sgt-qos>application ftp dscp cp1 fc-queue be profile out
sgt-qos>dscp cp1 fc af
In the first example, all packets generated by the Telnet application use DSCP CP1 and map
to FC AF as configured in the dscp command. The dot1p bits of the outgoing packets are
marked from the value that FC AF points to in the egress QoS policy.
In the second example, all packets generated by the FTP application use DSCP CP1 and
map to FC BE as dictated by the fc-queue redirection. The dot1p bits of the outgoing packets
are marked from the value that FC BE points to in the egress QoS policy. Because redirection
is configured, the mapping configured with the dscp command is ignored.
If the fc-queue option is used with the dot1p-app-name application, the dot1p bits of the
outgoing packets are marked with the value set with the dot1p-priority parameter, regardless
of the value in the FC egress queue policy.
The no form of this command resets the DSCP or dot1p value for the application to its default
value and resets the application to use the egress control queue.
Default n/a
Parameters dscp-app-name — the DSCP application name
Values bgp, dhcp, dns, ftp, icmp, igmp, ldp, mld, ndis, ntp, ospf, pim, ptp,
radius, rip, rsvp, snmp, snmp-notification, ssh, syslog, tacplus,
telnet, tftp, traceroute, vrrp
dscp-value — the value that maps to the DSCP name (the value none specifies that the
default DSCP value for the application be used; see Table 28)
Values none | 0 to 63
dscp-name — the DSCP to be associated with the forwarding class. Table 31 lists the
valid DSCP names.
Note: The above behavior applies to all SGT IP applications with the exception of VRRP,
where the dot1p value is always set to 7, regardless of the value in the FC egress QoS
policy.
Note:
• PTP in the context of SGT QoS is defined as Precision Timing Protocol and is an
application in the 7705 SAR. The PTP application name is also used in areas such as
event-control and logging. Precision Timing Protocol is defined in IEEE 1588-2008.
• PTP in the context of IP filters is defined as Performance Transparency Protocol. IP
protocols can be used as IP filter match criteria; the match is made on the 8-bit protocol
field in the IP header.
