ISL trunk master Port marginal or faulty (switchstatusshow)

Hi all,

 

I have connection 8 ports of ISL (2 trunks @ 32G/trunk) from DCX FOS v6.3.2d to DCX4S v6.2.0c . the ISL and trunk appear properly from trunkshow and islshow.

 

but some how, when i check in DCX4S via switchstatusshow it showing one port is marginal or faulty.

Port 001 is existing Trunk Master to SAN DCX then when I diconnect port 001 then faulty port is move to another port (port 000) which is the new Trunk Master. I have checked the errdump and there is no marginal or faulty port messages

Re: ISL trunk master Port marginal or faulty (switchstatusshow)

Hi,

 

That seem to be related to Fabric Watch configuration. Take a look at FW config on the ports, usually due to incorrect FW thresholds the switch is marked faulty and you have to disable the FW alerts on that port in order to remove the FAULT condition.

 

rgds,

Re: ISL trunk master Port marginal or faulty (switchstatusshow)

what is the portcfgfillword  and you may also try to remove auto neg and enable proper portcfgspeed ...also is it connected to dwdm component ? sometimes the configuration at dwdm line card might cause similar problems.

Re: ISL trunk master Port marginal or faulty (switchstatusshow)

portcfgfillword is default and that port is not connected to dwdm component, the port is connected to DCX (ISL connection).
