Chapter 12 Sharing Bandwidth Fairly During Congestion

Interfaces Supporting Class-Based Weighted Fair Queuing

The following describes interface support for class-based weighted fair queuing (CBWFQ):
Interfaces Supporting CBWFQ (Outbound Only)
•
•
•
•
•
•
•
•
* Requires a specific type of hierarchical policy. For more information, see
for Multiple Policy Levels."
Note The router only supports CBWFQ on outbound interfaces.
Interfaces Not Supporting CBWFQ
•
•
•
The router does not support the CBWFQ on inbound interfaces.
Note

Configuring Fair Bandwidth Sharing During Congestion

To configure fair bandwidth sharing using QoS service policies, perform the following required
configured tasks:
