Hello! I have a Cisco 806 (broadband router with built-in 4-port
hub,e0) with 12.2 IOS and am wondering how to give one system strict
priority over all other traffic. Here is my setup:



Internet -- Cisco -- SystemA
|--- SystemB
|-- SystemC

Basically, I want all traffic to and from SystemA to have priority
over traffic from Systems B and C and hold this traffic up if
necessary. I can use static or dynamic IPs.

I have tried reading different sources on QoS and VOIP, but there is a
ton of info and although I'll eventually want to understand and
implement a more sophisticated solution, right now, I'm looking for
the sledgehammer

Thanks for any tips/info/or pointers!

Look up "custom queuing" in the Cisco documentation.

In this, the 'sledgehammer' would be priority queuing, I guess. Even
simpler than custom, if all he wants to do is give absolute priority to
traffic from system A.

Ok. so packets can be assigned to priority queues based on the
following:

Protocol type
Interface where the packets enter the router

Since systems share the 4-port hub, specifying the protocol or the
interface won't help. So I assume I need to create an access list with
that one system, and give this access list high priority.

This is what I've come up with (10.10.10.10 is the priority host):

access-list 101 permit ip host 10.10.10.10

priority-list 1 protocol ip high list 101
priority-list 2 default medium

Will that do the trick?

Thanks,
Thomas
