Chapter 17 Address Commands<br />
Address configuration can improve the network security by configuring the Port Security and<br />
maintaining the address information by managing the Address Table.<br />
bridge address port-security<br />
Description<br />
The bridge address port-security command is used to configure port security.<br />
To return to the default configuration, please use no bridge address<br />
port-security command. Port Security is to protect the switch from the<br />
malicious MAC address attack by limiting the maximum number of the MAC<br />
addresses that can be learned on the port. The port with Port Security feature<br />
enabled will learned the MAC address dynamically. When the learned MAC<br />
address number reaches the maximum, the port will stop learning. Therefore,<br />
the other devices with the MAC address unlearned can not access to the<br />
network via this port.<br />
Syntax<br />
bridge address port-security [max-number {num}] [ mode {dynamic | static |<br />
permanent} ] [ status {disable | enable} ]<br />
no bridge address port-security<br />
Parameter<br />
num —— The maximum number of MAC addresses that can be learned on the<br />
port. It ranges from 0 to 64. By default this value is 64.<br />
mode —— Learn mode for MAC addresses. There are three modes, including<br />
Dynamic mode, Static mode and Permanent mode. When Dynamic mode is<br />
selected, the learned MAC address will be deleted automatically after the aging<br />
time. When Static mode is selected, the learned MAC address will be out of the<br />
influence of the aging time and can only be deleted manually. The learned<br />
entries will be cleared after the switch is rebooted. When permanent mode is<br />
selected, the learned MAC address will be out of the influence of the aging time<br />
and can only be deleted manually too. However, the learned entries will be<br />
saved even the switch is rebooted.<br />
status —— Enable or disable the Port Security function for a specified port. By<br />
default, this function is disabled.<br />
