Device Settings

Device List

This page allows you to check the status of a known device and override the interface descriptions and speeds obtained from it.

The name and address of each known device is listed, along with an icon indicating its status; an exclamation () indicates that the device could not be contacted using SNMP or it is being ignored due to a licence violation and an hourglass () indicates that the device is currently being scanned and cannot be edited. You can update the list to see if a scan has finished by clicking “Refresh”. If no icon is displayed the device is working correctly.

Clicking the name of the device you wish to edit will open a new page. It is important to remember that any changes you make to any device are only applied when you click “Ok” in the main device settings page.

Device Settings

The settings page for a single device allows you set to set its SNMP version and community and to override properties obtained using SNMP.

General Settings

In the General Settings box you can override the name detected using SNMP and the default “Show interface descriptions” Report Settings value for the device. You can choose to archive old real-time data for the device rather than delete it by checking “Archive real-time data”. See Archiving for more information.

SNMP Settings

If the device does not support SNMP you can change the SNMP mode to “Don’t use SNMP”. This will assign default properties to each interface encountered in NetFlow exports from the device. It is also possible to freeze a device’s configuration by changing the mode to “Keep current configuration” – this will cause any new interface encountered to be ignored, so should be used with caution. If possible you should allow NetFlow Tracker to use SNMP to scan a device as the numbers used to identify the inbound and outbound interfaces in NetFlow exports are not constant and SNMP is the only way NetFlow Tracker can work out a correct correlation between an identifiers and physical interface or port.

You can request an immediate rescan of an SNMP device by clicking “Rescan”. This will scan the device using the SNMP version and community specified in the page but will not save them; you must click “Ok” on the main device settings page before any changes are applied. Note that NetFlow Tracker rescans a device when it is restarted, if a new interface is encountered or if it appears the device was rebooted, so you will not normally have to manually rescan a device.

BGP Settings

The local AS number is required to get correct AS numbers for traffic routed to or from the local AS in a BGP environment; if you do not use BGP this value should be left blank.

Some devices are able to send both the peer and origin AS number for each NetFlow record; for these devices you will have the option to choose which AS numbers are stored in the database.
