To configure the NFM-P to retain non-default port MTU values

Before you begin

The MTU value for a port is associated with the port mode, such as access or network, and the port encapsulation type. If you change the mode or encapsulation type of a port, the MTU value changes to the associated default. If you do not want the port MTU values to change, you can use this procedure to configure the NFM-P to retain each port MTU value, regardless of a mode or encapsulation type change.

Note: You must perform this procedure on each main server in a redundant NFM-P deployment.

Steps
 

Log in to the NFM-P main server station as the nsp user.


Navigate to the /opt/nsp/nfmp/server/nms/config directory.

CAUTION

Service Disruption

Contact your Nokia technical support representative before you attempt to modify the nms-server.xml file. Modifying the nms-server.xml file can have serious consequences that can include service disruption.

Open the nms-server.xml file using a plain-text editor.


Add the following line to the end of the file:

<customMTURefresh refresh="true"/>

Save and close the nms-server.xml file.


Open a console window.


Navigate to the /opt/nsp/nfmp/server/nms/bin directory.


If the main server is a standalone server, or the primary server in a redundant deployment, enter the following:

bash$ ./nmsserver.bash read_config ↵

The main server reads the nms-server.xml file and puts the configuration change into effect.


If the main server is the standby server in a redundant deployment, enter the following:

bash$ ./nmsserver.bash force_restart ↵

The main server restarts and puts the configuration change into effect.

Close the console window.
