DSCP Service Settings

The Differentiated Services Code Point (DSCP) header in an IP packet is used to classify packets. The DSCP header value determines packet priority. As the administrator, you can configure DSCP values for traffic initiated by a device.

DSCP marking for self-initiated traffic is required. You can configure DSCP priority levels for 11 service types. DSCP is always 0 for all self-initiated traffic except OSPF and BGP. Self-initiated packets might be dropped by an intermediate device because of their lower priority.

To Define DSCP Service Settings

  1. Enter the DSCP value for each service. The value must be in the range of 0 to 63. The lowest possible priority setting is 0 (zero).

BGP: The value is set to 48.

OSPF: The value is set to 48.

RIP: The default value is 0.

RIPNG: The default value is 0.

TELNET: The default value is 0.

SSH: The default value is 0.

TFTP: The default value is 0.
