Command Usage
• The command map ip tos enables the feature on the switch. The command
map ip tos tos-value cos cos-queue maps IP TOS values to port CoS
queues.
• The precedence for priority mapping is IP Port, IP Precedence/DSCP/TOS,
and default switchport priority.
• This command sets the IP TOS priority for all interfaces.
• IP Precedence, IP DSCP, and IP TOS Priority cannot all be enabled at the
