Summit.bk : 1OVRVW.FM Page 5 Thursday, June 18, 1998 9:27 AM SUMMARY OF FEATURES FULL-DUPLEX The Summit switch provides full-duplex support for all ports. Full-duplex allows frames to be transmitted and received simultaneously and, in effect, doubles the bandwidth available on a link. All 10/100 Mbps ports on the Summit autonegotiate for half- or full-duplex operation. PORT REDUNDANCY The Summit2, Summit3, and Summit48 have an optional redundant Gigabit Ethernet port.
Summit.bk : 1OVRVW.FM Page 6 Thursday, June 18, 1998 9:27 AM SUMMIT OVERVIEW LOAD SHARING Load sharing with Summit switches allows the user to increase bandwidth and resilience between switches by using a group of ports to carry traffic in parallel between switches. The sharing algorithm allows the switch to use multiple ports as a single logical port. For example, VLANs see the load-sharing group as a single virtual port. The algorithm also guarantees packet sequencing between clients.
Summit.bk : 1OVRVW.FM Page 7 Thursday, June 18, 1998 9:27 AM SUMMARY OF FEATURES The Summit supports up to 64 Spanning Tree Domains (STPDs). For more information on STP, refer to Chapter 7. QUALITY OF SERVICE (QOS) The Summit has policy-based Quality of Service (QoS) features that enable you to specify service levels for different traffic groups. By default, all traffic is assigned with the “normal” QoS policy profile.
Summit.bk : 1OVRVW.FM Page 8 Thursday, June 18, 1998 9:27 AM SUMMIT OVERVIEW NETWORK CONFIGURATION EXAMPLE As shown in Figure 1-2, the family of Summit switches offer a unique end-to-end LAN system solution. From the desktop, to the gigabit core, to the data center/server farm, there are Summit switches with an optimized hardware configuration to match the requirements. ExtremeWare software is common to all Summit switches, and allows for the same services to operate across the entire product family.
Summit.bk : 1OVRVW.FM Page 9 Thursday, June 18, 1998 9:27 AM NETWORK CONFIGURATION EXAMPLE In the gigabit core of the network, the Summit1 and Summit2 act as aggregators of Gigabit Ethernet links from the edge and data center switches, as well as Ethernet and Fast Ethernet links from legacy routers and hubs.

Summit.bk : 5VLAN.FM Page 1 Thursday, June 18, 1998 9:27 AM 5 Virtual LANs (VLANs) Setting up Virtual Local Area Networks (VLANs) on the Summit eases many time-consuming tasks of network administration while increasing efficiency in network operations. This chapter describes the concept of VLANs and explains how to implement VLANs on the Summit. OVERVIEW OF VIRTUAL LANS The term VLAN is used to refer to a collection of devices that communicate as if they were on the same physical LAN.
Summit.bk : 5VLAN.FM Page 2 Thursday, June 18, 1998 9:27 AM VIRTUAL LANS (VLANS) • VLANs provide extra security. Devices within each VLAN can only communicate with member devices in the same VLAN. If a device in VLAN Marketing must communicate with devices in VLAN Sales, the traffic must cross a routing device. • VLANs ease the change and movement of devices. With traditional networks, network administrators spend much of their time dealing with moves and changes.
Summit.bk : 5VLAN.FM Page 3 Thursday, June 18, 1998 9:27 AM TYPES OF VLANS For example, in Figure 5-1, ports 1, 2, and 5 are part of VLAN Marketing; ports 3, 4, and 6 are part of VLAN Sales; and ports 7 and 8 are in VLAN Finance.
Summit.bk : 5VLAN.FM Page 4 Thursday, June 18, 1998 9:27 AM VIRTUAL LANS (VLANS) Figure 5-2 illustrates a single VLAN that spans two switches. All ports on both switches belong to VLAN Sales. The two switches are connected using port 2 on Switch 1, and port 6 on Switch 2.
Summit.bk : 5VLAN.FM Page 5 Thursday, June 18, 1998 9:27 AM TYPES OF VLANS Figure 5-3 illustrates two VLANs spanning two switches. On Switch 1, ports 1-4 are part of VLAN Accounting; ports 5 - 8 are part of VLAN Engineering. On Switch 2, ports 1-4 are part of VLAN Accounting; ports 5 - 8 are part of VLAN Engineering. VLAN Accounting spans Switch 1 and Switch 2 by way of a connection between Switch 1 port 2 and Switch 2 port 4.
Summit.bk : 5VLAN.FM Page 6 Thursday, June 18, 1998 9:27 AM VIRTUAL LANS (VLANS) USES OF TAGGED VLANS Tagging is most commonly used to create VLANs that span switches. The switch-to-switch connections are typically called trunks. Using tags, multiple VLANs can span multiple switches using one or more trunks. In a port-based VLAN, each VLAN requires its own pair of trunk ports, as shown in Figure 5-3. Using tags, multiple VLANs can span two switches with a single trunk.
Summit.bk : 5VLAN.FM Page 7 Thursday, June 18, 1998 9:27 AM TYPES OF VLANS Figure 5-4 illustrates the physical view of a network that uses tagged and untagged traffic.

Summit.bk : 5VLAN.FM Page 10 Thursday, June 18, 1998 9:27 AM VIRTUAL LANS (VLANS) VLANs that are automatically created using GVRP with the VLANid 10 are given names in the following format: gvrp vlan xxxx where xxxx is the VLANid (in decimal) that is discovered by GVRP. These VLANs are not permanently stored in NVRAM, and you cannot add or remove ports from these VLANs. GVRP assumes that the VLANs for which it carries information operate using VLAN tags, unless explicitly configured otherwise.
Summit.bk : 5VLAN.FM Page 11 Thursday, June 18, 1998 9:27 AM TYPES OF VLANS PROTOCOL-BASED VLANS Protocol-based VLANs enable you to define a packet filter that the Summit uses as the matching criteria to determine if a particular packet belongs to a particular VLAN. Protocol-based VLANs are most often used in situations where network segments contain hosts running multiple protocols. For example, in Figure 5-7, the hosts are running both the IP and NetBIOS protocols.
Summit.bk : 5VLAN.FM Page 12 Thursday, June 18, 1998 9:27 AM VIRTUAL LANS (VLANS) PREDEFINED PROTOCOL FILTERS The following protocol filters are predefined on the Summit: • IP • IPX • NetBIOS • DECNet • IPX_8022 • IPX_SNAP • AppleTalk DEFINING PROTOCOL FILTERS If necessary, you can define a customized protocol filter based on EtherType, LLC, and/or SNAP. Up to six protocols may be part of a protocol filter.
Summit.bk : 5VLAN.FM Page 13 Thursday, June 18, 1998 9:27 AM VLAN NAMES — snap — Ethertype inside an IEEE SNAP packet encapsulation. The values for snap are the same as the values for etype, described previously. config protocol fred add llc feff config protocol fred add snap 9999 A maximum of seven protocol filters, each containing a maximum of six protocols, can be defined, however no more than seven protocol should be active and configured for use.
Summit.bk : 5VLAN.FM Page 14 Thursday, June 18, 1998 9:27 AM VIRTUAL LANS (VLANS) VLAN names are locally significant. That is, VLAN names used on one switch are only meaningful to that switch. If another switch is connected to it, the VLAN names have no significance to the other switch. The exception to this is when a switch is connected to a Summit Virtual Chassis. In this case, the VLAN name is used as part of the connectivity negotiation process.

Summit.bk : 6FDB.FM Page 1 Thursday, June 18, 1998 9:27 AM 6 Switch Forwarding Database (FDB) This chapter describes the contents of the switch forwarding database (FDB), how the FDB works, and how to configure the FDB. OVERVIEW OF THE FDB The Summit maintains a database of all media access control (MAC) addresses received on all of its ports. It uses the information in this database to decide whether a frame should be forwarded or filtered.
Summit.bk : 6FDB.FM Page 2 Thursday, June 18, 1998 9:27 AM SWITCH FORWARDING DATABASE (FDB) switch is reset or a power off/on cycle occurs. For more information about setting the aging time, refer to the section “Configuring FDB Entries,” later in this chapter. • Non-aging entries — If the aging time is set to zero, all aging entries in the database are defined as static, non-aging entries. This means that they do not age, but they are still deleted if the switch is reset.
Summit.bk : 6FDB.FM Page 3 Thursday, June 18, 1998 9:27 AM CONFIGURING FDB ENTRIES ASSOCIATING A QOS PROFILE WITH AN FDB ENTRY You can associate a QoS profile with a MAC address (and VLAN) of a device that will be dynamically learned. The FDB treats the entry like a dynamic entry (it is learned, it can be aged out of the database, and so on). The switch applies the QoS profile as soon as the FDB entry is learned.
Summit.bk : 6FDB.FM Page 4 Thursday, June 18, 1998 9:27 AM SWITCH FORWARDING DATABASE (FDB) Table 6-1: FDB Configuration Commands (continued) Command Description disable learning port Disables MAC address learning on one or more ports for security purposes. If MAC address learning is disabled, only broadcast traffic and packets destined to a permanent MAC address matching that port number, are forwarded. The default setting is enabled.
Summit.bk : 6FDB.FM Page 5 Thursday, June 18, 1998 9:27 AM DISPLAYING FDB ENTRIES DISPLAYING FDB ENTRIES To display FDB entries, use the command show fdb {all | | vlan | | permanent | qos} where the following is true: • all — Displays all FDB entries. • mac_address — Displays the entry for a particular MAC address. • vlan — Displays the entries for a VLAN. • portlist — Displays the entries for a port. • permanent — Displays all permanent entries.

Summit.bk : 7STP.FM Page 1 Thursday, June 18, 1998 9:27 AM 7 Spanning Tree Protocol (STP) Using the Spanning Tree Protocol (STP) functionality of the Summit makes your network more fault tolerant. The following sections explain more about STP and the STP features supported by the switch. STP is a part of the 802.1D bridge specification defined by the IEEE Computer Society. To explain STP in terms used by the 802.1D specification, the Summit will be referred to as a bridge.
Summit.bk : 7STP.FM Page 2 Thursday, June 18, 1998 9:27 AM SPANNING TREE PROTOCOL (STP) A port can belong to only one STPD. If a port is a member of multiple VLANs, then all those VLANs must belong to the same STPD. The key points to remember when configuring VLANs and STP are the following: • Each VLAN forms an independent broadcast domain. • STP blocks paths to create a loop-free environment. • When STP blocks a path, no data can be transmitted or received on the blocked port.
Summit.bk : 7STP.FM Page 3 Thursday, June 18, 1998 9:27 AM STP CONFIGURATIONS Two STPDs are defined: • STPD1 contains VLANs Sales and Personnel. • STPD2 contains VLANs Manufacturing and Engineering. The VLAN Marketing is a member of the default STPD, but not assigned to either STPD1 or STPD2.
Summit.bk : 7STP.FM Page 4 Thursday, June 18, 1998 9:27 AM SPANNING TREE PROTOCOL (STP) Within a single STPD, you must be extra careful when configuring your VLANs. Figure 7-2 illustrates a network that has been incorrectly set up using a single STPD so that the STP configuration disables the ability of the switches to forward VLAN traffic.
Summit.bk : 7STP.FM Page 5 Thursday, June 18, 1998 9:27 AM CONFIGURING STP CONFIGURING STP ON THE ON THE SUMMIT SUMMIT STP configuration involves the following actions: • Create one or more STP domains using the following command: create stpd STPD, VLAN, and QoS profile names must all be unique. For example, a name used to identify a VLAN cannot be used when you create an STPD or a QoS profile.
Summit.bk : 7STP.FM Page 6 Thursday, June 18, 1998 9:27 AM SPANNING TREE PROTOCOL (STP) Table 7-1 shows the commands used to configure STP. Table 7-1: STP Configuration Commands Command Description create stpd Creates an STPD. When created, an STPD has the following default parameters: ■ Bridge priority — 32,768 ■ Hello time — 2 seconds ■ Forward delay — 15 seconds enable stpd [ | all] Enables the STP protocol for one or all STPDs. The default setting is disabled.
Summit.bk : 7STP.FM Page 7 Thursday, June 18, 1998 9:27 AM CONFIGURING STP ON THE SUMMIT Table 7-1: STP Configuration Commands (continued) Command Description config stpd port cost Specifies the path cost of the port in this STPD. config stpd port priority The range is 1 through 65,535. The switch automatically assigns a default path cost based on the speed of the port, as follows: ■ For a 10Mbps port, the default cost is 100.

Summit.bk : 7STP.FM Page 9 Thursday, June 18, 1998 9:27 AM DISABLING DISABLING AND AND RESETTING STP RESETTING STP To disable STP or return STP settings to their defaults, use the commands listed in Table 7-2. Table 7-2: STP Disable and Reset Commands Command Description delete stpd Removes an STPD. An STPD can only be removed if all VLANs have been deleted from it. disable stpd [ | all] Disables the STP mechanism on a particular STPD, or for all STPDs.

Summit.bk : 8QOS.FM Page 1 Thursday, June 18, 1998 9:27 AM 8 Quality of Service (QoS) This chapter describes the concept of Quality of Service (QoS) and explains how to implement QoS on the Summit. OVERVIEW OF QUALITY OF SERVICE QoS is a feature of the Summit that allows you to specify different service levels for outbound traffic. QoS is an effective control mechanism for networks that have heterogeneous traffic patterns. Using QoS, you can specify the service that a traffic type receives.
Summit.bk : 8QOS.FM Page 2 Thursday, June 18, 1998 9:27 AM QUALITY OF SERVICE (QOS) QoS profiles are assigned to traffic classifications, independent of the QoS mode chosen, in order to modify switch forwarding behavior. QOS MODE There are two modes of QoS. Ingress mode, the default, can use a wide variety of traffic classifications, but has a limitation of being able to use only the default four QoS profiles. You can modify the bandwidth parameters of the default QoS profiles.
Summit.bk : 8QOS.FM Page 3 Thursday, June 18, 1998 9:27 AM BUILDING BLOCKS — Medium — High A QoS profile does not alter the behavior of the switch until it is assigned to a traffic classification. The details of the default profiles are shown in Table 8-1.
Summit.bk : 8QOS.FM Page 4 Thursday, June 18, 1998 9:27 AM QUALITY OF SERVICE (QOS) • Destination MAC address — When making a permanent FDB entry, you can provide a QoS profile. You can also provide a QoS profile that will be bound to a dynamic FDB entry when the MAC address is learned.
Summit.bk : 8QOS.FM Page 5 Thursday, June 18, 1998 9:27 AM BUILDING BLOCKS EGRESS TRAFFIC GROUPINGS Egress traffic groupings include the following: • IP destination address — A specific QoS profile can be associated with an IP destination address, or range of IP destination addresses specified using a subnet mask. The QoS parameters are dynamically associated with a route when the route table is built.
Summit.bk : 8QOS.FM Page 6 Thursday, June 18, 1998 9:27 AM QUALITY OF SERVICE (QOS) PRIORITIZATION Prioritization is used when there is bandwidth contention for transmission on a port. The four levels of priority are used as a mechanism for resolving the contention between traffic groups. If traffic groups have the same priority, a “round-robin” algorithm is applied. CREATING AND CONFIGURING A QOS PROFILE Up to 28 custom QoS profiles can be created on the Summit in egress mode.
Summit.bk : 8QOS.FM Page 7 Thursday, June 18, 1998 9:27 AM PORT QUEUE MONITOR You can assign a QoS profile to an IP address by using the following command: config ipqos [add | delete] qosprofile PORT QUEUE MONITOR There are four queues per physical port in the Summit. In ingress mode, the four QoS profiles align to the four queues (for example, qp1 to the first queue, qp2 to the second queue, and so on).
Summit.bk : 8QOS.FM Page 8 Thursday, June 18, 1998 9:27 AM QUALITY OF SERVICE (QOS) CONFIGURING QOS Table 8-4 describes the commands used to configure QoS. Table 8-4: QoS Configuration Commands Command Description enable pace Enables recognition of the PACE bit. Available in ingress mode, only. create qosprofile Creates a QoS profile.
Summit.bk : 8QOS.FM Page 9 Thursday, June 18, 1998 9:27 AM CONFIGURING QOS SAMPLE INGRESS MODE QOS CONFIGURATION The following ingress mode example modifies an existing QoS profile and applies it to a VLAN traffic grouping. The priority parameter, although required, is ignored when configuring a default QoS profile in ingress mode.

Summit.bk : 9ROUT.FM Page 1 Thursday, June 18, 1998 9:27 AM 9 IP Unicast Routing This chapter describes how to configure IP routing on the Summit. It assumes that you are already familiar with IP unicast routing. If not, refer to the following publications for additional information: RFC 1058 — Routing Information Protocol RFC 1256 — ICMP Router Discovery Messages RFC 1812 — Requirements for IP Version 4 Routers For more information on routing protocols, refer to Chapter 10.
Summit.bk : 9ROUT.FM Page 2 Thursday, June 18, 1998 9:27 AM IP UNICAST ROUTING ROUTER INTERFACES The routing software and hardware routes IP traffic between router interfaces. A router interface is simply a VLAN that has an IP address assigned to it. As you create VLANs with IP addresses belonging to different IP subnets, you can also choose to route between the VLANs. Both the VLAN switching and IP routing function occur within the Summit.
Summit.bk : 9ROUT.FM Page 3 Thursday, June 18, 1998 9:27 AM OVERVIEW POPULATING THE OF IP UNICAST ROUTING ROUTING TABLE The Summit maintains an IP routing table for both network routes and host routes.
Summit.bk : 9ROUT.FM Page 4 Thursday, June 18, 1998 9:27 AM IP UNICAST ROUTING A static route must be associated with a valid IP subnet. An IP subnet is associated with a single VLAN by its IP address and subnet mask. If the VLAN is subsequently deleted, the static route entries using that subnet must be deleted manually. MULTIPLE ROUTES When there are multiple, conflicting choices of a route to a particular destination, the router picks the route with the longest matching network mask.
Summit.bk : 9ROUT.FM Page 5 Thursday, June 18, 1998 9:27 AM OVERVIEW OF IP UNICAST ROUTING Once configured, the Summit responds to ARP Requests on behalf of the device as long as the following conditions are satisfied: • The valid IP ARP Request is received on a Summit router interface. • The target IP address matches the IP address configured in the proxy ARP table. • The proxy ARP table entry indicates that the switch should always answer this ARP Request (the always parameter must be applied).
Summit.bk : 9ROUT.FM Page 6 Thursday, June 18, 1998 9:27 AM IP UNICAST ROUTING The following rules apply when you are configuring IP multinetting: • A maximum of one IP address is associated with a router interface (or VLAN). • Multiple VLANs must be used to implement IP multinetting. • A maximum of four subnets are allowed on one multinetted port. • For multinetted segments that span multiple ports, you must configure all the multinetted VLANs with the same port assignment.
Summit.bk : 9ROUT.FM Page 7 Thursday, June 18, 1998 9:27 AM OVERVIEW OF IP UNICAST ROUTING 8 Assign the subnet to a physical port. config net21 add port 2 config net22 add port 2 9 Enable IP forwarding on the subnets. enable ipforwarding 10 Enable IP multinetting. enable multinetting 11 If you are using RIP, disable RIP on the dummy VLANs.
Summit.bk : 9ROUT.FM Page 8 Thursday, June 18, 1998 9:27 AM IP UNICAST ROUTING The following example configures the switch to have one multinetted segment (port 5) that contains three subnets (192.67.34.0, 192.67.35.0, and 192.67.37.0). It also configures a second multinetted segment consisting of two subnets (192.67.36.0 and 192.99.45.0). The second multinetted segment spans three ports (port 8, port 9, and port 10). RIP is enabled on both multinetted segments.

Summit.bk : 10PROT.FM Page 1 Thursday, June 18, 1998 9:27 AM 10 Routing Protocols This chapter describes the IP unicast routing protocols available on the Summit. It assumes that you are already familiar with IP unicast routing.
Summit.bk : 10PROT.FM Page 2 Thursday, June 18, 1998 9:27 AM ROUTING PROTOCOLS RIP VERSUS OSPF The distinction between RIP and OSPF lies in the fundamental differences between distance vector protocols and link state protocols. Using a distance vector protocol, each router creates a unique routing table from summarized information obtained from neighboring routers.
Summit.bk : 10PROT.FM Page 3 Thursday, June 18, 1998 9:27 AM OVERVIEW OVERVIEW OF OF RIP RIP RIP is an Interior Gateway Protocol (IGP) first used in computer routing in the ARPAnet as early as 1969. It is primarily intended for use in homogeneous networks of moderate size. To determine the best path to a distant network, a router using RIP always selects the path that has the least number of hops. Each router that data must traverse is considered to be one hop.
Summit.bk : 10PROT.FM Page 4 Thursday, June 18, 1998 9:27 AM ROUTING PROTOCOLS TRIGGERED UPDATES Triggered updates occur whenever a router changes the metric for a route, and it is required to send an update message immediately, even if it is not yet time for a regular update message to be sent. This will generally result in faster convergence, but may also result in more RIP-related traffic.
Summit.bk : 10PROT.FM Page 5 Thursday, June 18, 1998 9:27 AM OVERVIEW OVERVIEW OF OF OSPF OSPF OSPF is a link state protocol that distributes routing information between routers belonging to a single IP domain, also known as an autonomous system. In a link state routing protocol, each router maintains a database describing the topology of the autonomous system. Each participating router has an identical database maintained from the perspective of that router.
Summit.bk : 10PROT.FM Page 6 Thursday, June 18, 1998 9:27 AM ROUTING PROTOCOLS The three types of routers defined by OSPF are as follows: • Internal Router (IR) An internal router has all of its interfaces within the same area. • Area Border Router (ABR) An ABR has interfaces in multiple areas. It is responsible for exchanging Summary Advertisements with other ABRs. • Autonomous System Border Router (ASBR) An ASBR acts as a gateway between OSPF and other routing protocols, or other autonomous systems.
Summit.bk : 10PROT.FM Page 7 Thursday, June 18, 1998 9:27 AM OVERVIEW OF OSPF VIRTUAL LINKS In the situation when a new area is introduced that does have a direct physical attachment to the backbone, a virtual link is used. A virtual link provides a logical path between the ABR of the disconnected area and the ABR of the backbone. A virtual link must be established between two ABRs that have a common area, with one ABR connected to the backbone. Figure 10-2 illustrates a virtual link.
Summit.bk : 10PROT.FM Page 8 Thursday, June 18, 1998 9:27 AM ROUTING PROTOCOLS CONFIGURING RIP Table 10-1 describes the commands used to configure RIP. Table 10-1: RIP Configuration Commands Command Description enable rip Enables RIP.
