OperationallyDown alert

I am running on LMS 2.5 and DFM configure to alert using email. Somehow one of the switch keeps showing the alert 00001HL: saying that a port connected to another switch is OperationallyDown. Infact, everything seems normal and when i check the syslog i did not see any port status down.

i am running on the following IOS c3560-ipbase-mz.122-25.SEB2.bin.

Anyone got idea what is going on??

Re: OperationallyDown alert

Sometimes, when the switch does not respond to DFM's SNMP poll, DFM will change the port status to unknown, and create an alert that the port is Operationally Down.

One way to work around this is to increase your polling interval (make it less frequent), increase your SNMP timeout and retry setting.

At other times, it could be an IOS bug also.
