S4128 - port-channel with more than 1 VLAN and VLT
Hi there,
I have this:
...
interface port-channel1
no shutdown
switchport mode trunk
switchport access vlan 1
vlt-port-channel 1
...
and I would like to add VLAN X.
Can I simple add "switchport trunk allowed vlan X" or will this interrupt my connection? I need both.
Thank you!

Hello,
With your current configuration "switchport mode trunk" allows all vlans as tagged vlans. So there is no need to add vlan x.
If you want to specify a specific list of vlans, you can use "switchport trunk allowed vlan 10, 20, 30" , it will remove any vlans that are not in the list and interrupt connection only for them.
