TP-Link TL-SG3109, TL-SL3452 manual Defining the Forwarding Database, Configuring Static Addresses

Section 8. Defining the Forwarding Database

Packets addressed to destinations stored in either the Static or Dynamic databases are immediately forwarded to the port. The Dynamic MAC Address Table can be sorted by interface, VLAN, or MAC Address, whereas MAC addresses are dynamically learned as packets from sources that arrive at the device. Static addresses are configured manually.

An address becomes associated with a port by learning the port from the frame’s source address, but if a frame that is addressed to a destination MAC address is not associated with a port, that frame is flooded to all relevant VLAN ports. To prevent the bridging table from overflowing, a dynamic MAC address, from which no traffic arrives for a set period, is erased.

This section contains information for defining both static and dynamic forwarding addresses, and includes the following topics:

Configuring Static Addresses

Configuring Dynamic Forwarding Addresses

8.1 Configuring Static Addresses

The Forwarding Database Static Addresses Page contains parameters for defining the age interval on the device. To prevent static MAC addresses from being deleted when the device is reset, ensure that the port attached to the MAC address is locked. To prevent static MAC addresses from being deleted when the device is reset, ensure that the port attached to the MAC address is locked.

To define Static addressing for the forwarding database:

1.Click System > Bridging Config > Forwarding Database > Static Addresses. The Forwarding Database Static Addresses Page opens:

Figure 81: Forwarding Database Static Addresses Page

The Forwarding Database Static Addresses Page contains the following fields:

VLAN ID — Displays the VLAN ID number to which the entry refers.

MAC Address — Displays the MAC address to which the entry refers.

Interface — Displays the interface to which the entry refers:

–Port — The specific port number to which the forwarding database parameters refer.

–LAG — The specific LAG number to which the forwarding database parameters refer.

Status — Displays how the entry was created. The possible field values are:

–Secure — The MAC Address is defined for locked ports.

–Permanent — The MAC address is permanent.

–Delete on Reset — The MAC address is deleted when the device is reset.

–Delete on Timeout — The MAC address is deleted when a timeout occurs.

Remove — Removes the entry. The possible field values are:

–Checked — Removes the selected entry.

–Unchecked — Maintains the current static forwarding database.
