Jumbo Frame Support

Jumbo Frames are not an approved standard Ethernet frame size, so you must ensure that all of your networking equipment can support these frames to prevent them from being dropped. The GS748T switch can carry a maximum frame size of 10240 bytes.

1.From the main Navigation Pane menu, select: Switch → Advanced → Jumbo Frame; The Jumbo Frame Setting page is displayed.

2.Select Enable or Disable on this page and click Apply.

Controlling Per-port Packet Throughput

The Rate Limit Setting enables you to determine the bandwidth of the selected port. There are 11 options of data rate in the range 512K bps to 1000M bps with a disable option that applies no limit to the data rate. Ingress and egress rates are separately configurable. The Egress Rate settings is available only with v3h1 firmware.
