Point-to-point IP addresses
Note: The example point-to-point addresses use a 31-bit mask to save address space. This is optional and
covered in RFC 3021. Below is an example when setting an IP address with a 31-bit mask on a Dell EMC
S4048-ON. The warning message can be safely ignored on point-to-point interfaces.
S4048-Leaf-1(conf-if-fo-1/49)#ip address 192.168.1.1/31
% Warning: Use /31 mask on non point-to-point interface cautiously.
