About SNMP
Simple Network Management Protocol (SNMP) traps enable you to manage and integrate an existing network management system (NMS) for monitoring. SAM alerts you of any potential problems so that you can quickly discover and diagnose issues. The SNMP traps are enabled for a realm by a realm administrator. SAM supports the following standard MIBs at the appliance level:
• SNMPv2-MIB
• IF-MIB
SAM doesn’t support every object (OID) in every one of these MIBs. See the “IF-MIB traps supported” section and “SNMPv2-MIB traps supported” section for the supported OIDs.
The SNMPv2 MIBs and the IF-MIBs support appliance physical interfaces only: for example, eth0 and eth1. SNMP operations are not supported for virtual software or internal interfaces. In the SNMPv2 MIB, there is a scalar entity, for example, sysObjectID, that tracks the OID value of the Riverbed appliance, which is being managed under the SMI enterprise subtree (1.3.6.1.4.1). This entity creates definitions of new OID value for this MIB object.
This table summarizes the SNMP traps sent from SAM to configured trap receivers.

IF-MIB traps supported
Use this MIB to monitor these appliance interface statistics. RFC 2863 defines this MIB.
Trap and OID | Text |
linkUp (1.3.6.1.6.3.1.1.5.4) | An interface has come online. |
linkDown (1.3.6.1.6.3.1.1.5.3) An interface has gone offline. | An interface has gone offline. |
SNMPv2-MIB traps supported
Use this MIB to monitor these appliance statistics.
Trap and OID | Text |
coldStart (1.3.6.1.6.3.1.1.5.1) | The SNMP daemon has restarted. An appliance is reinitializing itself and its configuration might have been altered. |
authenticationFailure (1.3.6.1.6.3.1.1.5.5) | An appliance has received a protocol message that is not properly authenticated. For example, a query has been made with an incorrect community string. |
