3-30 Configuring Pseudowire Services MPW-1 MP-4100 Ver. 2.0
³ To select the timeslots connected to the pseudowire:
1. Navigate to the Configuration > Applications > Multi-Service over PSN > PW >
Service Parameters screen of the desired pseudowire.
2. After selecting the prescribed internal DS1 port, select Time Slots.
3. Initially, the screen is empty. Select Add to add the desired number of
timeslot selection fields.
4. Sequentially select each timeslot selection field, and enter the number of the
prescribed timeslot.
5. When done, save the selections by typing s.
6. The selected timeslots are listed now in a single row, and a new item, Delete
Range, appears. This item enables to delete the current selections: type the
desired numbers in the format displayed on the screen and then confirm.
Configuring Fault Propagation for MPW-1 Modules
The fault propagation function can be used to notify equipment at a far end port
that a fault condition has been detected at a local port.
MPW-1 modules support unidirectional fault propagation for pseudowires: if a
problem is detected on a pseudowire, the attached physical port receives a fault
indication.
Fault propagation cannot be enabled for ports with redundancy enabled.
For the supervision terminal, use Configuration > System > Fault Propagation (for
instructions, refer to the
Megaplex-4100 Installation and Operation Manual ).
³ To configure fault propagation:
1. On the Configuration > System menu, select Fault Propagation, and then
press <Enter>.
2. Select Fault Propagation to toggle the selection: to configure fault
propagation, select ENABLE.
3. Select Interfaces to display the interface configuration screen. If no interfaces
has yet been mapped for fault propagation, the screen is empty.
4. To add fault propagation between a new pair of interfaces, type A (Add) and
then press <Enter>.
You will see the Interface configuration data form.
5. Select the first endpoint, Slot A: you will see a submenu which lists I/O slots
in which modules with ports that support fault propagation are installed, or
at least programmed. For pseudowires, select None.
6. Select the desired pseudowire index number for Slot A.
7. After selecting the desired pseudowire, repeat the selections for the physical
endpoint (Slot B and Port B) of the pseudowire.
8. After specifying the two endpoints, select the fault propagation direction by
means of the Mode field. The only selection valid for pseudowires is
UniDirectional(A- > B): fault conditions are reported only from endpoint A
(the selected pseudowire) to endpoint B.
