Chapter 2: LM Security Screens for 6E123-50 and 6E133-49

Local Management Supplement
The following section defines the fields on the Port Level Security
Configuration screen.
Port (Read-only)
Lists the repeater port on the ENET interface connector (ENET 1
through 4) selected in the INTERFACE # field. Refer to
Table 2-1
for the
ENET/repeater port relationship on the device.
Table 2-1
ENET/Repeater Port Relationship
Security State (Selectable)
Used to select the security state for each port on the connector for frames
received. The states are as follows:
•
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. The last source address detected is
displayed in the address column. This provides a quick and easy way
to see what address belongs to what port.
•
LockOnNext – The next frame received by each port is examined to
learn its source address. After the source address of a frame is learned
on a port, it is now locked on that address and only those frames
received with that same source address are allowed on that port. All
frames received that do not have that same source address will cause
the device to execute the actions selected in the Action On Intruder
field.
•
LockedOnAddr – The port locks down on the address that is currently
configured in the Port Level Security Configuration screen (if one is
entered) or on the source address of the currently received frame. If an
address is not configured or received, the device assumes the default
address of “00-00-00-00-00-00” as the locked on address as indicated
by the address fields in
Figure 2-3
. When a port is locked on an address
and a frame received violates the set security, the actions selected in
the Action On Intruder field are executed.
ENET 1 = Repeater ports 1 – 12
ENET 3 = Repeater ports 25 – 36
ENET 2 = Repeater ports 13 – 24
ENET 4 = Repeater ports 37 – 48
