SNMP ifIndex MIB Object Values
In an NMS, the IF-MIB generates and assigns an interface index (ifIndex) object value that is a unique
number greater than zero to identify a physical or a logical interface. When the switch reboots or the
switch software is upgraded, the switch uses this same value for the interface. For example, if the switch
assigns a port 2 an ifIndex value of 10003, this value is the same after the switch reboots.
The switch uses one of the values in
Table 30-3
Interface Type
SVI
EtherChannel
Physical (such as Gigabit Ethernet or SFP
on type and port numbers
Null
Loopback and Tunnel
1. SVI = switch virtual interface
2. SFP = small form-factor pluggable
The switch might not use sequential values within a range.
