IP Source Guard (IPSG) IP source guard (IP SG) is a security featur e that filters IP pack ets based on the source ID. The source ID may either be source IP addr ess or a source IP address source MAC a ddress pair. IPSG is disabled b y default. DHCP Snooping DHCP Snooping is a security feature that monito rs DHCP messa ges betw een a DH CP client and DHCP server. It filters harmful DHCP messages a nd builds a bindings datab ase of (MAC addr ess, IP addr ess, VLAN ID, port) tuples th at are spe cified as author ized. DHCP snooping can be enabled globally and on specifi c VLANs. P orts wi thin the VLAN can be configured to be tr usted or untru sted. DHCP s ervers must be reached through trusted ports. DHCP L2 Relay This featur e permits L3 Rela y agent functionality in L2 switched networks. Dynamic ARP Inspection Dynamic ARP Insp ection (D AI) is a security feature that r ejects invalid and mal icious ARP packets. The featur e prevents a class of man-in-t he-middle attacks, whe re an unfriendly station intercepts traffic for other stations by poisoning the ARP caches of it s unsuspecting neighbors. The miscr eant sends AR P r equests or r esponses mapping anot her station's IP addr e ss to it s own MAC addr ess. Dynamic ARP Inspection relies on DHCP Snooping. MLD Sn ooping In IPv4, Layer 2 switches can use IGMP Snooping to li mit the f looding o f multicas t traffi c by dynamically config uring Layer 2 i nterfaces so that multicast traffic i s forwar ded to only those i nterfaces asso ciat ed wit h IP mu lti cast add ress. In IPv6, MLD snooping perform s a similar function. W ith MLD sn ooping, I Pv6 multic ast data is select ively f orwar ded to a list of p orts inten ded to r eceive the dat a (instead o f being flooded to all of the ports in a V LAN). This list is const ructe d by snooping IPv6 multicast control packets. Multic ast I P traffic is traffic that is destined to a host group. Host groups are iden tified by class D IP addresses, which range from 224. 0.0.

0 to 239.2 55.255.255. Bas ed on the IGMP query and r eport messages, the swit ch forwards traffic only to the ports that r equest the multica st traffi c. This prevents the switc h from bro adcasti ng the tra ffic to all por ts and poss ibly aff ecting network performance. Port Mirroring P ort mirroring monitors and mirrors network traffic by forwar ding copies of incoming and outg oing packets from up to four source ports to a monitoring port. Broad cast St orm Co ntrol When Layer 2 frames ar e forwarded, br oadcast, unknown unicast, and multicast frames ar e flooded to all ports on the r elevant vi rtual local ar ea network (V LAN). The flooding occupies bandwidth, and loads all nodes connected on all ports. Storm control limits the amount of broadcast, unknow n unicast, and multicast f rames accepted and forwar ded by the s witch. Media -Depende nt Interfa ce (MDI ) is the s tandard wiri ng for end sta tions, and the standard wiring for hubs and switches is known as Media-Dependent Interface with Crossover (MDIX). Auto Negotiation A uto nego tiation allows t he switch to adver tise mo des of operation. The auto negotiation function provides the means to ex change informati on between two switches that share a p oint-to-poi nt link segment, and to auto maticall y configure both s witches to ta ke maximum ad vantage of their tr ansmissi on capabilities. The P owe rConnect 6200 Series enhances auto nego tiation by providing port advertisement. P ort advertisement a llows the system administrato r to configure the port speeds a dvertised. T ransmi ssions are temporarily halted to prevent buffer overflows. HOL blocking queues packets, and the packets at the head of the queue are forwarded before pack ets at the end of the queue. Back Pressure Support On half -duplex links, a re ceiver may prevent b uffer overflows by occupying the link so that it is unavailable for additional traffic.

When ASF is enabled, the memory management unit (MMU) can forwar d a packet to the egr e ss port before it has been entirely re ceived on t he Cell Buffer P ool (CBP) memory. AFS, which is also known as cut-through mode, is configurable through the command-line interface. P acket s are cla ssified as belonging to a VLAN based on either th e VLAN tag or a combinati on of the ingress port and packet contents. P ackets sharing common attributes can be groups in the same VLAN. When a port uses 802.1X p ort authe nticati on, packets can be a ssign ed to a VLAN based on the result of the 802.1X authentication a client uses when it accesses the switch. This feature is useful for as signi ng traffic to Guest VLANs or V oice V LANs. P rotocol -based VLANs ar e used for isolating Layer 2 traffic for differing Layer 3 protocols.It is an extension of t he common VLAN. T raffic from protected ports is sent only to the uplink ports and cannot be sent to other ports within the VLAN. Subn et-bas ed VLAN This featur e allows incoming untagged pack ets to b e assigned to a V LAN and traffic class ba sed on the source IP address of the packet. The additiona l tag helps differentiate between customers in th e Metropolitan Area Networks (MA N) while preserving indi vidual customer ’s VLAN identification when th ey enter their own 802.1Q dom ain. Prot ocol- based VLAN s In a protocol-based VLAN, traffic is bridged through specified ports based on the VLAN’s protocol. User- defined pack et filters dete rmine if a particular packet be longs to a particular VLAN. P rotocol-based VLANs ar e most often used in situations where network segments contain hosts running multiple protocols. Th e port is m arked as being in loop-in consistent state. In this state, the p ort does not forward packets. P acket s as signe d to various VLANs ar e transmitte d along differ ent paths w ithin MSTP Re gions (MST Reg ions). Regions are one or more interconnected MSTP bridges with id entical MSTP settings.

The MSTP standard lets adminis trators a ssign VLAN traffic to uni que paths.The priorit y of a Bridge ID can be se t to zero but another Bridge ID with a lower mac addr ess could also s et its priori ty to zero and tak e over root. Bridge Protoc ol Data Unit Guar d Spanning T ree BPDU Guar d is used to disable the port in case a new device tries to enter the already e xisting topology of STP. Thus devices, which wer e originally not a p art of STP, ar e not allowed to influence the STP topology. Link Ag gregation Features Link A ggreg ation Up to eight ports can combine to form a single Link Aggregat ed Group (LAG). This enables fault tolerance protection from phy sical link disrup tion, higher bandwidth connections and improved bandwidth granularity. A LAG is composed of ports of the same speed, set to full-duplex op eration. Link L ayer Dis cove ry Prot ocol ( LLDP ) for Medi a Endp oin t Devic es The Link Layer Discovery Protocol for Media Endpoi nt Devices (LLDP -MED) provides an extension to the LLDP standard for network configuration and policy, device location, P ower over Ethernet management, and inventory management.The priority level en ables the separa tion of vo ice and da ta traff ic coming onto the po rt.Y ou can also configur e the software to allo w traffic on a VLAN to be tr eated a s if the VL AN wer e a route r port. OSPF Configuration The Maximum P aths field allows OSPF to r eport a maximum of 4 paths for a given dest ination.IP Helper P rovides the ability to relay various protocols to servers on a different subnet. The ex ception to this is, if that VRRP group is t he IP addr ess owner, its priority is fixed at 255 and can not be reduced through tracking process. MAC Address Suppor ted Features MAC Ad dress Su pport The switch supp orts up to 32K Media Access Control (MA C) address es and reserve s two MAC addr esses for sy ste m us e.

Self -Learnin g MAC Address es The switch enables MA C addresses to be automatically learned from incoming pack ets. Automatic Aging for MAC Addresses MAC addr esses that have no t seen any traffic for a given period a re aged out, which prevents the b ridging table from o verflowing. F uture pack ets addr essed to or from this address are more eff iciently forwarded. In Layer 2 multicast services, a single frame addressed to a specific multicast address is received, and copies of the frame to b e transmitted on each relevant port are cr eated. Addition ally, the admini strator ca n statical ly add entries i n to the ARP ta ble. Open Sh ortest Path Fi rst The Open Shortest P at h F i rst (OSPF) Ro uting protocol defines two area types: regular OSPF area and OSPF stub ar ea. OSPF internal and e xternal rout e information may be propagated throughout the r egular OSPF ar e a; it is capable of supp orting transit t raffic and virtual li nks. D HC P i s a n ex te ns i on to B o o tP a l lo wi n g ad d i t io n a l s et u p p a ra m e te rs t o b e rec e i v ed f r o m a network s erver upon system st artup. Routi ng Inform ation Prot ocol The routing protocol used within an autonomous Internet sys tem is referr ed to as an i nterior gateway protocol (IGP). RIP is an I GP that is designed to work with moderate-size networks. Virtual Routin g Redu ndan cy Pro toco l Virtual Rout ing Redundancy P rotocol (VRRP) is used to provide hosts with redundant routers in the network t opology w ithout any need for the hosts to reconfigure or know that the re ar e mu ltiple rout ers. IPv6 Ro uting Fe atures IPv6 6 to 4 Auto T unnels Automatica lly formed IPv4 6 to 4 tunnels for carry ing IPv6 traffic. The automatic tunnel IPv4 destination addr ess i s derived from the 6 to 4 IPv6 address of the tunnel nexthop. There is support the functional ity of a 6 t o 4 border rout er that con nects a 6 to 4 site to a 6 to 4 doma in.

OSPFv3 is a new routing component based on the OSPF version 2 component. In dual s tack IPv6, y ou can configure and us e both OSPF and OSPFv3 components. IPv6 Routes Since IPv4 and IPv 6 can coexist on a netwo rk, the rout e r on such a network needs to forward both traffic types. Given this coexi stence, the P owerConnect 6200 Series mainta ins two routing tables, rto and rto6, which ar e both capabl e of forwar ding over the same s et of interfaces. IPv 6 interfaces ar e managed in a manner similar to I Pv4 interfaces.A prim ary benef it of usi ng V oice VLAN is t o ensure th at the sound quality of a n IP phone is safeg uarded from det eriorating when the data traffic on the port i s high. The system uses the source MAC address of the traffic traveling through the por t to identify the IP phone data flow. Auto V oIP P rovides ea se of use for the user in setting up V oI P for IP phone s on a switch. This is a ccomplished by enabling a V oIP profile that a user can select on a per port ba sis. Class of Service Rate Limiting The Class of Service interface confi g uration feature has been enhanced to allow outb ound rate limi ting on specified p orts. Differentiated Services IPv6 Support Extends the existing QoS A CL and DiffServ functionality by providing support for IPv6 packet classification. Ethernet I Pv6 packets are distinguished from IPv4 packets by a unique Etherty pe value (all IPv6 classifiers include the Ethertype field). Quality of Service (QoS) Support T o overcome unpredict able network traffic and optimi ze performance, you can apply Quality of Service (QoS) th roughout the network. Q oS ensures that the networ k traffi c is prior itized according to a specifi c criteria. This provides the desired QoS behavior for d ifferent types of network traffic when t he complexities of DiffServ a re not r equ ired. This multica st route table is then use d to route the multicas t packets.

Inter net Group Manage ment Pr otocol The Internet Group Management Protocol (I GMP ) is used by IPv4 systems (hosts and routers) to r eport their IP mult icast group members hips to any neig hboring multicast routers. Protocol Independent Multicast-Dense Mode P rotoco l Independent Multicast (PIM) is a standard multicast routing protocol that p rovides scalable inter-domain mult ica st rou ting acro ss th e Inte rnet, ind epend ent of the mech anism s prov ided by any particular unicast routing proto col. PIM- DM cr eates source-bas ed shortest-p ath distribution t rees, making use of r everse pa th forwarding (RPF). Protocol Independent Multicast-Sparse Mode P rotocol Independent Multica st-Sparse Mode (PIM-S M) is used to eff icientl y route multica st traf fic to multicast g roups that may span wi de area ne tworks, and where bandwidth is a constraint. PIM-SM uses shared trees by defaul t and im plemen ts source -base d tr ees for effi ci enc y. Th is data thre sho ld ra te is u sed to toggle betw een trees. IPv6 Mul ticast Fea tures Protocol Independent Multicast IPv6 Su pport PIM-DM and PIM-SM suppor t IPv6 routes. MLD protocol enables the IPv 6 router to discover the p resence of multicast listeners, the nodes that want to receive the multicast data pa ckets, on its dire ctly atta ched interfaces. The prot ocol specifically disco ver s whi ch mu ltic ast ad dresse s are of inte rest to its neighboring nodes and provid es this information to th e multic ast rout ing prot ocol t hat mak e the d ecisio n on the flow of the mult icast d ata pac kets.

A CLs are used to pro vide traffic flow control, r estrict contents of routing updates, decide which types of traffic ar e forwarded or block ed, and above all provide security for the network. Only authenticated and approv ed system users can transmit an d r eceive da ta. Supplicants are authenticated through the Re mote Authenti cation Dia l In User Se rvice (RADIUS) serv er using the Extensi ble Authent ication Protocol ( EAP). Also supported ar e PEAP, EAP - TTL, EAP - TTLS, and EAP - TLS. MAC- based authent icatio n allows mul tiple sup plicants connected to th e same p ort to each authentic ate individually. F or example, a system attached to the p ort might be requir ed to authent icate in order to gain acc ess to the networ k, while a V oIP phone mig ht not need to a uthentic ate in order to send voi ce traffic through the port. These addresses are manually defined or learned on that port. When a frame is seen on a locked port, and the frame source MA C addr ess is no t tied to that port, the protect ion mecha nism is inv oked. P asswor ds for SSH, T elnet, HTTP, HTTPS, and SNMP access are assigned security features.Secure Sockets Layer (SSL) protocol provides a means of abstracting an encrypted connection between two stations. Once established, such a connection is virtually no differ ent to use than an unsecured connection. It describes the adva ntages of specifi c functions that the P owerConnect 6200 Series prov ide s and inc lud es in fo rmat io n abo ut conf ig uring those functions using the command line interface (CLI).
