The Console port allows you to access the console interface (CI) screens and customize your network using the supplied menus and screens (see Chapter 3,

“Using the console interface,” on page 93).

212859-A

Chapter 1 BayStack 380 Switch 27

The Console port is a DB-9, RS-232-D male serial port connector. You can use this connector to connect a management station or console/terminal to the BayStack 380 Switch by using a straight-through DB-9 to DB-9 standard serial port cable. You must use a VT100/ANSI-compatible terminal (for cursor control and to enable cur so r and functi ons k e ys) to use t he cons ole po rt. Se e I nstalli ng the BayStack 380 10/100/1000 Switch for more information.

Note: The console port is configured as a data communications equipment (DCE) connector. Ensure that your RS-232 cable pinouts are configured for DCE connections (see Appendix D, “Connectors and pin

assignments,” on page 201).

The Console port defau lt setti ngs are: 9600 baud wit h eight da ta bit s, one stop bi t, and no parity as the com municati ons format, with flow cont rol set to ena bled.

Small Form Factor Pluggable (SFP) Gigabit Interface Converter

Small Form Factor Pluggable Gigabit Interface Converters are hot-swappable input/output enhancement components designed for use with Nortel Networks products to allow Gigabit Ethernet ports to link with Short Wavelength (SX), Long Wave length (LX), and Coarse Wavelength Division Multiplexed (CWDM) fiber optic networks.

Port connectors

The BayStack 380 Swit ch uses 10/ 100/1000B ASE-TX RJ-45 (8-pin modula r) port connectors.

The 10/100/1000BASE-TX port connectors feature auto-MDI-X (media-dependen t interf a ce-cross o v er). Thes e ports conn ect o v er st raight -through cables to the network interface card (NIC) in a node or server, similar to a conventional Ethernet repeater hub. However, with this feature and auto-negotiation enabled, you can still use straight-through cables while connecting to an Ethernet hub or switch.

For details on pin assignments and for directions on how to make your own cross-over cables, see “Appendix D, “Connectors and pin assignments,” on page

201).

28 Chapter 1 BayStack 380 Switch

The BayStack 380 Switch uses autosensing ports designed to operate at 10 Mb/s (megabits per second), 100 Mb/s, OR 1000 Mb/s (1 gigabit) depending on the connecting dev ic e. These por ts supp ort the IEEE 802.3u, 802.3z for 1000SS, or

802.3ab for 1000TX autonegotiation standard, which means that when a port is connected to another device that also supports the IEEE 802.3u, 802.3z for 1000SS, or 802.3ab for 1000TX s tandard, the two de vices ne gotia te the b est spee d and duplex mode.

The BayStack 380 Switch features auto-polarity. With autonegotiation enabled, auto-polarity automatically reverses the polarity of a pair of pins from positive to negative or negative to positive. This corrects th e polarity o f the received data if the port detect s tha t the pol arit y of t he dat a has been r e v er sed due to a wir ing er ror.

The 10/100/1000BASE-TX switch ports also support half- and full-duplex mode operation at 10 Mb/s and 100 Mb/s (refer to Installing the BayStack 380 10/100/ 1000 Switch).

The 10/100/1000BASE-TX RJ-45 ports can connect to 10 Mb/s or 100 Mb/s or 1000 Mb/s (1 gigabit) Ethernet segments or nodes.

Note: Use only Category 5 copper unshielded twisted pair (UTP) cable connections when connecting 10/100/1000BASE-TX ports.

Note: IEEE 1000BASE- TX require s operati ng in ful l-duple x mode wi th auto-negot i ati on enabled.

Features

The BayStack 380 Switch provides wire-speed switching that allows high-performance, low-cost connections to full-duplex and half-duplex 10/100/1000 Mb/s Ethernet local area networks (LANs). The BayStack 380 Switch provides the following features.

212859-A

Chapter 1 BayStack 380 Switch 37

Virtual Local Area Networks (VLANs)

In a traditional shared-media network, traffic generated by a station is transmitted to all other stations on the local segment. Therefore, for any given station on the shared Ethernet, the local segment is the collision domain because traffic on the segment has the potential to cause an Ethernet collision. The local segment is also the broadcast domain because any broadcast is sent to all stations on the local segment. Although Ethernet switches and bridges divide a network into smaller collision domains, they do not affect the broadcast domain. In simple terms, a virtual local area network provides a mechanism to fine-tune broadcast domains.

Your BayStack 380 Switch allows you to create port-based VLANs:

• IEEE 802.1Q port-based VLANs

A port-based VLAN is a VLAN in whic h the por ts are expli citly c onf igured t o be in the VLAN. When you create a port-based VLAN, you assign a Port VLAN Identifier (PVID) and specify which ports belong to the VLAN. The PVID is us ed to coord inate VLAN s across multiple switches.

• Auto PVID

Security

The BayStack 380 Swi tch s ecurity fea tures pr o vide two levels of security for your local area network (LAN):

• RADIUS-based security—limits administrative access to the switch through

• MAC address-based security—limits access to the switch based on allowed

Figure 5 shows a typical campus configuration using the BayStack 380 Switch

security features. This example assumes that the switch, the teachers’ offices and classrooms, and the li brary are phy sical ly secured . The stude nt do rmitory may ( or may not be) physically secure.

When Auto PVID is active, a port that is assigned to a numbered VLAN has the same number for its PVID. For exa mple, if the VLAN is 2, the PVID is 2.

Chapter 1 BayStack 380 Switch 39

In this configuration example, the following security measures are implemented:

•The switch

— RADIUS-based security is used to limit administrative access to the

switch through user authentication (see “RADIUS-based network

security” on page 40).

— MAC address-based security is used to allow up to 448 authorized

stations (MAC addresses) access to one or more switch ports (see “MAC address-based security” on page 40).

— The switch is located in a locked closet, accessible only by authorized

Technical Services personnel.

• Student dormitory

Dormitory rooms are typically occupied by two students and have been prewired with two RJ-45 jacks. Only students who are authorized (as specified by th e MAC address-based secur ity feature) can access the swit ch on the secured ports.

• Teachers’ offices and classrooms

The PCs that are located in the teachers’ offices and in the classrooms are assigned MAC address-based security that is specific for each classroom and office location. The security feature logically locks each wall jack to the specified station and prevents unauthorized access to the switch should someone attempt to connect a personal laptop PC into the wall jack. The printer is assigned as a single station and is allowed full bandwidth on that switch port.

It is assumed that all PCs are password protected and that the classrooms and offices are physically secured.

• Library

RADIUS-based network security

The RADIUS-based security feature allows you to set up network access control, using the RADIUS (Remote Authentication Dial-In User Services) security protocol. The RADIUS-based security feature uses the RADIUS protocol to authenticate local console and Telnet logins.

You will need to set up specific user accounts (user names and passwords, and Service-Type attributes) on your RADIUS server before the authentication process can be initiated. To provide each user with appropriate levels of access to the switch, set the following username attributes on your RADIUS server:

• Read-write access—Set the Service-Type field value to Administrative.

• Read-only access—Set the Service-Type field value to NAS-Prompt.

For detailed instructions to set up your RADIUS server, refer to your RADIUS server documentation.

For instructions to use the console interface (CI) to set up the RADIUS-based security feature, see Chapter 3, “Using the console interface,” on page 93.

MAC address-based security

The MAC address-based security feature allows you to set up network access control, based on source MAC addresses of authorized stations.

You can:

• Create a list of up to 448 MAC addresses and specify which addresses are

authorized to connect to your switch configuration. The 448 MAC addresses can be configured within a single standalone switch.

• Specify which of your switch ports each MAC address is allowed to access.

The options for allowed port access include: NONE, ALL, and a single port.

The MAC address-based security feature is based on Nortel Networks BaySecure LAN Access for Ethernet, a real-time security system that safeguards Ethe rnet networks from unauthorized surveillance and intrusion.

For instructions to use the console interface (CI) to set up the RADIUS-based security feature, see Chapter 3, “Using the console interface,” on page 93.

Flash memory storage

Switch software im age storage

The BaySt ack 380 Switch uses flash memory to store the switch software image. The flash memory allows you to update the softwa re image with a newer version without changing the switch hardware (see “Software Download screen” on

page 164). An in-band connection between the switch and the TFTP load host is

required to download the s oftware image.

Configuration parameters storage

All configuration parameters are stored in flash memory. These parameters are updated every 60 seconds (if a change occurs) or whenever a reset command is executed.

Chapter 1 BayStack 380 Switch 41

Warning: Do not power off the switch within 10 seconds of changing

any configuration parameters. Powering down the switch within 10 seconds of changing configuration parameters can cause the changed configuration parameters to be lost.

MultiLink Trunking

The MultiLink Trunking feature allows you to group multiple ports, two to four together, when forming a link to another switch or server, thus increasing aggregate throughput of the interconnection between two devices, up to 8 Gb/s in full-duplex mode. The BayStack 380 Switch can be configured with up to six MultiLink Trunks.

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

Trunk Configuration Menu screen” on page 136.

Po rt mirroring (conversation steering)

The port mirroring feature (sometimes referred to as conversation steering) allows you to designate a single switch port as a traffic monitor for a specified port. You can specif y port-based monitoring for ingress and egress at a specific port. You can also attach a probe device (such as a Nortel Networks StackProbe, or equivalent) to the designated monitor port.

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

Configuration screen” on page 142.

Autosensing, autonegotiation, auto-MDI/X, and autopolarity

The BayStack 380 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 or

802.3z or 802.3ab) that exists between two IEEE -capable devices. Autonegotiation allows the switch to select the best of both speed and duplex modes.

• The term autopolarity refers to automatic detection of transmit and receive

twisted pairs.

Autosensing is used when the attac hed device is not capable of autone gotiation or is using a form of autonegotiation that is not compatible with the IEEE 802.3z autonegotiation standard. In this case, because it is not possible to sense the duplex mode of the attached device, the BayStack 380 Switch reverts to half-duplex mode.

When autonegotiation-capable devices are attached to the BayStack 380 Switch, the ports negotiate down from 1000 Mb/s speed and full-duplex mode until the attached device acknowledges a supported speed and duplex mode.

Auto-MDI-X detects receive and transmit twisted pairs automatically. When auto-MDI-X is active, any straight or crossover category 5 cable can be used to provide connection to a port. If autonegotiation is disabled, then auto-polarity is not active.

BootP automatic IP configuration/MAC address

The BayStack 380 Switch has a unique 48-bit hardware address, or MA C addr ess, 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 380 Switch BootP requests. A properly configured BootP server enables the switch to automatically learn its assigned I P address, su bnet mask , IP address of the defa ult route r (def ault gateway), and software ima ge file name.

Using the BayStack 380 10/100/1000 Switch

46 Chapter 1 BayStack 380 Switch

The BootP Request Mode field in the IP Configuration screen allows you to choose which method the switch uses to broadcast BootP requests:

• BootP When Needed

• BootP Always

• BootP Disabled

• BootP or Last Address

Note: Whenever the switch is broadcasting BootP requests, the BootP process will eventually time out if a reply is not received. When the process times out, the BootP request mode automatically changes to BootP Disabled mode. To restart the BootP process, change the BootP request mode to any of the three following modes:

• BootP When Needed

• BootP Always

•

BootP or Last Address

Configuration and switch management

The BayStack 380 Switch is shipped directly from the factory ready to operate in any 10BASE-T, 100BASE-TX, or 1000BASE-TX standard network.

You must assign an IP address to the switch, depending on the mode of operation. You can set both addresses by using the console port or BootP, which resides on the switch. You can manage the switch using:

• Console interface The console interface allows you to configure and manage the switch locally

or remotely. Access the CI menus and screens locally through a console terminal attached to your BayStack 380 Switch, remotely through a dial-up modem connection, or in-band through a Telnet session.

IEEE 802.1Q VLAN workgroups

BayStack 380 switches support up to 64 port-based VLANs with IEEE 802.1Q tagging available per p ort . Por ts are grou ped i nt o broadcast domains by assi gni ng them to the same VLAN. Frames received in one VLAN can only be forwarded within that VLAN, and multi ca st fr ames and unknown unicast f rames are flooded only to ports in the same VLAN.

Setting up virtual LANs (VLANs) is a way to segment networks to increase network capacity and performance without changing the physical network topology (Figure 10). With network segmentation, each switch port connects to a segment that is a si ngle broadcast domain . When a switch port is con fi gur ed t o be a member of a VLAN, it is added to a group of ports (workgroup) that belong to one broadcast domain.

The BayStack 380 Switch allows you to assi gn ports to VLANs u sing the con sole, Telnet, Web-based management, or an appropriate SNMP-based application. You can assign different ports (and therefore the devices attached to these ports) to different broadcast domains. This feature allows network flexibility because you can reassign VLANs to accommodate network moves, additions, and changes, eliminating the need to change physical cabling.

IEEE 802.1Q tagging

BayStack 380 switches operate in accordance with the IEEE 802.1Q tagging rules. Important terms used with the 802.1Q tagging feature are:

• VLAN identifier (VID)—the 12 -bit portion of the VLAN tag in th e frame header that identifies an explic it VLAN. Wh en other types of VLAN s are enabled, this default value can be overridden by the values enabled in the Web-based management interface. Refer to Using Web-Based Management for the BayStack 380 10/100/1000 Switch.

• Port VLAN identif i er (PVID)—a classification mechanism tha t associates a port with a specific VLAN. For example, a port with a PVID of 3 (PVID =3) assigns all untagged frames received on this port to VLAN 3.

• Tagged frame— the 32-bit field (VLAN tag) in the frame header that identifies the frame as belonging to a specific VLAN. Untagged frames are marked (tagged) with this classification as they leave the switch through a port that is configured as a tagged port.

• Untagged frame— a frame th at does not carr y any VLAN tagging infor mation in the frame header.

• VLAN port members— a set of ports that form a broadcast domain for a specific VLAN. A port can be a member of one or more VLANs.

• Untagged member—a port that has been configured as an untagged member of a specific VLAN. When an untagged frame exits the switch through an untagged member port, the frame header remains unchanged. When a tagged frame exits the switch through an untagged member port, the tag is stripped and the tagged frame is changed to an untagged frame.

• Tagged member—a port that has been configured as a member of a specific VLAN. When an untagged frame exits the switch through a tagged member port, the frame header is modified to include the 32-bit tag associated with the PVID. When a tagged frame exits the switch through a tagged member port, the frame header rema ins unchanged (origi nal VID remains).

• User priority—a three-bit field in the header of a tagged frame. The field is interpreted as a b inary number, therefore has a value of 0 - 7. This f ield allows the tagged frame to carry the user-priority across bridged LANs where the individual LAN segments may be unable to signal priority information.

• Port priority—the priority level assigned to untagged frames received on a port. This value becomes the user priority for the frame. Tagged packets get their user priority from the value contained in the 802.1Q frame header.

212859-A

Chapter 2 Network configuration 57

• Unregistered pac ket—a tagge d frame that cont ains a VID whe re th e rec eiving port is not a member of that VLAN.

The default configuration settings for BayStack 380 switches have all ports set as untagged members of VLAN 1 with all ports configured as PVID = 1. Every VLAN is assigned a unique VLAN identifier (VID) that distinguishes it from all other VLANs. In the default configuration example shown in Figure 11, all incoming packets are assigned to VLAN 1 by the default port VLAN identifier (PVID =1). Untagged packets enter and leave the switch unchanged.

VLANs spanning multiple switches

You can use VLANs to segment a network within a switch. When you connect multiple switches, it is possible to connect users of one VLAN with users of that same VLAN in another switch. However, the configuration guidelines depend on whether both switches support 802.1Q tagging.

With 802.1Q tagging enabled on a port for a VLAN, all frames leaving the port for that VLAN are marked as belonging to that specific VLAN. You can assign specific switch ports as members of one or more VLANs that span multiple switches, without interfering with the Spanning Tree Pro tocol.

VLANs spanning multiple 802.1Q tagged switches

Figure 16 shows VLANs spanning two BayStack 380 switches. The 802.1Q

tagging is enable d on S1, por t 2 and on S2, po rt 1 fo r VLAN 1 and VLAN 2. Bot h ports are tagged members of VLAN 1 and VLAN 2.

Chapter 2 Network configuration 61

Because there is only one link between the two switches, the Spanning Tree Protocol (STP) trea ts this configu rati on as any other s wit ch- to- swi tc h c onnection. For this configuration to work properly, both switches must support the 802.1Q tagging protocol.

VLANS spanning multiple untagged switches

Figure 17 shows VLANs spanning multiple untagged switches. In this

configuration, Switch S2 does not support 802.1Q tagging and you must use a single switch port on each switch for each VLAN.

For this configuration to work properly, you must set spanning tree participation to Disabled (the STP is not supported across multiple LANs).

When the STP is enabled on these switches, only one link between each pair of switches will be for w ar din g t raffic. Bec aus e each port belongs t o only one VLAN at a time, connectivit y on the othe r VLAN is lost. Exe rcise care when conf igur ing the switches to ensure that the VLAN configuration does not conflict with spanning tree configuration.

To connect multiple VLANs across switches with redundant links, you must disable the STP on all participating switch ports. Figure 18 shows possible consequences of enabling the STP when using VLANs between untagged (non-802.1Q tagged) switches.

As shown in Figure 18, with STP enabled, only one connection between Switch S1 and Switch S2 is forwarding at any time. Communications failure occurs between VLAN 2 of S1 and VLAN 2 of S2, blocking communications between Stations A and B.

The STP selects the link connecting VLAN 1 on Switches S1 and S2 as the forwarding link based on port speed, duplex-mode, and port priority. Because the other link connecting VLAN 2 is in Blocking mode, stations on VLAN 2 in Switch S1 cannot communicate with stations in VLAN 2 on Switch S2. With multiple links only on e link will b e forwardi ng.

BayStack 380 switches allow ports to exist in multiple VLANs for shared resources, such as servers, printers, and switch-to-switch connections. It is also possible to have resources exist in multiple VLANs on one switch as shown in

Figure 19.

In this example, clients on different broadcast domains share resources. The broadcasts from ports configured in VLAN 3 can be seen by all VLAN port members of VLAN 3.

For example, to create a broadcast domain for each VLAN shown in Figure 20, configure each VLAN with a po rt membershi p, and each por t with the a ppropriat e PVID/VLAN association:

• Ports 8, 6, and 11 are untagged members of VLAN 1.

• The PVID/VLAN association for ports 6 and 11 is: PVID = 1.

• Ports 2, 4, 10, and 8 are untagged members of VLAN 2.

• The PVID/VLAN association for ports 2, 4, and 10 is: PVID = 2.

• Ports 2, 4, 10, 8, 6, and 11 are untagged members of VLAN 3.

• The PVID/VLAN association for port 8 is: PVID = 3.

The following steps show how to use the VLAN configuration screens to configure the VLAN 3 broadcast domain shown in Figure 20.

VLAN workgroup summary

This section summarizes the VLAN workgroup examples discussed in the previous sections of this chapter.

As shown in Figure 25, Switch S1 (BayStack 380 Switch) is configured with multiple VLANs:

• Ports 1, 6, 11, and 12 are in VLAN 1.

• Ports 2, 3, 4, 7, and 10 are in VLAN 2.

• Port 8 is in VLAN 3.

Because S4 does not support 802.1Q tagging, a single switch port on each switch must be used for each VLAN (see “VLANS spanning multiple untagged

switches” on page 61).

The connection to S2 requires only one link between the switches because S1 and S2 are both BayStack 380 switches that support 802.1Q tagging (see “VLANs

spanning multiple 802.1 Q tag ged swit ch es” on page 60).

VLAN configuration rules

VLANs operate accor ding to spec ific conf igurat ion rules . Whe n cre ating VLANs, consider the following rules that determine how the configured VLAN react s in any network topology:

• All ports that are involved in port mirroring must have memberships in the same VLANs. If a port is configured for port mirroring, the port’s VLAN membership cannot be changed.

• If a port is a trunk group member, all trunk members are added or deleted from the VLAN.

• All ports involved in trunking and port mirroring must have the same VLAN configuration. If a port is on a trunk with a mirroring port, the VLAN configuration cannot be changed.

• Auto PVID can be acti vated by c reating a VLAN and enabl ing Auto PVI D for it.

Independent VLANs (IVL)

You can configure a VLAN as an Independent VLAN (IVL). Each independent VLAN maintains its own MAC Address table.

Independent VLANs can h ave dupl ic ate MAC Addr es ses on di fferent VLANs. In

Table 7, both VLANs use the duplicate MAC Address “A”.

IEEE 802.1p Prioritizing

You can use the VLAN Configuration screens to prioritize the order in which the switch forwards packets, on a per-port basis. For example, if messages from a specific segment are crucial to your operation, you can set the switch port connected to that se gment to a higher prio rity l evel (by default , all switch ports a re set to Low priority). When the switch receives untagged packets on that port, the untagged packets are tagged according to the priority level that you assign to the port.

As shown in Figure 27, the switch provides four transmission queues, Highest, High, Low, and Lowest for any given port. Frames are assigned to one of these

queues on the basis of the user_priority value, using a traffic class table. This table is managed by using the Traffic Class Configuration screen. The table indicates the tr affic class ass ign ed to the frame for each user_priority val ue. If the frame leaves the switch formatted as a tagged packet, the traffic clas s assigned to the frame is carried forward to the next 802.1 p-capable switch. Thi s allows the packet to carry the as signed traffic class priority through the network until it reaches its destination.

The following steps show how to use the Traffic Class Configuration screen to configure the port priority level.

212859-A

Chapter 2 Network configuration 73

To configure the priority level, follo w these steps:

1 Determine the priority level you want to assign to the switch port.

User priority levels are assigned default settings in all BayStack 380 switches. The range is from 0 t o 7. The traf fi c class t able can be modi fied. You can view the settin gs shown i n the Traffic Class configuration screen, and then set the port priority in the VL AN Port Configuration screen.

MultiLink Trunks

MultiLink Trunks allow you to group from two to four switch ports together to form a link to another switch or server, thus increasing aggregate throughput of the interconnection between the devices (up to 8 Gb/s in full-duplex mode). You can configure up to six MultiLink Trunks. The trunk members can only reside on a single unit. MultiLink Trunking software detects misconfigured (or broken) trunk links and r edi rects traf fi c on the misconfigured or br oke n trunk link to ot her trunk members within that trunk. If there is only a single trunk, the trunk can be blocked and no traffic will get through.

You can use the Trunk Configuration screen to create switch-to-switch and switch-to-server MultiLink Trunk links (Figure 30 and Figure 31).

212859-A

Chapter 2 Network configuration 75

You can configure each of the trunks shown in Figure 30 with up to four switch ports to provide up to 8 Gb/s aggregate bandwidth through each trunk, in full-duplex mode. As shown in this example, 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.

Figure 31 shows a typical switch-to-server trunk configuration. In this example,

file server FS1 uses dual MAC addresses, using one MAC address for each network interface card (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 trunk configuration T1.

Client/server configuration using MultiLink Trunks

Figure 32 shows an example of how MultiLink Trunking can be used in a

client/server configuration. In this example, both servers connect directly to Switch S1. FS2 is connected through a trunk configuration (T1). The switch-to-switch connections are through trunks (T2, T3, T4, and T5).

10486EA

212859-A

Clients accessing data from the servers (FS1 and FS2) are provided with maximized bandwidth through trunks T1, T2, T3, T4, and T5. Trunk members (the ports making up each trunk) do not have to be consecutive switch ports; you can select ports randomly, as shown by T5.

With spanning tree enabled, one of the trunks (T2 or T3) acts as a redundant (backup) trunk to Switch S2. With spanning tree disabled, you must configure trunks T2 and T3 into separate VLANs for this configuration t o f unct i on pr ope rl y Refer to “IEEE 802.1Q VLAN workgroups” on page 55 for more information.

Before you configure trunks

When you create and enable a trunk, the trunk members (switch ports) take on certain setti ngs nec ess ary fo r corr ec t oper ation of the Mult iLink Trunking feature.

Before you configure your MultiLink Trunk, you must consider these settings, along with specific configuration rules, as follows:

1 Read the configuration rules provided in the next section, “Spanning tree

considerations for MultiLink Trunks” on page 87.

2 Determine which switch ports (up to four) are to become trunk members (the

specific ports making up the trunk). A minimum of two ports are required for each trunk.

Ensure that the chosen switch ports are set t o Enabled, using either the Port Configuration scree n (see “Port Configuration screen” on page 131) or network management.

Trunk member ports must have the same VLAN configuration.

3 All network cabling should be complete and stable before configuring any

trunks, to avoid configuration errors.

4 Consider how the existing spanning tree will react to the new trunk

configuration (see “Spanning tree considerations for MultiLink Trunks” on

page 87).

5 Consider how existing VLANs will be affected by the addition of a trunk. 6 After completing the above steps, see “MultiLink Trunk Configuration

screen” on page 138 for screen examples and field descriptio ns that will help

you configure your MultiLink Trunks.

212859-A

Spanning tree considerations for MultiLink Trunks

The spanning tree Path Cost parameter is recalculated based on the aggregate bandwidth of the trunk. Fo r exa mple, Figure 39 shows a four-p ort tr unk (T1) wi th two port members operating at an aggregate bandwidth of 2.2 Gb/s, with a comparable Path Cost of 4. When the Path Cost calculations for both trunks are equal, the software chooses the trunk with the larger aggregate bandwidth (T1) to determine the most efficient path.

The switch can also detect trunk member ports that are physically misconfigured. For example, in Figure 40, trunk member ports 2, 4, and 6 of Switch S1 are configured correctly to trunk member ports 7, 9, and 11 of Switch S2.

Additional tips about the MultiLink Trunking feature

When you create a MultiLink Trunk, the individual trunk members (the specific ports that make up the trunk) logically connect and react as a single entity. For example, if you change spanning tree parameters for any trunk member, the spanning tree parameters for all trunk members change.

All configured trunks are indicated in the Spanning Tree Configuration screen. The 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 disable spanning tree participation using the 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 you set the Trunk Status field to Enabled.

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 T1, the management station views trunk T1 as spanning tree port 13.

For more info rmation a bout usi ng the Mul tiLink Trunking feature, see “MultiLink

Trunk Configuration Menu screen” on page 136.

Port mirroring

You can designate one of your switch ports to monitor ingress traffic on a single specified switch port (port-based).

Figure 38 provides a sample Port Mirroring Configuration screen. Note that the displayed screens do not show all of the screen prompts that precede some actions.

For example, when you con figur e a swit ch for port mirror ing or when you mod ify an existing port mirroring configuration, the new configuration does not take effect until you respond [Yes] to the following screen prompt:

Chapter 3 Using the console interface

This chapter describes how to configure and manage the BayStack 380 Switch using the menu-driven console interface (CI).

This chapter covers the following topics:

• “Accessing the CI menus and screens,” next

• “Using the CI menus and screens” on page 94

• “Main menu” on page 96

Accessing the CI menus and screens

You can access the CI menus and screens locally through a console terminal attached to your BayStack 380 Switch, remotely through a dial-up modem connection, or in-band through a Telnet session (see “Console port” on page 26). You can connect your console cable into any BayStack 380 Switch.

Note: If you have a properly configured BootP server in your network, it detects the IP address; you will not need to configure the IP address.

For information about SNMP, see your network management documentation.
