Usage

Using Cisco routers, ICA traffic can be prioritized by two distinct methods:

Priority Queuing and Custom Queuing. The following sections define and

describe these methods in detail. They also provide the necessary commands

required as input at the router command interpreter. These sections assume that

the user is knowledgeable in using Cisco routers and has the proper authorization

to make such changes. All commands in these sections are given to the router

from the privileged level of the EXEC command interpreter.

Priority Queuing

Priority Queuing allows you to set up a priority on a particular protocol or port

number. Anytime a buffer of that protocol or port number is transmitted, it is

given high, medium, or low priority.

By using this method, however, other protocols can be limited if there is

significant priority traffic running through the router. For example, during periods

of intense prioritized ICA traffic, there would not be sufficient network bandwidth

for an FTP session or non-ICA print job.

The steps required to set up a priority queue are listed below:

1. At the Router # command prompt, type config terminal. This places the

system in configuration mode.

2. Configure a priority list (1-16) and name the IP protocol as the one to

prioritize. Specify the transport layer protocol and port number (TCP 1494) to

be prioritized. At the Router#(config) prompt, type:

priority-list 1 protocol ip high tcp 1494

3. Assign a default level of prioritization. At the Router#(config) prompt, type:

priority-list 1 default low

In this case, protocols that do not fall into category 1 default to low priority.

4. Specify the queue sizes. This step is optional. See the Cisco documentation for

additional information.
