shape (interface configuration)
shape (interfa ce configurati on)
To specify traffic shaping on an interface, use the shape command. To remove traffic shaping, use the
no form of this command
shape [rate] [percent]
no shape [rate] [percent]
Syntax Description
Defaults D efault is no traffic shaping.
Command Modes Interface transmit queue c onfiguration mode
Usage Guidelines Tr affic shaping is available on all the ports, and it sets an upper limit on the bandwidth.
Some examples of ports that are connected directly to the backplane are as follows:
• Port s on the WS-X4306-GB module
• The two 1000BASE-X ports on the WS-X4 232-GB-RJ module
• The first two ports on the WS-X4418- GB module
• The two 1000BASE-X ports on the WS-X4 412-2GB-TX module
All ports on the 24-port modules and the 48-port modules are multiplexed through a Stub ASIC. Some
examples of ports multiplexed t hrough a Stub ASIC are as follows:
• 10/ 100 ports on the WS-X4148-R J45 module
• 10/ 100/1000 ports on the WS-X4 124-GB-RJ45 module
• 10/ 100/1000 ports on the WS-X4 448-GB-RJ45 module
Examples This example shows how to configure a maximum bandwidth (70 percent) for the interface fa3/1:
Switch(config)# interface fastethernet3/1
Switch(config-if)# tx-queue 3
Switch(config-if-tx-queue)# shape 70m
Switch(config-if-tx-queue)#
rate (Optional) Specifies an average rate for traffic shaping; the range is 16000 to
1000000000. Post-fix notation (k, m, and g) is optiona l and a decimal point is
allowed.
percent (Optional) Specifies a percent of bandwidth for traffic shaping.
