Configuring Security Features 4 - 19
The following command example displays a Security Intrusion list for a
two-port 10BASE-FB Module.
ONline> show security intruder_list [ENTER]
Port
MAC Address Time Since Intrusion Auto-Disable?
03.01 08-00-8f-02-c6-be 0d 0h 15m 27s YES
03.02 09-d3-74-00-2e-01 1d 5h 32m 53s YES
MAC addresses for unauthorized stations that attempt to transmit data to
Security Module ports are not displayed. The MAC addresses are not
displayed because the MAC address is intercepted by Intrusion Detection,
and cannot reach the network where the EMM can detect the MAC
address.
Clearing Security Configurations
The Security Module provides commands to clear a MAC address from a
port's MAC address table, and from the Autolearning Database. A cleared
MAC address is no longer considered to be a valid address. A command is
also available to clear the Security Intruder list.
Clearing the MAC Address Table
You may want to manually clear a MAC address from a port instead of
initiating Autolearning to recapture a port's associated MAC addresses. For
example, once Autolearning Capture has completed and the information
downloaded, a station may be removed from the network.
Issue the following command to clear the MAC address 08-54-6f-01-32-08
from the MAC address table for port 1 on the Security Module in slot 3.
ONline> clear security port 3.1 mac_address 08-54-6f-01-32-08 [ENTER]
Use the All option to remove all associated MAC addresses from a specific
port, all ports on a Security Module, or all ports on all Security Modules in a
concentrator. If you do not enter a MAC address, the command defaults to
All, which clears all MAC addresses from the specified ports.
