SNMP Overview
PacketWise includes a Simple Network Management Protocol (SNMP) agent
that supports the RFC 1213/MIB-II standard and Packeteer enterprise Management
Information Base (MIB). Using an SNMP management program, you can:
- Poll the Packeteer unit for status information
- Read current values for the options described in the Packeteer proprietary
MIB
- Retrieve response time measurement information from PacketWise
You can configure PacketWise to send unsolicited messages to any SNMP
trap listener. These messages fall into two categories.
- PacketWise Trap messages report alarm conditions configured
by default in PacketWise, for example a Power Supply Failure message
is sent if a Packeteer unit's power supply fails. These are generally
the same alarm conditions as might be reported at login to the browser
interface on the Info page. See Packeteer
SNMP Traps for a list of supported traps.
- Event Trap messages alert you to incidents you explicitly configure
PacketWise to report. Use the event configuration commands in the command-line
interface to set up the events to be reported. In the default state,
no Event Traps will be sent. See Overview
of Event Notification for more information on configuring events.
SNMP and ReportCenter
ReportCenter is a Packeteer software package designed to create various
types of reports on the performance of a network equipped with Packeteer
products. You can specify the IP address of a ReportCenter PC as an SNMP
trap destination. The SNMP trap listener incorporated in ReportCenter
will store Generic and Event Traps in a database for use in Generic Trap
Reports and Event Trap Reports.
Supported SNMP MIBs
Packeteer is the authoritative source of the following MIB files:
|
packeteer.mib
|
Packeteer's SNMP MIB
This MIB contains the variables that you can query
on the Packeteer unit. There are three tables for measurement data.
The Link table contains measurement variables about each physical
network interface on the Packeteer unit. The Partition and Class
tables contain measurement variables about each defined partition
and traffic class, respectively.
In addition to measurement variables, the MIB
contains a number of predefined traps; see Packeteer
SNMP Traps for a description of the traps included in the Packeteer
MIB.

|
packeteerRTM.mib
|
Packeteer's Response Time Measurement MIB
This MIB contains the measurement variables related
to PacketWise's Response Time Measurement (RTM) feature, including
variables that track delay (total, network, and server), thresholds,
and slow transactions. There are seven tables for response time
configuration information or data about classes in the traffic tree.
For more information about RTM, see RTM
Overview.
Note: Since RTM is not available on ISP
models, it is not necessary to download this MIB if you are using
PacketShaper ISP.

These MIB files can be downloaded from the Packeteer support site; see
Use
Packeteer MIBs.
Several variables in the following standard MIBs are also supported:
Note: Suggested source for these files: http://www.ietf.org
|
rfc1213.mib
|
The MIB-II file
|
|
rfc1493.mib
|
Two groups from this standard bridge MIB are
supported: dot1Base and dot1dTp
|
Setting Access Permissions
By default, SNMP is turned off until you set the look community string.
You must set the look community string so that PacketWise MIB information
can be accessed by network management platforms and network management
stations. Once the touch community string is set, you can use a network
management platform, such as HP OpenView, to set MIB variables.
To set the PacketWise read and write community strings via the browser
interface, see Configure
PacketWise for SNMP Support. From the command-line interface, use
the setup
snmp command.
MIB-II Support
PacketWise allows SNMP get and set commands for the following
MIB-II groups and objects:
|

Setting MIB-II Variables
To set the sysContact, sysName, and sysLocation MIB-II variables, you
need to use your SNMP Management Station. You cannot set these variables
in PacketWise's browser or command-line interface. For further information
about using SNMP sets, you can download the Packeteer SNMP User Guide:
- On the Packeteer support website, navigate to Software.
- Go to Software Utilities.
- Download the SNMP Guide for PacketWise 6.0.
