Monitoring, Troubleshooting, and Management

Monitoring, Troubleshooting, and Management tests a structured troubleshooting method and familiarity with Aruba's monitoring surfaces: Central, controller WebUI/CLI, AirWave, syslog, and SNMP. Questions often present a client symptom and ask which layer or command to check.

Monitoring surfaces

  • Aruba Central provides dashboards, alerts, client 360, site health, and AI insights. It is cloud-based and depends on devices being onboarded and connected.
  • The controller WebUI and CLI show live state: APs, clients, roles, sessions, and logs.
  • AirWave provides historical monitoring and reporting for supported devices.
  • Syslog, SNMP traps, and NTP are foundational. NTP matters because certificates and logs depend on correct time.

A troubleshooting order

  • Confirm physical layer and PoE, then AP up state, then SSID availability, then client association, then authentication, then DHCP, then reachability.
  • Use show ap database and show ap active to confirm AP state; show user-table and show station-table to see clients; show datapath session to check flows; show log for events.
  • Packet capture at the AP or controller can distinguish a missing DHCP offer from a policy drop.
  • RF checks include channel utilization, retries, SNR, and client capability. A client that associates at a low rate may be far away or limited by its own radio.

Worked example

A client associates to the SSID but gets no IP address. The AP is up and the user-table shows the client in the initial role. show datapath session shows DHCP requests from the client but no responses. The role policy permits DHCP, so the next check is the VLAN: the virtual AP maps to VLAN 20, but the upstream switch port is not trunking VLAN 20 and there is no DHCP scope for it. Moving the client to the correct VLAN or fixing the trunk resolves the issue. The reasoning: association does not prove DHCP or policy is correct.

Traps that cost marks

  • Jumping to RF when the failure is DHCP or role policy.
  • Reading AP up state as client success.
  • Ignoring NTP skew, which breaks certificates and log correlation.
  • Using show ap database as a client table.
  • Forgetting that a firewall role can silently drop traffic.
  • Treating high RSSI as proof of good performance.
