Chapter 1: Overview
1.1 Initial Configuration
This section details how to configure and manage the PoE+ Gigabit Managed Switch Eco through the Web user interface. This
feature enables administrators to easily access and monitor the entire status of the switch through any one port of the switch.
Statuses which may be monitored include status of the MIBs, activity of each port, status of spanning trees, port aggregation
status, multicast traffic, VLAN and priority status, even illegal access records.
The default values of the PoE+ Gigabit Managed Switch Eco are listed in the table below:
Table 1-1: Using Web-based management.
IP Address 192.168.1 .1
Subnet Mask
255.255.255.0
Default
Username
Password
192.168.1.25 4
admin
After the PoE+ Gigabit Managed Switch Eco has been configured in the interface, you can browse it. For instance, type
http://192.168.1.1 in the address row in a browser. You will see the screen in Figure 1-1, requesting your username and password
to log in and authenticate your access.
Figure 1-1. The login screen.
The default username is “admin” and password is empty. For the first use, please enter the default username and
password, then click the <Login> button.

LPB 2810A
Chapter 1: Overview
The login process now is completed. In this login menu, you must input the complete username and password respectively: the
PoE+ Gigabit Managed Switch Eco will not give you a shortcut to username automatically. This may be inconvenient, but it is
safer.
The PoE+ Gigabit Managed Switch Eco supports a simple user management function allowing only one administrator to configure
the system at the same time. If there are two or more users using an administrator’s identity, it will only allow the one who logs
in first to configure the system. The rest of the users, even with an administrator’s identity, can only monitor the system. Those
who have no administrator’s identity can only monitor the system. There is a maximum of three users able to login simultaneously
in the PoE+ Gigabit Managed Switch Eco.
NOTE: When you log in to the Switch Web Manager, you must first type the Username of the admin. The password must remain
blank at this point, so simply press Enter. When you log in the PoE+ Gigabit Managed Switch Eco Web UI management, you can
use either an ipv4 or ipv6 log in. To optimize the display, we recommend you use Microsoft® Internet Explorer® 6.0 or higher,
Netscape® V7.1 or higher, or FireFox® V1.00 above and set the resolution 1024x768. The switch supports a neutral Web browser
interface.
NOTE: the PoE+ Gigabit Managed Switch Eco enables the DHCP function, so if you do not have DHCP server to provide IP
addresses to the switch, the switch default IP is 192.168.1.1.
NOTE: If you need to configure the function or parameter, refer to those sections in the User Guide. Or, access the switch and
click the “help“ under the Web GUI, and the switch will open its easy-to-use help content to teach you how to set the parameters, as shown in Figure 1-2.

Connecting Network Devices
The switch is designed to be connected to 10-, 100-, or 1000-Mbps 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.
Twisted-Pair Devices
Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use Category 5, 5e, or 6 cable
for 1000BASE-T connections, Category 5 or better for 100BASE-TX connections.
Cabling Guidelines
The RJ-45 ports on the switch support automatic MDI/MDI-X pinout 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 Section 4.2 of the LPB2810A Quick Start Guide, “Ethernet Cabling,“ for more information on cabling.
CAUTION: Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-pair cables with
RJ-45 connectors that conform to FCC standards.

LPB 2810A
Chapter 1: Overview
1.2 Connecting to PCs, Servers, Hubs, and Switches
Step 1: Attach one end of a twisted-pair cable segment to the device's RJ-45 connector.
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 Section 1.3, “Network Wiring Connections.”) Otherwise,
attach the other end to an available port on the switch. Make sure each twisted-pair cable does not exceed 328 feet
(100 m) in length.
NOTE: Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise
backpressure 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.

1.3 Network Wiring Connections
Today, the punchdown 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:

Chapter 2: System Configuration
• Daylight Savings: Daylight savings time is used in some countries. If you select this setting, the unit will adjust the time, for-
ward or backward in increments of one hour, between the starting date and the ending date that you select. For example, if
you set the daylight savings offset to be 1 hour, when the time reaches the starting time, the system time will be increased one
hour. And when the time reaches the ending time, the system time will be decreased one hour.
The switch supports valid configurable daylight savings times of –5 to +5 hours in one-hour increments. The zero for this
parameter means you will not have to adjust the current time to enact daylight saving. However, remember that if you do set
the unit to observe daylight savings time, you will need to set the starting/ending date as well. If you do not set the start/end
dates, the daylight savings function will not be activated.
• Time Set Offset: Provide the daylight saving time set offset in this space. The offset is given in minutes east of GMT. The valid
range is from 1 to 1440 minutes. The default is 60 minutes.
• Daylight Savings Type: Provide the daylight savings type selection. You can select “By Dates” or “Recurring” type for Daylight
saving type.
• From: To configure when daylight savings start date and time, the format is “YYYY-MMDD HH:MM”.
• To: To configure when daylight savings end date and time, the format is “YYYY-MMDD HH:MM”.

2.2.2 NTP
NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean Time (GMT). If you 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 a short time after pressing yjr <Apply> button. Although it synchronizes the time automatically, NTP does not
update the time periodically without user input.
Time Zone is an offset time of 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 the updated NTP time to calculate the local time; otherwise, you will not able to get
the correct time. The switch supports configurable time zones from –12 to +13 step in one-hour increments.
Default Time zone: +8 Hrs.
Web Interface
To configure Time in the Web interface:
1. Click SYSTEM, NTP.
2. Specify the Time parameter in manual parameters.
3. Click Save.
Figure 2-5: The NTP configuration screen.
Parameter Description
• Server 1 to 5: Provide the NTP IPv4 or IPv6 address of this switch. IPv6 address is in 128-bit records represented as eight fields
of up to four hexadecimal digits with a colon separating each field (:). For example, in “fe80::215:c5ff:fe03:4dc7“, the symbol
“::“ is a special syntax that can be used as a shorthand way of representing multiple 16-bit groups of contiguous zeros; but it
can only appear once. It can also represent a legally valid IPv4 address. For example, “::192.1.2.34“.
• Buttons: These buttons are displayed on the NTP page:
- Save: Click to save changes
- Reset: Click to undo any changes made locally and revert to previously saved values.
2.3 Account
Only an administrator can create, modify, or delete the username and password. An administrator can modify other guest
identities’ passwords without confirming the password, but it is necessary to modify the administrator-equivalent identity. A
Guest-equivalent identity can modify his password only. Please note that you must confirm administrator/guest identity in the field
“Authorization in advance” before configuring the username and password. Only one administrator is permitted to exist and is
unable to be deleted. In addition, up to 4 guest accounts may be created.

• Privilege Level: The privilege level of the user. The range is 1 to 15. A privilege level value of 15 may access all groups, i.e. it is
a privilege level that is granted the full control of the device. For other users, the privilege level should be the same as or greater
than the group privilege level to have the access of that group. By default setting, most groups will have a privilege level 5,
granting read-only access; a privilege level of 10 has the read-write access. For system maintenance (software uploads, factory
defaults and etc.) users will need to have a user privilege level 15. Generally, the privilege level 15 can be used for an administrator account, privilege level 10 for a standard user account and privilege level 5 for a guest account.

2.4 IP (Internet Protocol)
IP is an acronym for Internet Protocol. It is a protocol used for communicating data across an Internet network.
IP is a "best effort" system, which means that no packet of information sent over is ensured to reach its destination in the same
condition it was sent. Each device connected to a Local Area Network (LAN) or Wide Area Network (WAN) is given an Internet
Protocol address, and this IP address is used to identify the device uniquely among all other devices connected to the extended
network.
The current version of the Internet protocol is IPv4, which has 32-bits Internet Protocol addresses allowing for in excess of four
billion unique addresses. This number is reduced drastically by the practice of Webmasters taking addresses in large blocks, the
bulk of which remain unused. There is a rather substantial movement to adopt a new version of the Internet Protocol, IPv6, which
would have 128-bits Internet Protocol addresses. This number can be represented roughly by a three with thirty-nine zeroes after
it. However, IPv4 is still the protocol of choice for most of the Internet.
2.4.1 IP v4
The IPv4 address for the switch could be obtained via DHCP Server for VLAN 1. To manually configure an address, you need to
change the switch's default settings to values that are compatible with your network. You may also need to a establish a default
gateway between the switch and management stations that exist on another network segment.
Configure the switch-managed IP information on this page.
The Configured column is used to view or change the IP configuration.
The Current column is used to show the active IP configuration.
Web Interface
To configure an IP address in the Web interface:

2.6 SNMP
Any Network Management System (NMS) running the Simple Network Management Protocol (SNMP) can manage the managed
devices equipped with SNMP agent, provided that the Management Information Base (MIB) is installed correctly on the managed
devices. The SNMP is a protocol that is used to govern the transfer of information between SNMP manager and agent and
traverses the Object Identity (OID) of the management Information Base (MIB), described in the form of SMI syntax. SNMP agent
is running on the switch to responsd to the request issued by SNMP manager.
Essentially, SNMP is passive except for issuing the trap information. The switch supports a switch to turn on or off the SNMP
agent. If you set the field SNMP “Enable”, SNMP agent will start. All supported MIB OIDs, including RMON MIB, can be accessed
via SNMP manager. If the field SNMP is set “Disable,” SNMP agent will be de-activated, the related Community Name, Trap Host
IP Address, Trap, and all MIB counters will be ignored.
2.6.1 Sys tem
This section describes how to configure SNMP System on the switch. This function is used to configure SNMP settings, community
name, trap host, and public traps as well as the throttle of SNMP. A SNMP manager must pass the authentication by identifying
both community names, then it can access the MIB information of the target device. So, both parties must have the same
community name. Once completing the setting, click the <Apply> button, and the setting takes effect.

3.1.7 EEE
This section enables the user to inspect and configure the current EEE port settings.
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 called “wakeup time.“ The default wake-up time is 17 µs for 1 Gb links and 30 µs
for other link speeds. EEE devices must agree upon the value of the wakeup time to make sure that both the receiving device and
the transmitting device have 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 savings, the circuit isn’t started at once. Data is made ready, and is queued until 3000 bytes of data are
ready to be transmitted. In order not to introduce a large delay in case data less than 3000 bytes needs to be transmitted, data is
always transmitted after 48 µs, giving a maximum latency of 48 µs plus the wakeup time.
It is possible to minimize the latency for specific frames by mapping the frames to a specific queue (done with QOS) and then to
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.
Web Interface
To configure the EEE Configuration in the Web interface:
1. Click Configuration, Port, then EEE.
2. Select which port needs the EEE function enabled.
3. The EEE Urgent Queues level ranges from 1 to 8. The queue will postpone the transmsion until 3000 bytes are ready to be

3.2 ACL
The PoE+ Gigabit Managed Switch Eco access control list (ACL) is probably the most commonly used object in the IOS. It is used
not only 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 go over the standard and extended
access lists for TCP/IP. To create ACEs for ingress classification, assign a policy for each port. The policy numbers are 1-8, but, 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
This section describes how to configure the ACL parameters (ACE) of each switch port. These parameters will affect frames
received on a port unless the frame matches a specific ACE.

This section describes how to configure Access Control List rule. 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.

3.3 Aggregation
The Aggregation 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 use your current Ethernet equipment 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.
3.3.1 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 aggregated together to form a “logic trunked port”. Black Box strongly recommends using Static Trunk on both ends of a link.
NOTE: Low speed links will stay in a “not ready” state when using static trunk to aggregate with high speed links.
Web Interface
To configure the Trunk Aggregation Hash mode and Aggregation Group in the Web interface:
1. Click Configuration, Static Trunk, and then Aggregation Mode Configuration.
2. Click “Evoke Aggregation Group ID and Port members“ to enable or disable the aggregation mode function.

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.
Configuration
This page allows the user to inspect the current LACP port configurations, and possibly change them as well. An LACP trunk
group with more than one ready member-ports is a “real trunked” group. An LACP trunk group with only one or less than one
ready member-ports is not a “real trunked” group.

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 uses a distributed algorithm to select a bridging device (an 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.
Figure 3-17. The Spanning Tree protocol.
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
Basic Settings
• Protocol Version: The STP protocol version setting. Valid values are STP, RSTP, and MSTP.
• Bridge Priority: Controls the bridge priority. Lower numeric values have better priority. The bridge priority plus the MSTI
instance number, concatenated with the 6-byte MAC address of the switch, forms a Bridge Identifier. For MSTP operation, this
is the priority of the CIST. Otherwise, this is the priority of the STP/RSTP bridge.
• Forward Delay: The delay used by STP Bridges to transit Root and Designated Ports to Forwarding (used in STP compatible
mode). Valid values are in the range 4 to 30 seconds.
• Max Age: The maximum age of the information transmitted by the Bridge when it is the Root Bridge. Valid values are in the
range 6 to 40 seconds, and MaxAge must be <= (FwdDelay-1)*2.
• Maximum Hop Count: Defines the initial value of remaining Hops for MSTI information generated at the boundary of an MSTI
region, or how many bridges a root bridge can distribute its BPDU information to. Valid values are in the range 6 to 40 hops.
• Transmit Hold Count: The number of BPDU's a bridge port can send per second. When exceeded, transmission of the next
BPDU will be delayed. Valid values are in the range 1 to 10 BPDUs per second.

• Edge Port BPDU Guard: Control whether a port explicitly configured as Edge will disable itself upon reception of a BPDU. The
port will enter the error-disabled state, and will be removed from the active topology.
• Port Error Recovery: Control whether a port in the error-disabled state automatically will be enabled after a certain time. If
recovery is not enabled, ports have to be disabled and re-enabled for normal STP operation. The condition is also cleared by a
system reboot.
• Port Error Recovery Timeout: The time to pass before a port in the error-disabled state can be enabled. Valid values are

3.4.2. MSTI Mapping
When you implement a Spanning Tree protocol on the switch, the CIST is not available for explicit mapping, because it receives
the VLANs that are not explicitly mapped. For this reason, you need to set the list of VLANs mapped to the MSTI. The VLANs
must be separated with a comma and/or a space. A VLAN can only be mapped to one MSTI. An unused MSTI should simply be
left empty, (i.e. with no VLANs mapped to it.)
This section describes it allows the user to inspect the current STP MSTI bridge instance priority configurations, and possibly
change them as well.

Chapter 3: Configuration
• Priority: Controls the port priority. This can be used to control priority of ports having identical port cost. (See 3.4.3 MSTI
Priorities).
• operEdge (state flag): This is the operational flag describing whether the port is connecting directly to edgedevices. (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: This controls whether the operEdge flag should start as set or cleared (the initial operEdge state when a port is
initialized).
• AutoEdge: This setting controls whether the bridge should enable automatic edge detection on the bridge port. This allows
operEdge to be derived from whether BPDUs are received on the port or not.
• Restricted Role: If enabled, this setting 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, this setting 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, this setting causes the port to disable itself upon receiving valid BPDUs. Contrary to the similar bridge
setting, the port edge status does not affect this setting. A port entering error-disabled state because of 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 Loop Detection
Loop detection is used to detect the presence of traffic. When a switch receives a packet’s (looping detection frame) MAC
address that’s the same as the MAC address from the port, loop detection occurs. The port will be locked when it receives the
looping detection frames. To restore the locked port, delete the looping path, then click on “Resume.”

3.6 IGMP Snooping
This function is used to establish the multicast groups to forward the multicast packet to the member ports, and, in doing so,
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 cannot tell the multicast packet from the broadcast packet, so it can only treat them all as
broadcast packets. Without IGMP Snooping, the multicast packet forwarding function is plain, and nothing is different from
broadcast packet.
A switch-supported 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.

3.6.3 Port Group Filtering
This section describes how to set the IGMP Port Group Filtering. In some network application environments, such as 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. This feature 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.

3.6.6 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 can
configure SSM for arbitrary IP multicast addresses also.

3.7 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.

3.9 LLDP
The switch supports the LLDP. For current information on your switch model, 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.
3.9.1 LLDP Configuration
When you change LLDP configuration and the detail parameters, the settings will take effect immediately. This page enables you
to view and configure the current LLDP port settings.
Web Interface
To configure LLDP:
1. Click LLDP configuration.
2. Modify the LLDP timing parameters.
3. Set the required mode for transmitting or receiving LLDP messages.
4. Specify the information to include in the TLV field of advertised messages.
5. Click Save.
Figure 3-43: The LLDP Configuration screen.
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 five to 32768
seconds.
• Tx Hold : Each LLDP frame contains information about how long the information in the LLDP frame will be considered valid. The
LLDP information valid period is set to Tx Hold multiplied by Tx Interval seconds. Valid values are restricted to two to 10 times.
Page 92
724-746-5500 | blackbox.com
LPB 2810A
Chapter 3: Configuration
• 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 one to 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 one to 10 seconds.
LLDP Port Configuration
The LLDP port settings relate to the one that is currently selected, as shown in the page header.
• Port: The switch port number of the logical LLDP port.
• Mode: Select LLDP mode.
- Rx only: The switch will not send out LLDP information, but LLDP information from neighbor units is analyzed.
- Tx only: The switch will drop LLDP information received from neighbors, but will send out LLDP information.
- 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.
NOTE: When CDP awareness on a port is disabled, CDP information isn’t removed until the hold time is exceeded.
• Port Descr: Optional TLV: When checked the “port description“ is included in LLDP information.
• Sys Name: Optional TLV: When checked the “system name“ is included in LLDP information.
• Sys Descr: Optional TLV: When checked the “system description“ is included in LLDP information.
• Sys Capa: Optional TLV: When checked the “system capability“ is included in LLDP information.
• Mgmt Addr: Optional TLV: When checked the “management address“ is included in LLDP information.

Parameter Description Fast Start Repeat Count
The Rapid startup and Emergency Call Service Location Identification Discovery of endpoints are critically important aspects of
VoIP systems. It is best to advertise only those pieces of information that are specifically relevant to particular endpoint types (for
example only advertise the voice network policy to permitted voice-capable devices), both 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 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 to 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, Black Box recommends that you
repeat the fast start transmission multiple times to increase the possibility of the neighbors receiving the LLDP frame. With the fast
start repeat count selection, 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.
NOTE: The LLDP-MED and the LLDP-MED Fast Start mechanism are only intended to run on links between LLDP-MED Network
connectivity Devices and Endpoint Devices, and as such do not apply to links between LAN infrastructure elements, including
network connectivity devices, or other types of links.

Parameter Configuration:
Policies: 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. Videoconferencing
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.
NOTE: 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 should be used when selecting the polices that are mapped to the
specific ports.

Chapter 3: Configuration
• Application Type: Intended use of the application types:
1. Voice - for use by dedicated IP telephony handsets and 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
end points 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. Videoconferencing - for use by dedicated videoconferencing 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 behaviour 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.
• Adding a new policy: Click to add a new policy. Specify the Application type, Tag, VLAN ID, L2 Priority and DSCP for the new
policy. Click “Save.“
• Port Policies Configuration: Every port may advertise a unique set of network policies or different attributes for the same
network policies, based on the authenticated user identity or port configuration.
• Port: The port number to which the configuration applies.
• Policy ID: The set of policies that apply to a given port. Set policies by checking the corresponding checkboxes.
• Buttons: “Save“: Click to save changes; “Reset“: Click to undo any changes made locally and revert to previously saved values.

Parameter Description
• Port: The port on which the LLDP frame was received.
• Device Type:
- LLDP-MED Devices are comprised of two primary Device Types: Network Connectivity Devices and Endpoint Devices.
- LLDP-MED Network Connectivity Devices, as defined in TIA-1057, provide access to the IEEE 802-based LAN infrastructure for
LLDP-MED Endpoint Devices. An LLDP-MED Network Connectivity Device is a LAN access device based on any of the following
technologies:
1. LAN Switch/Router
2. IEEE 802.1 Bridge
3. IEEE 802.3 Repeater (included for historical reasons)
4. IEEE 802.11 Wireless Access Point
5. Any device that supports the IEEE 802.1AB and MED extensions defined by TIA-1057 and can relay IEEE 802 frames via any
method.
• LLDP-MED Endpoint Device Definition:
LLDP-MED Endpoint Devices, as defined in TIA-1057, are located at the IEEE 802 LAN network edge, and participate in 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).
