Product and Software: This article applies to all Aruba APs and AirWave versions.
When using AMP to poll SNMP devices (APs) in your network, consider the SNMP Timeout. The default value in AMP is 3 seconds, which means that the AMP server polls all devices and waits 3 seconds for a response. If no response is received in 3 seconds, the server retries the request.
In a large Aruba network (>200 APs), this default value could cause a significant spike in traffic and CPU load on your Aruba controller. Consider changing the SNMP Timeout setting to 30 seconds to allow the multiple devices a chance to respond. The longer time also will reduce the amount of SNMP traffic going through your wireless network.
To set the SNMP Timeout value in AirWave, navigate to Device Setup > Communication > SNMP Settings.
