24 Port Stackable Managed Switch – User Guide Page 30
MAC Address Configuration
This menu section is selected from the Switch Configuration menu screen and enables
configuration of the static or filtered MAC addresses. These settings are only needed for
certain security operations and are not generally used. It is also possible from this option to
view MAC addresses that have been learnt by the Switch.
In some instances, it is necessary to manually apply a fixed or static address into the tables of
the Switch. When you add a static MAC address, it remains in the Switch's address table,
regardless of whether the device is physically connected to the Switch. This saves the Switch
from having to learn a device's MAC address.
Static MAC Address
From the MAC Address Configuration menu select the option Static MAC Address. A new
menu is displayed listing the existing static MAC addresses. Select <add> from the action
line. A new menu is displayed that requests the MAC address value and the physical port that
is associated with the static address value. If VLANS are configured it will also request a
VLAN ID. When these values have been entered, use the <esc> key to return to the action
line and then select the <apply> to ensure that the MAC values are stored. The menu will
display each static MAC address configured, the associated port and VLAN ID.
Filtering MAC Address
There maybe times when filtering packets based on the destination MAC address is needed.
This is achieved using Filtering MAC Address menu, selected from the MAC Address
Configuration menu. After selecting this option a new menu is displayed listing the current
MAC addresses that are being filtered and their associated VLAN ID. Select <add> from the
action line. A new menu is displayed that requests the MAC address value to be filtered and if
VLANS are configured, the VLAN ID value. When these values have been entered, use the
<esc> key to return to the action line and then select <apply> to ensure the configuration is
saved.
All MAC Addresses
There can be occasions when it is useful to determine what MAC addresses have been learnt
on a port for troubleshooting reasons. Select All MAC Addresses from the MAC
Configuration Menu. Now choose <select> from the action line and use the <spacebar> to
list port number options. Select the port to be viewed by pressing <enter>. A new screen is
now displayed showing a list of MAC addresses that have been learnt on this port, and their
associated VLANID. The Status field shows if the MAC address is Dynamic (learnt) or Static.
NOTE: This option currently only works on a Standalone or Master Switch
