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
1
Log in to the NFM-P main server station as the nsp user.
2
Navigate to the /opt/nsp/nfmp/server/nms/config directory.
3
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.
4
Add the following line to the end of the file:
<customMTURefresh refresh="true"/>
5
Save and close the nms-server.xml file.
6
Open a console window.
7
Navigate to the /opt/nsp/nfmp/server/nms/bin directory.
8
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.
9
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.
