Parameters dscp-app-name — the DSCP application name
Values bgp, dhcp, dns, ftp, icmp, ldp, ntp, ospf, ptp, radius, rsvp, snmp, snmp-notification,
ssh, syslog, tacplus, telnet, tftp, traceroute
dscp-value — the DSCP 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

Notes:
1. 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.
2. 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.
