Module: ACMEPACKET2-ENVMON-MIB
OID (symbolic): ACMEPACKET2-ENVMON-MIB::apSysARPCapacity
OID (numeric): 1.3.6.1.4.1.9148.3.2.1.1.8
Node type: OBJECT-TYPE
Type: SysMgmtPercentage
Access: read-only
Description:
The percentage of ARP table (in CAM) utilization.
What is apSysARPCapacity?
This OID shows how full the Address Resolution Protocol table is, as a percentage of available space. Engineers watch this to detect excessive ARP entries, which could indicate a network scanning attack or misconfiguration. For example, '72%' means the ARP table is moderately full and approaching potential saturation.
