Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches
shape (interface configuration)
shape (interface configuration)
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 Default is no traffic shaping.
Command Modes Interface transmit queue configuration mode
Command History
Usage Guidelines This command is not supported on the Supervisor Engine 6-E and Catalyst 4900M chassis.
Traffic shaping is available on all the ports, and it sets an upper limit on the bandwidth.
When the high shape rates are configured on the Catalyst 4500 Supervisor Engine II-Plus-10GE
(WS-X4013+10GE), the Catalyst 4500 Supervisor Engine V (WS-X4516), and the Catalyst 4500
Supervisor Engine V-10GE (WS-X4516-10GE), the shaped traffic rate may not be achieved in situations
that involve contention and unusual packet size distributions. On the ports that are multiplexed through
a Stub ASIC and connected to the backplane gigaports, the shape rates above 7 Mbps may not be
achieved under worst-case conditions. On ports that are connected directly to the backplane gigaports,
or the supervisor engine gigaports, the shape rates above 50 Mbps may not be achieved under worst-case
conditions.
Some examples of ports that are connected directly to the backplane are as follows:
• Uplink ports on Supervisor Engine II+, II+10GE, III, IV, V, and V-10GE
• Ports on the WS-X4306-GB module
• The two 1000BASE-X ports on the WS-X4232-GB-RJ module
• The first two ports on the WS-X4418-GB module
• The two 1000BASE-X ports on the WS-X4412-2GB-TX module
rate (Optional) Specifies an average rate for traffic shaping; the range is 16000 to
1000000000. Post-fix notation (k, m, and g) is optional and a decimal point is
allowed.
percent (Optional) Specifies a percent of bandwidth for traffic shaping.
Release Modification
12.2(18)EW Support for this command was introduced on the Catalyst 4500 series switch.
