Hi, The default value of "if_up_cmd" is: /usr/bin/sudo /sbin/ip addr add $_IP_$/24 dev eth0 label eth0:0 If the network interface "eth0" exists on Pgpool-II servers, the command may run successfully. I think the default value of "if_up_cmd" was executed to bring up the VIP. > Hello everyone. > > We have a pgpool & postgres setup made as per the given example > <https://www.pgpool.net/docs/latest/en/html/example-cluster.html> > > We haven't configured the *if_up_cmd, if_down_cmd & **arping_cmd* in > pgpool.conf > (we commented it out on purpose).
