In UDT, if you click on a port it will display data under "Port Details". One of those pieces of data is the "Port Description".
The port description is also displayed when you click on a Node and go to List Resources (NPM).
If the port description changes AFTER the node has been discovered, NPM will update the port description during the next polling cycle.
However, in UDT the port description doesn't get polled again unless you rediscover the node completely. This means that UDT and NPM have conflicting data, which is confusing and not needed. Having to rediscover nodes for this to be updated in a large environment by setting up a bunch of discoveries is pretty unreasonable as a work around.
The UDT requested feature is for the Port Description to be updated during each UDT polling cycle.
