Chapter 23
Configuring the ATM Traffic-Shaping Carrier Module
Configuring Maximum Thresholds
Note
Any changes to the traffic-shaping configuration take effect upon saving the configurations to NVRAM 
and reloading the switch, or upon performing an OIR on the port adapter in subcard 0 of the ATM 
TSCAM.
Example
The following example shows how to enable VBR traffic shaping:
Switch# configure terminal 
Switch(config)# interface atm 4/0/0
Switch(config-if)# atm traffic shaping enable vbr
Switch(config-if)# end
Switch# copy system:running-config nvram:startup-config
Configuring Maximum Thresholds
The ATM TSCAM supports maximum thresholds for traffic class and for VCs. This section describes 
how to configure these thresholds.
Configuring Maximum Thresholds for Traffic Classes
To configure traffic class thresholds, perform the following steps, beginning in privileged EXEC mode:
Note
Prior to changing the traffic class maximum threshold configuration, you must disable the interface using 
the shutdown command. You do not have to disable the interface when configuring per-VC maximum 
thresholds.
Command
Purpose
Step 1
Switch# show atm vc atm slot/subslot/port
Verifies that the VCs on the interface are in a 
down state.
Step 2
Switch# configure terminal
Switch(config)# 
Enters interface global configuration mode.
Step 3
Switch(config)# interface atm slot/subslot/port
Switch(config-if)# 
Enters interface configuration mode.
Step 4
Switch(config-if)# shutdown
Disables the interface.
Step 5
Switch(config-if)# atm traffic shaping 
thresholds class {best-effort | vbr} maximum 
percent
Sets traffic-shaping thresholds on an interface.
Step 6
Switch(config-if)# no shutdown
Enables the interface.
