Hi,
Does anyone has a procedure or guideline about how to perform a loopback test in a Brocade FC switch?
I have been reading the manuals and have seen commands such as spinfab, portloobacktest, but it is not very clear to me how they work...
I would like to generate traffic in a port, put a loopback plug in the other end of the fibre and see it errors are generated. Connecting a plug I have been able to test the link, but without traffic...
Is there a way to set an ISL port in 'loopback mode' and make some testing from the remote switch?
Any suggestion is highly appreciated,
Felipon

Hi, in FOS 7 and 16Gbps ports have the D-Port that you can use to test an ISL between two switches.

Hi Guldmyr,
I have read about that feature in FOS 7, but my switchs are running FOS 6.4.2a.
Thanks

For testing ISL links, I'd recommend spinfab. It is made to test ISLs. Here is a quick example testing E_Port 11:
porttest could also be used, even while the E_Port is still up. Another example on the same port (then monitoring with 'porttestshow'):
bro:admin> porttest -ports 11
bro:admin> porttestshow -ports 11
Port 11 : UNKNOWN
PortType: E PORT PortState: TESTING
PortInternalState: TX PortTypeToTest: ALL_PORTS
Pattern: 0xb Seed: 0xaa UserDelay: 10
TotalIteration: 20 CurrentIteration: 3
TotalFail: 0 ConsecutiveFail: 0
StartTime: Wed Mar 21 21:43:04 2012
StopTime: NONE
Timeout: 0 ErrorCode: 0

Thank you Jaymike3,
I think that that will do.
