Port states in BrocadeDifferences between port states, reported when execute the switchshow command (online, offline, no light, not sync, etc...). I noticed that sometimes a particular is disable and its state show "no light" and other time its state says "not sync". Why?Online/In_SyncNormal operating port with a connected device / ISL to other switch. "Online" is the operating state, "In_Sync" the physical state of the receiver/transmitter. (to see the in_sync you have to issue a portshow, switchshow doesn't display it) No_Module no gbic/sfp insertedNo_Light gbic/sfp inserted, maybe even cable connected, but receiving no lightDisabled/OfflineIf you disable a port (via portdisable) its operating state goes to offline. Fabric OS doesn't check offline ports, this means the physical port state is nt display as whatever it was If there was a device previously connected it displays as disabled/in_sync, if there was none it displays as disabled/no_light (or no_module). This physical state is only updated when you enable the port again.swFCPortPhyState: noCard(1), noGbic(2), laserFault(3), noLight(4), noSync(5), inSync(6), portFault(7), diagFault(8), lockRef(9)swFCPortOpStatus: unknown(0), online(1), offline(2), testing(3), faulty(4)Port State in switchshow DescriptionNo_Card No interface card presentNo_Module No module (SFP or other) presentNo_Light Module not receiving lightNo_Sync Module receiving light but out of syncIn_Sync Module receiving light and in syncLaser_Flt Module signaling a laser faultPort_Flt Port marked faultyDiag_Flt Port failed diagnosticsLock_Ref Locking to the reference signalTesting Running diagnosticsOnline Port is up and running
