I have a Catalyst 6513 at the core. We cut-over four IDF's last evening. The typical IDF follows the following model: A 2960X-48FPD-L at the top of stack with one to four 2960X-48FPS-L in each stack. We are using interface GigabitEthernet 1/0/49 & 1/0/50 (Port-channel) to connect to the 6513 over MMF. All IDF's were up last night night. This morning, two IDF's dropped their connections. We were unable to bring the connections up until we moved the Port-channel to 1Gig interfaces one of the 2960X-48FPS-L switches in the stack. I am wondering if there are any known issues with the 1Gig/10Gig shared ports on the 2960X-48FPD-L switches?
Thank you,
Mike
