Cisco Systems DSC9148D8G48PK9 manual Private Loop Configuration Guidelines

Chapter 2 Configuring Interfaces

Guidelines and Limitations

•The auto mode is not allowed in a 32-port switching module or the host-optimized ports in the Cisco 9100 Series (16 host-optimized ports in the Cisco MDS 9120 switch and 32 host-optimized ports in the Cisco MDS 9140 switch).

•The default port mode is Fx (Fx negotiates to F or FL) for 32-port switching modules.

•The 32-port switching module does not support FICON.

Note We recommend that you configure your E ports on a 16-port switching module. If you must configure an E port on a 32-port host-optimized switching module, the other three ports in that 4-port group cannot be used.

Note In the Cisco MDS 9100 Series, the groups of ports that are located on the left and outlined in white are full line rate. The other ports are host-optimized. Each group of 4 host-optimized ports have the same features as for the 32-port switching module.

Private Loop Configuration Guidelines

Follow these guidelines when configuring private loops:

•A maximum of 64 fabric devices can be proxy to a private loop.

•Fabric devices must be in the same zone as private loop devices to be proxy to the private loop.

•Each private device on a TL port may be included in a different zone.

•All devices on the loop are treated as private loops. You cannot mix private and public devices on the loop if the configured port mode is TL.

•The only FC4-type supported by TL ports is SCSI (FCP).

•Communication between a private initiator to a private target on the same private loop does not invoke TL port services.

VSAN Interface Configuration Guidelines

Follow these guidelines when creating or deleting VSAN interfaces:

•Create a VSAN before creating the interface for that VSAN. If a VSAN does not exist, the interface cannot be created.

•Create the interface VSAN—it is not created automatically.

•If you delete the VSAN, the attached interface is automatically deleted.

•Configure each interface only in one VSAN.

Tip After configuring the VSAN interface, you can configure an IP address or Virtual Router Redundancy Protocol (VRRP) feature. See the Cisco MDS 9000 Family NX-OS IP Services Configuration Guide.
