Configuring Bandwidth

The Bandwidth page enables network managers to define two sets of values, Ingress Rate Limit and Egress Shaping Rate, that determine how much traffic the system can receive and send.

The ingress rate limit is the number of bits per second that can be received from the ingress interface. Excess bandwidth above this limit is discarded.

The following values are entered for egress shaping:

To enter bandwidth limitation:

  1. Click Quality of Service > General > Bandwidth. The Bandwidth page opens.
  2. The Bandwidth page displays bandwidth information for each interface.

    The % column is the ingress rate limit for the port divided by the total port bandwidth.

  3. Select an interface, and click Edit. The Edit Bandwidth page opens.
  4. Select the Port or LAG interface.
  5. Enter the fields for the selected interface:
    • Ingress Rate Limit--Select to enable the ingress rate limit, which is defined in the field below.
    • Ingress Rate Limit--Enter the maximum amount of bandwidth allowed on the interface.

    NOTE     The two Ingress Rate Limit fields do not appear when the interface type is LAG.

    • Egress Shaping Rate--Select to enable egress shaping on the interface.
    • Committed Information Rate (CIR)--Enter the maximum bandwidth for the egress interface.
    • Committed Burst Size (CBS)--Enter the maximum burst size of data for the egress interface in bytes of data. This amount can be sent even if it temporarily increases the bandwidth beyond the allowed limit.
  6. Click Apply. The bandwidth settings are modified, and the Running Configuration file is updated.
