hcxStuL2CurrArpIpv4FiltStat
Module: COM21-HCXSTU-MIB
OID (symbolic): COM21-HCXSTU-MIB::hcxStuL2CurrArpIpv4FiltStat
OID (numeric): 1.3.6.1.4.1.1141.2.55.1.1.18
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: Contains the number of ARP for IPv4 packets filtered in the current 15 min collection period.
What is hcxStuL2CurrArpIpv4FiltStat?
This Gauge32 tallies ARP-for-IPv4 packets filtered by the STU in the current 15-minute period. ARP is essential for IPv4 hosts to resolve addresses, so a climbing count here signals that address-resolution broadcasts from the customer's LAN are being dropped, which will manifest as IPv4 connectivity that never comes up. For example, a newly connected router that repeatedly ARPs for its gateway would show up as a steadily increasing hcxStuL2CurrArpIpv4FiltStat if that ARP traffic is being filtered on this STU.
