What is tnERPSSubRingTopologyChange?

When set, indicates that topology changes occurring on this sub-ring should be propagated up into its connected major ring. An admin enables this so a fault or reconfiguration event on the sub-ring correctly triggers an FDB flush and topology update on the major ring as well.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.109.3.2.7.1.2
snmpwalk -v2c -c public <target> TN-ERPS-MIB::tnERPSSubRingTopologyChange

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.109.3.2.7.1.2.1
snmpget -v2c -c public <target> TN-ERPS-MIB::tnERPSSubRingTopologyChange.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.868.2.5.109.3.2.7.1.2.1 s <value>
