Description: Manages IP and MAC access control list configuration and statistics on Cisco devices.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCO-ACL-MIB?

CISCO-ACL-MIB is a Cisco-proprietary module for configuring and monitoring Access Control Lists (ACLs) on Cisco routers and switches, part of the security/traffic-filtering technology area. It exposes configuration data (ACL name, address type, ordered permit/deny rule entries) as well as runtime statistics such as per-rule hit/match counters used to see which filtering rules are actually being triggered by traffic. In terms of device status monitoring, this MIB is primarily useful for verifying that security policy is active and functioning correctly (row status of ACL entries, whether an ACL is correctly bound to an interface) rather than for hardware health, giving operators visibility into software-level policy enforcement state. It is a self-contained Cisco enterprise MIB but conceptually parallels IETF ACL/policy MIB work and depends on standard SNMP conventions like RowStatus and InetAddressType. It is typically deployed in enterprise and service-provider networks to audit and troubleshoot Cisco IOS/IOS-XE ACL configuration and usage across many interfaces, where reviewing each Cisco ACL ACE entry helps confirm security policy is enforced as intended.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-ACL-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Cisco routers
  • Cisco switches

Monitoring Examples

An administrator would poll caAclIPV4ACECfgTable (indexed by caAclIndex and caAclIPV4ACESequenceNumber) to review each rule's caAclIPV4ACEAction, caAclIPV4ACEProtocol and caAclIPV4ACESourceAddress, confirming the ACL matches intended security policy. Cross-referencing caAclCfgTable's caAclName and caAclRowStatus with per-rule hit counters lets the admin spot ACLs that never match any traffic (suggesting a misconfigured source address or unused rule) or rules generating unexpectedly high hit counts (suggesting an attack or misrouted traffic). A sudden change in caAclRowStatus from active to notInService would flag an ACL that was accidentally disabled.

What Can Be Monitored

  • ACL configuration status
  • per-rule hit/match counts
  • ACL rule action (permit/deny)
  • protocol and source address filters
  • ACL interface binding
  • row/administrative status of ACL entries

How to Use in IPNetwork Monitor

Example using caAclIntfStatsPackets OID:

Select a Cisco router or switch (ACLs) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type caAclIntfStatsPackets into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The total number of packets that match this counter label. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline (in packets), since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
