alHostInPkts
Module: RMON2-MIB
OID (symbolic): RMON2-MIB::alHostInPkts
OID (numeric): 1.3.6.1.2.1.16.16.1.1.2
Node type: OBJECT-TYPE
Type: ZeroBasedCounter32
Access: read-only
Description: The number of packets of this protocol type without errors transmitted to this address since it was added to the alHostTable. Note that this is the number of link-layer packets, so if a single network-layer packet is fragmented into several link-layer frames, this counter is incremented several times.
What is alHostInPkts?
This running count tracks total packets of a specific protocol type arriving at a particular host address since it entered the host table. Network engineers use this to monitor incoming traffic volume and detect if a host is receiving an unexpected flood of frames. Example: alHostInPkts for a printer showing billions of packets in minutes suggests a DoS attack or misconfigured network sending garbage to that address.
