1 Product Introduction

Thank you and congratulations on your purchase of D-Link Smart Managed Switch Products. D-Link's next generation S mart Managed switch serie s blends p lug-and-play simplic ity with exceptiona l valu e

and reliability for small an d m edium-sized business ( SMB) net work ing. All m odels are housed in a n ew st yle rack-mount metal case with easy-to-view front panel diagnostic LEDs, and provides advanced features including network security, traffic segmentation, QoS and versatile management.

Flexible Port Configurations. The DGS-1210 series is the new generation of Smart Managed Switch series. It provides 8, 16, 24 or 48 10/100/1000Mbps Non-PoE or PoE ports plus 4 GE/SFP ports. All switches o f th e DGS-1210 series feature e mbedded 4 gigab it SFP uplink s, which pro vides flexibl e network topol ogy choices such as ring, tree, or mixed.

D-Link Green Technology. D-Link Green devices are about providing eco-friendly alternatives without compromising perf ormance. D-Link Green T echnology includes a number of inn ovations to reduce energy consumption on DGS-1210 series such as shutting down a port, or turning off some LED indicators, or adjusting the power usage according to the Ethernet cable connected to it.

Extensive Layer 2 Featu res. Im plemented as complete L2 devices, these switc hes include functions such as IGMP snooping, port mirroring, Spanning Tree, 802.3ad LACP and Loopback Detection to enhance performance and network resiliency.

Traffic Segmentation, QoS and Auto Surveillance VLAN. The switches support 802.1Q VLAN standard tagging t o enhance network secur ity and performance. The switches also support 802.1p priority queues, enabling users to run bandwidth-sensitive applications such as streaming multimedia by prioritizing that traffic in network. These functions allow switches to work seamlessly with VLAN and 802.1p traffic in the network. Aut o Surveillance VLAN will autom atically place the vedio traffic from pre-defined IP surveillance devices to an assigned VLAN with higher priority, so it can be separated from normal data traffic. Asymmetric VLAN is implemented in these switches for a more efficient use of shared resources, such as server or gateway devices.

Network Security. D-Link’s innovative Safeguard Engine function protects the switches against traffic flooding caus ed by virus attacks. Addition al features like 802.1X por t-based authentication provide access control of the networ k with external RADIUS servers. ACL is a po werful tool to screen u nwanted IP or MAC traffic. Storm Control can help to keep the network from being overwhelmed by abnormal traffic. Port Security is another simple but useful authentication method to maintain the network device integrity.

Versatile Management. The new generation of D-Link Smart Managed Switches provides growing businesses simple and easy management of their network. The multi-l ang uag e Web-Based management interface allows administrators to remotely control their network down to the port level. The intuitive easily allows customers to discover multiple D-Link Smart Managed Switches in the same L2 network segment. With this utility, users do not need to change the IP address of PC and provides easy initial setting of smart switches. The switches within the same L2 network segment connected to user’s local PC are displayed on the screen for instant access. It allows extensive switch configuration setting, and basic configuration of discovered devices such as a password change or firmware upgrade.

Users can also access the Switch via Telnet. Basic tasks such as changing the Switch IP address, resetting the settings to factory defaults, setting the administrator password, rebooting the Switch, or upgrading the Switch firmware can be performed using the Command Line Interface (CLI)

In addition, users can utilize the SNMP MIB (Management Information Base) to poll the switches for information about the status, or send out traps of abnorm al events. SNMP supp ort allows users to int egrate

Required Tools and Equipment

• Ground screws (included in the accessory kit): One M4 x 6 mm (metric) pan-head screw.

• Ground cable (not included in the accessory kit): T he grounding cable should be s ized according to

local and national installation requirements. Depending on the power supply and system, a 12 to 6 AWG copper conductor is required for U.S installation. Commercially available 6 AWG wire is recommended. The length of the cable depends on the proximity of the switch to proper grounding facilities.

• A screwdriver (not included in the accessory kit)

The following steps let you connect the switch to a protective ground:

Step 1: Verify if the system power is off. Step 2: Use the ground c able to place t he #8 term inal lug ring on top of the ground-screw opening, as

seen in the figure below. Step 3: Insert the ground screw into the ground-screw opening. Step 4: Using a screwdriver, tighten the ground screw to secure the ground cable to the switch. Step 5: Attach the terminal lug ring at th e other e nd of the gr ound ing cable to a n appr opriate gr ound ing

stud or bolt on rack where the switch is installed. Step 6: Verify if the connections at the ground connector on the switch and the rack are securely

attached.

3 Getting Started

This chapter introduces the management interface of D-Link Smart Managed Switch.

Management Options

The D-Link Smart Managed Switch can be managed through any port on the device by using the Web-based Management.

Each switch must be assigned its own IP Address, which is used for communication with Web-Based Management or a SNMP network manager. The PC should have an IP address in the same range as the switch. Each switch can allow up to four users to access to the Web-Based Management concurrently. Please refer to the following installation instructions for the Web-based Management.

Using Web-based Management

After a successf ul ph ysica l ins ta lla tio n, you can configure the Switch, monitor the network status , an d d is play statistics using a web browser.

Supported Web Browsers

The embedded Web-based Management currently supports the following web browsers: Web Browser via IE8(or later version), Firefox, Chrome and Safari.

Connecting to the Switch

You will need the following equipment to begin the web configuration of your device:

1. A PC with a RJ-45 Ethernet connection

2. A standard Ethernet cable

Connect the Ethernet cable to any of the ports on the front panel of the switch and to the Ethernet port on the PC.

Figure 3.1 – Connected Ethernet cable

Login Web-based Management

In order to login and config ure the s witch vi a an Ether net conn ectio n, the PC must have an IP addres s in t he same subnet as the s witc h. For example, if the switch has an IP address of 10.90.90.90, the PC should have an IP address of 10.x.y.z (where x/y is a num ber betw een 0 ~ 254 and z is a number betwee n 1 ~ 254), and a subnet mask of 255.0.0.0. There are two ways to launch the Web-based Management, you may either click the Web Access button at the top of the SmartConsole Utility or open the web browser and enter 10.90.90.90 (the factory-default IP address) in the address bar.

MDI/MDIX: A medium dependent interface (MDI) port is an Ethernet port connection typicall y used on the Network

Interface Card (NIC) or In tegrated NIC port on a PC. S witches and hubs usually use Medium dependent interface crossover (MDIX) interface. When connecting the Switch to end stations, user have to use straight through Ethernet cables to make sure the Tx/Rx pairs match up properly. When connecting the Switch to other networking devices, a crossover cable must be used.

This switch provides a configurabl e MDI/MDIX function for users. The switches can be se t as an MDI port in order to connect to other hubs or switches without an Ethernet crossover cable.

Auto MDI/MDIX is designed on the switch to detect if the connection is backwards, and automatically chooses MDI or MDIX to properly match the connection. The default setting is “Auto” MDI/MDIX.

When the relay agent receives the DHCP reques t, it adds the opt ion 82 inform ation, and the IP address of the relay agent (if the relay agent is configured), to the packet. Once the option 82 inform ation has been adde d to the packet it is sent on to the DHCP server. When the DHCP server receives the packet, if the server is capable of option 82, i t can im plem ent policies lik e restricting the num ber of IP address es that c an be assigned to a s ingle rem ote ID or circuit ID. Then the DHCP serv er echoes t he option 82 field in the DHCP reply. The D HCP server unicasts reply to the back to the rel ay agent if the request was relayed to the server b y the relay agent. The switch verifies that it originall y inserted the option 82 data. Finally, the rela y agent removes the optio n 82 field and forwar ds the packet to the s witch port that connects to the DHCP client that sent the DHCP request.

L2 Functions > Spanning Tree > STP Bridge Global Settings

The Switch implements three versions of the Spanning Tree Protocol, the Rapid Spanning Tree Protocol (RSTP) as defined b y the IEEE 802.1w specificatio n and a version compatible with the IE EE 802.1D STP and Multiple Spanning T ree Protocol (MSTP) as defined by the IEEE8 02.1 specific ation. RSTP can operate with legacy equipment implementing IEEE 802.1D, however the advantages of using RSTP will be lost.

The IEEE 802.1w Rapid Sp anning T ree Pr otocol ( RSTP) evolved f rom t he 802.1D STP s tandard. R STP was developed in order to ov ercome some lim itations of STP that impede th e function of som e recent switching innovations. The basic function and much of the terminology is the same as STP. Most of the settings configured for STP are als o used for RSTP. T his section introd uces som e new Spannin g Tree c oncepts and illustrates the main differences between the two protocols.

The IEEE 802.1 Multiple Spanning Tree (MSTP) provides various load balancing scenarios by allowing multiple VLANs to be mapped to a single spann ing tree instance, providing m ultiple pathways across the network. For example, while port A is blocked in one STP instance, the same port can be placed in the Forwarding state in another STP instance.

By default, Rapid Spanning Tree is disabled. If enabled, the Switch will listen for BPDU packets and its accompanying Hello pac ket. BPDU packets are sent even if a BPDU pac ket was not received. Therefore, each link between bridges is sensitive to the status of the link. Ultimately this difference results in faster detection of failed links, and thus faster topology adjustment.

By default Multiple Span ning Tree is enabled. It will tag BPDU pack ets to receiving devices an d distinguish spanning tree instances, spanning tree regions and the VLANs associated with them.

After enabling STP, setting the STP Global Setting includes the following options:

Page 60

Figure 4.56 – L2 Functions > Spanning Tree > STP Bridge Global Settings

STP State: Specifies the Spanning Tree Protocol to be Enabled or Disabled. STP Version: You can choose MSTP, RSTP or STP Compatible. The default setting is MSTP. Bridge Priorit y: This valu e betwee n 0 and 61410 s pecif ies the pri ority for f orwardin g pack ets: the lo wer the

value, the higher the priority. The default is 32768. TX Hold Count (1-10): Used to set the maximum number of Hello packets transmitted per interval. The

count can be specified from 1 to 10. The default is 6. Maximum Age (6-40 sec): This value may be set to ensure that old i nf ormation does not endles sl y c irc ulat e

through redundant paths in the network, pr eventing the effec tive propagation of the ne w information. Set b y the Root Bridge, this value will aid in determining that the Switch has spanning tree configuration values consistent with other devices on the bridged LAN. If the value ages out and a BPDU has still not been received from the Root Bridge, the Switch will start sending its own BPDU to all other switches for permission to become the Root Bridge. If it tur ns out that the Switch has the lo west Bridge Ident ifier, it will bec ome the Root Bridge. A time interva l may be chosen between 6 and 4 0 seconds. The default va lue is 20. (Max Age has to have a value bigger than Hello Time)

Hello Time (1-10 se c): The user may set the time interval between transmissions of configuration messages by the root device, thus stating that the Switch is still functioning. The default is 2 seconds.

Forward Delay (4-30 sec): This sets the maximum amount of time that the root device will wait before changing states. The default is 15 seconds.

Root Bridge: Displays the MAC address of the Root Bridge. Root Cost: Displays the cost of the Root Bridge. Root Maximum Age: Displays the Maximum Age of the Root Bridge. Root Forward Delay: Displays the Forward Delay of the Root Bridge. Root port: Displays the root port.

The STP on the switch l evel blocks redundant links between switc hes (and similar network devices). T he port level STP will block redundant links within an STP Group.

It is advisable to define an STP Group to correspond to a VLAN group of ports.

Figure 4.57 – L2 Functions > Spanning Tree > STP Port Settings

From Port/To Port: A consecutive group of ports may be configured starting with the selected port. State: Use the drop-d own menu to enable or disable STP by per-port based. It wil l be selectable after the

global STP is enabled. External Cost: This defines a metric that indicates the relative cost of forwarding pack etsto the specified

port list. Port cost can be set automatically or as a metric value. The default value is 0 (auto).

0 (auto) - Setting 0 f or th e ex ternal c os t will aut omatically set the speed for forwarding packets to the specified port(s) in the list for optimal efficiency. Default por t cost: 100Mbps port = 200000. G igabit port = 20000.

Value 1-200000000 - Define a value bet ween 1 and 200000000 to determine th e external cost. The lower the number, the greater the probability the port will be chosen to forward packets.

Migrate: Setting this parameter as Yes will set the ports to send out BPDU packets to other bridges, requesting inform ation on their STP setting. If the Switch is conf igured for RSTP, the port will be capable to migrate from 802.1 d STP to 802.1w RST P. Migration should be s et as yes on ports c onnected to network stations or segments that are capable of being upgraded to 802.1w RSTP on all or some portion of the segment.

Edge: Selecting the True par ameter designates the port as an edge port. Edge ports cann ot create loops, however an edge port c an lose edge por t status if a topolog y change cr eates a p otential f or a loop. An ed ge port normally should no t receive BPDU packets. If a BPDU pack et is received, it automatically loses edge port status. Selecting th e False parameter indicates that the port does not ha ve edge port status. Se lecting the Auto parameter indicates that the port have edge port status or not have edge port status automatically.

Priority: Specifies th e prior ity of each p ort. Selec table r ange is f rom 0 to 240, and the d efault set ting is 128. The lower the number, the greater the probability the port will be chosen as a root port.

P2P: Choosing the True parameter indicates a point-to-point (P2P) shared link. P2P ports are similar to edge ports, however they are restricted in that a P2P port must operate in full-duplex.

Like edge ports, P2P ports transition to a f orwarding s tate rapidl y thus benef iting from RSTP. A p2p valu e of false indicates that the port cannot have p2p status. Auto allows the port to have p2p status whenever possible and operate as if the p2p status were true. If t he port c a nno t maintain this status, ( f or ex ample if the port is forced to half-duplex operation) the p2p status changes to operate as if the p2p value were False. The default setting for this parameter is Auto.

Restricted Role: Toggle between True and False to s et th e restr icted role s tate o f the pac k et. If s et to True, the port will never be selected to be the Root port. The default value is False.

Notification (TCN) is a BPDU that a bridge sends out to its r oot port to signal a topology cha nge. If set to True, it stops the port from propagating received TCN and to other ports. The default value is False.

Forwarding BPDU: Bridges use Bridge Protocol Data Units (BPDU) to provide spanning tree information. STP BPDUs filtering is useful when a bridge interconnects two regions; each region needing a separate spanning tree. BPDU filtering functions only when STP is disabled either globally or on a single interface. The possible field values are:

Disabled – BPDU filtering is enabled on the port. Enabled – BPDU forwarding is enabled on the port (if STP is disabled).

Hello Time: The interval betwee n two tr ansm iss ions of BPDU p ack ets sent by the Ro ot Br idge to indicate to all other switches that it is indeed the Root Bridge. The default value is 2.

L2 Functions > Multicast > IGMP Snooping

With Internet Group Management Protocol (IGMP) snooping, the Smart Managed Switch can make intelligent multicast forwarding decisions by examining the contents of each frame’s Layer 2 MAC header.

IGMP snooping can help reduce cluttered traffic on the LAN. With IGMP snooping enabled globally, the Smart Managed Switch will forward multicast traffic only to connections that have group members attached.

The default IGMP Snooping version is v3, which works compatible with IGMP versions v1 and v2. The DGS-1210 ser ies support IGMP v1/v2/ v3 awareness. And the IGMP v3 awareness m eans that we do

support IGMP v3 snooping , in other words, switch can read/understand the IG MP control packet which is version3. The Switc h still can bas ed on its rep ort/leave pac ket to do the c orrect beha vior. But f rom the RFC point of view, full IGMP v3 means that it should support sour c e f iltering and it’s n o t pos sibl e to s up port o n the L2 switch.

The settings of IGMP snooping is set by each VLAN individually.

Figure 4.63 – L2 Functions > Multicast > IGMP Snoop ing

By default, IGMP is disabled. If enabled, the IGMP Global Settings will need to be entered: Host Timeout (130-153025 sec): This is the interval after which a learned host port entry will be purged. For

each host port learned, a 'Por t Purge Timer' runs for 'Host Port Purge Interval'. This timer will be restarted whenever a report m ess age f r om hos t is r ec eived ove r that port. If no report messages are rec ei ve d f or ' Hos t Port Purge Interval' tim e, the learned h ost entr y will be purged f rom the multicast gr oup. The default value is 260 seconds.

Robustness Variable (2-255 sec): The Robustness Variable allows adjustment for the expected packet loss on a s ubnet. If a subne t is expected to be lossy, the Robustness Variable m ay need to be incr eased. The Robustness Variable cannot be set to zero, and it SHOULD NOT be. Default is 2 seconds.

Query Interval (60-600 se c): The Query Interval is the inter val bet ween Ge neral Queri es sen t. B y adjusting the Query Interval, the number of IGMP m essages can be increased or decreased; larger v alues will caus e IGMP Queries to be sent less often. Default value is 125 seconds.

Router Timeout (60-600 sec): This is the inter val after which a learned ro uter port entry will be purg ed. For each router port learn ed, a 'Rout er Port Purge Tim er' runs for 'Router Port Purge Inter val'. This timer will be restarted whenever a Query control message is received over that port. If there are no Query control

Last Member Query Interval (1-25 sec): The Last Member Query Interval is the Max Response Time inserted into Group-Spec ific Queries sent in response to Leave Group messages, and is also the am ount of time between Group-Spec ific Query mes sages. This value m ay be adjusted to modif y the "leave latenc y" of the network. A reduced value results in reduced time to detect the loss of the last member of a group. Default is 1 second.

Max Response Time (10-25 sec): T he Max Response Time specifies the maxim um allowed time bef ore sending a responding report m ess age. Adjusting this setting ef fects the "leave latenc y", or the time b etween the moment the last host leav es a group and when the multic ast server is notified that there are no more members. It also a llows adjustm ents for c ontrolling the frequency of IGMP traff ic on a subnet. Default is 1 0 seconds.

L2 Functions > Multicast > MLD Snooping

Multicast Listener Disco very (MLD) Snoop ing is an IPv6 functio n used similarl y to IGMP snooping in I Pv4. It is used to discover por ts on a VLAN that are requesting multic ast data. Instead of flooding all ports on a selected VLAN with multicast traffic, MLD snooping will only forward multicast data to ports that wish to receive this data through the use of quer ies and reports produced by the reques ting ports an d the source of the multicast traffic.

MLD snooping is accomplished through the examination of the layer 3 part of an MLD control packet transferred between en d nodes and a MLD router. When the Switc h discovers that this route is reques ting multicast traff ic, it adds the port directly attach ed to it into the correct IPv6 m ulticast table, and begins the process of forwarding m ulticast traffic to that port . This entry in the multic ast routing table records th e port, the VLAN ID, and the assoc iated multicast IPv6 m ulticast group addres s, and then considers this port to be an active listening port. The active listening ports are the only ones to receive multicast group data.

Figure 4.66 – L2 Functions > Multicast > MLD Snooping

MLD Global Settings: MLD Snooping: Enable or disable the MLD Snooping. Host Timeout (130-153025 sec): Specif ies th e time interval in seconds after whi c h a port is removed from a

Multicast Group. Ports ar e removed if a Multicast group MLD r eport was not received from a Multicast port within the defined Host Timeout period. The possible field range is 130 - 153025 seconds. The default timeout is 260 seconds.

Router Timeout (60-600): Specifies the time interval in seconds the Multicast router waits to receive a message before it times out. The possible field range is 60 - 600 seconds. The default timeout is 125 seconds.

Robustness Variable (2-255): The Robustness Variable allows adjustment for the expected packet loss on a subnet. If a subnet is expected to be lossy, the Robustness Variable may be increased. The Robustness Variable cannot be set to zero, and SHOULD NOT be one. Default is 2 seconds. Last Member Query Interval (1-25 sec): The Last Member Query Interval is the Max Response Time inserted into GroupSpecific Queries sent in response to Leave Group messages, and is also the amount of time between Group-Specific Query messages. This value may be adjusted to modify the "leave latency" of network. A

reduced value results in reduced time to detect the loss of the last member of a group. The default value is 1 second. Query Interval (60-600 sec): The Query Interval is the interval between General Queries sent. By adjusting the Query Interval, the number of MLD messages can increase or decrease; larger values cause MLD Queries to be sent less often. Default is 125 seconds.

Max Response Time ( 10-25 sec): Spec ifies the tim e inter val in seconds af ter which a por t is rem oved from the Multicast mem bership group.

L3 Functions > IPv4 Static Route

The Switch supports static routing for IPv4 formatted addressing. User can create up to 256 static route entries for IPv4. For IPv4 static routes, once a static route has been set, the Switch will send an ARP request packet to the next hop rout er that has been set by the user . Once an ARP response has bee n retrieved by the Switch from that next hop, the r o ute bec omes enabled. However, if the ARP entry already exists, an ARP request will not be sent.

The Switch also support s a floating static route, which means that the user m ay create an alternat ive static route to a dif f erent nex t ho p. T his sec o ndary next hop dev ice r o ute is c ons id ered as a backup static r o ute for when the primar y static route is down. If the primary route is lost, the back up route will uplink and its status will become active. E ntries into the Switch’s f orwarding table can be made us ing both an IP address s ubnet mask and a gateway.

Security > ARP Spoofing Pre vention

ARP spoofing, also known as ARP poisoning, is a method to attack an Ethernet network by allowing an attacker to sniff data frames on a LAN, modif ying the traffic, or stopping the traffic (known as a D enial of Service – DoS attack ). The main idea of ARP spoofing is to send fake or spoofed ARP messages to an Ethernet network. It assoc iates the attacker's or random MAC address with the IP address of another no de such as the default gateway. Any traffic m eant for that IP address would be mistakenly re-direc ted to the node specified by the attacker.

A common DoS att ack today can be done b y associating a n onexistent or s pecified MAC address to th e IP address of the network’s default gateway. The malicious attacker only needs to broadcast one gratuitous ARP to the network c laiming to be the gateway, so that the whole net work operation is turned down as a ll packets to the Internet will be directed to the wrong node.

The ARP Spoofing Prevent ion func tion can discard the ARP Spoof ing Attac k in the network by chec king th e gratuitous ARP packets and filtering those with illegal IP or MAC addresses.

Security > Smart Binding > Smart Binding Settings

The primary purpose of Smart Binding is to restr ict client access to a switch by enabling administrators t o configure pairs of client MAC and IP addresses that are allowed to access networks through a switch.

The Sm art Binding function is port-base d, meaning that a user can enable or disable th e function on any individual port. Onc e Sm art B indin g is enabled on a s witch por t, the s witch will rest rict or al low client acces s by checking the pair of IP-MAC addresses with the pre-configured database, also k nown as th e “IM PB w hite list”.

Users can enable or disable the Inspection packets and DHCP Snooping on the Switch.

Figure 4.113 – Security > Smart Binding > Smart Binding Settings

The Smart Binding Settings page contains the following fields:

From Port/ To Port: Select a range of ports to set for IP-MAC-port binding. State: Use the drop-down menu to enable or disable these ports for Smart Binding.

Enabled –Enable Smart Binding with related configurations to the ports

Disabled –Disable Smart Binding. Packet Inspection: Specifies ARP Inspection or IP+ARP Inspection for the IP pack ets. If ARP inspection is

selected, the Switch will in spect incoming ARP pack ets and compare them with t he Switch’s Smart Binding white list entries. If the IP-MAC pair of an ARP packet is not found in the white l ist, the S witch will bloc k the MAC address. A m ajor benefit of Loos e state is that it uses less CPU r esources. However, it cannot block malicious users w ho send only un icast IP packets . An example of th is is that a m alicious user can per form DoS attacks b y statically configuri ng the ARP tabl e on their PC. I n this case, th e Switch cannot b lock such attacks because the PC will not send out AR P packets. If ARP+ IP Inspection mode is selec ted, th e S witch will inspect all incom ing ARP and IP packets and compare them to the IMP B white list. If the IP-MAC pair find a match in the white lis t, the pack ets f rom that MA C address are un block ed. If not, the MAC addres s will stay blocked. While the mode examines every ingress ARP and IP packet, it enforces better security.

DHCP Snooping: By enable DHCP Snooping, the switch will snoop the packets sent from DHCP Server and clients, and update information to the White List. This includes DHCPv6 snooping.

IEEE-802.1X provid es a se curity standard f or networ k access c ontrol, especially in Wi-Fi wireles s networks.

802.1X holds a network port disconnected until authentication is completed. The switch uses Extensible Authentication Protoco l over LANs (EAPOL) to exchange authent ication protocol c lient identity (such as a user name) with the c lient, and forward it to another r emote RADIUS aut hentication server to verify access rights. The E AP packet from the RADIUS s erver also contains the aut hentication method to be used. The client can reject the authentic ation m ethod and req uest ano ther, dep ending o n the conf iguration of the cli ent software and the RADIUS server. Depending on the authenticated results, the port is either made av ailable to the user, or the user is denied access to the network.

Figure 4.118 – AAA > 802.1x Global Settings

Authentication State: Specifies to enable or disable the 802.1X function. Forward EAPOL PDU: This is a global setting to control the forwarding of EAPOL PDU. When 802.1X

functionality is dis abled glo ball y or f or a port, and if 80 2.1X f orward PDU is e nabl ed both glo ba ll y and for the port, a received EAPOL pa ck et on the port will be floo ded in the s am e VLAN to t hose ports for which 802.1 X forward PDU is enabled and 802.1X is disabled (globally or just for the port). The default state is disabled.

Authentication Protocol: Indica tes the 802.1X Prot ocol on the device. The p ossible field values are Local and RADIUS.

From Port/To Port: Enter the port or ports to be set. QuietPeriod (0 – 65535 sec): Sets the number of seconds that the switch remains in the quiet state

following a failed authentication exchange with the client. Default is 60 seconds. ServerTimeout (1 – 65535 s ec): Sets the amount of time the switch waits for a response from the client

before resending the response to the authentication server. Default is 30 seconds.

TxPeriod (1 – 65535 sec): This sets the TxPeriod of time for the authenticator PA E state machine. This

value determines the period of an EAP Request/Identity packet transmitted to the client. Default is 30 seconds.

ReAuthentication: Determines whether regular reauthentication will take place on this port. The default setting is Disabled.

Capability: Indicates the capability of the 802.1X. The possible field values are: Authenticator – Specifies the Authenticator settings to be applied on a per-port bas is. None – Disable 802.1X functions on the port. SuppTimeout (1 – 65535 sec): This value determ ines timeout conditions in the exchanges between the

Authenticator and the client. Default is 30 seconds. MaxReq (1 – 10): This param eter specifies the maxim um number of times that the switch retransmits an

EAP request (md-5challnege) to the client before it times out the authentication session. Default is 2 times. ReAuthPeriod (1 – 65535 sec): A constant that defines a nonzero number of seconds between periodic

reauthentication of the client. The default setting is 3600 seconds. Port Control: This allows user to control the port authorization state.

Select ForceAuthorized to disable 80 2.1X and cause the port to transition to the authorized state

without an y authentication exchange require d. This means the port transm its and receives normal

traffic without 802.1X-based authentication of the client.

If ForceUnauthorized is selected, the port will remain in the unauthorized state, ignoring all

attempts by the client to a ut henticate. The Switch cannot pro vid e aut he ntic at io n se r vices to th e c lient

through the interface.

If Auto is selected, it will enable 802.1X and cause the port to begin in the unauthorized state,

allowing only EAPOL f rames to be sent and recei ved through the port. The au thentication process

begins when the link state of the port transit ions from down to up, or when an E APOL-start f rame is

received. The Switch then requests the identity of the client and begins relaying authentication

messages between the client and the authentication server.

The default setting is Auto.

Direction: Sets the administrative-controlled direction on the port. The possible field values are:

Both – Specifies the control is exerted over both incoming and outgoing traffic through the controlled

port selected in the first field. In – Disables the support in the present firmware release.
