Understanding the User Interfaces
The managed switch software includes a set of comprehensive management functions for
configuring and monitoring the system by using one of the following methods:
• Web user interface
• Simple Network Management Protocol (SNMP)
• Command-line interface (CLI)
Each of the standards-based management methods allows you to configure and monitor the
components of the managed switch software. The method you use to manage the system
depends on your network size and requirements, and on your preference.
The M4100 Series Managed Switch User Manual (this book) describes how to use the
web-based interface to manage and monitor the system.

Web Management Interface Overview
Your managed switch contains an embedded web server and management software for
managing and monitoring switch functions. The managed switch functions as a simple
switches without the management software. However, you can use the management
software to configure more advanced features that can improve switch efficiency and overall
network performance.
Web-based management lets you monitor, configure, and control your switch remotely using
a standard web browser instead of using expensive and complicated SNMP software
products. From your web browser, you can monitor the performance of your switch and
optimize its configuration for your network. You can configure all switch features, such as
VLANs, QoS, and ACLs, by using the web-based management interface.

Configure an IPv4 Management VLAN
For you to manage the device by using the web-based configuration utility, the device
management IP address must be defined and known. A management VLAN interface is
created by default and it is assigned an IP address if a DHCP server is present. If it fails to
get an IP address, a fallback address 169.254.100.100/255.255.0.0 is assigned to it.
Management VLAN is used as the default source interface for the syslog, message log, and

View or Set the System Time
The managed switch software supports the Simple Network Time Protocol (SNTP). You can
also set the system time manually.
SNTP assures accurate network device clock time synchronization up to the millisecond.
Time synchronization is performed by a network SNTP server. The managed switch software
operates only as an SNTP client and cannot provide time services to other systems.
Time sources are established by stratums. Stratums define the accuracy of the reference
clock. The higher the stratum (where zero is the highest), the more accurate the clock. The
device receives time from stratum 1 and above since it is itself a stratum 2 device.
The following is an example of stratums:
• Stratum 0. A real-time clock is used as the time source, for example, a GPS system.
• Stratum 1. A server that is directly linked to a stratum 0 time source is used. Stratum 1
time servers provide primary network time standards.
Configure System Information
37
Page 38
M4100 Series Managed Switch
• Stratum 2. The time source is distanced from the stratum 1 server over a network path.
For example, a stratum 2 server receives the time over a network link, through NTP, from
a stratum 1 server.
Information received from SNTP servers is evaluated based on the time level and server
type.
SNTP time definitions are assessed and determined by the following time levels:
• T1. Time that the original request was sent by the client.
• T2. Time that the original request was received by the server.
• T3. Time that the server sent a reply.
• T4. Time that the client received the server's reply.
The device can poll unicast server types for the server time.
Polling for unicast information is used for polling a server for which the IP address is known.
SNTP servers that were configured on the device are the only ones that are polled for
synchronization information. T1 through T4 are used to determine server time. This is the
preferred method for synchronizing device time because it is the most secure method. If this
method is selected, SNTP information is accepted only from SNTP servers defined on the
device using the SNTP Server Configuration screen.
The device retrieves synchronization information, either by actively requesting information or
at every poll interval.
Configure SNTP Global Settings
You can view and adjust date and time settings. SNTP stands for Simple Network Time
Protocol. As its name suggests, it is a less complicated version of Network Time Protocol,
that is a system for synchronizing the clocks of networked computer systems, primarily when
data transfer is handled through the Internet.
To configure SNTP global settings:
1. Prepare your computer with a static IP address in the 169.254.100.0 subnet, for
example, 169.254.100.201.
2. Connect an Ethernet cable from an Ethernet port on your computer to an Ethernet port on

8. Select System
Management > Time Time Configuration, and select SNTP as the

9. Use Client Mode to specify the mode of operation of SNTP Client.
An SNTP client can operate in one of the following modes:
• Disable. SNTP is not operational. No SNTP requests are sent from the client nor are
any received SNTP messages processed.
• Unicast. SNTP operates in a point-to-point fashion.
A unicast client sends a request
to a designated server at its unicast address and expects a reply from which it can
determine the time and, optionally, the round-trip delay and local clock offset relative
to the server.
• Broadcast. SNTP operates in the same manner as multicast mode but uses a local
broadcast address instead of a multicast address.
The broadcast address was a
single subnet scope while a multicast address has Internet wide scope.
The default value is Disable.
10. Use Port to specify the local UDP port to listen for responses or broadcasts.
The allowed range is 1 to 65535. The default value is 123.
11. Specify the Source Interface to be used for SNTP Client.
Possible values are as follows:
• Routing interface
• Routing VLAN

• Routing loopback interface
By default, VLAN 1 is used as the source interface.
12. Use Unicast Poll Interval to specify the number of seconds between unicast poll requests
expressed as a power of two when configured in unicast mode.
The allowed range is 6 to 10. The default value is 6.
13. Use Broadcast Poll Interval to specify the number of seconds between broadcast poll
requests expressed as a power of two when configured in broadcast mode.
Broadcasts received prior to the expiry of this interval are discarded. The allowed range is
6 to 10. The default value is 6.
14. Use Unicast Poll Timeout to specify the number of seconds to wait for an SNTP response
when configured in unicast mode.
The allowed range is 1 to 30. The default value is 5.
15. Use Unicast Poll Retry to specify the number of times to retry a request to an SNTP server
after the first time-out before attempting to use the next configured server when configured in
unicast mode.
The allowed range is 0 to 10. The default value is 1.
When using SNTP/NTP time servers to update the switch's clock, the time data received
from the server is based on Coordinated Universal Time (UTC), that is the same as
Greenwich Mean Time (GMT). This cannot be the time zone in which the switch is
located.
16. Use Time Zone Name to specify the time zone name.
The time zone can affect the display of the current system time. The default value is UTC.
17. Use Offset Hours to specify the number of hours difference from UTC. You can configure a
time zone specifying the number of offset hours and optionally the number of offset minutes
that the switch’s time zone is different from UTC.
The allowed range is -24 to 24. The default value is 0.
18. Use Offset Minutes to specify the number of minutes that the switch’s time zone is different
from UTC.
The allowed range is 0 to 59. The default value is 0.

LLDP Overview
The IEEE 802.1AB-defined standard, Link Layer Discovery Protocol (LLDP), allows stations
on an 802 LAN to advertise major capabilities and physical descriptions. This information is
viewed by a network manager to identify system topology and detect bad configurations on
the LAN.
LLDP is a one-way protocol; there are no request/response sequences. Information is
advertised by stations implementing the transmit function, and is received and processed by
stations implementing the receive function. The transmit and receive functions can be
enabled or disabled separately per port. By default, both transmit and receive are disabled on
all ports. The application is responsible for starting each transmit and receive state machine
appropriately, based on the configured status and operational state of the port.
The Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED) is an
enhancement to LLDP with the following features:
• Auto-discovery of LAN policies such as VLAN, Layer 2 Priority, and DiffServ settings,
enabling plug and play networking.
• Device location discovery for creation of location databases.
• Extended and automated power management of Power over Ethernet endpoints.
• Inventory management, enabling network administrators to track their network devices
and determine their characteristics (manufacturer, software and hardware versions, serial
or asset number).
