This column shows the current state of the port as
seen from the Limit Control's point of view. The state
takes one of the following four values:
Disabled: Limit Control is either globally disabled or
disabled on the port.
Ready: The limit is not yet reached. This can be shown
for all actions.
Limit Reached: Indicates that the limit is reached on
this port. This state can only be shown if Action is set
to None or Trap.
Shutdown: Indicates that the port is shut down by the
Limit Control module. This state can only be shown if
Action is set to Shutdown or Trap & Shutdown.
Disabled
The
Reopen
button can be used to reopen a specific port that has been shut down due to exceeding
the defined limit.
3.12.6.2 Port Security Status
When port security is enabled on a port, the port is set-up for software-based learning. In this mode,
frames from unknown MAC addresses are passed on to the port security module, which in turn
checks all internal programming (user modules) whether to allow this new MAC address to forward or
block it. For a MAC address to be set in the forwarding state, all enabled user modules must
unanimously agree on allowing the MAC address to forward. If only one chooses to block it, it will be
blocked until that user module decides otherwise.
The status page is divided into two sections - one with a legend of user modules and one with the
actual port status.
