Hi Expert,
*Catalyst 6500 Release 12.2SXH *
SERVER-|-ACCESS-Router---L2-link---1g----------|

If i configure priority Queue which can take 100% BW, so it means priority
traffic from different Access-Router aggregated to 100% of uplink of
Aggregation switch to Core roure , all other traffic including control plane
will be dropped. Is there is any work around for this. I can only do
hardware-switched QoS.
6500 QoS
http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/qos.html
6500 QoS Note from above URL
For hardware-switched traffic, PFC QoS does not support the bandwidth,
priority, queue-limit, or random-detect policy map class commands. You can
configure these commands because they can be used for software-switched
traffic.
Does it mean that i need to disable mls switching to do the harware based
swithing. I cant do the software based switching because that will not be
good for the heavy traffic load considering my network, which may put hugh
CPU load on my 6500 aggregation box.
Regards,
Dave
