OBJECT DESCRIPTION
Port
Use the scroll bar and click on the port number to choose the port to be
configured.
State
Current port state. 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 packets.
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 set 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
Whether or not the receiving node sends feedback to the sending node
is determined by this item. When enabled, once the device exceeds the
input data rate of another device, 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.
Rate Control
(Unit: 128KBbps)
Port-1 - Port-24, supports by-port ingress and egress rate control.
For example, assume port 1 is 10Mbps, users can set its effective egress
rate at 1Mbps and ingress rate at 500Kbps. Device will perform flow
control or backpressure to confine the ingress rate to meet the
specified rate.
•
Ingress: Type the port effective ingress rate.
The valid range is 0 - 8000. The unit is 128K.
0: disable rate control.
1 - 8000: valid rate value
•
Egress: Type the port effective egress rate.
The valid range is 0 - 8000. The unit is 128K.
0: disable rate control.
1 -8000: valid rate value.
Security
A port in security mode will be "locked" without permission of address
learning. Only the incoming packets with SMAC already existing in the
address table can be forwarded normally.
User can disable the port from learning any new MAC addresses, then
use the static MAC addresses screen to define a list of MAC addresses
that can use the secure port. Enter the settings, then click Apply button
to change on this page.
BSF
User can disable/Enable port broadcast storm filtering option by port.
The filter mode and filter packets type can be select in Switch Setting >
Misc Config page.
