pruning on catos

[schannro]

Hallo!

I have a problem with pruning on an C6009 ( version 7-6-10 ). I would like to exclude one trunk port from pruning.

On a IOS System it is very simple "switchport trunk pruning vlan {add|exept|none|remove}

i hope anybody can help me

For catos it's simple too, just "clear trunk slot/port

vlan # " .

Hi,

set vtp pruning enable

set vtp pruneeligible ...

are the proper commands.

But you can't configure VTP pruning per trunk in CatOS, just per VTP domain or per device.

See http://www.cisco.com/univercd/cc/td/doc/product/lan/cat4000/rel7_6/config/vtp.htm#1020217

for details.

Regards,

Milan

Hi,

I have a trunk port to a non Cisco device ( a Firewall ). the Firewall need all Vlans in the Domain.

What ist the affect, if I enable pruning in the domain?

a - all Vlans are blocking

b - all Vlans are forwarding

Hi,

I beleive it should work.

It's similar to "router on the stick" configuration which works with VTP pruning enabled.
