To configure a 7705 SAR MW link member

Purpose

Perform this procedure to configure a 7705 SAR MW link member on the 7705 SAR-8 or 7705 SAR-18. To support an MW link and an MW link member, the NE must be configured with 4 × MWA Gig Ethernet (2 TX, 2 SFP) + 4 × Gig Ethernet SFP daughter cards. See To configure an MDA for information about how to configure daughter cards.

If you configured 1+1 HSB protection in To configure a 7705 SAR MW link , you can configure a main radio and a spare radio for each MW link. By default, the main radio assumes the active status and the spare radio assumes the standby status.

If you configured 1+1 HSB protection and you want to revert back to 1+0 protection, you must delete the spare radio. You cannot delete the main radio.

1+1 HSB protection is displayed on the NFM-P physical topology map. The protection state is shown on the links, and 1+1 links are grouped in a common link group. The expansion of links on the physical map displays eight links. See Topology map types for more information about the NFM-P physical topology maps.

Steps
 
1 

Choose Network→NE→Shelf→Card Slot n→Daughter Card Slot n→Port n/n/n where the port object is the port that you need to use for the MW link.

Note: Only the first four ports on the MDA are microwave-aware.

If a port is associated with an MW link, the port cannot be used as a timing reference. Also, if a port is already being used as a timing reference, the port cannot be associated with an MW link member.

2 

Right-click on a port and choose Properties. The Physical Port (Edit) form opens.

3 

Configure the Encapsulation Type parameter to be Dot1 Q.

4 

Configure the Mode parameter.

Note: Setting the Mode parameter to Access allows you to later associate the MW link with an L2 or L3 access interface for services. Setting the Mode parameter to Access is the typical setting. Setting the parameter to Network allows you to associate the MW link with a network interface.

1+1 HSB radio protection can only be configured on a port in Network mode.

5 

Click OK and confirm to close the form.

6 

Create an MW link member:

  1. If you configured 1+0 radio protection in To configure a 7705 SAR MW link , right-click on the MW link you created and choose Create MW Link Member. The Create MW Link Member step form opens.

  2. If you configured 1+1 HSB radio protection in To configure a 7705 SAR MW link , right-click on the MW link you created and choose Create MW Link Main Radio. The Create MW Link Member step form opens.

7 

Configure the required parameters on the Specify the Member Properties form.

The Database Filename parameter must be the same name as the database file in the config file of the cflash directory and must be in a *.tar format.

8 

Click Next. The Select Ports form opens.

9 

Choose the port from the list and click Finish. Only eligible ports are displayed in the list and only one port per link is supported.

To configure a main radio, you must choose a port in an odd numbered slot.

10 

Select the View the newly created Port Termination check box if you need to view the MW link member properties, and click Close.

11 

To configure a spare radio, right-click on the MW link where you created the main radio, and choose Create MW Link Spare Radio. Repeat Step 7 to Step 10 .

To configure a spare radio, you must choose a port in an even numbered slot.

12 

Click on the Radio tab. The tab displays information about MPT hardware and the software state of the connected radio. You can enable PM statistics for G.826, ACM, and Power. Enable the checkboxes as required.

13 

Associate the MW link with an L2/L3 access interface or a network interface, if required.

  1. If you set the MW Link Member port Mode to Access in Step 4 , you can associate the MW link with a service, if required.

    The MW links can be used in the L2 Access Interfaces of the following service types:

    The MW links can also be used in the L3 Access Interfaces of the following service types:

    The created access interface appears in the list on the L2 Access Interface or L3 Access Interface tab of the MW Link (Edit) form, as appropriate.

    See the specific service chapter and forms when you create the required L2 or L3 access interfaces. Specify the MW Link Member as the Terminating Port.

  2. If you set the MW Link Member port Mode setting to Network in Step 4 , the Network Interface tab is displayed. Click on the tab and then the Create button to create a network interface. The network interface that you create appears in the list. See To create an L3 network interface on a routing instance for more information.

14 

Click on the Statistics tab to view radio analog statistical information, if required.

15 

Click on the Faults tab to view alarm information, if required.

16 

To modify the MW Link Member properties, right-click on the MW link member and choose Properties. The MW Link Member (Edit) form appears with the General tab displayed.

17 

Configure the required parameters.

18 

Save and close the form.
