Notice:
If no DHCP server is present in the network, the DHCP client fails to get IP
conguration information, the switch then restores the IP parameters to default
in several minutes to ensure a valid IP address being equipped.
4.3.2 Aging Time and Dynamic Address Table
A dynamic MAC address table is maintained inside the switch. A MAC address
is the physical address of a network device; it is six-bytes long and should be
hole in a subnet. A network device can be identied by its MAC address.
A dynamic address table entry contains two items: MAC address and its
corresponding switch port. The dynamic address table is volatile. The dynamic
address entry begins to age once it has been added; it will be purged if it isn’t
renewed in a specied length of time, which is dened as aging time.
The aging time ranges from 0 to 3825 seconds for this switch family.
The default value is 300 seconds. Dynamic address table entry won’t age if 0
is set. The aging time precision is 15 seconds.
4.3.3 Static MAC Address Table
A static MAC address table entry contains a MAC address and its
corresponding switch port. All the packets taking that MAC address as their
destination will be forwarded to the corresponding switch port.
The static MAC address won’t age, which differs from the dynamic MAC
address. The static MAC address table entry is always valid before it is
deleted.
