BCM Queue Buffers

Chennai, India

#1 Mar 18, 2010
I am trying to test Egress scheduling in bcm 56502 when one of incoming port(1Gb) is pumped with 200+mbps traffic & outgoing port(1Gb) is configured to output 100mbps (AUTONEG with 100Mbps traffic generator) only.
We expect packet loss here.

But the traffic captured at o/p port doesn't show any drop (final statistics of incoming & outgoing port is same).
Why its like this. Is this depend on the BCM queue buffers that can accomodate rest fo traffic (expected to be dropped).

Tell me when this thread is updated:
