Description: Ring-coupling operating mode . In single(1) mode both coupling ports are local to the switch, switch performs master and slave functions. In dual-master-inband(2) mode second coupling port is on a remote switch, local switch is master, communication over network. In dual-master-outband(3) mode second coupling port is on a remote switch, local switch is master, communication over dedicated control port. In dual-slave-inband(4) mode second coupling port is on a remote switch, local switch is slave, communication over network. In dual-slave-outband(5) mode second coupling port is on a remote switch, local switch is slave, communication over dedicated control port. unknown(6) cannot be set,it's returned when no mode is configured.

What is hm2RingCplCouplingMode?

Selects the ring coupling topology: single (both ports local to this switch acting as both master and slave), or one of the dual-master/dual-slave inband/outband combinations where the partner port sits on a remote switch.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.248.11.40.1.8.1.1.9
snmpwalk -v2c -c public <target> HM2-L2REDUNDANCY-MIB::hm2RingCplCouplingMode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.248.11.40.1.8.1.1.9.1
snmpget -v2c -c public <target> HM2-L2REDUNDANCY-MIB::hm2RingCplCouplingMode.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.248.11.40.1.8.1.1.9.1 i <value>
