AMON Advanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities. communications between ArubaOS and AirWave is sent over 8211/udp (same as PAPI Process Application Programming Interface. PAPI controls channels for ARM and Wireless Intrusion Detection System (WIDS) communication to the master controller. A separate PAPI control channel connects to the local controller where the SSID tunnels terminate. ). AMON Advanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities. gathers all the client data for AirWave to scale for the huge amounts of data being sent by the controller to AirWave as SNMP Simple Network Management Protocol.

Salient Features

The following are the salient features of AMON Advanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities. feature:

AMON Message Size Changes

Data communication between managed devices and AirWave servers has shifted from the SNMP Simple Network Management Protocol. SNMP is a TCP/IP standard protocol for managing devices on IP networks. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, and more. It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention.  model to the faster, more reliable, and scalable AMON Advanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities. model. Though the SNMP Simple Network Management Protocol. SNMP is a TCP/IP standard protocol for managing devices on IP networks. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, and more. It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention.  model can still be used to communicate data, users generally encounter delayed AirWave updates and high CPU Central Processing Unit. A CPU is an electronic circuitry in a computer for processing instructions. usage.

The AMON Advanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities. packet size has been capped at a default value of 1264 bytes to reduce the amount of fragmentation and message loss that typically occurs in larger packet sizes, which can force customers to fall back to the SNMP Simple Network Management Protocol. SNMP is a TCP/IP standard protocol for managing devices on IP networks. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, and more. It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention.  model. Message size has been capped at 1264 bytes to allow for the addition of AMON Advanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities. headers and PAPI Process Application Programming Interface. PAPI controls channels for ARM and Wireless Intrusion Detection System (WIDS) communication to the master controller. A separate PAPI control channel connects to the local controller where the SSID tunnels terminate. , UDP User Datagram Protocol. UDP is a part of the TCP/IP family of protocols used for data transfer. UDP is typically used for streaming media. UDP is a stateless protocol, which means it does not acknowledge that the packets being sent have been received., or IP headers. Each packet only contains one message to further reduce the amount of overall message loss, as the loss of even a single fragment can render an entire message invalid. To reduce fragmentation in case of IPv6 AMON Advanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities. packets, the size can be configured to 1152 bytes.

The AMON Advanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities. packet size can be modified using the following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. command:

amon msg-buffer-size <msg-buffer-size>

With the additional message load due to the smaller packet size and 1:1 message to packet ratio, output has also been increased from 10 second intervals to 1 second intervals to distribute packets more evenly, helping maintain a more stable and less congested traffic flow.

Secure AMON Feed to AirWave

Starting from ArubaOS 8.1 new enhancements have been made to the AMON Advanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities. infrastructure that includes DTLS Datagram Transport Layer Security. DTLS communications protocol provides communications security for datagram protocols. support both on IPv4 and IPv6. DTLS Datagram Transport Layer Security. DTLS communications protocol provides communications security for datagram protocols. provides secure communication over unreliable sessions with minimal overhead and still provides real-time response.
