a3ComVlanIfIgnoreStpFlag
Module: GENERIC-3COM-VLAN-MIB-1-0-1
OID (symbolic): GENERIC-3COM-VLAN-MIB-1-0-1::a3ComVlanIfIgnoreStpFlag
OID (numeric): 1.3.6.1.4.1.43.10.1.14.1.2.1.7
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: Enable/disable STP for this VLAN interface. Setting this object to true will cause the ports on this VLAN to ignore STP BPDUs. When a vlan is first created, the Default value is FALSE, which means that the VLAN uses STP port information
What is a3ComVlanIfIgnoreStpFlag?
This boolean controls whether the ports belonging to this VLAN interface ignore Spanning Tree Protocol BPDUs rather than participating in STP loop prevention. Setting it to true is a deliberate override for topologies where STP shouldn't govern this VLAN's ports, at the risk of allowing a loop that STP would otherwise have blocked. An admin troubleshooting an isolated VLAN with no risk of physical loops might set a3ComVlanIfIgnoreStpFlag to true so its ports stop dropping into blocking state due to unrelated STP topology changes elsewhere.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.10.1.14.1.2.1.7 snmpwalk -v2c -c public <target> GENERIC-3COM-VLAN-MIB-1-0-1::a3ComVlanIfIgnoreStpFlag
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.43.10.1.14.1.2.1.7.1 snmpget -v2c -c public <target> GENERIC-3COM-VLAN-MIB-1-0-1::a3ComVlanIfIgnoreStpFlag.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.43.10.1.14.1.2.1.7.1 s <value>
