Cisco IOS 124-15

[oldbag]

Hi,

I have a CISCO 857 (running the 124-15.T5 IOS) and get an "Invalid input detected" as the following is present in the config: "no ip dhcp use vrf connected". This command gets added automatically when you define you wish to use DHCP within the config.

If I run "ip dhcp use" on the command line "vrf" isn't an option. I just have 'class'.

Do I need to worry about this error? DHCP seems to work OK.

I've tried rolling back to older IOS's and no joy, and also I receive more "Invalid input detected" on other config lines...

It's nothing to worry about so you can safely ignore it.

I assume you mean it gets added when you configure the unit via the web interface?

It'll most likely just be a slight incompatibility between the web interface and the router's feature set, the former setting a feature which the installed IOS image doesn't support.
