SUMMIT.BK Page 2 Thursday, September 25, 1997 12:33 PM SUMMIT OVERVIEW SUMMARY OF FEATURES The Summit family of switches is comprised of two models: the Summit1 and the Summit2.
SUMMIT.BK Page 3 Thursday, September 25, 1997 12:33 PM SUMMARY OF FEATURES Figure 1-1 shows the front view of the Summit1. Unit status LEDs Port status LEDs Gigabit Ethernet ports Gigabit Ethernet ports Figure 1-1: Summit1 front view The Summit2 is a workgroup switch featuring sixteen 10Base-T/100Base-TX ports, two Gigabit Ethernet uplinks, and one redundant Gigabit Ethernet uplink. The 10Base-T/100Base-TX ports use standard RJ-45 connectors.
SUMMIT.BK Page 4 Thursday, September 25, 1997 12:33 PM SUMMIT OVERVIEW 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 has an optional redundant Gigabit Ethernet port.
SUMMIT.BK Page 5 Thursday, September 25, 1997 12:33 PM SUMMARY OF FEATURES ¥ It helps to control broadcast trafÞc. If a device in VLAN marketing transmits a broadcast frame, only VLAN marketing devices receive the frame. ¥ It provides extra security. Devices in VLAN marketing can only communicate with devices on VLAN sales using a device that provides routing services. ¥ It eases the change and movement of devices on networks.
SUMMIT.BK Page 6 Thursday, September 25, 1997 12:33 PM SUMMIT OVERVIEW IP UNICAST ROUTING The Summit can route IP trafÞc between the VLANs that are conÞgured as virtual router interfaces. Both dynamic and static IP routes are maintained in the routing table. RIP version 1 and RIP version 2 are supported. For more information on IP unicast routing, see Chapter 9. NETWORK CONFIGURATION EXAMPLES This section describes where to position the Summit1 and Summit2 within your network.

SUMMIT.BK Page 1 Thursday, September 25, 1997 12:33 PM 5 Virtual LANs (VLANs) Setting up Virtual Local Area Networks (VLANs) on the Summit eases many time-consuming tasks of network administration while increasing efÞciency 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 Page 2 Thursday, September 25, 1997 12:33 PM 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 trafÞc 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 Page 3 Thursday, September 25, 1997 12:33 PM 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. Marketing Finance Sales Figure 5-1: Example of a port-based VLAN Even though they are physically connected to the same Switch, for the members of the different VLANs to communicate, the trafÞc must go through the IP routing functionality provided in the Summit.
SUMMIT.BK Page 4 Thursday, September 25, 1997 12:33 PM 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. Sales Figure 5-2: Single port-based VLAN spanning two Switches In a port-based VLAN, to create multiple VLANs that span two Switches, a port on Switch 1 must be cabled to a port on Switch 2 for each VLAN you want to create.
SUMMIT.BK Page 5 Thursday, September 25, 1997 12:33 PM 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 Page 6 Thursday, September 25, 1997 12:33 PM 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 Page 7 Thursday, September 25, 1997 12:33 PM TYPES OF VLANS Figure 5-4 illustrates the physical view of a network that uses tagged and untagged trafÞc. MS M S M MS Switch 1 M = Marketing S = Sales 802.1Q Tagged server = Tagged port MS M S M S Switch 2 Figure 5-4: Physical diagram of tagged and untagged traffic Figure 5-5 shows a logical diagram of the same network.
SUMMIT.BK Page 8 Thursday, September 25, 1997 12:33 PM VIRTUAL LANS (VLANS) In Figure 5-4 and Figure 5-5: ¥ The trunk port on each Switch carries trafÞc for both VLAN Marketing and VLAN Sales. ¥ The trunk port on each Switch is tagged. ¥ The server connected to port 1 on Switch 1 has a NIC that supports 802.1Q tagging. ¥ The server connected to port 1 on Switch 1 is a member of both VLAN Marketing and VLAN Sales . ¥ All other stations use untagged trafÞc.
SUMMIT.BK Page 9 Thursday, September 25, 1997 12:33 PM TYPES OF VLANS The IP trafÞc has been divided into two IP subnets, 192.207.35.0 and 192.207.36.0. The subnets are internally routed by the Summit. The subnets are assigned different VLAN names, Finance and Personnel, respectively. The remainder of the trafÞc belongs to the VLAN named MyCompany. All ports are members of the VLAN MyCompany. 192.207.35.1 My Company 192.207.35.0 Finance 1 192.207.36.1 2 192.207.36.

SUMMIT.BK Page 11 Thursday, September 25, 1997 12:33 PM CONFIGURING VLANS ON THE SUMMIT DEFAULT VLAN The Summit ships with one default VLAN that has the following properties: ¥ The VLAN name is default. ¥ It contains all the ports on a new or initialized Switch. ¥ The default VLAN is untagged on all ports. It has an internal VLAN ID of 1. CONFIGURING VLANS ON THE SUMMIT This section describes the commands associated with setting up VLANs on the Summit.
SUMMIT.BK Page 12 Thursday, September 25, 1997 12:33 PM VIRTUAL LANS (VLANS) Table 5-1: VLAN Configuration Commands (continued) Command Description config vlan [add | delete] port {tagged | untagged} Adds and deletes ports. You can specify tagged and untagged port(s). By default, ports are untagged. config vlan protocol [ | any] Configures a protocol-based VLAN. If the keyword any is specified, then it becomes the default VLAN.
SUMMIT.BK Page 13 Thursday, September 25, 1997 12:33 PM DISPLAYING VLAN SETTINGS The following example creates a VLAN named Sales, with the VLAN ID 120. The VLAN uses both tagged and untagged ports. Ports 1 through 3 are tagged, and ports 4 and 7 are untagged. Note that when not explicitly speciÞed, ports are added as untagged. create config config config vlan sales sales tag 120 sales add port 1-3 tagged sales add port 4,7 The following example creates a protocol-based vlan named IPSales.

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 Þltered. FDB CONTENTS The database holds up to a maximum of 128K entries.
SUMMIT.BK Page 2 Thursday, September 25, 1997 12:33 PM 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 ÒConÞguring FDB Entries,Ó later in this chapter. ¥ Static entries Ñ If the aging time is set to zero, all aging entries in the database are deÞned as static, non-aging entries. This means that they do not age, but they are still deleted if the Switch is reset.
SUMMIT.BK Page 3 Thursday, September 25, 1997 12:33 PM DISPLAYING FDB ENTRIES Table 6-1: FDB Configuration Commands (continued) Command Description config fdb agingtime Configures the FDB aging time. The range is 15 through 1,000,000 seconds. The default value is 300 seconds. A value of 0 indicates that the entry should never be aged out.

SUMMIT.BK Page 1 Thursday, September 25, 1997 12:33 PM 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 Page 2 Thursday, September 25, 1997 12:33 PM 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 conÞguring 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 Page 3 Thursday, September 25, 1997 12:33 PM STP CONFIGURATIONS Two STPDs are deÞned: ¥ STPD1 contains VLANs Sales and Personnel. ¥ STPD2 contains VLANs Manufacturing and Engineering. The VLAN Marketing is not assigned to a STPD.
SUMMIT.BK Page 4 Thursday, September 25, 1997 12:33 PM SPANNING TREE PROTOCOL (STP) Within a single STPD, you must be extra careful when conÞguring your VLANs. Figure 7-2 illustrates a network that has been incorrectly set up using a single STPD so that the STP conÞguration disables the ability of the Switches to forward VLAN trafÞc.
SUMMIT.BK Page 5 Thursday, September 25, 1997 12:33 PM CONFIGURING STP ON THE SUMMIT CONFIGURING STP ON THE SUMMIT STP conÞguration 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 Page 6 Thursday, September 25, 1997 12:33 PM SPANNING TREE PROTOCOL (STP) Table 7-1 shows the commands used to conÞgure 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 Page 7 Thursday, September 25, 1997 12:33 PM CONFIGURING STP ON THE SUMMIT Table 7-1: STP Configuration Commands (continued) Command Description config stpd priority Specifies the priority of the STPD. By changing the priority of the STPD, you can make it more or less likely to become the Root Bridge. The range is 0 through 65,535. The default setting is 32,768. A setting of 0 indicates the highest priority.

SUMMIT.BK Page 9 Thursday, September 25, 1997 12:33 PM DISABLING AND RESETTING STP DISABLING AND 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 Page 1 Thursday, September 25, 1997 12:33 PM 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 trafÞc. QoS is an effective control mechanism for networks that have heterogeneous trafÞc patterns. Using QoS, you can specify the service that a trafÞc type receives.
SUMMIT.BK Page 2 Thursday, September 25, 1997 12:33 PM QUALITY OF SERVICE (QOS) QOS MODE The QoS mode for the Switch determines with which types of trafÞc classiÞcations the Switch will be dealing, explicit or implicit. The default is implicit. If you want to change the QoS mode, it requires performing the change, saving the conÞguration, and rebooting the Switch. In the explicit mode, the selection of QoS proÞles is Þxed and cannot be modiÞed because it is based only on priority.
SUMMIT.BK Page 3 Thursday, September 25, 1997 12:33 PM BUILDING BLOCKS PREDEFINED QOS PROFILES The following predeÞned QoS proÞles are provided, depending upon the QoS conÞguration of the Switch: ¥ Implicit QoS Mode Ñ A single QoS mode, called besteffort, is provided. It allows for 0% minimum and 100% maximum bandwidth along with a low-priority setting. Up to 15 other QoS proÞles may be deÞned. ¥ Explicit QoS Mode Ñ Four separate explicit QoS proÞles, each with varying priorities, are deÞned.
SUMMIT.BK Page 4 Thursday, September 25, 1997 12:33 PM QUALITY OF SERVICE (QOS) EXPLICIT TRAFFIC CLASSIFICATION Examples of trafÞc that have an explicit classiÞcation include tagged 802.1Q trafÞc that contains the deÞned 802.1p priority bits and other similar mechanisms (such as 3ComÕs PACEª). It can also be made explicit by virtue of which port in the Switch the trafÞc was sourced from. Explicitly deÞned trafÞc uses only priority in differentiating its QoS.
SUMMIT.BK Page 5 Thursday, September 25, 1997 12:33 PM CONFIGURING QOS CONFIGURING QOS Table 8-1 describes the commands used to conÞgure QoS. Table 8-1: QoS Configuration Commands Command Description create qosprofile Creates a QoS profile. The default values assigned to a created QoS profile are: ■ Minimum bandwidth — 0% ■ Maximum bandwidth — 100% ■ Priority — low config qosmode [explicit | implicit] Changes the QoS mode to explicit mode or implicit mode.

SUMMIT.BK Page 1 Thursday, September 25, 1997 12:33 PM 9 IP Unicast Routing The chapter describes how to conÞgure IP routing on the Summit. It assumes that you are already familiar with IP unicast routing.
SUMMIT.BK Page 2 Thursday, September 25, 1997 12:33 PM IP UNICAST ROUTING 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. In Figure 9-1, A Summit is depicted with two VLANs deÞned; Finance and Personnel. Ports 1 and 3 are assigned to Finance; ports 2 and 4 are assigned to Personnel. Finance belongs to the IP network 192.207.35.
SUMMIT.BK Page 3 Thursday, September 25, 1997 12:33 PM OVERVIEW OF IP UNICAST ROUTING DYNAMIC ROUTES Dynamic routes are typically learned by way of RIP. Routers that use RIP exchange information in their routing tables in the form of RIP advertisements. Using dynamic routes, the routing table contains only networks that are reachable. Dynamic routes are aged out of the table when a RIP update for the network is not received for a period of time.
SUMMIT.BK Page 4 Thursday, September 25, 1997 12:33 PM IP UNICAST ROUTING CONFIGURING IP UNICAST ROUTING This section describes the commands associated with conÞguring IP unicast routing on the Summit.
