    The Interface Bandwidth Allocation Report displays bandwidth resource information for configured interfaces. The information displayed includes:

    • Interface Name: Indicates the name of the interface.
    • Physical Bandwidth: Indicates the maximum throughput potential based on the physical connection of the interface.
    • Configured Bandwidth: Indicates the maximum throughput configured for the interface.
    • Total Configured Guaranteed Bandwidth: Indicates the guaranteed throughput configured for the interface.
    • Total Allocated Guaranteed Bandwidth: Indicates the guaranteed throughput allocated for the interface.
    • Total Utilized Bandwidth: Indicates the bandwidth consumed by the interface in transmitted traffic.


High-end ScreenOS devices:

The following devices are referred to as high-end devices:

  • NetScreen-ISG 1000
  • NetScreen-ISG 2000
  • NetScreen-5200
  • NetScreen-5400

All other ScreenOS devices are referred to as lower-end devices.

With high-end ScreenOS devices, you can monitor the Bandwidth information for physical interfaces, sub interfaces, and aggregate interfaces. The maximum Egress bandwidth can be configured on the interface.

Note: The bandwidth is measured in Kilo, Mega, or Giga bits per second. You can also click Refresh to update the bandwidth resource statistics.


Lower-end ScreenOS devices:

On lower-end devices, you can monitor the Bandwidth information for physical interfaces, sub interfaces, and tunnel interfaces. The maximum Ingress and Egress bandwidth can be separately configured on the interface. You can monitor the interface bandwidth by using the following command in the CLI:
