Description: Arista EOS access control list configuration and hardware match counter statistics.

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 ARISTA-ACL-MIB?

ARISTA-ACL-MIB is an Arista Networks proprietary MIB managing IP Access Control Lists on Arista switches. Its objects cover data-plane ACL support-capability flags, an IP-ACL table (name, read-only flag, statistics-enable flag, incomplete-counters flag), and a rule table (sequence ID, protocol, source/destination address and mask, source/destination Layer 4 port operator/ports, TTL operator/value, tracked flag, fragment handling, TCP flags, and established-connection matching). As a configuration MIB it lets an administrator confirm a specific ACL rule's match criteria — including TCP-flag and established-connection matching — before troubleshooting unexpected traffic filtering. It is deployed on Arista Networks switches. Engineers can download the ARISTA-ACL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ARISTA-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

  • Arista Networks switches

Monitoring Examples

An administrator checks aristaIpAclRuleTcpFlags and aristaIpAclRuleEstablished to confirm a stateful-style ACL rule is correctly matching only established TCP connections on an Arista switch.

What Can Be Monitored

  • IP ACL rule configuration and match criteria

How to Use in IPNetwork Monitor

Example using aristaIpAclRuleStatsPktCount OID:

Select an Arista Networks EOS switch 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 aristaIpAclRuleStatsPktCount 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. This attribute is the number of packets that this ACL rule matched. 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, 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.
