Description
Use this command to add RMON history groups to the ports on the switch.
History groups enable the switch to capture snapshots of the RMON
statistics of the ports over time. You can view the snapshots with an
SNMP program to look for trends or patterns in the numbers or types of
ingress packets on the ports.
A history group can be applied to just one port and the switch can support
up to eight entries at a time. Thus, you can collect statistics histories on up
to eight ports at a time.
The BUCKETS variable defines the number of snapshots the switch is to
take of the RMON statistics of a port. Different ports can have different
numbers of buckets. The INTERVAL parameter, which is entered in
seconds, specifies how frequently the switch is to take the snapshots of
the statistics. For example, if you want the switch to take one snapshot
every minute for five minutes on a port, you would specify five buckets
(one bucket for each minute) and an interval of sixty seconds.
RMON statistics histories are only viewable from an SNMP application
program. There are no commands in the command line interface for
viewing histories.
