3120x stack - can use LACP ?

[steve switzer]

Hi

Can i use LACP in a stack across different 3120x switches ?

When i last tried it i recieved an error message.

The intention is to bind 4 different ports on 2 different switches

in the same stack - but when going from on to active

on the 3120 I get an error.

Thanks

Steve

Hi Steve,

I was looking in cisco doc but in the datasheet say etherchannel it's supported but don't say anything for LACP.

from the documents, it seems that it supports LACP over switch stack.

>>By using LACP, the switch or switch stack learns  the identity of partners capable of supporting LACP and the capabilities  of each port.
