ipExtIfMulticast
Module: BIANCA-BRICK-IP-MIB
OID (symbolic): BIANCA-BRICK-IP-MIB::ipExtIfMulticast
OID (numeric): 1.3.6.1.4.1.272.4.5.3.1.30
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Enable that multicast frames are accepted from that interface.
What is ipExtIfMulticast?
This switches whether the interface accepts incoming multicast frames at all: on(2) allows them through, off(1) drops them. Turning ipExtIfMulticast off(1) on an interface facing an untrusted network blocks unwanted multicast traffic (and the load it can create) from ever reaching the router's multicast-handling logic. For example, an ISP-facing WAN interface would typically be set to off(1) unless the ISP explicitly delivers multicast services.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.272.4.5.3.1.30 snmpwalk -v2c -c public <target> BIANCA-BRICK-IP-MIB::ipExtIfMulticast
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.272.4.5.3.1.30.1 snmpget -v2c -c public <target> BIANCA-BRICK-IP-MIB::ipExtIfMulticast.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.272.4.5.3.1.30.1 i <value>
