cnt2XIfInMulticastPkts
Module: CNT21-MIB
OID (symbolic): CNT21-MIB::cnt2XIfInMulticastPkts
OID (numeric): 1.3.6.1.4.1.333.2.1.2.3.1.19
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of packets, delivered by this sub-layer to a higher (sub-)layer, which were addressed to a multicast address at this sub-layer. For a MAC layer protocol, this includes both Group and Functional addresses.
Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime.
What is cnt2XIfInMulticastPkts?
This Counter32 counts packets delivered up to a higher sublayer that were addressed to a multicast, or for MAC-layer protocols, group or functional, address, with discontinuities tied to the interface's counter-discontinuity timestamp. An administrator watches for unexpected growth here as a sign of unwanted multicast traffic reaching a port that shouldn't be receiving it. For example, a rise in cnt2XIfInMulticastPkts on an access port not expected to carry multicast video would suggest a multicast forwarding misconfiguration upstream.
