MA5200F uses trace and trace aim is username. Trace user PPPOE dial and online/offline, but cannot receive any information.
1. Check trace aim with display trace object and trace is used.
2. After user dials and check user’s online information with display access-user command. Trace username and online user are consistent.
3. Check username of PC terminal. PC terminal does not contain domain name. Trace username is changed as the format without domain name. And then it can obtain information.
When MA5200F traces PPPOE username, it retrieves username from PPP packet and estimates whether it needs record or not. If user dials without domain name, it will match default domain of portvlan. Information at the device is user’s full information with domain name. For trace, it needs configure the same username as client port and then trace online information of users. If client does not enter domain name but adds default domain, there will be no information.
Besides, trace username and entered one are not consistent. If user is not in authentication period, user fails at PPPoE discovery period, trace it and there is no information. It is better to port + VLAN or enable trace according to MAC address.
