Add VLAN to a Port-Channel

[ray_vandervelde]

I want to add vlan 708 to an existing port channel.  I know I have to add it to both ends of the port channel.

This is the existing config.

switchport trunk native vlan 854
switchport trunk allowed vlan 801,803,804,806,807,827,832,842,854,870,872,892
switchport trunk allowed vlan add 896,1810,2700

Should I use "switchport trunk allowed vlan add 708, or do I have to use  switchport trunk allowed vlan add 896,1810,2700,708.  Seems like if I use just the add 708 version the vlans that are already on the add statement will be on the allwoed vlan line?

Thanks

switchport trunk allowed vlan add 708 will do the job.

HTH,

You are correct.  Adding 708  will work.

Thanks Guys.

That is what I thought but I wanted to be sure since it is a production switch and I rarely do these.
