policy map class mode
[Description]
Specifies individual policers (twin rate) for the categorized traffic classes.
If the setting was already made by the police command, its content is changed.
Metering on the SWR2311P is implemented as a single-rate three-color marker (RFC2697), and the following processing can
be specified for the categorized bandwidth classes.
• Green : Only forward (cannot be specified)
• Yellow : Choose forward, discard, or remark
• Red : Choose discard or remark
However, remarking can be specified for either Yellow or Red, not both.
Detailed remarking settings are made using the remark-map command (policy map class mode). Regardless of whether action
is set to "remark," remarking is disabled if there are no detailed remarking settings for that bandwidth class. In this case, the
default settings (Yellow: forward, Red: discard) are applied.
If this is executed with the "no" syntax, metering/policing/remarking processing is deleted.
This cannot be used in conjunction with the aggregate policer (police-aggregate command).
[Note]
In order to execute this command, QoS must be enabled.
[Example]
Make the following settings for received frames of LAN port #1
• Permit traffic from the 10.1.0.0 network
• Categorize bandwidth classes as CIR:48kbps, PIR:96kbps, CBS:12kbyte, and PBS:12kbyte
• Green: forward, Yellow: rewrite DSCP value to 10, Red: discard
