Configure Filtering And Forwarding Table - D-Link DES-3225G Series User Manual

STP Port Control
To change the parameters on individual ports:
1. Choose Configure Spanning Tree Protocol from the Configuration menu.
2. Choose STP Port Control from the Configure Spanning Tree Protocol menu. The following screen
appears:
Items in the above window are described as follows:
♦ STP State Enables or disables the Spanning Tree Protocol on a particular port.
♦ Cost This is a read-only object. The 100Mbps segment has an assigned Path Cost of 19, and each
10Mbps segment also has an assigned Path Cost of 19, based on the STA specifications.
♦ Priority Port Priority is a read-write object that can be set from 0 to 255. This is the priority number
of the port. The lower the port priority, the more chance the bridge has of becoming the root port. Zero
is the highest priority.

Configure Filtering and Forwarding Table

When a packet hits the Switch, it looks in the filtering and forwarding table to decide what to do with the
packet; either to filter it off the network, or to forward it through the port on which its destination lies.
Dynamic Filtering and Static Filtering are among the two important features of the Custom Filtering
Table. They are defined here briefly as follows. Dynamic Filtering is defined when a dynamic entry is created
by the Learning Process as a result of observation of network traffic in the Filtering Database. Static Filtering
is defined as static entries that may be added and removed from the Filtering Database by the user. They are
not automatically removed by any timeout mechanism.
