TL Ports

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 “Interface Modes” section on page 2-2.

TL port mode is not supported on the following hardware:

•Generation 2 switching module interfaces

•Cisco MDS 9124 Fabric Switch

•Cisco Fabric Switch for HP c-Class BladeSystem

•Cisco Fabric Switch for IBM BladeCenter

Table 2-6lists the TL port translations supported in Cisco MDS 9000 Family switches.
