Configuring a Port for Long Distance
8
a. Double-click the Desired Distance field for the port, as shown in Figure 8-1.
b. Type a number in the field to indicate the distance in kilometers.
For 1 Gbit/sec ports, type a number between 10 and 500, inclusive.
For 2 Gbit/sec ports, type a number between 10 and 250, inclusive.
For 4 Gbit/sec ports, type a number between 10 and 125, inclusive.
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. Optional: If the fabric contains SilkWorm 2000-series extended ISLs, click the On radio button for
Long Distance Compatibility.
The switch must be disabled before you can select this option.
If you select this option, you must have an Extended Fabrics license, and both E_Ports in an ISL
must be configured with the same long-distance compatibility setting. SilkWorm 4100 switches
cannot be part of such a fabric.
7. Click Apply.
