The only time I've had this problem is when there's a duplexing mismatch or failing autonegotiation between the switch and a device plugged into it. What will happen is the port and device renegotiate on the fly, causing a short-duration outage -- the client may never be aware it happens. If WUG polls during the renegotiation, it will fail.
Check the switch ports -- if you see FCS or alignment errors, this may well be your problem. Hard-code both ends and/or upgrade the NIC driver, it'll solve your problem if autonegotiate is the issue. -----Original Message----- From: Ronald Ward [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 29, 2002 10:08 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: [WhatsUp Forum] monitoring interfaces on a switch. Good question...I'd like to know the answer too. It happens on my 7.03 WUG too and I've to turned off the monitoring of interfaces because of it.

Sometimes, the switch icon shows service down(some interfaces are not responding) even though the devices connected to interfaces going down are still fine. Could you explain why WUG shows false status of interfaces on a switch? Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
