Customer's rx drops equals their rx overrides. They are having issues with too many drops, which manifests on policy install as the adjacent switches see the link going down. They have 2 1gb interfaces bonded on internal and external. Regarding rx-ovr drops, according to SK33781:
the number of times the receiver hardware was unable to hand received data to a hardware buffer - the internal FIFO buffer of the chip is full, but is still tries to handle incoming traffic ; most likely, the input rate of traffic exceeded the ability of the receiver to handle the data.
Max Power says the best solution here is to bond more interfaces. As they already have 2 bonded interfaces, we are considering 10 gb interfaces. To my question then: does a 10 gb interface have a larger hardware buffer than 2 1 gb bonded interfaces? And my follow up question: do you have numbers on this? These are 13800s with the onboard 1 gb and 10 gb interfaces. This is a big customer and we are in a precarious position on this one and this answer may help decide how we proceed. This is very time sensitive as well. Thank you.
