2 portCfgLongDistance Operands desired_distance is a required parameter to configure a port as an LD and LS-mode link. For 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 desired_distance is used to allocate the buffers. In this case, the port operates in degraded mode instead being disabled due to insufficient buffers. For an LS-mode link, the actual distance is not measured, instead the desired_distance is used to calculate the buffers required for the port. Pressing Ctrl-D cancels the configuration update. 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 follows: L0 normal LE standard

Fabric OS Command Reference Manual

portCfgLongDistance

desired_distance

is a required parameter to configure a port as an LD and LS-mode link. For 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

desired_distance

is used to allocate the buffers. In this case, the port

operates in degraded mode instead being disabled due to insufficient buffers. For an LS-mode link,

the actual distance is not measured, instead the

desired_distance

is used to calculate the buffers

required for the port.

Pressing

Ctrl-D

cancels the configuration update.

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

follows:

normal

standard <= 10 Km

auto

static

In the

switchShow

output, the long distance mode displays as L

, where

is the second letter in

two-letter distance-level code described.

The

portCfgISLMode

and

portCfgLongDistance

LE, LD, or LS levels only can be enabled at the

same time. Such an ISL uses R_RDY mode of flow control over the long-distance link. While using

R_RDY mode flow control, an E_Port cannot form trunk groups of long-distance links even if the

trunking is enabled. This feature is not backward compatible with firmware versions that do not

support it.

If a port is configured as a long distance port, the remaining ports of that port group could be

disabled, fail to initialize, or move to “buffer limited” mode due to a lack of frame buffers.

For the Brocade 3250, 3850, and 3900 switches and Brocade 24000 and 48000 directors using

FC2-16 port blades, each port group contains four ports and uses a common pool of credits.

Because the number of credits available for use within each port group is limited, configuring ports

for extended links on these platforms might cause other ports to disable, if there are not enough

buffer credits available. Brocade 200E,4100, and 4900 switches and Brocade 48000 directors

using FC4-16 and FC4-32 port blades, buffer credits are used by all ports on the chip.

Buffer-limited port technology allows all ports to remain operational, even when extended links are

in use.

The execution of this command is subject to Admin Domain restrictions that may be in place.

Operands

This command has the following operands:

slotnumber

Specifies the slot number, for bladed systems only. The slot number must be

followed by a slash (/).

portnumber

Specifies a port number. Valid values for port number vary, depending on the

switch type. Use

switchShow

to display a list of valid ports. This operand is

required.

distance_level

Refer to the “Description” section for information about the value.
