So I have a new FS switch, running a 40Gb port split to 4x 10Gb connected to the 4x 10Gb SFP+ ports on the expansion module.
On the SDX - all 4 ports are aggregated.
On the FS Switch - all 4 ports are aggregated, set to trunk.
Additionally the load balance setting for aggregate ports on the FS is set to balance by Source and Destination IP. Open LACP is also turn on for this AG port.
Issue:
With Open LACP on → FS syslog says: Interface TenGigabitEthernet 1/0/27 suspended: LACP currently not enabled on the remote port. Update: with this open selected I noticed the AG port was forced to “copper” medium type instead of “fiber” and I read that LACP requires this to match, so waiting on
With Open LACP off → w/ Single port used things work fine, plug in a second port on the AG and i lose connectivity to the SDX and get drops with pinging the FS switch.
I have the same situation with a 580X 8.4.1 build 5791and the Cisco 9300 switch. Pep support just provided a link to Cisco LACP troubleshooting steps.
Logging shows the switch sent many LACPDUs and received none from the 580X.
There are several other LACP channels in the same switch working fine.
Update: Downgraded to 8.4.0 and reset to factory, setup LACP before anything else and it worked. I tried 8.4.1 a 2nd time and failed again. So I’m staying at 8.4.0. - Fortunately the 8.4.1 config backup restored fine under 8.4.0.
So, LACP is seems dead under 8.4.1.
Hmm 8.4 did nothing for me.
Whats the config for your ethernet ports and your aggregate port on your cisco?
Config:
switchport access vlan 999
switchport mode access
channel-group 31 mode active
Wait so the ports are supposed to be access instead of trunk?
I didn’t try trunk ports. My requirement is just access.
