erptrMonitorPortMulticastFrames
Module: DECHUB900-ERPTR-MIB-V3-0
OID (symbolic): DECHUB900-ERPTR-MIB-V3-0::erptrMonitorPortMulticastFrames
OID (numeric): 1.3.6.1.4.1.36.2.18.11.5.1.1.7.3.1.1.3
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: This object is the number of valid multicast frames that have been received on this port. This counter is incremented by one for each frame received on this port whose OctetCount is greater than or equal to minFrameSize and less than or equal to maxFrameSize, whose MAC-layer destination address field contains a multicast-group address, and for which the FCSError and CollisionEvent signals are not asserted.
The approximate minimum time for rollover of this counter is 80 hours.
What is erptrMonitorPortMulticastFrames?
This counter tracks valid multicast frames received on the port (correct size, multicast destination, no FCS or collision errors), rolling over roughly every 80 hours on a busy port. It's useful for spotting unusually high multicast traffic that might indicate a chatty application or misconfigured device on that segment.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.36.2.18.11.5.1.1.7.3.1.1.3 snmpwalk -v2c -c public <target> DECHUB900-ERPTR-MIB-V3-0::erptrMonitorPortMulticastFrames
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.36.2.18.11.5.1.1.7.3.1.1.3.1 snmpget -v2c -c public <target> DECHUB900-ERPTR-MIB-V3-0::erptrMonitorPortMulticastFrames.1
