addition, query the learning of the MAC address of the PC on the MA5600. The information is
displayed as follows:

It is found that the fault occurs because the modem of the A company is a single-PVC modem
and the modem learns PVC 8/46 with the VLAN 19 tag by mistake.
4. By the careful analysis of the networking before and after the cutover, it is found that before
the cutover, the E8-2 services with the VLAN 19 tag of different MA5600 devices are
terminated on different ports of the BAS; after the cutover, the E8-2 services with the VLAN 19
tag of all the MA5600 devices are terminated on the same port of the BAS within one broadcast
domain. On any port of any MA5600, after the modem of the A company receives the PADI
packets with the VLAN 19 tag from other MA5600 devices, the PVC automatic search function
is enabled, and it is determined that the PVC of the modem of the A company is PVC 8/46. The
modem of the A company is a single-PVC modem, so when the PVC is determined to be PVC
8/46, other PVCs (including PVC 0/35 for Internet access through dialup) are deactivated by the
modem. In this case, the 678 error occurs when the user connected to the modem of the A
company goes online through dialup.
5. There are four ways to solve the problem:
1) Replace the single-PVC modem of the A company with the multi-PVC modem.
2) Delete PVC 8/46 on the DSLAM device. The modems that do not provide the E8-2 services
are in the bridge mode, so only PVC 0/35 is needed for the dialup.
3). Enable the port isolation on the S7802 to prevent the broadcast.
4). Re-plan the data, and ensure that the E8-2 management VLAN 19 of each DSLAM device is
labeled with the service VLAN to prevent the broadcast.

iption:
Networking: modem ? MA5600 ? S6506 ? CISCO BAS
Dual PVCs (0.35) and dual services (Internet access and IPTV) are configured on the ADSL port of
the MA5600. On the S6506 and BAS, the corresponding data is configured. The Internet access
service and IPTV service adopt the dialup mode, using two types of accounts respectively.
When the common modem providing a single Ethernet port is used, sometimes error 691 is
displayed and sometimes the service is normal. When the modem providing four Ethernet ports is
used, the service is always normal.
