3-30 Asynchronous Transfer Mode (ATM) Module Installation and User Guide
Configuring the ATM Module
Configuring a QoS Profile
The ATM module supports eight ingress queues and eight egress queues per port. The
scheduling parameters (minimum bandwidth, maximum bandwidth and priority level)
for these queues are controlled by QoS profiles qp1 through qp8, which are defined
using the existing ExtremeWare
config qosprofile
command.
This command has been enhanced to allow you to configure more module-specific
parameters on a port-by-port basis, including the ability to customize the QoS profile
parameters for individual ingress or egress queues on a specific ATM port.
The syntax and description of the enhanced
config qosprofile
command are
described below.
config red [drop-probability |
low-drop-probability | high-drop-probability]
<percent> {ports <portlist>} Configures the RED drop probability for a
specified port.
Added keywords for low-drop-probability and
high-drop-probability; added optional keyword
and argument to specify ports.
config red min-threshold <percent>
ports <portlist> Configures the minimum queue length threshold
for RED operation on the specified ATM ports.
config qosprofile <qosprofile>
{minbw <percent>} {maxbw <percent>}
{priority <level>} {minbuf <percent>}
{maxbuf <percent>} {<portlist>}
{egress | ingress} Configures a QoS profile.
Added optional egress and ingress keywords.
disable red ports <portlist>
{queue <queue#>} Disables RED on the specified ATM ports.
Added optional keyword and argument to specify
the queue number.
enable red ports <portlist> {queue <queue#>} Enables RED on the specified ATM ports.
Added optional keyword and argument to specify
the queue number.
show ports info detail Displays detailed system-related information.
Command output enhanced to display RED
configuration information.
unconfig diffserv dscp-mapping
ports <portlist> Resets the DSCP mapping tables for the
specified ATM ports to their default values.
