ctAliasInterface
Module: CTRON-ALIAS-MIB
OID (symbolic): CTRON-ALIAS-MIB::ctAliasInterface
OID (numeric): 1.3.6.1.4.1.52.4.1.3.7.1.1.1.1.3
Node type: OBJECT-TYPE
Type: InterfaceIndex
Access: read-only
Description: The ifIndex of the interface on which this entry was discovered.
The ifIndex is an 'external value' that identifies a physical component associated with the Alias entry. This object can be used to identify the physical location of the interface in the ifTable [RFC2863].
The possibility of ifIndex value re-assignment must be accommodated by a management application whenever the value of sysUpTime is reset to zero.
Since ifIndex values in different 'naming scopes' are not related to one another, the interface to physical component associations are relative to the same logical entity within the agent. For more discussion of naming scopes, see the ENTITY-MIB [RFC2037]
What is ctAliasInterface?
This is the ifIndex value identifying the physical interface on which this alias entry was originally discovered, serving as an external reference into the standard ifTable. An admin can use it to map a learned address alias back to the exact physical port on the device, keeping in mind that ifIndex values can be reassigned whenever sysUpTime resets to zero. For example, if an alias entry shows ctAliasInterface value 7, checking ifDescr for ifIndex 7 tells the admin exactly which physical port learned that address.
