Description
Use this command to allocate enough full-size frame buffers on a particular port to support a
long-distance link up to 500 km. The port can only be used as an F/FL/E_Port. F/FL_Ports can be
configured only for long distance using LE, L0.5, L1, or L2 modes. Changes made by this command are
persistent across switch reboots or power cycles.
The value of
distance_level
can be one of the following (the numerical value representing each
distance_level
is shown in parentheses):
The
vc_translation_link_init
option is used to enable the long-distance link initialization
sequence.
desired_distance
is a required parameter to configure a port as an LD-mode link. The desired
distance is used as the upper limit of the link distance to calculate buffer availability for other ports in the
same port group. When the measured distance is more than
desired_distance
, the
portCfgLongDistance
L0 (0)
Reconfigure the port to be a regular switch port. A total of 20 full-size frame
buffers are reserved for data traffic, regardless of the port’s operating speed.
L0.5
Level 0.5 (
portCfgShow
displays the two-letter code as LM) long distance, up to
25 km.
L1 (1)
Level 1 long distance, up to 50 km.
L2 (2)
Level 2 long distance, up to 100 km. For previously released switches
(Bloom1-based), the number of frames buffers is limited to 63.
LE (3)
Level E mode is for E_Ports for distances beyond 5 km and up to 10 km. LE does
not require an Extended Fabrics license.
LD
Automatic 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 250
full-size frame buffers are reserved, depending upon the distance measured
during E_Port initialization. If the desired distance is provided, it is used as the
upper limit to the measured distance. For Bloom1-based systems, the number of
frame buffers is limited to 63.
You can also configure a long-distance link as part of a trunk group (see
portCfgTrunkPort
). Two or more long-distance links in a port group forms a
trunk group when they are configured for the same speed, the same distance
level, and their link distances are nearly equal.
For details about buffer allocation at specific speeds and distances, see the
