Crital error: PPPoE server on Bridge

RouterOS General
1

Hi,

I have a mikrotik PPPoE server (RB1100AHx2, ROS v5.20), running on a bridge. The bridge has several (50+) EoIP channel ports.
Working fine, but if I disable one of EoIP channels, and enable some seconds later, all pppoe users are disconnecting from PPPoE server and making a new connection.
I can repeat this test all of my pppoe servers, and i have some error.
It’s look like a software bug in ROS v5.20 (i haven’t got older than 5.20 server).
Any idea?

Try to set auto-mac=no and admin-mac on bridge.

Yes, I tested it. not work, but I see something interest here:

[admin@PPPoE-core-07] > interface bridge print  
Flags: X - disabled, R - running 
 0  R name="EoIP-core-bridge" mtu=1500 l2mtu=65535 arp=enabled 
      mac-address=00:00:5E:FF:FF:07 protocol-mode=none priority=0x8000 
      auto-mac=yes admin-mac=00:00:5E:FF:FF:07 max-message-age=20s 
      forward-delay=15s transmit-hold-count=6 ageing-time=5m

How can ‘auto-mac=yes’ is set if I grant MAC address manually? Every time when I used this option, i seen ‘auto-mac=no’.
I’ll test it late at night, too many users online now on every servers.

ps: How can I delete duplicated topics?

if you set mac address from winbox it automatically changes auto-mac=no. If you set mac address from terminal then auto-mac=no must be set manually.

Thanks, I’ll test it. I don’t remember how i set this, i’m using winbox and ssh mixed, what’s simpler.

In winbox on bridge interface just add Admin MAC address.

I tried set admin-mac manually, and set auto-mac=no, and it’s work, problem solved.
Maybe i forget set ‘auto-mac’ in ssh session (through winbox this is automatic), and not checked before..
Thanks for the trick!

, regards
