Advanced Quality of Service (QoS) Option L–5 MN-CDM570A
L.1.1.1 Max/Pri QoS Mode Example
Dop these steps:
1. Select Max/Pri QoS mode.
2. Set Modem Tx bandwidth to 2048 Kbps (E1 rate).
3. Configure the Max/Pri QoS rules as follows:

L.1.2 Min/Max (Minimum/Maximum Bandwidth) QoS Mode
In Min/Max mode, up to 32 QoS rules can be configured using source/destination IP subnet,
Layer 3 source/destination port range, and protocol (FTP, UDP, RTP, etc.). For each created rule,
you can also set the QoS treatment, such as guaranteed minimum bandwidth, maximum clipping
bandwidth, WRED enable or disable, and filter rule.
