Cooling Fans

Variable-speed cooling fans in the BayStack 350 switch provide cooling for the internal components. When you install the switch, be sure to allow enough space on both sides of the switch for adequate air flow.

Features

BayStack 350 switches provide wire-speed, 100BASE-TX/100BASE-FX (Fast Ethernet) switching that allows high-performance, low-cost connections to full-duplex and half-duplex 10 Mb/s and 100 Mb/s Ethernet local area networks (LANs).

Based on advanced application-specific integrated circuit (ASIC) technology, BayStack 350 switches can be cost effectively deployed in 10 Mb/s LANs.

BayStack 350 switches adjus t (auton egot iate) thei r port speed and duplex mode to match the best service provided by connected stations, up to 100 Mb/s in full-duplex mode. As per forman ce requ irements i ncrea se and 10 0 Mb/s LANs are deployed, each port uses autosensing to support any combination of 10 Mb/s and 100 Mb/s Ethernet LANs.

Security

Your BayStack 350 switch security feature can provide three levels of security for your local area network (LAN):

• MAC address-based security -- Limits access to the switch based on allowed source MAC addresses.

• RADIUS-based security -- Limi ts administrative ac ces s t o the switch through user authentication.

• SNMP security -- Limits administration access via IP filtering.

MAC Address- Based Security

The MAC address-based security feature allows you to set up network access control, based on source M AC addresses of authorized st ation s. You can specify a range of system responses to unauthorized access, which can range from sending a trap to disabling the intruder port. You can create a list of up to 98 MAC addresses and specif y which addres ses are auth orize d or not author ized to conne ct to the switch. You can also s pecif y which of the switc h po rts each MAC address is allowed to access. The options for allowed port access include: NONE, ALL, and single or multiple ports that are specified in a list, for example, 1-4, 6, 9, etc.

The MAC address -bas ed Secur ity fe ature is based on Nortel Netw or ks BaySecur e LAN Acces s for Ethernet, a real-ti me security system that safeguards Ethernet networks from unauthorized surveillance and intrusion. To learn more about the Nortel Networks BaySecure LAN Access for Ethernet, refer to the Bay Networks Guide to Implementing BaySecure LAN Access for Ethernet (Part number 345-1106A).

You must also include the MAC address of any router connected to any

Note:

secure ports.

893-00992-E

You can also specify optional actions to be exercise d by the switch if the softw ar e detects a securit y violatio n. The response can be to sen d a trap, turn on destinati on address (DA) filtering, disable the specif ic por t, or any combination of t hese three options. For instructions on using the console interface (CI) to set up network access control, see “MAC Address-Based Security” on page 3-26.

RADIUS-Based and SNMP Security

The RADIUS-based and SNMP security features allows you to set up network access control, using t he RADIUS (Remot e Authenti cation Dial-In User Service s) security protocol and selective IP filtering. The RADIUS-based security feature uses the RADIUS protocol to a uthentic ate TELNET logi ns. SNMP-based se curity limits administration access to the switch, based on IP address filters.

For instructions on using the console interface (CI) to set up the RADIUS-based Security feature, see “Network Security” on page 3-77.

For instructions on using the console interface (C I) to set up SNMP Se cur it y , see “TELNET Configuration” on page 3-68.

Using the BayStack 350 Series 10/100 Autosense Switch

Autosensing

BayStack 350 switches are autosensing and autonegotiating devices. The term autosense refers to a port’s ability to sense the speed of an attached device. The term autonegotiation refers to a standardized protocol (IEEE 802.3u) that exists between two IEEE 802.3u-capable devices. Autonegotiation allows the BayStack 350 switch to select the best of both speed and duplex modes.

Autosensing is use d whe n t he a tt ached device is not capable of autonegot iat i on or is using a form of autonegotiation that is not compatible with the IEEE 802.3u autonegotiation standard. In this case, because it is not possible to sense the duplex mode of the attached device, the BayStack 350 switch reverts to half-duplex mode.

When autonegotiation-capable devices are attached to the BayStack 350 switch, the switch ports ne gotiate do wn from 100 Mb/s spe ed and full-duple x mode until a supported speed and duplex mode is acknowledged by the attached device.

For more information about autosensing and autonegotiation modes, see “Autonegotiation Modes” on page 4-5.

MultiLink Trunking

The MultiLink Trunking feature allows a user to group multiple ports (up to four) together when forming a link to another switch or server, thus increasing aggregate thr oughput of the interconnection bet w een two devices, up to 8 00 Mb/ s in full-duplex mode. BayStack 350 switches can be configured with up to eight MultiLink Trunks.

The switch supports a load balancing function that allows the switch to spread traffic evenly across trunk members (ports that comprise a trunk), whenever possible, to achieve the highest aggregate throughput. In addition, the MultiLink Trunking software can detect misconfigured (or broken) trunk links. If this happens, the software redirects all traffic on the misconfigured or broken trunk member to other trunk members within that trunk.

The trunk members form a physical collection of ports that are treated as a single logical link of higher bandwidth by the spanning tree protocol (STP) and the learning, forwarding, and filtering functions.

For more information about the MultiLink Trunking feature, see “MultiLink

Trunks” on page 1-24.

1-10

893-00992-E

Port Mirroring

The Port Mirro ring feature (sometimes referred to as conversation steering) allows a user to designate a single switch port as a traffic monitor for up to two specified ports or two media access control (MAC) addresses.

You can specify port-based monitoring, where a ll traffic on specified ports is monitored, or address-based monitoring, where traffic between specified MAC addresses is monitored.

Getting Started

You can attach a probe device (such as a Nortel Networks StackProbe equivalent) to the designated monitor port. The designated port can monitor all traffic on the network segment connected to the mirrored port. Error packets can also be monitored and copied to the mirrored port for network troubleshooting.

For more information about the mirroring feature, see “Port Mirroring

(Conversation Steering)” on page 1-45.

Flash Memory Storage

The BayStack 350 switch uses flash memory to store the switch software image. Flash memory a llows you to update the software ima ge with a newer versio n without changing the switch hardware.

An in-band connection between the switch and the TFTP load host is required to download the software image (see “Software Download” on page 3-71).

For information about connecting a console terminal for this procedure, see “Console/Service Port Cabling” on page 3-2.

Note:

If a BootP server is set up properly on the network and the BayStack 350 switch detects a corrupted software image during the self-test, the switch automatically uses TFTP to download a new software image.

BootP Automatic IP Configuration

The BayStack 350 switch has a unique 48-bit hardwar e a ddr ess , or MAC address, that is printed on a label on the back panel. You use this MAC address when you configure the network BootP server to recognize the BayStack 350 switch BootP requests. A properly configured BootP server enables the switch to automatically learn its assigned IP address, su bnet mask, IP ad dress of t he default router (d efaul t gateway), and software image file name.

For an example of a BootP configuration file, see Appendix E, “Sample BootP Configuration Fil e.”

SNMP MIB Support

The BayStack 350 switch supports an SNMP agent with private MIB extensions, which ensur es compatibility with existing network management tools. The BayStack 350 switch supports MIB-II (RFC 1213) and the RMON MIB (RFC 1757), which pro vid e acces s to d etail ed manag ement st atis tics . With SNMP management, you can conf igu re SNMP t raps ( on ind i vid ual por ts) t o be gen erated automatically for cond itio ns such as an una uthor ized ac cess at temp t or chan ges in a port’s operating status.

Configuration and Switch Management

The BayStack 350 switch is shipped directly from the factory ready to operate in any 10BASE-T or 100BASE-TX standard network. You can manage the switch using the Nortel Networks Optivity

generic SNMP-based network management software; however, you must assign an IP address to the switch. You can set the switch’s IP address by using the console/service port or BootP, which resides on the switch.

For more informat ion abou t using the conso le/servi ce port t o conf igure the swit ch, see Chapter 3, “Using the Console Interface.”

Network Configuration

You can use BayStack 350 switches to connect workstations, personal computers (PCs), and serv ers to each oth er b y connecti ng these de vices d irectly to the switch, through a shared medi a hub that is conn ected to t he switch , or b y creat ing a virt ual LAN (VLAN) through the switch.

Power Workgroups and Shared Media Hub

Figure 1-6 shows power workgroups connected to servers through BayStack 350

switches in a small network. Network managers who do not want to provide each end station with the full 100 Mb/s bandwidth can designate a certain number of users that share the full bandwidth provided by one of the switch ports. For example, one workgroup is connected to a 10BASE-T shared media hub and shares 10 Mb/s bandwidth provided by one of the BayStack 350 switch ports.

VLAN Workgroups

You can create and configure VLANs by segmenting BayStack 350 switches into logical workgroups that are independent of each other. The workgroups can be defined according to project or department.

Workgroup members on VLANs share computer resources but cannot communicate with other workgroups; therefore access to specific servers is restricted to all but the assigned workgroup. Broadcast packets are also confined to a specific VLAN, which relieves traffic congestion (Figure 1-7

This same type of segmentation can be extended to multiple switches across the network. Because BayStack 350 Series switches implement port-based VLANs, extending VLANs to another switch requires utilizing a single switch port for each VLAN (Figure 1-8

Figure 1-8. VLANs spanning multiple switches

BayStack 350 switches a lso allow ports to exist in multiple VLA Ns for shared resources, such as servers, printers, and switch-to-switch connections.

1-17

Using the BayStack 350 Series 10/100 Autosense Switch

There are limitations when configuring multiple VLANs on a port and when configuring VLA Ns that cross multiple swit ches. For example, to have multiple VLANs that span multiple swit ches, no port sh ould be c onf igur ed to e xi st in mor e than one VLAN in any of the switches. This method partitions the switches into different, non-overlapping VLANs as shown previously in Figure 1-8

It is also possible to have resources exist in multiple VLANs on one switch as shown in Figure 1-9

. In this example, clients on dif ferent broadca st domains share resources. The br oad cas ts f rom por ts co nfigured in VLAN V1+V2 can be seen by both VLAN V1 and VLAN V2 ports. Broadcasts from VLAN V1 ports can only be seen by other VLAN V1 ports or VLAN V1+V2 ports. This analogy is also true for ports that are assigned to VLAN V2.

Switch SW1 can connect to switch SW2 because all of the ports on switch SW2 are configured in a single VLAN (VLAN V1). The same is true for switch SW3 where all of the ports are configured in a single VLAN (VLAN V2). In both of these cases, the connection port from switch SW1 matches the configuration of the other switch. The con necti on to swi tch SW 4 is al so v al id bec ause, i n this case, there is no longer a distinction between VLANs V1 and V2. VLAN V1+V2 is, in effect, a single VLAN that contains both broadcast domains.

Additional Tips About Configuring VLANs

To group switch ports into logical workgroups, select the ports under the VLAN

name (V1, V2, ....., or V8) in the VLAN Configuration screen. If you want users

on different VLANs to share a port, select that port under each VLAN name. You can create VLANs for one BayStack 350 switch, or you can create VLANs

that span multiple switches. However, each switch that participates i n the VLAN configuration must be configured individually. You can also assign multiple VLANs to a port connected to a server, which allows the server to be shared by multiple logical workgroups.

You can only create five VLANs when the MultiLink Trunking feature is active. The VLAN Configuration screen displays five VLAN columns when any trunk is enabled.

893-00992-E

Using the BayStack 350 Series 10/100 Autosense Switch

MultiLink Trunks

BayStack 350 switches support two types of trunking configurations:

• Inter-switch trunk configuration

• Server trunk configuration You can choose the configuration type from the MultiLink Trunk Configuration

Menu screen (see “MultiLink Trunk Configuration” on page 3-39). Inter-switch trunk configurations are designated as (trunks) I1 to I4 in the

Inter-Switch Trunk Configuration screen. Server trunk configurations are designated as (trunks) S1 to S4 in the Server Trunk Configuration screen.

This trunk designation convention is also used in related screens that display trunking information (for example, the VLAN Configuration screen).

Any combination of each configuration type (server trunk and inter-switch), can be used to configure up to 16 trunk members on each switch).

Inter-Switch Trunk Configuration

1-24

You can use the Inter-Switch Trunk Configuration screen to create switch-to-switch trunk links. This configuration type allows you to logically connect up to eight switch ports together to form up to four trunks in any of the following configurations:

• One trunk -- With the trunk configured with at least two trunk members, but

not more than fo ur.

• Two trunks -- With each trunk configured with at least two trunk members,

but not more than four.

• Three trunks -- W i th each t runk configured with at least two trunk member s,

but not more than four; the combined trunks cannot exceed eight trunk members (see Note).

Note:

When you create a three trunk configuration, do not configure any two of the trunks with three trunk members. That configuration is not supported.

• Four trunks -- With each trunk configured with two trunk members.

893-00992-E

Getting Started

You can configure individual trunks between multiple switches as shown in

Figure 1-15

Although Figure 1-15

shows only two inter-switch trunks (I1 and I2) connecting switch SW1 to switches SW2 and SW3, you can configure any BayStack 350 switch with up to four inter-switch trunks.

You can configure MultiLink trunks with up to four switch ports to provide up to 800 Mb/s aggregate bandwidth through each trunk, in full-duplex mode. As shown in Figure 1-15

, when traffic between switch-to-switch connections approaches single port bandwidth limitations, creating a MultiLink trunk can supply the additional bandwidth required to improve the performance.

• Four trunks -- With each trunk configured with two trunk members.

When you use the Server T runk Conf ig uration scr een to connect a trunk

Note:

to a server that uses a single MAC address, set up your trunk members according to the information provided in Appendix B, “Server/Trunk Connections.”

893-00992-E

Getting Started

Figure 1-16 shows a typical server trunk topology utilizing the server trunk

configurat ion. FS1 ut ili zes du al MAC addresses, usin g one MAC address for each NIC. For this reason, FS1 does not require a trunk assignment. FS2 is a single MAC server (with a four-port NIC) and is set up as a server trunk configuration (S1).

In this configuration example, server trunk S1 is assigned trunk members that correspond to the information provided in Appendix B, “Server/Trunk Connections.” This allows the trunks to operate at optimal efficiency.

Client/Server Configuration Utilizing MultiLink Trunks

Figure 1-17

shows an example of how MultiLink trunking can be used in a

client/server configuration. In this example, both servers are connected directly to switch SW1. FS2 is

connected through a server trunk configuration (S1). The switch-to-switch connections are through inter-switch trunks (I1, I2, I3, and I4).

893-00992-E

1-27

Using the BayStack 350 Series 10/100 Autosense Switch

Clients accessing data from the servers (FS1 and FS2) are provided with maximized bandwidth through server trunk S1 and inter-switch trunks I1, I2, I3, and I4. Trunk members (the ports making up each trunk) do not have to be consecutive switch ports; they can be selected randomly, as shown by I4.

With spanning tree enabled, one of the trunks (I1 or I2) acts as a redundant (backup) trunk to s witch S W2. With spanning tr ee disabled, trunks I1 and I 2 must be configured into separate VLANs for this configuration to function properly (see “VLAN Workgroups

Before Configuring Trunks

When you create and enable a trunk, the trunk members (switch ports) take on certain setti ngs nece ssary for co rr ect op erati on of t he Mul tiLi nk Trunking feature. These settings, along wi th s pec ific configurati on r ules, must be considered before configuring your MultiLink trunk.

Before configuring any MultiLink trunk, follow these steps:

Read the configuration rules provided in the next section, “MultiLink

Trunking Configuration Rules.”

Determine which switch ports (up to 4) are to become trunk members (the specific ports making up the trunk). Be sure that:

At least two ports (minimum) are configured for each trunk.

The chosen switch ports are set to Enabled, using th e Port Configuration screen (see “Port Configuration” on page 3-36) or through network management.

1-40

The trunk member ports are in the same VLAN.

Ensure that all netw ork cabling is complete and stable bef o re configuring any trunks, to avoid misconfiguration errors.

Consider how the existing spanning tree will react to the new trunk configuration (see “Spanning Tree Considerations

Consider how existing VLANs wil l be affec ted by th e additi on of a t runk;

MultiLink Trunking Configuration Rules

The MultiLink Trunking feature is deterministic; that is, it operates according to specific configuration rules. When creating trunks, consider the following rules that determine how the MultiLink trunk reacts in any network topology:

Any port that part icipate s in MultiLi nk T run king must be an acti v e port (se t to Enabled via the Port Configuration screen or through network management).

All trunk members must be configured into the same VLAN before the T run k Configuration screen’s Trunk Status field can be set to Enabled (See “VLAN Configuration” on page 3-34).

When an acti v e port is co nfi gured i n a t runk, th e port becomes a trunk member as soon as the Trunk Status f ield i s set to Ena bled. Af ter the Trunk Status field is set to Enab led, the spanning tree par ameters for the port will change to reflect the new tru nk settings.

If spanning tree participation of any trunk member is changed (enabled or disabled), the spanning tree participation of all members of that trunk is changed similarly (see “Spanning Tree Considerations

When a trunk is enabled, the trunk spanning tree participation setting takes

” on page 1-42).

precedence over that of any trunk member. When a trunk is active, the trunk STP setting can be changed fr om ei the r t he I nter-Switch Trunk Configuration screen or the Spanning Tree Configuration screen.

893-00992-E

Only five VLANs are allowed when MultiLink Trunking is active.

If the VLAN settings of an y trunk member are cha nged, the VLAN settings of all members of that trunk are changed similarly.

When any trunk member is set to Disabled (not active) through the Port Configuration screen or through network management, the trunk member is removed from the trunk. A screen prompt precedes this action.

A removed trunk member does not rejoin the trunk if it is then reset to

Note:

Enabled. The remov ed tr unk member has to be reconf igure d through the Trunk Configuration screen to rejoin the trunk.

A trunk member cannot be configured as a monitor port (see “Port Mirroring Configuration” on page 3-48).

Trunks cannot be monitored by a monitor port; however, trunk members can be monitored (see “Port-Based Mirroring Configuration

” on page 1-46).

Spanning Tree Considerations

The spanning tree Path Cost parameter is recalculated based on the aggregate bandwidth of the trunk. For example, Figure 1-27 trunk (I1) with two port members operating at 100 Mb/s and the other two port members operating at 10 Mb/s. Trunk I1 provides an aggregate bandwidth of 220 Mb/s. The Path Cost for I1 is 4 (Path Cost = 1000/LAN speed, in Mb/s). If a second three port trunk (I2) is configured with an aggregate bandwidth of 210 Mb/s, with a comparable Path Cost of 4, the switch software chooses the trunk with the larger bandwidth (I1) to determine the most efficient path.

The trunk is also viewed by management stations as a single spanning tree port. The spanning tree port is represented by the trunk member with the lowest port number. For example, if ports 13, 14, 15, and 16 are trunk members of Trunk I1, the management station views Trunk I1 as spanning tree port 13.

Additional Tips About the MultiLink Trunking Feature

When you create a MultiLink Trunk, the individual trunk members (the specific ports comprising the trunk) are logi cally connect ed and react as a si ngle entity. For example, if you change spanning tree parameters for any trunk member, the spanning tree parameters for all trunk members are changed.

All configured trunks are indicated in the Spanning Tree Configuration screen. The screen’s Trunk field lists the active trunks, adjacent to the port numbers that correspond to the specific trunk member for that trunk.

When a trunk is active you can di sable spann ing tre e part icip ation us ing t he Trunk Configuration screen or using the Spanning Tree Configuration screen.

When a trunk is not active, the spanning tree participation setting in the Trunk Configuration screen does not take effect until the Trunk Status field is set to Enabled.

When MultiLink Trunking is active, all VLAN screens change to show only five VLANs available for configuration. VLAN columns V6 to V8 are not displayed. Also, if more than five VLANs are configured and you try to enable a MultiLink trunk, the trunk configuration screen prompts you to reconfigure VLANs V6 through V8.

Port Mirroring (Conversation Steering)

You can designate one of your switch por ts to moni tor t raffic on an y two spe cif i ed switch ports (port-based) or to monitor traffic to or from any two specified addresses that the switch has learned (address-based).

A probe device, such as the Nortel Networks StackProbe or equivalent,

Note:

must be connected to the designated monitor port to use this feature (contact your Nortel Networks sales agent for details about the StackProbe).

• Address-b ased Mirroring A sample of the Port Mirroring Configuration screen is provided with each of the

examples to support the network configuration example. Note that in the following examples, the displayed screens do not show all of the

screen prompts that precede some actions. For example, when you configure a switch for port mirroring or when you modify an existing port mirroring configuration, the new configuration does not take effect until you respond [Yes] to the following screen prompt:

Is your port mirroring configurat ion complete? [ Yes ]

Getting Started

Port Mirroring Configuration Rules

The following configuration rules must be applied to any port mirroring configuration:

A monitor port cannot be configured as a trunk member.

When a port is configured and enabled as a monitor port, the port is automatically disabled from participating in the spanning tree. When the port is reconfigured as a standard switch port (no longer a monitor port), the port becomes enabled for spanning tree participation.

When creating a port-based port mirroring configuration, be sure that the monitor port and both o f t he mirrored ports, port X and port Y, are configured on the same VLAN. Use the VLAN Configuration screen to configure the VLAN (see “VLAN Configuration” on page 3-34).

VLAN configuration settings for any ports configured for port-based mirroring cannot be changed. Use the Port Mirroring Configuration screen to disable port mirroring (or reconfigure the port mirroring ports), then change the VLAN configuration settings. See also Step 3.
