Wireless Access

So, I have a group of access points that need to have one particular device get priority over any other device that may be connected. The reason for this, is that this particular device will be live streaming events and I can't have things get flaky.

Any suggestions for the best way to do this?

Thanks.

Thanks for the answer.

I don't suppose you have a link to some good information on how to prioritize that traffic?

I'd start with the User Guide and the CLI Reference Guide.

The user guide is not at all helpful in understanding what needs to be done in this situation.

chrisbrizzell,

What device and what application?  Does the device authenticate so that we can identify it and give it a better role?  Does the application use ports so that we can write a firewall policy and apply it?  Is there anything that you can give us about this device to give us an idea where we would start?

Colin - thank you.

These are two laptops. Whether they are streaming video live, or doing something else, I would like them to have priority over any other device on this particular set of APs.

It's not as simple as just setting up generic QoS, because I don't want all video(or voice) traffic to have priority.

Thanks.

Can you define the specific video server that these laptops will be going to? As in, are there specific IP addresses for the video server(s). If so, you could add ACLs to a user role (use derivation rules so that these two laptops get that specific role) to prioritize traffic to those IP addresses.

I suppose using derivation rules I could make sure those laptops get into specific roles, and also that anyone else connecting to these specific APs get put into a "lesser" role.

So now the question becomes -what is the best way to force re-authentication when users connect to one of these access points?

By default, the allowall ACL sets IPv4 and IPv6 traffic to Low Queue.

According to the 6.4 User Guide, page 367:

Queue (optional)
The queue in which a packet matching this rule should be placed.
Select High for higher priority data, such as voice, and Low for lower priority traffic.

So, just set the laptops role with an ACL pointing to those video servers with the Queue set to High. Unless you want to throttle the other users in that area.

I may also throttle the other users.

Thanks.

In that case you may have to put those APs in a different AP Group. Then use a different AAA profile so that they get limited roles by default.
