Displaying port configuration information (root/config/port/show)
This command displays the port configuration and policy settings.
To view the port configuration and policy settings:
1. From the Port Configuration menu (root/config/port), type show and press E
A list of port configuration information appears for each port.

Description
The port number.
The current port state: bypassed, inserted, or rxLoss.
The topology among switches for a port.
• nonCascade– the default setting. No links exist between switches.
• Tree – allows arbitration fairness to other cascaded InSpeed-based
switches or ports connected to end devices. If the port is a tree port
then the ARB (Arbitrate) is sent down the port and, when the ARB is
received back, a connection is made between the source and
destination ports. All ports are viewed as 100% FC-AL compliant.
• String0 through String3 – designates the string to which a port is
assigned. Strings maintain fairness when two or more InSpeed-
based storage switches are serially cascaded. When the destination
port is a string and an OPN is received, an ARB is transmitted
throughout the total string cascade to alert all devices to enforce
fairness rules. Therefore, if two devices try to ARB at the same time,
the higher Priority AL_PA will win the cascade first, the lower priority
one will follow.
Note: There may be no more than two string ports in a zone.
The method for controlling a port.
• auto – the default setting. The switch will automatically insert a port
based on policy settings. This prevents the insertion of incompatible
ports, which may cause disruption.
• bypass – removes a port from the zone. Use this mode to keep a
device out of an initialization cycle when troubleshooting.
• extLoopback – removes a port from the zone and routes the port's
receive signal back through the port's transmitter. Use this mode to
isolate a specific zone for troubleshooting or test a transceiver's
circuitry and attached media from the node end.
• insert – allows ports whose transceivers cannot derive a valid clock
or "K" character (ordered set) to join a zone. Use this mode
cautiously – devices without valid characters may put bad data into
the zone, causing the zone to go down.
Enables or disables the transceiver connected to the port.
