vtp pruning list for the Catalyst 7606

hello,

i'm trying to build a vtp pruning list for a catalyst 7606 switch - and no matter what i do i always get back an error message saying the list is not wright - the format of the list.

i did read all the docs i could find on the web site.

this is the interface config:

interface FastEthernet3/6

no ip address

duplex full

speed 100

switchport

switchport trunk encapsulation dot1q

switchport mode trunk

no cdp enable

switch(config-if)#switchport trunk pruning vlan except 7,10

Command rejected: Bad VLAN pruning list.

no matter how i define the list - always the same message.

this is my IOS info:

thank you,

ps: the vlan are in there :) - there is nothing wrong with them or with the vtp config

Hi,

Please also include 1002-1005 with vlan 1

switch(config-if)#switchport trunk pruning vlan except 1,7,1002-1005

This will work.

Re: vtp pruning list for the Catalyst 7606

yes - it works - i should have thought of that ...

thank you for your help.

this is what you can see in the sh run after applying the command:

switchport trunk pruning vlan 2-6,8-1001,1006-4094
