Hi Alex,

The command is hidden, as far as I know because it is not supported and
replaced by "table-maps". If you press enter after "platform qos map" it
will say incomplete command, so it's still there but hidden.

You could use the "table-map" command instead and "show table-map" to
verify the config. Details in the guide below:
http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/15.0SY/configuration/guide/qos_global_and_if.html

Best regards,
Andras
