Chapter 1 Operation of Web-based Management
Initial Configuration
This chapter instructs you how to configure and manage the LGB5128A through the Web user interface. With this facility, you can easily access and monitor status of all switches through any one port of the switch, including MIBs status, each port activity, Spanning tree status, port aggregation status, multicast traffic, VLAN and priority status, illegal access record, and so on.
The default values of the LGB5128A are listed in the table below:
IP Address
192.168.1.1
Subnet Mask
255.255.255.0
Default Gateway
192.168.1.254
Username
admin
Password
After the LGB5128A has finished configuring the IT interface, you can browse it. For instance, if you type http://192.168.1.1 in the address row in a browser, it will show the following screen and ask you to input a username and password to login and access authentication.
The default username is “admin” and the default password is empty. The first time you access the switch, enter the default username and password, and then click the <Login> button. The login process now is completed. In this login menu, you have to input the complete username and password respectively; the LGB5128A will not give you a shortcut to username automatically. This looks inconvenient, but is safer.
The LGB5128A supports a simple user management function allowing only one administrator to configure the system at a time. If there are two or more users using administrator’s identity, it will allow the only the user who logs in first to configure the system. The rest of users, even with administrator’s identity, can only monitor the system. Users who have no administrator’s identity can only monitor the system. A maximum of three users can login simultaneously to the LGB5128A.
NOTE:
When you login the Switch WEB/CLI to manager, you must first type the Username of the admin. The password is blank, after you type in the end Username, press enter. When the management page appears, you can enter WEB/CLI.
When you login LGB5128A series switch Web UI management, you can use both ipv4 ipv6 login to manage the switch.
To optimize the display effect, we recommend you use Microsoft IE 6.0 or above, Netscape V7.1 or above, or FireFox V1.00 or above and select the resolution as 1024 x 768. The switch supports a neutral Web browser interface.

NOTE:
DHCP is enabled on the LGB5128A, but if you do not have a DHCP server to provide IP addresses to the switch, use the switch
default ip 192.168.1.1

Select the clock source for the LGB5128A. You can choose “Use local Settings” or “Use NTP Server” for the LGB5128A time clock source.
Local Time:
Shows the current time of the system.
Time Zone Offset:
Provides the timezone offset relative to UTC/GMT. The offset is given in minutes east of GMT. The valid range is from -720 to +720 minutes.
Daylight Saving:
Daylight saving is used in some countries. If set, it will adjust the time lag or advance in unit of hours, according to the starting date and the ending date. For example, you can set the daylight saving to be 1 hour. When the time passes over the starting time, the system time will be increased one hour after one minute at the time since it passed over. When the time passes over the ending time, the system time will be decreased one hour after one minute at the time since it passed over.
The switch supports valid configurable daylight saving times between –5 and +5 steps for one hour. If this parameter is zero, the switch enacts daylight saving time. You don’t have to set the starting/ending date as well. If you set daylight saving to be non-zero, you have to set the starting/ending date as well; otherwise, the daylight saving function will not be activated.

2-2.2 NTP
NTP is Network Time Protocol and is used to sync the network time based on 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 in shortly after pressing <Apply> button. Though it synchronizes the time automatically, NTP does not update the time periodically without user’s processing.
Time Zone is an offset time off GMT. You have to select the time zone first and then perform time sync via NTP, because the switch will combine this time zone offset and updated NTP time to result in the local time; otherwise, you will not able to get the correct time. The switch supports configurable time zone from –12 to +13 step 1 hour.
Default Time zone: +8 Hrs.

2-4 IP
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 assured 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 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 IPV4
You can obtain the IPv4 address for the switch 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 establish a default gateway between the switch and management stations that exist on another network segment.

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. The SNMP agent running on the switch responds to the request issued by SNMP manager.
Basically, it 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 to “Enable”, the SNMP agent will start up. All supported MIB OIDs, including RMON MIB, can be accessed via SNMP manager. If the field SNMP is set “Disable,” the SNMP agent will be de-activated, and the related Community Name, Trap Host IP Address, Trap, and all MIB counters will be ignored.
2-6.1 System
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 on the <Apply> button, and the setting takes effect.

3-1.7 EEE
The section describes how the user can 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 use (or no traffic).
EEE works by powering down circuits when there is no traffic. When a port has 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 µs for 1Gbit links and 30 µs 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.
To maximize power saving, the circuit isn't started when transmit data are ready for a port, but is instead queued until 3000 bytes of data are ready to be transmitted. This does not introduce a large delay if data less then 3000 bytes shall be transmitted, and data are always transmitted after 48 us, giving a maximum latency of 48 us + the wakeup time.
If desired, you can 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 has 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. Choose the port that wants to enable the EEE function.
3. EEE Urgent Queues level and the range from 1 to 8. The queue will

3-2 ACL
The LGB5128A switch access control list (ACL) is probably the most commonly used object in the IOS. 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.

3-2.3 Access Control List
The 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. The reserved ACEs used for internal protocol, cannot be edited or deleted, the order sequence cannot be changed an the priority is highest.

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 apply 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 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 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 logical “trunked port.” The benefit of using the 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 aggregate together to form a “logic trunked port”. Using Static Trunk on both ends of a link is strongly recommended.
NOTE: 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 logical “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.
3-3.2.1 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 that 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) that 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 that 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.
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.

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, you can enter a user-defined value. 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 the priority of ports having an identical port cost. (See above).
operEdge (state flag) :
Operational flag describes 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 states 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 BPDUs are received on the port or not.

Restricted Role :
If enabled, this 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 fromj influencing 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 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 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 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.

Priority has the same definition as in the RSTP specification. But in MSTP, this parameter can be respectively applied to ports of CIST and ports of any MSTI.
Admin Edge :
Scroll this parameter to select “Edge/Non-Edge.”
If user selects “Edge,” this port will be an edge port. An Edge Port is a port connected to a device that knows nothing about STP or RSTP. Usually, the connected device is an end station. Edge Ports will immediately transit to forwarding state and skip the listening and learning state because the edge ports cannot create bridging loops in the network. This will expedite the convergence. When the link on the edge port toggles, the STP topology remains unchanged. Unlike the designated port or root port though, an edge port will transit to a normal spanning-tree port immediately if it receives a BPDU.
Default: Edge.
Admin P2P :
Scroll this parameter to select “Auto/Force True/Force False.”
We say a port is a point-to-point link, from RSTP’s view, if it is in full-duplex mode, but is a shared link if it is in half-duplex mode. RSTP fast convergence can only happen on point-to-point links and on edge ports. This can expedite the convergence because this will fast transition the port to forwarding state.
There are three parameters, Auto, Force True, and Force False, used to configure the type of the point-to-point link. If configure this parameter to be Auto, it means RSTP will use the duplex mode resulting from the auto­negotiation. In today’s switched networks, most links are running in full-duplex mode. The result may be half-duplex, in this case, the port will not fast transition to Forwarding state. If it is set as True, the port is treated as point­to-point link by RSTP and unconditionally transitioned to Forwarding state. If it is set as False, fast transition to Forwarding state will not happen on this port.
Default: Auto

3-6 IGMP Snooping
The function is used to establish the multicast groups to forward multicast packets to the member ports, and 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 distinguish multicast packets from broadcast packets, 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 forwarding.
IGMP Snooping includes query, report and leave functions. 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 previously joined in a specified IP multicast group.
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 IGMP Port Group Filtering. With the IGMP filtering feature, a user can exert this type of control. In some network application environments, such as metropolitan or multiple-dwelling unit (MDU) installations, a user might want to control the multicast groups that a user on a switch port can belong to. 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 can configure SSM for arbitrary IP multicast addresses also.

3-6 MLD Snooping
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: A application such as 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: 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. 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.
3-8.1 LLDP Configuration
Per port, you can configure the LLDP and the detail parameters, and the settings will take effect immediately. This page allows the user to inspect and configure the current LLDP port settings.
Web Interface
To configure LLDP:
1.Click LLDP configuration.
2.Modify 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 3-8.1: The LLDP Configuration
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.
Page 98
LGB5128A User Manual
88
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 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.
LLDP Port Configuration
The LLDP port settings relate to the currently selected stack unit, as reflected by 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.
