or Force. When Auto, the switch will auto-negotiate the speed and the
duplex mode with the connected port. When Force, the administrator will
have to manually configure the speed in the Speed column and the
duplex mode in Duplex column to match with the connected port.
Speed
When Negotiation column is configured as Force, this column will be
available for you to choose the port link speed.
Duplex
When Negotiation column is configured as Force, this column will be
available for you to choose the duplex mode of the port.
Flow Control
This feature allows the administrator to select flow control options. When
Disable, the receiving device will drop the packet if there is too much to
process. When Enable, 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.
Security
This feature allows the administrator to configure the security level for
managing this switch. If the security column is configured as On, the port
will accept only the first MAC address entry in Static MAC Address table
to access this switch and change the switch settings. If the security
column is configured as Off, any MAC address can access the switch
and change the switch settings.
4-6.2 Rate Limiting
This feature allows the administrator to set up every port’s bandwidth rate and packet limitation type.
Ingress Limit Frame
Type
This feature allows the administrator to select the packet type that needs
to be filtered for a certain port. The packet types available for selecting
include:
¾ All
¾ Broadcast/Multicast/Flooded Unicast
¾ Broadcast/Multicast
¾ Broadcast only
Broadcast/Multicast/Flooded Unicast, Broadcast/Multicast, and
Broadcast only are only for ingress packets. The egress rate only
supports All type.
Bandwidth
All ports support port ingress and egress rate control. For example, if port
1 runs at 10Mbps, the administrator can set its effective egress rate as
1Mbps, and ingress rate is 500Kbps. The switch performs the ingress
rate by packet counter to meet the specified rate.
