Static IP Configuration issue

Goodmorning,

I'm trying to set a static IP to eth1 port, setting this configuration inside the "/etc/dhcpcd.conf" file:

# Static IP configuration of eth1:
interface eth1
static ip_address=192.168.254.20/24
#static ip6_address=fd51:42f8:caae:d92e::ff/64
#static routers=192.168.254.1
#static domain_name_servers=8.8.8.8

However, after the device reboot, launching the "ifconfig" command, I have this result:

eth1: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether c8:3e:a7:01:37:f5 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

It seems that the IP configuration is disappeared.

Have you ever found this kind of problem? Am I doing something wrong in the process? Can you give me any advice?

Thanks.

Luigi

Use "ip addr show" instead.

ifconfig doesn't show all information anymore and is considered deprecated.

Thank you for the advice, I tried with "ip addr show" command, but the result seems the same:

3: eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
link/ether c8:3e:a7:01:37:f5 brd ff:ff:ff:ff:ff:ff

Eth1 IP configuration seems disappeared, but I cannot understand why considering also the static IP configuration done.

It seems that the pysical Ethernet link is not established (NO-CARRIER). Please check your wiring and the LEDs of the Ethernet connection.
