pppoe terminating every few minutes__ urgent

Hi ,
every few minutes, the customers getting disconnected. Cant find anything in logs. No error nothing.

Can anyone help how to debug? This is causing major failures in network and customers are crying.
A small error comes but that for every connection

<1f65>: rcvd proto=0x8057 01 01 00 0e 01 0a b1 8b…
<1f65>: received unsupported protocol 0x8057

In the logs , how can i filter log for particular mac ? Pl resond..

Open a terminal window and do:

/log print where message~"xx:xx:xx:xx:xx:xx"

it doesnst give anything. After a sec, prompt comes back

If it doesn’t find anything, then there are no log entries with that MAC.

You can also enter partial MAC addresses:

/log print where message~"00:0C:42"

Theses are logs
09:17:28 pppoe,ppp,info : disconnected
09:17:39 pppoe,info PPPoE connection established from 64:70:02:4D:B1:7D
09:17:39 pppoe,ppp,info : waiting for call…
09:17:40 pppoe,ppp,info : terminating… - user sunildesai authentica
tion failed
09:17:40 pppoe,ppp,info : disconnected
09:17:52 pppoe,info PPPoE connection established from 64:70:02:4D:B1:7D
09:17:52 pppoe,ppp,info : waiting for call…
09:17:53 pppoe,ppp,info : terminating… - user sunildesai authentica
tion failed
09:17:53 pppoe,ppp,info : disconnected


But if i do

[admin@K - MT] /log> /log print where message~“64:70:02”
Immediately the prompt comes back

[admin@K - MT] /log>

Hm… that’s a new one on me. The command works for me in v3, 4, and 5. What version are you running?

Try running this instead, maybe it will work:

:foreach i in=[/log find message~"64:70:02"] do={
	:put [/log get $i];
}
