Diffserv Qos Mode; Diffserv Qos Mode Example - Comtech EF Data CDM-570A Installation And Operation Manual

1. Minimum and maximum bandwidth is only configurable for each of the four
Assured Forwarding classes.
2. Typically, DiffServ is implemented using exclusively Class Selector DSCP or
exclusively Expedited and Assured Forwarding DSCP. The IP Packet
Processor is fully DiffServ compliant and will work with either DiffServ
implementation, or with a combination of both.
WRED – The QoS system supports WRED-based congestion avoidance. WRED can be enable
