ipMRouteInterfaceTtl

Module: CTATX-MIB

OID (symbolic): CTATX-MIB::ipMRouteInterfaceTtl

OID (numeric): 1.3.6.1.4.1.97.3.26.1.1.3.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The datagram TTL threshold for the interface. Any IP multicast datagrams with a TTL less than this threshold will not be forwarded out the interface. The default value of 0 means all multicast packets are forwarded out interface.

What is ipMRouteInterfaceTtl?

This read-write INTEGER, defaulting to 0 which forwards all packets, sets the datagram TTL threshold for an interface, below which multicast datagrams will not be forwarded out that interface. An admin sets this to scope how far multicast traffic is allowed to propagate out a given interface. For example, setting this to 32 on a WAN-facing interface prevents multicast packets with a TTL below 32, typically meant to stay local, from being forwarded across that link.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.97.3.26.1.1.3.1.2
snmpwalk -v2c -c public <target> CTATX-MIB::ipMRouteInterfaceTtl

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.97.3.26.1.1.3.1.2.1
snmpget -v2c -c public <target> CTATX-MIB::ipMRouteInterfaceTtl.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.97.3.26.1.1.3.1.2.1 i <value>
