RFC 4594 would suggest using DSCP CS2 (010000xx in the TOS byte; xx is the ECN flags). Section 3.1 discusses the issues with CS7, which is the DSCP counterpart to the deprecated IP Precedence 7.

Experts, what is the general opinion of using ipp 7 'network control' for management traffic like: telnet ssh snmp .....
The idea is that ipp 0 1 2 3 4 5 are used for user traffic ipp = 6 is used by default by routing protocols like BGP, OSPF, LDP ...
this leaves out only ipp 7 for management traffic, on the premise that routing and management should not share the same queue and resources.....
Thanks, Luca.
