Chapter 2 Configuring Interfaces

Verifying Interfaces Configuration

In addition to these proxied devices, other virtual devices (local or remote domain controller addresses) are also allocated ALPAs on the loop. A switch reserves the ALPA for its own communication with private devices, and the switch acts as a SCSI initiator.

The first column in the output of the show tlport interface command is the ALPA identity of the device on the loop. The columns that follow include the port WWNs, the node WWNs for each device, the device as a SCSI initiator or target, and the real FC ID of the device.

Example 2-18 Displays the Detailed Information for a Specific TL Port

Displaying the ALPA Cache Contents

The show tlport alpa-cachecommand displays the contents of the ALPA cache.

switch# show tlport alpa-cache

0x02	22:00:00:20:37:46:09:bd	fc1/2
0x04	23:00:00:20:37:46:09:bd	fc1/2

The first entry indicates that if a device with a pWWN of 22:00:00:20:37:46:09:bd is exported on TL port fc1/2, then the pWWN is allocated an alpa 0x02 (if available).
