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
switch# show tlport interface fc1/16 all
fc1/16 is up, vsan 1, FCID 0x420000
--------------------------------------------------------------------------------
alpa pWWN nWWN SCSI Type Device FC-ID

0xef 20:10:00:05:30:00:4a:de 20:00:00:05:30:00:4a:de Initiator Switch 0x0000ef
Example 2-19 Displays TL Port Information for Private Devices
switch# show tlport interface fc 1/16 private
fc1/16 is up, vsan 1, FCID 0x420000
------------------------------------------------------------------------
alpa pWWN nWWN SCSI Type FC-ID

0x73 22:00:00:20:37:39:ae:54 20:00:00:20:37:39:ae:54 Target 0x420073
0x74 22:00:00:20:37:38:d3:de 20:00:00:20:37:38:d3:de Target 0x420074
Example 2-20 Displays TL Port Information for Proxied Devices
switch# show tlport interface fc 1/16 proxied
fc1/16 is up, vsan 1, FCID 0x420000
------------------------------------------------------------------------
alpa pWWN nWWN SCSI Type FC-ID
------------------------------------------------------------------------
0x01 20:10:00:05:30:00:4a:de 20:00:00:05:30:00:4a:de Initiator 0xfffc42
0x02 21:00:00:e0:8b:01:95:e7 20:00:00:e0:8b:01:95:e7 Initiator 0x420100
Displaying the ALPA Cache Contents
The show tlport alpa-cache command displays the contents of the ALPA cache.
switch# show tlport alpa-cache
---------------------------------------------------------
alpa pWWN Interface
---------------------------------------------------------
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).
Displaying Port Monitor Status and Policies
The following commands display information regarding port monitor:
