Class - Supermicro SSE-G2252 User Manual

class

This command defines a traffic classification upon which a policy can act, and enters
Policy Map Class configuration mode. Use the no form to delete a class map.
Syntax
[no] class class-map-name
class-map-name - Name of the class map. (Range: 1-16 characters)
Default Setting
None
Command Mode
Policy Map Configuration
Command Usage
• Use the policy-map
configuration mode. Then use the class command to enter Policy Map Class
configuration mode. And finally, use the set command and one of the police
commands to specify the match criteria, where the:
• set phb command sets the per-hop behavior value in matching packets. (This
modifies packet priority for internal processing only.)
• set cos command sets the class of service value in matching packets.
(This modifies packet priority in the VLAN tag.)
• set ip dscp
(This modifies packet priority in the IP header.)
• police commands define parameters such as the maximum throughput, burst
rate, and response to non-conforming traffic.
• Up to 16 classes can be included in a policy map.
Example
This example creates a policy called "rd-policy," uses the class command to specify the
previously defined "rd-class," uses the
incoming packets will receive, and then uses the
average bandwidth to 100,000 Kbps, the burst rate to 4,000 bytes, and configure the
response to drop any violating packets.
