Port Level Security Configuration Screen
2E43-51/2E43-51R User’s Guide 5-67
• NonSecure – Allows the ports on the connector to receive all frames.
The source address of received frames is not examined and the frames
are processed in a non secure state.
Lock/Learn (Selectable)
Used to select the type of security for frames received by any port on the
connector. The security types are as follows:
• LockOnNext – The next frame received by each port is examined to
learn its source address. As the source address of a frame is learned on
a port, only those frames received with that same source address are
processed on that port. As each port is locked on the next address, the
device executes the actions selected in the Action On Intruder field.
• LockedOnAddr – The source address of the last frame received (or the
source address entered in the Port Level Security Configuration
screen, if one is entered) is used for security purposes. Once a secure
address is defined on a port, only those frames received with that same
source address are processed on that port. Any other frame detected
with a different address is considered as an intruder, causing the device
to execute the actions selected in the Action On Intruder field.
Action On Intruder (Toggle)
Used to select the actions taken for the selected security state. There are
two fields to select the actions. Both toggle to activate or deactivate the
action.
• DisablePort/NoDisable – DisablePort causes the switch to turn off the
port that had a security violation. With NoDisable set, the port is not
turned off.
• SendTrap/NoTrap – SendTrap causes the switch to send an SNMP trap
when a port detects a security violation. With NoTrap set, no SNMP
trap is sent.
Secure Address (Modifiable)
Used to enter the source address for the LockedOnAddr security state
setting. Once a secure address is defined on a port, only those frames
received with that same source address are processed on that port. Any
other frame detected with a different address is considered as an intruder,
causing the device to execute the actions selected in the Action On
Intruder field. When the security state setting is NonSecure, the field
displays the source address of the last frame.
