Firmware upgrade/
downgrade
• When upgrading from Fabric OS 5.1.0x to 5.2.0x, if there are two or
more inter-fabric links (IFL) connected to an edge fabric, one IFL will
stay online and the other IFLs will go online and offline. This will cause
a temporary traffic disruption going from multiple IFLs to 1 IFL and then
back to multiple IFLs. This is due to the new front domain consolidation
