tnExtMstpCistBpduGuard
Module: TN-XSTP-MIB
OID (symbolic): TN-XSTP-MIB::tnExtMstpCistBpduGuard
OID (numeric): 1.3.6.1.4.1.868.2.5.111.2.1.1.2
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This object control whether a port explicitly configured as Edge will disable itself upon reception of a BPDU.The port will enter the error-disabled state, and will be removed from the active topology.
What is tnExtMstpCistBpduGuard?
Controls whether a port explicitly configured as Edge shuts itself down (enters error-disabled state, removed from the active topology) the moment it receives a BPDU. Enable this on access ports to protect against a rogue switch or loop being plugged into what should be an end-device-only port.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.111.2.1.1.2 snmpwalk -v2c -c public <target> TN-XSTP-MIB::tnExtMstpCistBpduGuard
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.111.2.1.1.2.1 snmpget -v2c -c public <target> TN-XSTP-MIB::tnExtMstpCistBpduGuard.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.868.2.5.111.2.1.1.2.1 s <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> tnExtMstpCistBpduGuard.1
