The system image can also be retrieved by performing an SNMP walk on the following OID: MIB Object is
chSysSwModuleTable and the OID is 1.3.6.1.4.1.6027.3.10.1.2.8.
Dell#show interface tengig 1/21
TenGigabitEthernet 1/21 is up, line protocol is up
Hardware is Dell Force10Eth, address is 00:01:e8:0d:b7:4e
Current address is 00:01:e8:0d:b7:4e
Interface index is 72925242

Monitor Port-Channels
To check the status of a Layer 2 port-channel, use f10LinkAggMib (.1.3.6.1.4.1.6027.3.2). In the following
example, Po 1 is a switchport and Po 2 is in Layer 3 mode.
