[cisco-voip] Need Help Configuring Cat2924XL

[Lelio Fulgenzi]

My first guess would be to turn trunking on those ports. You have configured voice vlans, not data vlans, so it needs to be set to trunk in order to enable those to work. I've tested with my phone, and not having the trunk statement breaks things pretty quick. It doesn't even try to get an IP address off the data vlan that I've set.

Here's a snippet:

interface FastEthernet0/24
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 25
 switchport mode trunk
 switchport voice vlan 625
 spanning-tree portfast
end

  I've got a Cat2924XL with the following relevant config snippets:

  rwc-2924xl-131#show vlan
  12   DMZ                              active
  100  IP Phones                        active    Fa0/7

  interface FastEthernet0/5
    switchport voice vlan 100
    spanning-tree portfast
  !
  interface FastEthernet0/6
    switchport access vlan 2
    switchport voice vlan 100
  !
  interface FastEthernet0/7
    switchport access vlan 100
    spanning-tree portfast

  interface FastEthernet0/24
    switchport trunk encapsulation dot1q
    switchport mode trunk

  interface VLAN2
    ip address 172.16.0.131 255.255.0.0
    no ip directed-broadcast
    no ip route-cache


  So...  FE0/7 works fine (as you would expect), but neither 0/5 or 0/6 
  work ...  The phone sees the operational VLAN 100, but never gets an 
  IP..  What the heck am I doing wrong?  Cisco's docs only show the 
  "switchport voice vlan" option as being relevant.  Is there something 
  I'm missing on the switch config?  I've rebooted the phones and switch a 
  few times.

  Thanks for any help,
