What is cmTrunkIfIndex?

cmTrunkIfIndex is a read-only Permanent Interface Identifier using the shelf.slot.port portion to index the trunk-interface table, addressing a specific Ethernet trunk port on a particular SCM in a particular shelf. An administrator uses this to locate the table entry for a given SCM's Ethernet uplink when checking its status via cmTrunkIfOperState. For example, an operator investigating a suspected uplink issue on a specific SCM would use cmTrunkIfIndex to confirm they're looking at the correct shelf and slot's Ethernet trunk entry.
