Hi,
Problem: StackWise Port is Flapping
These conditions might cause StackWise port flapping:
An unreliable or intermittent (bad) connection between a StackWise cable connector and the
switch stack port connector
.A defective StackWise cable
.A defective StackWise interface on a switch
When one or more StackWise ports are flapping, the source of the problem is probably an
unreliable connection between a StackWise cable and a StackWise switch port.
If you suspect StackWise port flapping, first verify that the retainer screws are
adequately tightened and fully seated against the connector shell. Make sure both retainer
screws are tightened the same amount. In some cases you need to disconnect and reconnect
the cable while you are troubleshooting, but do not test the connection unless the
retainer screws are firmly holding the connector.
You will also find good info on how Stack manager works on this platform.
I would suggest you to replace the stack cables and let me know the results.
Hope this helps.
Cheers
Somu
