Cajun P550/P220 Switch Operation Guide xii

Preface

This guide explains how to configure and operate the Lucent P550, P550R, P220G, and

P220FE Cajun switches. The P220 Cajun switch family contains Layer 2 functionality

only, while the P550 contains both Layer 2 and Layer 3 functionality. Therefore, all

references to Layer 2 functionality apply to both the P220 Cajun switch family, as well as

the P550 Layer 2 switches.

This guide also includes information on downloading new operational code to your

switch. For detailed information on the command line interface, refer to

Preface

Installing Online Documentation and Help Files

Certain resources used by the Web Agent are located off the switch to preserve switch

memory. Setting up a help server location for the switch allows the switch to access:

❒ Online documentation ❒ Bitmaps used as part of the interface (logo, wallpaper) ❒ Online help files for the Web Agent

There are two ways to provide this information to the switch:

❒ Install the Lucent HTTP documentation server (available on the Lucent user

documentation CD, CajunDocs)

❒ Add the files to an existing web server on your network

Installing the Lucent HTTP Documentation Server

Lucent provides HTTP server software that you can install to provide access to

documentation and online help directly from the switch. The server must be running a

Win32 compatible operating system (for example, Windows 95, Windows 98, or

Windows NT).

To install the server, you must perform one of the following:

❒ Run the ❒ Click on the latest released version of the CajunDocs CD from the Lucent

Publications web site (http://pubs.lucentctc.com/cdrom/cajundocs.html) and double-click server machine and drive.

If you decide to install your online help on a Web server other than the Lucent HTTP server bundled on the CajunDocs CD-ROM, then specify the URL without a port number if your Web server runs on port 80 (for example, http://www.abc-company.com). If your Web server does not run on port 80, you need to add the port number (for example, http://host/path:port).

For example, if you transfer the CajunDocs help directory to your company server (http://www.abc-company.com) you would need to:

1. Install the online help and documentation from the CajunDocs CD to a Windows95 or NT node in your network.

2. Transfer the entire help subdirectory located in C:\CajunDocs to the root directory of your Web server.

3. Launch your browser and connect to your switch.

4. Enter your user name and password at the respective prompts and click Login.

5. In the System Configuration section of the Web Agent window, click Server Location. The Online Help Configuration dialog box opens.

6. In the HTTP Server Location field, enter the server location (for example,

http://www.abc-company.com).

7. In the HELP Directory Location field, enter the directory name of your help files. For example, help.

Note: The default for the help directory is help. You do not need to change this

unless you changed the name of your help directory prior to transferring it to your Web server.

Downloading an Updated CajunDocs CD from the Internet

The server and help files are available on the Internet. To download update your CajunDocs CD:

1. Launch a web browser and go to the CajunDocs Installer Web page at:

http://pubs.lucentctc.com/cdrom/cajundocs.html

2. Click the latest version CajunDocs CD-ROM installer to download into the directory you previously created.

The supervisor module is responsible for address learning, address cache management, and spanning tree management.

In addition, the Layer 3 supervisor module:

❒ Implements system management functions and management interfaces. ❒ Uses standard routing protocols and maintains routing table and caches. ❒ Provides 1.5 million packets per second of hardware-based routing for packets that

arrive on Layer 2-only media modules.

❒ Supplies software-based routing for packets that are not routed in hardware. ❒ Supports implementation of AppleTalk, and DECnet, that are not implemented in

hardware.

The Layer 3 supervisor module requires a faster CPU and more memory. Also unlike the Layer 2 supervisor, the Layer 3 supervisor is part of the path that some packets take through the system. To accomplish this, the Layer 3 supervisor requires faster data transfer to and from the switching fabric.

Crossbar

Port 13

Crossbars are more scalable than shared memory architectures. Architecturally, you can add more capacity simply by adding more switch elements. By comparison, shared memory switches have an inherent maximum upper boundary in throughput that makes high-density, single-backplane gigabit switches impractical. With a crossbar architecture you increase the number of gigabit ports in your network and the architecture scales to meet your needs.

The crossbar supports:

❒ 13 fabric ports (two per I/O module slot, plus one for the Supervisor Module). ❒ 1.76 Gbps (in and out) on each fabric port. ❒ 22.88 Gbps total capacity, 45.76 Gbps total backplane capacity. ❒ Under-subscribed switching fabric in most configurations (two connections per I/O

module slot, plus one for the supervisor module).

❒ Single copy replication - When possible, input frames destined for output multiple

switch ports pass through the crossbar only once and are copied by the crossbar to each destination.

❒ Hardware-assisted multicast pruning - The switch only forwards to appropriate

destination switch ports.

1-6 Cajun P550/P220 Switch Operation Guide

Cajun Routing Overview

The Cajun switch is an IP and IPX router with virtual interfaces. Virtual interfaces are mapped to physical ports or VLANs. Layer 3 IP traffic is routed between the virtual interfaces.

Ports become members of VLANs by assignment or by rules. Multiple VLANs can share a single trunk port. In contrast, multiple physical ports can be associated with a single VLAN. In all cases, traffic that arrives and leaves the same VLAN is bridged, not routed.

This section provides additional information that includes:

❒ Compatibility with the Layer 2 Switch ❒ Routing with Layer 2 and Layer 3 Modules

Compatibility with the Layer 2 Switch

The switch is completely backwards compatible with all of the Layer 2 media modules currently supported in the Cajun switch. Traffic from the Layer 2 media module is routed by sending that traffic to the routing engine on the Layer 3 supervisor module. The supervisor module routes all traffic from Layer 2 media modules in software as described in the section, “Routing with Layer 2 and Layer 3 Modules”.

Cajun P550 Switch Overview

Note: Layer 2 traffic that does not require routing is bridged independently of the

Layer 3 traffic based on the MAC address or VLAN information.

Routing with Layer 2 and Layer 3 Modules

When the Cajun switch is configured with a mix of Layer 2 and Layer 3 modules, IP and IPX routing is performed by the Layer 3 media module or the Layer 3 supervisor module using special ASICs present on those modules. These ASICs contain an address cache (forwarding table) that can hold a maximum of 20,000 address cache entries. The entries consist of packet addressing information and next hop information that enable the switch to effectively route the packets to their destination.

The Layer 3 supervisor also maintains a master routing table. The master routing table contains up to 24,000 entries. This routing table enables the supervisor module to keep track of which entries are in each address cache. As a result, each time a change occurs in the master routing table, the Layer 3 supervisor module updates the appropriate address caches. For example, if a unicast route is removed from the master routing table, then all matching entries in forwarding tables are removed as well.

Cajun P550/P220 Switch Operation Guide 1-7

Cajun P550 Switch Overview

Consequently, when you connect a Cajun switch to the network, it begins to receive frames from the network and builds a master routing table in the supervisor module and forwarding tables in each media module based on those frames.

This process creates three distinct results:

❒ All known (learned) traffic from Layer 3 modules that requires routing is routed

directly in hardware by the Layer 3 media module without a need to traverse the switching fabric to get to the supervisor module’s software routing function.

❒ All unknown (not learned) traffic from Layer 3 modules must first be sent to the

Layer 3 supervisor module, where information on the frame is added to the supervisor module’s master routing table and added to the appropriate address caches of Layer 3 media modules.

❒ Since Layer 2 modules have no routing capability, packets that are received by a

Layer 2 module and require routing are routed by sending the packet to the Layer 3 supervisor module. The routing engine on the supervisor module then performs the routing operation for the Layer 2 modules and sends the packet back through the switching fabric to the destination port.

Figure 1-4 shows a conceptual example of how traffic is routed in a Cajun switch.

Virtual Bridging Functions

The switch design supports:

❒ Up to 24,000 MAC addresses in the switch address forwarding table - This feature

allows the switch to store forwarding information for hosts in very large networks.

❒ Segmented address tables qualified by address and VLAN membership - This

feature allows the same host to appear on different VLANs on different ports.

1-8 Cajun P550/P220 Switch Operation Guide

Optional per-VLAN spanning tree - This isolates loop control to smaller domains, so

❒

spanning trees converge faster after a topology change. Otherwise, packets are forwarded to the port’s default VLAN.

VLAN Functions

A VLAN (Virtual LAN) is a logical group of hosts on a local area network (LAN) that communicate as if they were on the same wire, even though they are physically on different LAN segments throughout a site.

Virtual LANs provide network managers with two significant capabilities:

The ability to segment traffic in a flat switched network. This helps prevent traffic

❒

from being forwarded to stations where it is not needed.

The ability to ignore physical switch locations when creating workgroups. VLANs

❒

are logical constructions and can traverse physical switch boundaries.

The switch hardware supports Layer 1, Layer 2, and Layer 3 VLANs. The switch-based VLANs have the following characteristics:

Cajun P550 Switch Overview

Frames classified as they enter the switch using Layer 1 (Port-based).

❒

Explicitly-tagged VLAN packets are forwarded based on the information in the

❒

packet.

VLANs define a set of ports in a flooding domain. Packets that need to be flooded

❒

are sent only to ports participating in that VLAN (Figure 1-5).

Hunt Groups

Hunt groups (also known as link aggregation) aggregate bandwidth from multiple ports so they act as one high-bandwidth switch port. The concept used is borrowed from the world of telephony, where incoming calls to a single phone number are routed to the first available line. Hunt groups allow you to create multi-gigabit pipes to transport traffic through the highest traffic areas of your network.

A hunt group provides:

Inter-operation with other vendor’s equipment (for example, Cisco’s Etherchannel

❒

and Sun’s Quad Adapter).

Shared traffic load.

❒

Destination address-based traffic sorting, which keeps packets in the right order.

❒

Fault tolerance. If a port in a group fails, the remaining ports in the group pick up

❒

the traffic load.

Support for any number of same-speed connections in a group.

❒

Faster recovery from link failure: If a port in the group fails, the remaining ports

❒

can carry the load. Recovery not limited by spanning tree convergence time (convergence time is the time the network takes to resume steady-state forwarding after spanning tree reconfiguration).

Up to ten groups per switch.

OpenTrunk Technology

OpenTrunk technology translates VLAN-tagged frames from one format to another (including CoS).

The switch is delivered as a plug-and-play IEEE 802.1D standard bridge, but supports several VLAN tagging schemes. This makes the switch highly interoperable in existing networks because:

Any port can be a trunk port.

❒

Ports have configurable VLAN tagging on a per-port basis.

❒

Ports process a number of popular VLAN tagging schemes, including major

Extensive Fault Tolerance

The Cajun P550 switch is designed as a backbone switch. You can install the switch in your network’s core without creating a single point of failure.

Extensive fault tolerance features include:

❒ N+1 power. Power supplies share the power supply load. If a power supply fails,

the remaining supply or supplies assume the load automatically and the switch management system warns you of the failure.

❒ Hot-swappable power supplies, fans, and modules - Each can be changed from the

switch front panel, without powering down the switch.

Cajun P550 Switch Overview

Buffer and Queue Management

Adding gigabit speeds to existing networks means that there can be a huge disparity between link speeds. For example, anything more than a 1% load on a gigabit link could easily overwhelm a 10 Mb/s Ethernet link.

Without queue and buffer management, gigabit links might only move congestion in a network, rather than relieving it. The switch employs the following buffer and queue management techniques:

❒ Configurable active backpressure:

• Half-duplex ports use active backpressure to jam input ports when their frame buffers are full.

• Full-duplex links use IEEE 802.3z pause control frames to pause traffic when buffers are full.

❒ Packed frame buffers for optimal memory utilization. The memory management

allows virtually 100% utilization of buffer memory.

❒ Two Class of Service priority queues that provide flexible queue management

algorithms to meet application requirements.

❒ Large buffer space:

• 512 KB per gigabit port.

• 128 KB additional for outbound 10/100 ports.

❒ Configurable queue depth for each of two prioritized packet queues. ❒ Configurable priority threshold.

Web-Based Management

Web-based management allows you to manage switches from any station connected to your network.

The switch offers a command line interface and a rich set of web-based management features:

❒ Reduced Instruction Set Computing- based (RISC) Supervisor provides high-speed

VLAN, RMON, and network management support.

❒ Web Agent: Built-in SNMP and HTML-based agent, compatible with popular Web

browsers, provides top-to-bottom switch management.

Smart Agent

Smart Agent, the software for the Supervisor Module, has the following features:

❒ Built-in support for Simple Network Management Protocol (SNMP) and HTML ❒ Out-of-band from 10Base-T or RS-232 ❒ In-band from a defined VLAN ❒ Powerful alarm and event logging subsystem ❒ Point and click interface with Netscape Navigator V3.0 or later or Microsoft

Internet Explorer V3.0 or later

Cajun P550 Switch Modules

The Layer 2 and Layer 3 supervisor and media modules implement wire speed routing and bridging in Application-Specific Integrated Circuits (ASICs). One set of ASICs supports a gigabit-per-second’s worth of traffic (any combination of Layer 2 and Layer

3). The routing and bridging ASICs can process 1.5 million packets per second, which is just slightly more than a gigabit’s worth of minimum-sized Ethernet frames.

Configuring the Supervisor Module Using the CLI

To connect to the Web Agent, you must first use the serial command line interface (CLI) to give the supervisor module an IP address and a subnetwork mask.

Cajun P550/P220 Switch Operation Guide 3-1

Configuring the Cajun P550 Switch (Layer 2 & Layer 3)

To configure the supervisor module using the CLI:

Attach a

serial cable

from your PC’s serial port to the serial port of the supervisor module front panel (refer to Figure 3-1) using a 9-pin straight-through male-to-female serial cable (refer to “Switch Features,” earlier in this guide for pinout information).

Run a terminal emulation program (HyperTerminal, for example) on the attached PC. Ensure that the terminal settings match those listed in Table 3-1.

Power up the switch by turning on the power supplies. In the terminal emulation program, the switch displays the following startup messages:

Configuring the Cajun P550 Switch (Layer 2 & Layer 3)

Table 3-5 describes the Fast Ethernet port parameters:

Tab le 3 -5. Fast Ethernet (10/100) Port Parameters

Parameter Definition

Name A user-assigned name for this port (possibly a drop name or the

name of the station or other device connected to the port).

Category Allows you to select either User Port or Service Port.

• The User Port is intended for use with switch connections to end user nodes.

• The Service Port is intended for use with switch connections to servers or other switches. The Service Port allows the switch to generate both log messages and alarm messages (traps). The User Port only generates log messages, preventing your network management station from being overwhelmed by port up/down messages that result from users turning workstations on and off.

Speed Mode Allows you to select the speed of the port manually (to either 10

or 100 Mb/s). If auto-negotiation is enabled, this setting is ignored.

Duplex Mode Allows you set the port duplex mode (half- or full-duplex). If

auto-negotiation is enabled, this setting is ignored.

Flow Control Mode Determines if flow control is used on this port. For half-duplex

links, active backpressure jams the sending Ethernet channel until the port’s buffers can receive more packets. This prevents lost or dropped packets.

For full-duplex links, IEEE 802.3z pause control allows the port to stop a sending station from sending more packets if the receiving port’s buffers are full.

For TX and FX ports, there is an additional option for Enable with Aggressive Backoff. This option limits the size of the bursts.

Flow Control is recommended for use primarily on end-station connections. Using this flow control on trunk ports can cause unnecessary congestion on the network.

Auto Negotiation Mode

Allows you to set the port to auto-negotiate a speed and duplex mode. Auto-negotiate works best when the connection on the other end of the link is set to auto-negotiate as well. If you set a port to auto-negotiate, and the connection is not successful, set the port speed and duplex mode manually.

Auto Negotiation Speed/Duplex Advertisement

Determines what information the port advertises when it starts auto-negotiating. In most cases, 10/100 and Half/Full are the best settings, but there may be cases when you want to auto-negotiate one parameter, while keeping the other fixed.

Port PACE Priority

Prevents the switch from overwhelming the output buffer on lower-speed ports by placing a threshold on the percentage of port traffic that can be flooded packets (unknown unicasts and multicasts). You can optionally include known multicast packets in this percentage to further decrease the possibility of the port’s output buffer being overwhelmed.

Determines the percentage of a port’s forwarded traffic that can be unknown unicast and multicast (flooded). Lower this value if the port has overflow problems.

Determines the limit of packets allowed in a single burst. Accepted values are 1 to 2048. For Fast Ethernet ports, set this value lower than 1024 (output buffer capacity). Lower this value if the port has overflow problems.

Determines if the port detects 3Com’s proprietary PACE format as packets pass through the port. PACE allows a packet’s priority (higher priority packets move through the switch before lower priority packets) to be set at the adapter.

Using the All Ports Configuration Dialog Box

The All Ports Configuration dialog box allows you to apply the same parameter settings to all switch ports for P220 switches and in a module for the P550 using a single command.

To set all ports in a module:

1. In the System Configuration section of the Web Agent window, select Mod ules & Ports. The Module Information dialog box opens.

2. In the Ports column, click the number for the module you want to configure (for

example, 10 for 100Base-FX). The Port Configuration dialog box opens.

Note:

Configuring the Cajun P550 Switch (Layer 2 & Layer 3)

Configuring VTP Snooping

VTP is a Layer 2 protocol developed by Cisco to maintain VLAN configuration consistency among its switches. this protocol only runs over trunk ports that have enabled either Cisco ISL or IEEE 802.1Q tagging. VTP Snooping allows a Cajun switch to synchronize its VLAN configuration with that of a Cisco switch running VTP in the same network. VLAN additions, deletions, and name changes made on the network’s Cisco VTP server will be automatically updated on Cajun switches that have VTP Snooping enabled and have connectivity to the Cisco VTP server. VLAN changes made on a Cajun switch are not automatically updated on any other switch.

Note:

VTP Snooping is enabled by default. You would only need to change VTP Snooping port settings if you wanted to disable its ability to learn VLAN changes on the network’s Cisco VTP server.

4. Click APPLY to save your changes, or CANCEL to restore previous settings.

Connecting a Modem

In order to use the serial console port as a PPP console, you must connect a modem to the switch. When you use the specified serial cable and connectors, the switch will convert the normal DCE interface to a DTE interface that is used by modems.

When the switch is configured for PPP mode, it will periodically send the modem config string from the serial console port. This will synchronize the baud rates between the modem and the console port and configure the modem to operate with the switch’s DTE interface.

The switch does not use any output signals except for TXD. It uses the DTR (converted to DSR by the specified cable and connectors) input connected to the modem DCD output, to detect that the modem is connected. It supports XON/XOFF flow control (or none).

To connect a modem:

1. Attach a DB25M-RJ45 (P/N 38210003)connector to the modem.

2. Attach the DB9M-RJ45 MDCE connector to the switch’s serial console port on the

front panel of the switch.

Setting Summer Time Hours

Summer Time Hours, also referred to as Daylight Savings Time (DST), is the strategy of moving clocks ahead to provide greater amounts of daylight in the afternoon and to standardize time with other parts of the world. In many parts of the world, the Summer Time Hours algorithm is based on a standardized rule. For example, in the Western hemisphere, the rule used by most locations in Canada, Mexico, and the United States is to set clocks forward by one hour at 2:00 a.m. on the first Sunday in April and back an hour at 2:00 a.m. on the first Sunday in October annually. Many countries in Europe and Asia follow similar rules. The offset, or amount of time by which the clock is set forward or backward, varies from country to country.

Many parts of the world follow a one-time change of Summer Time Hours. When you configure the switch for these locations, you reset the clock by specifying a scheduled time and date.

Note: If you upgrade the Cajun P550 or P220 switch from a previous version, your

local time settings are saved as Greenwich Mean Time values. Ensure that you change the Summer Time Hours Algorithm before you set the clock.

Setting Recurring Summer Time Hours

3. Click Yes to reset the switch, or No to cancel the operation.

Managing Configuration Files

You can manage the system files that contain the configuration data for your Cajun P550 switch. When you first install the switch, or upgrade from a previous installation, your configuration parameters are stored in a startup.txt file located in the switch’s Non-Volatile Random Access Memory (NVRAM). When the switch is restarted, the startup.txt file runs and stores configuration parameters in volatile RAM as a running configuration.

Changes you make to the switch configuration are automatically recorded in RAM, but not in NVRAM. When you want to retain your current configuration, you must manually save it to NVRAM through the Web Agent or the Command Line Interface (CLI). For information about how to save your running configuration file to your startup configuration, refer to “Copying Running Configuration to Startup Configuration", later in this section. To determine changes you have made to your running configuration, you can view and compare your running and startup configuration files.

Configuring IPX Routing (Layer 3)

Overview

This chapter and its procedures are specific to Layer 3 configuration.

Included in this chapter:

❒ IPX Overview ❒ Configuring the Cajun Switch as an IPX Router

IPX Overview

The Internetwork Packet Exchange (IPX) protocol is a connectionless protocol that performs datagram delivery and routing in Novell NetWare networks. Each IPX address consists of three parts:

❒ Network Number — A 32-bit (8 characters) number that is normally assigned by

the network administrator.

❒ Node Number — A 48-bit (12 characters) number that is normally the MAC layer

address of the physical interface.

❒ Socket Number — A number used to route packets to different processes within

the same node.

The syntax of the IPX address is:

network node socket

For example:

00000 0A Ah 00 e0 3b124213 h 4003h

where 000000AAh is the network number, 00e03b124213h is the node number, and 4003h is the socket number associated with a running process on the end node (for example, RIP, NetWare Link State Protocol (NLSP)).

Cajun P550/P220 Switch Operation Guide 4-1

Configuring IPX Routing (Layer 3)

IPX Datagram Structure

The IPX datagram contains an IPX header and any data to be transferred on the network. The IPX header is a 30 byte header that contains 10 fields. Figure 4-1. illustrates a conceptual view of an IPX datagram:
