CISCO 2950 QOS COS

I have a CISCO 2950 sitting outside my ASA firewall |

There is a video conferencing unit that also sits outside the firewall on a 2950 port. So it is using a public IP address.

We used to have it sitting inside the firewall and recently moved it to the outside.

I have reports that the Video Conferencing unit quality is worse by moving it to the outside, Which I do not understand.

I want to make sure that the Video Conferencing unit has packet priority leaving the 2950 heading out to the internet. Which in this case, the next hop is the ISP.

Interface stats look fine |

I was thinking that the egress point would need to have a trusted point for COS/QOS

Is the ASA interface set to same 10M ?

ASKER

yes, that is the ISP's requirement. 10/full

we have hard set the port 10/full

What i want to really know is the COS QOS settings on the port enough to give that port priority of anything leaving the switch.
