Describes DSCP values applied to TACACS+ packets, explaining how traffic marking optimizes packet handling and prioritization for TACACS+ communication in managed networks.
A Differentiated Services Code Point (DSCP) marking feature is a Quality of Service traffic-classification feature that sets DSCP values for outgoing TACACS+ packets.
-
Differentiated Services divides traffic into classes and forwards packets to the corresponding classes.
-
DSCP is a 6-bit field in the Type of Service byte in the IP header.
-
For a single connection, the DSCP value is set on the socket while connecting to the server.
-
For multiple connections, the DSCP value is set on the available open sockets.
-
Use the tacacs-server ipv4 command to set the DSCP value.
