Hi Everyone,
I’ve been struggling with getting QoS to work on an RV180W router. My goal is to prioritize outbound RDP traffic over everything else. Here is what I’ve done in the configuration:
Create a custom service: RDP (TCP 3389)
Enable WAN QoS under Global Settings
Configure as Priority
Set High Priority to 95%
Set Total WAN Internet Bandwidth to 5Mbps (to match my actual upload capacity)
Add a WAN QoS Profile “High_Priority” and set its priority to “High” (which should be 95%)
Create a profile binding:
Select “High_Priority” for WAS QoS Profile
Select RDP as the Service
Traffic Selector Match Type to IP Address
Starting IP Address: 192.168.1.2
Ending IP Address: 192.168.1.254
With this configuration, I would expect that I could guarantee 95% of my 5Mbps bandwidth to transmit data over the RDP service. 95% of 5Mbps is 4.75Mbps, or roughly 608KBps.
When I connect to an RDP computer and begin uploading a file over RDP (via drive mapping), I can see that I’m getting roughly 600KBps consistently. When I begin uploading a large file to an FTP server, the RDP traffic drops to about half and the FTP traffic is consistent at about 300KBps. I would expect the RDP traffic to remain at roughly 550-600KBps or so, but it is not even close. If I disable the QoS, there is no change at all.
I’ve spoken with Cisco tech support and they were not able to fix the problem. I was told that the router will use QoS on as-needed basis, but in this case, it clearly is not. I’ve also tried using the rate limit settings which seem to be completely ignored. Is this a firmware issue or a limitation of the router? Am I configuring the QoS incorrectly?
Cheers,
Greg
