Configuring VSL QoS
The VSS automatically configures VSL ports for trust CoS, using default CoS mappings (you cannot
change the mappings on VSL ports).
For switching modules that support per-ASIC configuration, the VSL configuration applies to all ports
on the same ASIC (including any non-VSL ports).
The VSS disables the QoS commands on VSL ports (and any non-VSL ports on the same ASIC). For
example, you cannot use QoS queuing or map commands on VSL ports.
To ensure that all eight QoS receive queues are enabled for the 10-Gigabit Ethernet ports on the
supervisor engine, enter the mls qos 10g-only global configuration command.
In Cisco IOS Release 12.2(33)SXI and later releases, when the mls qos 10g-only command is entered
and only one of the two 10-Gigabit Ethernet ports on the supervisor engine is a VSL port, the non-VSL
10-Gigabit Ethernet port can be configured for QoS.
