Fabric OS reference guide
200 Fabric OS 3.x Document Addendum
The long-distance level string must be one of the following:
The VC (virtual channel) translation link initialization parameter must be set to 1 for long
distance. When set to 1, this parameter indicates that the enhanced link reset protocol is used
for long-distance links. When this parameter is not specified by the user, it is set to 1 by
default. To be compatible with earlier Fabric OS v3.x implementations, 0 can be used for this
parameter.
When a port is configured as a long-distance port, portCfgShow and
switchshow
output
displays the long-distance level as Lx, where x is 0, 0.5, 1, 2, D, or E. The
portCfgShow
command also displays the current setting for the VC translation link initialization parameter.
Extended Fabrics mode is not supported when interoperable mode is enabled.
Note: The portcfgislmode and
portcfglongdistance
modes cannot both be enabled at the
same time; otherwise, the fabric segments.
Operands
The following operand is required:
The following operands are optional:
L0
Reconfigure the port to be a regular switch port. The number of buffers
reserved for the port supports up to 10 km links at 1 Gbit/sec.
LE
Level E mode is for E_Ports for distances beyond 5 km and up to 10
km. The number of buffers reserved for the port supports up to 10 km
links at 1 Gbit/sec and 2 Gbit/sec. LE does not require an Extended
Fabrics license.
L0.5
Level 0.5 long distance, up to 25 km.
L1
Level 1 long distance, up to 50 km.
L2
Level 2 long distance, up to 100 km.
LD
Dynamic long-distance configuration. The buffer credits for the given
E_Port are automatically configured based on the actual link distance.
Up to a total of 63 full-size frame buffers are reserved, depending upon
the distance measured during E_Port initialization.
port_number
The port number to be configured: 0 through 7 or 0 through 15.
long_distance_level
See the “ Description ” on page 199 section for the
meaning of this value. The default value is
LD
(dynamic long distance).
