Configuring a Utilization List for an Uplink Port

You can configure uplink utilization lists that display the percentage of a given uplink port’s bandwidth that is used by a specific list of downlink ports. The percentages are based on 30-second intervals of RMON packet statistics for the ports. Both transmit and receive traffic is counted in each percentage.

NOTE: This feature is intended for ISP or collocation environments in which downlink ports are dedicated to various customers’ traffic and are isolated from one another. If traffic regularly passes between the downlink ports, the information displayed by the utilization lists does not provide a clear depiction of traffic exchanged by the downlink ports and the uplink port.

Each uplink utilization list consists of the following:

•Utilization list number (1, 2, 3, or 4)

•One or more uplink ports

•One or more downlink ports

Each list displays the uplink port and the percentage of that port’s bandwidth that was utilized by the downlink ports over the most recent 30-second interval.

You can configure up to four bandwidth utilization lists. To do so, use either of the following methods.

USING THE CLI

To configure an uplink utilization list, enter commands such as the following. The commands in this example configure a link utilization list with port 1/1 as the uplink port and ports 1/2 and 1/3 as the downlink ports.

HP9300(config)# relative-utilization 1 uplink eth 1/1 downlink eth 1/2 to 1/3 HP9300(config)# write memory

Syntax: [no] relative-utilization <num> uplink ethernet <portnum> [to <portnum> <portnum>…] downlink ethernet <portnum> [to <portnum> <portnum>…]

The <num> parameter specifies the list number. You can configure up to four lists. Specify a number from 1 – 4.

The uplink ethernet parameters and the port number(s) you specify after the parameters indicate the uplink port(s).

The downlink ethernet parameters and the port number(s) you specify after the parameters indicate the downlink port(s).

USING THE WEB MANAGEMENT INTERFACE
