Histories
RMON histories are snapshots of port statistics. They are taken by the
switch at predefined intervals and can be used to identify trends or
patterns in the numbers or types of ingress packets on the ports on the
switch. The snapshots can be viewed with your SNMP NMS software with
the history group of the RMON portion of the MIB tree.
A history group is divided into buckets. Each bucket stores one snapshot
of statistics of a port. A group can have from 1 to 50 buckets. The more
buckets in a group, the more snapshots it can store.
Perform the following procedure to configure RMON history:
1. From the main menu on the left side of the page, click the
