LACP configuration

[pankit336@gmail.com]

Hi team,

i have one confusion on my mind,

i have configured lacp on a 3570 switch and i have allowed one native vlan on a trunk port in a port group of a lacp.

now my question is i have multiple vlan in the network is all vlan pass though the trunk port aur only native vlan will pass.

thanks in advance.

Hi there,

If a switchport is operating in mode trunk, if you have not explicitly listed the VLAN IDs which you want enabled, then all VLANs will be tagged.

You can confirm this yourself with the command:

sh int <port-channel-x> switchport

...near the bottom of the output will be the line 'Trunking VLANs enabled: xxxx'

cheers,

Seb.
