packets so they leave containing the new level, you would change

Traffic Class - The packet stream is assigned a maximum bandwidth of

5 Mbps. Bandwidth assignment can only be made at the traffic class

level.

Policy - Specifies the traffic class and the port where the policy is to be

assigned.

Critical Database Critical databases typically require a high bandwidth. They also typically

require less priority than either voice or video.

The policies in Figure 15 assign 50 Mbps bandwidth, with no change to

priority, to traffic going to and from a database. The database is located on

a node with the IP address 149.44.44.44 on port 1 of the switch.
