CommittedAccessRate configuration case and details

Case requirements: 1. all www traffic must be sent, and the ip priority of the traffic that complies with the first rate-side policy in the web is set to 5. If the traffic does not comply with the policy, the ipprecedence is set to 0 (best-effort transmission ). 2. Set the ipprecedence of ftp traffic following the second rate policy to 5. If the ftp traffic exceeds the rate policy, throw the packet. 3. The remaining traffic is limited to 8 Mb,

CaseRequirements:

1. all www traffic must be sent, and the ip priority of the traffic that complies with the first rate-side policy in the web is set to 5. If the traffic does not comply with the policy, the ipprecedence is set to 0 (best-effort transmission ).

2. Set the ftp traffic to 5 According to the ip precedence of the second rate policy. If the ftp traffic exceeds the rate policy, throw the packet.

3. The remaining traffic is limited to 8 Mb, the normal burst size is 16000 bytes, and the maximum burst size is 24000 bytes. The traffic compliant with the policy is set to 5, and the excess traffic is thrown into the package.

Conditions and actions:

What are the conditions for compliance?

When the data to be sent is smaller than normal (bc.

Maximum Condition?

The data to be sent is larger than the normal burst, and smaller than the maximum burst (be)

What are the violation conditions?

When the data to be sent is larger than the maximum burst (be), it is deemed as a violation.

Action:

Discard/transfer/mark and transfer.

// This sentence is really long. When I first came into contact, I was still depressed for a long time when I saw such a long string of things. Haha. Output refers to the output traffic. 101 indicates the access list label and 200000000 indicates the guaranteed access rate. The value ranges from 8000 to 2000000000 bits per second. 24000 is a normal burst. Its value should be 1000-512000000byte, and 32000 is the maximum burst. Its value range is 2000-10241000000bytes.conform-action, which specifies the action when the condition is followed, the action specified after the exceed-action is beyond the limit. For details about the action, I will talk about it later.
