Choose
Configure Forwarding and Filtering Table
from the
Switch Configuration
menu to access the following
screen:
Figure 6-17. Filtering and Forwarding Table Configuration screen
The following fields at the top of the screen can be set:
♦
Lock Address Table(STOPs Learning)
Mostly used for
security purposes, when the forwarding table is locked the
Switch will no longer learn the MAC addresses for new hosts. If
your network configuration doesn’t change, locking the
forwarding table helps keep intruders off your network since
any packet coming from an unknown source address will be
dropped by the Switch.
♦
MAC Address Age-out Time
Enter the desired MAC address
age-out time in this field (1 to 9999 minutes) .
The
Custom Forwarding Table
displays a list of manually
defined static MAC address entries.
