About TL Ports
TL port mode is not supported on the following:
• Generation 2 switching module interfaces
•
Cisco MDS 9124 Fabric Switch
• Cisco Fabric Switch for HP c-Class BladeSystem
•
Cisco Fabric Switch for IBM BladeCenter
Private loop devices refer to legacy devices that reside on arbitrated loops. These devices are not aware
of a switch fabric because they only communicate with devices on the same physical loop.
The legacy devices are used in Fibre Channel networks and devices outside the loop may need to
communicate with them.The communication functionality is provided through TL ports. See the
“About
Interface Modes” section on page 12-3 .
Follow these guidelines when configuring private loops:
•
A maximum of 64 fabric devices can be proxied to a private loop.
• Fabric devices must be in the same zone as private loop devices to be proxied 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.
Table 12-6 lists the TL port translations supported in Cisco MDS 9000 Family switches. Figure 12-4
shows examples of TL port translation support.
