I have implented WAAS between sites over our WAN and I am also implementing QOS. I am looking for advice on a situation I am having with policing NetApp traffic where WAAS is implemented.
In source site "A" I have some NetApps off an LAN interface and on that LAN interface I am policing that NetApp traffic to 30Mb as destination site B that I am sending that NetApp data to is a DS-3 and I want to leave 15Mb of room for other traffic.
I have implemented WAAS off of seperate interfaces off of each router using WCCP.
The WAAS is compressing this traffic by 40-60% of the original size, with the other WAAS optimizations I am seeing anywhere from 10-20Mb of NetApp traffic hit remote sides serial interface.
I could adjust the police rate on the Source site "A" LAN interface by adding another 10Mb but in a situation where that traffic might not be optimized optimally I could saturate destination site "B" serial interface.
I thought about using EEM to script out something where the router at Site A could login to router at Site B to take bandwidth measuremetns on Site B and then adjust it's own police rate, but don't know if that is the best way or would over-complicate things.
Thanks in advance.
