Port Controls
Change the port status
Select the port by scroll the list in
Port
column
State:
Current port status. The port can be set to disable or enable mode. If the
port state is set as ‘Disable’, it will not receive or transmit any packet.
Negotiation:
Auto and Force. Being set as Auto, the speed and duplex mode are
negotiated automatically. When you set it as Force, you have to assign the speed
and duplex mode manually.
Speed:
It is available for selecting when the Negotiation column is set as Force.
When the Negotiation column is set as Auto, this column is read only.
Duplex:
It is available for selecting when the Negotiation column is set as Force.
When the Negotiation column is set as Auto, this column is read only.
Flow Control:
Set flow control function as Enable or Disable. When enabled,
once the device exceed the input data rate of another device as a result the
receiving device will send a PAUSE frame which halts the transmission of the
sender for a specified period of time. When disabled, the receiving device will drop
the packet if too much to process.
Back Pressure:
Set Back Pressure as
ON
or
OFF
in Half Duplex mode.
Band Width:
All ports support port ingress and egress rate control. For example,
assume the wire speed of port 1 is 100Mbps; users can set its effective egress
rate as 2Mbps, ingress rate as 1Mbps. The switch will perform Flow Control or
Back Pressure to confine the ingress rate to meet the specified rate.
¾
In:
Key in the port effective ingress rate. The valid range is from 0 ~ 999. 0
means rate control is disabled.
¾
Out:
Key in the port effective egress rate. The valid range is from 0 ~ 999. 0
means rate control is disabled.
Priority:
The static priority is based on port. If the port is set as high priority,
income frames from the port always are high priority frame.
Security:
When the port is in security mode, the port will be “locked” without
permission of address learning. Only the incoming packets with static MAC
already existing in the address table can be forwarded normally. User can disable
the port from learning any new MAC addresses, and then use the static MAC
