What is ctVirtualIfType?

This read-only object identifier reports the type of the physical interface underlying a virtual interface. An admin uses it to see what medium the virtual circuit is actually riding on. For example, ctVirtualIfType returning an OID identifying a SONET/ATM interface tells the admin what medium underlies this virtual circuit.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.3.3.7.1.1.3
snmpwalk -v2c -c public <target> CTIF-EXT-MIB::ctVirtualIfType

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.3.3.7.1.1.3.1
snmpget -v2c -c public <target> CTIF-EXT-MIB::ctVirtualIfType.1
