System > RMON > History List
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.
1. Log into your switch management page (see
on page 9).
2. Click on System, click on RMON, and click on History.
3. Review the settings.
