Subnet masks can be written as hexadecimal numbers or as decimal IP addresses.
There are three methods for making sure the terminal can discover the subnet mask:
(Setup -> Change Setup Parameters -> Booting [TCP/IP Boot Options section] -> Send Broadcast ICMP for Subnet Mask).
Table 3-3 boot-send-broadcast-icmp-for-subnet-mask Parameter
Setting the Subnet Mask in NVRAM
Use the ip-subnet-mask parameter to set the subnet mask explicitly (Setup -> Change Setup Parameters -> IP -> Subnet Mask). This parameter takes effect immediately and is saved in NVRAM.
