Location ID

The Location ID parameter is reserved for future use and it must remain
unchanged with the default value of 0.

Disable FID Check

If fabric ID (FID) check is disabled, the fabric ignores the Fabric Identifier conflict
with the neighboring switch during fabric formation. By default, FID check is
enabled. If the fabric detects a FID conflict, it disables the E_Port with a "Fabric ID
conflict" message. This parameter is configurable only if the switch is Virtual
Fabric-aware and Virtual Fabric is enabled on the switch.

Enable 256 Area limit

The 256 area limit allows the partition to be configured for 8-bit addressing rather
than the default 10-bit addressing. Each port in this partition is given a unique
area represented by the middle 8 bits of the PID. Valid values include the
following:

0

No limit is imposed on the area. This is the default value. The partition is
configured for 10-bit addressing and supports up to 1800 ports.

1

The unique area assignments begin at zero regardless of where the port is
physically located. This allows FICON users to make use of high port count port
blades with port indexes greater than 256.

2

The unique area assignments are based on the port index. This mode does not
allow FICON users to make use of ports with an index greater than 256 (high ports
of a high port count blade), but this mode is compatible with domain-index zoning.
This parameter is configurable only if the switch is Virtual Fabric-aware and Virtual
Fabric is enabled on the switch.

R_A_TOV

The resource allocation time out value specified in milliseconds. This variable
works with the variable E_D_TOV to determine switch actions when presented
with an error condition.

Allocated circuit resources with detected errors are not released until the time
value has expired. If the condition is resolved prior to the time out, the internal
time-out clock resets and waits for the next error condition.

E_D_TOV

Error detect time out value specified in milliseconds. This timer is used to flag a
potential error condition when an expected response is not received within the set
time limit. If the time for an expected response exceeds the set value, then an
error condition occurs.

WAN_TOV

Wide area network time out value specified in milliseconds. This timer is the
maximum frame time out value for a WAN, if any, interconnecting the Fibre
Channel islands.

MAX_HOPS

Maximum hops is an integer that denotes the upper limit on the number of hops a
frame might have to traverse to reach any destination port from any source port
across the fabric.
