LACP on 2910al using SFP+SR ports
Hi,
i have two 2910al switches with SFP+SR ports I would like to trunk the two switch together using the SFP+ports
these are the command I use on both switches yet the port status do not change to UP
any idea what I need to do to bring these ports up?
if i do a "show tech transceivers" the SFP+SR ports are being initialized.
See all info below
hpswitch1(config)# a1-a2 Trk1 LACP
hpswitch2(config)# a1-a2 Trk1 LACP
hpswitch1(config)# int a1-a2
hpswitch1(eth-A1-A2)# enable
hpswitch2(config)# int a1-a2
hpswitch2(eth-A1-A2)# enable
hpswitch1(config)# show lacp

Re: LACP on 2910al using SFP+SR ports
Hi,
the LACP config seems to be correct
may you ensure if there is config mismatch ( speed , duplex, vlan allowed, ....)
also check the cables.
if the issue still persist remove the lacp config and check the transciver one by one.
for example: connection between both switch using only one link.
try to loop one transciver ( connect TX to RX ) and see if it works.
hope it will be helpful.
