Add a VLAN to a channel-group on 62xx switch...
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. :emotion-7:
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----------------------------------------------
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 101,2200,20,30,40 tagged

--And this won't cause any hiccups, or require a switch/stack reload will it? Sorry to ask a silly question, but I hate not having a devel environment where I can test these things :-)
Lastly, in my M6220 config, the line switchport general allowed vlan add 101,2200 tagged is actually in quotations, like:
"switchport general allowed vlan add 101,2200 tagged"
and none of the other config items in that channel group are in quotes. Is there a significance to this? When I configure the M6220, do I need the quotes?

The configuration on the M6220 is below...
interface port-channel 12
description 'LAG12 MGT TRK-->1000sw101010'
switchport mode general
switchport general acceptable-frame-type tagged-only
switchport forbidden vlan add 1
"switchport general allowed vlan add 101,2200 tagged"
exit
In other places in the M6220 config, other types of lines are also surrounded in quotes. The 'switchport' commands, the 'banner' command and the 'snmp-server community xxxxxxxx ro' command, all are surrounded in double-quotes like: " " ". All other lines have no quotes. the output I'm looking at, is the "show run" command, using puTTY.
Lastly, the new VLAN's I'll be putting on this channel-group don't have nearly enough traffic to saturate this channel-group. It's a 4-member channel-group, so thats an aggregate 4GB bandwidth between my 6248 and the M6220.

And to confirm, the command for adding VLANs to an Ethernet interface is the same as adding VLANs to a Channel-Group, correct? -and the interface members of that channel group will all stay members & stay intact?
