dhcpcd not giving a static lease

I'm getting a new computer set up on my network, and although I have set up dhcpcd to set a static lease with a particular IP address, the same way I've previously done it, and seemingly following the docs, I am being given a DHCP lease instead.

I'm using eth0 for my interface (using the "Revert to traditional interface names" section of the Network Configuration docs). I've added to /etc/dhcpcd.conf:

#define static profile
profile static_eth0
static ip_address=10.10.1.50/24
static routers=10.10.1.1
static domain_name_servers=10.10.1.1

# fallback
interface eth0
fallback static_eth0

where 10.10.1.1 is the correct address of my router and DNS server.

I've removed the leases in /var/lib/dhcpcd/, run "dhcpcd -k", and run "dhcpcd", which reports that it is "soliciting a DHCP lease", which the router duly gives, leaving me connected to the network on 10.10.0.220. What am I doing wrong?

Re: dhcpcd not giving a static lease

You are setting the static profile as the fallback, so it will be only used if dhcp fails.

Re: dhcpcd not giving a static lease

Huh. I had the fallback line previously, and it worked as expected. But removing it, and changing it to "interface eth0", did in fact do the trick.

Thank you.
