hm2RingCplNetCoupling

Module: HM2-L2REDUNDANCY-MIB

OID (symbolic): HM2-L2REDUNDANCY-MIB::hm2RingCplNetCoupling

OID (numeric): 1.3.6.1.4.1.248.11.40.1.8.1.1.16

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Specifies the kind of the coupled net segment. If two HIPER Rings are coupled ringCoupling(1) must be used. In netCoupling(2) the coupled segment is no HIPER Ring topology and the switches in the coupled net segment may be connected with other ports than their ringports.

Notice: if the ring coupling mechanism switches over, in ringCoupling(1) only the address tables of the switches in the two coupled HIPER Rings will be erased, in netCoupling(2) the address tables of all switches in the coupled net will be erased.

What is hm2RingCplNetCoupling?

Chooses whether the coupled segment is another HIPER Ring (ringCoupling) or a general network segment (netCoupling); this also determines whether a coupling switchover clears address tables ring-wide or across the whole coupled net.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.248.11.40.1.8.1.1.16
snmpwalk -v2c -c public <target> HM2-L2REDUNDANCY-MIB::hm2RingCplNetCoupling

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.248.11.40.1.8.1.1.16.1
snmpget -v2c -c public <target> HM2-L2REDUNDANCY-MIB::hm2RingCplNetCoupling.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.248.11.40.1.8.1.1.16.1 i <value>
