Cisco Jabber/APM/Cannot Make Internal Calls
Have a request from our customer to implement VOIP on their SSL VPN - have configured everything on the F5 based on the KB article found here. User can make all of the external global calls they wish, however users cannot speak to each other using voice internally. Has anyone encountered this issue - did I miss something from the KB article?
Configuring QoS for priority queueing and bandwidth reservation
Hi folks, can someone explain how to set up QoS on a BIG-IP to get priority queueing and bandwidth reservation working for packets that are already QoS tagged (L2 CoS, L3 DSCP)? The scenario is the following: Network packets will be marked by the endpoints (or other devices) on Layer 2 (CoS) and Layer 3 (DSCP) according to the following scheme: That being said the packets that enter the BIG-IP already carry their QoS tags. The BIG-IP shall do two things with the packets: The QoS tags must not be changed and remain their original values For every application/traffic class the BIG-IP shall reserve a specific bandwith and assign a priority queue according to the QoS class On the switches and routers the following QoS polices have been implemented which ideally should be the same for the BIG-IP: For the first point (leaving the QoS tags unchanged) I think the solution is to configure the UDP/TCP profiles with IP ToS/Link QoS: Pass Through But how do I accomplish the second point (bandwidth reservation and priority queueing)? In the Network tab I found Class of Service and Rate Shaping, in the Acceleration tab there is Bandwidth Controllers. Which feature is the right one and how does it need to be configured for this scenario? Thx a lot!
