Hi,

The case gives me hints towards the configuration register value which is not set to proper value, so the switch is not checking the the saved configuration in the config file.

Please do the below steps.
1. Log into the switch
2. Come to enable prompt
3. Typein the below commands
config t
config-register 0x2142
end
write memory

The find an example of the prompt and the commands below

Switch# config t
Enter configuration commands, one per line. End with CNTRL/Z.
Switch(config)#config-register 0x2142
Switch(config)#end
Switch#write memory


After this you can configure your switch as per your requirement and then save the config by typing write memory

Now you can reboot your switch and the switch will come up with the configuration as you set.

Best Regards

Cisco 7942 factory reset


When performing the factory reset procedure we are about to describe, it is important to keep in mind that the IP phone will lose all configuration files and phone applications. This means that it is necessary to have CallManager or CallManager Express setup so that the IP phone will be able to receive the new information (phone application and configuration) after the reset procedure is complete, otherwise it is most likely that the IP phone will not be usable until this information is loaded on to it.
This preparation also happens to be the procedure for upgrading a Cisco IP phone firmware.



Follow the steps below to successfully factory reset your Cisco 7942, 7962 IP phone:
  1. Unplug the power cable from the phone and then plug it back in. The phone begins its power up cycle.
  2. While the phone is powering up, and before the Speaker button flashes on and off, press and hold #. Continue to hold # until each line button flashes on and off in sequence in amber.
  3. Release # and press 123456789*0#.
You can press a key twice in a row, but if you press the keys out of sequence, the factory reset will not take place.
After you press these keys, the line buttons on the phone flash red and the phone goes through the factory reset process.
Do not power down the phone until it completes the factory reset process and the main screen appears.

Why lose a router settings after a power outage?


Question:<br> After a power outage <a href="http://www.3anetwork.com/cisco-1900-series-routers-price_c12"><b>Cisco 1900</b></a> lost my router configuration, was saved, reload the configuration, save, reboot and no problem.<br> How to know if my router is properly, all my services run smoothly? Why it happens that configuration is lost?<br> Are there any benefits the settings saved in flash?<br> Answer:<br> Did you check if the NVRAM was empty or running config was empty?<br> If router booted with empty running config, it could be that startup got erased (NVRAM issue) or that it did not load it from startup to running (likely config-reg) issue.<br> Since in your case config-register ix 0x2102 and was not changed, the problem should be with NVRAM.<br> From me exprience, I have seen that in the following cases:<br> - config was not saved to NVRAM;<br> - at the time of powerdown the NVRAM startup file was accessed for editing (e.g. saving running config) and got corrupted or erased;<br> - NVRAM HW issues cause file system problems.<br> Is it reproducible in your case? E.g. if you powercycle the switch, do you see the same problem with config loss? If yes, check the NVRAM content. <a href="http://www.3anetwork.com/cisco-1900-series-routers-price_c12"> <b>Cisco 1900 router</b></a> That could give some hints.

My Cisco IP Phone 7945G keeps rebooting after I did a factory reset. Is there a way to fix this?


According to Cisco, when initiating a factory reset procedure certain information from the IP phone is erased while other information is reset to the factory default value, as shown in the list below:


Information Erased:
  • CTL File (Certificate Trust List)
  • LSC File (Locally Significant Certificate)
  • IP Phone Call History (Calls Received, Placed, Missed etc)
  • Phone application
Information Reset to Default:
  • User configuration settings (ring tone, screen brightness, sound levels etc)
  • Network configuration settings

t is highly advisable to follow the firmware upgrade procedure in a non-working environment to ensure other phones are not affected (in case of an accidental reboot), and to avoid the freshly factory reset ip phones obtaining the working environment's settings.


Please use the link below and follow the instruction http://www.firewall.cx/downloads/cisco-tools-a-applications/cisco-ip-phone-a-ata-firmware-downloads.html

Cisco Unified Communications 500 Series reset password with out losing my configuration


Hello,
if you are talking about your enable password you will have 2 choices which are a factory reset or evoke ROMMON. The simplest way is to backup your running config via TFTP or do a #show run and copy and paste the whole config to a txt file and then reset to factory default and then just load(or paste) that config and then do a #copy run start.

try to update the Firmware of the router. You can do this by opening the Cisco Connect Software under all programs. It should ask for an update when it initializes, if not then power cycle your network.
