Hello,
We are installing a new VSX stack based on Aruba 8320 VSX stack runnin OS-CX 10.02 We have issue right now where the LAG is not working with HP 5500 partner. First we wer using VSX MCLAG but while it was not working I fallback to one link on LAG on the one switch (non mclag). Here is the case:
We want LAG between the 8320 and 5500 and the link is ethernet 1Gig with tranceivers J8177D on the Aruba side (SPF+ to Eth 1G). Link is up but the lacp is blocked from aruba side.
Here is a snippet from the config:
Aruba 8230:
--------------------------------
interface lag 100
no shutdown
no routing
vlan access 1
lacp mode active
interface 1/1/25
description csw20_1_0_9
no shutdown
lag 100
HP 5500
--------------------------------
interface Bridge-Aggregation120
port link-type trunk
port trunk permit vlan all
link-aggregation mode dynamic
interface GigabitEthernet1/0/9
port link-mode bridge
description testlink_to_new_core2
loopback-detection enable
loopback-detection action semi-block
broadcast-suppression pps 3000
port link-aggregation group 120
This can be seen in the event log for lacpd on Aruba 8320:

I logged a ticket to HPE and not much progress there, they suggested to disable stp on the HP5500 side but it's the same. Negotiation start and then port is blocked.
Any idea why this might happening?
