Add/Edit an Interface Filter

Roles can be pre-configured to use Active Monitors when conditions you select match or evaluate to true. You can filter on operational state, administrative state, regular expression matches, and much more.

Important: While Active Interface Monitor Filters help to identify which roles warrant a particular monitor, Role Monitor Apply Rules (Apply Always, Check Support) have a deciding influence.

Filter Groups

Single or combined filter groups can be used. For example, you can simply filter on any combination of two operational states (let's say Operationally up and Administratively down) within a single group. Or, for example, you could use that criteria in combination with another group, let's say Interface Type, where Interface Type equals Fast Ethernet or Ethernet. Values within groups are ORed together (any can be true) but if you have more than one group, group expressions evaluate together as ANDs (criteria for each group must be true to be considered a match).

Available Filter Group...	Applies Filters
Operational Status	Match a single or any of the selected operating states.
Interface Type	Look for the SNMP MIB ifType value as defined by https://www.iana.org/assignments/ianaiftype-mib/ianaiftype-mib.
Port Index	Match the physical port position on the device.
Interface Speed	Network interface speed. (This value is typically the nominal speed of the network interface.)
Regular Expression	Match all or a substring of the derived or configured interface name or description.

Example

WhatsUp Gold interprets the following Monitor Filter and delegates monitors to:

Given the condition that any device's status (in this case detected Operational Status) has an operational status of "link up" (Operationally up)...
Delegate monitoring to any of the selected Interface Types (Ethernet, Fast Ethernet, Gigabit Ethernet)
