SNMP Traps

MediumLevel 2Automatedaruba-cx

Description

Configuring SNMP (Simple Network Management Protocol) traps in AOS-CX switches enables proactive monitoring and management capabilities within the network infrastructure. SNMP traps act as automated notifications that are sent from the switches to a designated management system whenever specific events or thresholds occur, such as high cpu utilization, port status changes, or aaa server unreachability. This ensures real-time visibility into the health and performance of the switches. AOS- CX switches support multiple SNMP traps, which are either enabled by default or through configuration. PASS requires an SNMPv3 trap/inform receiver. Audited against AOS-CX 'show running-config' output (saved in full); context blocks such as 'password complexity' or 'cli-session' are matched by their indented member lines.

How it is checked

Audit method: Configuration pattern

Pattern: (?m)^snmp-server host \S+ (?:trap|inform) version v3 user \S+

How it is fixed

Fix method: Guidance or infrastructure patch
