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.
