Specifies the required 1–8 character identifier of the network containing the host.
Note: The use of the national character, #, is discouraged,
because this character might not be present on keyboards of terminals
produced in some countries. Because # might not be available on all
terminals, SNA architecture specifically excludes # from the list
of valid characters that can be used for defining network names (NETIDs).
Although VTAM® allows you to
use #, other products might enforce this restriction.
NETID should be unique to each network within a set of SNA interconnected networks. Within each network, each SSCP must have the same NETID. Besides NETID, a gateway configuration requires GWSSCP=YES and an SSCPNAME.
