Description: In an MSTP Bridge, the Regional Root Identifier component of the Port's MSTI port priority vector, as defined in 13.11, for the MSTI.

What is ieee8021MstpPortDesignatedRoot?

The Regional Root Identifier component of this port's MSTI priority vector, showing which regional root this port currently recognizes for this particular MST Instance.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.6.1.4.1.8
snmpwalk -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpPortDesignatedRoot

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.6.1.4.1.8.1
snmpget -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpPortDesignatedRoot.1
