Symptoms

No response to SNMP GET request with an error message 'Timeout: No Response from <ip_address>.' after UCS restore, even though running the TMSH command 'tmsh list sys snmp' reports the correct configuration.

Impact

Any snmpget/snmpwalk operations time out. This occurs because snmpd does not load a new config during UCS restore, so if the previous sys snmp configuration differs from the one applied during UCS restore, the discrepancy causes snmpget/snmpwalk operations to time out,

Conditions

-- The BIG-IP configuration has been restored from UCS. -- There is a difference between the sys snmp configuration before the UCS restore operation and after the UCS restore operation. -- The command 'tmsh list sys snmp' reports the correct configuration.

Workaround

Add a short description to let snmpd reload its config: # tmsh modify sys snmp description test # bigstart restart snmpd

Fix Information

None
