cktMcastGroupId
Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::cktMcastGroupId
OID (numeric): 1.3.6.1.4.1.277.1.6.1.1.30
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Multicast group identifier (1..32). This field is 0 for unicast PVCs.
What is cktMcastGroupId?
This assigns this circuit to one of up to 32 multicast groups on the switch, so frames sent to that group get replicated out to every member circuit; a value of 0 means the circuit is a plain unicast PVC and not part of any multicast group. An admin building a broadcast/multicast Frame Relay hub-and-spoke topology, common for SNA or trading-floor broadcast applications, assigns the same cktMcastGroupId to every spoke circuit that should receive the hub's replicated traffic. For example, setting cktMcastGroupId to 5 on 20 branch-office PVCs makes them all members of multicast group 5, so a single frame sent to that group from the hub gets duplicated onto all 20 circuits.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.6.1.1.30 snmpwalk -v2c -c public <target> CASCADE-MIB::cktMcastGroupId
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.6.1.1.30.1 snmpget -v2c -c public <target> CASCADE-MIB::cktMcastGroupId.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.6.1.1.30.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cktMcastGroupId.1
