vsiLogicalIfIndex
Module: CISCO-VSIMASTER-MIB
OID (symbolic): CISCO-VSIMASTER-MIB::vsiLogicalIfIndex
OID (numeric): 1.3.6.1.4.1.9.9.162.1.3.1.2
Node type: OBJECT-TYPE
Type: VsiLogicalIfIndex
Access: read-only
Description: A unique value, greater than zero, for each VSI logical interface. Logical interface numbers are selected by the switch to be unique and persistent. The same number is preserved through power failures. This index is not the same as an ifIndex. It is an abstract number provided by the slave, representing a virtual interface, which is an identifier to be used when communicating with the slave about an interface.
What is vsiLogicalIfIndex?
This read-only object is the unique, persistent identifier the switch assigns to each VSI logical interface, distinct from the standard ifIndex, and it remains stable even across power failures. An administrator relies on this stable identifier to track a specific logical interface over time and reboots, since it won't be renumbered the way some other indexes might be. For example, an admin scripting periodic checks of a particular logical interface's cell counters can rely on vsiLogicalIfIndex staying the same after the switch reboots.
