Specifying Precedence for an IPX QoS Policy
To specify the precedence for an IPX QoS policy, enter the following command in
Configure mode:
Configuring SSR Queueing Policy
The SSR queuing policy is set on a system-wide basis. The SSR default queuing policy is
strict priority. To change the queuing policy to weighted-fair queuing on the SSR, enter the
following command in Configure mode:
If you want to revert the SSR queuing policy from weighted-fair to strict priority (default),
enter the following command in Configure mode:
Allocating Bandwidth for a Weighted-Fair Queuing Policy
If you enable the weighted-fair queuing policy on the SSR, you can allocate bandwidth for
the queues on the SSR. To allocate bandwidth for each SSR queue, enter the following
command in Configure mode:
ToS Rewrite
In the Internet, IP packets that use different paths are subject to delays, as there is little
inherent knowledge of how to optimize the paths for different packets from different
applications or users. The IP protocol actually provides a facility, which has been part of
the IP specification since the protocol’s inception, for an application or upper-layer
protocol to specify how a packet should be handled. This facility is called the Type of
Service (ToS) octet.

IPX QoS policy.
