While working for a case, a question comes up.
The customer reported switch/fabric segmentation while adding new switch to the existing switch/fabric.
The message displayed as shown below, but I can find any info from docs for the incompatible 4 and 5 message.
As there are many different reasons of segmenation, I have checked all conditions, but looks ok except 2 questional points:
1. "switchshow" output indicates zoning : OFF
2. portfillword of each ports by 'portcfgshow" shows 1 switch as "0", and the other switch shows "3".
the message like this:
warning, switch name, port #, Mode incompatible4
warning, switch name, port#, Mode incompatible5
Your tips will be highly appreciated.

Hi jaeil lee,
a Fill Word mismatch is a likely reason for an ISL to fail.
For a 4G link portCfgFillWord should be set to 0 on both sides.
Zoning=OFF means a new switch didn't get zoning configuration from the main fabric which is expected as they were unable to join yet.
Hope this helps,
