Re: Address determined by ???


When the output indicates NVRAM it is indicating that the interface address configuration was previously configured, saved to NVRAM, and was read from NVRAM at bootup. When it indicates manual it is indicating that you have manually configured this interface since the last time that the router booted.

If you really want to change it, save the config to NVRAM (startup-config) and reboot the router. I do not believe that it will change anything that impacts what you are doing or any problem that you may be experiencing.
