2 Operation of Web-based Management
Initial Configuration
This chapter instructs you how to configure and manage the GS-2300 series 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, illegal
access record, etc.
The default values of the GS-2300 series are listed in the table below:
172.23.56.250IP Address
255.255.255.0Subnet Mask
172.23.56.254Default Gateway
adminUsername
adminPassword
After the switch has finished the configuration of the interface, you can browse it. For instance, type http://172.23.56.250
in the address bar of a web browser, it will show the following screen and ask you to input your username and password
in order to login and access authentication.
The default username is "admin" and the password is "admin". When logging in for the first time, please use the default
username and password, and then click the "Login" button. The login process now is completed. In the login menu, you
have to use the complete username and password respectively, the GS-2300 series will not give you a shortcut to a
username automatically. This looks inconvenient, but is more secure.
In the GS-2300 series, the user management allows only one administrator to configure the system at the same time. If
there are two or more users using administrator access, it will allow the one who logins first to configure the system.
The rest of the users, even with administrator access, can only monitor the system. Those who have no administrator
access can only monitor the system regardless. Only a maximum of three users are able to login simultaneously in the
GS-2300 series.
5
When you first login on the switch using the web you must use the default username and password.
Both IPv4 and IPv6 are supported for management functions.
The switch supports a neutral web browser interface.

The GS-2300 series is set to DHCP by default. If you do not have a DHCP server to provide an IP address to the
switch, the default IP is 172.23.56.250

2.1 Connecting network devices
The switch is designed to be connected to 10, 100 or 1000Mbps network cards in PCs and servers, as well as to other
switches and hubs. It may also be connected to remote devices using optional SFP transceivers.
2.2 Twisted-pair devices
Each device requires an unshielded twisted-pair (UTP) cable with RJ45 connectors at both ends. Use Category 5, 5e or
6 cable for 1000BASE-T connections, Category 5 or better for 100BASE-TX connections.
2.3 Cabling guidelines
The RJ45 ports on the switch support automatic MDI/MDI-X pin-out configuration, so you can use standard straight-through
twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).
See Appendix B for further information on cabling.
5
CAUTION: Do not plug a phone jack connector into an RJ45 port. This will damage the switch. Use only twisted-pair
cables with RJ45 connectors that conform to FCC standards.
CONNECTING TO PCS, SERVERS, HUBS AND SWITCHES
Step 1: Attach one end of a twisted-pair cable segment to the device’s RJ45 connector.
Figure 16: Making Twisted-Pair Connections
10
LANCOM GS-2310P/GS-2326(P) User Manual
2 Operation of Web-based Management
Page 11
Step 2: If the device is a network card and the switch is in the wiring closet, attach the other end of the cable segment
to a modular wall outlet that is connected to the wiring closet. (See the section “Network Wiring Connections.”) Otherwise,
attach the other end to an available port on the switch.
Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length.
5
Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise
back pressure jamming signals may degrade overall performance for the segment attached to the hub.
Step 3: As each connection is made, the Link LED (on the switch) corresponding to each port will light green (1000 Mbps)
or amber (100 Mbps) to indicate that the connection is valid.
NETWORK WIRING CONNECTIONS
Today, the patch-down block is an integral part of many of the newer equipment racks. It is actually part of the patch
panel. Instructions for making connections in the wiring closet with this type of equipment follows.
Step 1: Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel.
Step 2: If not already in place, attach one end of a cable segment to the back of the patch panel where the punch-down
block is located, and the other end to a modular wall outlet.
Step 3: Label the cables to simplify future troubleshooting. See “Cable Labeling and Connection Records”.

3.1.6 EEE
EEE is a power saving option that reduces the power usage when there is very low traffic utilization (or no traffic).
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 information about the devices wakeup time using the LLDP protocol.
For maximizing the power saving, the circuit isn't started at once transmit data are ready for a port, but is instead queued
until 3000 bytes of data are ready to be transmitted. For not introducing a large delay in case that data less than 3000
bytes shall be transmitted, data are always transmitted after 48 us, giving a maximum latency of 48 us + the wakeup
time.
18
LANCOM GS-2310P/GS-2326(P) User Manual
3 Configuration
Page 19
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.

3.2 ACL
The GS-2300 series access control list (ACL) is probably the most commonly used object in the firmware. It is used for
packet filtering but also for selecting types of traffic to be analyzed, forwarded, or influenced in some way. The ACLs are
divided into EtherTypes. IPv4, ARP protocol, MAC and VLAN parameters etc. Here we will just go over the standard and
extended access lists for TCP/IP. As you create ACEs for ingress classification, you can assign a policy for each port, the
policy number is 1-8. However, each policy can be applied to any port. This makes it very easy to determine what type
of ACL policy you will be working with.
3.2.1 Ports
The section describes how to configure the ACL parameters (ACE) of the each switch port. These parameters will affect
frames received on a port unless the frame matches a specific ACE.
Web Interface

3.2.3 Access Control List
The section describes how to configure Access Control List rules. An Access Control List (ACL) is a sequential list of permit
or deny conditions that apply to IP addresses, MAC addresses, or other more specific criteria. This switch tests ingress
packets against the conditions in an ACL one by one. A packet will be accepted as soon as it matches a permit rule, or
dropped as soon as it matches a deny rule. If no rules match, the frame is accepted. Other actions can also be invoked
when a matching packet is found, including rate limiting, copying matching packets to another port or to the system
log, or shutting down a port.
This page shows the Access Control List (ACL), which is made up of the ACEs defined on this switch. Each row describes
the ACE that is defined. The maximum number of ACEs is 256 on each switch. Click on the lowest plus sign to add a
new ACE to the list. The reserved ACEs are used for internal protocol and cannot be edited or deleted, the order sequence
cannot be changed and the priority is highest

3.3 Aggregation
You can bundle more than one port with the same speed, full duplex and the same MAC to be a single logical port, thus
the logical port aggregates the bandwidth of these ports. This means you can apply your current Ethernet equipment’s
to build the bandwidth aggregation. For example, if there are three Fast Ethernet ports aggregated in a logical port,
then this logical port has bandwidth three times as high as a single Fast Ethernet port has.
3.3.1 Static Trunk
The Aggregation Configuration is used to configure the settings of Link Aggregation. You can bundle more than one
port with the same speed, full duplex and the same MAC to be a single logical port, thus the logical port aggregates the
bandwidth of these ports. This means you can apply your current Ethernet equipment’s to build the bandwidth aggregation.
3-3.1.1 Static Trunk
Ports using Static Trunk as their trunk method can choose their unique Static GroupID to form a logic “trunked port”.
The benefit of using Static Trunk method is that a port can immediately become a member of a trunk group without any
handshaking with its peer port. This is also a disadvantage because the peer ports of your static trunk group may not
know that they should be aggregate together to form a “logic trunked port”. Using Static Trunk on both end of a link is
strongly recommended. Please also note that low speed links will stay in “not ready” state when using static trunk to
aggregate with high speed links.

3.3.2 LACP
Ports using Link Aggregation Control Protocol (according to IEEE 802.3ad specification) as their trunking method can
choose their unique LACP GroupID to form a logic “trunked port”. The benefit of using LACP is that a port makes an
agreement with its peer port before it becomes a ready member of a “trunk group” (also called aggregator). LACP is
safer than the other trunking method - static trunk.

3.4 Spanning Tree
The Spanning Tree Protocol (STP) can be used to detect and disable network loops, and to provide backup links between
switches, bridges or routers. This allows the switch to interact with other bridging devices (that is, an STP-compliant
switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network,
and provide backup links which automatically take over when a primary link goes down.
STP - STP uses a distributed algorithm to select a bridging device (STP- compliant switch, bridge or router) that serves
as the root of the spanning tree network. It selects a root port on each bridging device (except for the root device) which
incurs the lowest path cost when forwarding a packet from that device to the root device. Then it selects a designated
bridging device from each LAN which incurs the lowest path cost when forwarding a packet from that LAN to the root
device. All ports connected to designated bridging devices are assigned as designated ports. After determining the lowest
cost spanning tree, it enables all root ports and designated ports, and disables all other ports. Network packets are
therefore only forwarded between root ports and designated ports, eliminating any possible network loops.

Page 34
Once a stable network topology has been established, all bridges listen for Hello BPDUs (Bridge Protocol Data Units)
transmitted from the Root Bridge. If a bridge does not get a Hello BPDU after a predefined interval (Maximum Age), the
bridge assumes that the link to the Root Bridge is down. This bridge will then initiate negotiations with other bridges
to reconfigure the network to reestablish a valid network topology.

Parameter description:
Port:
The switch port number of the logical STP port.
STP Enabled:
Controls whether STP is enabled on this switch port.
Path Cost:
Controls the path cost incurred by the port. The Auto setting will set the path cost as appropriate by the physical link
speed, using the 802.1D recommended values. Using the Specific setting, a user-defined value can be entered. The path
cost is used when establishing the active topology of the network. Lower path cost ports are chosen as forwarding ports
in favor of higher path cost ports. Valid values are in the range 1 to 200000000.
Priority:
Controls the port priority. This can be used to control priority of ports having identical port cost. (See above).
operEdge (state flag):
Operational flag describing whether the port is connecting directly to edge devices. (No Bridges attached). Transition to
the forwarding state is faster for edge ports (having operEdge true) than for other ports. The value of this flag is based
on AdminEdge and AutoEdge fields. This flag is displayed as Edge in Monitor->Spanning Tree -> STP Detailed Bridge
Status.
AdminEdge:
Controls whether the operEdge flag should start as set or cleared. (The initial operEdge state when a port is initialized).
AutoEdge:
Controls whether the bridge should enable automatic edge detection on the bridge port. This allows operEdge to be
derived from whether BPDU's are received on the port or not.
Restricted Role:
If enabled, causes the port not to be selected as Root Port for the CIST or any MSTI, even if it has the best spanning tree
priority vector. Such a port will be selected as an Alternate Port after the Root Port has been selected. If set, it can cause
lack of spanning tree connectivity. It can be set by a network administrator to prevent bridges external to a core region
of the network influence the spanning tree active topology, possibly because those bridges are not under the full control
of the administrator. This feature is also known as Root Guard.
Restricted TCN:

If enabled, causes the port not to propagate received topology change notifications and topology changes to other ports.
If set it can cause temporary loss of connectivity after changes in a spanning tree's active topology as a result of persistently
incorrect learned station location information. It is set by a network administrator to prevent bridges external to a core
region of the network, causing address flushing in that region, possibly because those bridges are not under the full
control of the administrator or the physical link state of the attached LANs transits frequently.
BPDU Guard:
If enabled, causes the port to disable itself upon receiving valid BPDU's. Contrary to the similar bridge setting, the port
Edge status does not affect this setting. A port entering error-disabled state due to this setting is subject to the bridge
Port Error Recovery setting as well.
Point to Point
Controls whether the port connects to a point-to-point LAN rather than to a shared medium. This can be automatically
determined, or forced either true or false. Transition to the forwarding state is faster for point-to-point LANs than for
shared media.

3.5 IGMP Snooping
IGMP Snooping is used to establish the multicast groups to forward the multicast packet to the member ports, and, in
nature, avoids wasting the bandwidth while IP multicast packets are running over the network. This is because a switch
that does not support IGMP or IGMP Snooping can not tell the multicast packet from the broadcast packet, so it can
only treat them all as the broadcast packet. Without IGMP Snooping, the multicast packet forwarding function is plain
and nothing is different from broadcast packet.
A switch which supports IGMP Snooping with the functions of query, report and leave, a type of packet exchanged
between IP Multicast Router/Switch and IP Multicast Host, can update the information of the Multicast table when a
member (port) joins or leaves an IP Multicast Destination Address. With this function, once a switch receives an IP
multicast packet, it will forward the packet to the members who joined in a specified IP multicast group before.
The packets will be discarded by the IGMP Snooping if the user transmits multicast packets to the multicast group that
had not been built up in advance. IGMP mode enables the switch to issue IGMP function that you enable IGMP proxy
or snooping on the switch, which connects to a router closer to the root of the tree. This interface is the upstream
interface. The router on the upstream interface should be running IGMP.

3.5.3 Port Group Filtering
The section describes how to set the IGMP Port Group Filtering. In some network Application environments, like
metropolitan or multiple-dwelling unit (MDU) installations, a user might want to control the multicast groups to which
a user on a switch port can belong. It allows the user to control the distribution of multicast services, such as IP-TV,
based on some type of subscription or service plan.
With this feature, you can filter multicast joins on a per-port basis by configuring IP multicast profiles and associating
them with individual switch ports. An IGMP profile can contain one or more multicast groups and specifies whether
access to the group is permitted or denied. If an IGMP profile denying access to a multicast group is applied to a switch
port, the IGMP join report requesting the stream of IP multicast traffic is dropped, and the port is not allowed to receive
IP multicast traffic from that group. If the filtering action permits access to the multicast group, the IGMP report from
the port is forwarded for normal processing.
IGMP filtering controls only IGMP membership join reports and has no relationship to the function that directs the
forwarding of IP multicast traffic.

3.5.6 IPv4 SSM information
Source Specific Multicast (SSM) is a datagram delivery model that best supports one-to-many applications, also known
as broadcast applications. SSM is a core network technology of IP multicast targeted for audio and video broadcast
application environments.
For the SSM delivery mode, an IP multicast receiver host must use IGMP Version 3 (IGMPv3) to subscribe to channel (S,
G). By subscribing to this channel, the receiver host is indicating that it wants to receive IP multicast traffic sent by source
host S to group G. The network will deliver IP multicast packets from source host S to group G to all hosts in the network
that have subscribed to the channel (S, G).

SSM does not require group address allocation within the network, only within each source host. Different applications
running on the same source host must use different SSM groups. Different applications running on different source hosts
can arbitrarily reuse SSM group addresses without causing any excess traffic on the network.
Addresses in the range 232.0.0.0/8 (232.0.0.0 to 232.255.255.255) are reserved for SSM by IANA. In the switch, you

3.6 MLD Snooping
Curiously enough, a network node that acts as a source of IPv6 multicast traffic is only an indirect participant in MLD
snooping—it just provides multicast traffic, and MLD doesn’t interact with it. (Note, however, that in an application like
desktop conferencing a network node may act as both a source and an MLD host; but MLD interacts with that node only
in its role as an MLD host.)
A source node creates multicast traffic by sending packets to a multicast address. In IPv6, addresses with the first eight
bits set (that is, “FF” as the first two characters of the address) are multicast addresses, and any node that listens to
such an address will receive the traffic sent to that address. Application software running on the source and destination
systems cooperates to determine what multicast address to use. (Note that this is a function of the application software,
not of MLD.)
When MLD snooping is enabled on a VLAN, the switch acts to minimize unnecessary multicast traffic. If the switch
receives multicast traffic destined for a given multicast address, it forwards that traffic only to ports on the VLAN that
have MLD hosts for that address. It drops that traffic for ports on the VLAN that have no MLD hosts

3.7 MVR
The MVR feature enables multicast traffic forwarding on the Multicast VLAN. In a multicast television application, a PC
or a television with a set-top box can receive the multicast stream. Multiple set-top boxes or PCs can be connected to
one subscriber port, which is a switch port configured as an MVR receiver port. When a subscriber selects a channel,
the set-top box or PC sends an IGMP join message to Switch A to join the appropriate multicast. Uplink ports that send
and receive multicast data to and from the multicast VLAN are called MVR source ports.

3.8 LLDP
The switch supports the LLDP. The Link Layer Discovery Protocol (LLDP) provides a standards-based method for enabling
switches to advertise themselves to adjacent devices and to learn about adjacent LLDP devices. The Link Layer Discovery
Protocol (LLDP) is a vendor-neutral Link Layer protocol in the Internet Protocol Suite used by network devices for advertising
their identity, capabilities, and neighbors on a IEEE 802 local area network, principally wired Ethernet. The protocol is
formally referred to by the IEEE as Station and Media Access Control Connectivity Discovery specified in standards
document IEEE 802.1AB.

Parameter description:
LLDP Parameters
Tx Interval:
The switch periodically transmits LLDP frames to its neighbors for having the network discovery information up-to-date.
The interval between each LLDP frame is determined by the Tx Interval value. Valid values are restricted to 5 - 32768
seconds.
Tx Hold:
Each LLDP frame contains information about how long the information in the LLDP frame shall be considered valid. The
LLDP information valid period is set to Tx Hold multiplied by Tx Interval seconds. Valid values are restricted to 2 - 10
times.
Tx Delay:
If some configuration is changed (e.g. the IP address) a new LLDP frame is transmitted, but the time between the LLDP
frames will always be at least the value of Tx Delay seconds. Tx Delay cannot be larger than 1/4 of the Tx Interval value.
Valid values are restricted to 1 - 8192 seconds.
Tx Reinit:
When a port is disabled, LLDP is disabled or the switch is rebooted, an LLDP shutdown frame is transmitted to the
neighboring units, signaling that the LLDP information isn't valid anymore. Tx Reinit controls the amount of seconds
between the shutdown frame and a new LLDP initialization. Valid values are restricted to 1 - 10 seconds.

Disabled The switch will not send out LLDP information, and will drop LLDP information received from neighbors.
Enabled the switch will send out LLDP information, and will analyze LLDP information received from neighbors.
CDP Aware:
Select CDP awareness.
The CDP operation is restricted to decoding incoming CDP frames (The switch doesn't transmit CDP frames). CDP frames
are only decoded if LLDP on the port is enabled.
Only CDP TLVs that can be mapped to a corresponding field in the LLDP neighbors’ table are decoded. All other TLVs
are discarded (Unrecognized CDP TLVs and discarded CDP frames are not shown in the LLDP statistics.). CDP TLVs are
mapped onto LLDP neighbors’ table as shown below.
CDP TLV "Device ID" is mapped to the LLDP "Chassis ID" field.
CDP TLV "Address" is mapped to the LLDP "Management Address" field. The CDP address TLV can contain multiple
addresses, but only the first address is shown in the LLDP neighbors’ table.
CDP TLV "Port ID" is mapped to the LLDP "Port ID" field.
CDP TLV "Version and Platform" is mapped to the LLDP "System Description" field.
Both the CDP and LLDP support "system capabilities", but the CDP capabilities cover capabilities that are not part of the
LLDP. These capabilities are shown as "others" in the LLDP neighbors’ table.
If all ports have CDP awareness disabled the switch forwards CDP frames received from neighbor devices. If at least one
port has CDP awareness enabled all CDP frames are terminated by the switch.

Parameter description:
Fast start repeat count
Rapid startup and Emergency Call Service Location Identification Discovery of endpoints is a critically important aspect
of VoIP systems in general. In addition, it is best to advertise only those pieces of information which are specifically
relevant to particular endpoint types (for example only advertise the voice network policy to permitted voice-capable
devices), both in order to conserve the limited LLDPU space and to reduce security and system integrity issues that can
come with inappropriate knowledge of the network policy.
With this in mind LLDP-MED defines an LLDP-MED Fast Start interaction between the protocol and the application layers
on top of the protocol, in order to achieve these related properties. Initially, a Network Connectivity Device will only
transmit LLDP TLVs in an LLDPDU. Only after an LLDP-MED Endpoint Device is detected, will an LLDP-MED capable
Network Connectivity Device start to advertise LLDP-MED TLVs in outgoing LLDPDUs on the associated port. The LLDP-MED
application will temporarily speed up the transmission of the LLDPDU to start within a second, when a new LLDP-MED
neighbor has been detected in order share LLDP-MED information as fast as possible to new neighbors.
Because there is a risk of an LLDP frame being lost during transmission between neighbors, it is recommended to repeat
the fast start transmission multiple times to increase the possibility of the neighbors receiving the LLDP frame. With Fast
start repeat count it is possible to specify the number of times the fast start transmission would be repeated. The
recommended value is 4 times, given that 4 LLDP frames with a 1 second interval will be transmitted, when an LLDP
frame with new information is received.
It should be noted that LLDP-MED and the LLDP-MED Fast Start mechanism is only intended to run on links between
LLDP-MED Network Connectivity Devices and Endpoint Devices, and as such does not apply to links between LAN
infrastructure elements, including Network Connectivity Devices, or other types of links.

Network Policy Discovery enables the efficient discovery and diagnosis of mismatch issues with the VLAN configuration,
along with the associated Layer 2 and Layer 3 attributes, which apply for a set of specific protocol applications on that
port. Improper network policy configurations are a very significant issue in VoIP environments that frequently result in
voice quality degradation or loss of service.
Policies are only intended for use with applications that have specific 'real-time' network policy requirements, such as
interactive voice and/or video services.
The network policy attributes advertised are:
1. Layer 2 VLAN ID (IEEE 802.1Q-2003)
2. Layer 2 priority value (IEEE 802.1D-2004)
3. Layer 3 Diffserv code point (DSCP) value (IETF RFC 2474)
This network policy is potentially advertised and associated with multiple sets of application types supported on a given
port. The application types specifically addressed are:
1. Voice
2. Guest Voice
3. Softphone Voice
4. Video Conferencing
5. Streaming Video
6. Control / Signaling (conditionally support a separate network policy for the media types above)
A large network may support multiple VoIP policies across the entire organization, and different policies per application
type. LLDP-MED allows multiple policies to be advertised per port, each corresponding to a different application type.
Different ports on the same Network Connectivity Device may advertise different sets of policies, based on the authenticated
user identity or port configuration.
It should be noted that LLDP-MED is not intended to run on links other than between Network Connectivity Devices and
Endpoints, and therefore does not need to advertise the multitude of network policies that frequently run on an aggregated
link interior to the LAN.
Delete:
Check to delete the policy. It will be deleted during the next save.
Policy ID:
ID for the policy. This is auto generated and shall be used when selecting the polices that shall be mapped to the specific
ports.
Application Type:
Intended use of the application types:
1. Voice - for use by dedicated IP Telephony handsets and other similar appliances supporting interactive voice services.
These devices are typically deployed on a separate VLAN for ease of deployment and enhanced security by isolation from
data applications.
2. Voice Signaling (conditional) - for use in network topologies that require a different policy for the voice signaling than
for the voice media. This application type should not be advertised if all the same network policies apply as those
advertised in the Voice application policy.
3. Guest Voice - support a separate 'limited feature-set' voice service for guest users and visitors with their own IP
Telephony handsets and other similar appliances supporting interactive voice services.
4. Guest Voice Signaling (conditional) - for use in network topologies that require a different policy for the guest voice
signaling than for the guest voice media. This application type should not be advertised if all the same network policies
apply as those advertised in the Guest Voice application policy.

5. Softphone Voice - for use by softphone applications on typical data centric devices, such as PCs or laptops. This class
of endpoints frequently does not support multiple VLANs, if at all, and are typically configured to use an 'untagged'
VLAN or a single 'tagged' data specific VLAN. When a network policy is defined for use with an 'untagged' VLAN (see
Tagged flag below), then the L2 priority field is ignored and only the DSCP value has relevance.
6. Video Conferencing - for use by dedicated Video Conferencing equipment and other similar appliances supporting
real-time interactive video/audio services.
7. Streaming Video - for use by broadcast or multicast based video content distribution and other similar applications
supporting streaming video services that require specific network policy treatment. Video applications relying on TCP
with buffering would not be an intended use of this application type.
8. Video Signaling (conditional) - for use in network topologies that require a separate policy for the video signaling
than for the video media. This application type should not be advertised if all the same network policies apply as those
advertised in the Video Conferencing application policy.
Tag:
Tag indicating whether the specified application type is using a 'tagged' or an 'untagged' VLAN.
Untagged indicates that the device is using an untagged frame format and as such does not include a tag header as
defined by IEEE 802.1Q-2003. In this case, both the VLAN ID and the Layer 2 priority fields are ignored and only the
DSCP value has relevance.
Tagged indicates that the device is using the IEEE 802.1Q tagged frame format, and that both the VLAN ID and the Layer
2 priority values are being used, as well as the DSCP value. The tagged format includes an additional field, known as
the tag header. The tagged frame format also includes priority tagged frames as defined by IEEE 802.1Q-2003.
VLAN ID:
VLAN identifier (VID) for the port as defined in IEEE 802.1Q-2003.
L2 Priority:
L2 Priority is the Layer 2 priority to be used for the specified application type. L2 Priority may specify one of eight priority
levels (0 through 7), as defined by IEEE 802.1D-2004. A value of 0 represents use of the default priority as defined in
IEEE 802.1D-2004.
DSCP:
DSCP value to be used to provide Diffserv node behavior for the specified application type as defined in IETF RFC 2474.
DSCP may contain one of 64 code point values (0 through 63). A value of 0 represents use of the default DSCP value as
defined in RFC 2475.

IP communication service using the LLDP-MED framework.
Within the LLDP-MED Endpoint Device category, the LLDP-MED scheme is broken into further Endpoint Device Classes,
as defined in the following.
Each LLDP-MED Endpoint Device Class is defined to build upon the capabilities defined for the previous Endpoint Device
Class. For-example will any LLDP-MED Endpoint Device claiming compliance as a Media Endpoint (Class II) also support
all aspects of TIA-1057 applicable to Generic Endpoints (Class I), and any LLDP-MED Endpoint Device claiming compliance
as a Communication Device (Class III) will also support all aspects of TIA-1057 applicable to both Media Endpoints (Class
II) and Generic Endpoints (Class I).

Policy:
Policy indicates that an Endpoint Device wants to explicitly advertise that the policy is required by the device. Can be
either Defined or Unknown
Unknown: The network policy for the specified application type is currently unknown.
Defined: The network policy is defined.
TAG:
TAG is indicative of whether the specified application type is using a tagged or an untagged VLAN. Can be Tagged or
Untagged.
Untagged: The device is using an untagged frame format and as such does not include a tag header as defined by IEEE
802.1Q-2003.
Tagged: The device is using the IEEE 802.1Q tagged frame format.
VLAN ID:
VLAN ID is the VLAN identifier (VID) for the port as defined in IEEE 802.1Q-2003. A value of 1 through 4094 is used to
define a valid VLAN ID. A value of 0 (Priority Tagged) is used if the device is using priority tagged frames as defined by
IEEE 802.1Q-2003, meaning that only the IEEE 802.1D priority level is significant and the default PVID of the ingress
port is used instead.
Priority:
Priority is the Layer 2 priority to be used for the specified application type. One of the eight priority levels (0 through 7).
DSCP:
DSCP is the DSCP value to be used to provide Diffserv node behavior for the specified application type as defined in IETF
RFC 2474. Contain one of 64 code point values (0 through 63).
3.8.5 EEE
By using EEE power savings can be achieved at the expense of traffic latency. This latency occurs due to the circuits EEE
turns off to save power, need time to boot up before sending traffic over the link. This time is called "wakeup time". To
achieve minimal latency, devices can use LLDP to exchange information about their respective tx and rx "wakeup time",
as a way to agree upon the minimum wakeup time they need.
This page provides an overview of EEE information exchanged by LLDP.

Parameter description:
Local Port:
The port on which LLDP frames are received or transmitted.
Tx Tw:
The link partner’s maximum time that transmit path can hold off sending data after reassertion of LPI.
Rx Tw:
The link partner’s time that receiver would like the transmitter to hold off to allow time for the receiver to wake from
sleep.
Fallback Receive Tw:
The link partner’s fallback receives Tw.
A receiving link partner may inform the transmitter of an alternate desired Tw_sys_tx. Since a receiving link partner is
likely to have discrete levels for savings, this provides the transmitter with additional information that it may use for a
more efficient allocation. Systems that do not implement this option default the value to be the same as that of the
Receive Tw_sys_tx.
Echo Tx Tw:
The link partner's Echo Tx Tw value.
The respective echo values shall be defined as the local link partners’ reflection (echo) of the remote link partners’
respective values. When a local link partner receives its echoed values from the remote link partner it can determine
whether or not the remote link partner has received, registered and processed its most recent values. For example, if the
local link partner receives echoed parameters that do not match the values in its local MIB, then the local link partner
infers that the remote link partners request was based on stale information.
Echo Rx Tw:
The link partner's Echo Rx Tw value.
Resolved Tx Tw:
The resolved Tx Tw for this link. Note: NOT the link partner
The resolved value that is the actual "tx wakeup time“used for this link (based on EEE information exchanged via LLDP).

3.9 Filtering Data Base
The Filtering Data Base Configuration includes many functions, including MAC Table Information, Static MAC Learning,
which cannot be categorized to some function type.
MAC table
Switching of frames is based upon the DMAC address contained in the frame. The switch builds up a table that maps
MAC addresses to switch ports for knowing which ports the frames should go to (based upon the DMAC address in the
frame). This table contains both static and dynamic entries. The static entries are configured by the network administrator
if the administrator wants to do a fixed mapping between the DMAC address and switch ports.
The frames also contain a MAC address (SMAC address ), which shows the MAC address of the equipment sending the
frame. The SMAC address is used by the switch to automatically update the MAC table with these dynamic MAC addresses.
Dynamic entries are removed from the MAC table if no frame with the corresponding SMAC address has been seen after
a configurable age time

based upon the following settings:
Auto:
Learning is done automatically as soon as a frame with unknown SMAC is received.
Disable:
No learning is done.
Secure:
Only static MAC entries are learned, all other frames are dropped.

3.10 VLAN
How to assign a specific VLAN for management purposes
The management VLAN is used to establish an IP connection to the switch from a workstation connected to a port in
the VLAN. This connection supports a VSM, SNMP, Telnet, HTTP(S) and SSH session. By default, the active management
VLAN is VLAN 1, but you can designate any VLAN as the management VLAN using the management VLAN window. Only
one management VLAN can be active at a time.
When you specify a new management VLAN, your connection to the old management VLAN is lost. For this reason, you
should have a connection between your management station and a port in the new management VLAN or connect to
the new management VLAN through a multi-VLAN route.
3.10.1 VLAN Membership

configurations such as PVID and UVID. Currently we support the following VLAN user types:
Web/SNMP: These are referred to as static.
NAS: NAS provides port-based authentication, which involves communications between a Supplicant, Authenticator,
and an Authentication Server.
MVRP: Multiple VLAN Registration Protocol (MVRP) allows dynamic registration and deregistration of VLANs on ports
on a VLAN bridged network.
GVRP: GARP VLAN Registration Protocol (GVRP) allows dynamic registration and deregistration of VLANs on ports on a
VLAN bridged network.
Voice VLAN: Voice VLAN is a VLAN configured specially for voice traffic typically originating from IP phones.
MVR: MVR is used to eliminate the need to duplicate multicast traffic for subscribers in each VLAN. Multicast traffic for
all channels is sent only on a single (multicast) VLAN.
MSTP: The 802.1s Multiple Spanning Tree protocol (MSTP) uses VLANs to create multiple spanning trees in a network,
which significantly improves network resource utilization while maintaining a loop-free environment.

3.10.5 Private VLANs
In a private VLAN, communication between ports in that private VLAN is not permitted. Any VLAN can be configured as
a private VLAN.
Private VLAN Membership
The Private VLAN membership configurations for the switch can be monitored and modified here. Private VLANs can be
added or deleted here. Port members of each Private VLAN can be added or removed here.
Private VLANs are based on the source port mask, and there are no connections to VLANs. This means that VLAN IDs
and Private VLAN IDs can be identical.
A port must be a member of both a VLAN and a Private VLAN to be able to forward packets. By default, all ports are
VLAN unaware and members of VLAN 1 and Private VLAN 1.
A VLAN unaware port can only be a member of one VLAN, but it can be a member of multiple Private VLANs.

Port Isolation
Port Isolation provides for an apparatus and method to isolate ports on layer 2 switches on the same VLAN to restrict
traffic flow. The apparatus comprises a switch having said plurality of ports, each port configured as a protected port or
a non-protected port. An address table memory stores an address table having a destination address and port number
pair. A forwarding map generator generates a forwarding map which is responsive to a destination address of a data
packet. The method for isolating ports on a layer 2 switch comprises configuring each of the ports on the layer 2 switch
as a protected port or a non-protected port. A destination address on an data packet is matched with a physical address
on said layer 2 switch and a forwarding map is generated for the data packet based upon the destination address on
the data packet. The data packet is then sent to the plurality of ports pursuant to the forwarding map generated based
upon whether the ingress port was configured as a protected or non-protected port.
This page is used for enabling or disabling port isolation on ports in a Private VLAN.A port member of a VLAN can be

3.10.6 MAC-based VLAN
MAC address-based VLAN decides the VLAN for forwarding an untagged frame based on the source MAC address of
the frame.
The most common way of grouping VLAN members is by port, hence the name port-based VLAN. Typically, the device
adds the same VLAN tag to untagged packets that are received through the same port. Later on, these packets can be
forwarded in the same VLAN. Port-based VLAN is easy to configure, and applies to networks where the locations of
terminal devices are relatively fixed. As mobile office and wireless network access gain more popularity, the ports that
terminal devices use to access the networks are very often non-fixed. A device may access a network through Port A this
time, but through Port B the next time. If Port A and Port B belong to different VLANs, the device will be assigned to a
different VLAN the next time it accesses the network. As a result, it will not be able to use the resources in the old VLAN.
On the other hand, if Port A and Port B belong to the same VLAN, after terminal devices access the network through
Port B, they will have access to the same resources as those accessing the network through Port A do, which brings
security issues. To provide user access and ensure data security in the mean time, the MAC-based VLAN technology is
developed.
MAC-based VLANs group VLAN members by MAC address. With MAC-based VLAN configured, the device adds a VLAN
tag to an untagged frame according to its source MAC address. MAC-based VLANs are mostly used in conjunction with
security technologies such as 802.1X to provide secure, flexible network access for terminal devices.
Configuration

3.10.7 Protocol-based VLAN
This section describe Protocol-based VLAN. The Switch supports protocols including Ethernet, LLC, and SNAP.
LLC
The Logical Link Control (LLC) data communication protocol layer is the upper sub-layer of the Data Link Layer (which is
itself layer 2, just above the Physical Layer) in the seven-layer OSI reference model. It provides multiplexing mechanisms
that make it possible for several network protocols (IP, IPX, Decnet and Appletalk) to coexist within a multipoint network
and to be transported over the same network media, and can also provide flow control and automatic repeat request (ARQ)
error management mechanisms.
SNAP
The Sub-network Access Protocol (SNAP) is a mechanism for multiplexing, on networks using IEEE 802.2 LLC, more
protocols than can be distinguished by the 8-bit 802.2 Service Access Point (SAP) fields. SNAP supports identifying
protocols by Ethernet type field values; it also supports vendor-private protocol identifier spaces. It is used with IEEE
802.3, IEEE 802.4, IEEE 802.5, IEEE 802.11 and other IEEE 802 physical network layers, as well as with non-IEEE 802
physical network layers such as FDDI that use 802.2 LLC.

type you selected.
Value:
Valid value that can be entered in this text field depends on the option selected from the preceding Frame Type selection
menu.
Below are the criteria for three different Frame Types:
For Ethernet: Values in the text field when Ethernet is selected as a Frame Type is called etype. Valid values for etype
ranges from 0x0600-0xffff
For LLC: Valid value in this case is comprised of two different sub-values. a. DSAP: 1-byte long string (0x00-0xff) b. SSAP:
1-byte long string (0x00-0xff)
For SNAP: Valid value in this case also is comprised of two different sub-values. a. OUI: OUI (Organizationally Unique
Identifier) is value in format of xx-xx-xx where each pair (xx) in string is a hexadecimal value ranges from 0x00-0xff. b.
PID: If the OUI is hexadecimal 000000, the protocol ID is the Ethernet type (EtherType) field value for the protocol running
on top of SNAP; if the OUI is an OUI for a particular organization, the protocol ID is a value assigned by that organization
to the protocol running on top of SNAP. In other words, if value of OUI field is 00-00-00 then value of PID will be etype
(0x0600-0xffff) and if value of OUI is other than 00-00-00 then valid value of PID will be any value from 0x0000 to 0xffff.
Group Name:
A valid Group Name is a unique 16-character long string for every entry which consists of a combination of alphabets
(a-z or A-Z) and integers (0-9).

3.12 GARP
The Generic Attribute Registration Protocol (GARP) provides a generic framework whereby devices in a bridged LAN,
e.g. end stations and switches, can register and de-register attribute values, such as VLAN Identifiers, with each other.
In doing so, the attributes are propagated to devices in the bridged LAN, and these devices form a "reachability"-tree
that is a subset of an active topology. GARP defines the architecture, rules of operation, state machines and variables
for the registration and de-registration of attribute values.
A GARP participation in a switch or an end station consists of a GARP application component, and a GARP Information
Declaration (GID) component associated with each port or the switch. The propagation of information between GARP
participants for the same application in a bridge is carried out by the GARP Information Propagation (GIP) component.
Protocol exchanges take place between GARP participants by means of LLC Type 1 services, using the group MAC address
and PDU format defined for the GARP application concerned.

GVRP is an application based on Generic Attribute Registration Protocol (GARP), mainly used to automatically and
dynamically maintain the group membership information of the VLANs. The GVRP offers the function providing the VLAN
registration service through a GARP application. It makes use of GARP Information Declaration (GID) to maintain the
ports associated with their attribute database and GARP Information Propagation (GIP) to communicate among switches
and end stations. With GID information and GIP, GVRP state machine maintain the contents of Dynamic VLAN Registration
Entries for each VLAN and propagate these information to other GVRP-aware devices to setup and update their knowledge
database, the set of VLANs associated with currently active members, and through which ports these members can be
reached.
