1.5 Function Descriptions
1.5.1 LACP Trunking Function
The switch provides a trunking function, which is compliant with 802.3ad standard. 802.3ad is a
specification from IEEE that allows us to bundle several physical port links together to form one logical
port , called a trunk between two devices. It supports Link Aggregation Control Protocol (LACP).
IEEE 802.3ad trunking also allows redundant connections between devices to be combined for more
aggregate bandwidth between devices supporting LACP.
The LACP provides a standardized means for exchanging information between two link partners on a link
to allow their Link Aggregation Control instances to reach agreement on the identity of the Link
Aggregation Group to which the link belongs, move the link to that Link Aggregation Group, and enable its
transmission and reception functions in an orderly manner.
The switch can support up to seven trunk groups , or called trunk ports or trunks. Each group is a logic
port and can have up to 4 physical port members. A physical port can only belong to one trunk group. Each
trunk group can be set LACP disabled or enabled. The operations are:
LACP disabled
If one trunk group is LACP disabled, it becomes a local static trunk and all member ports are forced to be
work ports. The link aggregation is formed and there is no LACP negotiation taking place. Maximal four
member ports are allowed.
LACP enabled
If one trunk group is LACP enabled, it is called LACP static trunk. Link aggregation is formed through
LACP negotiation between link partners.
Up to four ports can be selected as member ports for each trunk group. However, the max. two ports, called
work ports can be aggregated at the same time. Those member ports which are not work ports are standby
to become work port if any current work port fails to operate. This transition takes about 30 seconds. Each
member port can be set LACP Passive or LACP active as described below:
LACP Passive : The port does not initiate the LACP negotiation, but it does understand the LACP packet.
It will reply to the received LACP packet to eventually form the link aggregation if its link partner is
requesting to do so (in active state).
LACP Active : The port is willing to form an aggregate link, and initiate the negotiation. The link
aggregate will be formed if its link partner is running in LACP active or passive mode.
There are only three valid combinations to run the LACP link aggregate as follows:
_ disabled to disabled state (forced link aggregate without LACP)
_ active to active state
_ active to passive state
Rules of trunking
1. Up to seven trunk groups (trunk ports) can be created.
2. Each trunk group can be composed of up to 4 member ports.
3. The member port can be one of Port 1 ~ Port 24 and G1 - G2 port.
4. One switched port only can belong to one trunk group.
5. If VLAN group exist, all members of one static trunk group must be in same VLAN group.
6. LACP operation requires member ports in full-duplex mode.
7. In a static trunk group (LACP disabled), four work ports are aggregated at the same time.
8. In an LACP trunk group, maximal two work ports can be aggregated at the same time.
1.5.2 IP Multicast Function
Internet Protocol (IP) multicast is a bandwidth-conserving technology that reduces traffic by
simultaneously delivering a single stream of information to thousands of corporate recipients and homes.
Applications that take advantage of multicast include video conference, corporate communications,
distance learning, and distribution of software, stock quotes, and news.
IP Multicast delivers source traffic to multiple receivers without adding any additional burden on the source
or the receivers while using the least network bandwidth of any competing technology. Multicast packets
are replicated in the network by the devices supporting multicast protocols resulting in the most efficient
delivery of data to multiple receivers possible.
Multicast is based on the concept of a group. An arbitrary group of receivers expresses an interest in
receiving a particular data stream. This group does not have any physical or geographical boundaries - the
hosts can be located anywhere on the Internet. Hosts that are interested in receiving data flowing to a
particular group must join the group using IGMP. Hosts must be a member of the group to receive the data
stream.
IP Multicast address
IP Multicast addresses specify an arbitrary group of IP hosts that have joined the group and want to receive
traffic sent to this group. IP multicast addresses range from 224.0.0.0 through 239.255.255.255. This
address range is only for the group address or destination address of IP multicast traffic. The source address
for multicast datagrams is always the unicast source address.
IGMP
Internet Group Management Protocol (IGMP) is used to dynamically register individual hosts in a multicast
group on a particular LAN. Hosts identify group memberships by sending IGMP messages to their local
multicast router. Under IGMP, routers listen to IGMP messages and periodically send out queries to
discover which groups are active or inactive on a particular subnet.
RFC 2236 defines the specification for IGMP Version 2. There are four types of IGMP messages:
_ Membership query
_ IGMP Version 1 membership report
_ IGMP Version 2 membership report
_ Leave group
Hosts send out IGMP membership reports corresponding to a particular multicast group to indicate that
they are interested in joining that group. The router periodically sends out an IGMP membership query to
verify that at least one host on the subnet is still interested in receiving traffic directed to that group. When
there is no reply to three consecutive IGMP membership queries, the router times out the group and stops
forwarding traffic directed toward that group.
With leave group message, the hosts can actively communicate to the local multicast router their intention
to leave the group. The router then sends out a group-specific query and determines whether there are any
remaining hosts interested in receiving the traffic. If there are no replies, the router times out the group and
stops forwarding the traffic.
IGMP Snooping
IGMP snooping requires the LAN switch to examine, or snoop, some Layer 3 information in the IGMP
packets sent between the hosts and the router. When the switch hears the IGMP host report from a host for
a particular multicast group, the switch adds the host's port number to the associated multic ast table entry.
When the switch hears the IGMP leave group message from a host, it removes the host's port from the table
entry.
Multicast Forwarding
In multicast routing, the source is sending traffic to an arbitrary group of hosts represented by a multicast
group address. The multicast router must determine which direction is upstream (toward the source) and
which direction (or directions) is downstream. If there are multiple downstream paths, the router replicates
the packet and forwards the traffic down the appropriate downstream paths - which is not necessarily all
paths.
The switch can support IP multicast if IGMP protocol is enabled. IGMP snooping function and status is
also provided. Each IP multicast address is associated one Vlan ID and its member ports. The information
is available from management interfaces.
1.5.3 MAC Address Filtering Function
MAC address filtering allows the switch to drop unwanted traffic. Incoming traffic is filtered based on the
destination MAC addresses (DAs). The unwanted destination addresses are cal led filter MAC addresses.
The switch provides management function that allows LAN administrator to maintain the filter MAC
address table.
1.5.4 Static MAC Address
The switch provides Static MAC Address setup function. The static MAC addresses are the MAC
addresses which are setup by LAN administrators and are not learned by the switch automatically.
The static addresses are stored and referred in switch MAC address table permanently regardless of
whether the MAC addresses are physically disconnected to the switch.
Applying this function with port security function allows LAN administrator to build a protection
mechanism that let switch only serves granted devices.
Static MAC address related settings:
Mac Address : Static Ethernet MAC address (12 digits)
Port num : The port number where the MAC address is located
Vlan ID : The associated Vlan ID to the address, if 802.1Q VLAN is enabled.
1.5.5 Port Security
A port in security mode does not learn any source MAC address (SA). Only the incoming packets with SA
existing in the switch static MAC address table can be forwarded normally. Otherwise, the packets are
dropped. This features provides a protection mechanism to restrict the devices link to the switch port.
Only devices with valid MAC addresses can be served by the switch.
1.5.6 VLAN Function
Virtual LANs (VLANs) can be viewed as a group of devices on different physical LAN segments which
can communicate with each other as if they were all on the same physical LAN segment. It can create a
network that is independent of physical location and group users into logical workgroups. The benefits are:
_ Confine broadcast traffic and Increased performance
_ Improved manageability
_ Network tuning and simplification of software configurations
_ Physical topology independence
Increased security options
_
The switch supports port-based, 802.1Q (Tag-based) and protocol-based VLAN. In the default
configuration, VLAN function is disabled.
1.5.6.1 Port-based VLAN
Up to 26 VLAN groups can be created. Each group has its own port members. The member ports are
selected among the physical ports on the switch. Packets can go among only members in the same VLAN
group.
Required configurations:
_ Maintain (Create/delete/modify) VLAN groups
_ Manage the port members of each VLAN group
Note:
1. The ports which are not belonging to any group are treated as belonging to another single VLAN.
2. A trunk group is treated as a physical port.
3. VLAN -tagging is ignored in port-based VLAN mode.
1.5.6.2 IEEE 802.1Q VLAN (Tag-based VLAN)
Tag-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to create a VLAN
across devices from different venders. IEEE 802.1Q VLAN uses a technique to insert a tag into the
Ethernet frames. Tag contains a VLAN Identifier (VID) that indicates the VLAN numbers.
The switch can classify each received packet as belonging to one and only one VLAN. If the received
packet is VLAN-tagged, the packet is classified as belonging to the VLAN specified in the VLAN tag
header. If the received packet is untagged, it is classified as belonging to the default VLAN configured for
the ingress port.
Required configurations:
_ Enable or disable GVRP support
_ VLAN information including VID (2- 4094) and name
_ Tagged member ports of each VLAN
_ Outgoing tag mode for each member port
Tag - outgoing frames with VLAN-tagged
Untag - outgoing frames without VLAN-tagged
_ PVID (Port VID, 1- 255 for untagged incoming frames) for each port
_ Ingress Rule 1 setting for each port : forward only packets with VID
matching configured PVID
Ingress Rule 2 setting for each port : drop untagged frames
_
PVID : this feature is useful to accommodate the devices which do not support tagging to participate in the
VLAN.
GVRP - GARP [Generic Attribute Registration Protocol] VLAN Registration Protocol : GVRP
allows automatic VLAN configuration between the switch and nodes. If the switch is connected to a device
with GVRP enabled, you can send a GVRP request using the VID of a VLAN defined on the switch, the
switch will automatically add that device to the existing VLAN. (GVRP - 802.1Q compliant, GARP -
802.1P compliant)
1.5.6.3 Protocol-based VLAN
In order for an end station to send packets to different VLANs, it itself has to be either capable of tagging
packets it sends with VLAN tags or attached to a VLAN -aware bridge that is capable of classifying and
tagging the packet with different VLAN ID based on not only default PVID but also other information
about the packet, such as the protocol. The switch can support 802.1v compliant protocol-based VLAN
classification by means of both built - in knowledge of layer 2 packet formats used by selected popular
protocols, such as Novell IPX and AppleTalk`s EtherTalk, and others. Required configuration:
_ Protocol setting for each VLAN group defined in 802.1Q VLAN mode
_ If more than two V LAN groups are configured with same protocol
value, make sure the member ports of those groups are not overlaping.
Any incoming untagged packet is checked and classified according the Protocol vs. VLAN mapping
settings. If an associated VLAN group is found, the packet is calssified and is inserted with VID tag of the
group VLAN ID instead of input port PVID.
1.5.7 Spanning Tree Protocol
Spanning-Tree Protocol (STP) is a link management protocol that provides path redundancy while
preventing undesirable loops in the network. For an Ethernet network to function properly, only one active
path must exist between two stations. Multiple active paths between stations cause loops in the network. If
a loop exists in the network, you might receive duplicate messages. When loops occur, some switches see
stations on both sides of the switch. This condition confuses the forwarding algorithm and allows duplicate
frames to be forwarded.
To provide path redundancy, Spanning -Tree Protocol defines a tree that
spans all switches in an extended network. Spanning-Tree Protocol forces
certain redundant data paths into a standby (blocked) state. If one network segment in the Spanning-Tree
Protocol becomes unreachable, or if
Spanning-Tree Protocol costs change, the spanning-tree algorithm
re-configures the spanning- tree topology and reestablishes the link by
activating the standby path.
Spanning-Tree Protocol operation is transparent to end stations, which
are unaware whether they are connected to a single LAN segment or a
switched LAN of multiple segments.
STP related parameters
Priority : A value to identify the root bridge. The bridge with the lowest value has the highest priority and
is selected as the root.
MAC Address : The MAC address of the switch as a unique identifier
to the network.
Max Age : The number of seconds a bridge waits without receiving Spanning Tree protocol configuration
messages before attempting a reconfiguration. Maximum Age Timer measures the age of the received
protocol information recorded for a port and ensures that this information is discarded when its age limit
exceeds the value of the maximum age parameter recorded by the switch. The time-out value for this timer
is the maximum age parameter of the switches.
Hello Time : The number of seconds between the transmission of Spanning Tree protocol configuration
messages. It determines how often the switch broadcasts its hello message to other switches.
Forward Delay Time : The number of seconds a port waits before changing from its Spanning Tree
Protocol learning and listening states to the forwarding state. Forward Delay Timer Monitors the time spent
by a port in the learning and listening states. The time-out value is the forward delay parameter of
Spanning tree port states
Listening : Switches send messages to one another to establish the network topology and the optimal paths
to the different segments of the network. Other data is not transmitted.
Blocking : The switch enters the Blocking State if a path with higher priority is found to exist during the
Listening State. Normal data is not transmitted.
Learning : The switch enters the Learning State if no path with a higher priority is found during the
Listening State. Learned entries are entered in the Unicast Destination Forwarding Table. Normal data
is not transmitted.
Forwarding : The switch enters the Forwarding State after having been in the Learning State for a
predefined time period. Normal data is transmitted.
Per port control settings
PathCost : Specifies the path cost for each port. The Spanning-Tree Protocol uses port path costs to
determine which port to select as a forwarding port. You should assign lower numbers to ports attached to
faster media (such as full duplex), and higher numbers to ports attached to slower media. The possible
range is 1 to 65535. The recommended path cost is 1000 divided by LAN speed in megabits per second.
Priority : Specify STP port priority for each port. The port (physical or logical) with the lowest priority
value has the highest priority and forwards the spanning-tree frames. The possible priority range is 0
through 255 (decimal). The default is 128. If all ports have the same priority value, the lowest port number
forwards the spanning-tree frames.
1.5.8 Port Sniffer Function
Port sniffer function is a method to duplicate all traffic occurred on the specified monitored ports to the
designated sniffer port. The traffic can be configured for incoming packets only or outgoing packets only or
both. The control settings are:
Sniffer Mode : Specify the traffic type for monitoring
Options - Disable, Rx=incoming, Tx=outgoing, Both=Rx&Tx
Sniffer Port : Specify the port where performs monitoring
Monitored Port : Select the ports whose traffic will be duplicated to the monitoring port. Press Space key
for selection from the port member list.
1.5.9 QoS Priority Function
This switch supports two priority levels, high and low, and provides two priority functions:
1. Port-based Priority (Static priority)
2. 802.1p Priority (VLAN tagged priority)
Priority Classification Methods
Static priority is called port -based priority. The priority level of a receiving packet is determined by the
configured priority of the input port where the packet is received and the content of the packet is ignored.
Each port must be pre-configured with a priority level for incoming frames or disabled setting.
802.1p Priority is a content -based priority method. If the receiving packet is an 802.1Q VLAN tagged
packet, the switch will check the 3-bit User Priority value in TCI (Tag Control Information) field of packet
tag data. By this value, the packet is classified as high priority or low priority according to 802.1p priority
configuration. The map of priority values vs. priority levels must be pre-configured.
The switch uses the following rules:
1. Applies Static Priority method first for tagged or untagged packets.
2. If port static priority is disabled, applies 802.1p Priority method.
3. Untagged packets are treated as low priority.
Outgoing Service Policy
The switch provides two options for outgoing service policy for high priority packets and low priority
packets.
1. High priority always first
2. Round robin method with specified [High : Low] ratio setting
This policy configuration can be set via the management interface.
1.5.10 802.1X Port- Based Network Access Control
For some IEEE 802 LAN environments, it is desirable to restrict access to the services offered by the LAN
to those users and devices that are permitted to make use of those services. IEEE 802.1X Port-based
network access control function provide a means of authenticating and authorizing devices attached to a
LAN port that has point-to- point connection characteristics, and of preventing access to that port in cases in
which the authentication and authorization process fails. The 802.1X standard relies on the client to provide
credentials in order to gain acces s to the network. The credentials are not based on a hardware address.
Instead, they can be either a username/password combination or a certificate. The credentials are not
verified by the switch but are sent to a Remote Authentication Dial-In User Service (RADIUS) server,
which maintains a database of authentication information. 802.1X consists of three components for
authentication exchange, which are as follows:
_ An 802.1X authenticator: This is the port on the switch that has services to offer to an end device,
provided the device supplies the proper credentials.
_ An 802.1X supplicant: This is the end device; for example, a PC that connects to a switch that is
requesting to use the services (port) of the device. The 802.1X supplicant must be able to respond to
communicate.
_ An 802.1X authentication server: This is a RADIUS server that examines the credentials provided to the authenticator from the supplicant and provides
the authentication service. The authentication server is responsible for letting the authenticator know if services should be granted.
The 802.1X authenticator operates as a go -between with the supplicant and the authentication server to
provide services to the network. When a switch is configured as an authenticator, the ports of the switch
must then be configured for authorization. In an authenticator-initiated port authorization, a client is
powered up or plugs into the port, and the authenticator port sends an Extensible Authentication Protocol
(EAP) PDU to the supplicant requesting the identification of the supplicant. At this point in the process, the
port on the switch is connected from a physical standpoint; however, the 802.1X process has not authorized
the port and no frames are passed from the port on the supplicant into the switching engine. If the PC
attached to the switch did not understand the EAP PDU that it was receiving from the switch, it would not
be able to send an ID and the port would remain unauthorized. In this state, the port would never pass any
user traffic and would be as good as disabled. If the client PC is running the 802.1X EAP, it would respond
to the request with its configured ID. (This could be a username/password combination or a certificate.)
After the switch, the authenticator receives the ID from the PC (the supplicant). The switch then passes the
ID information to an authentication server (RADIUS server) that can verify the identification information.
The RADIUS server responds to the switch with either a success or failure message. If the response is a
success, the port will be authorized and user traffic will be allowed to pass through the port like any switch
port connected to an access device. If the response is a failure, the port will remain unauthorized and,
therefore, unused. If there is no response from the server, the port will also remain unauthorized and will
not pass any traffic.
The following configuration settings are required in the switch to make 802.1X function work:
Enable 802. 1X protocol
Radius client configuration -
Radius server IP : IP address of the Radius server
Shared key : en encryption key for use during authentication sessions with the specified Radius server. It
must match the key used on the Radius server.
NAS identifier : identifier for this Radius client
Server port : the UDP destination port for authentication requests to the specified Radius server
Accounting port : the UDP destination port for accounting requests to the specified Radius server
Per-port 802.1X mode setting:
Auto (Au) - The port is set to the Authorized or Unauthorized state in accordance with the outcome of an
authentication exchange between the Supplicant and the Authentication Server.
Forced Authorized (Fa) - The port is forced to be in authorized state.
Forced Unauthorized (Fu) - The port is forced to be in unauthorized state.
None (No) - The port is not necessary authorized.
Misc. configuration:
quietPeriod - the period during which the port does not try to acquire a supplicant
txPeriod - the period the port waits to retransmit the NEXT EAPOL PDU during an authentication session
suppTimeout - the period of time the switch waits for a supplicant response toan EAP request
serverTimeout - the period of time the switch waits for a server response to an authentication request
reAuthMax - the number of authentication attempts that must time- out before authentication fails and the
authentication session ends.
reAuthPeriod - the period of time after which the connected radius clients must be re-authenticated

2.6 Cooling Fans
The switch is equipped with two cooling fans. Both fans are featured with failure detection function. When
the fan operation speed is below the specification, it is detected as a failure. The fan status can be
monitored via management functions. One fan failure trap is also issued when fan failure event occurs.
Important :
Do not operate the switch unit when a fan failure is detected. Without normal operation of the cooling fans,
the switch unit might not operate properly or even might be damaged due to not enough ventilation. Return
the defective unit to the dealer where it was purchased.
2.7 Management Setup
The managed switch is featured with management functions and can be managed by using the following
methods:
_ Direct console connection over an RS-232 cable
_ Telnet software over TCP/IP network
_ SNMP manager software over TCP/IP network
_ Web browser software from Internet or Intranet over TCP/IP network
_ SNMP trap hosts from Internet or Intranet over TCP/IP network
The following figure illustrates a management model diagram:
2.7.1 Setup for Out -of-band (Console) Management
Before doing any in-band management, it is necessary to perform console operation for configuring IP and
SNMP related settings for the first time the switch is received for installation. Any PC running Windows
95/98/ or NT can be used as a console via COM port. Windows Hyper Terminal program is an ideal and the
most popular software for such console terminal operations.
To setup console operation, the steps are:
1. Find a proper RS-232 cable for the connection to a console terminal. If your are using PC as a terminal,
make sure the cable pin assignments comply to the following requirement.
Console port 9-pin PC COM port
Pin 2 RXD -------------------------------- 3
3 TXD -------------------------------- 2
4 DTR -------------------------------- 6
5 GND -------------------------------- 5
6 DSR -------------------------------- 4
2. Connect one end to the console port and connect the other end to the PC COM port.
3. Configure your PC COM port setting to match the RS-232 settings of the console port and start your
terminal software.
Factory default settings of the Console port
Baud rate : 9600, N, 8, 1, 0
Flow control : disabled
4. Turn the switch unit power on.
5. Press <Enter> key several times in your terminal software until a login prompt comes up. It means the
connection is proper.
The console port does not support modem connection. Refer to Chapter 3 for more information about
Console management.
2.7.2 Setup for In-band Management
To perform an in -band management, it is necessary to connect the system to your TCP/IP network. The
steps are:
1. Configure IP and SNMP related settings to the device using direct console management when you
receive it first time for the installation.
2. Find a proper straight-through Category 5 UTP cable (maximal length 100 meters) for the connection.
3. Connect one end of the UTP cable to the UTP port of the media converter and connect the other end to a
network device, such as a switching hub, in your TCP/IP network.
4. Start your in- band management operations. For different management methods, refer to:
_ Chapter 3 for Console and Telnet management
_ Chapter 4 for SNMP management
_ Chapter 5 for Web management
2.7.3 Quick Guide to Configure Switch IP Address
This section provides a quick instruction to configure a new IP address via Console port for the switch
received for the first time. The steps are:
1. Set up console connection as desc ribed in section 2.7.1.
2. Login with default username= admin and password=123.
3. Menu selections to enter IP configuration as follows:

4. SNMP Manageme nt
SNMP management are performed at a network management station running SNMP network management
application manager software. The following figure illustrates an example model:
The switch unit serves as an SNMP agent and provides the capabilities that allows network administrators
via SNMP protocol to set parameters and view switch status defined in the standard MIB-II and private
MIB. A trap manager is a management station that allows to receive SNMP traps. An SNMP trap is issued
by the switch when the associated trap event occurs in the switch.
4.1 Configuring SNMP Settings via Console Operation
Before performing SNMP operation, proper SNMP settings must be configured. The SNMP related settings
are:
Name : Logic name to identify the switch unit
Location : Location where the switch unit is installed
Contact : Contact person regarding the switch unit
Community string : SNMP communities to which the SNMP manager belongs and access right to the
switch unit ( read only or read/write)
Trap Managers : IP addresses of trap managers to which a trap is
issued and the community to which the trap manager belongs.
Up to four SNMP communities and up to three trap managers are supported by the system SNMP agent.
4.2 SNMP MIB-2 and Private MIB
Use the SNMP management application software to compile the MIB file first before performing any management operation. The
following MIB standards are supported:
RFC1213 MIB -2
RFC1493 Bridge MIB
RFC1643 Ethernet - like MIB
RFC1271 RMON MIB statistics, history, alarm, event group
Private MIB (Device Specific)
