When a new service is added to an ME60, PPPoE dialup fails, but the original PPPoE users on the ME60 function properly. The configuration of the new interface is confirmed to be the same as that of the original service interface. The key configuration of the PPPoE user access interface is as follows:
interface
GigabitEthernet2/1/3.2629
pppoe-server bind Virtual-Template 1
description PPPOE_AoLin_OLT_XX.XX.XX.XX
user-vlan 1000 4000 qinq 2629
bas
#
access-type layer2-subscriber default-domain authentication pppoe
access-limit 2 start-vlan 1000 end-vlan 4000 qinq 2629
1. Collect the configuration file on the live network. Check that the configuration of the new interface is confirmed to be the same as that of the original service interface.
2. On the ME60, trace terminal access.
[LN-ME60]trace enable
[LN-ME60]trace access-user object 1 mac-add 2089-842E interface GigabitEthernet
2/1/3.2629
The tracing information shows that the PPPoE session stage is not complete and packet exchanges exist. After the ME60 receives a PADI packet from the client, the ME60 replies with a PADO packet. The client then initiates a PADR packet request again. After that, no PADS packets are sent. Instead, error information is printed as follows.

info:

[trace info: Find

3. Check that the inner VLAN 1001 of the user is within the configuration scope and the outer VLAN 2629.
4. Use the MAC address to check the user. It is found that the MAC address has been used for user login.
<LN-ME60-6>dis access-user mac-address 2089-842E-XXXX

It can be confirmed that the user's MAC address is already online and resides
on interface 2/0/0. The inner label is 1014 and the outer label is 2621, which
is inconsistent with the VLAN information and information about the interface
from where the new user goes online. Therefore, the user fails to go online,
and a tracing error is displayed.
5. Perform a test after the user is logged out from the ME60. The test succeeds.
Check whether a user with the same MAC address has already gone online from the ME60. If so, log out this user and then try again.
