4 C ONFIGURING B ASIC S ETTINGS This chapter describes preliminary tasks for configuring basic bridge/r outer settings. Before you begin configuring ports and paths (described in Chapter 1 of Using Enterprise OS Software ), complete the following tasks: ■ Log on to the system.
18 C HAPTER 4: C ONFIGURING B ASIC S ETTINGS 3 Log on as root: root 4 Press the Return key . Pressing the Return key when prompted for the password enters a null string, which is the default local password. Later in this chapter , you will be instructed on how to change the password.
Learning About the User Interfaces 19 Accessing the User Interface T o access the user interface or to modify the configuration of the bridge/router or tunnel switch, use one of the following methods: ■ Access the bridge/router commands locally thr ough the console port.
20 C HAPTER 4: C ONFIGURING B ASIC S ETTINGS 5 Log in as root. T ype: root or admin 6 Click the OK button to enter a null string as the password, which is the default local password. The default Web Link page opens in the br owser window . Web Link Interface Description The Web Link application window has thr ee frames.
Learning About the User Interfaces 21 The Main menu (Level 1) is displayed. Depending on your software package, the number of services in your Main menu may vary . 2 Select the service you want to use. For example, selecting 1 from the Main menu (Level 1) display generates a menu for the SYS Service.
22 C HAPTER 4: C ONFIGURING B ASIC S ETTINGS The value part of the command specifies how you want the parameter to be set. V alues include numerics, strings, or addr esses, depending on the parameter . For additional information, see “Syntax for Assigning V alues” on page 28 .
Learning About the User Interfaces 23 Figure 2 Abbr eviated Syntax Additional syntax examples are pr ovided in “Full and Abbreviated Syntax Examples” on page 24 .
24 C HAPTER 4: C ONFIGURING B ASIC S ETTINGS Full and Abbreviated Syntax Examples The following examples show the full form first, followed by the abbreviated command syntax. The full-form command syntax: ADD !<port> -NRIP AdvToNeighbor <network>%<mac address> [.
Learning About the User Interfaces 25 V ariations in Command Syntax Each command has its own syntax. When a command is used for configuring parameters, its syntax or values may change according to the parameter and service.
26 C HAPTER 4: C ONFIGURING B ASIC S ETTINGS Software . For more information about the Curr entPorts parameter , see Reference for Enterprise OS Software . The syntax convention for ports, virtual ports, and group ports is: !<port> For a port, <port> is a variable ID number , for example, !1.
Learning About the User Interfaces 27 Privilege Level The privilege level determines which commands and parameters a user can access. The network manager must set the Network Manager password and the User password to be the same in or der to provide equal levels of security .
28 C HAPTER 4: C ONFIGURING B ASIC S ETTINGS Syntax for Assigning V alues Most parameters must be assigned a value of a particular type. T able 4 shows the possible types. The SET , SETDefault, and SYSgen commands requir e both parameter names and parameter values.
Learning About the User Interfaces 29 example, to include an apostrophe in string text, enter a backslash followed by an apostrophe ('). T o include a backslash () in string text, enter two backslashes (). The first backslash prevents the bridge/r outer from tr eating the second as a special character .
30 C HAPTER 4: C ONFIGURING B ASIC S ETTINGS The syntax variation for non-ISDN interfaces applies to local area network (LAN) and data terminal equipment (DTE) interfaces. Enterprise OS software menus and help strings do not display the syntax variation for ISDN interfaces.
Learning About the User Interfaces 31 Frame Relay Requires an addr ess called a Data Link Connection Identifier (DLCI). DLCIs are assigned by the appr opriate authority at subscription time. A DLCI follows an at sign (@) and can range from 1 thr ough 1022 decimal.
32 C HAPTER 4: C ONFIGURING B ASIC S ETTINGS Network Layer Addresses ISDN An ISDN address is a phone number provided by your telecommunications carrier . It can include a dial prefix, country code, area code, and phone number . It can consist of a maximum of 30 characters.
Learning About the User Interfaces 33 T able 6 Internet Address Format Class Range of First Address Field Address Format A 0–127 nnn.hhh.hhh.hhh * * n represents a digit of the network number; h represents a digit of the host number. B 128–191 nnn.
34 C HAPTER 4: C ONFIGURING B ASIC S ETTINGS Getting Help The user interface provides help menus as memory aids. T o display the help menu, enter a question mark (?).
Obtaining Network Manager Privilege Level 35 modifying it and see the new value, the new value has taken effect immediately . If a command changes only the default value, the new value takes effect only after reboot.
36 C HAPTER 4: C ONFIGURING B ASIC S ETTINGS T o change the password, follow these steps: 1 At the Enterprise OS prompt (Enterprise OS #), enter: SysPassWord When a menu is displayed, Select 1, Set Network Manager Privilege Password. 2 Enter the new Network Manager password.
Assigning Internet Addresses 37 The system location can contain no more than 255 characters. The default value is “ “ (null string). 3 Specify a string that identifies the contact person managing.
38 C HAPTER 4: C ONFIGURING B ASIC S ETTINGS The following example illustrates how to assign an Internet address to a bridge. Example Figure 3 shows a configuration in which you need to assign an Internet address to a bridge. Hosts A and B are two hosts belonging to the same IP network, network 10.
Assigning Internet Addresses 39 Figure 4 Assigning an IP Addr ess to a bridge/r outer Port For additional information on Internet addresses and subnet masks, see Using Enterprise OS Software . After assigning an Internet address or addresses to the bridge/router or tunnel switch, go to Chapter 1 in Using Enterprise OS Software.
40 C HAPTER 4: C ONFIGURING B ASIC S ETTINGS If you do not plan to be connected to the Internet, you can assign network addresses on your own. However , if you plan on accessing the Internet in the future, you may want to apply for an Internet network address so you will not have to change network addresses when you make the connection.
NETBuilder Security 41 For example: ADD -SNMP COMmunity “public” TRiv RO AL1 4 Create a new manager with r ead/write access to the bridge/router or tunnel switch. For security reasons, limit the number of network management stations. For example: ADD -SNMP MANager “private” 129.
