10 CPS Installer/User Guide Installing the CPS See Appendix B for device cabling information. WARNING: The power outlet should be installed near the equipment and should be easily accessible. To install the CPS hardware: 1. Locate the CPS where you can connect cables between the serial devices and the CPS serial ports, and where you can connect a LAN interface cable between the Ethernet hub or switch and the CPS LAN connector.
Chapter 2: Installation and Configuration 11 Configuring the IP address and subnet mask You may use any of three methods to configure the CPS IP address and subnet mask: BootP, Telnet Command Line Interface (CLI) or the serial CLI on port 1. These methods work as documented on most Windows® and UNIX systems; however, the actual implementation on your system may differ from the instructions provided. Refer to your system administrator guide. To configure the IP address and subnet mask using BootP: 1.
12 CPS Installer/User Guide After the IP address is configured successfully, launch a Telnet session to the CPS IP address. Then, see Initial CPS login in this chapter. To configure the IP address and subnet mask using a Telnet CLI: 1. Ensure that your server or workstation has a Telnet client and is located on the same LAN segment as the CPS. 2. Use the arp command to update the server or workstation with the CPS IP address and Ethernet MAC address.
Chapter 2: Installation and Configuration 4. 13 Proceed to Initial CPS login in this chapter. After you complete the CPS configuration, you may reconfigure the CLI on another port or disable it completely and use port 1 with an attached device. For more information, see Connecting to devices from the serial CLI port in Chapter 3. Initial CPS login The CPS ships with a single user defined in its user database.
14 CPS Installer/User Guide Reinitializing the CPS Reinitializing the CPS removes configured information. This may be useful when reinstalling the CPS at another location in your network. The CPS stores configuration information in FLASH databases. During reinitialization, the FLASH erase has two phases. The first phase erases the CPS configuration database, which contains all nonvolatile data except the IP address.

Chapter 3: Operations 17 Chapter 3: Operations Overview The CPS and its ports can be easily configured and managed to meet your requirements for device connection, user authentication, access control, power status monitoring, port history information display and SNMP compliance for use with third-party network management products. Support for SSH (Secure Shell) access via third-party clients is also provided.
18 CPS Installer/User Guide To configure serial console port settings: Issue a Port Set command. You may specify settings for one or all ports. PORT [|ALL] SET TD=CONSOLE [NAME=] [BAUD=] [SIZE=] [PARITY=] [STOP=] [FLOW=] [TIMEOUT=] [CHAR=^] [TOGGLE=NONE|DTR] [POWER=] To configure SPC ports and settings: Issue a Port Set command with the TD=SPC parameter.
Chapter 3: Operations 19 Connecting to Serial Devices The CPS offers several methods for connecting to attached serial devices: Telnet, serial CLI, PPP and SSH. If a user attempts to connect to a port that is already in use, and if the user attempting to connect has an access level equal to or higher than the currently-connected user, the connecting user will be prompted with the choice of preempting the current user or dropping the connection.
20 CPS Installer/User Guide Connecting to devices using Telnet Each CPS serial port is directly addressable via a unique TCP port number that provides a connection to the attached serial device. To connect to a device using Telnet: Type telnet, followed by the CPS IP address and the appropriate TCP port number, which by default is 3000 plus the physical port number, in decimal format. (The TCP port number can be changed for any CPS port.
Chapter 3: Operations 21 Standalone third-party Telnet clients You may use third-party Telnet clients to access the CPS directly without DS management software. Connecting to devices from the serial CLI port By factory default, port 1 of the CPS is configured with the serial CLI, which prohibits the use of port 1 with an attached serial device. You can configure the CLI on a different port, but only one port may be configured as the serial CLI port at one time.
22 CPS Installer/User Guide 3. To end a device session that was initiated with a Connect command, issue a Disconnect command. DISCONNECT For more information, see Server CLI command, Connect Command and Disconnect Command in Chapter 5. Connecting to devices using PPP The CPS supports remote PPP access using an auto-answer modem that answers calls and establishes the PPP protocol with a dial-in client.
Chapter 3: Operations 23 For more information, see Show Server CLI command and Server PPP command in Chapter 5. To display PPP configuration information: Issue a Show Server PPP command. SHOW SERVER PPP For more information, see Show Server PPP command in Chapter 5. Configuring and using dial-in connections You can attach an external modem to the CPS serial CLI port for dial-in serial CLI access to the CPS. This may be used as a backup connection if the CPS is not accessible from the network.
24 CPS Installer/User Guide Connecting to devices using SSH The CPS supports version 2 of the SSH (Secure Shell) protocol (SSH2). The CPS SSH server operates on the standard SSH port 22. The shell for this connection provides a CLI prompt as if you had established a Telnet connection on port 23. The shell request for this connection is for CLI access. Additional CPS SSH servers operate on TCP ports that are numbered with values 100 greater than the standard 30xx Telnet ports for the CPS.
Chapter 3: Operations 25 SSH Authentication Methods Method Description PW (default) SSH connections will be authenticated with a username/ password. With this method, a user’s definition must include a valid password in order for that user to authenticate an SSH session. A password can authenticate to a DSAuth or RADIUS server or to the local user database. KEY SSH connections will be authenticated with an SSH key.
26 CPS Installer/User Guide For more information, see Using Authentication Modes and Encryption in this chapter. SSH user keys A user’s SSH key is specified in a User Add or User Set command. You may define a key even if SSH is not currently enabled.
Chapter 3: Operations 4. 27 If you are reenabling SSH, you are prompted to use the existing SSH server key or generate a new key. Enter Y to use the existing key or N to generate a new key. For more information, see Server SSH command in Chapter 5. To disable SSH session access to the CPS: Issue a Server SSH command with the Disable parameter. SERVER SSH DISABLE When SSH is disabled, the CPS operates in plain text mode, unless SSL encryption is enabled.
28 CPS Installer/User Guide command may be used to override the Server CLI access character on a per-port basis. For more information, see Server CLI command and Port Set command in Chapter 5. To display CLI access character information: Issue a Show Server CLI command. SHOW SERVER CLI For more information, see Show Server CLI command in Chapter 5. Ending device sessions To end your CPS session: Enter CLI mode and issue a Quit command or a User Logout command.
Chapter 3: Operations 29 To add a user: Issue a User Add command. USER ADD [PASSWORD=] [SSHKEY=] [FTPIP=] [KEY=] [ACCESS=] You must specify a username. You must also specify a password or SSH user key information, or you may specify both. You may also include an access level or access rights. For more information, see Connecting to devices using SSH and Access rights and levels in this chapter and User Add command in Chapter 5.
30 CPS Installer/User Guide 2. To display information about all users, issue a Show User command with the All parameter. SHOW USER ALL For more information, see Show User command in Chapter 5. Access rights and levels Most CPS commands require the user to have access rights to use the commands. The access rights for each CPS command are listed in Chapter 4. The following table describes the access rights a user may be given.
Chapter 3: Operations • 31 The ADMIN level is equivalent to PALL, USER, SMON, PCON and BREAK A user’s access level can be used for preemption. For example, assume User A is connected to a port. User B tries to connect to the same port. If User B has an access level equal to or greater than User A’s access level, then User B will be given the option of preempting User A. When using DSView software, there are two access rights levels: user and administrator.
32 CPS Installer/User Guide Local authentication Local authentication uses the CPS unit’s internal user database to authenticate users. RADIUS authentication RADIUS authentication uses an external third-party RADIUS server containing a user database to authenticate CPS users. The CPS, functioning as a RADIUS client, sends usernames and passwords to the RADIUS server.
Chapter 3: Operations 33 This method cannot be used when SSH connections are enabled, nor can it be combined with any other authentication method. Authentication summary The CPS allows concurrent use of multiple authentication modes. This allows Telnet, SSH and DSView clients to all access a single CPS as long as the appropriate authentication methods are enabled. For example, if you enable DS and local authentication, DSView clients will always be authenticated using DSAuth.
34 CPS Installer/User Guide ENCRYPT= DSAUTH= If you specify DS authentication, you must: Specify the IP address of a primary DS authentication server and optionally, the IP address of a secondary DS authentication server. - or Indicate that any DS authentication server may be used. If you specify DS authentication, encryption is automatically enabled. 3. You are prompted to save the information. Enter Y to confirm or N to cancel. To display authentication configuration information: 1.
Chapter 3: Operations 35 Since the CPS allows multiple connection modes to operate concurrently, you can specify multiple encryption types. For example, the following command enables connections via Telnet and via DSView SSL Telnet using Triple DES or RC4 encryption. server security encrypt=none,3des,128 The following command enables connections via DSView SSL Telnet using only DES. SSH2 client connections are also enabled, but plain text Telnet sessions are not allowed.
36 CPS Installer/User Guide A locked-out user will remain locked-out until the specified time elapses, the CPS is power-cycled or the user is unlocked by an administrator with the User Unlock command. A user with the ADMIN access level can unlock all users except a user with the APPLIANCEADMIN level. A user with the APPLIANCEADMIN level can unlock all users. To enable or disable Security Lock-out: 1.
Chapter 3: Operations 37 Port History Mode Commands Command Description Bottom B sets the view location to the bottom of the file minus 23 history display lines, if available. Clear C clears the port history buffer. Next N increments the current history display line by the number of lines per page and outputs a new history display page. Prev P decrements the current history display line by the number of lines per page and outputs a new history display page. Quit Q returns to the normal CLI.
38 CPS Installer/User Guide To access port history mode: Issue a Port History command. PORT HISTORY The PORT HISTORY > prompt appears. To control the port history buffer display when you connect: Issue a Server CLI command, using the History parameter to specify the Hold or Auto option: SERVER CLI HISTORY=HOLD|AUTO • If Hold is specified, the number of bytes in the history buffer is displayed, but none of the history data is output.
Chapter 3: Operations 39 Managing SNMP Structures The CPS provides a set of commands that create and manage SNMP structures for use by third-party network management products.
40 CPS Installer/User Guide When you define at least one SNMP manager, SNMP requests are processed if they are from one of the defined SNMP managers. If a request is not from one of the defined SNMP managers, the SNMP request is discarded. 2. To delete an SNMP management entity address, issue a Server SNMP Manager command with the Delete parameter and the management entity’s IP address. SERVER SNMP MANAGER DELETE For more information, see Server SNMP Manager command in Chapter 5.
Chapter 3: Operations 41 To add or delete SNMP trap destination addresses: 1. To add an SNMP trap destination address, issue a Server SNMP Trap Destination command with the Add parameter and the destination’s IP address. You may define up to four destination addresses, using separate commands. SERVER SNMP TRAP DESTINATION ADD 2. To delete an SNMP trap destination address, issue a Server SNMP Trap Destination command with the Delete parameter and the destination’s IP address.
42 CPS Installer/User Guide To display SNMP configuration information: Issue a Show Server SNMP command. SHOW SERVER SNMP The display includes information specified with the Server SNMP, Server SNMP Community, Server SNMP Manager, Server SNMP Trap and Server SNMP Trap Destination commands.
