Flushes on a POS interface

[phillipediab]

Hi,

I am getting a lot of flushes on a POS interface. Can someone tell me why i am seeing these flushes and how can I fix the problem.

thanks

I think Flushes or overrun error occurs on a POS(Packet over SONET) because the input rate may be exceeding the receiver's ability to handle the data.This means that the other side of the connection sends the data faster than the receiving controller could process it. One solution would be to rate-limit the TX traffic on the remote end or change the connection to a higher speed interface.If it is a backup link for any GigE card, then try moving that card to someother Bus
