How to expand a netmask in a Network interfoce for my SBC acme packet and if it is needed to reboot

Hi team,

i have the necesity to expand one of my network interface of my acme packet sbc in order to have more host IPs available for service cofniguration, fortunatly i have the option to expand the netmask since the next subnet is available in my network.

So, I would need to change the netmask in my sbc for one of the interfaces, so hope to receive your suggentios and reommendations for doing this change,

Considering to have a SBC Acme Packet Net-Net 4500 SCZ7.3.0 MR-2 Patch 2 (Build 424)  in High Availabity mode and only one network interface need to be modified
