2940 connected to 2950 with VLANS

Hi

In my office, i have an 2940, no config. I want it to connect to the access sw, which again is connected to the dist/core. My port in the access sw have this config:

interface FastEthernet0/8

switchport access vlan 99

switchport mode access

switchport voice vlan 20

no ip address

spanning-tree portfast

When i connect the 2940 to this 0/8 port, only some traffice seems to pass. I have several IP phones in my office, but only two would register. The pc is connected via IP phone, but then, only the pc get's access, not that IP phone. I find this strange, about how i should configure the 0/8 port in the 2940, so that all the traffice from the access sw gets through to all my 2940 ports.

regards

/alf

Re: 2940 connected to 2950 with VLANS

If you configure port fa0/8 to be member of vlan 99 and voice vlan 20 you can only connect a IP phone to that port with built-in switchport that connects the PC/notebook.

You should not connect a switch to that port. If you want a to connect that switch you can use a trunk to transport VLANs. Furthermore portfast is ONLY to be used on edge ports.
