Hi,
I am configuring a (powerconnect 3548P) switch for both data and voice, with VLAN1 for data (untagged) and VLAN100 for voice (tagged). Both the PC and IP phone are picking up the right IP addresses, but I am stuck on the configuring of QoS.
I am trying to set the QoS trust as DSCP both from a command line and the GUI but is returns an error of "Voice VLAN and advanced mode/no qos/trust dscp configuration prevention'.
I know it must be something simple but it's doing my head in as I cannot see what I'm doing wrong.
Any help would be much appreciated.
