Introduction

Figure 1-1: The Probe

The HSSI WanProbe has 32 MB of memory (optionally 64 or 128 MB), and uses FLASH EPROM. Probe firmware upgrades are easily downloaded over the LAN to multiple probes simultaneously. You can also download firmware using the probe’s serial port.

The WanProbe maintains a variety of statistical measurements on network performance, continuously keeping track of traffic levels, errors, and other important trends. Alarm thresholds can be set to a number of parameters to immediately alert the network manager or initiate a packet trace to capture the details of an event for later analysis. Traffic and error levels are monitored for the WAN connection on a per-PCV basis.

In addition to using SNMP and selected RMON MIB groups, the WanProbe uses Agilent private MIB extensions to provide additional capabilities. Multiple SNMP trap addresses, or groups of addresses, can be defined for event notification. A real-time utilization variable provides the alarm capability at instantaneous peaks of network load. An additional Out-of-Band connection to the probe can be established using Serial Link Internet Protocol (SLIP), either directly, using a modem, or by using a data switch.
