Configure Port Security
Port security can be configured for each subscriber port. Port security is used to limit the number of MAC addresses allowed on the port. Specify up to 16 MAC addresses allowed per port. This feature functions similar to a static forwarding table. For example, if you choose to allow 10 MAC addresses, the first 10 MAC addresses forwarded from that port are entered into a static table that never ages out. All packets originating from or destined for the port must contain one of the allowed MAC addresses (listed in the static table) in the header or it will be dropped.
To configure port security settings:
1.Highlight Configure Port Security from the Configure Ports menu and press Enter to see the Configure Port Security screen.
2.The Configure Port Security screen displays current security status of each port.
Information about each subscriber port listed in the Configure Port Security Screen includes:
Port | Subscriber port number |
Lock | Enabled or Disabled (Default = Disabled) |
No. of MAC | Number of MAC addresses allowed for the port |
