(SOL9896) The BIG-IP ASM systemmay send SNMP traps to report request violations and requests that the system blocked. However, this level of reporting may not be desired or useful. In some cases, the SNMP network manager may not be able to handlethe volume ofsuch SNMP traps sent by the BIG-IP ASM system. In other cases, the administrator may wantto monitor the same information using a syslog server or a remote logging profile. You can prevent the BIG-IP ASM system from sending SNMP traps for BIG-IP ASM re

Informational: The BIG-IP system resets the Diameter connection when the Diameter message from a peer has an empty value in the Origin-Realm field

$

(SOL12867) When a virtual server using the Diameter profile receives a Capabilities-Exchange-Request (CER) message with an empty Origin-Realm field from a Diameter peer, the virtual server attempts to use the empty Origin-Realm field when sending a Device-Watchdog-Answer (DWA) message to a Diameter peer. As a result, the BIG-IP system stops the DWA message, resets the Diameter connection, and logs an error message that appears similar to the following example in the /var/log/ltm file: 014c0001:3: diameter
