Step 11: If you are using Gigabit Ethernet cards supported in VSS mode on Cisco Catalyst 6500 Supervisor

Engine 2T based switches, configure an additional QoS policy for the Gigabit Ethernet ports.

A separate egress QoS policy is configured to accommodate the Gigabit Ethernet cards which use a 1P3Q8T

queuing architecture. This policy does not apply to the Cisco Catalyst 6880-X platforms.
