27. Periodic Monitoring

Introduction

The ESB26 switch monitors its own periodic operation.
For more reliable day-to-day operation, periodic crucial switch functions can be monitored
in the background, alerting the network administrator when monitored indicators vary from
operating norms.
As a troubleshooting tool, periodic monitoring can be used to catch transient conditions as
they occur, and to track irregular behaviors. Because the periodic monitoring facility can
generate SNMP traps, it can be used to trigger other diagnostic data polling based on the
switch's operational status.
Table 27-1 displays the operational indicators that are monitored for ESB26:
