Hi,

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 " ( .1.3.6.1.2.1.2.2.1.8 ) .

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 :
Equal
NotEqual
Over
Percent Of
Under

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.

Best regards,

Marco
