At the risk of asking an opinion question, are there any guidelines/practices that specify a threshold where the number of pause frames indicates a problem?
The ratio of transmitted pause frames to received frames is about 3%. If I assume xon/xoff, that's really about 1.5% of received packets are generating pauses.
I'm trying to figure out if I have a serious over-subscription problem.
Hardware is Nexus 2232pp, linked to a 5000. Flow control is the default settings (transmit on).
