l MAC filtering function: When the switch receives the packets with specified source
address or destination address, it drops them according to source MAC address and
destination MAC address.
l
MAC address learning control means MAC learning can provide three types of learn-
ing modes including hardware wire-speed learning, CPU controlled learning and non
learning to satisfy various user requirements. In addition, MAC learning can provide
global, port-based, TRUNK-based and VLAN-based independent switches.
l
MAC learning number limit can configure the maximum learning MAC address number
based on global, port, TRUNK and VLAN. When the value is reached, the new MAC
cannot be learnt.
l MAC alarm control can configure the output of the common alarm information of MAC
function, for example, the MAC learning number limit is exceeded and address drift.
l
MAC address fixed function can transform the dynamic MAC entry to static or fixed
MAC entry in batch. After transformation, static entry cannot drift. When the device
is rebooted, MAC fixed entry can recover and cannot disappear.
l
MAC information display means the current MAC function configuration and state
information can be checked.
Note:
The MAC address of Ethernet NIC is a group of 48–bit number. The 48 bits include two
parts. The previous 24 bits are used to represent the manufacturer indicating Ethernet
NIC. The following 24 bits are a group of sequence numbers designated by manufacturer
and named as OUI (Organizationally Unique Identifier). The lowest bit ( the most left bit in
the structure) is named as private or group bit. If this bit is set to 0, the rest address is a
private address. If 1, it means the remaining address domain identifies the group address
requiring more resolution. If the whole OUI is set to 1, each site of the whole network is
destination. That is the special engagement supported by OUI.
Configuring an MAC Table
The MAC table configuration includes the following commands:
Command
zte(cfg)#set port <portlist> security {enable | disable}
zte(cfg)#set port <portlist> multicast-filter {enable | disable}
zte(cfg)#set port <trunklist> multicast-filter {enable | disable}
zte(cfg)#set mac add static <HH.HH.HH.HH.HH.HH> port <1-28>
vlan <1-4094>
