expressGSSwitchSTPConfig
Module: EXPRESSGS-MIB
OID (symbolic): EXPRESSGS-MIB::expressGSSwitchSTPConfig
OID (numeric): 1.3.6.1.4.1.343.6.13.5.1.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: When set to ieee8021dStp(1), the switch executes spanning tree conformant to the IEEE 802.1D bridging standard. The switch runs one instance of spanning tree.
When set to stpPerVlan(2), the switch executes a separate instance of spanning tree for each virtual LAN. This configuration conforms to the model that instances of virtual LANs within the switch are separate virtual bridging functions. This method may not work well with bridge/routers that are also running spanning tree.
When set to twoLayerStp(3), the switch executes a two-layer spanning tree to prevent loops. Two layer spanning tree creates a higher 'plane' of spanning tree between VLAN devices. This method of running spanning tree is 'plug and play' with bridge/router type devices and also scales better than the other two methods for large environments.
When set to disable(4), spanning tree is disabled in the switch.
What is expressGSSwitchSTPConfig?
Selects the spanning-tree operating model for the whole switch: ieee8021dStp(1) runs a single classic instance, stpPerVlan(2) runs a separate instance per VLAN, twoLayerStp(3) adds a higher plane of spanning tree that interoperates better with external bridge/routers, or disable(4) turns STP off entirely. An admin chooses twoLayerStp(3) in large multi-VLAN networks that also contain third-party routers running standard spanning tree.
