Issue

From the WebGUI, under Network > Interfaces > Ethernet, the DHCP enabled interface gets the /32 IP address regardless of the mask configured on the DHCP server. In the following diagram, ethernet 1/3 is acting as a DHCP client:

As shown below, the DHCP server is configured with /24 mask, still the interface gets the IP address in the /32 range:

Resolution

When the interface gets the IP from the DHCP, it shows the mask as /32, regardless of the actual mask. The only way to view the actual mask is to use the following CLI command:

>  show routing route

The command installs the correct subnet.

 

The following diagram shows the right subnet installed in the routing table, which is /24:
