Section 8. Dening 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 congured 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 ooded to all relevant VLAN ports. To

prevent the bridging table from overowing, a dynamic MAC address, from which no trafc arrives for a set period, is erased.

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

topics:

Conguring Static Addresses

Conguring Dynamic Forwarding Addresses

8.1 Conguring Static Addresses

The Forwarding Database Static Addresses Page contains parameters for dening 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 dene 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 elds:

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 specic LAG number to which the forwarding database parameters refer.

Status — Displays how the entry was created. The possible eld values are:

– Secure — The MAC Address is dened 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 eld values are:

– Checked — Removes the selected entry.

– Unchecked — Maintains the current static forwarding database.
