JetStream 52-Port Gigabit Stackable L3 Managed Switch CLI Guide
Parameter
num
—— The maximum number of MAC addresses that can be learned on
the port. It ranges from 0 to 1024. By default this value is 1024.
dynamic | static | permanent —— Learn mode for MAC addresses. There are
three modes, including Dynamic mode, Static mode and Permanent mode.
When Dynamic mode is selected, the learned MAC address will be deleted
automatically after the aging time. When Static mode is selected, the learned
MAC address will be out of the influence of the aging time and can only be
deleted manually. The learned entries will be cleared after the switch is
rebooted. When permanent mode is selected, the learned MAC address will
be out of the influence of the aging time and can only be deleted manually too.
However, the learned entries will be saved even the switch is rebooted.
status —— Enable or disable the Port Security function for a specified port.
By default, this function is disabled.
