Interfaces

The Administration > Devices/Interfaces page Interface tab displays information about each interface of the data source devices with which the NetProfiler can communicate.

Click a column title to sort the list by a column.

Use the search feature to locate particular devices by name, IP address or address range in CIDR format. Performing a search restricts the content of the page to the specified host name, IP address or address range.

Options menu – The Options menu offers the following features:

  • Delete Silent Interfaces   more

  • Export Interfaces – exports the list of interfaces in comma-separated-value text format to a file on your local system.

  • Import Interfaces   more

If NetProfiler is receiving data from more than 5000 interfaces, a Show all Devices and Interfaces button is displayed instead of this tab. Click the button to display this tab. It may require several minutes to display a very large list of interfaces and their descriptive information.

The Interfaces table displays:

  • Status - Color represents status, as described in the legend.

  • Device Address

  • Device host name

  • Index - the interface index on the device

  • Name (ifDescr) - assigned on the data source device

  • Label - Alphanumeric characters, dots, forward slashes, dashes, and underscores. Must contain at least one non-digit character. Must be unique within each Device Address space.

  • Description (ifAlias) - This is assigned on the data source device, but it can be overridden locally.

  • ifAlias (Override) - You can assign your own name to an interface and then add the Description column to interface reports to make tracking easier. The appliance displays up to 65 characters.

  • Sampling Rate - If the data source is sending sampled data, the sampling rate tells NetProfiler how to multiply the sampled data counts. If the data source is not using a recognized sampling specification, then NetProfiler may not detect the sampling rate. This column shows either the detected sampling rate or "undetected."

  • Sampling Rate Override - If the detected sampling rate is not valid for the data source, or if no sampling rate is received or detected, you can specify a sampling rate for the data source so that NetProfiler can adjust counts to reflect the sampling rate.

  • MAC - the MAC address of the interface

  • Type - The type of interface hardware (e.g., Ethernet CSMA/CD RFC3635).

  • Type Description  

  • MTU - maximum transmission unit

  • Inbound Speed (bps)

  • Inbound Speed Override (bps)

  • Outbound Speed (bps)

  • Outbound Speed Override (bps)

Note on speeds: NetProfiler determines speeds based on ifSpeed and ifHighSpeed in the MIB of the data source device. If the value of ifSpeed is valid (that is, the data source device returned the value with the expected type for the OID) and non-zero and not UNIT_MAX (4294967295), NetProfiler uses it as the speed. If this is not what NetProfiler receives, then, if ifHighSpeed is valid, NetProfiler uses ifHighSpeed * 1000000 as the speed. If neither ifSpeed nor ifHighSpeed return valid values, NetProfiler displays the speed as 0. If NetProfiler cannot obtain the speeds but you know what they are, you can override the speed values.

  • Inbound Traffic (bps)

  • Outbound Traffic (bps)

  • Inbound Utilization - percent of the device speed that NetProfiler currently sees being used

  • Outbound Utilization - percent of the device speed that NetProfiler currently sees being used

Note:  Some information and features associated with physical interfaces are not available for virtual interfaces in an Amazon Web Services Virtual Private Cloud. See AWS VPC device and interface reporting limitations.
