Rate shaping overview
Configuring outbound rate shaping for a port
To configure the maximum rate at which outbound traffic is sent out on a port, enter commands
such as the following.
TurboIron(config)#interface e 2
TurboIron(config-if-e10000-2)#rate-limit output shaping 1300
• The configured 1300 Kbps outbound rate shaping on port 2 is rounded up to the nearest value
programmable by the hardware, which is 1344 Kbps. This value is the actual limit on the port
for outbound traffic.
Syntax: [no] rate-limit output shaping <value>
You can specify a value up to the port line rate for <value>.
Configuring outbound rate shaping for a specific priority
To configure the maximum rate at which outbound traffic is sent out on a port priority queue, enter
commands such as the following.
TurboIron(config)#interface e 2
TurboIron(config-if-e10000-2)#rate-limit output shaping 500 priority 7
• The configured 500 Kbps limit for outbound traffic on Priority queue 7 on port 2 is rounded up
to the nearest multiple of 504 Kbps, which is 504 Kbps.
Syntax: [no] rate-limit output shaping <value> priority <priority-queue>
You can specify a value up to the port line rate for <value>.
Specify 0-7 for <priority-queue>.
Configuring outbound rate shaping for a trunk port
This feature is supported on individual ports of a static trunk group. However, it is not supported on
LACP trunk ports on devices.
To configure the maximum rate at which outbound traffic is sent out on a trunk port, enter the
following on each trunk port where outbound traffic will be shaped.
TurboIron(config)#trunk e 13 to 16
TurboIron(config-trunk-13-16)#config-trunk-ind
TurboIron(config-trunk-13-16)#rate-limit output shaping ethe 15 651
TurboIron(config-trunk-13-16)#rate-limit output shaping ethe 14 1300
The above commands configure an outbound rate shaper on port 14 and port 15.
• The configured outbound rate shaper of 651 Kbps on port 15 is rounded up to 704 Kbps. The
configured outbound rate shaper of 1300 on port 14 is rounded up to 1344 Kpbs.
Syntax: [no] rate-limit output shaping ethernet <portnum> <value>.
You can specify a <value> up to the port line rate.
Displaying rate shaping configurations
To display the configured outbound rate shaper on a device, enter the following command.
