Symptoms

If the SNMP configuration includes a long list of allowed-addresses in the configuration then it can impact SNMP performance.

Impact

Potentially slow SNMP response.

Conditions

-- The SNMP daemon consults a system file to determine whether a request can be serviced. -- There is a long list of allowed addresses in the configuration.

Workaround

Make the list of allowed addresses be the minimum set of your clients.

Fix Information

The daemon code is now more efficient.
