Hi,

please send us the configuration you are using to see why it is not working.

Gernerally speaking policing works on both directions for PFC QoS on 6500; the only case where it works in one direction only is when you try to police on SVI in a purely L2 setup.

I have L2 PORT and that port want to restric the bandwitdh. here is configuration of L2 PORT. Please guide me which configuration can help.

I have check on internet after converting port L3 both direction work but how can i configure existing config without affecting existing network setup.

Please provide me step by step detail of both direction restriction.

Hi,

policers on L2 ports (per-port policers) will work only in input direction.

check

http://www.cisco.com/en/US/partner/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/qos.html#wp1720400

"Note Policers can act on ingress traffic per-port or per-VLAN. For egress traffic, the policers can act per-VLAN only."

If you need bi-directional policers you need to apply the policers on the SVI.

If there is none you need to create it (interface vlan150) and apply the service policies to it.

By the default policies work in per-port mode; if you need per-vlan mode you need to add mls qos vlan-based
  to the physical ports belonging to vlan 150 (Gi2/42 in your case plus all the trunks which carry that vlan and all other access ports in that vlan).

Also, don't forget that if you have DFC's on your chassis policing will be implemented indipendently by each engine (the PFC and DFC), meaning that each engine will police at 512K in that vlan on its own (hence higher might be achieved).

All this other info is on the same guide I gave you in other sections.

I am not able to see this give link. but when i apply service policy command input and output direction packet is not being transmit over physical interface and connectivity broken.

Can you provide me configuration steps of bandwidth restriction on physical interface.
