Sets the desired distance attribute for a Fibre Channel port used in the Dynamic (LD) or Static

Long-Distance (LS) modes.

Synopsis desire-distance distance

no desire-distance

Operands distance The length (in km) of the desired link.

Defaults The default is 0.

Command Modes Interface Fibre Channel configuration mode

Description For a Fibre Channel link configured with Static Long Distance (LS) mode, use this command to set

the length of the desired long distance. The calculation of buffer-to-buffer credits is based on this

length.

For a long distance Fibre Channel link configured with Dynamic mode (LD), use this command to

set the maximum length to be used in calculating buffer-to-buffer credits. In this mode, the smaller

of the distance measured during port initialization and the desired distance is used in the

calculation.

Usage Guidelines This command can be used only on Network OS platforms with Fibre Channel ports

(Brocade VDX 6730-32 and Brocade VDX 6730-76 switches), in Brocade VCS Fabric mode, and

with the FCoE license installed.

Use the no form of this command to disable it.

Examples To set the desired distance Fibre Channel port attribute:

switch(config)# interface FibreChannel 7/0/2

switch(config-FibreChannel-7/0/2)# long-distance ls

switch(config-FibreChannel-7/0/2)# desire-distance 100
