7 Forwarding
SIGNAMAX 065-7909HPOE industrial switch has unicast MAC address forwarding and
multicast MAC address forwarding, the introduction is followed.
7.1 Unicast MAC Address
MAC address forwarding table: the device forwards the packets to the corresponding port
according to the packet destination MAC address. The MAC address forwarding table reflects
the relationship between the MAC address and the forwarding port.
A MAC address table is maintained for packet forwarding. Each entry in this table indicates
the following information:
 The MAC address of a connected network device
 The interface to which the device is connected
 The VLAN to which the interface belongs
Unicast MAC address configuration is for the unicast forwarding mode.
7.1.1 MAC Address
On this page, you can add an entry in MAC table.
VID：Specifies a VLAN group with which the MAC address corresponds.
Unicast MAC Address： Specifies the destination MAC address.
Port：Specifies the port of the outbound interface.
Type：Choose among Dynamic, Static and Blackhole.
 Static MAC address entry: Also known as permanent MAC address entry. This type
of MAC address entries are added/removed manually and cannot age out by themselves.
Using static MAC address entries can reduce broadcast packets remarkably and are
suitable for networks where network devices seldom change.
 Dynamic MAC address entry: This type of MAC address entries age out after the
configured aging time. They are generated by the MAC address learning mechanism or
configured manually.
 Blackhole MAC address entry: This type of MAC address entries are configured manually.
A switch discards the packets destined for or originated from the MAC addresses
contained in blackhole MAC address entries.
The lower part lists all existing unicast MAC addresses, as well as the information of each
unicast MAC address. The user can also modify or delete an existing unicast MAC address.
Dynamic MAC address will also be shown on the Dynamic MAC Address page.
