Managing Ethernet MicroLAN Modules
Determining a Port’s Topology Status
There are three ways to determine whether a port’s topology status is currently station or
trunk:
• Bring up the port’s Statistics window, and check the Active Users field. If the Active
Users field displays zero, one, or two, the port is in station status; if it is three or more,
the port is in trunk status.
• Bring up the port’s Source Addressing window. If zero, one, or two source addresses
appear, the port is in station status; if three or more appear, the port is in trunk status.
• Use the Port Type option on the Port Status menu. The Device View port status display
will indicate which ports are serving as station ports, and which are serving as trunk
ports.
Locking and Unlocking all Ports on a Repeater Channel
You must have Administrative or SuperUser (SU) privileges to lock or unlock ports. The
community name used to define the device icon must provide complete access to the
device.
TIP
The only way to achieve a mixed lock status is by locking ports via the port-level Security
windows. If your Ethernet MicroLAN module is running firmware version 2.03.03 or
later, the repeater, port group (board), and port Security options will be available, and
the resulting windows will appear to allow you to set all security parameters. However,
only the Lock Port option actually has any effect, as the LANVIEW
SECURE
features are
only functional on modules which have been equipped with the appropriate hardware.
Contact the Enterasys Global Call Center or your local sales representative for more
information about purchasing Ethernet MicroLAN modules which support the
LANVIEW
SECURE
functionality.
NOTES
A port in station status may actually be connected to multiple devices; station status
simply indicates that no more than two devices are currently active. Once port locking is
enabled, each port’s topology status (trunk or station) remains fixed and will not change
while locking remains enabled, regardless of any changes in the number of source
addresses detected.
Note, too, that some older versions of firmware use slightly different definitions of station
and trunk ports: station ports are defined as those detecting zero or one source address;
trunk ports are those detecting two or more. Keep this difference in mind if your device is
running an older version of firmware.
