Should work fine.

If you forgot to put "no switchport" on, you'd get an invalid command
response.
If you had a different mask/overlap on a different port, you'd get
"163.1.0.1 overlaps with (other intf)"

Otherwise, that works. If you were accidently typing in "ip address
163.1.0.0 255.255.255.128" though, you would get that error.
