http://www.cisco.com/assets/global/DK/pdfs/cisco_virtual_update_-_unified_access_c3850.pdf https://people.ucsc.edu/~warner/buffer.html Seem to support that 3750 has about half the buffers compared to 3850, but double the queues. Even in 3750 enabling 'mls qos' makes things far worse for bursty packets, because you have less buffer for any specific queue, however correctly configured QoS and 3750 outperforms with 'mls qos' compared to without it. I assume 3850 configuration needs some thought too, to best cope with bursty traffic. -- ++ytti _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
