For in-band management over the production WAN, the proper marking is DSCP CS2 mapped into the management or operations class with a minimum bandwidth guarantee. Cisco enterprise QoS guidance separates network control traffic from network management traffic. Routing protocol and control-plane traffic should not be diluted by ordinary management flows. CS6 is typically reserved for routing and network- control traffic; EF is reserved for low-latency voice bearer traffic; CS1 is commonly used for scavenger or low-priority traffic. Network management flows such as SSH, SNMP, NTP, FTP-based maintenance, and syslog require reliable delivery, but they should not starve business traffic or real-time services. Therefore, marking with CS2 and mapping the traffic into Class2 is the correct design choice. The bandwidth adjustment should come from a lower-priority class, not from the routing/control or real-time class. Because this is in- band management, the architect must also ensure access control, source restrictions, AAA, logging, and management-plane protection. QoS classification alone does not secure management access; it only gives the traffic an appropriate forwarding treatment over the MPLS WAN.
