Cisco 3560 QOS Routing Question
Hi Guys,
I've configured a Cisco 3560 to do some routing for my subnets. I need to add some QOS for SIP.
We have a 25/25mbit internet connection. Do you need to see my config, or can you let me know what needs to be added?

My first question is will your SIP devices be marking traffic they send to the switch, and if so, do you want the switch to trust the markings they send. Second. Are you just trying to prioritize traffic at the WAN connection for SIP?

Ok, first, I have a Cisco UC520 behind the Cisco 3560. I'm open for advice here. I will go along with what you suggest. I am assuming this would be a good thing to do?
Secondly, I believe so, unless there is a better way of doing it. Basically, the pipe gets full. Without QOS, we get crackling etc on the SIP lines.
Cheers.

Just thinking about it, we would probably have to do this on the two vlans I have as well as the WAN, if that makes sense.
Okay. I will chime in tomorrow morning. Bedtime.
Okay, what do you have connected to the UC520 and on the 3560. Also, any reason you have it behind the 3560 instead of vice versa? Not suggesting yet, just prodding.
Man I wish EE had an edit button. When you say you need QOS on the vlan interfaces, are you experience degraded call quality from calls locally on the LAN, or just calls traversing your WAN connection.

I'm just trying to protect myself from SIP drop outs etc.
The 3560 is the main 'router'. It's routing a bunch of subnets for me. The UC520 is behind this. Reason for this is that there are two companies in this office, so the 3560 splits them. The UC520 is my network. So the UC520 is sitting on VLAN50 on the 3560. The only other devices connected to the 3560 is another router for another network on VLAN51.

Can you post the config for the switch? So both companies share the same wan connection? So Your uc520 and the other company's router default route to the 25Meg Wan connection?

So the wan just has a header IP. The subnets are split.
VLAN50 has a /29 public ips
VLAN51 has a /28 public ips
Each router plugs in to a port that's configured with public IPs. If that makes sense.
I won't be able to post the config for about 3-4hrs.
