mandatory
Each entry configures a range of host IP addresses to be
associated with a given interface ( port ). If the range
consists of a single host address the entry may optionally
specify a physical address. The entry is indexed by the range
and the port. Ranges may not overlap. However a range may be
duplicated on different ports.
The address range must lie within the subnet defined for a
given workgroup and thus the entry acquires the security
level of that workgroup. If security is violated, packets
to and from a given host IP address will be filtered out
passing through the router. The source and destination IP
packet addresses are checked against ranges in the range table
during packet forwarding and must match as follows:
For a high (4) security workgroup, a host must match a single
host range entry - it must reside on the port with the
physical address as configured in that entry.
For a medium (3) security workgroup, a host must match a range
entry in that it resides on that port, but unless a physical
address is also specified in that entry, the physical address
is not constrained.
For a low (2) security workgroup, a host is free to reside on
any port with any physical address as long as its IP address
does not lie within the range of any entry in the range table,
but if it does fall in a range then it must completely match
that entry, or another entry with the duplicate range. Match
completely means match the port and, if a physical address
is specified, match that as well.
