Maintaining the Router

The “Do not check the version of the software” option is used 

for backward compatibility purpose during upgrade. Your 

upgrade attempt may fail even if you select the correct 

software version (the system prompts you with “invalid 

version” message at this time). If you are experiencing this, 

you can select this option to have the system skip version 

check during upgrade. This option, however, works only 

once; the system checks software version all the same at 

reboot.

the console port without building up another configuration 

environment.
