casGroupId
Module: ACMIB
OID (symbolic): ACMIB::casGroupId
OID (numeric): 1.3.6.1.4.1.1751.2.18.5.20.1.1.8
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The identifier to associate a group of CAS trunks/lines which have same reachability. When SG is disabled, it must be specified with a non-zero value. When SG is enabled, the value should be set to zero which indicate no routing performed based on the value.
What is casGroupId?
This OID groups multiple CAS trunks together when signaling gateway (SG) is disabled, allowing trunks with the same destination to be managed as a unit for call routing. Network engineers assign matching group IDs to trunks that reach the same remote switch or carrier, so the call processor knows which trunk group to use for outbound calls to that destination. Setting trunks to group ID 5 (with SG disabled) groups them logically so outbound calls to the PSTN automatically pick the next available trunk from that group.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.20.1.1.8 snmpwalk -v2c -c public <target> ACMIB::casGroupId
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.20.1.1.8.1 snmpget -v2c -c public <target> ACMIB::casGroupId.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.5.20.1.1.8.1 i <value>
