L2 EtherChannel w_different VLANS

Can you build a 2 channel etherchannel or a 2 channel etherchannel dot1Q TRUNK and then put TWO vlans on it ??

Here is what the customer is asking for >> Specifically with the Log Server, though we'd like to have a separate Ethernet cable dedicated to the management VLAN, we can trunk it over the same EtherChannel physical cables.

So - They are asking for VLAN X = data

VLAN Y = mgmt ON THE SAME ECHANNEL bundle. We use Lacp on this type of server to access 6509 bundle. Thx.

If i understand correctly that is exactly what an etherchannel trunk is ie. a number of aggregated links that are seen as one logical link that can pass multiple vlans.

So yes, create the L2 etherchannel, make it a trunk and if you only want to allow just the 2 vlans use the "switchport trunk vlan allowed ..." configuration to restrict the vlans on the trunk.
