I'm setting up a SNMP monitoring of a firewall. In particular I need to generate an alert if a ethernet interface link goes Down and if it comes back to Up.
I'm using the standard MIB " .iso.org.dod.internet.mgmt.mib-2.interfaces.ifTable.ifEntry.ifOperStatus " ( .18.104.22.168.22.214.171.124.1.8 ) .
The problem is that this Mib object returns a Integer value (1=Up;2=Down;3=Testing).
The Alarm Operator, for Integer values, can be one ot the following :EqualNotEqualOverPercent OfUnder
In this case these operators are not useful... is it possible to check, as for String values, for Changes of the returned values ?
If not... is it possible to obtain the enumerated string value, rappresented by the integer value ?
Thank you very much in advance.
