4-6 Advanced Management Settings
This section covers the instructions on how to configure HME-421E/423E’s advanced management
functions.
4-6.1 Port Control
This feature allows the administrator to configure each port’s settings and view the port status.
Port This column is for you to select the port that you want to configure.
This column shows the current port status, and also allows you to enable
State
Negotiation
or disable the port. If the port is disabled, no packet will be transmitted or
received by this port.
This feature allows you to configure the negotiation function to be Auto

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.
When Negotiation column is configured as Force, this column will be
available for you to choose the port link speed.
When Negotiation column is configured as Force, this column will be
available for you to choose the duplex mode of the port.
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.
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 Add ress 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.
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
Ingress Limit Frame
Type
Bandwidth
¾ Broadcast/Multicas t/Flooded Unicast
¾ Broadcast/Multicast
¾ Broadcast o nly
Broadcast/Multicast/Flooded Unicast, Broadcast/Multicast, and
Broadcast only are only for ingress packets. The egress rate only
supports All type.
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.

¾ Ingress: Enter the port effective ingress rate (The default value is
0).
¾ Egress for All: Enter the port effective egress rate (The default
value is 0).
After finishing necessary configurations, click on Apply to save the settings.
4-6.3 Port Mirroring
The feature allows the administrator to monitor and record the traffic of a specific port. The traffic goes in or
out of the monitored ports will be duplicated into the mirror port.
There is only one port can be selected to be destination (mirror) port for
monitoring both RX and TX traffic which come from source ports. Or, use
Destination Port
Source Port
one of two ports for monitoring RX traffic only and the other one for TX
traffic only. The administrator can connect the mirror port to LAN
analyzer.
The port(s) the administrator wants to monitor. All source port(s) traffic
will be copied to the destination (mirror) port. The administrator can
select up to 7 monitor ports in the switch. The administrator can select
multiple source ports by checking the RX or TX boxes.
4-6.4 DHCP Server
DHCP stands for Dynamic Host Configuration Protocol, a protocol for assigning dynamic IP addresses to
devices on a network. With dynamic addressing, a device can have a different IP address every time it
connects to the network. In some systems, the device's IP address can even be changed while it is still
connected. DHCP also supports a mix of static and dynamic IP addresses. Dynamic addressing simplifies
network administration because the software keeps track of IP addresses rather than requiring an
administrator to manage the task. This means that a new computer can be added to a network without the
