Description: Arista EOS SNMP transport configuration including TCP and UDP domain management.
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-SNMP-TRANSPORTS-MIB?
This is an Arista Networks (EOS) enterprise MIB defining SNMP transport domain configuration, specifically Arista-specific SNMP transport addressing objects and an authentication-failure trap mechanism. It exposes objects describing the transport domain and source address of SNMP authentication-failure events (aristaAuthFailTrapTDomain, aristaAuthFailTrapSrcTAddress), used to notify management stations when an unauthorized or misconfigured SNMP client attempts access. Rather than hardware/environmental monitoring, its value is in monitoring the software health and security posture of the SNMP management subsystem itself, alerting operators to failed authentication attempts that could indicate misconfiguration or a security probing attempt. It extends the standard SNMP transport-domain/transport-address conventions with Arista-specific trap semantics. It's typically deployed on Arista EOS switches wherever SNMP-based management is used and administrators want visibility into SNMP authentication failures. Network engineers evaluating or troubleshooting this functionality can download the ARISTA-SNMP-TRANSPORTS-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in ARISTA-SNMP-TRANSPORTS-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 EOS switches
Monitoring Examples
A monitoring station would subscribe to traps carrying aristaAuthFailTrapObjects, including the aristaAuthFailTrapSrcTAddress of the offending client and the aristaAuthFailTrapTDomain, e.g., UDP/IP, over which the failed request arrived. Repeated authentication-failure traps from the same source address would indicate either an SNMP client with a stale community string/credentials or a potential unauthorized access attempt against the switch.
What Can Be Monitored
- SNMP authentication failure events
- source transport address of failed SNMP requests
- SNMP transport domain used
