Reports which port on this switch is currently selected as the root port, i.e. the port providing the lowest-cost path toward the root bridge. An admin checks this to confirm traffic toward the root is flowing over the expected uplink.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.12.1.2.8.2.1.1.7 snmpwalk -v2c -c public <target> CTRON-SFPS-VSTP-MIB::vlanSpanningTreeSwitchRootPort
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.12.1.2.8.2.1.1.7.1 snmpget -v2c -c public <target> CTRON-SFPS-VSTP-MIB::vlanSpanningTreeSwitchRootPort.1
