Configuration Example for Setting High and Low Watermark Thresholds
Example 15-14 shows how to set the high and low watermark thresholds for PVC 1/32 on the ATM
subinterface 1/0/0.10. In the example, the high watermark is set to 20 and the low watermark is set to 16.
Example 15-14 Setting High and Low Watermark Thresholds
Router(config)# interface atm 1/0/0.10 point-to-point
Router(config-subif)# pvc 1/32
Router(config-if-atm-vc)# queue-depth 20 16
Verifying Oversubscription and VC Weighting
To verify a virtual circuit oversubscription or weighting configuration, enter any of the following
commands in privileged EXEC mode:
Command Purpose
Router# show atm class-links {vpi/vci | name}
Displays virtual circuit (VC) parameter configurations and
where the parameter values are inherited from.
vpi/ is the virtual path identifier. If you do not specify a VPI
value and the slash character (/), the VPI value defaults to 0.
vci is the virtual channel identifier.
name is the name of the VC.
Router# show atm interface interface
Displays the configuration of the interface you specify,
including the default high and low watermark values.
Router# show atm pvc vpi/vci
Displays the high and low watermarks for the individual PVC
that you specify.
vpi/ is the virtual path identifier. If you do not specify a VPI
value and the slash character (/), the VPI value defaults to 0.
vci is the virtual channel identifier.
Router# show controllers interface
Displays the total subscribed rate of all VCs on the port.
