Comm Port

The Comm Port (also referred to as the Console/Comm 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”).

The Console/Comm Port is a DB-9, RS-232- D male serial port connector. Y ou can use this connector to connect a management station or console/terminal to the switch by using a straight-through DB-9 to DB-9 standard serial port cable (see “Connecting the Console/Comm Port” on page 2-10).

The Console/Comm Port is configured as a data communications

Note:

equipment (DCE) connector. Ensure that your RS-232 cable pinouts are configured for DCE connections (see “DB-9 (RS- 232-D) Console/Comm Port Connector” on page D-5).

The console port runs at 9600 baud and uses eight data bits, one stop bit, and no parity as the communications format, with flow control set to disabled.

Uplink/Expansion Slot

304376-B Rev 00

The Uplink/Expansion slot allows you to attach optional media dependent adapters (MDAs) that support a range of media types (see Appendix B, “Media Dependent Adapters” for more information about MDA types available from Bay Networks).

10BASE-T/100BASE-TX Port Connectors

BayStack 350 switch es use 10BASE-T/10 0BASE-TX RJ-45 (8-pin modular) port connectors.

The RJ-45 port connectors on BayStack 450 switches manufactured

Note:

prior to December 1998 are numbered 1 to 12 and 13 to 24, in succe ssion from left to right. Later uni ts use por t conn ectors t hat are c onf igure d with one o r tw o dual, six-port groups, numbered 1 to 12 and 13 to 24. The top rows are odd numbered and the bottom rows are even numbered (see Figure 1-2

page 1-2

). Port-specific examples in this guide show the appropriate port

connections when required; other examples apply to both versions.

1-3

Using the BayStack 350 10/100/1000 Series Switch

All BayStack 350 switche s are shipped with por t connectors c onfigur ed as MDI-X (media-dependent int erface-cr ossov er). These ports conne ct over st raight cables to the network in terface contro ller (NIC) card in a node or server, similar to a conventional Ethernet repe at er hub. If you a re c onne cti ng to another Ethernet hub or Ethernet switch, you need a crossover cable unless an MDI connection exists on the associated port of the attached device (see “MDI and MDI-X Devices” on page D-2).

The switches use autosensing port s that are de signed to operate at 10 Mb/s or at 100 Mb/s, depending on the connecting device. These ports support the IEEE

802.3u autonegotiation standard, which means that when a port is connected to

another device that also supports the IEEE 802.3u standard, the two devices negotiate the best speed and duplex mode of operation.

The switch ports also support half- and full-duplex mode operation (see “Connecting the 10BASE-T/100BASE-TX Ports” on page 2-9).

The switch uses 10BASE-T/100BASE-TX RJ-45 port connectors to connect to 10 Mb/s or 100 Mb/s Ethernet segments or nodes.

Use only Category 5 copper unshielded twisted pair (UTP) cable

Note:

IEEE 802.1Q VLANs

BayStack 350 switches support up to 64 port-based VLANs with IEEE 802.1Q tagging available per port. When a switch port is configured to be a member of a VLAN, it is added to a group of ports (workgroup) that belong to one broadcast domain. You can assign d if f erent port s (and ther efore the d e vic es att ached to t he se ports) to different broadcast domains. This feature allows network flexibility because you can reassign VLANs to accommodate net work move s, additions , and changes, eliminating the need to change physical cabling.

For more information about 802.1Q VLANs, see “

Workgroups” on page 1-18.

Using the BayStack 350 10/100/1000 Series Switch

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 version 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 3-70).

For information about connecting a console terminal for this procedure, see “Connecting the Console/Comm Port” on page 2-10.

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.

Certain configuration parameters, including the system characteristics strings, some VLAN para meters, the IGMP configuration para meters, and the MultiLink trunk names are stored in flash memory. These parameters are updated every 10 minutes or whenever a Reset command is executed. Powering off the switch within 10 minutes of changing these configuration parameters can cause the configuration parameters to be lost.

BootP Automatic IP Configuration

The BayStack 350 switch has a unique 48-bit har dware address, 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 F, “Sample BootP Configuration Fil e.”

SNMP MIB Support

The BayStack 350 switch supports an SNMP agent with industry standard MIBs, as well as private MIB extensions, which ensures compatibility with existing network management tools. The BayStack 350 switch supports MIB-II (RFC 1213) and the RMON MIB (RFC 1757), which provide access to detailed management statistics. With SNMP management, you can configure SNMP traps (on individual ports) to be generated automatically for conditions such as an unauthorized access attempt or changes in a port’s operating status.

Autosensing and Autonegotiation

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 autonegoti at ion refers t o a st andard ized p rotoco l (I EEE 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.

BayStack 350 10/100/1000 Series Switches

304376-B Rev 00

Autosensing is use d whe n t he a tt ached devic e i s not capable of au ton egotiation 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 4-6.

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 any 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/Comm Port or BootP, which resides on the switch.

For more information about using the Console/Comm Port to configure the switch, 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 other b y c onnecting these devices directly to the switch, through a shared medi a hub that is conn ected to t he switch , or by creat ing a virt ual LAN (VLAN) through the switch.

This section provides three network configuration examples using BayStack 350 10/100/1000 Series Switches:

IEEE 802.1Q VLAN Workgroups

BayStack 350 switches support up to 64 port-based VLANs with 802.1Q tagging ava il abl e per port . Port s are group ed into broadcast domains by as si gni ng them to the same VLAN. Frames received in one VLAN can only be forwarded within that VLAN, and IP Multicast frames and unknown unicast frames 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 1-8 segment that i s a single broadcast domai n. Wh en a sw it ch p ort is config ure d to be a member of a VLAN, it is added to a group of ports (workgroup) that belong to one broadcast domain.

BayStack 350 switches allow you to assign ports to VLANs using the console or TELNET; VLAN assignment is not currently available through SNMP. 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 350 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 the frame

header that identifies an explicit VLAN.

• Port VLAN Identifier (PVID) --- a cl assification mechanis m that ass ociat es 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) wi th this class ific ation as the y lea ve th e switch throug h a port that is configured as a tagged port.

• Untagged frame --- a frame that does not carry any VLAN tagging

information 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.

BayStack 350 10/100/1000 Series Switches

304376-B Rev 00

• 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 he ader is modi f ied to i nclude the 32-bi t ta g ass ociat ed wit h the PVID. When a tagged frame exits the switch through a tagged member port, the frame header remains unchanged (original VID remains).

• User_priority --- a three-bit field in the header of a tagged frame. The field is

interpreted as a binary number, therefore has a value of 0 to 7. This field allows th e t agged frame to carr y t he user-priority across bridged LANs where the individual LAN segments may be unable to signal priority information.

• Port p riority --- the priority level assigned to untagged frames received on a

port. This value be comes the user _priority fo r the frame. Tagged packets get their user_priority from the value contained in the 802.1Q frame header.

• Unregistered packet --- a tagged frame that contains a VID where the

receiving port is not a member of that VLAN.

1-19

Using the BayStack 350 10/100/1000 Series Switch

• Filtering Database Identifier (FID) --- the specific filtering/forwarding

database within the BaySta ck 35 0 sw it ch t hat is a ssi gned to each VLAN. The current version of software assigns all VLANs to the same FID. This is referred to as Shared VLAN Learning in the IEEE 802.1Q specification.

The default configuration settings for BayStack 350 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) which distinguishes it from all other VLANs. In the default configuration example shown in Figure 1-9 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 connecting 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 por t for a VLAN, all frames lea ving the port for that VLAN are marked as belonging to that specific VLAN. Users can assign specific switch ports as members of one or more VLANs that span multiple switches, without interfering with the spanning tree protocol.

Because there is only one link between the two switches, the Spanning Tree Protocol (STP) treats t his configurat ion as any other switc h-t o- swit ch connection. For this configuration to work properly, both switches must support the 802.1Q tagging protocol.

As shown in Figure 1-16, with STP enabled, only one connection between switch S1 and S2 is forwarding at any time. Communications failure occurs between VLAN 2 of S1 and VLAN 2 of S2, blocking communic at ions between Stations A and B.

The link connecting VLAN 1 on swit ches S1 and S2 is selected a s th e fo rwarding link based on port speed, duplex-mode, and port priority. Because the other link connecting VLAN 2 is placed into Bl ocki ng mode, stations on VLAN 2 in switch S1 cannot communicate with stations in VLAN 2 on switch S2. With multiple links only one link will be forwarding.

VLAN Configuration Rules

VLANs operate according to specif ic conf igu ration rules. When crea ting VLANs, consider the following rules that determine h ow the configured VLAN reacts 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

• 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.

• VLANs are not dependent on Rate Limiting settings.

• If a port is an IGMP member on any VLAN, and is removed from a VLAN,

the port’s IGMP membership is also removed.

• If a port is added to a different VLAN, and it is already configured as a Static

Router port, the port is configured as an IGMP member on that specific VLAN.

IGMP Snooping

BayStack 350 switches can sense IGMP Host Members hip Report s from atta ched stations and can use this information to set up a dedicated path between the requesting stati on and a l ocal IP Multicast router. Once the pathway is establ ished, the BayStack 350 switch blocks the IP Multicast stream from exiting any other port that does not connect to another Host Member, thus conserving bandwidth. The following describes how BayStack 350 switches provide the same benefit as IP Multicast routers, but in the local area:

IGMP (internet group management protocol) is a protocol (see RFC 2236) that is used by IP Multica st rout ers to lea rn the e xi stenc e of h ost grou p member s on thei r directly attached subnets. The IP Multicast routers learn about the existence of host groups by broadcasting IGMP queries and listening for IP hosts reporting their host group memberships. This process is useful for the client/server relationship that exists betw een an IP Multicast source that provides data streams to clients wanting to rec eive the data.

Figure 1-24

shows how IGMP is used to set up the path between the client and server. As shown in this example, the IGMP host provides an IP Multicast stream to designated routers which only forwar d the IP Multicast stream on th eir local network if there is a recipient.

The client/server path is set up as follows:

The designated router sends out a Host Membership Query to the subnet and receives Host Membership Reports from end stations on the subnet.

The designated routers then set up a path between the IP Multicast stream source and the end stations.

Periodically, the router continues to query end stat ions on whether to continue participation.

As long as any client continues to participate, all clients, including non-participating endstations on that subnet, receive the IP Multicast stream.

Note:

Although the non-participating endstations can filter the IP Multicast

traffic, the IP Multicast still exists on t he subnet and c onsumes band width.

IP Multicast can be optimized in a LAN by using IP Multicast filtering switches, such as the BayStack 350 10/100/1000 Series Switches.

One client, connected to S2, responds with a host membership report. Switch S2 intercepts the report fro m that port, and generates a proxy report to its upstream neighbor, S1. Also, two clients connected to S4 respond with host membership reports, causing S4 to intercept the reports and to generate a consolidated proxy report to its upstream neighbor, S1.

IGMP Snooping Configuration Rules

The IGMP Snooping feature operates according to specific configuration rules. When configuring your switch for IGMP Snooping, consider the following rules that determine how the configuration reacts in any network topology:

• A port that is configured for port mirroring cannot be configured as a Static

Router port.

• If a MultiLink trunk member is configured as a Static Router port, all of the

MultiLink trunk members are configured as Static Router ports. Also, if a Static Router port is removed, and it is a MultiLink trunk member, all MultiLink trunk members are removed as Static Router port members, automatically.

• Static Router ports must be port members of at least one VLAN.

• If a port is configured as a Static Router port, it is configured as a Static

Router port for all VLANs on that port. The IGMP configuration is propagated through all VLANs of that port.

• If a Static Router port is removed, the membership for that port is removed

from all VLANs of that port.

1-38

• The IGMP Snooping feature is not STP dependent.

• The IGMP Snooping feature is not Rate Limiting dependent.

• The Snooping field must be enabled for the Proxy field to have any va lid

meaning.

• Static Router ports are configured per VLAN and per IGMP Version.

Note:

Because IGMP Snooping is set up per VLAN, all IGMP changes are

implemented according to the VLAN configuration for the specified ports.

For more information about using the IGMP Snooping feature, see “IGMP Configuration” on page 3-48.

See also Appendix C, “Quick Steps to Features” for configuration flowcharts that can help you use this feature.

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 s egment to a hi gher prior ity le v el (b y def ault , all switc h ports ar e set to Low priority). Untagged packets received by the switch on that port are tagged according to the priority level you assign to the port (see Figure 1-27

Figure 1-28. Port Transmit Queue

As shown in Figure 1-28, the switch provides two transmission queues, a High transmission queue and a Low transmissi on que ue, f or any giv en port. Frames are assigned to one of these queues on the basis of user_priority using a traffic class table. This table is managed by using the Traffic Class Configuration screen (Figure 1-29

). The table indicates the corresponding traffic class that is assigned to the frame, for each possible user_pr iority value. If the frame leaves the switch formatted as a tagged packet, the traffic cla ss assigned to the frame i s carried forward to the next 802.1p capable switch. This allows the packet to carry the assigned 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 shown in the example Figure 1-27

For more information about using the Traffic Class Configuration screen, see “VLAN Configuration” on page 3-22.

To configure the port p riority level, follow these steps:

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

User priority le v els are a ssigned def ault se ttin gs in all BaySt ack 350 switch es. The range is from 0 to 7. The traffic class table can be modified. Therefore, view the settings shown in the Traffic Class Configuration screen before setting the port priority in the VLAN Port Configuration screen.

MultiLink Trunks

MultiLink trunks allow you to group up 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 800 Mb/s in full-duplex mode). BayStack 350 switches can be configured with up to six MultiLink trunks. MultiLink Trunking software detects misconfigured (or broken) trunk links and redirects traffic on t he misconfigu re d or br ok e n trunk link to other trunk members within that trunk.

You can use the Trunk Configuration screen to create switch-to-switch and switch-to-server MultiLink trunk links (see Figure 1-31

BayStack 350 10/100/1000 Series Switches

and Figure 1-32).

304376-B Rev 00

Figure 1-31. Switch-to-Switch Trunk Configuration Example

1-43

Using the BayStack 350 10/100/1000 Series Switch

Each of the trunks shown in Figure 1-31 can be con figured 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 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 1-32

shows a typical swi tch-t o-ser v er tru nk conf i gurati on. In thi s e xample, file server FS1 utilizes dual MAC addresses, using one MAC address for each Network interface controller (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 Utilizing MultiLink Trunks

Figure 1-33 shows an example of how MultiLink trunking can be used in a

client/serv e r c onfiguration. In this example, bot h servers are connected directly t o switch S1. FS2 is connected through a trunk configuration (T1). The switch-to-switch connections are through trunks (T2, T3, T4, and T5).

1-44

304376-B Rev 00

BayStack 350 10/100/1000 Series Switches

Clients accessing data from the servers (FS1 and FS2) are provided with maximized bandwidth through trunks T1, T2, T3, T4, and T5. Tr unk members (the ports making up each trunk) do not have to be consecutive switch ports; they can be selected 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, trunks T2 and T3 must be configured into separate VLANs for this configuration to function properly (see “IEEE 802.1Q VLAN Workgroups

” on page 1-18).

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 configuration rules, must be consid ere d 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.”

BayStack 350 10/100/1000 Series Switches

Determine which switch ports (up to four) are to become (the specific ports making up the trunk):

A minimum of two ports are required for each trunk.

Ensure that the cho sen swi tch por ts are set to Ena bled, us ing t he Port Configuration screen (see “Port Configuration” on page 3-30) or through network management.

Trunk member ports must be in the same VLAN.

All network cabli ng should be comp lete and stabl e bef ore conf igur ing any trunks, to avoid configuration errors.

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

Consider how existing VLANs will be affected by the addition of a trunk.

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:

trunk members

” on page 1-57).

304376-B Rev 00

• Any port that participa tes in Mult iLink Trunking must be an active port (se t to

Enabled via the Port Configuration screen or through network management).

1-55

Using the BayStack 350 10/100/1000 Series Switch

• All trunk members must be configured into the same VLAN before the Trunk

Configuration screen’s Trunk Status field can be set to Enabled (See “VLAN Configuration” on page 3-22).

• When an activ e p ort is conf igured in a trunk, the por t becomes a t runk member

as soon as the Trunk Status field is set to Ena bled. Af ter the Trunk Status field is set to Enab led, the spanning tree parameters 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

precedence over that of any trunk member. W hen a trunk is active, the trunk STP setting can be changed from ei ther th e Trunk Confi gurati on scre en or the Spanning Tree Configuration screen.

• If the VLAN settings of any trunk member are changed, 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. The removed trunk member has to be reconfigured through the Trunk Configuration screen to rejoin the trunk. A screen prompt precedes this acti on. A t r unk member cannot be disabl ed i f t he re are onl y two trunk members on the trunk.

” on page 1-57.

1-56

• A trunk member cannot be configured as a monitor port (see “Port Mirroring

Configuration” on page 3-41).

• Trunks cannot be monitored by a monitor port; however, trunk members can

be monitored (see “Port-Based Mirroring Configuration

” on page 1-62).

• All trunk members must have identical IGMP Snooping configurations.

• If the IGMP Snooping configuration for any trunk member is changed, the

IGMP Snooping settings for all trunk members are changed.

304376-B Rev 00

Spanning Tree Considerations

The spanning tree Path Cost parameter is recalculated based on the aggregate bandwidth of the trunk. For example, Figure 1-39 with two port members operating at 100 Mb/s and the other two port members operating at 10 Mb/s. Trunk T1 provides an aggregate bandwidth of 220 Mb/s. The Path Cost for T1 is 4 (Path Cost = 1000/LAN speed, in Mb/s). If a second three port trunk (T2) is conf igure d with an aggr ega te bandwidth of 210 Mb/s, with a comparable P ath Cost of 4, the swi tch s oftw are c hooses the tr unk wit h the lar ger bandwidth (T1) to determine the most efficient path.

The switch can also detect trunk member ports that are physically misconfigured. For example, in Figure 1-40

, trunk member ports 2, 4, and 6 of switch S1 are configured correctly to trunk member ports 7, 9, and 11 of switch S2. The Spanning Tree Port Configuration screen for each switch shows the port State field for each port in the Forwarding state.

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) are logically connected 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 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 disa ble s pann ing t ree p arti cipat ion 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 the Trunk Status field is set 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.

Port Mirroring (Conversation Steering)

You can designate one of your swit ch ports t o monit or tra ffic on any two specified switch ports (port-based) or to monitor traffic to or from any two specified addresses that the switch has learned (address-based).

Note:

A probe device, such as the Bay Networks StackProbe™ or equivalent, must be connected to the designated monitor port to use this feature (contact your Bay Networks sales agent for details about the StackProbe).

The following sections provide example configurations for both monitoring modes available with the Port Mirroring feature:

• Port-based Mirroring

• Address-based Mi rroring 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 configuration complete? [ Yes ]

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 or IGMP member, and cannot be used for normal switch functions.

• 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 of the mirrored ports, port X and port Y, have the same configuration. Use the VLAN Configuration screen to configure the VLAN (see “VLAN Configuration” on page 3-22).

• 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.

BayStack 350 10/100/1000 Series Switches

304376-B Rev 00

• For port-based monitoring of traffic, use one of the following modes for monitoring broadcast, IP Multicast, or unknown DA frames:

Monitor all traffic received by port X. Monitor all traffic transmitted by port X. Monitor all traffic received and transmitted by port X. Monitor all traffic received by port X or transmitted by port Y.
