Will I break the channel bond?

[abillybob]

Hi All

 

So I'm creating a new VLAN called VLAN 210. Currently our fibre links to the other Cabs are bonded using an etherchannel. I know they have to match otherwise you break the bond but my question is am I just able to add the line "switchport trunk allowed vlan 201-210"? It's currently just allowed vlan 201-209. Would this break the bonding and if so is there a best practice way to do this?

 

I normally just keep my trunks set to "All" to it will pass through all vlans no matter what I add but I was told not to do this for security reasons?

 

Thank youuuu!

You will be ok if you add it to the etherchannel

Conf t

int PO

switchport trunk allowed vlan 201-210

 

or this will be better as when you run "switchport trunk allowed vlan 201-210" it knocks off all VLANs for a second or so. The below will not. It will just add VLAN 210 to the allowed VLANS. Don't forget to add it on the switch on the other side of the link.
