Introduction To Mac Binding - UTStarcom iSpirit 3026 Manual

9.1 Introduction to MAC binding

MAC binding ensures that users can be safely connected into Internet through switch. Special
MAC Add. is legal if some ports of switch is bound with special MAC Add, and switch allow these
legal MAC Add. users to connect to Internet through the port, but does not allow illegal MAC Add.
users to connect to the Internet, so users' safe connection is ensured.
Switch will always check the data flow input from the port binding with MAC Add. the data flow is
allowed to be forwarded if source MAC Add. of data flow is bound with legal MAC Add., but the
data flow will be thrown away if illegal MAC Add.is bound with. To prevent illegal users connect
to the Internet via throw away data.
IEEE802.1Q standard supports two kinds of MAC Add. study modes (SVL and IVL). SVL means
that MAC and VLAN are separate, MAC Add. in all VLAN must be only one, disregard VLAN
when study MAC Add. IVL means that MAC is related with VLAN, MAC Add. can be the same in
different VLAN, but in the same VLAN MAC should be only one, MAC Add. belongs which VLAN
must be known when study MAC Add. iSpirit 3026 switch supports IVL mode, but MAC Add.
belongs which VLAN must be specified when do MAC binding.
