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

This section describes the Cisco-specific MIBs that are supported by WAAS as follows:

MIB
Description

ACTONA-ACTASTOR-MIB

Provides statistics for the CIFS transparent accelerator.

CISCO-CDP-MIB

Displays the ifIndex value of the local interface. For 802.3 repeaters on which the repeater ports do not have ifIndex values assigned, this value is a unique value for the port and is greater than any ifIndex value supported by the repeater. In this example, the specific port is indicated by the corresponding values of cdpInterfaceGroup and cdpInterfacePort, where these values correspond to the group number and the port number values of RFC 1516.

CISCO-CONFIG-MAN-MIB

Represents a model of configuration data that exists in various locations:

running—In use by the running system

terminal—Attached hardware

local—Saved locally in NVRAM or in flash memory

remote—Saved to a server on the network

This MIB includes only operations that are specifically related to configuration, although some of the system functions can be used for general file storage and transfer.

CISCO-CONTENT-ENGINE-MIB

MIB module for the Cisco WAAS device from Cisco Systems. The following objects from this MIB are supported:

cceAlarmCriticalCount

cceAlarmMajorCount

cceAlarmMinorCount

cceAlarmHistTableSize

CISCO-ENTITY-ASSET-MIB

Monitors the asset information of items in the ENTITY-MIB (RFC 2037) entPhysicalTable. This MIB lists the orderable part number, serial number, hardware revision, manufacturing assembly number and revision, firmware ID and revision (if any) and software ID and revision (if any) of relevant entities listed in ENTITY-MIB entPhysicalTable.

CISCO-SMI

MIB module for Cisco Enterprise Structure of Management Information. There is nothing to query in this MIB; it describes the structure of Cisco MIBs.

CISCO-WAN-OPTIMIZATION-MIB

Provides information about the status and statistics associated with the Application Optimizers.The following objects from this MIB are supported:

cwoAoStatsIsConfigured

cwoAoStatsIsLicensed

cwoAoStatsOperationalState

cwoAoStatsStartTime

cwoAoStatsTotalHandledConn

cwoAoStatsTotalOptConn

cwoAoStatsTotalHandedOffConn

cwoAoStatsTotalDroppedConn

cwoAoStatsActiveOptConn

cwoAoStatsPendingConn

cwoAoStatsMaxActiveOptConn

This MIB also provides information about TFO statistics. The following objects are supported:

cwoTFOStatsTotalHandledConn

cwoTFOStatsActiveConn

cwoTFOStatsMaxActiveConn

cwoTFOStatsActiveOptTCPPlusConn

cwoTFOStatsActiveOptTCPOnlyConn

cwoTFOStatsActiveOptTCPPrepConn

cwoTFOStatsActiveADConn

cwoTFOStatsReservedConn

cwoTFOStatsPendingConn

cwoTFOStatsActivePTConn

cwoTFOStatsTotalNormalClosedConn

cwoTFOStatsResetConn

ENTITY-MIB

MIB module for representing multiple logical entities supported by a single SNMP agent. The following groups from this MIB are supported:

entityPhysicalGroup

entityLogicalGroup

The entConfigChange notification is supported. This MIB is documented in RFC 2737.

EVENT-MIB

Defines event triggers and actions for network management purposes. The MIB is published as RFC 2981.

HOST-RESOURCES-MIB

Manages host systems. The term host implies any computer that communicates with other similar computers connected to the Internet. The HOST-RESOURCES-MIB does not necessarily apply to devices whose primary function is communications services (terminal servers, routers, bridges, monitoring equipment). This MIB provides attributes that are common to all Internet hosts, for example, personal computers and systems that run variants of UNIX.

IF-MIB

Supports querying for interface-related statistics including 64-bit interface counters. These counters include received and sent octets, unicast, multicast, and broadcast packets on the device interfaces. All the objects from ifXEntry are supported except for ifCounterDiscontinuityTime. This MIB is documented in RFC 2233.

MIB-II

Internet Standard MIB that is documented in RFC 1213 and is for use with network management protocols in TCP/IP-based Internets. This MIB is found in the RFC1213-MIB file in the v1 directory on the download site (other MIBs are in the v2 directory).

SNMP-COMMUNITY-MIB

Documented in RFC 2576.

SNMP-FRAMEWORK-MIB

Documented in RFC 2571.

SNMP-NOTIFICATION-MIB

Documented in RFC 3413.

SNMP-TARGET-MIB

Documented in RFC 3413.

SNMP-USM-MIB

Documented in RFC 2574.

SNMPv2-MIB

Documented in RFC 1907. This MIB supports the following notifications:

coldStart

linkUp

linkDown

authenticationFailure

SNMP-VACM-MIB

Documented in RFC 2575.


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.

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.
