• INV (invalid configuration) — the port is in an unrecognized state.
• TST (testing) — the port is in a testing mode.
Type
A switch interface’s Type is a dynamic value determined by the type of node to
which the interface is connected:
• Ntwk (network) — a Network interface is connected to another switch.
• Access — an Access interface is connected to an end node (a single user, a
shared resources such as a server or print, or a non-switch shared access
interface such as a bridge).
• Hybrid — though this feature is not yet supported, future firmware versions
will allow a switch interface to service both another switch and an end node.
This kind of configuration could occur, for example, on an FDDI ring.
• GoAcc (going to access) — a transitional state experienced by an interface
which is in the process of switching to access mode.
• Unkn (unknown) — on boot-up, all switch interfaces have a type value of
unknown; this value will convert dynamically as required by the connected
node.
Switch Port Color Codes
The color codes assigned to each port interface in Switch Application mode
indicate the following status conditions:
• Red — the port is administratively enabled, but not operational. This state
generally indicates that a network problem has shut down the port, even
though it is still administratively enabled; it can also indicate an invalid port
configuration.
• Blue — the port is both administratively and operationally disabled.
• Green — the port is administratively enabled and operational.
• Yellow — the port is in a transitional state: an operational status of either
enable or disable is pending, or the port has been administratively disabled,
but is (temporarily) still operational.
• Magenta — the port is in a transitional testing mode.
Note that the color coding scheme is the same regardless of the port display form
selected.
