I am curious as to the status of your issue. I have similar
issues in a larger environment and assumed that it was related to the network
size. Do the mac addresses show in the mac address table of your host device?
Also, what snmp version are you running ?
We actually made this change in our environment - Moved UDT devices from an additional poller over to our primary poller (very low polling/reduced traffic). We did not install NPM 11.0.1 Hotfix4 in our production environment because when we tested it in our dev environment
it did not make a difference.
>1. Missing endpoint information from an active port. This is not on every port, probably very few but still not accurate.
We found the reason why certain devices are not displayed even though they have a persistent connection onto a port.
The devices are those that go into "sleep" mode such as printers and wyse terminals. We are using a work-around by adding those devices
(since they are always connected to the same port) as a node in NPM and having it poll the device which in turn causes UDT to show its
connections - mac and ip addresses and hostname (if it's in dns).
>2. Endpoint changing IP address via DHCP - seeing a 2-3 hr lag where both IP's are listed (duplicate device) for the port.
We still do not have a solution for the 2/3 hour lag time when a connection changes its ip addess.
Note: I noticed that there are new hotfixes available that pertain to UDT that may help.
