ipMulticastInterfaceState
Module: CROUTE-MIB
OID (symbolic): CROUTE-MIB::ipMulticastInterfaceState
OID (numeric): 1.3.6.1.4.1.81.31.1.11.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The current state (operational) of the IP Multicast from IP Multicast point of view. It depends on global ipMRouteEnable status and Multicast interface status. Inactive - set by the device (status), Global IP multicast is disabled or Multicast is disable on this interface. Active - set by the device (status), Global IP multicast is enable and Multicast is active on this interface.
What is ipMulticastInterfaceState?
This read-only enumerated integer reports whether IP multicast is actually operational on this interface, depending on both the device's global multicast enable status and this interface's own multicast configuration. An admin checks this to confirm multicast forwarding is truly active on an interface rather than assuming it is because the interface-level setting looks correct. For example, if global IP multicast is disabled device-wide, this object would show inactive(2) even if this interface's own multicast configuration appears otherwise fine.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.31.1.11.1.3 snmpwalk -v2c -c public <target> CROUTE-MIB::ipMulticastInterfaceState
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.81.31.1.11.1.3.1 snmpget -v2c -c public <target> CROUTE-MIB::ipMulticastInterfaceState.1
