- Followed KB where it says that special characters should not be used in zone configuration.
- Even after removing the special characters from zone configuration ISL ports are still disabled with same error.
- NPIV is enabled on ISL ports of both switches.
- Tried to disable and enable the ISL ports on both switches, but still no luck.
- Login to the switch as
rootuser and ran the commandzone stateshowto see how many Enhanced Zone Objects are present in the G620 switch, the output still shows 8 as below.

- Since G620 switch had originally 8 zones with hyphen (-) in them, tried to delete one of the 8 zones disruptively and observed if
cmitis reduced to 7, but issue still persists.
