VC provides the ability to monitor server downlink ports, module uplink ports, and stacking links for pause flood conditions:
•If a pause flood condition is detected on a server downlink port, VC can take protective action by disabling the flooded port if pause flood protection is enabled.
•If a pause flood condition is detected on a stacking link or an uplink port, VC only reports that the pause flood condition was detected.
When the pause flood protection feature is enabled, this feature detects pause flood conditions on server downlink ports and disables the port. This feature operates at the physical port level. The port remains disabled until an administrative action is taken. When a pause flood condition is detected on a
The administrative action involves the following steps:
1.Resolve the issue with the NIC on the server causing the continuous pause generation.
This might include updating the NIC firmware and device drivers. For information on firmware updates, see the server support documentation.
Rebooting the server might not clear the pause flood condition if the cause of the pause flood condition is in the NIC firmware. In this case, the server must be completely disconnected from the power source to reset the NIC firmware. To perform a server reboot with power disconnection:
a.Shut down the server.
b.Log in to Onboard Administrator with Administrator privileges using the OA CLI.
c.Enter the command reset server x, where [x=bay number].
d.Confirm that you want to reset the server blade.
