class=410054915-12102009>You are not going to get 8 Mbps on your day2day
class. First off, you give 3% priority to voice, which leaves 97Mbps
remaining. The next class in your policy-map (DR) is saying to
use 89% of the <EM>remaining</EM> 97Mbps (84.39Mbps), and finally you have
day2day traffic can have 8% of the <EM>remaining</EM> BW. So your DR
replication I assume will be using a good bit of bandwidth all day long, so you
are only going to get 157Kbps for DR traffic (if DR and Voice are using 100% of
what they can get), because the "remaining" keyword tells the IOS to allocate
that percentage of bandwidth that has <EM>not</EM> been allocated to other
classes. I would do this:</SPAN></FONT></DIV>

<DIV>Hello my Pundits</DIV>
<DIV><SPAN><FONT face=Arial></FONT></SPAN> </DIV>
<DIV><SPAN><FONT face=Arial>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%.... </FONT></SPAN></DIV>
