Create MEP circuits

The circuits with more than two end nodes are called as Multi End Point (MEP) circuits. The MEP circuits can be created only for OTN for this release. Perform the following steps to create Multi-End Points (MEP) circuit:

Go to Configuration > Layer 1 > Create Circuit menu and click P2P/MEP Circuit option. Create Circuit page is displayed.
Select or enter the desired values under Common Circuit Info by referring to the table Attributes of Create Circuit - MEP.
Enter the options for Source Information. For more information, refer table Attributes of Create Circuit - MEP.
1. To select the time slot, click M. The available and unavailable timeslot information will be displayed.
2. Do one of the following for selecting the time slots:
  > Manually: Under CHANNELS, click the desired channel number(s) and click Add Channel. The channels(s) will be displayed under Selected CHANNELS. Click Apply.
  
  > Automatically: Click Auto button. Depending on the Capacity, the required number of channels will automatically get listed under Selected CHANNELS. Click Apply.
3. The selected channel(s) will now be displayed in TimeSlot field on Create Circuit window.
4. If user desires to add protection to the source port or source node, click Add source client port protection or Add source node protection link respectively and select the Port and TimeSlot as done in Step 3a to 3c.
Under Destination Information section, enter value for the desired parameters referring to table Attributes of Create Circuit - MEP. Refer Step 3 for selecting the time slot.
Click Start Route Creation. The Create Circuit page is displayed.
The following figure shows the graphical view of created MEP circuit:

Attributes of Create Circuit - MEP

Attribute	Description

Create Circuit
Circuit Type	Select the type of circuit as 'MEP'.
Sub Type	The 'OTN Circuit' will be selected by default. This parameter is not configurable.
Circuit name	Enter the name of the circuit.
Customer	Enter the name of the customer. The drop-down list will be displayed after entering the character in the field.

Source Information
SrcTrafficType	Allows the user to select the source and destination traffic pattern from the options: OTN SONET/SDH ETH FC
Node	Enter the source node name. On entering a letter, the list pertaining to that letter will be displayed. NOTE: On selecting the option IP, you can enter the IP instead of the node name.
Port	Select the desired port from drop down menu.
Time slot	Click M (Select TimeSlots) to select the timeslot on the desired port.
NOTE: The Add source client port protection option enables you to protect the source port on same source node. The Add source node protection option enables you to protect the source port on different node.
Destination Information
DestTrafficType	Allows the user to select the source and destination traffic pattern from the options: OTN SONET/SDH ETH FC
Node	Enter the destination node name. On entering a letter, the list pertaining to that letter will be displayed. NOTE: On selecting the option IP, you can enter the IP instead of the node name.
Port	Select the desired port drop down menu.
Time slot	Click M (Select TimeSlots) to select the timeslot on the desired port.
