QFX3500 QoS provisioning breaks connectivity in TOR configuration

[ibaldin]

When used in mishmash rack the QFX3500 in TOR configuration does not properly pass TCP and UDP packets (ICMP is fine). Possibly a rate configuration on the policer, as removing the filter off the VLAN fixes the problem.

• On QFX3500 switch, the policer is configured with minimum values (8k for bandwidth limit and 512 bytes for burst-size-limit).

policer orca_policy_2201-policer { if-exceeding { bandwidth-limit 8k; burst-size-limit 512; } then discard; }

• When bandwidth is changed on Flukes to 100Mbps, the same values were applied on the switch.
• On the logs the values are seen as below. QUANTUM_MAX_RATE changes according to the selection on Flukes. (And I think QUANTUM_BURST_SIZE also changes according to the bandwidth selected.)
  The first line -bw=0 burst=0- is the same on RCI rack as well (no matter what bandwidth value is selected).

• CreateQoSVLAN.txt is identical to QFX hierarch as well.

Should fix this in mishmash first, then re-test DD performance.
