You can try the following traps: agentInventoryStackPortTotalErrors .1.3.6.1.4.1.674.10895.5000.2.6132.1.1.13.7.2.1.10 agentInventoryStackPortErrorRate .1.3.6.1.4.1.674.10895.5000.2.6132.1.1.13.7.2.1.9 agentInventoryStackPortDataRate .1.3.6.1.4.1.674.10895.5000.2.6132.1.1.13.7.2.1.8   The categories look the same as the counters list. 
I have 5x 6248 stacked together in a ring ... I can view the Stack Point Counters through the web UI.  I'm using munin to graph system attributes, and it finds all of the regular ethernet ports on each device, but not the stack ports. An example snmpwalk will show, for example: IF-MIB::ifDescr.47 = STRING: Unit: 1 Slot: 0 Port: 47 Gigabit - LevelIF-MIB::ifDescr.48 = STRING: Unit: 1 Slot: 0 Port: 48 Gigabit - LevelIF-MIB::ifDescr.49 = STRING: Unit: 1 Slot: 0 Port: 49 10G - LevelIF-MIB::ifDescr.50 = STRING: Unit: 1 Slot: 0 Port: 50 10G - LevelIF-MIB::ifDescr.51 = STRING: Unit: 1 Slot: 0 Port: 51 10G - LevelIF-MIB::ifDescr.52 = STRING: Unit: 1 Slot: 0 Port: 52 10G - LevelIF-MIB::ifDescr.53 = STRING: Unit: 2 Slot: 0 Port: 1 Gigabit - LevelIF-MIB::ifDescr.54 = STRING: Unit: 2 Slot: 0 Port: 2 Gigabit - Level Those 10G are the optical ports on the front of the switch, but I can not find anything for my friends at the back of the switch.  I'd like to think the ifDescr might come up "Slot: 1" ... any hints on how to find the correct OIDs? Thanks, -danny
