The Home User Rate Limit Does Not Take Effect Due to Incorrect Configuration

Publication Date:  2013-09-30 Views:  35 Downloads:  0
Issue Description
Version:
ME60V600R005C00SPC700
Networking:
User-----ME60-----publicnetwork
Symptom:
Intheinbounddirection,theratelimitfortheuseraccessinterfaceontheME60is1Mbit/s.However,theactualuploadratefortheuserisabove2Mbit/s.Accordingtothesymptom,theratelimitdoesnottakeeffect.
Handling Process

Query the actual rate. The rate is above 2 Mbit/s.

2. Analyze the user configuration.
The user access interface is configured with the qos-profile rate limit, which indicates that the user is a home userr. The qos-profile limits the total rate on the interface of the home user. If the qos-profile is configured in the domain, the CAR in the qos-profile is used for service level rate limit.

The "session-group-excludecarinbound" is configured, indicating that the CAR does not work in the ingress direction. Therefore, the inbound rate is not limited.
Root Cause
Configuration error results in the exclusion of users from the CAR.
Solution
Delete the "session-group-excludecarinbound" configuration.
Suggestions
The ME60 works in multiple scenarios and has multiple rate limiting methods. The configuration on the ME60 must be performed based on the actual conditions. When problem occurs, you must check the configuration and exclude the configuration error first.
