Cisco Firewall Net Event Interface

1.3.6.1.4.1.9.9.147.1.1.2.2.1.2

The interface most closely associated with this event. For example, for an event that relates to the receipt of a packet, this object identifies the interface on which the packet was received. If there are multiple interfaces associated with an event, the interface most closely associated with the cause of the event will be used. For example, for an event for the setup of a TCP connection, the interface on the initiator's side of the connection would be preferred. If there is no associated interface, then this object has the value zero.
