rcMstpPortLoopGuard
Module: SWITCH-MSTP-MIB
OID (symbolic): SWITCH-MSTP-MIB::rcMstpPortLoopGuard
OID (numeric): 1.3.6.1.4.1.8886.6.1.24.3.1.17
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Port mstp loop protect enable status. If a port in some instance did not received any bpdu in three times of hello-time, it will age and reselect. If there was no link fault in the tree but other reason lead to bpdu loss, reselect would create a loopback in the topology. To prevent this, a loop guard enabled port will not age in any case
What is rcMstpPortLoopGuard?
Enables (enable(1)) or disables (disable(2), the default) loop guard on this port, which stops an alternate/root port from aging out and reselecting a new role (a potential loop source) if it simply stops receiving BPDUs without an actual link failure.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.8886.6.1.24.3.1.17 snmpwalk -v2c -c public <target> SWITCH-MSTP-MIB::rcMstpPortLoopGuard
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.8886.6.1.24.3.1.17.1 snmpget -v2c -c public <target> SWITCH-MSTP-MIB::rcMstpPortLoopGuard.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.8886.6.1.24.3.1.17.1 i <value>
