Checking for zoning problems

1. Enter the cfgActvShow command to determine if zoning is enabled.

•

If zoning is enabled, it is possible that the problem is being caused by zoning enforcement
(for example, two devices in different zones cannot detect each other).

•

If zoning is disabled, check the default zone mode by entering the defZone

show

command. If it is no access, change it to all access. To modify default zone mode from no
access to all access, enter the defZone

all command, and then the cfgSave command.

2. Confirm that the specific edge devices that must communicate with each other are in the same

zone.

•

If they are not in the same zone and zoning is enabled, proceed to

step 3
