Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Chapter: Monitoring WAAS Using SNMP
Monitoring WAAS Using SNMP
This chapter describes how to use Simple Network Management Protocol (SNMP) to monitor your WAAS devices. SNMP is an interoperable standards-based protocol that allows for external monitoring of WAAS devices through an SNMP agent.
For more information about using and configuring SNMP, see the "Configuring SNMP Monitoring" chapter in the Cisco Wide Area Application Services Configuration Guide.
This chapter contains the following sections:
•
Information About Supported MIBs
•Viewing and Enabling SNMP Traps
•Information About Common SNMP MIB OIDS
•Viewing and Configuring SNMP Triggers
Information About Supported MIBs
This section describes the Cisco-specific MIBs that are supported by WAAS as follows:
Downloading Supported MIBs
All supported MIB files can be downloaded from the following Cisco FTP locations:
•ftp://ftp.cisco.com/pub/mibs/v2
•ftp://ftp.cisco.com/pub/mibs/v1
The MIB objects that are defined in each MIB are described in the MIB files and are self-explanatory.
Viewing and Enabling SNMP Traps
You can view the SNMP traps options available on the WAAS system by choosing My WAN > Device Group > AllDevicesGroup > Configure > Monitoring > SNMP > General Settings. The SNMP General Settings window appears (see Figure 3-1).
Figure 3-1 SNMP General Settings Window
For information about enabling SNMP traps from the SNMP General Settings window, see the "Configuring SNMP Monitoring" chapter in the Cisco Wide Area Application Services Configuration Guide.
Information About Common SNMP MIB OIDS
This section describes the common SNMP trap OIDs.

Description |
A Content Engine data drive failed. This object supersedes ciscoContentEngineDataDiskFailed. Additional information about the error is logged to syslog. |
Viewing and Configuring SNMP Triggers
You can view and configure SNMP triggers on the WAAS system. You can configure custom triggers to generate additional SNMP traps for other MIB objects of interest to your particular configuration.
There are six default triggers on the WAE. When default triggers are deleted and the configuration is saved, reloading the device brings them back. Figure 3-2 shows the default triggers.
Procedure
Step 1 Choose My WAN > Device Group > AllDevicesGroup > Configure > Monitoring > SNMP > Trigger.
The Trigger List Entries window appears, displaying the list of default and configured triggers (Figure 3-2).
Figure 3-2 SNMP Trigger List
Step 2 To create a trigger, from the Trigger List Entries window, click the create icon.
The Create new SNMP Trigger window appears (Figure 3-3).
Figure 3-3 Create SNMP Trigger
Step 3 Configure the new SNMP trigger.
For information about configuring an SNMP trigger, see the see the "Configuring SNMP Monitoring" chapter in the Cisco Wide Area Application Services Configuration Guide.
