Regarding QOS

[mukundh86]

Hi

I need help with configuring a priority for printing applications

Here  is the scenario: Location A has a private IP range of 192.168.0.x and  location B has a private IP range of 192.168.1.x. The priniting traffic  starts from location A to location B. Also there is a VPN tunnel between  the two locations through which the data traffic between the private  networks ttraverse.

The  thing is the printers in location B have a IP of 192.168.1.3 and  192.168.1.7. How do I make sure that the traffic between the 192.168.0.x  and the printers i.e. 192.168.1.7 and 192.168.1.3 have a lesser  priority? I am new to QOS and hence I need help on this. Any links to  good sites that will give a clear picture of how QOS works for this  scenario would help.

Thanks

Do you have any devices before/after the firewall's performing the VPN tunnel?  If no, are the VPN devices ASA/PIX?  Need more info to help determine a proper answer.

When you say:

"How do I make sure that the traffic between the 192.168.0.x  and the  printers i.e. 192.168.1.7 and 192.168.1.3 have a lesser  priority"

in  conjunction with QoS, I am assuming what you are trying to avoid is  that you printer traffic will take up too much bandwidth?  And also if  there is congestion, that "printer traffic" will be queued with a lower  priority then other traffic.

read the following on Policing and Shaping:

so at least you get an idea of the principles it is based on.

Yes. Actually that is what Iam trying to make sure..that the printer takes in less bandwidth.
