What Is ARISTA-IP-MIB?

ARISTA-IP-MIB is a proprietary Arista Networks module extending standard IP-layer statistics with additional per-interface, per-IP-version counters not covered by generic IETF IP MIBs. It exposes a per-interface statistics table breaking down inbound and outbound packet and octet counts, separately tracking unicast traffic, across both IPv4 and IPv6. This is primarily a performance/traffic monitoring module, letting operators baseline and detect anomalies in per-interface IP traffic volume, such as a sudden drop in aristaIpIfStatsInPkts indicating an upstream connectivity problem. It explicitly supplements the standard IP-MIB and IF-MIB by providing Arista-specific statistics not present in those base modules. It is deployed on Arista EOS switches wherever granular per-interface, per-IP-version traffic accounting is needed beyond what standard MIBs provide. Engineers can download the ARISTA-IP-MIB file directly to load it into their MIB browser.

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

What Can Be Monitored

  • per-interface IP packet counts (in/out)
  • per-interface IP octet counts (in/out)
  • per-interface unicast packet/octet counts
  • traffic breakdown by IPv4 vs. IPv6

Supported Devices

  • Arista Networks EOS switch

Monitoring Examples

An operator would poll aristaIpIfStatsTable, indexed by aristaIpIfStatsIfIndex and aristaIpIfStatsIPVersion, reading aristaIpIfStatsInOctets/aristaIpIfStatsOutOctets for traffic volume and aristaIpIfStatsInUcastPkts/aristaIpIfStatsOutUcastPkts for unicast packet rates. Comparing IPv4 versus IPv6 rows for the same ifIndex reveals the traffic mix on a dual-stack interface. A sudden drop in aristaIpIfStatsInPkts for a given interface and IP version, while the interface stays administratively up, would point to an upstream routing or peering issue rather than a physical link fault.
