NMIS will learn as much as it can about your network automatically and apply your collection policies to manage all the right things in a node, but sometimes, you want to override what it learns from the devices and tell it other things. This is done using NMIS Node Configurationor nodeconf for short. The intent of the nodeconf is that you do not need to modify the configuration of the actual device itself, you can change how NMIS is going to treat, handle this device by effectively modifying what data comes back from SNMP.
Nodeconf is a very handy capability for operations teams who might not have configuration access to the end node/device.
What Can I Change using Node Configuration
The Node Configuration is able to customise the following properties of a node.
- Override the SNMP sysContact field
- Override the SNMP sysLocation field
- Foreach interface you can configure/override
- Interface Description (ifAlias)
- Interface speed (ifSpeed) and NMIS support asymetric interfaces like ADSL, so you can configure an input speed and and output speed.
- Collection (collect SNMP data or not)
- Events (send events or not)
- Threshold (apply thresholding or not)
Access Node Configuration
You can access node configuration a few ways.
If you are using NMIS 8.5.6G it will be in the Setup Menu as "Node Customisation".
In earlier version of NMIS8 "System -> System Configuration" Menu as "Node Configuration".
With the above two methods you will then need to select the node from the drop down.
In NMIS for a while it is accessible while looking at the node.
Configuring a Node
You will not be looking at a screen with many options and two main columns as below, you can start changing the setting you need to,
