allows you to change the Differentiated Services Code Point (DSCP) marking for
COPS messages that are transmitted or received by the Cisco router. The
command changes the default IP parameters for connections
between the Cisco router and COPS servers in the cable network.
DSCP values are
used in Quality of Service (QoS) configurations on a Cisco router to summarize
the relationship between DSCP and IP precedence. This command allows COPS to
remark the packets for either incoming or outbound connections.
setting is 0 for outbound connections. On default incoming connections, the
COPS engine takes the DSCP value from the COPS server initiating the TCP
affects all TCP connections with all COPS servers.
- For messages transmitted
by the Cisco router, the default DSCP value is 0.
- For incoming connections
to the Cisco router, the COPS engine takes the DSCP value used by the COPS
server that initiates the TCP connection, by default.
dscp command allows the Cisco router to re-mark
the COPS packets for either incoming or outbound connections.
- This command affects all
TCP connections with all COPS servers.
- This command does not
affect existing connections to COPS servers. Once you issue this command, this
function is supported only for new connections after that point in time.
