3.6 Macf Command (Addresses Mapping)
The command is used to map IP-addresses onto Ethernet MAC-addresses
Syntax:
macf MAC-address IP-address Comment
macf del N
macf [-]dhcp [-]strict | [-]reverse | [-]simple [-]quiet
macf show | clear
Description:
The macf command performs static mapping of IP-addresses to MAC-addresses in
an Ethernet network. It may be useful for service providers when they connect to
their network a group of clients (such as individual users in an apartment block)
via one common access unit. In this case, clients may be tempted to change their
IP-address to that of a neighbor, thus deceiving provider's accounting system.
Although it is almost impossible to definitely resolve this issue, you can make
however your life easier by directly mapping the client's assigned IP-address to
his/her MAC-address, because surreptitiously modifying a MAC-address is much
more difficult for an average user.
Every macf MAC-address IP-address command adds a new address pair to the
address mapping table:
macf 102030405060 1.1.1.1 Room123
macf 203040506070 2.2.2.2 Room125
The comment parameter is a simple description string with no syntax restrictions.
The current state of the mapping table may be displayed by a macf show or co
show command:
macf show
The output is the following:
macf 1 0020af915099 192.78.64.99 Server
macf 2 0020af9150a3 192.78.64.194 Room94
macf 3 0020af9150a4 192.78.64.134 Room57
macf 4 0020af9150a7 192.78.64.174 Admin
