FAQ-What Are the Common Troubleshooting Methods of DAA Problems on an ME60?

Issue Description

What are the common troubleshooting methods of DAA problems on an ME60?


The troubleshooting methods of DAA problems are as follows:

DAA does not take effect:

1. Check whether a license is loaded and whether the license contains DSG. The display license command output is as follows:

LME0SSGF01  Function  YES  DSG Function


2. Check whether the accounting-service-policy daa command is run globally.

3. Check whether the rate limit configuration is correct and whether the qos-profile and flow-queue-shaping configurations are performed.

4. Check whether the user group is configured correctly. If not, a route distribution failure may occur.

5. Check whether the traffic-separate enable command is run for the policy template. If the basic bandwidth is 10 Mbit/s and the internal network bandwidth is 50 Mbit/s, the actual maximum rate is 10 Mbit/s with the traffic-separate enable command not run.


Accounting problems:

1. If a customer wants no accounting on the internal network, run the tariff-level-cfg 1 accounting off command to disable accounting.

2. If the accounting together command is run, an accounting stop packet of the value-added service is sent upon user logout even if the level-1 accounting is disabled.

3. If the customer is concerned about whether DAA packets are sent by a device, run the trace command. The focus is on the accounting ID. An accounting ID example is as follows:

[Acct-Session-Id(44)] [34] [WLMQ-D00000SSG000004ae5756000081]

Here, SSG000004 indicates a level-5 accounting packet.



Key configurations:

value-added-service policy a000 daa

accounting-scheme acct1

user-group pppoe

traffic-separate enable

tariff-level 1 qos-profile 100M

tariff-level 1 flow-queue-shaping inbound 100000 outbound 100000

tariff-level-cfg 1 accounting off

tariff-level 2 qos-profile 10M

tariff-level 2 flow-queue-shaping inbound 10000 outbound 10000


Important query commands:

1. Check whether the value-added service is generated.

<BAS-CDLGDX-ME60-X16>display value-added-service user user-id 233741


User access index           : 233741

State                       : Used

User name                   : ~ghca95A3BB68E3035058ab7e5a28606b17afCD02885201

User service number         : 2

COPS server name            : --


The used VAS service id table are:

(233741,    1)  (233741,    2)----If the two items are contained in the command output, the value-added service is generated.



2. Locate the DAA service.

[ME60-1-diag]display vas global


gulNpsSynPosition                       : 0

g_ulVSMIfSmooth                         : 0

g_ucVSMIfLocalAcctEnable                : 0

g_ulVSML4SKIP                           : 0

g_usSigGroup                            : 0

g_ulVsmVasEnable                        : 1-----Whether the value-added service is enabled.

g_ulVsmSynFlow                          : 0

g_ulVsmlicenable                        : 1-----Whether the license is loaded.

g_ulVsmFunEnable                        : 0

g_ulVsmFlowEnable                       : 0

g_ulVsmUsedFlowNum                      : 0

g_ulFlowQueryTimeLen                    : 2

g_ulVsmMultiSerEnable                   : 0


3. Check whether the test traffic is about the DAA service.

[BAS-Home]display value-added-service user user-id 20890 daa tariff-level 1


Daa user service table:


Service user id                              : 20890
