UPERSTACK

DMINISTRATION

This chapter introduces you to SuperStack™ II Switch 2200 administration

and brieﬂy describes the system parameters that you can conﬁgure.

The Switch 2200 software is installed at the factory in ﬂash memor y on the system processor. Because this software boots from ﬂash memory automatically when you power on your system, the system is immediately ready for use in your network. However, you might need to conﬁgure certain parameters for the system to operate effectively in your networking environment. Additionally, when managing your Switch 2200, you might want to view important MAC, port, bridge, and IP statistics. The Switch 2200 Administration Console allows you to conﬁgure your system and display these important statistics. For more complete network management, you can use an external application, such as 3Com’s Transcend® Enterprise Manager.

Selecting Menu

Options

You select a menu option at the selection prompt by entering its name (or enough of the name to uniquely identify it within the particular menu). For example, to access the system menu from the top-level menu, you enter:

Select a menu option: system

Select a menu option: sy

Menu options are not case sensitive.

When you enter a menu option, you either go to the next menu in the hierarchy or you see information for the option you entered. The information is either a prompt or a screen display. If you enter the menu option incorrectly, you receive a prompt telling you that what you entered was not valid or was ambiguous. You must re-enter the command from the point at which it became incorrect. Expand a truncated command until it becomes unambiguous.

When a new menu appears, the selection prompt (with its choices in parentheses) changes to reﬂect your progression through the menus. For example, if you enter system at the top-level menu and then baseline at the system menu, the prompt changes at the next level:

Entering a

command string

Select a menu option (system/baseline):

Once you are familiar with the menu structure, instead of working your way down the menu hierarchy to a task, you can enter a string of menu options at a selection prompt to go immediately to a task. For example, the command string for setting a baseline from the top-level menu looks like this:

Select a menu option: system baseline set

The most abbreviated version of the same command string is:

Select a menu option: sy b s

When you enter a command string, you move to the last menu level or option you entered in the command string, and information relevant to that command is displayed. I t may be a menu, prompt, or screen display.

Using Menus to Perform Tasks 2-9

If you enter a command incorrectly, you receive a prompt telling you that what you entered was not valid or was ambiguous. You must re-enter the command from the point at which it became incorrect.

Entering Values When you reach the level at which you perform a speciﬁc task, you are

prompted for a value. The prompt usually shows all valid values (if applicable) and sometimes a suggested default value. The default might be the system default or the current user-deﬁned value of that parameter.

The valid values are displayed in parentheses. The default value is in brackets. In this example, ( [

Enabled], shown in brackets, is the default:

Enter a new value (disabled,enabled) [enabled]:

disabled, enabled) are the valid values.

Entering values in

command strings

A command string can also contain the value of a command parameter. If you enter a value at the end of a command string, the task is completed, and you are returned to the previous menu. For example, to disable a baseline from the top-level menu, enter :

Select a menu option: system baseline requestedState

disabled

Getting Out To return to the menu one step higher in the hierarchy or to cancel an

operation that you are currently performing, enter

q, followed by [Return].

To quickly move to the top-level menu without backtracking through menus, press [Esc] (the Escape key). You immediately return to the top-level menu.

To completely leave the Administration Console, see the section “Exiting the Administration Console” on page 2-17.

Administration Console Interface Parameters

Adjusting the

Screen Height

You can change two Administration Console interface parameters: the screen height and the functioning of the reboot and abort control keys.

You can change the Administration Console’s screen height to increase or decrease the space available for displaying information.

The screen height setting does not affect the way the system displays menus. The screen height setting controls the way the system displays information that results from your use of the menus, such as when you request statistical summaries.

You can conﬁgure the screen height to be between 20 to 200 lines or zero (0) for inﬁnite; the default is 24. Most terminal screens have a height of 24 lines.

Each time the screen output reaches the designated screen height, you are prompted to press a key to display more information. To receive no prompts, set the screen height to inﬁnite (0). At this setting, however, the screen output might scroll beyond the screen, depending on your screen size.

As shipped, the Administration Console allows you to use the [Ctrl + X] or [Ctrl + C] key combinations within the Administration Console. These key strokes allow you to reboot the system [Ctrl + X] or restart the Administration Console [Ctrl + C]. You can change this setting to disable both of these features.

CAUTION: If you disable the control keys, only use [Ctrl + C] if instructed to by a Technical Support representative. Using [Ctrl + C] might irregularly terminate an Administration Console session.

To enable or disable the reboot and abort control keys:

1 From the top level of the Administration Console, enter :

system ctlKeys

You are prompted for whether to enable or disable the functionality, as shown here:

Enter new value (disabled,enabled) [enabled]:

2 Enter enabled or disabled at the prompt.

Remote Access Parameters

Preventing

Disconnections

You can reach the Administration Console remotely through a telnet or rlogin session. You can set parameters to prevent disconnections when another user remotely accesses the Administration Console, to enable the Switch 2200 to end remote sessions after a speciﬁed time period, and to specify the time interval before remote sessions are ended.

Because only a single shell is supported by the Administration Console, you might be disconnected from your session if someone else remotely accesses the Administration Console. A terminal connected through the Console serial port can be disconnected by a telnet or rlogin connection.

2-12 CHAPTER 2: HOW TO USE THE ADMINISTRATION CONSOLE

To ensure that your Administration Console session will not be pre-empted by remote access, you can lock the Administration Console. Remote access is prohibited only for that particular session.

The Administration Console is always locked when you are in the middle of a command. For example, the Administration Console is locked during a software update.

CONFIGURING MANAGEMENT A

CCESS TO THE SYSTEM

This chapter describes how to conﬁgure management access to the SuperStack™ II Switch 2200 stackable switch through a serial connection or an IP interface. It also describes how to conﬁgure the Switch 2200 so that you can manage it using the Simple Network Management Protocol (SNMP).

About Management Access

Using a Serial

Connection

Using an IP

Interface

You can access the Administration Console directly through the console serial port. Alternatively, from a PC or workstation, you can access the Administration Console through an Ethernet or FDDI port that has an IP interface conﬁgured for it. Once you establish an IP interface, you can also set up the system to be managed by an SNMP-based network management application, such as 3Com’s Transcend® Enterprise Manager.

Direct access through the console serial port is often preferred because it allows you to stay attached during system reboots.

See the SuperStack™ II Switch 2200 Getting Started Guide for console port pin-outs.

Serial connections are often more readily available at a site than Ethernet connections. A Macintosh or PC attachment can use any terminal emulation program when connecting to the Console serial port. A workstation attachment under UNIX can use an emulator such as tip.

An IP interface allows you to manage the system in-band through any Ethernet or FDDI port. Once an IP interface is conﬁgured, you can rlogin or telnet to the Administration Console using TCP/IP from a host, or you can access the SNMP agent from an external management application. The IP interface has a unique IP address.

By default, the Switch 2200 system provides in-band management through its Ethernet and FDDI ports. In-band management, management using the same network that carries regular data trafﬁc, is often the most convenient and inexpensive way to access your system. If you are using a dedicated network for management data, then you are managing your network out-of-band.

If Spanning Tree is enabled and the port is in the blocking state, in-band management is not functional.

The default baud rate for the Console serial port is 9600. You might need to change the baud rate to match the port speed on your terminal.

Baud rate changes take effect immediately after you conﬁrm the change. Adjust the baud rate of your terminal or terminal emulator appropriately to re-establish communication using the console serial port.

To set the baud rate for the Console serial port:

1 From the top level of the Administration Console, enter :

system consoleSpeed

2 Enter the baud rate for the serial por t.

The system supports the following baud rates: 19200, 9600, 4800, 2400, 1200, and 300.

If you are connected to the Console serial port when you set the baud rate for that serial port, the following message is displayed:

Changing the baud rate may cause a loss of communication since you are currently connected via the serial port. Are you sure you want to change the baud rate? (y/n):

If you respond y (yes), the baud rate is changed immediately. At this time, you lose the ability to communicate on the serial port unless you adjust the baud rate of your terminal or terminal emulator (tip) appropriately. If you respond

n (no), the baud rate does not change, and the previous menu is

displayed.

Setting Up an IP Interface for Management 3-3

Setting Up an IP Interface for Management

General Setup

Process

Administering

Interfaces

IP is a standard networking protocol used for communications among various networking devices. To access the system using TCP/IP or to manage the system using SNMP, you must set up IP for your system as described in this section.

You must ﬁrst deﬁne an interface, which includes assigning an IP address to that interface, and then ping your IP management station to ensure that the connection is alive.

Assign an IP host address to every port for system management.

Then you can ﬁnalize your IP setup by ensuring that the conﬁgurations of the following are correct for your network and changing them as necessary:

■ Routes (See page 3-7)

■ Address Resolution Protocol (ARP) cache (See page 3-11)

■ Routing Information Protocol (RIP) (See page 3-12)

You can monitor IP activity for your system by displaying the IP statistics at any time.

You deﬁne interfaces to establish the relationship between the ports on your system and the subnets in your IP network. You can have up to 32 addresses on a single port and you can assign up to 17 ports per interface.

An IP interface has the following information associated with it:

■ IP Address

This address is speciﬁc to your network. Choose it from the range of addresses assigned to your organization. This address deﬁnes both the number of the network to which the interface is attached and the interface’s host number on that network.

■ Subnet Mask

A subnet mask is a 32-bit number that uses the same format and representation as an IP address. The subnet mask determines which bits in the IP address are interpreted as the network number, which as the subnet number, and which as the host number. Each IP address bit corresponding to a 1 in the subnet mask is in the network/subnet part of the address. Each IP address bit corresponding to a 0 is in the host part of the IP address.

3-4 CHAPTER 3: CONFIGURING MANAGEMENT ACCESS TO THE SYSTEM

■ Broadcast Address

The system uses the IP address when it broadcasts packets to other stations on the same subnet. In particular, the system uses this address for sending RIP updates. By default, the system uses a directed broadcast (all 1s in the host ﬁeld).

■ Cost

The system uses this number, between 1 and 15, when calculating route metrics. Unless your network has special requirements, you should assign a cost of 1 to all interfaces.

■ Por t s

A single interface might contain several bridge ports. All of the ports corresponding to one interface share the same IP address, subnet mask, broadcast address, and cost. The Switch 2200 contains 17 ports: 1 FDDI and 16 Ethernet.

Be sure that the port to which your management station is attached is included in an interface.

Deﬁning an Interface

When you deﬁne an interface, you deﬁne the interface’s IP address, subnet mask, broadcast address, cost, and the collection of system ports associated with the interface.

Table 3-1 shows the recommended settings for the IP interface parameters if you are setting up the system for management.

Deﬁning an interface deﬁnes the IP broadcast domain for frames sourced from the attached segment. To avoid unintentional ﬁltering of IP broadcasts, 3Com recommends that you include all ports. I f you do not assign all ports to this interface, be sure that you include the port to which your network management station is attached.

To deﬁne an IP interface:

1 From the top level of the Administration Console, enter :

ip interface define

You are prompted for the interface’s parameters. To use the value in brackets, press [Return] at the prompt.

2 Enter the IP address of the inter face.

3-6 CHAPTER 3: CONFIGURING MANAGEMENT ACCESS TO THE SYSTEM

3 Enter the subnet mask of the network to which the inter face is to be

connected.

4 Enter the broadcast address to be used on the inter face. 5 Enter the cost value of the interface. 6 Enter the por t(s) that you want to include in the interface. Separate

nonconsecutive ports with commas (,). Enter a consecutive series of ports using a hyphen (-).

Example:

Enter IP address: 158.101.1.1 Enter subnet mask [255.255.0.0]: 255.255.255.0 Enter broadcast address [158.101.1.255]: Enter cost [1]: Ports 1-2=FDDI, 3-18=Ethernet Select port(s) (1-18|all):

If you physically change the conﬁguration of your system after deﬁning IP interfaces, the ports designated for those interfaces might no longer be valid. You should reconﬁgure your interfaces.

Each system maintains a table of routes to other IP networks, subnets, and hosts. You can either make static entries in this table using the Administration Console or conﬁgure the system to use RIP to automatically exchange routing information.

Each routing table entry contains the following information:

■ Destination IP Address and Subnet Mask

These elements deﬁne the address of the destination network, subnet, or host. A route matches a given IP address if the bits in the IP address that corresponds to the bits set in the route subnet mask match the route destination address. When it forwards a packet, if the system ﬁnds more than one routing table entry matching an address (for example, a route to the destination network and a route to the speciﬁc subnet within that network), it will use the most speciﬁc route (that is, the route with the most bits set in its subnet mask).

■ Routing Metric

This metric speciﬁes the number of networks or subnets that a packet must pass through to reach its destination. This metric is included in RIP updates to allow routers to compare routing information received from different sources.

3-8 CHAPTER 3: CONFIGURING MANAGEMENT ACCESS TO THE SYSTEM

■ Gateway IP Address

This address tells the router how to forward packets whose destination address matches the route’s IP address and subnet mask. The system forwards such packets to the indicated gateway.

■ Status

The status of the route provides the information described in Table 3-2.

Table 3-2 Route Status

Status Description

Direct Route to a directly connected network Static Route was statically configured Learned Route was learned using indicated protocol Timing out Route was learned but is partially timed out Timed out Route has timed out and is no longer valid

In addition to the routes to speciﬁc destinations, the routing table can contain an additional entry, called the default route. The system uses the default route to forward packets that do not match any other routing table entry. You might want to use a default route in place of routes to numerous destinations that all have the same gateway IP address.

Defining a Static Route

You might want to deﬁne a static route to transmit system trafﬁc, such as system pings or SNMP response, through a consistent route. Before you deﬁne static routes, you must deﬁne at least one IP interface. (See “Deﬁning an Interface” on page 3-5.) Static routes remain in the table until you remove them, or until you remove the corresponding interface. Static routes take precedence over dynamically learned routes to the same destination.

To deﬁne a static route:

1 From the top level of the Administration Console, enter :

ip route static

You are prompted for the route’s parameters. To use the value in brackets, press [Return] at the prompt.

2 Enter the destination IP address of the route. 3 Enter the subnet mask of the route.

Setting the Default Route

The system uses the default route to forward packets that do not match any other routing table entry. A system can learn a default route using RIP, or you can conﬁgure a default route statically.

If a system’s routing table does not contain a default route, either statically conﬁgured or learned using RIP, then it cannot forward a packet that does not match any other routing table entry. If it cannot for ward a packet for this reason, then it drops the packet and sends an ICMP “destination unreachable” message to the host that sent the packet to notify it of the problem.

Pinging uses the Internet Control Message Protocol (ICMP) echo facility to send an ICMP echo request packet to the IP station you specify. It then waits for an ICMP echo reply packet. Possible responses from pinging are:

■ Alive

■ No answer

■ Network is unreachable. A network is unreachable when there is no route to

that network. To ping an IP station:

1 From the top level of the Administration Console, enter :

ip ping

2 Enter the IP address of the station you want to ping.

IP Address: 192.9.200.40

You could receive one of the following responses:

192.9.200.40 is alive

no answer from 192.9.200.40

For a remote IP address, you can also receive the following response:

Network is unreachable

You should receive a response that the address you pinged is Alive. If you do not receive this response, be sure that you have deﬁned the correct interface values.

community trap

To manage the Switch 2200 from an external management application, you must conﬁgure SNMP community strings and set up trap reporting as described in this section.

You can manage the Switch 2200 using an SNMP-based external management application. This application (an SNMP manager) sends requests to the Switch 2200 system, where they are processed by the Switch SNMP agent.

The SNMP agent provides access to the collection of information about the Switch 2200. In addition, a Switch 2200 SNMP agent sends traps to an SNMP manager to report signiﬁcant events. Access to system information through SNMP is controlled by community strings.

For more information about using SNMP to manage the Switch 2200, see Chapter 3: Management Access: Protocols in the SuperStack™ II Switch 2200

Operation Guide.

You can display the current Switch 2200 SNMP conﬁgurations for the community strings.

To display SNMP settings, enter the following from the top level of the Administration Console:

snmp display

The community string settings are displayed as shown here:

Read-only community is public Read-write community is private

Conﬁguring

Community Strings

A community string is an octet string, included in each SNMP message, that controls access to system information. The Switch 2200 SNMP agents internally maintain two community strings that you can conﬁgure:

■ Read-only community strings with the default “public”

■ Read-write community strings with the default “private”

When an SNMP agent receives an SNMP request, the community string in the request is compared with the community strings conﬁgured for the agent. SNMP get, get-next, and set requests are valid if the community string

3-16 CHAPTER 3: CONFIGURING MANAGEMENT ACCESS TO THE SYSTEM

in the request matches the agent’s read-write community. Only the SNMP get and get-next requests are valid if the community string in the request matches the read-only community.

Setting Up SMT Event Proxying

FDDI SMT events, which occur on the FDDI ring, can be repor ted to stations through the Status Report Protocol. Several SNMP traps, deﬁned in the LANplex Optional FDDI MIB, correspond to some of these events and conditions. If you want your Switch 2200 to report remote SMT events as SNMP traps, you must enable proxying of remote SMT events in that Switch 2200 system.

Local SMT events are automatically reported by the SNMP agent in a Switch 2200 system.

If you have a single Switch 2200 on your network and you have no other way to access FDDI information, then you should enable proxying of SMT events. This conﬁguration provides access to the events occurring locally on the Switch 2200 and to those reported by other stations on the FDDI ring.

If you have multiple Switch 2200s on your FDDI network all reporting to the same SNMP management station, then you can do one of the following:

■ On only one Switch 2200, 1) enable local SNMP traps as described in the

“Conﬁguring Trap Repor ting” on page 3-17 and 2) enable proxying of remote SMT events. On all other Switch 2200s in your network,

1) disable proxying of remote SMT events and 2) enable only SNMP traps that are not SMT-related. SMT-related traps include all of those in the LANplex Optional FDDI MIB. This conﬁguration provides access to the events

3-20 CHAPTER 3: CONFIGURING MANAGEMENT ACCESS TO THE SYSTEM

occurring locally on the one Switch 2200 and to those reported by other stations on the FDDI ring (including other Switch 2200s).

■ Enable local SNMP traps and disable the proxying of remote SMT events on

every Switch 2200 in your network. Local traps will be reported to the management station (which will cover all your Switch 2200s), but SMT events from systems other than Switch 2200s in your network will not be reported.

Normally, statistics for MACs and ports start compiling at system power-up. Baselining allows you to view statistics over the period of time since a baseline was set. By viewing statistics relative to a baseline, you can more easily evaluate recent activity in your system or on your network.

Baselining is maintained across Administration Console sessions. Statistics you view after setting the baseline indicate that they are relative to the baseline. To view statistics as they relate only to the most recent power up, you must disable the baseline.

Baselining affects the statistics displayed for Ethernet ports, FDDI resources, and bridges.

You can display the current baseline to see when the baseline was last set and to determine if you need a newer baseline for viewing statistics.

To display the current baseline, enter the following commands from the top level of the Administration Console:

If you want to transfer NV data from one system to another, save the system’s NV data and restore it as appropriate. You might also want to save a certain conﬁguration of the system for your reference and as a backup. You can also reset system data to its factory-conﬁgured values, if necessary.

During a save, the contents of NV memor y are written out to a disk ﬁle. All conﬁgurable parameters are saved in nonvolatile memory, including:

■ System name

■ System date and time

■ Passwords

■ Packet filters

■ Ethernet port labels

The ﬁle also contains the following information, which is used to resolve any inconsistencies when NV data is restored:

■ Software version number

■ System ID

■ Date and time of creation

■ Data checksums

■ FDDI resources settings

■ Bridge and bridge port settings

■ SNMP community string settings

■ SNMP trap destination configurations

6-2 CHAPTER 6: SAVING, RESTORING, AND RESETTING NONVOLATILE DATA

Saving NV Data When NV data is saved, it is written to a disk ﬁle on a host computer. The

information can then be retrieved from the disk ﬁle when you use the restore command.

To save NV data:

You are prompted for information for saving the data. To use the value in brackets, press [Return] at the prompt. Any entry for IP address, ﬁle name, and user name becomes the new default.

2 Enter the IP address of the station to which you want to save the NV data. 3 Enter the ﬁle path name where you want to save the ﬁle. 4 Enter your user name on the host system. 5 Enter your password on the host system. 6 Enter a name of the ﬁle (optional).

Example:

Host IP Address [158.101.100.1]: 158.101.112.34 NV Data file pathname: usr/jones/systemdata User name: Tom Password: Enter an optional file label:

Labdata

If the information is incorrect or a connection could not be made with the speciﬁed host, a message similar to the following is displayed:

If a session is successfully opened, a system message notiﬁes you of the success or failure of your save as in the following examples:

Success System NV data successfully stored in usr/jones/systemdata

of host 158.101.112.34.

Failure Error - Configuration not stored.

Restoring NV Data 6-3

The failure message varies depending on the problem encountered while saving the NV data.

At the end of the save, you are returned to the previous menu.

Restoring NV Data

When you restore system NV data, the sof tware presents you with a proposal for how to restore the data. This proposal is based on the restoration rules described here:

Rule 1 Exact Match — An exact match is one where the system IDs, module types,

and module revisions (if applicable) all match between the saved conﬁguration and the system on which you are restoring the image.

Rule 2 System ID Mismatch — System IDs do not match between the saved NV ﬁle

and the target system. Mismatches in system IDs are allowed. Before restoring the NV data to a system with a different system ID, you should be aware of the following NV data that might cause problems when restored:

■ Management IP addresses (deﬁned in IP interface conﬁgurations) are saved

as NV data and restored. Before connecting the restored system to the network, you might need to change the IP address of deﬁned interfaces to avoid duplicate IP address problems. Modifying IP inter face deﬁnitions is described on page 3-6.

■ Statically conﬁgured Ethernet addresses are saved as NV data. You must be

sure not to have duplicate addresses when you restore the NV data. Listing statically conﬁgured addresses is described on page 11-11.

If none of these rules succeeds, you cannot apply the saved conﬁguration to the system.

Administering FDDI Stations

An FDDI station is an addressable node on the network that can transmit, repeat, and receive information. A station contains only one Station Management (SMT ) entity and at least one MAC or one port. Stations can be single attachment (one physical connection to the network) or dual attachment (two physical connections to the network).

You can display station information and set the following parameters:

■ Connection policies

■ Neighbor notiﬁcation timer

■ Status reporting

Connection Policies

The connectPolicy attribute is a bit string representing the connection policies in effect on a station. A connection’s type is deﬁned by the types of the two ports involved (A, B, M, or S) in the connection. You can set the corresponding bit for each of the connection types that you want a particular station to reject.

The Switch 2200 FDDI ports can be of type A or B. By default, all connections to the Switch 2200 FDDI ports are valid, except for M-M connections. The possible connections to reject and their corresponding bits are listed in Table 8-2.

FDDI’s dual, counter-rotating ring consists of a primary ring and a secondar y ring. FDDI stations can be connec ted to either ring or to both rings simultaneously. Data ﬂows downstream on the primary ring in one direction from one station to its neighboring station. The secondary ring ser ves as a redundant path and ﬂows in the opposite direction. When a link failure or station failure occurs, the ring “wraps” around the location of the failure, creating a single logical ring.

MAC that is configured in this path. This value can be user-defined.

Setting

tvxLowerBound

The tvxLowerBound attribute speciﬁes the minimum time value of fddiMAC TvxValue that will be used by any MAC that is conﬁgured onto this path. A MAC uses its valid transmission timer (T VX) to detect and recover from certain ring errors. If a valid frame has not passed through a MAC during the time indicated by fddiMACTvxValue, the MAC reinitializes the ring.

By adjusting the tvxLowerBound value, you specify how quickly the ring recovers from an error. The lower you set this value, the faster the net work reacts to problems, but the ring might be reinitialized when there is no problem. The higher you set this value, the less chance of frequent reinitializations, but the network will take longer to recover from errors.

Setting maxT-Req The maxT-Req attribute speciﬁes the maximum time value of fddiMACT-Req

that will be used by any MAC that is conﬁgured onto this path. T-Req is the value that a MAC bids during the claim process to determine a ring’s operational token rotation time, T_Opr. The lowest T-Req bid on the ring becomes T_Opr.

When T_Opr is a low value, the token rotates more quickly, so token latency is reduced. However, more of the ring’s available bandwidth is used to circulate the token. Higher values of T_Opr use less bandwidth to circulate the token, but they increase token latency when the ring is saturated.

An FDDI MAC uses a token-passing protocol to determine which station has control of the physical medium (the ring). The primary purpose of the MAC is to deliver frames (packets) to their destination by scheduling and performing all data transfers. You can display MAC statistics and conﬁgure the following parameters:

■ MAC FrameErrorThreshold

■ NotCopiedThreshold

■ Logical Link Control (LLC) service

All frames on the FDDI network are received promiscuously by an FDDI MAC. However, a frame might be discarded for the following reasons:

■ There is no buffer space available.

■ The frame is in error.

■ LLC service is disabled.

■ This is an NSA Frame and the A-bit is set.

The FrameErrorThreshold attribute determines when a MAC condition report is generated because too many frame errors have occurred. A frame error occurs when a frame becomes corrupted. A high error rate often indicates a faulty station on the FDDI ring or a dirty FDDI connec tor.

Station Management (SMT ) monitors the ratio of frame errors to all frames transmitted within a certain period of time. The FrameErrorThreshold determines at what percentage the frame errors are signiﬁcant enough to report to network management. The threshold value is expressed in a percentage based on 65536 (or 100%). For example, to set the threshold at 1%, the value is 655 (the system default). The lower you set the percentage, the more likely SMT will report a problem.

To set the FrameErrorThreshold:

1 From the top level of the Administration Console, enter :

fddi mac frameErrorThreshold

You are prompted for a MAC number and new value. The Switch 2200 has one MAC, which appears in brackets.

2 Press [Return]. 3 Enter the new threshold value.

The NotCopiedThreshold attribute determines when a MAC condition report is generated because too many frames could not be copied. Not-copied frames occur when there is no buffer space available in the station (which indicates that there is congestion in the station).

SMT monitors the ratio of frames not copied to all frames transmitted within a certain period of time. The NotCopiedThreshold determines at what percentage the frames not copied are signiﬁcant enough to report to network management. The threshold value is expressed in a percentage based on 65536 (or 100%). For example, to set the threshold at 1%, the value is 655 (the system default). The lower you set the percentage, the more likely SMT will report a problem.
