portConfigBpduGuard
Module: G6-STP-MIB
OID (symbolic): G6-STP-MIB::portConfigBpduGuard
OID (numeric): 1.3.6.1.4.1.3181.10.6.2.42.2.1.13
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: When enabled STP attempts from a user port are blocked. This prevents a malicious user from influencing the overall network routing.
What is portConfigBpduGuard?
Controls how this port reacts to unexpected STP BPDUs arriving from what should be a user-facing edge port: disabled takes no special action, dropAndEvent drops the BPDU and logs an event, and blockPort shuts the port down. An admin enables this on access ports to stop a rogue switch plugged in by a user from influencing the network's spanning-tree topology.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3181.10.6.2.42.2.1.13 snmpwalk -v2c -c public <target> G6-STP-MIB::portConfigBpduGuard
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.3181.10.6.2.42.2.1.13.1 snmpget -v2c -c public <target> G6-STP-MIB::portConfigBpduGuard.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.3181.10.6.2.42.2.1.13.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> portConfigBpduGuard.1
