Operation of Web-based Management

Initial
Configuration

This chapter instructs you how to configure and manage the
through the web user interface. With this facility, you can easily access and monitor
through any one port of the switch all the status of the switch, including MIBs status,
each port activity, Spanning tree status, port aggregation status, multicast traffic,
VLAN and priority status, even illegal access record and so on.

T

he default values of ET24222MPp-S are listed in the table below:

IP Address 192.168.2.1

Subnet Mask 255.255.255.0

Default Gateway 192.168.1.254

Username admin

Password system

After ET24222MPp-S has been finished configuration the it interface, you can browse
it. For instance, type http://192.168.2.1 in the address row in a browser, it will show
the following screen and ask you inputting username and password in order to login
and access authentication.

ET24222MPp-S

The default username is “admin” and password is system. For the first time to use,
please enter the default username and password, and then click the <Login> button.
The login process now is completed. In this login menu, you have to input the
complete username and password respectively, the ET24222MPp-S will not give you a

shortcut to username automatically. This looks inconvenient,

In ET24222MPp-S, allowed two or more users using administrator’s identity to
manage this switch, which administrator to do the last setting, it will be an available
configuration to effect the system.

OTE

:

When you login the Switch WEB/CLI to manager. You must first type the
Username of the admin. Password was blank, so when you type after the
end Username, please press enter. Management page to enter WEB/CLI.

When you login ET24222MPp-S switch Web UI management, you can use
both ipv4 ipv6 login to manage

To optimize the display effect, we recommend you use Microsoft IE 6.0
above, Netscape V7.1 above or FireFox V1.00 above and have the resolution
1024x768. The switch supported neutral web browser interface

but safer.

Figure 2-1.1: System Information

Parameter description:

 System Contact:

The textual identification of the contact person for this managed node, together with
information on how to contact this person. The allowed string length is 0 to 128, and the
allowed content is the ASCII characters from 32 to 126.

 System name:

ET24222MPp-S

configure the IPv4 address and mask of the interface using the DHCP protocol. The DHCP
client will announce the configured System Name as hostname to provide DNS lookup.

 IPv4 DHCP Fallback Timeout

If the IPv6 gateway address is not link-local, system ignores the next hop VLAN for the
gateway.

2-1.3 NTP

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.

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:

Enabled: Enable server mode operation.

Disabled: Disable server mode operation.

 Server Address :

2-2 Green Ethernet

EEE is a power saving option that reduces the power usage when there is low or no traffic
utilization.

ET24222MPp-S

10/100/1000Base-TX or 100/1000Base-FX SFP Combo Ethernet Switch

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.

 EEE Urgent Queues :

Queues set will activate transmission of frames as soon as data is available. Otherwise the
queue will postpone transmission until a burst of frames can be transmitted.

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.
