I set up a lab and used to be working fine till yesterday. The problem is the all the phones (7961 & 7960) in one VLans can not be registered on the Call Manager, but the phones in other vlans are working fine. For the phones that can not register themselves on the call manager, they still can get ip address from the PUB,which is my DHCP server. for the PUB and SUB, Auto-regiter has been enabled and tftp on both servers is running as well. on the screen, I can see the phone are requesting the SEPMACadress.cnf.xm file, and on CUCM, the phones shown regitered.... Can anyone give me any hints about it? Thanks
Enable Detail level tracing on the TFTP process. Use RTMT to review the trace file to see what (if anything) is happening with the TFTP server. Detail level should allow you to see client connections and requests to retrieve files.
Use a TFTP client to retrieve a file from the CUCM TFTP server (just to be sure that is working). You are in a lab environment, so put your PC/Mac/etc. in the voice VLAN and test that if it seems appropriate
