ctAliasInterfaceIsActive

Module: CTRON-ALIAS-MIB

OID (symbolic): CTRON-ALIAS-MIB::ctAliasInterfaceIsActive

OID (numeric): 1.3.6.1.4.1.52.4.1.3.7.1.1.8.1.5

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-only

Description: The status of this entry.

A true(1) value indicates the alias is active.

A false(2) value indicates an entry which has been marked inactive by network management, using the ctAliasEntryStatus object in the ctAliasControlTable.

Entries which have been marked inactive may remain in the table to allow consistent mappings between network management stations until an agent needs to free resources.

What is ctAliasInterfaceIsActive?

This TruthValue reports whether this alias entry, viewed in the interface-indexed table, is currently active or has been marked inactive. An admin reviewing all hosts on a given port can use it to filter out stale entries being retained only for consistency rather than genuinely present devices. For example, when auditing what's actually live on a busy access port, the admin ignores rows where ctAliasInterfaceIsActive is false.
