ASX-200BX ATM switch and the

and LAN/WAN internetworking applications. Together with the ForeRunner series of ATM LAN and WAN Network Modules, these switches meet the networking demands of today’s distributed, time-critical applications.

All of the F oreRunner ATM switches deliver high-performance switching capacity and speed for ATM applications. A non-blocking s witching capacity of 2.5 Gbps is con tinually avai lable on the ASX-200, the ASX-200WG, and the ASX-200BX. Each switch provides up to 4 ports of connectivity, each running at speeds up to 622 Mbps; or up to 16 ports, each running at speeds up to 155 Mbps; or up to 24 ports, each running at speeds up to 100 Mbps. The

ASX-1000 provides 10 Gbps of switching capacity for up to 16 ports of connectivity, each running at speeds up to 622 Mbps; or up to 64 ports, each running at speeds up to 155 Mbps; or up to 96 ports, each running at speeds up to 100 Mbps.

Wide-area network (WAN) connectivity is seamlessly integrated into the AS X-200BX and the ASX-1000 for connection to private networks or ATM SONET, DS3, DS1, E3, E1, or J2 services.

Interconnecting multiple ForeRunner sw itches at various speeds i s simple. Once a new sw itch is added to the network, all other switches recognize it s presence and dynamically establish connections to ports on the new switch. Furthermore, scaling th e network is accomplished without costly and time consuming address reconfiguration and LAN segmentation.

1.2 Switch Hardware Components

1.2.1 Switch Board

The switch board (also referred to as the “switch fabric”) contains the VPI/VCI lookup tables and routing circuitry to ensure that a cell received from an input port is correctly switched to one or more output ports. The ASX-200, the ASX-200WG, and the ASX-200BX each come with one switch board. The ASX-1000 can be populated with as many as four switch boards. Each switch board can accept up to four network modules, which themselves ca n contain up to six ports each. The switch board also has an interface, controlled by the SCP, that is functionally equivalent to an ATM host interface.

1.2.2 Switch Control Processor

The SPARC RISC SCP in the ASX-200 and the i960 SCP in the ASX-200WG, ASX-200BX, and the ASX-1000 provide the distributed connection setup for a network of ATM switches. The SCP primarily provides management access through SNMP and is responsibl e for storing and updating all SNMP managemen t information. Additionally, the SCP has direct access to the switch board. The SCP, and associated software, manages the behavior of the switch board (i.e., connection setup), but is not involved in the actual cell switching.

1.2.2.1 SPARC RISC Switch Control Processor

The front panel of the ASX-200’s SPARC RISC SCP includes a RESET switch; an ABORT switch; three single LEDs: the RUN/RESET LED, the VME BM (Bus Master) LED, and the STATUS LED; a diagnostics display; two serial ports (labeled A and B); and an Ethernet port. All of the features are illustrated in Figure 1.5 and are described in the subsections that follow.

Switch Hardware

1.2.2.1.1 RESET Switch

The RESET switch on the SPARC RISC SCP allows the user to reset the SCP. After a reset, all open ATM Management Interface (AMI) sessions are ended on the SCP, and all ports on the switch board lose any active sessions and initially go off-line. The ports then return to the configuration stored in the configuration database (CDB).

1.2.2.1.2 ABORT Switch

When activated, the ABORT switch on the ASX-200 causes the SCP to go into Open Boot PROM mode. This mode allows the user to run diagnostics on the controller hardware from a terminal connected to Serial Port A. The SCP halts normal switch operations when in the Open Boot PROM mode.

1.2.2.1.3 RUN/RESET LED

The RUN/RESET LED is red when any reset signal on the sw itch is active. It is off when the switch itself is not active. In all other cases, it is green.

1.2.2.1.4 VME BM LED

The VME BM LED on the ASX-200 reflects all accesses from the SCP to the ASX-200 switch board. When the SCP accesses the switch , this LED illuminates green. In all oth er cases, it is off.

Switch Hardware

1.2.2.1.5 STATUS LED

The STATUS LED on the ASX-200 indicates that the SCP is functional by illuminating green. In all other cases, it is off.

1.2.2.1.6 Diagnostics Display

The diagnostics display on the ASX-200 performs a count during a boot as part of normal power-up diagnostics. A short LED test causes the display to flash a series of numbers indicating that the switch is booting properly. This display is only functional during the boot-u p p rocess.

1.2.2.1.7 RS-232 Serial Ports

The RS-232 serial ports (A and B) on the ASX-200 provide terminal access for any VT100 (or similar) terminal or terminal emulation package to the SCP.

Hardware/software flow control is not

The Ethernet AUI port on the front panel of the ASX-200’s SCP has a standard DB-15 female connector to provide Ethernet access to the switch.

1.2.2.2 i960 Switch Control Processor

The front panel of an i960 SCP for the ASX-200WG, ASX-200BX, and the ASX-1000 includes the following features: a RESET button, an RS-232 serial port, an Ethernet 10BaseT port, a NEXT pushbutton, a SELECT pushbutton, a display LED, and a power LED. All of the features are illustrated in Figure 1.6 and are described in detail in the subsections that follow.

Figure 1.6 - i960 Switch Control Processor Front Panel

1.2.2.2.1 RESET Button

The RESET button allows the user to reset the switch control software on the SCP. Using RESET “soft boots” the SCP a nd runs the init ial powe r-on diagnosti cs. A ll open AM I se ssion s are ended by the SCP, and all ports lose any active sessions and initially go off-line after a reset. The ports then return to the configuration stored in the CDB. Because the RESET button is small (to avoid accidental resets), it is recommended that you use a straightened paper clip to push the RESET button.

1.2.2.2.2 RS-232 Serial Port

The RS-232 serial port provides terminal access for any VT100 (or similar) terminal or terminal emulation package to the SCP. The serial port has a standard DB-9 female connector as shown in Figure 1.7.

1.2.2.2.4 CTL Port

A control port inside the SCP, referred to in the switch software as the CTL port, is a logical (not physical) location where cells that are d irected to the SCP itself are sent. The CTL port has two roles, serving as both a host and a s witch board controller. All signalling from the switch host and every attached host must interact with the switch board controller.

1.2.2.2.5 NEXT Pushbutton

The NEXT pushbutton lets you scroll through the menu th at is shown on the display LED after the power is turned on or after the SCP is reset/rebooted.

The SELECT pushbutton lets you choose an option from the menu that is shown on the display LED after the power is turned on or after the SCP is reset/rebooted.

1.2.2.2.7 Display LED

During the boot process and the initial power-on diagnostics, the displa y LED shows messages about what is happening to the SCP. It is also used to show the men u choices for the NEXT and SELECT pushbuttons after the power is turned on or after the SCP is reset/rebooted. The choices shown on the display LED are as follows:

Flash ?

When chosen, the SCP will attempt to boot from the FLASH file.

Ethernet ?

Monitor ?

When chosen, the SCP boots from the network. When chosen, the user can connect a terminal to the

serial port and run hardware self-diagnostics.

Auto ?

When chosen, the SCP will attempt to boot from the FLASH. If this is unsuccessful, then the SCP will perform an Ethernet boot.

To access the modes listed above, press the NEXT pushbutton while the switch is booting until the mode you want to access is displayed LED. Then, press the SELECT pushbutton.

After the boot process and self-diagnostics are complete, the name of the SCP is shown in the display LED during normal operations, if an SCP name has been assigned. If an SCP name has not been assigned, it will display ATM SWITCH. For information on creating or modifying the SCP name, please refer to the section on configuring the SCP name in the ATM Management Interface Manual.

1.2.3 Dual SCP Setup

This section explains SCP failover support, a vailable when two SCPs a re installed in a single ASX-200BX or ASX-1000 switch fabric. For more information about configuring dual SCP’s via AMI, see the ATM Management Interface Manual.

Only SCP-ASXHAs, or later, support the dual

NOTE

SCP configuration. Using an earlier version SCP in a redundant configuration can cause irreparable damage to your switch fabric.

Switch Hardware

When two SCPs are installed in a switch fabric, the switch recognizes their presence and automatically runs in dual SCP mode. When the switch boots, the SCP which resides in slot X is designated as the primary SCP by default. However, this designation can be altered via AMI. The SCP which resides in slot Y is designated as the standby SCP by default.

While in dual SCP mode, the controlling SCP emits a “heartbeat” at regular intervals. This heartbeat is monitored by the standby SCP. In the event of a hardware failure on the controlling SCP, the heartbeat disappears and the standby SC P takes over.

ForeRunner

ATM Switch User’s Manual

1 - 9

Switch Hardware

Switch configuration information (i.e., CDB configuration, FLASH configuration, etc.) can be synchronized between the controlling and standby SCP so that this inform ation is maintained if SCP failover occurs.

If a failure is detected on the controlling SCP, th e standby SCP takes control of the fabric. At this point, PVC connections are dropped, and any SVCs that had been established are torn down at the switch. Once the standby SCP takes contro l of the switch fabric, PVCs will be reestablished (according to the “last-synchronized” CDB), and end-stations will signal the switch to create new SVCs. The larger the CDB (e.g., number of PVCs), the longer the standby SCP w ill take to fully restore the switch.

The failed SCP can then be removed and replaced with another HA-based SCP.

A standby SCP (SCP-ASXHA or later) can be

NOTE

hot-inserted into the slot from which a failed SCP has been removed.

Repeated and successive hot-insertion or removal of a standby SCP can potentially cause a reset on the primary SCP. This occurrence is intermittent, but will result in cell loss if it does occur.

For proper synchronization of information

NOTE

between SCPs, ensure that the amount of free space on both SCPs is roughly equal before performing these commands.

1.2.3.1 Adding a Standby SCP

If only one SCP is instal led in the switch fabric, it a utomatically assu mes itself to be the co ntrolling SCP. In this case, the S CP periodically checks the fabric for the presence of a second SCP. If a second SCP is detected, the switch will begin to run in dual SCP mode.

While in dual mode, the controlling SCP continually monitors the presence of the standby SCP. If the controlling S CP fails to detect a second S CP, the controlling SCP disab les all synchronization and runs in standalone mode (not dual).

ForeRunner

ATM Switch User’s Manual

Switch Hardware

1.2.3.2 Rebooting the Controlling SCP

When the switch is running in dual mode, a reboot request on the controlling SCP (i.e., after a software upgrade) will not cause the standby SCP to take control of the switch. Instead, the controlling SCP will send a pause signal to the s tandby SCP.

This pause request will force the standby SCP to disregard the absence of the controlling SCP for two minutes. Once the controlling SCP co mes back up, both SCPs will assume normal, dual mode operation.

1.2.3.3 Ethernet Connection

When two SCPs are installed in an ASX-200BX, Ethernet connectivity is only available if the Ethernet port on each SCP is physically connected to the network. If dual SCP mode is utilized on an ASX-1000, the Ethernet connection can be made using the individual SCPs or the Ethernet port on the ASX-1000’s Common Equipment Card (CEC).

If the SCP is accessed via ATM, the Ethernet connection is not necessary.

If two SCPs are installed in a switch fabric, each

NOTE

SCP must have its own entry in the bootpta b file (used for network booting) to a ssign each SCP a unique IP address. Using only one entry (i.e., the same IP address) causes unpredictable Ethernet ARP behavior (see Chapter 4 for more information).

1.2.4.1 Port Numbering

The individual ports on a network module are numbered according to the Board-Network Module-Port (BNP) notation.

Board Refers to the number of the switch board that

contains the port being numbered. “Board” is always 1 in an ASX-200, ASX-200BX, or an ASX-200WG, since these switches each contain only one switch board. “Board” can be 1, 2, 3, or 4 in an ASX-1000, depending on the number of the physical switch board that contains the port being numbered.

Network Module Refers to the slot (A, B, C, or D) in the switch board

that contains the port being numbered.

Port Refers to the physical port (1 - 6) being numbered on

the individual network module.

For example, according to this notation, the fourth port on a network module in slot B of switch board #2 is port 2B4.

1.2.5 Power Supply Modules

The ASX-200BX and the ASX-1000 each come with two removable power supply modules, either AC or DC. In the event of a single power supply failure, the power supply indicator LED(s) on the front panel of the supplies will indicate the failed supply. The failed power supply can be removed and replaced while the other supply continues to provide power to the enclosure. In this manner, a single power supply failure will not cause the switch to stop functioning.

WARNING!

The ASX-200 and the ASX-200WG come with internal, non-removable power supplies. Attempting to remove these power supplies could result in serious injury or may cause permanent damage to the unit.

1.2.5.1 ASX-200BX AC Power Supply

The ASX-200BX has two power supply LEDs, one for each removable, hot- swappable power supply. Each LED is located to the left of the power switch on the front panel for that supply. On the AC power supply for the ASX-200BX, the LED is green under normal circumstances, indicating that the 5-volt supply coming from that particular power supply is functioning properly.

CAUTION

If the power supply LED is red, the faulty supply should be turned off as soon as possible, using the single power switch which controls power to that supply. The problem should then be diagnosed and repaired. Please refer to Chapter 3, Hardware Maintenance Procedures, for details about how to hot-swap a power supply in the ASX-200BX.

1.2.8 ASX-1000 Common Equipment Card (CEC)

The CEC provided with the ASX-1000 performs several functions. Because each SCP contains an Ethernet port, a major function of the CEC is to provide a single, unified Ethernet port connection for all of the SCPs. The CEC is also responsible for monitoring the environmental conditions of the switch and reporting this information to the SCPs. Th e CEC reports conditions such as malfunctioning fans, overheated power supplies, and an overheated enclosure.

Two different CECs currently exist, model A and B. Both CECs operate in exactly the same way, and both are inserted/removed in the same way. The only difference between the model A and model B CEC is in the front panel labelling. On the model B card, component labels are read left to right with the CEC installed (vertically) in the switch . Also, the alarm relay contacts and alarm LEDs are labelled individually for easier identification.

1.2.8.1 CEC Front Panel

The front panel of the ASX-1000 CEC includes the following features: alarm relay contacts, CEC status LEDs, and an Ethernet port with four LEDS. These features are illustrated in Figure 1.13 (model A) and Figure 1.14 (model B). Refer to the following subsections for detailed descriptions of these features.

The LEDs for the two power supplies should be illuminated yellow, indicating that the CEC is on and that the power supply corresponding to that LED is functioning correctly. The LED for a failed power supply will be extinguished. On an ASX-1000, power supply “1” is in the slot labeled PS1 on the enclosure, while power supply “2” is in the slot la beled PS2 on the enclosure.

1.2.8.3.3 Switch Board LEDs

There are four switch board LEDs on the front panel of the CEC, one for each possible switch board. These LEDs should be blinking, indicating that the switch has booted and is operating correctly. If the SCP is removed, the LEDs may remain in a steady-on or steady-off state. Even if the SCP has booted correctly, the LEDs will n ot illuminate if the SCP is running a software version prior to ForeThought 3.2.0. If the switch board in the slot corresponding to the LED is not intended for an ASX-1000 (e.g., it is an ASX-200BX boar d), or if the entir e switch boar d corresponding to that LED is removed, then that LED will be extinguished. On an ASX-1000, the SW1 LED corresponds to switch board “1,” which is in the slot labeled 1 on the enclosure, and so on.

1.2.8.4 Ethernet Port

The Ethernet port located on the CEC of the ASX-1000 has a standard RJ-45 female connector and is designed to provide a single, unified Ethernet connection.

2.7 Modem Configuration

All ForeRunner ATM switches support modem access. This may be useful if a switch is installed in a remote location where direct, physical access to the switch is not possible or practical. Keep the following in mind when using a modem to access a ForeRunner AT M switch:

• To allow the ForeRunner ATM switch to communicate with the modem, a NullModem Adapter must be installed on the factory-supplied serial cable.

•The ForeRunner ATM switch will not disconnect an ATM Management Interface (AMI) session on loss-of-carrier; therefore, you must ensure that you have completely exited from an open AMI session before disconnecting the modem session.

The following two items apply ONLY to a

NOTE

• On an ASX-200 , do not attempt to send a <BREAK> character through the modem to the ASX-200. A <BREAK> character may force an abnormal halt of the ASX-200.

• On an ASX-20 0, power cycling a modem wh ile it is attached to the AS X-200 may force an abnormal halt of the switch.

ForeRunner ASX-200 ATM switch.

To allow a modem to work with a ForeRunner A TM switch, you must complete two sets of configurations. First, the speed of the serial port on the ForeRunner ATM switch must be set to match that of the attached modem and, second, the modem parameters must be configured correctly.

2.7.1 Serial Port Configuration for an ASX-200

The ASX-200 supports three modem speeds: 1200, 2400, and 9600 baud. To match the speed of the modem you have installed, log in to AMI on the switch. Enter the following parameters to change the serial port speed:

2.8 Configuring IP Addresses

The recommended configuration for a ForeRunner ATM switch is to assign an IP address to its network interfaces. This allows you to com municate with the switch from any workstation connected to your ATM LAN. IP addresses must be assigned to the network interfaces in order to perform any SNMP functions. Additionally, if you intend to connect the switch to an Ethernet, you should assign an IP address to the switch’s Ethernet network interface.

To configure the IP addresses, log in to an AMI session on the switch. To modify the IP address of the SCP’s IP interfaces, enter the following parameters:

3.1 Network Module Replacement

3.1.1 Overview

The network modules in all ForeRunner ATM switches are hot-swappable, meaning that they can be removed and replaced with the unit under power. Network modules should only be hot-swapped for purposes of replacing a failed unit. Therefore, they should be re placed w ith a network module of the same type, the same Series, and with the same number of ports. A network module’s type is the class to which the network module belongs (e.g., DS1, OC-3, E3, TAXI, etc.).

- Network Module Replacement

- Power Supply Replacement

- Fan Tray Replacement

- Switch Control Processor Replacement

- Switch Board Replacement

If a network module is removed and replaced by a network module of another type or by a network module with fewer ports, all configuration information for that network module’s slot will be deleted, and the new network module will be configured with the defaults for its type. For example, if a 4-port Series A OC-3c is replaced by a 4-port Series C OC-3c, the Series C network module will use the same configuration of the Series A network module. Any additional configurable variables will contain OC-3c defaults. If a 4-port OC-3c is replaced by a 4port DS1, all configuration information for that slot will be deleted and the DS1 will be initialized with DS1 defaults. If a 6-port DS1 is replaced by a 2-port DS1, all configuration information for the slot will be deleted, and the new DS1 initialized with DS1 defaults. If a network module is placed into a previously vacant slot, it will be initialized into the default state appropriate to that type of network module.

3.1.2 Multicast Mode

When hot-inserting or hot-swapping a network module, the mode in which the switch is running must also be considered. A ForeRunner 200 Series switch can operate in one of two multi- cast modes: extended mode or non-extended mode.

• Extended mode - The added features of Series C network modules give ForeRun- ner switches greater flexibility when choosing VCIs for multicast connections. This flexibility provides more successful multica st (point-to-multipoin t, or PMP) connection setups. If a switch fabric is empty or if it contains only Series LC network modules, the switch will operate in extended mode.

• Non-extended mode - If a switch fabric contains at least one Series A or B network module, that switch fabric will operate in non-extended (or mixed) mode.

Series A and B network modules can not operate

NOTE

in the same switch fabric as S eries LC network modules.

The mode in which the switch operates is determined each time the SCP restarts. If a switch is running in extended mode and a Series A or B network module is hot-inserted, the switch will not automatically revert to nonextended mode. The switch must be restarted immediately so that it operates in non-extended mode. If it is not restarted, all multicast connections fail on the Series A or B network module.

Series C or

You can display the multicast mode in which your switch is operating by using the configu- ration board show command in the ATM Management Interface (AMI).

If a switch is running in non-extended mode,

ATM Switch User’s Manual

Software Upgrade Instructions

4.3 Performing the Software Upgrade

The software upgrade is performed with the operation upgrade command in AMI. The underlying file transfer mechanism used in the upgrade is TFTP. TFTP can run in “secure” or “unsecure” mode, and it is assumed that your TFTP server is running in secure mode. Therefore, if TFTP is to run properly between, the file(s) being transferred must reside in the /tft- pboot directory on the source machine (see Section 4.7.4 for more information).

To perform an upgrade, the switch initiates a TFTP session with the specified host, which searches for the file requested. The host, which is running TFTP, looks for the file in /tftp- boot. The TFTP process on the server automatically appends “/tftpboot” to the path or filename specified by the client.

For example, issuing operation upgrade 169.144.3.54:asx-scp_4.1.0_1.3 will cause the TFTP server to locate and transfer the file /tftpboot/asx-scp_4.1.0_1.3. For this reason, it is imperative that you place the upgrade file in the /tftpboot directory on the workstation to which you downloaded or extracted the file. If this directory does not already exist, it is likely that T FTP is not running on the workstation. See S ection 4.7.4 for ins tructions on setting up a TFTP server and placing the upgrade file in the /tftpboot directory.

Once you have verified your TFTP server and placed the software upgrade file, you need to invoke the upgrade process on the SCP. Log in to AMI and enter the following parameters at the localhost::> prompt:

operation upgrade ?

localhost::operation flash> dir

FT400.35 CURRENT FT411.25

However, in this list,

CURRENT

is simply a pointer to the version that will be used as the current switch software during a reboot. To display the version to which well as all the versions that are installed, type the following:

localhost::operation> version Software versions installed : FT400.35 FT410.25 Current software version is FT400.35

Notice that no parameter for

version

was specified above. If no parameter is specified, it will

list the current and installed versions, but will not change anything. In this example, to change the current version of software from

FT400.35
