Forwarding tab
The Forwarding tab shows the forwarding database for the VLAN and contains information about unicast entries for which the bridge has forwarding and/or filtering information.This information is used by the transparent bridging function to determine how to forward a received frame.
To access the Forwarding tab:
- From the Device Manager menu bar, choose VLAN > VLANs.
| The VLAN dialog box opens with the Basic tab displayed. |
- Select a VLAN.
- Click the Bridge button.
| The VLAN, Bridge dialog box opens with the Transparent tab displayed. |
- Click the Forwarding tab.
| The VLAN, Bridge, Forwarding tab opens. |
The table below describes the Forwarding tab items.
|
Status
|
Values include:
- self--one of the bridge's addresses
- learned--a learned entry that is being used
- mgmt--a static entry
|
MacAddress
|
A unicast MAC address for which the bridge has forwarding and/or filtering information.
|
Port
|
Either a value of zero (0) or the port number of the port on which a frame having the specified MAC address has been seen. A value of 0 indicates a self-assigned MAC address.
|
Monitor
|
Select true or false to copy packets with MAC address in source or destination field. Used with port mirroring.
|
Priority
|
Priority level. If true, frames in the VLAN are forwarded through the switch fabric with high priority.
If false, frames in the VLAN are forwarded through the switch fabric with normal priority.
|

Note:
For troubleshooting, it is sometimes necessary to manually flush the bridge forwarding database of learned MAC addresses. You can flush the forwarding database in two contexts:
- By Port--Delete all MAC addresses associated with a port for all VLANs under Edit Port > Interface > Action > FlushMacFdb.
- By VLAN--Delete all MAC addresses associated with the VLAN under VLAN > VLANs > Advanced > Action > FlushMacFdb.
