ieee8021MstpDesignatedRoot
Module: IEEE8021-MSTP-MIB
OID (symbolic): IEEE8021-MSTP-MIB::ieee8021MstpDesignatedRoot
OID (numeric): 1.3.111.2.802.1.1.6.1.2.1.7
Node type: OBJECT-TYPE
Type: BridgeId
Access: read-only
Description: In an MSTP Bridge, the Designated Root parameter value, i.e., the Bridge Identifier of the Root Bridge for the MSTI.
What is ieee8021MstpDesignatedRoot?
The Bridge Identifier of the Root Bridge for this MST Instance — the switch this instance currently considers to be its spanning-tree root — useful for confirming the expected switch actually holds the root role for this instance.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.6.1.2.1.7 snmpwalk -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpDesignatedRoot
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.6.1.2.1.7.1 snmpget -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpDesignatedRoot.1
