The Arista Multilayer Switch must activate a system alert message, send an alarm, and/or automatically shut down when a component failure is detected.

Description
Predictable failure prevention requires organizational planning to address device failure issues. If components key to maintaining the device's security fail to function, the device could continue operating in an insecure state. If appropriate actions are not taken when a network device failure occurs, a denial of service condition may occur that could result in mission failure since the network would be operating without a critical security monitoring and prevention function. Upon detecting a failure of network device security components, the network device must activate a system alert message, send an alarm, or shut down.

Check Text ( C-61809r1_chk )
Determine if the network device activates a system alert message, sends an alarm, and/or automatically shuts down when a component failure is detected. This requirement may be verified by demonstration or configuration review. If the network device does not activate a system alert message, send an alarm, or automatically shut down when a component failure is detected, this is a finding. This is a function of SNMP Traps. Verify the SNMP configuration is present in the output of the "show running-config" command and that SNMP is active via the "show snmp" command.

Configure the network device to activate a system alert message, send an alarm, and/or automatically shut down when a component failure is detected. SNMP is used to fulfill this function. An example SNMP configuration is provided below.
