I am having a problem with QoS on the 3850 platform. It seems no matter what I do I cant get the switch to properly mark traffic. Basically, I have VPN users that use jabber for phone calls. I have successfully configured QoS on 2960x and 3750x switc...

We recently started having issues with some VPN users where they are not able to RDP to a server when connected to VPN. They are able to ping the server, but not RDP to it. At random sometimes these users will have RDP access after connecting to the ...

Recently I have been trying to improve our QoS policies to improve the quality of voice calls. I finally created a SPAN port to our SIP router and started capturing some packets. I discovered that out Jabber client voice traffic is not being tagged w...

I recently update the SSL config of my ASA that is configured for VPN. We are using SSL VPN with AnyConnect version 4.4. If I updated the ciphers with the below configuration, AnyConnect will no longer work: ssl cipher tlsv1.2 custom "ECDHE-ECDSA-AES...

Just FYI, the destination port range was different due to the traffic being sent to our AQM server. Standard Jabber traffic looks to be the standard port ranges, source audio 16384-24574 and destination 24575-32767 ranges. According to Cisco TAC, the...

I have made those changes for testing, I just set it to a lower DSCP marking. But I still wasnt seeing that traffic get remarked. So it seems to be something with the switch. Not sure what it may be. I am also doing the capture from the 3850, but I w...

The other strange thing is that I can see the packets match on the policy, but nothing gets marked appropriately. In this example I have it on the SVI, but I have also tried it on the physical interface with no difference. Switch#sh policy-map interf...

Thank you for your reply. That is how auto-qos configures the ACL. But my packet captures show that only the source UDP ports are within the range of 16384 32767. That is actually a detail that hindered me getting it working on the 2960x and 3750x sw...
