Orion NPM ver 10.2
My LAN infrastructure consists mainly of 3com switches, mixed models all less than 3yrs old. I use Orion to monitor them and in most respects this is fine however I regularly get orion reporting errors on various interfaces. As a result I then check the interfaces and without fail they report no errors. An example form today is shown below, any body got an explanation? please note it is not restricted to this switch or this model but cisco switches etc are fine.
and from the switch interface directly
