Table 15 MAC Address Security Configuration screen fields
Field Description
MAC Address Security When this field is set to enabled, the switch checks source MAC addresses
of packets that arrive on secure ports against MAC addresses listed in the
MAC Address Security Table for allowed membership. If the switch detects a
source MAC address that is not an allowed member, the switch drops the
packets.

Clear by Ports This field clears the specified port (or ports) that are listed in the Allowed
Source Port(s) field of the MAC Address Security Table screen (see
“MAC
Address Security Table screens” on page 117 ). When you specify a port (or
ports) to be cleared using this field, the specific port (or ports) will be cleared
for each of the entries listed in the MAC Address Security Table. If you totally
clear the allowed Source Port(s) field (leaving a blank field) for an entry, the
associated MAC address for that entry is also cleared.
Default NONE
Range NONE, ALL, a port number list (for example, 1, 6, etc.)
Learn by Ports All source MAC addresses of any packets received on the specified port (or
ports) are added to the MAC Security Table when the Current Learning Mode
field is set to Learning in Progress. You cannot include any of the port values
whose security is enabled. You must disable port security for that port.
Default NONE
Range NONE, ALL, a port number list (for example, 1, 6, etc.)
Current Learning Mode Indicates the current learning mode for the switch ports. When this field is set
to Learning in Progress, all source MAC addresses of any packets received
on the specified port (or ports) are added to the MAC Security Table
(maximum of 448 MAC address entries allowed). If you exceed the limit of
448 entries, the system prompts you with an alert message.
