Cisco Telepresence System - Error removing CTL file from codec GUI
When changing from secure to non secure, rarely the codec will not delete the CTL file via GUI (Unified CM)
Error deleting the CTL file via GUI (Unified CM)
Example from Sysop logs:
2012-02-23 20:41:57: ERROR Download unsuccessful: File CTLFile.tlv not found on host 184.108.40.206
2012-02-23 20:41:57: INFO Using existing CTL
Unfortunately, the only way to recover is to factory reset the codec to remove the CTL file.
Suggested steps to recover via CLI SSH access to the codec:
NOTE: Physical access to the codec is necessary via a laptop connected to the doccam port with the laptop set to DHCP and the wireless adapater disabled.
admin: utils system factory reset init
init - This will set the system to the factory initialized configuration but leave the system on its current boot slot (Suggested option), or
reset - This will set the system to the factory default setting including setting the boot slot back to the factory slot
NOTE: This can take anywwhere from 15-30 min to complete. PLEASE do NOT power cycle until it completes the reset !! Reset progress can be monitored with a browser opened to the IP of the codec (IP for the laptop of 10.0.0.2 and for the codec through the doccam port 10.0.0.1 to access).
2. Once reset is complete, type "admin: show config system" and verify model type
3. If incorrect model type appeasrs (e.g. showing CTS 1000 when it should be CTS 1300) correct as follows:
