It doesn’t look like ‘ip link’ has the syntax to remove an alias, but it can be
done via sysfs:
# ip link show dev lo
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode
DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
# ip link set dev lo alias loopback
# ip link show dev lo
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode
DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
alias loopback
# echo > /sys/class/net/lo/ifalias
# ip link show dev lo
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode
DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
It also can be set there too:
# echo hicentos > /sys/class/net/lo/ifalias
# ip link show dev lo
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode
DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
alias hicentos
