MAC Address Filtering
TFortis switches support MAC address filtering for ports.
Figure 5.3.21.1 Configuring the port operating mode
In
Normal
state, the port operates in normal mode, performing packet
switching as usual, allowing any MAC addresses.
When the port is switched to
Secure
state, only MAC address added manually
to
MAC Address Table
can access this port
.
There are also several options how the
port reacts to an unauthorized MAC address:
Secure: MAC Filtration
– if an unauthorized MAC address is detected on the
port, only this MAC address is blocked and the port continues to operate.
Secure: Port shutdown
2 if an unauthorized MAC is detected on the port, the
port is blocked, data transmission stops.
Secure: Temporary port shutdown
– if an unauthorized MAC address is
detected on the port, the port is blocked for 5 minutes, data transfer stops. After
this timeout, the port switches back to transmit data. While unauthorized MAC
remains the ports blocks again.
To add a new authorized MAC address, use
Add New MAC Address
table. In order
to do so, provide a MAC address and a port number.
