Abbr
A one-letter abbreviation of the user module. This is used in the Users column in the port
status table.
Port Status
The table has one row for each port on the selected switch in the stack and a number of
columns.
Port
The port number for which the status applies. Click the port number to see the status for
this particular port.
Users
Each of the user modules has a column that shows whether that module has enabled Port
Security or not. A '-' means that the corresponding user module is not enabled, whereas a
letter indicates that the user module abbreviated by that letter (see Abbr) has enabled port
security.
State
Shows the current state of the port. It can take one of four values:
Disabled:
No user modules are currently using the Port Security service.
Ready:
The Port Security service is in use by at least one user module, and is
awaiting frames from unknown MAC addresses to arrive.
Limit Reached:
The Port Security service is enabled by at least the Limit Control
user module, and that module has indicated that the limit is reached and no more
MAC addresses should be taken in.
Shutdown:
The Port Security service is enabled by at least the Limit Control user
module, and that module has indicated that the limit is exceeded. No MAC addresses
can be learned on the port until it is administratively re-opened on the Limit Control
configuration Web-page.
MAC Count (Current, Limit)
The two columns indicate the number of currently learned MAC addresses (forwarding as
well as blocked) and the maximum number of MAC addresses that can be learned on the
port, respectively.
If no user modules are enabled on the port, the Current column will show a dash (-).
If the Limit Control user module is not enabled on the port, the Limit column will show a
dash (-).
