Port Basic Settings
Jumbo Frame
The maximum Transmission Payload or MTU is typically 1500 bytes, in case the user requires even a bigger MTU length for a
specific scenario, there is an option on the GWN780x(P) Switch to enable Jumbo Frame, the maximum Ethernet frame size
ranges from 1518 up to 10000.
Jumbo Frame
Flow Statistics
For monitoring or even sometimes troubleshooting, the Flow Statistics displays in real time the flow of data with different
units like Octects, Packets, Transmission Rate and OurErrPackets. The option to clear all the statistics or a specific port is
supported as well.
Description
It is used to configure the information description of this interface , which can be a description of usage, etc., with a
maximum of 128 characters, and the characters limited to input are numbers 0-9 , letters az / AZ and special
characters.
Port Enable
Set whether to enable the interface.
it is enabled by default.
Speed
Set the rate of the interface, the options are {Auto, 10Mbps, 100Mbps, 1000Mbps}.
The default is auto-negotiation.
Note: When set to Auto, the rate of the interface is automatically negotiated between the interface and the peer port
.
Duplex Mode
Set the duplex mode of the interface. The GE ports options are { auto-negotiation, full-duplex, half-duplex}.
The default is auto-negotiation.
Note: Optical ports only support full-duplex mode.
● Auto-negotiation: The duplex state of an interface is determined by the auto-negotiation between the interface
and the peer port.
● Duplex: the interface send and receive data packets.
● Half-duplex: interface can only send/ receive packets.
Flow Control
Set the flow control on the interface, the options are {Disabled, Enabled, Auto}. The default is Disabled.
After enabling it, if the local device is congested, it will send a message to the peer device to notify the peer device
to temporarily stop sending packets, after receiving the message, the peer device will temporarily stop sending
packets to the local and vice versa. Thus, the occurrence of packet loss is avoided.
Note: The optical port does not support auto-negotiation mode.
