The destination IP network or host mask, in number of bits (prefix length). It defines how
much of a network address that must match, in order to qualify for this route. Valid values
are between 0 and 32 bits respectively 128 for IPv6 routes. Only a default route will have a
mask length of 0 (as it will match anything).

NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean
Time (GMT). If use the NTP mode and select a built-in NTP time server or manually specify an
user-defined NTP server as well as Time Zone, the switch will sync the time in a short after
pressing <Apply> button. Though it synchronizes the time automatically, NTP does not update
the time periodically without user’s processing.
Time Zone is an offset time off GMT. You have to select the time zone first and then perform
time sync via NTP because the switch will combine this time zone offset and updated NTP time
to come out the local time, otherwise, you will not able to get the correct time. The switch
supports configurable time zone from –12 to +13 step 1 hour.
Default Time zone: +8 Hrs.

The log is a standard for logging program messages . It allows separation of the software that
generates messages from the system that stores them and the software that reports and
analyzes them. It can be used as well a generalized informational, analysis and debugging
messages. It is supported by a wide variety of devices and receivers across multiple platforms.

Figure2-1.10: The System Log configuration
Parameter description:
Server Mode :
Indicate the server mode operation. When the mode operation is enabled, the
syslog message will send out to syslog server. The syslog protocol is based on
UDP communication and received on UDP port 514 and the syslog server will not
send acknowledgments back sender since UDP is a connectionless protocol and it
does not provide acknowledgments. The syslog packet will always send out even
if the syslog server does not exist. Possible modes are:

2-2 Green Ethernet
EEE is a power saving option that reduces the power usage when there is low or no traffic
utilization.
EEE works by powering down circuits when there is no traffic. When a port gets data to be
transmitted all circuits are powered up. The time it takes to power up the circuits is named
wakeup time. The default wakeup time is 17 us for 1Gbit links and 30 us for other link speeds.
EEE devices must agree upon the value of the wakeup time in order to make sure that both the
receiving and transmitting device has all circuits powered up when traffic is transmitted. The
devices can exchange wakeup time information using the LLDP protocol.
EEE works for ports in auto-negotiation mode, where the port is negotiated to either 1G or 100
Mbit full duplex mode.
For ports that are not EEE-capable the corresponding EEE checkboxes are grayed out and

thus impossible to enable EEE for.
When a port is powered down for saving power, outgoing traffic is stored in a buffer until the
port is powered up again. Because there are some overhead in turning the port down and up,
more power can be saved if the traffic can be buffered up until a large burst of traffic can be
transmitted. Buffering traffic will give some latency in the traffic.

Parameter description:
Optimize EEE for
The switch can be set to optimize EEE for either best power saving or least traffic
latency.
Port:
The switch port number of the logical port.
ActiPHY :
Link down power savings enabled.
ActiPHY works by lowering the power for a port when there is no link. The port is
power up for short moment in order to determine if cable is inserted.

PerfectReach :
Cable length power savings enabled.
PerfectReach works by determining the cable length and lowering the power for
ports with short cables.
EEE :
Controls whether EEE is enabled for this switch port.
For maximizing power savings, the circuit isn't started at once transmit data is
ready for a port, but is instead queued until a burst of data is ready to be
transmitted. This will give some traffic latency.
If desired it is possible to minimize the latency for specific frames, by mapping the
frames to a specific queue (done with QOS), and then mark the queue as an
urgent queue. When an urgent queue gets data to be transmitted, the circuits will
be powered up at once and the latency will be reduced to the wakeup time.

The current link state is displayed graphically. Green indicates the link is up and
red that it is down.
Current Link Speed :
Provides the current link speed of the port.
Configured Link Speed :
Selects any available link speed for the given switch port. Only speeds supported
by the specific port is shown. Possible speeds are:
Disabled - Disables the switch port operation.
Auto - Port auto negotiating speed with the link partner and selects the highest
speed that is compatible with the link partner.
10Mbps HDX - Forces the cu port in 10Mbps half duplex mode.
10Mbps FDX - Forces the cu port in 10Mbps full duplex mode.
L2+ Managed 20-port 100Base-FX/1000Base-X SFP + 4-port 10/100/1000Base-T or
100Mbps HDX - Forces the cu port in 100Mbps half duplex mode.
100Mbps FDX - Forces the cu port in 100Mbps full duplex mode.
1Gbps FDX - Forces the port in 1Gbps full duplex
2.5Gbps FDX - Forces the Serdes port in 2.5Gbps full duplex mode.
SFP_Auto_AMS - Automatically determines the speed of the SFP. Note: There is
no standardized way to do SFP auto detect, so here it is done by reading the SFP
rom. Due to the missing standardized way of doing SFP auto detect some SFPs
might not be detectable. The port is set in AMS mode. Cu port is set in Auto mode.
100-FX - SFP port in 100-FX speed. Cu port disabled.
100-FX_AMS - Port in AMS mode. SFP port in 100-FX speed. Cu port in Auto
mode.
1000-X - SFP port in 1000-X speed. Cu port disabled.
1000-X_AMS - Port in AMS mode. SFP port in 1000-X speed. Cu port in Auto mode.
Ports in AMS mode with 1000-X speed has Cu port preferred. Ports in AMS mode
with 100-FX speed has fiber port preferred.
Flow Control :
When Auto Speed is selected on a port, this section indicates the flow control
capability that is advertised to the link partner. When a fixed-speed setting is
selected, that is what is used. The Current Rx column indicates whether pause
frames on the port are obeyed, and the Current Tx column indicates whether
pause frames on the port are transmitted. The Rx and Tx settings are determined
by the result of the last Auto-Negotiation.
Check the configured column to use flow control. This setting is related to the
setting for Configured Link Speed.
Maximum Frame Size :
Enter the maximum frame size allowed for the switch port, including FCS.
Excessive Collision Mode :
Configure port transmit collision behavior.
Discard: Discard frame after 16 collisions (default).
Restart: Restart backoff algorithm after 16 collisions.
