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>
