You can add LACP/ECMP ports/paths to reduce the chance that packets need to be buffered so long that the buffer becomes full. To use a dirty word, flow-control might be an option as well. However, you need to carefully test the particular switch and software to see if it works with any sanity. Also remember that flow-control is likely to effectively cause HoL blocking on a port transmitting a lot of traffic toward another port that is busy, and other ports which aren't. For example, you would not want to send flow-control to a 10GE storage server's port that is transmitting to any 1GE ports because it would likely be harmful to storage performance for all connected hosts, whenever just one host's port is full. I personally think that the complexity, buggyness, and potential gotchas of flow-control far out-weigh the small potential gains. -- Jeff S Wheeler <[email protected]> Sr Network Operator / Innovative Network Concepts _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
