|---|---|
Id |
Report ID, that is, number of collected flows. You can run the display forward-path report command to view detailed information about inbound and outbound interfaces according to the specified report ID. The IDs are displayed according to the sequence in which the collect forward-path command was executed. If an ID is deleted, the existing IDs remain unchanged. The ID configured later is displayed in the position of the deleted ID. For example, IDs 1 and 2 exist on the device. If ID 1 is deleted, ID 2 remains unchanged. If the collect forward-path command is used, the new ID is displayed in the position of deleted ID 1. The device can collect inbound and outbound interfaces and traffic information of a maximum of 8 flows. |
