[Description]
Specifies remarking operations for bandwidth classes Yellow and Red that were classified by individual policers. In addition,
reassign the egress queue according to the egress queue ID table that corresponds to the trust mode.
For remarking, you can select either CoS value, TOS precedence, or DSCP value.
If this is executed with the "no" syntax, the remarking setting is deleted.
In order to perform remarking, you must specify this command and additionally use the police command (policy map class
mode)) to specify "remark" as the action for the corresponding bandwidth class.
[Note]
In order to execute this command, QoS must be enabled.
Remarking can be used in conjunction with pre-marking and specifying the egress queue.
Up to four user-defined values may be used for pre-marking/remarking to a DSCP value not recommended in the RFC. The
following table shows the DSCP values that are recommended in the RFC.

[Syntax]
aggregate-police name
no aggregate-police name
[Parameter]
name : Name of aggregate policer (maximum 20 characters; uppercase and lowercase are distinguished)
[Input mode]
global configuration mode
[Description]
Generates an aggregate policer. If the policer has already been generated, this command edits its content.
When the command succeeds, you transition to aggregate policer mode, where you can edit the content of the aggregate policer.
If this command is executed with the "no" syntax, the aggregate policer is deleted.
In the following case, the content of the aggregate policer cannot be changed (you will not transition to aggregate policer
mode).
