The S3600-SI series provide:

 Basic routing functions and service features.  Basic Intelligent Resilient Framework (IRF) where devices are connected through

fabric ports for centralized management.

 Support the feature includes DDM (Distributed Device Management).

The S3600-EI series provide:

 Complex routing protocols and abundant service features.  The Enhanced Intelligent Resilient Framework (IRF) feature, where the

IRF-supported switches tha t are of the same type (called u nits) ar e conn ected to form a “device un ion” or a fabric . Trough a fabric, you can (1) manage m ultiple devices but with one connection and one IP address, thus decreasing the overheads; (2) expand the net work by adding devices as des ired, thus protecting the existing investm ent; and (3) have high reliability of N + 1 redundancy, thus avoiding single point failures which can result in service interruption.

 Support DDM (Distributed Device Management)  Support DDR (Distributed Resilient Routing)  Support DLA(Distributed Link Aggregation) through LACP and across devices

Chapter 3 Software Features

3.1 Basic Features

3.1.1 Link Aggregation

The link aggregation function is used for the connection between Ethernet switches or between the switches and high-speed servers. It is a simple and cheap way to expand the bandwidth of a s witch port and balance the traff ic among all the ports in a link aggregation. Moreover, it enhances the connection reliability.

With link aggregation, several Ethernet ports on a switch are bundled together and are considered one logic al port inside the switch. The switch autom atically balances the traffic among the ports and increases the bandwidth in this aggregation, while ensuring the right order of packets for the sake of service compatibility. If the link on a port in the aggregation fails, the traff ic on it is distributed among other ports wit hout interrupting the normal service. After the port recovers, the traffic is automatically distri bute d aga in so that the port can sh are the load together with ot hers. The S3600 series support manual link aggregat ion and dynamic link aggreg ation through the link aggregatio n control protocol (LACP).

IEEE802.3ad-based LACP dynamically aggregates and de-aggregates links. A LACP-enabled port not ifies the remote end of infor mation on system priorit y, s ystem MAC, port priorit y, port number and operation k ey by sending link aggregation co ntrol protocol data units (LACPDUs). The r emote end receives the inform ation, and then compares it with that of oth er por ts f or deter mining the ports to be aggregat e d, so that an agreement can be achieved on port aggregation or leaving a dynamic aggregation.

3.1.2 Broadcast Suppression

The broadcast suppression function is used to suppress the propagation of large amount of unknown unicas t, multicas t or broadcast packets in a network , thus limiti ng their impact on the operating efficiency of the network.

For the S3600 series, broadcast suppression is configured on port. After configuring a broadcast suppression ratio on a port, you can monitor the broadcast traffic of unknown unicast, multicast an d bro adcast packets on it. W hen the t raff ic ex ceeds the s p ec ified bandwidth limit, the s witc h drops th e ex c ess i ve traffic and r educ es the traffic ratio to a rational amount to guarant ee the normal operation of network ser vices. The S3600

Page 61

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-2

series can implement broadcast suppression not only based on port rate ratio but also on pps.

For the S3600 series, the broadcast suppression function not only can be enabled/disabled globally in the whole fabric, but also can be enabled/disabled on individual ports. When the global broadcast suppression ratio is set, the broadcast suppression ratio on each port is set to the value equal to the global broadcast suppression ratio.

3.1.3 VLAN

Virtual l ocal area net work (VLAN) is a tech nology that im plements virtual workgroups by assigning devices of the same category (such as PC) on a LAN into network segments logically rather than physically. IEEE 802.1Q is the standard protocol for the VLAN technology.

As devices are divided logically rather than physically , they do not necessarily reside on the same physical network segment. After the division, the broadcast and unicast traffic is confined inside the VLAN to which it belongs.

The VLAN technolog y helps network f low contr ol, n etwork m anagem ent, and net work security.

3.1.4 STP/RSTP/MSTP

The spanning tree prot ocol ( ST P) /Rapid spanni ng tr ee pr otoc ol ( R STP) prunes a l oop L2 switching network into a loop-free tree (all d ata on the L2 switchin g network m ust travel along the spanning tree), thereby avoiding network broadcast storms caused by network loops and providing redundant links for data forwarding.

Basically, STP/RSTP is to generate a “tree” whose ro ot is a s witch c alled root bridge. Which switch is to be se lected as the root bri dge is based on their sett ings (such as switch priority and MAC address), but there should be only one root bridge at any time. Setting out from the root, a tree stretches through the switches. A non-root switch forwards data to the root from its root port and to the connected network segment from its designated port. A root periodically transmits configuration BPDUs, while a non-root switch receives and forwards them. If a switch receives configuration BPDUs from two or more ports, it assumes that there is a loop in the network. To eliminate the loop, the switch selects one of the ports as the root port and blocks others. When a port receives no configuration BPDU s f or a long tim e, the s witch considers that the conf igurati on of this port has timed out and the network topology may have changed. Then it recalculates the network topology and generates a new tree.

RSTP is an STP enhancement that significantly shortens the time for the network topology to stabilize.

Page 62

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-3

RSTP is a single spanning tree prot ocol, that is, only one tree is generat ed within a switching network. To ensure the interior communications of VLANs, each VLAN of a network must be cons ecutively distributed along the spanning tre e; otherwise, so me VLANs are parted because of the blocking of interior link, and the inside VLAN communications fail. In the event of special requirements or failure to distribute VLANs along the path of the spanning tree, you can configure the STP-ignore attribute of VLAN on the specific switch to solve this problem.

If a VLAN is specified as the VLAN of STP-Ignored, packets of this VLAN are in forwarding mode at all p orts on the switch, receiving no limitation from the spanning tree path which is calculated by the protocol.

MSTP stands for Multiple Spanning Tree Protocol, which is com patible with STP and RSTP.

STP cannot transit fas t. Even on a point-to-point l ink or edge port, it has to take an interval as long as twice f orward delay before the port can transit to the forwar ding state.

RSTP can converge fast. But it still has the following drawback like STP: There is only one spanning tree in the LAN. All the bridges in the LAN share the same spanning tree, and the packets of all VLANs are f orwarded along the sam e tree. Therefore it is not possible to block redundant links by VLANs.

MSTP makes up for the dra wback of STP and RST P. It m akes the network c onverge fast and the traffic of different VLANs flows along their respective paths, which provides a better load-balance mechanism on redundant links.

The S3600 series support standard MSTP, that is, the S3600 series support standard

802.1s packets.

3.2 Network Protocol Fe atures

3.2.1 DHCP Client

On a contemporary large-sized and complex network, some computers are mobile and the available IP addresses are far from adequate comparing with the fast-growing number of computers . To addres s the issue, the d ynamic host conf iguration protocol (DHCP) was introduced. DHCP works in the client/server model, where the DHCP client requests the DHCP server for configuration information dynamicall y, and upon the receipt of the request the DHCP server returns the configuration inf ormation (IP address for example) based on the adopted policy.

Page 63

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-4

3.2.2 DHCP Relay

An Ethernet switch with DHCP Relay enabled relays the messages between a DHCP server and a client. It can have a DHCP server in a subnet serves another subnet that has no DHCP server. With DHCP Relay, a network administrator needs not to deploy a DHCP server for every subnet, thereby reducing the investment cost. The DHCP security function checks the validity of user addresses under VLAN interfaces.

3.2.3 UDP Helper

UDP Helper mainly functions to relay and forward the specified UDP broadcast packets. It can transform UD P broadcast packets into unicast packets and send them to the specified servers.

When a UDP Helper enabled port rece ives a UDP pa c k e t , the swit ch m akes the rela y and forwarding decision based on the UDP port number in the packet. If the packet is to be relayed and forwarded, the switch changes the destinatio n IP addr ess in the IP header and sends the pack et to its destination server; if not, the switch sends the packet to the upper layer modules. For the relay of BOOTP/DHCP broadcast packets, the system sends the response to a request by unicas t rather than broadcast unless required by the client.

3.2.4 DNS Client

The IP-to-domain-name resolution function is added to the new DNS Client that is based on the old DN S Client. As a resu lt, the n ew DN S client implem ents the pointer query function in the DNS system and provides IP-to-domain-name resolution for other communication modules that need the resolution. The DN S Client conforms to RFC 1034 and RFC 1035.

3.2.5 DHCP Server

The built-in DHCP Server function in a Layer 3 switch can directly allocate addresses to locally attached users and manage the allocated ad dresses. By using this fun ction, carriers can save the investment in external DHCP servers.

Only the S3600-EI series support the function.

3.2.6 DHCP Snooping

DHCP snooping monitors DHCP packets at Layer 2 on a DHCP client. DHCP snoopi ng captures and analyses DH CP pac kets to obtain user inform ation such as the MAC addresses of users, the IP addresses assigned to users, and the types of the information assigned to users, so as to maintain user information entries on the DHCP

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-5

client. Such information can be notified to 802.1x. In addition, you can query and analyze such information.

The DHCP snooping trust function is based on DHCP snooping. By configuring ports to be trusted or untrusted, you can use this function to control the sources of DHCP Server packets, so as to prevent private or bogus DHCP servers from passing their information through the switch.

3.3 Routing Features

 Note:

When a switch runs a routing protocol, it can perform router functions. In this chapter, a router represents a generic router or a L3 routing switch that runs routing protocols.

3.3.1 Static Routing and Default Routing

I. Static Routing

A static route is a route that is m anuall y configured by a network adm inistrator. For a routing switch on a simple network, static routes are adequate for the switch to operate normally.

The proper configuratio n and use of static routes can effectively guaran tee network security and guarantee bandwidth resources to crucial applications as well. However, if the network topology changes, as the result of a network device failure for example, the static routes cannot change autom aticall y to accommodate to th e change with out the help of an administrator.

II. Default routing

A default route is used only when no route match is found. In default routing, the mask and destination addresses are both 0.0.0.0 in the routing table. When there are a large number of users in communications, default routing is useful because it uses less time and fewer bandwidth resou rces to route and forward pack ets in comparison to other routing methods.

Page 65

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-6

3.3.2 RIP

Routing information protocol (RIP) is a widely used interior gateway protocol (IGP) and is D-V Distance-Vector (D-V) algorithm-based. It is suitable for small-sized and sim ple networks.

RIP switches routing inform ation with User Datagram Protocol (UDP) datagr ams and sends updates regularl y. It us es hop count as the routing m etric and allows up to 15 hops. RIP has two versions: RIPv1 and RIPv2. RIPv2 supports plain text authentication and MD5 authentication an d variable-lengt h subnet mask s as well. Both of them can work with the S3600 series.

3.3.3 OSPF

Open shortest path f irst (OSPF) is an IGP protocol based on link-state (L-S), which is suitable for large-sized and com plex net works.

A router uses OSPF to maintain the routing table information in an autonomous system (AS). In an AS, ever y OSPF router collects and broa dcasts its link state information throughout the AS with the f looding algorithm to synchronize the li nk state databases (LSDBs) of other OS PF routers. W ith its LSDB, the router calc ulates a shortest -path tree with itself as the root and other network nodes as leaves, thus getting its optim al reachable routes inside the system.

3.4 Multicast Features

 Note:

When a switch runs a routing protocol, it can perform router functions. In this chapter, a router represents a generic router or a L3 routing switch that runs routing protocols.

3.4.1 IGMP Snooping

Internet group management protocol snooping (IGMP snooping) is a multicast monitoring mechanism that runs on L2 Ethernet switches to manage and control multicast groups.

The IGMP snooping runs at the link layer. When a L2 Ethernet switch receives an IGMP message that is sent from a host to a router, it uses the IGMP snooping to analyze the information carried by the IGMP message. When the switch hears an IGMP Host Report message from the host, it adds the host to the appropriate multicast table. When

Page 66

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-7

hearing an IGMP Leave m essage, it removes the host from the multicast table. By continuously listening to IGMP packets, the switch cr eates and maintains a L 2 MAC multicast address table and based on which for wards the m ulticast pack ets sent from the upstream router.

3.4.2 IGMP

The Internet gr oup management protocol (IGMP) r uns between hosts and multicast routers for tracing and l ear nin g th e membership of the hos ts. A multicast router le ar ns whether there is a multicast member on a subnet connected to it by periodically sending IGMP Host-Query messages. A host sends IGMP Report messages for joining a multicast group. The S3600 series support both IGMPv1 and IGMPv2.

3.4.3 PIM-DM

The protocol-independent multicast (PIM) runs between multicast routers. Using PIM, a multicast router traces and learns which multicast packets are to be forwarded to other routers, and then transmits them to the LANs connected to the multicast routers.

The protocol independent multicast-dense mode (PIM-DM) is applied to a m ulticast environment where multicast group members are dense. In PIM-DM, a router assumes that all other routers agree to forward multicast packets for m ulticast groups. If the router receives a multicast packet but has no directly connected multicast group member or PIM neighbor, it sends a Prune message back to the multicast source. The subsequent multicast packets ar e not to be transmitted to this router. By using this flood-prune mechanism , IM-DM cr eates a m ulticast distr ibution tree with the m ulticas t source as the root.

3.4.4 PIM-SM

Different from PIM-DM, the protocol independent multicast-sparse mode (PIM-SM) applies to a multicast environment where multicast group members are sparse. In PIM-SM, a router assumes that none of other routers agree to forward multicast packets for multicast groups, unless they declare so. If a host wants to join a multicast group, the multicast router that is directly connected to it sends a PIM Join message to the rendezvous point (RP) where the host is registered. The RP then forwards the Join message to the multicast source. In PIM-SM, the multicast packet is forwarded along a shared distribution tree.

Page 67

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-8

3.4.5 MVR

MVR provides the abil ity to continuousl y send multicast s treams in a multicast V LAN and isolate the streams from user VLANs. For a user to receive the multicast streams, MVR requires the user port to join the multicast VLAN.

In the current multicast mode, when users in different VLANs demand the same multicast stream, the stream will be copied to each of the VLANs. This greatly wastes bandwidth. In the multicast VLAN mode, the multicast stream travels in only one VLAN before it reaches the users. This greatly reduces multicast traffic and thus saves bandwidth.

After a port is added t o an IGSP-enabled m ulticast VLAN, the multicast entries are added to the multicast VLAN that the port belongs to, whichever VLAN the packets that the port receives belong to.

3.5 IRF

3.5.1 Basic IRF

Basic IRF provides:

 Basic Intelligent Resilient Framework (IRF) where devices are connected through

fabric ports for centralized management.

 Support the feature includes DDM (Distributed Device Management).  Support Dynamic link aggregation through Link Aggregation Control Protocol

(LACP) on one device.

3.5.2 Enhanced IRF

Enhanced IRF (Intelligent Resilient Framework) is a technology to construct intelligent resilient framework . With IRF, you can connect multiple IRF-supported switches that are of the same type (called units) to form a “device union” or a fabric. You are allowed to:

 The Enhanced Intelligent Resilient Framework (IRF) feature, where the

IRF-supported switches tha t are of the same type (called units ) are conn ected to form a “device union” or a fabric. T rough a fabric, you c an (1) manage m ultiple devices but with one connection and one IP address, thus decreasing the overheads; (2) expand the net work by adding devices as des ired, thus protecting the existing investm ent; and (3) have high reliability of N + 1 redundancy, thus avoiding single point failures which can result in service interruption.

3.6 QoS

Quality of service (QoS) pr ovides differentiated ne twork services to ac commodate to various demands.

3.6.1 Traffic Classification

Traffic classification is to classify packets to facilitate the subsequent packet processing conducted by a switch.

In traffic classification, a rule is specified for discriminating packets compliant with some characteristics. Class ification rules can be very simpl e; for example, packets can be sorted by the priority defined in the type of service (ToS) field in the IP header . They can also be very complex; for example, packets can be sorted by any combination of MAC address, IP protocol type, source (host or network) address, destination (host or network) address, and even a pplicat ion port number, which involve the la yers of data link, network, and transport.

3.6.2 Traffic Policing/Traffic Assurance

Traffic policing polices the traffic matching a traffic classification rule on the port where the packets are received, so tha t the traffic can effective ly use the assigned ne twork resources such as bandwidth.

Traffic policing mainly functions to limit the speed of an inp ut p or t an d th er eby monitor the traffic that enters its connected network. When packets arrive at the port at a speed exceeds the assigned bandwidth, they are either dropped or assigned a new preference.

Bandwidth assurance refers to assuring the minimum bandwidth for a special traffic so that it can satisf y such QoS requirements as packet loss rate, delay, jitter even when network congestion occurs.

3.6.3 Port Flow Control

Port flow control is us ed for congestion management. Co ngestion occurs when the network cannot reach the committed or negotiated performance specifications (such as speed).

When congestion occ urs, the switch transmits a pause frame to the corresponding connection and notifies the peer to paus e for a period of tim e befor e transm itting data again, so as to reduce the incoming traffic on the network. The port control takes effect on all traffic.

Page 69

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-10

3.6.4 Port Rate-Limiting

Port rate-limiting is applied to transmit ports to monitor and limit the bandwidth allocated to traffic. For this purpose, a rate threshold is set on the transmit ports and the traffic that exceeds the threshold is discarded.

3.6.5 Port Mirroring

Port mirroring monitors packets on a specific port. When this function is applied, data packets on a mirroring port are copied to its monitor

port for network test and troubleshooting.

3.6.6 Traffic Mirroring

Traffic mirroring monitors the traffic that matches the traffic classification rule. This function is to co p y th e data packets that match th e tr aff ic clas s ific ation ru le t o th e

monitor port for network detection and trouble shooting.

3.6.7 Remote Port Mirroring

The remote port mirr oring feature introduces a new concept, m irroring group, to port mirroring. Multiple mirroring groups can be configured on a switch.

Local port mirroring means to copy the packets on one or multiple ports of a switch to a monitoring port of the same switch for packet monitoring and analyzing. In remote port mirroring, the mirror ing ports and mirrored ports can span multiple network devices, that is, the mirrored ports and the mirroring ports can reside in different switches. Note that the remote port mirroring feature does not work cross a Layer 3 network.

3.6.8 Queue Scheduling

Queue scheduling applies to the situation where several packets to be forwarded compete for the resources. The S3600 series support three queue scheduling algorithms: strict priority (SP), weighted round robin (WRR) , and weighted fair queuing (WFQ).

I. SP

High

Queue

Figure 3-1 SP

The SP mec hanism applies to key services that ar e delay sensitive and must have priority when congestio n occ urs. In SP, packets are assigned to f our queues, namely, high-priority queue, medium-priority queue, normal priority queue, and low-priority queue (queue 3, 2, 1, and 0 respectively) with decreasing priorities.

SP schedules the packets in a strict priority order. It sends the packets in a queue only when the queue with a higher priority is empty. By putting the key service packets in the high priority queues, you can ensure that they can always be served first. At the same time the common service packets can be put in the low priority queues and transmitted when there are no key service packets waiting for transmission.

If congestion occurs and the high priority queues are occupied for a long time, however, the packets in the lower-priorit y queues are “starved” before obtaining services.

II. WRR

In WRR, there are four or eight egress queu es on each por t. The pack ets in different queues are processed in turn, so that every queue is assigned some time of service. If there are four queues on a port, they are each assigned a weight for obtaining resources: w3, w2, w1, and w0 respectively. On a 100 Mbps port for example, you can assigns the weights 50, 30, 10, 10 to the four queues with w3, w2, w1 and w0. Thus the lowest-pr iority queue can be guaranteed of a minimum bandwidth of 10 Mbps. This avoids the case that the packets in the low priori t y queues cannot be served, as in SP. More than that, WRR assigns service time slices flexibly to every queue. When a queue is empty, the next one is processed immediately. Thus it makes a full use of the bandwidth resources.

III. WFQ

WFQ classifies packets by flow. The packets with the same source IP address, destination IP address, source port number, destination port number, protocol, or TOS are regarded a flow and are assigned to the same queue. When WFQ dequeues

Page 71

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-12

packets, it assigns bandwidth to each flow according to their precedence, with a smaller precedence value indicating less bandwidth. If on a port there are eight flows wit h the precedence values of 0 , 1, 2, 3, 4, 5, 6, and 7 res pec ti vel y, then the total bandwidth is the sum of (precedence value + 1)s: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = 36.

The proportion of each flow’s bandwidth is: (flow precedence value + 1)/sum of (precedence value + 1)s. Then, the flows ' bandw id th proportion values are respectively: 1/36, 2/36, 3/36, 4/36, 5/36, 5/36, 6/36, 7/36, 8/36.

Another example: there ar e four flows, of which three have the pr ecedence of 4 and one has the precedence of 5; then the total bandwidth is (4 + 1) x 3 + (5 + 1) = 21.

The bandwidth proportion valu es of the flows with precedence 4 are 5/21, and that of the flow with precedence 5 is 6/21.

S3600 series support five sc heduling algorithms that can be set based on port and queue at the same time: Strict Priority (SP), Weighted Roun d Rob in (WRR), Weighted Fair Queue (WFQ), SP + WFQ, SP + WRR

3.6.9 Traffic Shaping

Traffic shaping is to control traffic output rate as such that packets can be output at an even rate. Normally , traffic shaping is applied on a device to adapt its output rate to the input rate of its connected downstream device so as to avoid unnecessary packet drop and congestion. It is different from traffic policing in the sense that it buffers the packets that exceed the specified rate limit so that packets are sent out at an even spe ed, whereas traffic policing is t o discard th e pack ets. Besides , traffic shaping can r esult in the additional delay that can be avoided in traffic policing.

3.6.10 Priority Tag

The priority tag feature is used for setting new packet priority. The S3600 series provide some specific packets with the priority tag service. The tags

include ToS priority, differentiated services codepoint priority (DSCP), and 802.1p priority.

3.6.11 QoS Profile

Cooperating with 802.1x authentication, the QoS profile feature dynamically provides a set of pre-defined QoS functions for successfully authenticated users.

After an 802.1x user p asses the authentication, the switch finds the profile according to the username-to-profile corresponding rel ati onsh ip c onf igured on the AA A server, and

Page 72

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-13

dynamically delivers the profile to the user access port, thus providing a set of pre-defined service quality guarantees for the user.

Currently, the QoS profile feature on the switch can pr ovide the following functions: packet filtering, traffic monitoring, and priority tagging.

3.7 web cache redire ctio n

The hypertext transfer protocol (HTTP) is one of the m os t c ommonly used methods to access the Internet. web cache redirection is provided to reduce the load on WAN links and to increase the speed, as shown in Figure 3-2:

Internet

Figure 3-2 web cache redirection

In the diagram, the PC is a user on a LAN attached to the switch. The Web Cache is a server that stores the frequently visited internet websites of the WAN users. Once web cache redirection is enabled, the HTTP traffic that the user sends to the In ternet is redirected to the Web Cache. If the Web Cache has the contents that the user needs, it returns the content direct l y to the user and t he us er does not need to actually log ont o the Internet; if it does not have the contents, then the user needs to get the information from the Internet.

3.8 NTP

Clock synchronization among devices is important for a complex network. The network time protocol (NTP) is a TCP/IP protocol that releases accurate time on a network.

NTP provides consistency guarantee for the following applications:

 When increm ent backup is performed between a backup server and a clie nt, it

ensures the clock between the two system be synchronous.

 When multiple systems are used to deal with complex events, it ensures the

correct order of these events.

 It ensures the RPC between systems be normally performed.  It provides tim e information about suc h operations as system login of users , file

modification for application program.

3.9 Security

The popularity of network applications, especially in some sensitive occasions (e-commerce for example), highl ights the iss ue of network security. The S3600 series provide these network security features:

 Hierarchical user management and password protection  MAC address black hole  MAC address learning limit  MAC address and port binding  SSH  802.1x authentication  Centralized MAC address authentication  DUD authentication  Local and RADIUS authentication  Port isola tion

With respect to filtering and authenticating Ethernet frames and packets from the upper layers, the S3600 series support:

 ACL, with which information is filtered at layers 2 through 4 (such as based on port,

by source/destination MAC addr ess, by sour ce/destinatio n IP addres s, or b y the type of upper layer protocol).

 RIPv2/OSPFv2 packet authentication with the clear text and MD5 approaches  Encrypted authentication of SNMPv3

3.9.1 Terminal Access User Classification

The S3600 series protect command lines in a hierarchical way by dividing the command lines into four levels: visitor, monitor, operator, and administrator. Commensurate with the command division, login users are classified into four levels. A login user can use only the commands equal to or lower than its level.

3.9.2 SSH

When users log onto the Ethernet switch from an insecure network, Secure Shell (SSH) offers security information protection and powerful authentication function to safeguard the Ethernet switch from attacks such as IP address spoofing and plain text ciphe r interception. The Ethernet switch can accept multiple SSH customer connections at the

Page 74

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-15

same time. The SSH client allows users to connect to the Ethernet switches and UNIX mainframes that support SSH servers.

3.9.3 Port Isolation

Port isolation means layer 2 isolation of the ports in the same VLAN so that layer 2 relay cannot be done bet ween a port and another ( or another group of ) port, but it can communicate with the port in the upper layer. It prevents visiting between the p orts, effectively controls unnecessary broadcasting and increases the network throughput.

3.9.4 Packet Filter

Packet filter filters invalid or non-interesting data packets. The switch filters each packet based on the defined rules, by comparing the source or destination address for example. With packet filter, session state is ignored and data is not anal yzed. You can define which packets are permitted and which are denied.

3.9.5 IEEE 802.1X Au t hen t icatio n

IEEE 802.1x is virtually a port based network acc ess control protocol. As the n ame implies, the NAS on a LAN authenticates and controls the connected customer premises equipment (C PE) at the port level. If the CPE connected to a por t passes authentication, it is al lo wed t o acc es s t he LAN res our ces . O therwise, it is rejected j us t like its physical link is disconnected.

In implementing 802.1x, the Ethernet switches not only support the port-based access authentication, but also extend and optimize it by:

 Allowing a physical port to be connected to several terminals.  Supporting access control (that is us er auth enticati on) based on MAC address in

addition to port.

The system thus becomes securer and more operational and manageable. Note that, although 802.1x provides an implementation scheme for user authentication,

the protocol itself is not enough to im plement the scheme. The NAS administrat ors, however, can use RADIUS or local au thenticat ion to co m plete the us er authen ticat ion with 802.1x.

3.9.6 Centralized MAC Address Authentication

Centralized MAC address authent ication: the serv er or the Ethernet s witch s tores th e information on user MAC addresses. Once a new user is detected, the switch authenticates the user by taking its MAC address as its user name and pass word. It searches the MAC addresses table in the server or the switch for the user ’s MAC

Page 75

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-16

address. If found, the user is authenticated and the MAC address will be automatically added to the correspond ing port; if not, t he authenticat ion fails and the pac ket wil l be discarded. This authentication method does not involve the client, the client’s own MAC address is taken as its user name and password.

3.9.7 MAC Address Learning Limit

MAC address learning limit: limits the number of MAC addresses learned by an Ethernet switch port. The num ber ranges from 0 to 4k. The static MAC addresses added on the port are not affected.

3.9.8 MAC Address and Port Binding

After a MAC addr ess is bound with a port, this MAC addres s can only access the network through this port.

3.9.9 DUD Authentication

With the disconnect unauthorized device (DUD) function enabled, the switch filters out all the traffic of a connected device once it detects that the device is unauthorized.

3.9.10 MAC Address Blac k Ho le

On a S3600 series switch, you can enable the black hole function and configure a black hole list. When the switch receives a packet with a source or destination MAC address in the black hole, it drops the packet.

3.9.11 AAA/RADIUS/HWTACACS

The S3600 series support user authentication at the local or with RADIUS servers that are based on 802.1x or its extension.

I. AAA

AAA is the abbreviation of Auth entic ation, Auth orizat ion a nd Acc ountin g. It pro vides a uniform framework to configure the security functions including authentication, authorization, and accounting. Actually, it offers a way to control the n etwork s ecurity, which can be implemented with RADIUS

AAA performs the following services:

 Authenticati on: Au the ntic at es if the user can access the network sever.  Authorization: Authorizes the user with specified services.  Accounting: Tracks the network resources consumed by users.

Page 76

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-17

II. RADIUS

RADIUS is a distributed system in the client/s erver model. It can fend off inva lid u s er s and is often used in a net wor k enviro nment where both h igh s ecur ity and remote user access are desired. For example, it can be used to manage the access based on

802.1x. RADIUS is based on the client/server model where user authentication always involves

a device that can provide the proxy function, such as NAS. Between the RADIUS client and server, the exchanged m essages are authentic ated using a shar ed ke y and us er passwords are sent encrypted over the network. The security is thus ensured.

III. HWTACACS

Huawei terminal access controller access control system (HWTACACS) is an enhanced security protoc ol based on TACACS (RFC 1492). Sim ilar to the RADIUS protocol, HWTACACS adopts the server-client mode to implement authentication, authorization and acc ounting (AAA) of d ifferent access users, including PPP users, VPDN users and login users . (PPP: point t o p oint pro toc ol; VPDN: virtual private data network)

Compared with RADIUS, HWTACACS is more reliable in transmission and encryption, and so is more suitable for security control.

3.9.12 MAC-IP-Port Binding

After MAC-IP-port binding is enabled on a port, the port can pass IP and ARP packets for only those hosts whose IP and MAC addresses ha ve been bou nd to the por t. The binding configuration on the port neither affects the passing of other types of packets on the port, nor affects the other ports on the switch.

3.10 Reliability

3.10.1 VRRP

 Note:

A VRRP-enabled Ethernet switch can func tion as a router. The routers mentioned in this manual refer to common routers and VRRP-enabled Layer 3 switches.

Page 77

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-18

VRRP is a fault tolerance protocol which uses the standby mechanism to improve the reliability of establishing connections with a router.

VRRP assures reliability through grouping multiple routers on a LAN segment into one standby group. In a standby group, there is al wa ys an ac tive router (called the master router). This router functions as the virtual router, and other routers in the group function as the back up routers monitoring the mas ter router. When the master router fails, all the backup routers automatically elect a new master router to replace the original one. The new master router functions as the virtual router and provides routing service for the hosts on the network segment. The election and replacement process is short and smooth, and so the hosts on the network s egm ent c an us e the virt ua l router as usual to communicate with external devices continuously.

3.11 Cluster Management

3.11.1 HGMP

HGMP implements centralized management of devices, that is, HGMP uses one device to manage multiple devices . Current ly, HGMP includes two versi ons: HGMPv1 and HGMPv2. The S3600 series support HGMPv2 only.

In an administrative domain, HGMPv2 regards one switch as the command switch and other switches in the domain as member s witches. The command switch is used to manage other switches, and the member switches are the switches being m anaged. After HGMPv2 is enabl ed, t he net work adm inistr ator can use o ne c omm and switc h to manage multiple member switches. Public IP address setting is not necessary for member switches, which can be managed and maintained through the command switch.

3.12 QinQ

3.12.1 QinQ

QinQ means to encapsulate private VLAN tags in public VLAN tags in order that packets can be transported with two layers of VLAN tags through the backbone network (public network) of carriers. In public networks, packets are transferred by only outer-layer VLAN tags ( that is, public VLAN tags) while inner-layer VLAN tags (th a t is , private VLAN tags) are shielded.

Compared with Layer 2 VPN based on MPLS, QinQ has the following advantages:

 QinQ provides simpler Layer 2 VPN tunneling;

Page 78

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-19

 QinQ d oes not n eed the suppor t of sig naling protoco l. It can b e implem ented by

fully static configurations.

Primarily, QinQ can solve the following problems:

 QinQ relaxes the shortage of public VLAN IDs;  You can plan your own private V LAN IDs , whic h wil l not col lide with public VLAN

IDs;

 QinQ prov ides a simple Layer 2 VPN solution for small-sized m etropolitan area

networks (MANs) and enterprise networks.

3.12.2 QinQ BPDU Tunnel

The feature works as follows: On an i ngr es s de v ic e of a ne t work, the MAC address of an inbound BPDU packet is replaced by a special MAC address (01:00:0C:CD:CD:D0), and then the packet is encapsulated again as a BPDU packet on the peer egress device of the network. In this way, BPDU packets are transmitted transparently through the carrier network. Thus, both the user network and the carrier network can have their own STP trees, which do not interfere with each other.

3.13 GARP/GVRP

3.13.1 GARP

Generic attribute registration protocol (GARP) provides a way for the switching members in the sam e switching network to distribute, transmit and regis ter a kind of information, such as VLAN information and multicast group address information.

GARP members, which ca n be terminal workstations or r outing switches, exchange information in the way of messages. All the attr ibute information to be register ed is transmitted to all the routing switches in the same switching network. Through the GARP mechanism, the conf iguration i nform ation of a GARP m ember is transm itted t o the whole switching net work . A GARP member tells other GARP members to register or deregister its attribute inf ormation through declaratio ns or reclamation declarations, and registers or deregisters the attribute information of other GARP members according to their declarations or reclamation declarations.

GARP itself does not exist as an entit y in a routing switch. The application entities conforming to GARP are nam ed GARP applicati ons, currently including GARP VLAN registration protocol ( GVRP) and GARP m ulticast registration protocol ( GMRP). The protocol packets of the sam e type of GARP applicat ion (GVRP or GMRP) have the same destination MAC address (a particular multicas t address), and the destination MAC address of GVRP is different from that of GMRP. When a GARP-enabled routing switch receives GARP applicat ion packets, it classifies these packets based on their

Page 79

System Description H3C S3600 Series Ethernet Switches

Chapter 3 Software Features

3-20

destination MAC ad dress es and then submits them to different applications (GVRP or GMRP) for processing.

3.13.2 GVRP

GVRP is a GARP application. Based on the GARP mechanism, GVRP maintains dynamic VLAN registration information in a routing switch and transmits the information to other routing switches.

All GVRP-enabled routing switches can receive VLAN registration inform ation from other routing switches and update the local VLAN registration information (including the information about the current VLAN mem bers and the ports though which the VLAN members can be reached) dynamicall y. Additionally, a GARP-enabled routing switc h can transmit its local VLAN registration information (including the local static registration information c onfigured manual ly and the dynam ic registration i nformation from other routing switches ) to other routing s witches, so that all the G ARP-enabled routing switches in the same switching network have the consistent VLAN information.
