ieee8021SpanningTreePortPriority
Module: IEEE8021-SPANNING-TREE-MIB
OID (symbolic): IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreePortPriority
OID (numeric): 1.3.111.2.802.1.1.3.1.2.1.3
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The value of the priority field that is contained in the first (in network byte order) octet of the (2 octet long) Port ID. The other octet of the Port ID is given by the value of ieee8021SpanningTreePort. On Bridges supporting IEEE 802.1t or IEEE 802.1w, permissible values are 0-240, in steps of 16.
The value of this object MUST be retained across reinitializations of the management system.
What is ieee8021SpanningTreePortPriority?
The priority portion of a port's Port ID (paired with the port number to form the full ID); lowering it, in steps of 16 on 802.1t/802.1w bridges, makes this port more likely to be chosen as the segment's designated or root port.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.3.1.2.1.3 snmpwalk -v2c -c public <target> IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreePortPriority
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.3.1.2.1.3.1 snmpget -v2c -c public <target> IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreePortPriority.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.111.2.802.1.1.3.1.2.1.3.1 i <value>
