4.4.2.1.7 Self-generated Traffic Commands
sgt-qos
Syntax sgt-qos
Context config>router
Description This command enables the context to configure DSCP or dot1p re-marking for self-generated
traffic (SGT).
application
Syntax application dscp-app-name dscp {none | dscp-value | dscp-name} [fc-queue fc-name
profile {in | out}]
application dot1p-app-name dot1p {none | dot1p-priority} [fc-queue fc-name profile {in |
out}]
no application {dscp-app-name | dot1p-app-name}
Context config>router>sgt-qos
Description This set of commands configures DSCP marking for self-generated IP traffic or dot1p marking
for self-generated non-IP traffic (specifically, IS-IS and ARP traffic).
When an IP or Layer 3 application is configured using the dscp-app-name parameter, the
specified DSCP name or DSCP value is used for all packets generated by this application
within the router instance in which it is configured. The value set in this command sets the
DSCP value in the egress IP header. The egress QoS policy will not overwrite this value.
When a Layer 2 application is configured using the dot1p-app-name parameter, the specified
dot1p priority value is used for all packets generated by this application within the router
instance in which it is configured.
Only one name or value can be configured per application. If multiple entries are configured,
a subsequent entry overrides the previously configured entry.
The fc-queue option redirects SGT applications to egress data queues rather than the default
control queue by assigning them to a forwarding class. If this option is configured, the profile
state must be set. All packets that are assigned to this forwarding class will be considered
in-profile or out-of-profile based on the configuration. In case of congestion, the in-profile
packets are preferentially queued over the out-of-profile packets.
If the fc-queue option is used with the dscp-app-name application, any configuration done
using the sgt-qos>dscp command is ignored for packets generated by this application, as
illustrated in the following examples:
sgt-qos>application telnet dscp cp1
sgt-qos>dscp cp1 fc af
