Chapter 1: Switch Management

Configuration Options

For advanced management capability, the Management Module provides a menu-driven system configuration program. This program can be accessed by a direct connection to the serial port on the rear panel (out-of-band), or by a Telnet connection over the network (in-band).

The management agent is based on SNMP (Simple Network Management Protocol). This SNMP agent permits the OmniStack® 6124 (OS-6124) to be managed from any PC in the network using in-band management software.

The management agent also includes an embedded HTTP Web agent. This Web agent can be accessed using a standard Web browser from any computer attached to the network.

The system configuration program and the SNMP agent support management functions such as:

•Enable/disable any port

•Set the communication mode for any port

•Configure SNMP parameters

•Configure VLANs or multicast filtering

•Display system information or statistics

•Configure the switch to join a Spanning Tree

•Download system firmware

•Restart the system

Backup Management Agent

Note the following points about master and backup management agents:

•The OS-6124 with software version 3.0 supports a master management agent and a backup management agent. The agent with the lower stack ID will be the master. If the system up time of the master is greater than 10 minutes, it downloads data to the backup agent. Any configuration changes made to the master agent will be synchronized with the backup agent within 1-2 minutes of the user selecting the “apply” command.

•Up to a maximum of two Management Modules (one master and one back-up), may exist within a stackable configuration, which may consist of up to six switches in a stack.

•The Management Modules (master or backup) cannot be “hot” inserted. The “hot” removal of the master or the backup Management Module will cause system instability and will require a manual reboot of the entire stack.

•The master management does not synchronize the application software with that of the backup management. Therefore, before insertion of the backup Management Module, one must make sure that it contains the same application software as the master Management Module (version 3.0 or greater). The master

1-1

Switch Management

management only synchronizes the configuration file, including any configuration updates, with the backup management.

•Upon the failure or “hot” removal of the master Management Module within a stackable configuration, the following occurs:

-A “Trap” is sent, a “Log event” is logged, the switch is re-booted and the backup Management Module takes over without loss of configuration settings.

-The fail-over time of master management to that of the backup management in a medium-size stackable configuration is approximately 2 minutes. Consequently network traffic is disrupted during the fail-over period.

-The backup management’s “Backup Master” state changes to a “Master” state and the switch Unit IDs will also reflect the new change.

-All ports will still be active and the switch will continue forwarding traffic in a normal operative manner.

-If a Management Module were to be re-installed, the newly-installed Management Module would assume the role of “Master” agent with the incumbent one changing status to that of “Backup Master” agent.

Closed-Loop Stack

Up to six OS-6124 switches can be stacked together by installing optional Stacking Modules. The OS-6100-RST-KIT Redundant Stacking Module kit allows you to configure a closed-loop architecture that provides fault-tolerant operation of the stack. If a switch or Stacking Module fails, the operation and management of the stack remains unaffected. This also allows a switch to be powered down and removed from a stack without disrupting the rest of the stack.

Note: The Redundant Stacking Module must be installed with the master Management Module in Unit 1 only. If backup management is used in conjunction with the closed-loop feature, the backup Management Module must be installed in Unit 2.

Required Connections

Console Port (Out-of-Band) Connections

Attach a VT100 compatible terminal or a PC running a terminal emulation program to the serial port on the switch’s rear panel. Use the null-modem cable provided with this package, or use a null modem connection that complies with the wiring assignments shown in Appendix B of this guide.

When attaching to a PC, set terminal emulation type to VT100, specify the port used by your PC (i.e., COM 1~4), and then set communications to 8 data bits, 1 stop bit, no parity, and 9600 bps (for initial configuration). Also be sure to set flow control to “none.” (Refer to “Configuring the Serial Port” on page 2-14 for a complete description of configuration options.)

Note: If the default settings for the management agent’s serial port have been modified and you are having difficulty making a console connection, you can display or modify the current settings using a Web browser as described under “Console Configuration” on page 3-5.

1-2

In-Band Connections

Prior to accessing the Management Module via a network connection, you must first configure it with a valid IP address, subnet mask, and default gateway using an out-of-band connection or the BOOTP protocol.

Note: By default BOOTP is disabled and the IP address is set to 192.168.10.1. To enable BOOTP, see “IP Configuration” on page 2-11.

After configuring the switch’s IP parameters, you can access the on-board configuration program from anywhere within the attached network. The on-board configuration program can be accessed using Telnet from any computer attached to the network. The switch and stack can also be managed by any computer using a Web browser (Internet Explorer 4.0, or Netscape Navigator 4.0 or above), or from a network computer using network management software.

Notes: 1. Use the Network Configuration menu to specify the maximum number of simultaneous Telnet sessions that are supported by the system (up to four).

2.The on-board program only provides access to basic configuration functions. To access the full range of SNMP management functions, you must use SNMP-based network management software.

Username :

Password :

If this is your first time to log into the configuration program, then the default user names are “admin” and “user,” both with a default password of “switch.” The administrator has Read/Write access to all configuration parameters and statistics. The user has Read Only access to the management program.

You should define a new administrator password, record it and put it in a safe place. Select Console Login Configuration from the Management Setup Menu and enter a new password for the administrator. Note that passwords can consist of up to 11 alphanumeric characters and are not case sensitive.

Notes: 1. Based on the default configuration, a user is allowed three attempts to enter the correct password; on the third failed attempt the current connection is terminated.

2.A banner message may be configured to appear before the Login screen. The banner message is a login security alert. (See “Configuring the Banner Message” on page 2-22.)

IP Address		192.168.10.1	IP address of the stack you are managing. The system supports
			SNMP over UDP/IP transport protocol. In this environment, all
			systems on the Internet, such as network interconnection devices
			and any PC accessing the agent module (or running management
			software) must have an IP address.
			Valid IP addresses consist of four decimal numbers, of 0 to 255,
			separated by periods. Anything outside of this format will not be
			accepted by the configuration program.
Netmask		255.255.255.0	Subnet mask of the switch you have selected. This mask identifies
			the host address bits used for routing to specific subnets.
Default Gateway			Gateway used to pass trap messages from the system’s agent to the
			management station. Note that the gateway must be defined if the
			management station is located in a different IP segment. No gateway
			IP address is configured as the default.
IP State		USER-CONFIG	Specifies whether IP functionality is enabled via manual
			configuration, or set by Boot Protocol (BOOTP). Options include:

USER-CONFIG - IP functionality is enabled based on the default or user specified IP Configuration. (This is the default setting.)

BOOTP Get IP - IP is enabled but will not function until a BOOTP reply has been received. BOOTP requests will be periodically broadcast by the switch in an effort to learn its IP address. (BOOTP values can include the IP address, default gateway, subnet mask, and TFTP server IP.)

Management Setup Menu

Assigning SNMP Parameters

Use the SNMP Configuration screen to display and modify parameters for the Simple Network Management Protocol (SNMP). The switch includes an on-board SNMP agent which monitors the status of its hardware, as well as the traffic passing through its ports. A computer attached to the network, called a Network Management Station (NMS), can be used to access this information. Access rights to the on-board agent are controlled by community strings. To communicate with the switch, the NMS must first submit a valid community string for authentication. The options for configuring community strings and related trap functions are described in the following sections.

		Alcatel OmniStack 6124
		< SNMP Configuration >
		Send Authentication Fail Traps : ENABLED
		SNMP Security
		IP Trap Managers
	<Apply>		<Ok>	<Cancel>
	Use <TAB> or arrow keys to move, <Space> to scroll options.
Parameter		Description
Send Authentication Fail Traps		Issue a trap message to specified IP trap managers whenever authentication
		of an SNMP request fails. (The default is disabled.)
SNMP Communities		Assigns SNMP access based on specified strings.
IP Trap Managers		Specifies management stations that will receive authentication failure
		messages or other trap messages from the switch.

Using the System Configuration Program

Console Login Configuration

Use the Management Setup: Console Login Configuration to restrict management access based on specified user names and passwords, or to set the invalid password threshold and time-out. There are only two user types defined, ADMIN (Administrator) and GUEST, but you can set up to five different user names and passwords. Only Administrators have write access for parameters governing the switch. You should therefore assign a user name and password to the default Administrator as soon as possible, and store it in a safe place. (If for some reason your password is lost, or you cannot gain access to the System Configuration Program, contact Alcatel Technical Support for assistance.) The parameters shown on this screen are indicated in the following figure and table.

		Alcatel OmniStack 6124
		< Console Login Configuration >
		Password Threshold		: 3
		Lock-out Time (in minutes) : 0
