Table 6-6. DSLAM-to-IPC Segment

Layer

Solution

Layer 1 ±

If the DSL card shows an alarm, go to screen D-Bto determine the cause.

Physical

An Ethernet alarm usually means no connection to the IPC. Check the

 

cable and make sure the correct type is being used.

 

 

 

On DSLAM, make sure the Ethernet cable is plugged into the port number

 

that corresponds to the slot number of the card.

 

 

Layer 2 ±

If applicable, verify that the desired mode (tagged or untagged) is selected

Network

(screen A-E-A). Reset the card if a change is made.

 

 

 

If tagged mode is enabled on the DSLAM:

 

1.

Make sure a card VNID is configured (Card VNID screen). For each

 

 

connection, the VNID number must be the same as the group number

 

 

on the IPC.

 

2.

Make sure a card VNID is entered (screen A-E-B). If tagged mode is

 

 

disabled for VNID tagging, Card VNID should be none.

 

 

NOTE: With firmware earlier than 3.2.3, follow Steps 3 and 4.

 

 

For firmware later than 3.2.3, complete Step 4 only.

 

3.

Make sure the appropriate VNID is active on the correct port (screen

 

 

A-E-C). An asterisk (*) indicates the active VNID. If tagged mode is

 

 

disabled, none should be active on each port.

 

4.

Make sure the IPC Ethernet port is part of a 802.1q (VNID) group. To

 

 

view VNID groups, enter viqgp.

 

 

 

On the IPC:

 

1.

For VLAN functionality, the mpm.cmd file must contain these lines:

 

 

group_mobility=1

 

 

move_from_def=1

 

 

If necessary, add the lines and reboot the IPC.

 

2.

Make sure that all modules are supported by their respective image

 

 

(.img) files. Enter ls to view file names.

 

3.

Enter gp to make sure the group is configured correctly.
