I have a Cisco 6509e core switch running multiple VLANs. The two VLANs I am concerned with are for the voice and employee data networks. Recently, there was a fiber circuit installed to provide connectivity to the switch between floors due to an upcoming move. Rather than ordering Cisco equipment for the new area, HP Procurve switches were purchased. I have put the Fiber circuit into trunk mode on the 6509e and the Voice Procurve. I then selected an Ethernet port to use to trunk between the switches downstairs. I was expecting all VLANs to be carried through the trunks, but this is not what occured. I can get a voice connection when the fiber is connected to the voice switch and a data connection when I connect directly to the data switch. Does anyone know what configuration needs to be done to make this set up work properly?
