[cisco-voip] QoS for Day to Day traffic

[Lelio Fulgenzi]

Will there be regular data, like FTP, web, etc coming from PCs contending with that phone ip traffic though? I would put it all together in the voice class. Last thing you need is someone trying to FTP a DVD ISO and causing your phones to somehow loose connectivity. Likely won't happen, but just in case.

The DHCP, RTCP, TFTP traffic can all be lumped into the Day2Day class, as that 8 Megs should be reserved. 
That is traffic that is NOT part of the 10.31.0.0 subnet. The remaining 89 Megs will then carry DR traffic only. 

Does that make sense?

I don't know your network, and my network hat has some dust on it, but according to your match statements, it looks like you're matching actual voice traffic only. Do the phones not also have traffic that is not marked as voice traffic such as DHCP, TFTP, signalling, etc? Isn't that reguarl IP traffic? 

Also, how many phones at the remote site? We have a remote site with a hundred meg link as well, and we asked to get the maximum number of calls reserved. We're not even close to utilization, but I imagine, if we were, we would go with a mechanism like yours where it's reserved but shared. 

Just some thoughts.

Hello my Pundits 

I have a 100Meg Ethernet WAN connection between two towns for DR purposes, and we are going to run "day to day" traffic (voice and data) over this circuit as well, now when replication and SAN to SAN traffic hits I don't want it to mess with the "day to day" traffic. The DR traffic will either source or destination to 10.31.0.0. So I made a couple of ACL's to match that IP to. The end result is I want to voice traffic to have priority and 3Megs of bandwidth, Day to Day traffic around 8 Megs of traffic and DR (San to San) the remaining 89%.... 

1. Do you think this will work? 
2. Do you think it is set up right?

access-list 101 permit ip any any
