The Traffic Statistics panel displays traffic statistics for each interface on the Screen. The following table describes the fields on the Traffic Statistics panel of the Statistics tab. The values displayed in these fields cannot be modified.

Table 9-8 Controls on the Traffic Statistics Panel of the Statistics Page


Control	Description
Interface field	Name of the interface.
Address field	Address of the interface.
Inputs field	Total number of packets seen on that network interface. This number includes packets processed by the Screen and intranet traffic. Because this counter records more than just the number of packets through the interface, the number can be much higher than the sum of the numbers in the Passes and Drops fields, which record the number of packets passed and dropped.
Outputs field	Total number of packets passed from other interfaces on the Screen and sent out over this interface.
Passes field	Number of packets received from another interface, matched to an ALLOW rule exactly, and sent out over the designated interface.
Logs field	Number of packets that have been logged by the Screen according to the actions in the active configuration.
Alerts field	Number of SNMP alerts generated because of the traffic on this network interface.
Drops field	Number of packets that have been dropped, either as a result of exactly matching a DENY rule or as a result of not matching any rule and being dropped as the default action of the Screen's interface.
AllocFail field	Error counter for packets lost because of the lack of resources.
NoCanPuts field	Error counter for packets lost because of the lack of stream flow control.
BadPackets field	Error counter for packets lost because of errors.

The SKIP Statistics panel shows the SKIP statistics for the SunScreen. The following table describes the fields on the SKIP Statistics panel of the Statistics page. The values displayed in these fields cannot be modified.

Table 9-9 Controls on the SKIP Statistics Panel of the Statistics Tab
