Brocade running v6.3.1_dcb5 connected to upstrem cisco MDS fabric , the fillword is set to mode 3.
Can we igonre these errors? This port is an N port (FROM BLADE chassis switch FC to Cisco FABRIC).
In the case of a few sts_ftb_type2_miss - It is possible that when a device goes offline, the entry will be removed from the ASIC, but the inflight frames from other switches could get dropped. This is similar to unroutable/dest_unreachable frame errors when a port goes offline all of a sudden. It doesn’t indicate a problem so seeing a few of these in the logs is fine.
Does counter increment continuously?
Do you have any issue on the concerned fabric?
Can you provide a portstatsshow of the concerned ports?
