Configuring a utilization list for an uplink port
A
PowerConnect#clear statistics
Syntax: clear statistics
This command clears the values in the following fields of the show sflow display:
• UDP packets exported
• sFlow samples collected
NOTE
This command also clears the statistics counters used by other features.
Configuring a utilization list for an uplink port
You can configure uplink utilization lists that display the percentage of a given uplink port
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 bandwidth that was utilized by the
downlink ports over the most recent 30-second interval.
You can configure up to four bandwidth utilization lists.
Command syntax
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 as the uplink port and ports2 and 3 as the
downlink ports.
PowerConnect(config)#relative-utilization 1 uplink eth 1 downlink eth 2 to 3
PowerConnect(config)#write memory
Syntax: [no] relative-utilization <num> uplink ethernet <portnum> [to <portnum>] downlink
ethernet <portnum> [to<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 numbers you specify after the parameters indicate
the uplink ports.
