a show vlan on the 2924 does vlan 60 show up with the ports assigned to it ? Did you activate vlan 60 in the vlan database ?

Yes, the Vlan shows up with the port assigned to it.

You might be right about activating Vlan 60 in the Database, but I don't know how to do this :-) I inherited the network.

Possibley needs activating on both the 4500 and 2924.

Thanks

One other thing to add, I can ping the 172.60.1.254 address of interface vlan 60 from anywhere on the network other than VLAN 60 assigned devices.

Well unless I missed something you Vlan 1 interface is set to 172.30.2.14. Shouldn't it be 172.60.2.14?

Opps I forgot that you are trunking. I didn't see a default gateway listed.
