Information

 
TitleLink flaps continuously on X460-G2
Symptoms
The 10G ports of X460-G2 platform are flapping continuously while there is egress congestion. 
The same issue was not observed on other 10G ports platform.
Environment
  • X460-G2
  • EXOS 22.5.1.7
  • link flap 
Cause
It looks like the flaps occurs only from EXOS 22.5.1.7 and this is due to the SDK changes made in EXOS 22.5.
 
Resolution
Upgrade to the fixed release when it is available.
This is fixed by CR xos0073360
  • EXOS 22.7.1
  • EXOS 22.5.1-patch1-9
  • Currently there is no GA version available for 22.6 that includes this fix.

As a workaround you can also configure a 150ms debounce timer on the links with the command:

 "configure ports [<port-list>] debounce time [default | <milliseconds>]"

Or if the 10Gb port is used for stacking, use the following command:

"configure stack-ports [<stacking-port-list>] debounce time [default | <milliseconds>]"
