Interface Information Reports
The Interface Information report displays traffic volumes over an interface, interface utilization, comparisons between current usage and usage during an earlier time frame, and other information useful for identifying network performance and configuration problems.
Interface Information reports are available from the General Information Reports section of the Reports > All Reports page Built-in tab and also from the right-click menu. When you run the report from the All Reports page, you can use the browse tool to select an interface or enter it manually using the device:interface format.
You can also run the report by right-clicking an interface name or index number. Interface names are available on traffic reports when you select Network Interfaces for the "Report by" criteria on the Reports > Traffic pages. Names and index numbers are also available on the Administration > Devices/Interfaces pages.
Right-click the interface name anywhere it is displayed and choose Interface Information Report. This runs the report for the interface you right-click for the time frame you select from the menu. (If a VXLAN license is enabled, then an Interface Information report for Preferred Interfaces does not use precomputed and cached data.)
The report can include comparisons of information in the specified time frame with the same information in an earlier time frame. Tables list the percentage of increase or decrease from the earlier time frame if data is available.
Report options allow you to save, schedule, print or email the report. You can also change the display units and change the group type by which host groups are reported. more
Section-level options allow you to modify graphical displays, filter tables, and export data. more
The report lists the following information for the specified time frame:
Summary section
-
Interface Information - identifies the interface by its name, type, MTU, speed, and MAC address.
-
Traffic Summary - lists peak traffic, average traffic and percent of capacity utilization for input and output.
-
Interface Groups - If the interface has been assigned to one or more interface groups on the Definitions > Interface Groups page, then the groups it belongs to are listed.
Details section
-
Traffic Volume by Peak % Utilization - Mirror graph showing transmit and receive percent utilization over the selected time frame. Choose Edit Settings from the menu for this section to add Average % Utilization to the display.
Activity section
-
Top Inbound Applications with Ports by Average Bits/s - graphs the traffic volumes of the applications and ports with the top inbound traffic seen on the interface within the specified time frame.
-
Inbound Traffic by Application with Port - lists the average and total inbound traffic volumes of applications and ports seen on the interface.
-
Top Outbound Applications with Ports - graphs the traffic volumes of the applications and ports with the top outbound traffic seen on the interface within the specified time frame.
-
Outbound Traffic by Application with Port - lists the average and total outbound traffic volumes of applications and ports seen on the interface.
Quality of Service (DSCP) section
-
Top Inbound DSCPs by Average Bits/s - graphs the volumes of inbound traffic with the DSCP markings seen most often on the interface.
-
Inbound Traffic by DSCP - lists inbound traffic volumes seen on the interface ordered by DSCP markings.
-
Top Outbound DSCPs by Average Bits/s - graphs the volumes of outbound traffic with the DSCP markings seen most often on the interface.
-
Outbound Traffic by DSCP - lists outbound traffic volumes on the interface ordered by DSCP markings.
Quality of Service (CBQoS Inbound) section
When a Cisco router is configured to send NetProfiler class-based Quality of Service information, this section displays pre-policy and post-policy inbound traffic volumes by the classes defined on the router. more
-
Top Classes by Average Pre-policy Bits/s - graphs the traffic classes that have the most traffic before the router's inbound QoS policies are applied.
-
Top Classes by Average Post-policy Bits/s - graphs the traffic classes that have the most traffic after the router's inbound QoS policies are applied.
-
Top Classes by Average Dropped Bits/s - graphs the traffic classes for which the router's inbound QoS policies have discarded the most incoming traffic.
-
Summary - lists peak and average values for the traffic classes displayed on the graphs. The class names are fully qualified except for the top-level policy names.
Quality of Service (CBQoS Outbound) section
When a Cisco router is configured to send NetProfiler class-based Quality of Service information, this section displays pre-policy and post-policy outbound traffic volumes by the classes defined on the router. more
-
Top Classes by Average Pre-policy Bits/s - graphs the traffic classes that have the most outbound traffic before the router's outbound QoS policies are applied.
-
Top Classes by Average Post-policy Bits/s - graphs the traffic classes that have the most traffic after the router's outbound QoS policies are applied.
-
Top Classes by Average Dropped Bits/s - graphs the traffic classes for which the router's QoS policies have discarded the most outbound traffic.
-
Summary - lists peak and average values for the traffic classes displayed on the graphs. The class names are fully qualified except for the top-level policy names.
Virtual Networks section
-
Top Virtual Networks by Average Bits/s - graphs the traffic volumes of the virtual networks with the top traffic seen on the interface within the specified time frame.
-
Virtual Networks by Average Bits/s - lists the traffic volumes of the virtual networks seen on the interface within the specified time frame.
Conversations section
This section lists the traffic volumes of host pairs and the ports over which they are communicating. The DSCP list column shows all the DSCP markings seen in the conversation between the hosts. This makes it easy to identify interfaces that have multiple DSCP markings.
Event Activity section
-
Alert Level Summary chart – pie chart showing proportions of High, Medium, and Low alerts.
-
Alert Level Summary table – table listing High, Medium, and Low alerts by number and by percent of total.
Notes on alert reporting
The Interface Information Report includes alerts that were triggered by User-defined policies of the Interface Policy type. This includes alerts triggered by Interface Policies that are limited to specific hosts. The Interface Information Report does not include alerts that were triggered by User-defined policies of the Host Policy type, even if the Host Policy was limited to a specific interface. That is, running an Interface Information Report on an interface will not show a Host Policy alert associated with the interface.
Use an Interface Information Report to see alerts triggered by the Interface Policy type of User-defined policy. Use a Host Information Report to see alerts triggered by the Host Policy type of User-defined policy.
