Restrictions for Marking Network Traffic
The following restrictions apply to the following packet marking action:
• Only explicit marking is supported for policer-based marking.
Multi-attribute Marking Support
The supervisor engine can mark more than one QoS attribute of a packet matching a class of traffic. For
example, DSCP, and CoS can all be set together, using either explicit or tablemap-based marking.
Note When using unconditional explicit marking of multiple fields or policer-based multi-field, multi-region
(conform/exceed/violate) marking the number of table maps that can be setup in TOS or COS marking
tables will be less than the maximum supported.
