Description
The name of the port type setting. If using one of the
pre-defined port types, the name will automatically
appear.
The topology among switches for a port.
• Initiator or Target Port – the default setting. For when
there are no links among 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 a 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.
• insert – allows ports whose transceivers cannot
derive a valid clock or "K" character (ordered set) to
join the 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.
