5.5.3 Configuring a port
This section describes how to configure port options such as, long distance buffering, port
binding, and speed.
If the 10-100 km feature is enabled, more buffer-to-buffer credits are provided to a port in
support of long distance links. The speed for each port should be set to the speed supported
by the attached device:
1. Click
Configure from the Products view of a Director, then select Ports from the menu.
The Configure Ports panel is displayed, as shown in Figure 5-21.
Figure 5-21 Configure ports
2. Check the check box in the 10-100 km column for ports that require the long distance
feature.
With this option, the buffer-to-buffer credit will automatically to changed to 60 for the port,
overriding the buffer-to-buffer credit defined for the Director, as shown in 5.4, “Building a
fabric” on page 52.
3. If the speed of the port should not be negotiated, click the
Speed field of a given port and
select the speed from the pull-down.
4. If port binding is required, click the
check box and add the WWPN of the device in the
Bound WWN field that will be attached to that particular port.
5. Once all ports are configured, click the
Activate button to activate and save changes.
5.6 Zoning
Zoning is required to group several ports or WWNs into a zone. Several zones can be created
holding different ports or WWNs. All zones are then grouped into a zone set. The zone set
has to be activated in a Director, and is automatically propagated to all other Directors in the
fabric.
