Setting Description
Control
Enables you to configure control of the port. Select from:
(2) auto – the default setting. The switch controls the port and prevents the
insertion of incompatible ports which may cause disruption.
(3) bypass – removes a port from the zone. Use this mode to troubleshoot
ports.
(4) extl-loopback – 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.
(5) force 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.
(6) diagnostic-tx – allows you to transmit specific Ordered Sets for testing
purposes.
Beacon
When enabled, it forces both port LEDs to flash on and off continuously
on the selected port. You can use the beacon feature to remotely alert a
technician to take action on a specific port as identified by a system
administrator. The blinking overrides the state information display until
the beaconing is turned off.
Transmitter
Turns the transceiver connected to the port on or off.
Cascade mode
The current cascade mode (auto, none, tree, string) selected for the port.
Options:
auto – This setting automatically configures the connection type based on
information sent by other InSpeed switches. This is the default setting for
InSpeed-based managed switches.
none – The port is disabled.
tree – A port that 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 at the ASIC, a connection is made between the source and
destination ports. All ports are viewed as 100% FC_AL compliant.
string – A specially pre-allocated port designed to 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 on the ASIC, an
ARB is transmitted throughout the total string cascade loop to alert all
devices to enforce the Loop fairness rules. Therefore, if two devices try to
ARB for the loop at the same time, the higher Priority AL_PA will win the
cascade first, the lower priority one will follow.
Note: There must be two string ports on a zone. The port is configured for
a pair of string ports to other switches.
LIP on insert
If enabled, when a port inserts into a zone, it issues LIP(F7)s to other zone
members.
