RMON group 2—History

The RMON History group allows you to sample and archive Ethernet statistics for a specific interface during a specific time interval. History sampling is done per port.

NOTE RMON port statistics must be enabled for the port before an RMON history group can monitor the port.

Data is stored in buckets, which store data gathered during discreet sampling intervals. At each configured interval, the History index takes a sample of the current Ethernet statistics, and places them into a bucket. History data buckets reside in dynamic memory. When the switch is re-booted, the buckets are emptied.

Requested buckets are the number of buckets, or data slots, requested by the user for each His- tory Group. Granted buckets are the number of buckets granted by the system, based on the amount of system memory available. The system grants a maximum of 50 buckets.

You can use an SNMP browser to view History samples, or use the following command:

RS G8000# show rmon history

History MIB Object ID

The type of data that can be sampled must be of an ifIndex object type, as described in RFC1213 and RFC1573. The most common data type for the History sample is as follows:

1.3.6.1.2.1.2.2.1.1.x

The last digit (x) represents the number of the port to monitor. In the CLI, you do not need to enter the History MIB Object ID, because the port is specified when you enter Interface Port mode.
