Module: HP-ICF-ARP-PROTECT
OID (symbolic): HP-ICF-ARP-PROTECT::hpicfArpProtectVlanStatBadIpAddrs
OID (numeric): 1.3.6.1.4.1.11.2.14.11.5.1.37.1.2.1.1.7
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of ARP packets received on untrusted ports that were dropped because they contained an invalid sender IP address, or they contained an invalid target IP address in an ARP response. This count does not increment when IP address validation is not enabled. This count does not increment for VLANs for which Dynamic ARP Protection is not enabled.
What is hpicfArpProtectVlanStatBadIpAddrs?
This read-only Counter32 counts, per its source description, ARP packets from untrusted ports dropped for containing an invalid sender IP address (or invalid target IP in a response), and only increments when IP address validation (the ip bit of hpicfArpProtectValidation) and Dynamic ARP Protection are both enabled for the VLAN. Admins use a growing BadIpAddrs count to catch ARP packets referencing 0.0.0.0, broadcast, multicast, or class E addresses, which are common in certain spoofing or misconfiguration scenarios. For example, a device with a broken DHCP configuration sending gratuitous ARPs with 0.0.0.0 as the sender IP would increment this counter rather than actually being forwarded.
