Configuring MAC Address Learning
Use the MAC Address > Learning Status page to enable or disable MAC address
learning on an interface.
Command Usage
◆ When MAC address learning is disabled, the switch immediately stops learning
new MAC addresses on the specified interface. Only incoming traffic with
source addresses stored in the static address table (see “Setting Static
Addresses” on page 209) will be accepted as authorized to access the network
through that interface.
◆ Dynamic addresses stored in the address table when MAC address learning is
disabled are flushed from the system, and no dynamic addresses are
subsequently learned until MAC address learning has been re-enabled. Any
device not listed in the static address table that attempts to use the interface
after MAC learning has been disabled will be prevented from accessing the
switch.
◆ Also note that MAC address learning cannot be disabled if any of the following
conditions exist:
■
802.1X Port Authentication has been globally enabled on the switch (see
“Configuring 802.1X Global Settings” on page 360).
■
Security Status (see “Configuring Port Security” on page 356) is enabled on
the same interface.
Parameters
These parameters are displayed:
◆ Interface – Displays a list of ports or trunks.
■
Port – Port Identifier. (Range: 1-28)
■
Trunk – Trunk Identifier. (Range: 1-26)
