Service Ingress QoS Policy Commands
the same parameters (up to 8 per list). As the no command does not have any additional parameters, it is
possible to remove multiple dscp-names from multiple DSCP statements having different parameters with
one command. If a dscp-name specified in a no command does not exist in any DSCP statement, then the
command is aborted at that point with an error message displayed; any dscp-names in the list before the
failed entry will be processed as normal but the processing will stop at the failed entry so that the remainder
of the list is not processed.
Removing the dscp-name from the policy immediately removes the dscp-name on all ingress SAPs using the
policy.
Parameters
dscp-name — The DSCP name is a required parameter that specifies the unique IP header ToS byte DSCP
bits value that will match the DSCP rule. If the command is executed multiple times with the same
dscp-name, the previous forwarding class and enqueuing priority is completely overridden by the new
parameters or defined to be inherited when a forwarding class or enqueuing priority parameter is
missing.
A maximum of 64 DSCP rules are allowed on a single policy and a maximum of 8 dscp-names can be
specified in a single statement.
The specified name must exist as a dscp-name. SR OS software provides names for the well-known
code points these can be shown using the command below:
A:PE# show qos dscp-table
