Module: CISCOSB-BRIDGE-SECURITY
OID (symbolic): CISCOSB-BRIDGE-SECURITY::rlIpArpInspectVlanNumOfArpForwarded
OID (numeric): 1.3.6.1.4.1.9.6.1.101.112.3.6.1.4
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Total number of forwarded ARP packets, packets which were validated by ARP inspection
What is rlIpArpInspectVlanNumOfArpForwarded?
This read-only Counter32 counts the total number of ARP packets that were validated by ARP inspection and forwarded on a given VLAN. An admin cares because it provides a baseline of normal ARP traffic volume, useful for spotting anomalies when compared against the dropped/mismatched counters on the same VLAN. For example, an admin investigating a suspected ARP attack would compare this forwarded count against the dropped count on the same VLAN to gauge what fraction of ARP traffic is being rejected.
