4.6.5.85 <FC [ON/OFF] [N1-4]> Command
This command enables and disables IEEE 802.3x flow control on LAN ports.
4.6.5.86 <IRATE [speed/OFF] [N1-4]> Command
The command IRATE is an abridgement of the Ingress Rate. It limits the incoming data stream
that reaches the internal Hardware Ethernet Switch. The IRATE can be set up for every LAN port
separately.
IRATE command counts all arriving traffic without discrimination between ingress VLAN numbers
and QoS settings. It means that IRATE command should be used when the LAN port is set to
ACCESS mode, so all traffic will be processed by the internal switch with selectable VLAN and
QoS settings. If incoming traffic has bigger bandwidth then selected by IRATE command, the
excess will be dropped if Flow Control is disabled on the port, or the switch will send so called
“MAC Pause Frame” if the Flow Control is enabled.
In general it is possible to use IRATE command if LAN port is set to TRUNK or to MIXED mode.
IRATE command will limit the whole incoming bandwidth without taking into account VLAN tags
and priorities inside incoming traffic. In that case a network will work without QoS support but with
bandwidth control.
• IRATE [rate] [N]: Sets the desired rate limit.
• IRATE OFF [N]: Disable rate limiting.
The parameter [rate] is expressed in kbits or Mbits, for example:
IRATE 128K 1 - will set 128 kbps limit on LAN1
IRATE 256 2 - will set 256 kbps limit on LAN2
IRATE 1M 3 - will set 1000 kbps limit on LAN3
