priority Queue on ASA 5510: not working

[t4tauseef33]

Hi, I am not able to insert the following command to enable prioriry queue.

Firewall(config)# priority-queue ?

configure mode commands/options:

Current available interface(s):

Firewall(config)# priority-queue

Secondly, I have a site to site VPN on ASA 5510 and PIX. The ASA is connected to cisco 2960 switches. I am running the Voice phones that are connected to the switches. I have given the cos value 6 on the switches. how can i anable the prioroty of voice over the site to site VPN and on the firewall?

Is this firewall in routed or transparent mode?

Thanks,

My firewall is in routed mode.

Secondly

I am giving the cos value 6 on the switch ports connected to VOIP phones. is the DSCP value cs6 is equivalent to COS 6?

cs6 Match packets with CS6(precedence 6) dscp (110000)
