I have an 8 port 10GB module in my BD8810 and I seem to have lost a port. Port 1:2 is a master port of a LAG with port 1:8 to my data center. I have changed out SFP modules and the port will not become active and is constantly flapping filling up my logs. I have tried moving the connection to another port (1:1) just to see if it became active and it did so this points me to a port issue rather than a fiber or SFP issue.
I have tried restarting the port to see if that helps but it didn't. Is there anything I can do short of rebooting the switch (network core)? I can add another port to the LAG and use this port and not utilize port 1:2 but with it being the master port I don't want to do this. Can I add another port to the LAG and then change master?
