etherMulticastBytesIn
Module: MRV-IN-REACH-ETHERNET-MIB
OID (symbolic): MRV-IN-REACH-ETHERNET-MIB::etherMulticastBytesIn
OID (numeric): 1.3.6.1.4.1.33.11.3.1.2
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: A count of frames successfully received on a particular interface and for which the destination address multicast bit was set. Bytes that are counted by an instance of this object are also counted by the corresponding instance of the ifInOctets object.
What is etherMulticastBytesIn?
This is a running count of bytes received on an InReach Ethernet interface in frames whose destination address had the multicast bit set. Admins use it to see how much of that port's inbound traffic is multicast, useful when troubleshooting multicast applications on the managed network. A spike in etherMulticastBytesIn on an InReach port could indicate a new multicast application or an unexpected multicast storm on that segment.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.33.11.3.1.2 snmpwalk -v2c -c public <target> MRV-IN-REACH-ETHERNET-MIB::etherMulticastBytesIn
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.33.11.3.1.2.1 snmpget -v2c -c public <target> MRV-IN-REACH-ETHERNET-MIB::etherMulticastBytesIn.1
