3.nmcli c mod -h

[root@cloud ~]# nmcli c mod -h
Usage: nmcli connection modify { ARGUMENTS | help }

ARGUMENTS := [id | uuid | path] <ID> ([+|-]<setting>.<property> <value>)+

Modify one or more properties of the connection profile.
The profile is identified by its name, UUID or D-Bus path. For multi-valued
properties you can use optional '+' or '-' prefix to the property name.
The '+' sign allows appending items instead of overwriting the whole value.
The '-' sign allows removing selected items instead of the whole value.

Examples:
nmcli con mod home-wifi wifi.ssid rakosnicek
nmcli con mod em1-1 ipv4.method manual ipv4.addr "192.168.1.2/24, 10.10.1.5/8"
nmcli con mod em1-1 +ipv4.dns 8.8.4.4
nmcli con mod em1-1 -ipv4.dns 1
nmcli con mod em1-1 -ipv6.addr "abbe::cafe/56"
nmcli con mod bond0 +bond.options mii=500
nmcli con mod bond0 -bond.options downdelay

4.示例(添加网卡及参数)

[root@cloud ~]# nmcli c add con-name ens160 type ethernet autoconnect yes ifname ens160 ip4 10.1.1.170/24 ipv4.dns "210.21.196.6 202.96.128.86" gw4 10.1.1.254
