If the mask bit of that port(s) is specified by being set up as 1, when there is a link loss
occurring on that port(s), relay output will be activated. The mask value is in hexadecimal
format that represents the 8 bits corresponding binary numbers, it can be either in the form
of initiating “0X” plus a suffix of the hexadecimal number or eliminating “0X”; simply the
hexadecimal number itself. If a mask value is not specified, the “lmask” command will
display previous assigned mask value.
