swL2StpPortRole
Module: DES3016-L2MGMT-MIB
OID (symbolic): DES3016-L2MGMT-MIB::swL2StpPortRole
OID (numeric): 1.3.6.1.4.1.171.11.63.10.2.16.4.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: When the port Enable state is enabled, the port's current port role as defined by application of the Spanning Tree Protocol. If the Port Enable state is disabled, the the port role will be nonstp(7). If the port is in loop-back status, the port role will be loopback(8)
What is swL2StpPortRole?
Reports the port's current Spanning Tree role: root(4) (best path to the root bridge), designated(5) (forwarding for its segment), alternate(2) or backup(3) (blocked, standing by), or nonStp(6)/loopback(7) when STP isn't applicable to the port. This tells an admin at a glance why a given port is or isn't forwarding, without having to trace the full spanning tree topology by hand.
