SYSTEM DESCRIPTION

PathBuilder S330/S310 Overview

PathBuilder S330

Features

This chapter describes the SuperStack® II PathBuilder® S330 and SuperStack® II PathBuilder PathBuilder S330 and PathBuilder S310 system speciﬁcations. It includes the following sections:

n PathBuilder S330/S310 Overview n Speciﬁcations n Options and Parts List

The PathBuilder S330 WAN access switch provides cost-effective T1/nxT1 or E1/nxE1 connections between local campus and enterprise networks via private leased line or public carrier ATM services so you can extend high-speed Internet access, Frame Relay, and ATM network service, as well as voice and video, out to your branch ofﬁces. Using the built-in ATM Forum standard-based inverse multiplexing capabilities, you can integrate voice, video, and high-speed data services over the same WAN link.

The PathBuilder S330 and PathBuilder S310 use basically the same hardware, with the PathBuilder S330 providing more interfaces. The following subsections describe the features of each unit in greater detail.

The PathBuilder S330 base platform offers the following features:

n T1/nxT1 ATM UNI or E1/nxE1 ATM UNI with up to four interfaces for

aggregated high-speed of 6Mbps WAN access. Each user-to-network interface (UNI) can be used alone or bundled into a group using the Inverse Multiplexing for ATM (IMA) standard, accommodating branch ofﬁce growth from a single T1/E1 (1.5/2 Mbps) bandwidth to four T1s/E1s (6/8 Mbps).

S310 WAN access switches (PathBuilder S330/S310), and lists

The PathBuilder S330 allows up to 70 msec of differential delay between T1s/E1s in a single IMA bundle. The unit also supports an automatic mechanism for removing failed lines from an IMA bundle, ensuring the resiliency required for your mission-critical applications.

n Multiple connections to Ethernet segments over ATM WAN and support of

bridging, including learning, aging, ﬁltering, and Spanning Tree, through the Ethernet module.

n Support of Frame Relay (service and network) interworking, ATM DXI, and

SDLC/HDLC pass-through, through the high-performance serial frame data interface.

4 CHAPTER 1: SYSTEM DESCRIPTION

n Choice of either single-mode or multi-mode OC3/STM-1 (separate units),

n Three expansion slots, allowing you to add other advanced features, such as

n 4x switch switching architecture, including four priority queues (three queues

The following optional modules are available for use with the PathBuilder S330:

n The four-port CBR module services trafﬁc generated by your existing PBXs,

through the OC3/STM-1 module. Single-mode enables higher-speed trunking if you have access to ﬁber WAN, while multi-mode is ideal for connecting high-speed servers, switches, or hubs equipped with multi-mode ﬁber connections.

channels, T1/E1 multiplexers, CSU/DSUs, and video conferencing devices. The CBR module consists of one V.35/RS-449 and three T1-DSX or E1 interfaces, which support both structured and unstructured services, in accordance with the ATM Forum’s Circuit Emulation Service (CES) speciﬁcations. The CBR module provides a smooth migration from legacy CBR service (PBX/voice/video) to ATM service. It also supports all relevant ATM and T1/E1 standards, ensuring easy integration of existing equipment into new ATM networks.

n The one-port Voice Compression module (VCM) is similar in function to the

CBR module, but it employs compression algorithms that allow more voice calls to be placed through the same bandwidth. The VCM’s T1-DSX/E1 interface connects to a PBX trunk, which may use CAS or CCS signaling. Its 24/31 DSO channels can carry individual voice, fax, modem, or data connections. You can also bundle multiple DSOs to provide connections for high-rate applications such as video conference or multiple-link PPP. For CCS, a DSO is used as an ISDN D-channel for carrying signal messages.

n The DS3/E3 module provides a DS3 or E3 interface, typically used for

terminating/accessing the public or private ATM WAN services. However, depending on your local applications, you can also use these modules for taking local DS3 or E3 ATM trafﬁc across the WAN.

Figure 1 shows the PathBuilder S330 with the optional CBR module installed in expansion slot 7, Voice Compression module in slot 8, and DS3/E3 UNI module in slot 9.

protocol, basic frame relay protocol (DLCI to VP/VC conversion), and transparent HDLC mode of operation

n Structured and unstructured CBR T1-DSX/E1 and V.35/RS-449/RS-530/X.21

interface

n Dynamic bandwidth allocation for structured voice CBR ports—stored signaling

bits are checked and bandwidth is released when an on-hook (idle) condition is detected

n RS-366-based video dial feature, supporting point-to-point and multi-point

video conferencing

n Voice compression, supporting voice activity detection, fax relay, DTMF relay,

and G.729A, G.726, and G.711 compression algorithms.

S330 Only n DS3/E3 UNI interface

n Local management via a VT100 terminal (or a PC emulating one) connected

directly to the PathBuilder S330/S310, or through a Telnet session.

n Software downloading via TFTP, FTP, or direct via RS232 n Built-in, menu-driven software for conﬁguring modules, ports, virtual circuits,

and bridges; setting loopbacks; and collecting and displaying alarms.

Key Beneﬁts The PathBuilder S330/S310 provides the following key beneﬁts:

n Complete integration into existing application environments by supporting

legacy data, video, and voice applications, thereby avoiding costly forklift upgrades.

n Video dial feature supports point-to-point and multi-point dialed video

conferencing over ATM networks, including:

n RS-366 video dial n Static call routing for all destinations n Ideal for video equipment such as H320 n Dynamic bandwidth allocation at both the V.35/RS-366 port and the

T1-DSX/E1 port on the CBR module

n Video session dialed through SNMP interface via Telnet and RS232 n Simulation of a switched ISDN network over an ATM network

S330 Only n Standards-based IMA implementation; the PathBuilder S330 offers T1/nxT1

and E1/nxE1 ATM access with up to four T1/E1 connections, allowing you to scale up WAN bandwidth as your trafﬁc increases. Each user-to-network interface (UNI) can be used alone or bundled into a group, providing up to 6/8 Mbps aggregated WAN access speed.

8 CHAPTER 1: SYSTEM DESCRIPTION

n Easily upgradable; no additional hardware required to move from the

PathBuilder S310 to the PathBuilder S330; update your system simply by purchasing a software upgrade.

n A sophisticated trafﬁc management system allows management of a mix of

applications simultaneously, with features such as deep buffers, trafﬁc shaping, QoS (Quality of Service), and early packet discard, to give you the most effective wide-area ATM bandwidth use and ensure applications integrity.

n Embedded management includes a full IP stack (Telnet, TFTP, and SNMP) and

ﬂash memory for sophisticated yet simple network management.

n Comprehensive feature support, including resiliency of nxT1/E1 IMA (S330

only) and redundant power for protection against power failure, ensures maximum application and network uptime.

n 3Com SuperStack II compliance provides common look and feel hardware and

integrated network management solutions.

n 3Com SuperStack II Redundant Power Supply (RPS).

Figure 13 Replacing the PathBuilder S330/S310 Cover

Step 2: Install the Unit in

the Rack

b Secure the cover with the eight assembly screws you removed in step 1a.

In a normal rack mount conﬁguration the PathBuilder S330/S310 shelf is 3.5" x 17" x 15.5" including cables. Since the equipment is cooled with two internal fans, clearance at the top is not needed; however, convection cooled equipment must not be mounted directly under the shelf.Allow at least one rack unit clearance below the unit. See Figure 14 for details. If the PathBuilder S330/S310 is mounted in an enclosure, plan on enough clearance at the front for cable and wiring service loops.

CAUTION: Many of the integrated circuits on the modules are sensitive to static electricity. Do not handle the plug-in modules without wearing a properly grounded antistatic, wrist strap. When removing the modules from the shelf, place them printed-circuit side down on a nonconducting, static-free, ﬂat surface.

To mount the shelf, follow these steps:

1 Attach the rack-mount ears to the unit, following the instructions supplied with

the ears.

CAUTION: When attaching the rack-mount ears, you must use the factory-supplied screws. Using screws other than those supplied with the rack-mount ears voids your warranty and could damage the PCB.

2 Adjust the rack-mount ears if necessary for 19" installation. See Figure 14.

CAUTION: Do not block the ventilation openings on the top and bottom of the unit during installation. A minimum of 1 rack unit (1.75”) space is required.

If you are using a G703 coax physical connection to connect the E1 line to the interface, you must use the E1 Balun Adapter (part number 3C63904).

The serial port of the PathBuilder S330/S310 CBR module has two types of interface: V.35 for video data and RS-366 for video dial. These interfaces are broken out from a 50-pin connector on the S330/S310 via a Y cable. Use the V.35/RS-366 serial CBR connector to connect directly to H.320 video codec devices such as PictureTel, Vtel, and CLI.

ALM INS

The DS3/E3 UNI shares the same queue (Queue 1) as the Group 1 IMA UNI; therefore, if a DS3/E3 expansion card is installed in slot 9, the system deletes Group 1 and all corresponding VCs on startup and generates an information only alarm. Furthermore, you cannot add Group 1 if a DS3/E3 expansion card is installed—either in the chassis or in the database. If you change the card type for slot 9 to DS3/E3 via the List Card menu, Group 1 and the corresponding VCs are not deleted until the system is restarted.

In order to conﬁgure application connections and an IP address for SNMP support, you must connect a management terminal to the PathBuilder S330/S310. To do this, follow these steps:

1 Connect a VT 100 terminal to the RS-232 (console) port on the front of the

PathBuilder S330/S310.

2 Use the VT100 terminal to input an IP address for the PathBuilder S330/S310. See

“Setting up Communication Parameters” in Chapter 3 for details.

3 Establish communication between the PathBuilder S330/S310 and any

management terminal in one of these ways:

n Direct RS-232 using the VT100 terminal or VT100 emulator, as described above n Direct 10BaseT on the Management CPU card using an IP Telnet session

S330/S310 and can make changes to the system.

n Read Only means that you can only monitor the menus and displays.

Only one Read/Write session is allowed at any given time. The ﬁrst session is the Read/Write session. Subsequent simultaneous sessions are Read Only.

Navigating through the

Menus

Understanding the

Menu Hierarchy

You select a menu option by typing the selection number and pressing [Enter]. Displays that contain information and no selections include the prompt:

Press Esc for previous menu

Multi-page displays also prompt you to press “N” for the next page or “P” for the previous page.

Only the Main menu contains the Exit selection to log out. Selecting Exit returns you to the title screen with the password prompt. All other menus have a Previous menu selection which returns you to the Main menu one screen at a time. You can also press [Esc] to move back one menu at a time.

The auto logout feature automatically logs you out and returns you to the title screen if you do not press a key for a speciﬁed time (1 - 99 minutes). To set the autolog timeout, select [1] System Administration from the Main menu, then select [1] General System Information, then select [6] Set Auto Logout Time.

Always return to the Main Menu to log out or let the auto logout time expire. Exiting the program in any other way, such as turning power off to the network management station, may cause unpredictable results.

The PathBuilder S330/S310 menu hierarchy includes several layers of menus. Each submenu has a name that is the same or similar to the name of the option that displays it. For example, selecting [2] Conﬁguration Management on the Main Menu displays a submenu titled Conﬁguration Management, and selecting [4] Manage System Clock from the System Administration menu displays a submenu titled System Clock Conﬁguration. You can then select options on the submenus to display additional submenus or prompts that allow you to set various parameters.

62 CHAPTER 3: GETTING STARTED

Using the Menus to

Change Settings

Settings are displayed in prompts at the bottom of the menus. For example, if you select

[2] Conﬁguration Management [1] Manage Card [4] OC3/STM-1 UNI [3] Set ATM Payload Scramble

The following prompt appears at the bottom of the SONET/STM-1 UNI Conﬁguration menu:

Enter ATM Payload Scramble (1=No,2=Yes):

When you type a selection number and press [Enter], payload scrambling is disabled or enabled and the prompt is cleared.

Alarm Indicator If the PathBuilder S330/S310 detects an alarm condition, an alarm indicator (the

highlighted word “Alarm”) appears to the left of the access status on every menu and display, as shown in Figure 32.

Figure 32 Alarm Indicator

indicates that an alarm condition

has been detected

After you acknowledge the alarm, the alarm indicator is no longer highlighted, but the word “Alarm” remains in the upper right corner of the screen to indicate that an alarm has been acknowledged.

When the alarm is acknowledged and the condition that caused the alarm is cleared, the indicator disappears entirely. If a menu indicates that an alarm has been acknowledged and a new alarm occurs, the Alarm indicator is highlighted again.

See “Managing System Alarms” in Chapter 5, for instructions on acknowledging alarms.

Performing Initial System Configuration 63

Performing Initial System Conﬁguration

After you install the PathBuilder S330/S310 hardware, you must complete the following three steps in order to put the unit into operation:

1 Conﬁgure the system clock 2 Set up communication parameters 3 Set the time and date 4 Set up passwords

You access the menus used to perform these steps from the System Administration menu, shown in Figure 33. To display the System Administration menu:

From the Main menu, select [1] System Administration.

Figure 33 System Administration Menu

Conﬁguring the System

Clock

The following subsections provide instructions for performing the four initial conﬁguration steps. See Chapter 4 for instructions on conﬁguring speciﬁc PathBuilder S330/S310 ports and modules.

By default, the PathBuilder S330/S310 uses the internal clock as its reference clock. You can specify up to eight additional clocks for the system to use as a reference clock. When you set the clocks, you also assign each one a priority. You can then set the system clock to the clock with the highest priority. If this clock fails, the system automatically uses the clock with the next highest priority as its reference clock. It defaults to the internal clock only if all eight clocks fail or if there are no more valid selections.

64 CHAPTER 3: GETTING STARTED

1 From the System Administration menu, select [4] Manage System Clock to display

To set system clocks, follow these steps:

the priority 1 (highest priority) clock.

3 Enter the option number corresponding to the clock you want to designate as the

priority 1 system clock. The clock options correspond to the available ports.

If you are conﬁguring a PathBuilder S310, do not select unavailable ports (ports 2-4, CBR ports 2 and 3, and OC3/STM-1) as system clocks—even though the software lists these ports and allows you to select them.

4 Repeat steps 2 and 3 to designate up to seven additional clocks as the priority 2

through 8 clocks, substituting the appropriate option in step 2. For example, to designate the priority 2 clock, select [4] Set PriorityClock 2.

5 Select [11] Set System Clock to Highest PriorityClock to set the system clock to the

clock you designated as the priority 1 clock in step 3 above. If this clock fails, the PathBuilder S330/S310 will automatically use the clock with the next highest priority as its reference clock.

In order for the PathBuilder S330/S310 to communicate to the Ethernet network, you must set the correct communication parameters. To do this, select [3] Manage IP Network Conﬁguration From the System Administration menu, to display the Manage IP Network Conﬁguration menu, shown in Figure 35, and conﬁgure the following:

Figure 48 Report Firmware Version Screen

78 CHAPTER 4: CONFIGURING PATHBUILDER S330/S310 MODULES, PORTS, AND APPLICATIONS

The Report Firmware Version screen displays the following information about the management processor active ﬁrmware (the upgradeable ﬁrmware currently being used by the MCPU):

Version—The released ﬁrmware version number. This is the version number that is displayed on the login screen.

Origins—The original engineering build number for the release.

If the Version and Origins release numbers are the same, then the release is not an ofﬁcial release but rather a Beta test version.

Who—The user login ID for this software build. Date—The date and time that the build was made. Company Name—3Com Corporation (or OEM partner if desired) Product Name—The PathBuilder product for which this image was built:

PathBuilder S700, PathBuilder S600, PathBuilder S330, or PathBuilder S310.

In addition to the management processor ﬁrmware information listed above, the Report Firmware Version screen also lists the Boot Firmware Release—the version number of the boot ﬁrmware containing the bootstrap code used to bring up the operation ﬁrmware.)

Downloading New

Management Processor

Firmware

The PathBuilder S330/S310 module retains the operation ﬁrmware in a ﬂash memory bank located in the motherboard. On power-up or reset, the code image is copied from the ﬂash memory to the main memory.

The ﬂash memory retains a copy of the operation ﬁrmware and can be upgraded using TFTP or the Xmodem protocol. TFTP is used if you are attached over the Ethernet interface through a Telnet session. Xmodem is used if you are attached to serial port 1 on a VT100 terminal.

We recommend that you avoid using the serial interfaces unless the Ethernet interface is unavailable, as a download could take 30 minutes at 9600 baud using the serial interfaces.

When downloading, the ﬂash memory is overwritten with the new code. Once the ﬁrmware is successfully downloaded, a system reset brings up the new code.

The following instructions pertain to UNIX environments. You can also download ﬁrmware from a PC: from a TFTP application, conﬁgure for binary mode, specify the location of the image ﬁles, and use the PUT command.

Viewing and Configuring System Information 79

Downloading via the Ethernet Port

To download new ﬁrmware using TFTP, via the Ethernet port, follow these steps:

Be sure to log in via Telnet. If you log in at a serial port, the download sequence will attempt an Xmodem rather than a TFTP download.

1 Obtain the correct image ﬁle location and name from 3Com Customer Service. 2 Telnet into the PathBuilder S330/S310 unit. 3 From the System Administration menu, select [7] Download Firmware. The

following prompt appears:

This action will erase the flash memory Do you want to download firmware (Y/N) [N]?

4 Enter y and wait for the Ready to download... message. 5 From a workstation or PC (typically the same one doing the Telnet), invoke TFTP

using the PathBuilder S330/S310 IP address. From TFTP do:

binary put image.abs

where image.abs is the ﬁlename of the image ﬁle to download)

The download will complete in about two minutes (over lightly loaded Ethernet). The TFTP should indicate that the ﬁle is transferred, and the Telnet screen should display “download complete.”

Downloading via the Serial Port

To download new ﬁrmware using the Xmodem protocol, via the serial port, follow these steps:

You must use a terminal emulation program that supports Xmodem protocol.

1 Obtain the correct image ﬁle location and name from 3Com Customer Service. 2 Log into the PathBuilder S330/S310 unit through a serial port. 3 From the System Administration menu, select [7] Download Firmware. The

following prompt appears:

This action will erase the flash memory Do you want to download firmware (Y/N) [N]?

4 Enter y. The PathBuilder S330/S310 unit assumes that an Xmodem download is to

be done and looks for that protocol over the serial port. Once the unit has erased the ﬂash memory, a message on the screen indicates that the unit is ready to accept an Xmodem download.

5 On the terminal emulation prompt, select Xmodem protocol and input the ﬁle

name of the binary ﬁle to be downloaded.

The typical download time at 9600 baud is greater than 30 minutes.

Updating the Flash File

System

Resetting the Interface

Card

The ﬂash ﬁle system contains system conﬁguration information which is automatically saved in ﬂash memory at a predetermined interval. To update the ﬂash ﬁle system immediately, rather than at the next scheduled interval, follow these steps:

1 From the System Administration menu, select [8] Update Flash File System. The

following prompt appears:

Do you want to update the flash file system (Y/N) [N]?

2 Enter y to update the ﬂash ﬁle system.

CAUTION: The user conﬁguration data is automatically saved into ﬂash memory every minute. If there is a system failure (for example. a power failure), any changes that you make during the auto-saving interval will be lost. Thus, we recommend that you use the [8] Update Flash File System option, as described above, immediately after you make major conﬁguration changes.

The PathBuilder S330/S310 software allows you to reset only the MCPU interface card and the Voice Compression module (VCM) card. Resetting the MCPU reboots the system. To reset the MCPU interface card or the VCM card, follow these steps:

If you reset the MCPU interface card, you will terminate your Telnet session.

1 From the System Administration menu, select [9] Reset Interface Card. You are

prompted to select the card you want to reset.

Conﬁguring MCPU

Shapers

To view conﬁguration information for the management CPU:

From the MCPU Conﬁguration menu, select [1] Card Conﬁguration to open the Management Processor Conﬁguration screen. This screen displays the following CPU conﬁguration information:

n Hardware revision n Serial number n Status (In Service or Out of Service)

The PathBuilder S330/S310 supports three MCPU shapers parameters:

n Peak Cell Rate (PCR)—The maximum rate that can be passed. n Sustained Cell Rate (SCR)—The maximum average rate that a bursty, on-off

trafﬁc source can send; used in conjunction with maximum burst size.

n Maximum Burst Size (MBS)—The maximum number of cells that can be sent

at the peak rate; used in conjunction with sustained cell rate.

Using the MCPU Shapers screen, shown below in Figure 53, you can conﬁgure up to 15 shapers. The values that you set for the shapers on this screen are the values that are then available for the Shaper Number parameter that you set when you conﬁgure certain types of virtual circuits. See “Common VIrtual Circuit Parameters” later in this chapter for details.

How you conﬁgure the MCPU shapers depends on the type of service you have.

n If you have a peak rate service:

n Set the peak rate at the maximum allowable value. n Set the sustained cell rate at the same rate as the peak rate.

n If you have a sustained rate service:

n Set the peak rate at the line rate (for example 45Mbps for a DS3 line). n Set the sustained cell rate and maximum burst rate at the values given to

you by your service provider.

84 CHAPTER 4: CONFIGURING PATHBUILDER S330/S310 MODULES, PORTS, AND APPLICATIONS

CAUTION: When assigning shapers for VCM circuits, be sure that the shapers are wider than the bandwidth used for the voice trafﬁc.

To conﬁgure the MCPU shapers, follow these steps:

1 From the MCPU Card menu, shown in Figure 52, select [2] Shaper Conﬁguration

to display the MCPU Shaper screen, shown in Figure 53. The MCPU Shaper screen consists of a table listing the current shaper values in

bits/second (bits for the maximum burst size shaper) and cells/second (cells for the maximum burst size shaper). Initially, the shapers are set to default values.

Figure 53 MCPU Shaper Screen

2 To enter a new shaper value, use the arrow keys on your keyboard to move to the

cell in the shaper table that you want to change.

n To set a new Sustainable Cell Rate or Peak Cell Rate shaper, enter the new

value in the bits/second (bps) column. The system automatically calculates the cells/second (cps) based on the value you enter.

n To set a new Maximum Burst Size shaper, enter the new value in the cells

column. The system automatically calculates the bits based on the value you enter.

Configuring the CTX 85

Conﬁguring the CTX CTX conﬁguration involves managing buffers and managing shapers. To display

the CTX Menu, follow these steps:

1 From the Conﬁguration Management menu, in Figure 50, select [1] Manage Card

to display the List Card menu, shown earlier in Figure 51.

2 Select [2] CTX to display the CTX menu, shown in Figure 54.

Figure 54 CTX Menu

Conﬁguring CTX

Shapers

From the CTX menu, you access the submenus and screens from which you perform buffer and shaper conﬁguration, as described in the following subsections.

The PathBuilder S330/S310 supports ten peak rate shapers. The shapers are separated into ten virtual queue-trunks:

n 4 for the group 1 IMA WAN interface:

n Trunk bulk n medium n low1 n low2

n 2 for the AAL5 SAR (Ethernet and V.35/RS-449 packet)

n SAR output n SAR input

CAUTION: The default conﬁguration is optimized for performance.

n 4 for the OC3/STM-1 interface:

n OC3/STM-1 bulk (MMF or SMF) n OC3/STM-1 queue 1 n OC3/STM-1 queue 2 n OC3/STM-1 queue 3 n OC3/STM-1 queue 4

86 CHAPTER 4: CONFIGURING PATHBUILDER S330/S310 MODULES, PORTS, AND APPLICATIONS

You can assign shapers for these queue-trunks based on peak rate (or bulk shaping) towards the WAN. To do this, follow these steps:

1 From the Conﬁguration Management menu, select [1] Manage Card to display the

List Card menu.

2 Select [2] CTX to display the CTX menu, shown in Figure 54. 3 From the CTX menu, select [1] Manage Shapers. The CTX Shapers menu appears,

as shown in Figure 55.

Figure 55 CTX Shapers Menu

4 Select the number corresponding to the shaper you want to conﬁgure. A prompt

appears similar to the following:

Enter cells/sec, (150..195 312K)

5 Enter the desired shaper value.

Conﬁguring CTX Buffers The CTX is an output-buffered switch, with a 64K cell buffer capacity. The

software sets up a default conﬁguration, but you can change it if you want. For example, you should make the queue (buffer) used for your router trafﬁc as large as possible. To do this, you must ﬁrst deallocate memory from another queue—OC3/STM-1 queue 3, for example—and reallocate the memory to the queue that will carry your router trafﬁc. See “CTX Output Queues and Memory Partition” in Appendix B, for reference information pertaining to conﬁguring the output buffers.

To change the default output buffer conﬁguration, follow these steps:

1 From the Conﬁguration Management menu, select [1] Manage Card to display the

List Card menu.

2 Select [2] CTX to display the CTX menu, shown above in Figure 54. 3 From the CTX menu, select [2] Manage Buffers. The CTX Buffers menu, shown in

Figure 56, appears.

Configuring the CTX 87

Figure 56 CTX Buffers Menu

4 Select the number corresponding to the queue for which you want to change the

buffer size. The CTX Queue Buffer Conﬁguration menu, shown in Figure 57, appears. This menu lists the current buffer conﬁguration for the selected queue and provides options that allow you to change the buffer size and set congestion thresholds.

Figure 57 Conﬁguring CTX Buffers and Congestion Thresholds

5 Select [1] Set Buffer Size. The following prompt appears:

Enter Buffer Size (768..62580 cells):

6 Enter the desired buffer size, in cells (256 cells = 1 block). 7 Use the [2] Set Congestion On and/or [3] Set Congestion Off options to change

the default congestion thresholds.

88 CHAPTER 4: CONFIGURING PATHBUILDER S330/S310 MODULES, PORTS, AND APPLICATIONS

When you select one of these options, a prompt appears at the bottom of the screen, allowing you to enter a new threshold in the range 0% to 100%. When the buffer reaches the Congestion On threshold, the congestion ﬁlter is on. When the buffer falls below the Congestion Off threshold, the congestion ﬁlter is off.

For example, if you set Congestion On to 75% and Congestion Off to 50%, the congestion ﬁlter is on when the buffer is 75% full and is off when the buffer drops below 50% full.

See “Setting Congestion Thresholds” below for further details about congestion thresholds.

CAUTION: You should enable early packet discard for AAL5 trafﬁc only.

8 Select [4] Previous Menu to return to the CTX Buffers menu. 9 Press [Esc] to return to the CTX menu.

10 Select [3] Apply CTX Buffer Changes to apply your settings.

CAUTION: This operation will affect trafﬁc.

Setting Congestion Thresholds

For every connection where early packet discard is enabled, a status is kept when there is a partial packet for that connection in the queue. Once the queue cell level exceeds the Congestion On thresholds, only connections with partial packets already existing in the queue are allowed in. Cells from other connections are dropped. Once the congestion has subsided to the Congestion Off level, then all remaining connections are allowed.

Set the Congestion On threshold based on the maximum packet size expected and the number of active connections sending packets at a particular instant based on a probability model.

Set the Congestion On level to allow some hysteresis in the operation.

Conﬁguring Ports The PathBuilder S330/S310 ports each have an administrative and an operational

status. To set up a virtual circuit, you must ﬁrst set the administrative status of the port which will carry the circuit online to In Service. You can also conﬁgure other parameters, depending on the type of port.

When you set the administrative status to Out of Service, the operational status is set to Out of Service whether or not the port is actually operational or not. Once you set the administrative status to In Service (online), the operational status will indicate the true port status (Out of Service if there is a port failure, or In Service if not).

The following sections tell you how to conﬁgure speciﬁc ports on the PathBuilder S330/S310.
