Module: IEEE8021-MSTP-MIB
OID (symbolic): IEEE8021-MSTP-MIB::ieee8021MstpPortRole
OID (numeric): 1.3.111.2.802.1.1.6.1.4.1.12
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: In an MSTP Bridge, the current Port Role for the Port (i.e., Root, Alternate, Designated, or Backup), for the MSTI.
What is ieee8021MstpPortRole?
The current spanning-tree role of this port for this specific MST Instance: root(1), designated(3), alternate(2), or backup(4) — since MSTIs can differ from the CIST, a port can be forwarding on one instance while blocking on another.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.6.1.4.1.12 snmpwalk -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpPortRole
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.6.1.4.1.12.1 snmpget -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpPortRole.1
