data for the ingress interface in bytes of data. This amount can be sent even
if it temporarily increases the bandwidth beyond the allowed limit. This field
is only available if the interface is a port.

Egress Shaping per Queue
In addition to limiting transmission rate per port, which is done in the Bandwidth
page, the device 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 device 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.
