Self-generated traffic commands (7210 SAS-Mxp, 7210 SAS-R6, and 7210 SAS-R12)

application

Syntax

application dscp-app-name dscp {dscp-value | dscp-name}

application dot1p-app-name dot1p dot1p-priority

no application {dscp-app-name | dot1p-app-name}

Context

config>router>sgt-qos

Platforms

7210 SAS-Mxp, 7210 SAS-R6, and 7210 SAS-R12

Description

This command configures DSCP/dot1p re-marking for self-generated application traffic. When an application is configured using this command, then the specified DSCP name/value is used for all packets generated by this application within the router instance it is configured. The instances can be base router or VPRN service.

Using the value configured in this command does the following.

Sets the DSCP bits in the IP packet.
Maps to the FC.
Based on this FC, the egress QoS policy sets the Ethernet 802.1p and MPLS EXP bits. This includes ARP and IS-IS packets that, because of their nature, do not carry DSCP bits.
The DSCP value in the egress IP header will be as configured in this command.

Only one DSCP name/value can be configured per application. If multiple entries are configured then the subsequent entry overrides the previously configured entry.

The no form of this command reverts to the default value.

Parameters

dscp-app-name

Specifies the DSCP application name.

Values

The following values apply to the base router instance:

bgp, dns, ftp, icmp, igmp, ldp, ndis, ntp, ospf, pim, ptp, radius, rip, rsvp, snmp, snmp-notification, ssh, syslog, tacplus, telnet, tftp, traceroute, vrrp, arp, isis

dscp-value

Specifies a value when this packet egresses the respective egress policy should provide the mapping for the DSCP value to either LSP-EXP bits or IEEE 802.1p (dot1p) bits as appropriate, otherwise the default mapping applies.

Values: 0 to 63

dscp-name

Specifies the DSCP name.

Values: none, be, ef, cp1, cp2, cp3, cp4, cp5, cp6, cp7, cp9, cs1, cs2, cs3, cs4, cs5, nc1, nc2, af11, af12, af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, cp11, cp13, cp15, cp17, cp19, cp21, cp23, cp25, cp27, cp29, cp31, cp33, cp35, cp37, cp39, cp41, cp42, cp43, cp44, cp45, cp47, cp49, cp50, cp51, cp52, cp53, cp54, cp55, cp57, cp58, cp59, cp60, cp61, cp62, cp63

dot1p-priority

Specifies the dot1p priority.

Values: none, or 0 to 7

dot1p-app-name

Specifies the dot1p application name.

Values: arp, isis

dscp

Syntax

dscp dscp-name fc fc-name

no dscp dscp-name

Context

config>router>sgt-qos

Platforms

7210 SAS-Mxp, 7210 SAS-R6, and 7210 SAS-R12

Description

This command creates a mapping between the DiffServ Code Point (DSCP) of the self-generated traffic and the forwarding class.

Self-generated traffic for configured applications that matches the specified DSCP will be assigned to the corresponding forwarding class. Multiple commands can be entered to define the association of some or all 64 DSCPs to a forwarding class.

All DSCP names that define a DSCP value must be explicitly defined.

The no form of this command removes the DSCP-to-forwarding class association.

Parameters

dscp-name

Specifies the name of the DSCP to be associated with the forwarding class. A DiffServ code point can only be specified by its name and only an existing DiffServ code point can be specified. The software provides names for the well known code points.

Values: be, ef, cp1, cp2, cp3, cp4, cp5, cp6, cp7, cp9, cs1, cs2, cs3, cs4, cs5, nc1, nc2, af11, af12, af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, cp11, cp13, cp15, cp17, cp19, cp21, cp23, cp25, cp27, cp29, cp31, cp33, cp35, cp37, cp39, cp41, cp42, cp43, cp44, cp45, cp47, cp49, cp50, cp51, cp52, cp53, cp54, cp55, cp57, cp58, cp59, cp60, cp61, cp62, cp63

fc fc-name

Specifies the forwarding class name. Applications and protocols that are configured under the dscp command will use the configured IP DSCP value.

Values: be, l2, af, l1, h2, ef, h1, nc
