Service Manual
• the next 5 bits represent the slot number
• the next 1 bit is 0 for a physical interface and 1 for a logical interface
• the next 1 bit is unused
For example, the index 72925242 is 100010110001100000000111010 in binary. The binary interface index for
TeGigabitEthernet 1/21 of a 48-port 10/100/1000Base-T line card with RJ-45 interface. Notice that the
physical/logical bit and the final, unused bit are not given. The interface is physical, so represent this type of
interface by a 0 bit, and the unused bit is always 0. These 2 bits are not given because they are the most
significant bits, and leading zeros are often omitted.
To display the interface number, use the following command.
• Display the interface index number.
EXEC Privilege mode

Example of Deriving the Interface Index Number
To view the system image on Flash Partition A, use the chSysSwInPartitionAImgVers object or, to view the
system image on Flash Partition B, use the chSysSwInPartitionBImgVers object.

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.

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.
