24-Port 10/100 + 4-Port Gigabit Switch with WebView and Power over Ethernet
Admin > Forwarding Database
Admin > Forwarding Database
Switches store the addresses for all known devices in a
forwarding database. This information is used to forward
traffic directly between the inbound and outbound ports.
All the addresses learned by monitoring traffic are stored
in the dynamic address table. You can also manually
configure static addresses that are bound to a specific
port.
Address Aging
Sets the aging time for entries in the forwarding database.
The aging time is used to age out dynamically learned
forwarding information.
Aging Status When enabled, dynamic MAC addresses
are discarded after the Aging Interval has expired.
Aging Interval (secs) (10-1000000) This is the amount
of time after which dynamic address table entries are
discarded.
Set the Aging Interval by entering the number of seconds
into the text field provided.
Click Save Settings to save the changes.
Static Address Setting
A static address can be assigned to a specific interface on
the Switch. Static addresses are bound to the assigned
interface and will not be moved. When a static address is
seen on another interface, the address will be ignored and
will not be written to the address table.
Static Address Counts The number of manually
configured addresses. The Switch allows 1000 Static
Address Counts.
Interface Port or LAG associated with the device assigned
a static address.
MAC Address (XX-XX-XX-XX-XX-XX) Physical address of
a device mapped to this interface.
VLAN ID of a configured VLAN (1-4094).
Specify the interface, the static MAC address, and VLAN,
then click Add. The current static addresses on the Switch
are all displayed in a list. To delete a static MAC address
from the forwarding database, select the entry in the
displayed list, then click Remove.
Dynamic Address Query
The Switch’s dynamic address table contains the MAC
addresses learned by monitoring the source address for
traffic entering the Switch. When the destination address
for inbound traffic is found in the database, the packets
intended for that address are forwarded directly to the
associated port. Otherwise, the traffic is flooded to all
ports.
You can query the forwarding database to find specific
dynamic MAC addresses, or view MAC addresses associated
with a specific interface or VLAN.
Dynamic Address Counts The number of addresses
dynamically learned on the Switch.
Interface Select to display MAC addresses for a specific
port or LAG.
MAC Address Select to display details for a specific MAC
address.
VLAN Select to display MAC addresses for a specific
configured VLAN (1-4094).
Address Table Sort Key Sorts the information displayed
based on MAC address, VLAN, or interface (port or LAG).
Specify the search type (that is, check the Interface, MAC
Address, or VLAN checkbox), select the method of sorting
the displayed addresses, and then click Query. The
dynamic addresses that conform to the search criteria are
displayed. To delete a MAC address from the forwarding
database, select the entry in the displayed list, then click
Remove.
