- When I add the arp entries in /etc/ethers, it can be persistent after reboot, but when I use nmcli to down/up the NIC, the entry will disappear in arp table.
# cat /etc/ethers 192.168.10.1 00:1a:4a:16:01:84 # arp -v Address HWtype HWaddress Flags Mask Iface 192.168.10.1 ether 00:50:56:9e:02:0e CM ens192 Entries: 1 Skipped: 0 Found: 1 # nmcli con up ens192 Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/3) # arp -v Address HWtype HWaddress Flags Mask Iface Entries: 0 Skipped: 0 Found: 0
- How to let the arp entries added by manual be persistent when I up/down NIC by nmcli?
