Brocade DCX porttest command

Hi,

Need a little guidance regarding the output from a porttest command. Below output shows command BEFORE the sfp in the port was replaced:

Port 273 : FAIL
PortType: F PORT
PortState: TEST DONE
PortInternalState: INIT
PortTypeToTest: NO_TEST
Pattern: 0xb Seed: 0xaa
UserDelay: 10
TotalIteration: 20
CurrentIteration: 5
TotalFail: 5
ConsecutiveFail: 5
StartTime: Fri Jul 15 09:11:38 2011
StopTime: Fri Jul 15 09:11:40 2011
Timeout: 0
ErrorCode: 1

And AFTER the repacement:

Port 273 : FAIL
PortType: F PORT                 

PortState: TEST DONE
PortInternalState: INIT                  

PortTypeToTest: NO_TEST
Pattern: 0xb            Seed: 0xaa         

UserDelay: 10
TotalIteration: 20               

CurrentIteration: 5
TotalFail: 5                     

ConsecutiveFail: 5
StartTime: Fri Jul 22 12:45:59 2011
StopTime:  Fri Jul 22 12:46:10 2011
Timeout: 0                       

ErrorCode: 1

Replacing the SFP did fix the issue, the host regained connectivity. But looking at the outputs, the test still comes up with FAIL, even thought the SFP is working and connectivity is restored. The pdf descriding this command doesn't go into much detail about the output.

Can anyone shed some more light on this?

Re: Brocade DCX porttest command

Hi,

the porttest command is sending out packets on the port. These packets have to be sended back from the remote site. This is working on ISL between Brocade switches with some proprietary frames, on an F-Port the porttest is using fcping (Extended link services: ECHO). So, to get a response your Node connected to this port have to support ELS ECHO, if not the porttest will fail.

To check your physical and logical connectivity, you can use switchshow, portshow, nsshow and the commands porterrshow and poprtstatsshow to check the error counter.

Regards,

Jens
