ctVirtualIfPhysicalInterface

Module: CTIF-EXT-MIB

OID (symbolic): CTIF-EXT-MIB::ctVirtualIfPhysicalInterface

OID (numeric): 1.3.6.1.4.1.52.4.3.3.7.1.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This value displays the physical interface that owns the virtual interface. This is the IfIndex from MIB-II.

What is ctVirtualIfPhysicalInterface?

This read-only integer reports the physical interface, identified by its standard ifIndex, that owns a given virtual interface. An admin uses it to trace a logical circuit back to the physical port carrying it. For example, an admin looks up ctVirtualIfPhysicalInterface for a virtual ATM interface and finds it maps to physical ifIndex 3, the actual OC-3 port carrying that traffic.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.3.3.7.1.1.2
snmpwalk -v2c -c public <target> CTIF-EXT-MIB::ctVirtualIfPhysicalInterface

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.3.3.7.1.1.2.1
snmpget -v2c -c public <target> CTIF-EXT-MIB::ctVirtualIfPhysicalInterface.1
