Hello all,

I've been trying to setup a lab CME 4.1 environment. The CME router is a 3745 with IOS advipservices 12.4-15-T8. I'm using a 3524XL-PWR for the phones. I have 3 7970G's that I'm trying to use with this. I setup interface fa0/0 on the router with 2 subinterfaces, fa0/0.10 and fa0/0.20. Dot1q encapsulation. I have also setup the ruter as an NTP server, as well as TFTP server. The relevant config is:

no ip dhcp use vrf connected
ip dhcp excluded-address 192.168.11.1 192.168.11.10
ip dhcp excluded-address 192.168.11.245 192.168.11.254

The problem is that when I plug in the 7970 to the switch it powers up just fine, but never registers to the CME router. I'm not sure what I'm missing/doing wrong. I'm trying to get the IP Phones on a voice vlan and use the switchports on the phones for PCs connected that will be on data vlan 20. If anyone has any suggestions please share, and thanks for the advice.
 
Yeah
The 3524's can be a bit klunky in their configuration and I also had the same problem. Try;

int fastethernet <mod>/<port>
switchport mode trunk
switchport encap dot1q
switchport trunk native vlan 20
switchport voice vlan 10
no spanning-tree
exit

This is what worked for me.

The CCNA-Voice book assumes everybody has access to the latest and greatest hardware, but for those of us on a budget....
The upside is you learn more getting legacy hardware to work.
