ip public on fastethernet L2

[davidegiordano991]

Good morning,

How do it configure an ip public on an interface fastethernet on router cisco 800 series?

the error  is "iP addresses may not be configured on L2 links"

Thanks

Configure vlan interface.

hi davide,

paolo is correct. kindly assign this on a VLAN interface (SVI).

syntax would be like:

interface vlan x

ip address
