Configuring a port for long distance
14
Depending on the distance selected, this might require a license. For information about the
various distances, refer to Table 15.
If you select a long-distance setting of LD or LS, you must also enter a value in the Desired
Distance column for that port number:
a. Double-click the Desired Distance field for the port, as shown in Figure 32.
b. Enter a number in the field to indicate the distance in kilometers. The allowed values
depend on the port capability:
• If the port capability is 8 GB, type a number between 10 and 63 inclusive.
• If the port capability is 4 GB, type a number between 10 and 125, inclusive.
• If the port capability is 2 GB, type a number between 10 and 250, inclusive.
• If the port capability is 1 GB, type a number between 10 and 500, inclusive.
• For the Brocade 6510, Brocade DCX 8510-8 and Brocade DCX 8510-4, the buffer
credits are 10 through X; where X is proportional to the available buffers.
This value is the upper limit for calculating buffer availability for other ports in the same
port group. If the actual distance is more than the desired distance, the port operates in
buffer-limited mode.
c. Press Enter or click another port entry for the value to be accepted.
6. Click Apply.
The warning message, “DLS should be disabled while enabling Long distance link with Credit
Recovery” displays.
7. Cl ick Yes to apply the changes, or click No to close the confirmation message window.
