gsESwitchSTPConfig
Module: GIGAswitchEthernet-MIB
OID (symbolic): GIGAswitchEthernet-MIB::gsESwitchSTPConfig
OID (numeric): 1.3.6.1.4.1.36.2.18.39.5.1.1.1
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 gsESwitchSTPConfig?
Selects the switch's overall Spanning Tree architecture: ieee8021dStp(1) runs one standard 802.1D STP instance, stpPerVlan(2) runs a separate STP instance per VLAN (may not play well with routers also running STP), twoLayerStp(3) adds a higher STP 'plane' between VLAN devices for better plug-and-play scaling in large environments, and disable(4) turns STP off entirely. Admins pick twoLayerStp(3) in large multi-VLAN networks needing to interoperate cleanly with bridge/router devices also running STP.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.36.2.18.39.5.1.1.1 snmpwalk -v2c -c public <target> GIGAswitchEthernet-MIB::gsESwitchSTPConfig
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.36.2.18.39.5.1.1.1.1 snmpget -v2c -c public <target> GIGAswitchEthernet-MIB::gsESwitchSTPConfig.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.36.2.18.39.5.1.1.1.1 i <value>
