IronClad Quality of Service (QoS)
December 2000 11 - 27
6. Edit the socket number in the Socket field if needed.
• On a Chassis device, select a number from 0 – 7 from the QoS field’s pulldown menu.
• On a Stackable device, select high or normal from the QoS field’s pulldown menu.
7. Click on the Apply button to apply the new QoS setting to the socket number specified in the Socket field or
click on the Apply To All Sockets button to apply the new QoS setting to all AppleTalk sockets.
8. Select the Save link at the bottom of the dialog, then select Yes when prompted to save the configuration
change to the startup-config file on the device’s flash memory.
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.
BigIron(config)# relative-utilization 1 uplink eth 1/1 downlink eth 1/2 to 1/3
BigIron(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
1. Log on to the device using a valid user name and password for read-write access. The System configuration
dialog is displayed.
2. Click on the plus sign next to Configure in the tree view to expand the list of configuration options.
3. Click on the Port link to display the Port Configuration panel.
4. Click on the Relative Utilization link at the top of the panel to display the Port Uplink Relative Utilization panel,
as shown in the following example:
