No_Link on a port



I have a port that states it's offline and No_Link.


Here is a small clip from running "portshow". I checked Lr_in & Lr-out. No issues both numbers are equal. However, I get:


Interrupts:        0          Link_failure: 0          Frjt:         0

Unknown:           0          Loss_of_sync: 2238       Fbsy:         0

Lli:               6704       Loss_of_sig:  4466



Loss of sync & Loss of signal numbers. Do they mean something or is this normal? Is it the GBIc?

Re: No_Link on a port

Make sure the Port is Licensed, and enable.


unplug the cable and issue the "portcfgpersistentenable" command.


additional keep in mind, new 8G and 16G Brocade Plattforms required Brocade Genuine SFP.
