• Layer 3 Enabled ATM Switch Router Hardware (Catalyst 8540 MSR)

• Layer 3 Enabled ATM Switch Router Hardware (Catalyst 8510 MSR and LightStream 1010)

Layer 3 Enabled ATM Switch Router Hardware (Catalyst 8540 MSR)

The Layer 3 enabled ATM switch router uses a 13-slot, modular chassis featuring dual, fault-tolerant, load-sharing AC or DC power supplies. Slots 4 and 8 are occupied by the dual, field-replaceable route processors, which perform central processing functions and provide redundancy. The route processors can also accommodate the network clock module, which features a stratum 3 oscillator and two building integrated timing supply (BITS) ports. Slots 5, 6, and 7 are occupied by either two or three switch processors, for a 20-Gbps non-EHSA or 20-Gbps EHSA switch fabric. The switch processors also accommodate the switch processor feature card.

The remaining slots hold either a full-width module, such as the new four-port OC-12 module, or the carrier module, which in turn accommodates one or two port adapters, such as the four-port OC-3 port adapters. Along with other available interfaces, the ATM switch router provides switched ATM connections to individual workstations, servers, LAN segments, or other ATM switches and routers using fiber-optic, unshielded twisted-pair (UTP), and coaxial cable.

Chapter 1 Product Overview

Layer 3 Enabled ATM Switch Router Hardware Overview

Layer 3 Enabled ATM Switch Router Hardware (Catalyst 8510 MSR and LightStream 1010)

The Catalyst 8510 MSR and LightStream 1010 ATM switch routers both use a five-slot, modular chassis featuring the option of dual, fault-tolerant, load-sharing AC or DC power supplies. A single, field-replaceable ATM switch processor module supports both the 5-Gbps shared memory and the fully nonblocking switch fabric. The processor also supports the feature card and high performance reduced instruction set computing (RISC) processor (CPU) that provides the central intelligence for the device. The remaining slots support up to four hot-swappable carrier modules. Each carrier module can hold up to two hot-swappable port adapters for a maximum of eight port adapters per switch, supporting a wide variety of desktop, backbone, and wide-area interfaces.

The ATM switch provides switched ATM connections to individual workstations, servers, LAN segments, or other ATM switches and routers using fiber-optic, unshielded twisted-pair (UTP), and coaxial cable.

Note The ATM switch processor and port adapters can be installed in the Catalyst 5500 switch chassis. In the

Catalyst 5500 switch chassis the processor must be installed in slot number 13 and the port adapters in slot numbers 9 though 12. The examples in this guide assume that the ATM switch router is in its own chassis, with the processor in slot number 2 and the port adapters in slot numbers 0, 1, 3, and 4.

Processor and Feature Card Models (Catalyst 8510 MSR and LightStream 1010)

The Catalyst 8510 MSR and LightStream 1010 ATM switch routers are equipped with one of the following combinations of processor and feature card:

• ASP-B with feature card per-class queuing (FC-PCQ) or feature card per-flow queuing (FC-PFQ)

• ASP-C with FC-PCQ or FC-PFQ

• Multiservice ATM switch route processor

ASP-B with FC-PCQ and ASP-C with FC-PCQ are functionally equivalent, offering the same features and performance. FC-PFQ, however, provides an enhanced feature set, including advanced traffic management. ASP-B and ASP-C, equipped with FC-PFQ, also provide identical functionality for ATM applications. However, ASP-C with FC-PFQ provides the additional capability for supporting both ATM and Layer 3 switching on the same platform. ASP-C with FC-PFQ and the multiservice ATM switch route processor, used in the Catalyst 8510 MSR, are identical.

FC-PCQ provides a subset of the ATM Forum traffic management features provided by FC-PFQ, as described in Ta ble 1-1.

CHAPTER

Understanding the User Interface

This chapter describes the ATM switch router user interface and provides instructions for using the command-line interface (CLI).

Note This chapter provides advanced configuration instructions for the Catalyst 8540 MSR,

Catalyst 8510 MSR, and LightStream 1010 ATM switch routers. For complete descriptions of the commands mentioned in this chapter, refer to the ATM Switch Router Command Reference publication.

The following sections are included:

• User Interface Overview, page 2-1

• Accessing Each Command Mode, page 2-2

• Additional Cisco IOS CLI Features, page 2-17

• About Embedded CiscoView, page 2-17

• Installing and Configuring Embedded CiscoView, page 2-17

User Interface Overview

The user interface for the ATM switch router provides access to several different command modes, each with related commands. Users familiar with the Cisco IOS user interface will find the interfaces very similar. This chapter describes how to access and list the commands available in each command mode, and explains the primary uses for each command mode.

For security purposes, the user interface provides two levels of command access: user and privileged. The unprivileged user mode is called user EXEC mode; the privileged mode is called privileged EXEC mode, and requires a password.

Note Because all commands available in user EXEC mode are also available in privileged EXEC mode, user

EXEC mode is referred to as EXEC mode in this guide.

From the privileged level, you can access global configuration mode; from global configuration mode you can access numerous submodes that allow you to configure specific, related features. Read-only memory (ROM) monitor mode accesses a basic system kernel to which the ATM switch router may default at startup if it does not find a valid system image, or if its configuration file is corrupted.

OL-7396-01

ATM Switch Router Software Configuration Guide

2-1

Accessing Each Command Mode

You can enter commands in uppercase, lowercase, or a mix of both. Only passwords are case sensitive. You can abbreviate commands and keywords to a minimum unique string of characters. For example, you can abbreviate the show command to sh. After entering the command line at the system prompt, press the Return key to execute the command.

Almost every configuration command has a no form. In general, use the no form to disable a feature or function. Use the command without the no keyword to reenable a disabled feature or enable a feature disabled by default.

Note Refer to the ATM Switch Router Command Reference publication for the complete syntax of commands

specific to the ATM switch router and a description of the function of the no form of a command. Refer to the Configuration Fundamentals Command Reference publication for the complete syntax of other IOS commands.

Accessing Each Command Mode

This section describes how to access the command modes for the ATM switch router. Table 2-1 and

Table 2-2 list the command modes, access to each mode, the prompt you see while in that mode, the main

uses for each configuration mode, and the method to exit that mode. The prompts listed assume the default ATM switch router name “Switch.” Tab l e 2 - 1 and Tab l e 2 -2 might not include all of the possible ways to access or exit each command mode.

EXEC Mode

When you log in to the ATM switch router, you are in user EXEC, or simply EXEC, command mode. The EXEC commands available at the user level are a subset of those available at the privileged level. In general, the user-level EXEC commands allow you to connect to remote devices, change terminal settings on a temporary basis, perform basic tests, and list system information.

The user-level prompt consists of the ATM switch router’s host name followed by the angle bracket (>):

Switch>

OL-7396-01

The default host name is Switch, unless it has been changed during using the hostname global configuration command.

ATM Switch Router Software Configuration Guide

Accessing Each Command Mode

Privileged EXEC Mode

The privileged EXEC command set includes all user-level EXEC mode commands and the configure command, through which you can access global configuration mode and the remaining configuration submodes. Privilege EXEC mode also includes high-level testing commands, such as debug, and commands that display potentially secure information.

To enter privileged EXEC mode from EXEC mode, use the enable command and enter your password; the prompt changes to the ATM switch router’s host name followed by the pound sign (#):

Switch> enable Password: Switch#

To exit from privileged EXEC mode back to EXEC mode, use the disable command.

Switch# disable Switch>

The system administrator uses the enable password global configuration command to set the password, which is case sensitive. If an enable password has not been set, privileged EXEC mode can only be accessed from the console.

Chapter 2 Understanding the User Interface

ROM Monitor Mode

ROM monitor mode provides access to a basic system kernel, from which you can boot the ATM switch router or perform diagnostic tests. If a valid system image is not found, or if the configuration file is corrupted, the system might enter ROM monitor mode. The ROM monitor prompt is the angle bracket:

You can also enter ROM monitor mode by intentionally interrupting the boot sequence with the Break key during loading. For a description of this process, refer to the Configuration Fundamentals Configuration Guide.

To return to EXEC mode from ROM monitor mode, use the continue command:

> continue Switch>

Global Configuration Mode

Global configuration mode provides access to commands that apply to the entire system. From global configuration mode you can also enter the other configuration modes described in the following subsections.

To enter global configuration mode from privileged EXEC mode, enter the configure command and specify the source of the configuration commands at the prompt; the prompt changes to the ATM switch router’s hostname followed by (config)#:

Switch# configure Configuring from terminal, memory, or network [terminal]? <CR> Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#

2-6

ATM Switch Router Software Configuration Guide

OL-7396-01

Chapter 2 Understanding the User Interface

You can specify either the terminal, nonvolatile memory (NVRAM), or a file stored on a network server as the source of configuration commands. For more information, see Chapter 26, “Managing

Configuration Files, System Images, and Functional Images.” The default is to enter commands from the

terminal console.

As a shortcut for accessing the terminal method of configuration, enter the following:

Switch# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#

To exit global configuration command mode and return to privileged EXEC mode, use the exit or end command, or press Ctrl-Z:

Switch(config)# interface atm 3/0/0 Switch(config-if)#

Accessing Each Command Mode

To exit interface configuration mode and return to global configuration mode, use the exit command:

Switch(config-if)# exit Switch(config)#

To exit interface configuration mode and return to privileged EXEC mode, use the end command or press Ctrl-Z:

Switch(config-if)# end Switch#

Interface Addressing Formats (Catalyst 8540)

In the ATM switch router chassis, you specify interfaces in slots 0 through 3 and 9 through 12 using the card/subcard/port format. Slots 4 and 8 each contain a CPU (multiservice route processor). Because the configurations on the primary and secondary route processors are automatically synchronized, they are configured via a single network interface, specified as atm0 or ethernet0. There is no need to configure the secondary separately from the primary, but some show commands allow you to display information about the secondary route processor; in these cases, you specify the interface as atm-sec0 or ethernet-sec0. Slots 5 through 7 contain the switch processors, which have no interfaces. Ta ble 2-3 summarizes this addressing scheme, assuming that slot 4 is the primary route processor and slot 8 is the secondary route processor.

Because the ATM switch router’s operating system is based on Cisco IOS software, its interface provides a number of features that help you use the CLI with greater flexibility, ease, and power. These features includes the following:

• Context-sensitive help—allows you to obtain a list of commands available for each command mode

or a list of available options for a specific command by entering a question mark (?).

• Command history—records a history of commands, allowing you to recall previously entered long

or complex commands.

• Editing—provides the ability to move around the command line, cut and paste entries, control

scrolling, create keyboard macros, and so on.

For information on using these and other features of Cisco IOS software, refer to the Configuration Fundamentals Configuration Guide.

Chapter 3 Initially Configuring the ATM Switch Router

Methods for Configuring the ATM Switch Router

The ATM switch router defaults to a working configuration suitable for most networks. However, you might need to customize the configuration for your network.

Note If your Telnet station or SNMP network management workstation is on a different network from the

switch, you must add a static routing table entry to the routing table. See Chapter 11, “Configuring ATM

Routing and PNNI.”

Terminal Line Configuration (Catalyst 8540 MSR)

The Catalyst 8540 MSR has a console terminal line that might require configuration. For line configuration, you must first set up the line for the terminal or the asynchronous device attached to it. For a complete description of configuration tasks and commands used to set up your terminal line and settings, refer to the Configuration Fundamentals Configuration Guide and Dial Solutions Configuration Guide.

You can connect a modem to the console port. The following settings on the modem are required:

• Enable auto answer mode

• Suppress result codes

You can configure your modem by setting the DIP switches on the modem or by connecting the modem to terminal equipment. Refer to the user manual provided with your modem for the correct configuration information.

Note Because there are no hardware flow control signals available on the console port, the console port

terminal characteristics should match the modem settings.

Terminal Line Configuration (Catalyst 8510 MSR and LightStream 1010)

The ATM switch has two types of terminal lines: a console line and an auxiliary line. For line configuration, you must first set up the lines for the terminals or other asynchronous devices attached to them. For a complete description of configuration tasks and commands used to set up your lines, modems, and terminal settings, refer to the Configuration Fundamentals Configuration Guide and Dial Solutions Configuration Guide.

Configuration Prerequisites

3-2

Consider the following information you might need before you configure your ATM switch router:

• If you want to configure a BOOTP server to inform the switch of its Ethernet IP address and mask,

you need the Media Access Control (MAC) address of the Ethernet port.

• If you want to configure a new ATM address for the switch (an autoconfigured ATM address is

assigned by Cisco), you need an ATM address assigned by your system administrator.

• If you are not using BOOTP, you need an IP address and a netmask address.

Note If an rommon> prompt appears, your switch requires a manual boot to recover. Refer to the

Configuration Fundamentals Configuration Guide for instructions on manually booting from Flash memory.

Chapter 3 Initially Configuring the ATM Switch Router

Configuring the BOOTP Server

The BOOTP protocol automatically assigns an Ethernet IP address by adding the MAC and IP addresses of the Ethernet port to the BOOTP server configuration file. When the switch boots, it automatically retrieves the IP address from the BOOTP server.

The switch performs a BOOTP request only if the current IP address is set to 0.0.0.0. (This is the default for a new switch or a switch that has had its startup-config file cleared using the erase command.)

To allow your ATM switch router to retrieve its IP address from a BOOTP server, you must first determine the MAC address of the switch and add that MAC address to the BOOTP configuration file on the BOOTP server. The following steps provide an example of creating a BOOTP server configuration file:

Command Purpose

Step 1

Step 2

Step 3

Step 4

— Installs the BOOTP server code on the workstation, if it is not

— Determines the MAC address from the label on the chassis.

— Adds an entry in the BOOTP configuration file (usually

Configuring the ATM Address

Configuring the ATM Address

The ATM switch router ships with a preconfigured ATM address. The Integrated Local Management Interface (ILMI) protocol uses the first 13 bytes of this address as the switch prefix that it registers with end systems. Autoconfiguration also allows the ATM switch router to establish itself as a node in a single-level Private Network-Network Interface (PNNI) routing domain.

Note If you chose to manually change any ATM address, it is important to maintain the uniqueness of the

address across large networks. Refer to the Guide to ATM Technology for PNNI address considerations and for information on obtaining registered ATM addresses.

For a description of the autoconfigured ATM address and considerations when assigning a new address, refer to the Guide to ATM Technology.

Modifying the Physical Layer Configuration of an ATM Interface

Manually Setting the ATM Address

To configure a new ATM address that replaces the previous ATM address when running IISP software only, see Chapter 11, “Configuring ATM Routing and PNNI.”.

To configure a new ATM address that replaces the previous ATM address and generates a new PNNI node ID and peer group ID, see Chapter 11, “Configuring ATM Routing and PNNI.”

Modifying the Physical Layer Configuration of an ATM Interface

Each of the ATM switch router’s physical interfaces has a default configuration, listed in Chapter 18,

“Configuring Interfaces.” You can accept the defaults, or you can override them by reconfiguring the

physical interface.

The following example describes modifying an OC-3c interface from the default settings to the following:

• Disable scrambling cell-payload.

• Disable scrambling STS-streaming.

• Change Synchronous Optical Network (SONET) mode of operation from Synchronous Time Stamp

level 3c (STS-3c) mode to Synchronous Transfer Module level 1 (STM-1).

Step 1

Step 2

Step 3

Step 4

To change the configuration of the example interface, perform the following steps, beginning in global configuration mode:

Command Purpose

Switch(config)# interface atm card/subcard/port

Selects the physical interface to be configured.

Switch(config-if)#

Switch(config-if)# no scrambling cell-payload Disables cell-payload scrambling.

Switch(config-if)# no scrambling sts-stream Disables STS-stream scrambling.

Switch(config-if)# sonet stm-1 Configures SONET mode as SDH/STM-1.

Example

The following example shows how to disable cell-payload scrambling and STS-stream scrambling and changes the SONET mode of operation to Synchronous Digital Hierarchy/Synchronous Transfer Module 1 (SDH/STM-1) of OC-3c physical interface ATM 0/0/0:

Switch(config)# interface atm 0/0/0 Switch(config-if)# no scrambling cell-payload Switch(config-if)# no scrambling sts-stream Switch(config-if)# sonet stm-1

To change any of the other physical interface default configurations, refer to the commands in the ATM Switch Router Command Reference publication.

Configuring the IP Interface

Note These IP connections are used only for network management.

To configure the switch to communicate via the Ethernet interface, provide the IP address and subnet mask bits for the interface.

This section includes the following:

• Configuring IP Address and Subnet Mask Bits, page 3-8

• Testing the Ethernet Connection, page 3-9

Configuring IP Address and Subnet Mask Bits

Define subnet mask bits as a decimal number between 0 and 22 for Class A addresses, between 0 and 14 for Class B addresses, or between 0 and 6 for Class C addresses. Do not specify 1 as the number of bits for the subnet field. That specification is reserved by Internet conventions.

To configure the IP address, perform the following steps, beginning in global configuration mode:

Configuring Network Clocking

Configuring Network Clocking with NCDP

The Network Clock Distribution Protocol (NCDP) provides a means by which a network can synchronize automatically to a primary reference source (PRS). To do so, NCDP constructs and maintains a spanning network clock distribution tree. This tree structure is superimposed on the network nodes by the software, resulting in an efficient, synchronized network suitable for transport of traffic with inherent synchronization requirements, such as voice and video.

The following sections provide instructions for configuring NCDP. For a description of how NCDP works, refer to the Guide to ATM Technology.

Note The NCDP is intended for use on ATM switch routers equipped with FC-PFQ or with the network clock

module.

Enabling NCDP

To enable NCDP, use the following global configuration command for each node that you want to configure for NCDP:

Command Purpose

ncdp Enables NCDP.

Configuring Network Clock Sources and Priorities

You must specify the clocking sources, their priorities, and associated stratums used by NCDP in constructing the clock distribution tree. To do so, use the following command in global configuration mode:

Command Purpose

ncdp source priority {{atm | cbr} card/subcard/port stratum | bits stratum | system}

1. Allows you to specify a Building Integrated Timing Supply (BITS) source. This option is available only on the Catalyst 8540 MSR equipped with the network clock module.

{0 | 1}

Configuring Network Clocking

Specifies a priority and source (stratum level or system) for this interface.

If you do not configure a clock source, NCDP advertises its default source of network clock, which is its local oscillator; if no nodes in the network have a clock source configured, the tree is built so that it is rooted at the switch having the highest stratum oscillator (lowest numerical value) and lowest ATM address.

Example

The following example demonstrates configuring the network clock source, priority, and stratum on node A in Figure 3-1.

Switch(config)# ncdp source 1 atm 1/0/0 3 Switch(config)# ncdp source 1 atm 3/0/0 3

Configuring Optional NCDP Global Parameters

Optional NCDP parameters you can configure at the global level include the maximum number of hops between any two nodes, revertive behavior, and the values of the NCDP timers. To change any of these parameters from their defaults, use the following commands in global configuration mode:

Command Purpose

ncdp max-diameter hops Specifies the maximum network diameter for the

ncdp revertive Specifies the NCDP as revertive.

ncdp timers {hello | hold} time-in-msec

jitter-percent

protocol. The default maximum network diameter is 20.

Specifies the values to be used by the NCDP timers.

OL-7396-01

ATM Switch Router Software Configuration Guide

3-15

Configuring Network Clocking

When you specify a maximum diameter, you constrain the diameter of the spanning tree by specifying the maximum number of hops between any two nodes that participate in the protocol. Each node must be configured with the same maximum network diameter value for NCDP to operate correctly.

When you configure the NCDP as revertive, a clock source that is selected and then fails is selected again once it has become operational for a period of time. On the Catalyst 8510 MSR and LightStream 1010 platforms, if NCDP is configured to be revertive, a failed clocking source node after a switchover is restored to use after it has been functioning correctly for at least 1 minute. On the Catalyst 8540 MSR the failed source is restored after about 25 seconds. The network clock is, by default, configured as nonrevertive. Nonrevertive prevents a failed source from being selected again.

Example

The following example shows setting the maximum number of hops to 11 and enabling revertive behavior:

Switch(config)# ncdp max-diameter 11 Switch(config)# ncdp revertive

Configuring Optional NCDP Per-Interface Parameters

Chapter 3 Initially Configuring the ATM Switch Router

On a per-interface basis, you can enable or disable NCDP, specify the cost metric associated with the port, and change the control virtual circuit used to transport protocol messages between adjacent protocol entities. To change any of these parameters from their defaults, use the following commands in interface configuration mode:

Command Purpose

ncdp admin-weight weight Specifies the cost metric associated with the given

port.

ncdp control-vc vpi vci Specifies the VPI/VCI values to use for control VCs on

the physical interface. The default is 0, 34.

Note To change the control VC to a VPI other than

0, the VPI must exist on the physical interface.

no ncdp Disables NCDP on the interface.

Example

The following example demonstrates setting the administrative weight on an interface:

Switch(config)# interface atm 0/0/0 Switch(config-if)# ncdp admin-weight 75

Configuring Network Routing

Network Clock Services for CES Operations and CBR Traffic

Circuit emulation services-interworking functions (CES-IWF) and constant bit rate (CBR) traffic relate to a quality of service (QoS) classification defined by the ATM Forum for Class A (ATM adaptation layer 1 [AAL1]) traffic in ATM networks. In general, Class A traffic pertains to voice and video transmissions, which have particular clocking requirements. For details, refer to Chapter 19, “Configuring Circuit

Emulation Services.”

Configuring Network Routing

The default software image for the ATM switch router contains the Private Network-Network Interface (PNNI) routing protocol. The PNNI protocol provides the route dissemination mechanism for complete plug-and-play capability. The following section, “Configuring ATM Static Routes for IISP or PNNI,” describes modifications that can be made to the default PNNI or Interim-Interswitch Signalling Protocol (IISP) routing configurations.

For routing protocol configuration information, refer to Chapter 10, “Configuring ILMI,”and

Chapter 11, “Configuring ATM Routing and PNNI.”

Configuring ATM Static Routes for IISP or PNNI

Static route configuration allows ATM call setup requests to be forwarded on a specific interface if the addresses match a configured address prefix. To configure a static route, use the following command in global configuration mode:

Command Purpose

atm route addr-prefx atm card/subcard/port Specifies a static route to a reachable address

Note An interface must be User-Network Interface (UNI) or Interim Interswitch Signalling Protocol (IISP) to

be configured with static route. Static routes configured as PNNI interfaces default as down.

The following example shows how to use the atm route command to configure the 13-byte peer group prefix = 47.0091.8100.567.0000.0ca7.ce01 at interface ATM 3/0/0:

Switch(config)# atm route 47.0091.8100.567.0000.0ca7.ce01 atm 3/0/0 Switch(config)#

Configuring Online Diagnostics (Catalyst 8540 MSR)

Online and insertion diagnostics detect and report hardware failures in the Catalyst 8540 MSR during system bootup and operation.

The online diagnostics on the Catalyst 8540 MSR

• Access tests between the route processor and the switch processors, feature cards, port adapters, and

interface modules

• Online insertion and removal (OIR) diagnostic tests

• Snake tests through the switch router to ensure connectivity between the ports

Note Online diagnostics tests only run on the primary route processor.

Access Test (Catalyst 8540 MSR)

The access tests ensure connectivity at a configurable interval between the primary route processor and the following:

• Active switch processors

provide the following types of tests:

OL-7396-01

• Standby switch processor, if it is present

ATM Switch Router Software Configuration Guide

3-19

Configuring Online Diagnostics (Catalyst 8540 MSR)

• Feature cards

• Carrier modules

• ATM port adapters

• ATM and Layer 3 interface modules

• ATM router modules

When the access test detects a hardware failure, the system issues an error message to the console.

If the access test detects a hardware problem with an active switch processor, the standby switch processor, if it is present, automatically takes over and becomes an active switch processor. The system generates an SNMP trap when the switchover occurs.

Note The access test does not support the network clock module.

OIR Test (Catalyst 8540 MSR)

Online insertion and removal (OIR) tests check the functioning of the switch fabric and interfaces on a per-port basis. The switch router performs these tests when the system boots up and when you insert a port adapter or interface module into a slot. The OIR test sends a packet to the interface loopback and expects to receive it back within a certain time period. If the packet does not reach the port within the expected time period, or the route processor receives a corrupted packet, the system issues an error message to the console, generates an SNMP trap, and brings the port to an administrative down state.

Chapter 3 Initially Configuring the ATM Switch Router

Note The size of the packet used in the test is configurable.

The OIR tests support all ATM port adapters, all ATM interface modules, all ATM router modules, and all Layer 3 interface modules except the 8-port Gigabit Ethernet.

Snake Test (Catalyst 8540 MSR)

The snake test detects and reports port-to-port connectivity failures. The snake test establishes a connection across all the active ports in the switch router, originating and terminating at the primary route processor. The route processor establishes a connection by sending a packet to each port in turn, which then terminates at the route processor. If the packet does not reach the route processor within the expected time period, or the received packet is corrupted, further testing is performed to isolate and disable the port causing the problem.The size of the packet and frequency of the test are configurable to minimize the impact on system performance.

The snake test supports Enhanced ATM Router Module (also known as ARMII), all ATM interface modules and enhanced Gigabit Ethernet interface modules. It does not support ATM port adapters, ATM router module (also known as ARMI), 16-port 10/100 Fast Ethernet interface modules, 2-port Gigabit Ethernet interface modules, or 8-port Gigabit Ethernet interface modules.

Note The snake test does not support ATM port adapters because of a hardware limitation in the

carrier module.

Configuring SNMP and RMON

SNMP is an application-layer protocol that allows an SNMP manager, such a network management system (NMS), and an SNMP agent on the managed device to communicate. You can configure SNMPv1, SNMPv2, or both, on the ATM switch router. Remote Monitoring (RMON) allows you to see the activity on network nodes. By using RMON in conjunction with the SNMP agent on the ATM switch router, you can monitor traffic through network devices, segment traffic that is not destined for the ATM switch router, and create alarms and events for proactive traffic management.

For detailed instructions on SNMP and general RMON configuration, refer to the Configuration Fundamentals Configuration Guide. For instructions on configuring ATM RMON, refer to Chapter 15,

“Configuring ATM Accounting, RMON, and SNMP.”
