snMSTrunkPortIndex
Module: FOUNDRY-SN-SWITCH-GROUP-MIB
OID (symbolic): FOUNDRY-SN-SWITCH-GROUP-MIB::snMSTrunkPortIndex
OID (numeric): 1.3.6.1.4.1.1991.1.1.3.6.2.1.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The primary port of a trunk group. For module with Gig ports, primary port is port 1, 3, 5, 7. For module with 10/100 ports, primary port is port 1, 5, 9, 13, 17, 21.
What is snMSTrunkPortIndex?
This read-only index identifies the primary port in a Multi-Spanning-Tree trunk group, which serves as the anchor point for link aggregation. For Gigabit modules, the primary ports are 1, 3, 5, 7, and for 10/100 modules they are 1, 5, 9, 13, 17, 21. Switch administrators reference this to understand the structure of trunk groups and which port is the designated primary for that bundle.
