ALFairness
On an arbitrated loop, the switch is always highest priority when arbitrating for the right to transfer. To prevent other devices from being locked out, the standard provides for a fairness mode, which if enabled requires an arbitrater to let all other devices win arbitration before arbing a second time. (True / False).

ARB_FF
When ARB_FF is enabled, it causes the switch to send the ARB_FF primitive when it is in monitoring mode, rather than idles. The only reason to do this is since the ARB_FF has less bit transitions than does an idle, it produces less EMI. It has no other effect. (True / False)

An LED that indicates that the switch logic circuitry is receiving proper DC voltages

InteropCredit
This variable determines the number of credits we will advertise on an ISL. Non FC-SW-2 compliant firmware required that we match their offering (decimal value, 0-255). If you need more than 12 credits, the port must be set up as an extended credit port.

IP
Internet Protocol

ISLSecurity
ISLSecurity determines which switches a port will establish a link with. ANY - will link with any FC-SW-2 compliant switch. OURS  - will only link to another SANbox2 switch. NONE - the port will not establish an ISL link.

LCFEnable
True / False.  LCFEable gives preference to Link control frames (such as Class 2 ACK frames) over other frames when queued for transmission in the switch. This may provide better performance when running Class 2 traffic. LCFEable is incompatible with MFSEnable, and both cannot be selected.
