Hi,
This is a pppoe-client on Atom C2000 based Axiomtek NA361 Hardware.
pppoe is running via VLAN on device em5, which is I354 based:
em5: flags=28843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,NOINET6> mtu 1500
lladdr 00:60:e0:5a:75:39
priority: 0
media: Ethernet autoselect (1000baseT full-duplex,rxpause,txpause)
status: active
# ifconfig vlan7
vlan7: flags=28843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,NOINET6> mtu 1500
lladdr 00:60:e0:5a:75:39
priority: 0
vlan: 7 parent interface: em5
groups: vlan
status: active
# ifconfig pppoe0
pppoe0: flags=28810<POINTOPOINT,SIMPLEX,MULTICAST,NOINET6> mtu 1492
priority: 0
dev: vlan7 state: initial
sid: 0x0 PADI retries: 0 PADR retries: 0
groups: pppoe egress
status: no carrier
inet 0.0.0.0 --> 0.0.0.1 netmask 0xffffffff
The pppoe server side has a MAC of 00:30:88:1f:18:9a and the client em5 is
00:60:e0:5a:75:39
Here, the client asks for the server via broadcast:
20:59:34.771668 00:60:e0:5a:75:39 (oui Unknown) > Broadcast, ethertype 802.1Q
(0x8100),\
length 60: vlan 7, p 3, ethertype PPPoE D, PPPoE PADI [Service-Name] \
[Host-Uniq 0x3DCA3906]
The server responds:
20:59:34.800113 00:30:88:1f:18:9a (oui Unknown) > 00:60:e0:5a:75:39 (oui
Unknown),\
ethertype 802.1Q (0x8100), length 87: vlan 7, p 6, ethertype PPPoE D,\
PPPoE PADO [Host-Uniq 0x3DCA3906] [AC-Name
„FFMR71-se800-B2224180702381“]\
[AC-Cookie „..lvg}..Bv.>.;8."] [Service-Name]
The client’s answer is going to 00:30:75:39:00:30 instead of 00:30:88:1f:18:9a:
20:59:34.800121 00:60:e0:5a:75:39 (oui Unknown) > 00:30:75:39:00:30 (oui
Unknown),\
ethertype 802.1Q (0x8100), length 60: vlan 7, p 3, ethertype PPPoE D, \
PPPoE PADR [Service-Name] [AC-Cookie „..lvg}..Bv.>.;8."] [Host-Uniq
0x3DCA3906]
This is the bug.
An example of a working negotiation (another obsd client, with other hardware,
00:80:c8:c9:7f:e0, same server):
