Hi Todd

I'm pretty sure that this answers my question. Just to check that I have understood properly, the following configuration will allow me to add the new vlan 1139 to our switches:

enable

configure

vlan database

vlan 1139

exit

configure

interface ethernet 1/g1

switchport trunk allowed vlan add 1139

exit

Repeat for all interfaces!!!!

exit

copy running-config startup-config

Many Thanks

John

Hi Thilo

I have seen range configuration before but haven't used it - so thanks for pointing that out otherwise I would have done all the interfaces separately! I have put my new configuration script below.

I have 2 short follow-on queries to ask to you don't mind?

1) When doing a range configuration, will it leave the current configuration intact on all interfaces unless an item is explicitly removed?

2) I want to configure the ranges 1/g1 to 1/g16 and 2/g1 to 2/g16 - can I do this in one operation? (I have scripted in 2 separate operations below).

Thanks

John

enable

configure

vlan database

vlan 1139

exit

configure

interface ethernet 1/g1-1/g16

switchport trunk allowed vlan add 1139

exit

interface ethernet 2/g1-2/g16

switchport trunk allowed vlan add 1139

exit

exit

copy running-config startup-config

1) It should leave the config intact

2) you have to do this in 2 operations
