When this command is invoked without the optional operand, you are
prompted to enter the long-distance level number. The level value must be
one of the following:
You can cancel the configuration update by entering CTRL + D.
When a port is configured to be a long-distance port, the output of
portShow
and
switchShow
displays the long-distance level. In the
portShow
output, the long-distance level is indicated as “
medium
” for
Level 1 long-distance, and “
long
” for Level 2 long-distance. In the
switchShow
output, the format is
Lx
, where
x
is the long-distance level
number, except for Level 0, which is not displayed in
switchShow
.
Operands
The following operand is required:
The following operand is optional:
Limitations
A group of four adjacent ports that share a common pool of frame buffers
(for example, ports 0 to 3 or 4 to 7) are called a “quad.” Because the total
number of frame buffers in a quad is limited, if one of the ports in the quad
is configured as a long-distance port, none of the remaining ports in the
quad can be a long-distance port; they must all be Level 0 ports.
Level
Effect
0
Reconfigures the port as a regular switch port. The
number of buffers reserved for the port supports links
up to 10 km.
1
Level one long-distance, up to 50 km. A total of 27
full-size frame buffers are reserved for the port.
2
Level two long-distance, up to 100 km. A total of 60
full-size frame buffers are reserved for the port.
port_number
Number of port to be configured: 0 to7 or 0 to15.
long_distance_level
0 = reconfigure port to be regular switch port
1 = level one long-distance (up to 50 km)
2 = level two long-distance (up to 100 km)
