The Group IP netmask comes from the physical interfaces.  It doesn't have one on its own.   When changing the netmask make sure that established initiators aren't going to be excluded by the new netmask. 
Hello All, is there a possibility to change the Netmask of an EQL after it has been set up? In the GUI i have only found that place where to change the Group IP and the Place where I can Manage the IP and Netmasks of the Interaces. Same for the CLI. Is the Netmask of the Group IP just the same as the one of the Interfaces, as long as they aren't reserved for Management? thanks in advance.  best  regards  Mathias
