Cause 1- Check the mac-address table on UA5000 ethernet port, there were no BRAS mac-address in th
Analysis: e PPP VLAN 362 and 985
2- Check the mac-address table on lan switch, there were no BRAS mac-address in the PPP VLA
N 362 and 985
3- Check the log on the BRAS, PADI from VLAN 362 and 985 had been received, and PADO ha
d been sent from the BRAS
Obviously the PADO didn't hit the lan switch, because the source mac-address of PADO is the B
RAS mac-address, if the PADO hit the lan switch, absolutely the lan switch can learn the BRAS
mac-address
Data section checked the IP/MPLS network and the BRAS mac-addresses came back.
Handling Check the IP/MPLS network to find out where the PADO lost

Keywords: AMPB, video phone, erratic display
Digest: AMPB, video phone, erratic display
Phenomenon
The host is IPMA. For details on the networking, see the attachment.
Description: Two video terminals, phone 1 and phone 2, are connected to two ADSL terminals respectively,
which are connected to the upstream NE20 router through the APMB board. The services of the
router go upstream to the IP network, to which video terminal phone 3 is connected directly.
Phone 1 and phone 3 can communicate with each other successfully and the video display is
smooth. Phone 2 and phone 3 can also communicate with each other successfully. The
communication between phone 1 and phone 2, however, is abnormal. The screen usually freezes
and erratic display occurs.
Alarm Error 678 is prompted during the dialup of all broadband subscribers.
Information:
Cause
The possible causes may be:
Analysis: 1. The communication between the users of the same board is abnormal.
2. The configuration of IPMA is improper, which causes abnormal communication between the
two users of IPMA.
3. The upstream ports of the users are not consistent.
4. The forwarding of the upper layer NE20 router is abnormal.
