Unable to add ports to LAG
Hi, I couldn't find any similar discussion. That's why I am asking. I have succeeded with setting up link aggregation using HP 5800AF, Allied Telesis CentreCom GS908M, Switch Blade x908, CentreC...
Hi Akira,
Please try to configure same VLAN setting on LAG not only the physical port.
Actually the configuration only effect on LAG when physical port added into LAG.
Such as:
configure same VLAN PVID/VLAN member/VLAN Tag For the LAG which port 17/18 will add into.
I see. We will do that.
Thank you.
Best regards,
I hope this helps, it is more of tip to troubleshooting LAG configuration between switches.
For LAG Issues or troubleshooting, here is basic way to validate and test for issues.
1. Add only 1 member port on both switch to the LAG and then check if the LAG status is up. (1 Port member only) You can choose you settings to match (Static, LACP, (Active, Passive --some one should be active and not both be passive), common hash method)
2. If LAG is UP and you can get traffic across, then add second Port member to the LAG and see if the LAG is up. If LAG is not up, you have mis-match or cross cabling which is most common problem we see with LAG configuration. Mis-match means the cable going to the port is not really connected the member LAG port so you have both a LAG port and non LAG port connected between the 2 switches.
To determine mis-match or bad cabling, disable (shutdown) one of port in the LAG and see if LAG is up. Attempt the same on second port if still no change.
