LACP ports from B3 vs B5 Enterasys Switch

[Mark_Robinson]

Is there a difference between these two switches when configuring LACP? We replaced a B3 with a B5 switch with identical configuration and the LACP ports appeared to create a loop. The only difference between these two units (besides model) would be the B5 had a newer firmware 06.81.04.0001. Any suggestions would be appreciated.

Thanks Ryan. I believe that will resolve the issue. Also much appreciated for the prompt reply.

Mark,

That is correct. B5 configuration does not have that command enabled for the ports like the B3 has. Setting that command should bring the LAG up. You can also verify if LACP packets are being broadcast every 30 seconds on ports with command "show port lacp port ge.1.46-48 counters" and look at the LACPDU TX and RX values for transmitted and received.

To confirm, lacp ports would require this command such as:
set port lacp port ge.1.46-48 enable"

Is this correct?
