Configuring Physical Interfaces
Physical interface resource management configurations affect only specific interfaces on the switch. The
following sections describe physical interface configuration resource management tasks:
• “Configuring the Interface Maximum Queue Size (Catalyst 8510 MSR and LightStream 1010)”
section on page 9-17
• “Configuring the Interface Queue Thresholds per Service Category (Catalyst 8510 MSR and
LightStream 1010)” section on page 9-19
• “Configuring Interface Output Pacing” section on page 9-21
• “Configuring Controlled Link Sharing” section on page 9-22
• “Configuring the Scheduler and Service Class” section on page 9-24
Configuring the Interface Maximum Queue Size (Catalyst 8510 MSR and
LightStream 1010)
Maximum queue size feature on the Catalyst 8510 MSR and LightStream 1010 ATM switch routers is
used to determine the following:
• Maximum number of cells in the switch fabric queue
• Maximum cell transfer delay (CTD)
• Peak-to-peak cell delay variation (CDV) provided on an output switch interface
Note Interface maximum queue size configuration is only possible on switches with FC-PCQ installed on your
route processor.
Because not all queue size values are supported by the switch fabric, the value installed is displayed, as
well as the configuration value requested. The value installed is always greater than or equal to that
requested.
To configure the maximum queue size, perform the following tasks, beginning in global configuration
mode:
Command Purpose
Step 1
Switch(config)# interface atm card/subcard/port
Switch(config-if)#
Selects the interface to be configured.
Step 2
Switch(config-if)# atm output-queue [force]
{cbr | vbr-rt | vbr-nrt | abr-ubr} max-size
number
Configures the ATM output queue maximum
size.
