Configuration Example Explanation:
1. Defines a Class Map called VoIPClass.
2. Matches any packets that have the ToS field set to IP
Precedence 5 / DSCP 40 and assigns them to VoIPClass.
3. Defines a Policy Map called VoIPPolicy.
4. Creates a Class called VoIPClass and assigns this to the
VoIPPolicy.
5. Allocates 50Kbps of bandwidth to the VoIPClass.
6 & 7.Determines that any data that does not match VoIPClass
should be processed using the "fair-queue" method (i.e., No
Prioritization).
8. Determines the amount of bandwidth available on the Serial
interface – essential for the QoS calculations.
9. Applies the VoIP Policy to any packets that exit the serial
interface. This means that data being received (input) does
not use this policy.
