igmpAccessListNumber
Module: CISCO-IPMCAST-MIB
OID (symbolic): CISCO-IPMCAST-MIB::igmpAccessListNumber
OID (numeric): 1.3.6.1.4.1.9.10.4.1.1.2.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The number of the access-list which specifies the IP multicast groups for which joins are allowed on this interface. A value of zero is equivalent to no access- list.
What is igmpAccessListNumber?
This specifies the numbered access-list (0-100) that controls which IP multicast groups hosts on this interface are permitted to join via IGMP, per its description, with 0 meaning no restriction is applied. It matters for containing multicast traffic to authorized groups on a per-interface basis, preventing hosts from joining arbitrary or unintended multicast streams. Setting this to an access-list that permits only 239.192.0.0/16 would restrict hosts on that interface to joining only that private multicast range, blocking join requests for anything else.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.10.4.1.1.2.1.1 snmpwalk -v2c -c public <target> CISCO-IPMCAST-MIB::igmpAccessListNumber
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9.10.4.1.1.2.1.1.1 snmpget -v2c -c public <target> CISCO-IPMCAST-MIB::igmpAccessListNumber.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.9.10.4.1.1.2.1.1.1 i <value>
