Configuring Bridging Services
1-32 117351-A Rev. A
Parameter: Path Cost
Default: 1
Options: 1 to 65535
Function: When this port is the root port, the path cost is the contribution of the path
through this port to the total cost of the path to the root for this bridge.
When this port is not the root port, the path cost is added to the designated
cost for the root port and is used as the value of the root path cost offered
in all configuration BPDUs transmitted by the bridge.
To determine the path cost, use this formula:
Interface path cost = 1000/attached LAN speed in Mb/s
Instructions: Enter a path cost value. For example, enter 100 if the attached LAN is
Ethernet (1000/10 = 100).
MIB Object ID: 1.3.6.1.4.1.18.3.5.1.2.2.1.7
Flushing the Forwarding Table
You can clear (flush) all MAC addresses from the bridge’s forwarding table
without bringing the bridge down and back up. This function is only available
when you configure the bridge in dynamic mode.
To flush the tables, select Protocols > Bridge > Flush FWD Tables from the
Configuration Manager window (see F
igure 1-14 on page 1-19). The system
unlearns all MAC addresses it previously stored in its forwarding table and then
displays a confirmation message.
