Greetings;
We have a 4-member Channel-group configured between a 6248 switch, and an M6220 blade-switch in the back of an M1000 chassis. I need to add a few VLANs to this 'trunk' so-to-speak, but I don't have a devel environment, so I can't test this command.
In doing some reading, I think it goes something like this... --Can someone who's done this before confirm? i want to make sure that I'm truly adding VLANs to the trunk, and not *replacing* what's there. I have a bad experience where I did this wrong once, on a Cisco switch, and managed to un-trunk the management interface to the switch. This required a mad dash to the server room with a console cable to repair. Can't have that happen again. [:S]
Current------------------------------------------
interface port-channel 12
description 'description goes here'
switchport mode general
switchport general acceptable-frame-type tagged-only
switchport forbidden vlan add 1
switchport general allowed vlan add 101,2200 tagged
I will enter--------------------------------------------
switch70 (config-if)# switchport general allowed vlan add 20,30,40 tagged
Then my config is----------------------------------------------
