Using the BayStack 5510 Switch

Viewing history

Ethernet history records periodic statistical samples from a network. A sample is called a history and is gathered in time intervals referred to as "buckets."
Histories establish a time-dependent method for gathering RMON statistics on a port. The default values for history are:

• Buckets are gathered at 30-minute intervals.
• Number of buckets gathered is 50.

Both the time interval and the number of buckets is configurable. However, when the last bucket is reached, bucket 1 is dumped and "recycled" to hold a new bucket of statistics. Then bucket 2 is dumped, and so forth.

To view RMON history:

1. From the Device Manager main menu, choose RMON > Control > History
2. Select an RMON entry by highlighting the desired port.
3. Click the RMON tab.

The RMON tab opens.
