Configuring the Interface Queue Thresholds per Service Category
(Catalyst 8510 MSR and LightStream 1010)
The queue thresholds can be specified for the different levels of service and configured on each interface
queue. The following queue thresholds can be configured:
• Output queue EFCI threshold
• Output queue cell loss priority (CLP) and packet discard (PD) threshold
• ABR relative rate threshold
Note Interface queue threshold per-service category configuration is only possible on switches with FC-PCQ
installed on your route processor.
These queue thresholds can be changed at any time. The result changes the threshold for all connections
of that service category using the interface for output and for any subsequent connections.
Note The CLP and PD discard threshold and ABR relative rate threshold have finer granularity than the
explicit forward congestion indication (EFCI) threshold.
To configure the output threshold, 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-threshold {cbr |
vbr-rt | vbr-nrt | abr | ubr} discard-threshold
disc-thresh-num
Configures the ATM output discard threshold.
Step 3
Switch(config-if)# atm output-threshold {cbr |
vbr-rt | vbr-nrt | abr | ubr} efci-threshold
efci-thresh-number
Configures the ATM output threshold.
Step 4
Switch(config-if)# atm output-threshold abr
relative-rate abr-thresh-number
Configures the ATM output threshold ABR.
