Configuring Quality of Service Configuring QoS - General 20 STEP 4 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. STEP 5 Click Apply. The bandwidth settings are written to the Running Configuration file. Configuring Egress Shaping per Queue In addition to limiting transmission rate per port, which is done in the Bandwidth page, the switch can limit the transmission rate of selected egressing frames on a per-queue per-port basis. Egress rate limiting is performed by shaping the output load. The switch limits all frames except for management frames. Any frames that are not limited are ignored in the rate calculations, meaning that their size is not included in the limit total. Per-queue Egress rate shaping can be disabled. To define egress shaping per queue: STEP 1 Click Quality of Service > General > Egress Shaping per Queue. The Egress Shaping Per Queue page is displayed. The Egress Shaping Per Queue page displays the rate limit and burst size for each queue. STEP 2 Select an interface type (Port or LAG), and click Go. The list of Ports/LAGs is displayed.
