13 CHAPTER Operations 3 Overview The CCM console management appliance and its ports are easily configured and managed to meet your requirements for device connection, user authentication, access control, power status monitoring, port history information display and Simple Network Management Protocol (SNMP) compliance for use with third party network management products.
14 CCM Installer/User Guide To update the boot or application firmware on the appliance, use the Server FLASH command (page 67). The appliance may be rebooted or reinitialized by pressing a button on the appliance or by issuing a command; see Rebooting and Reinitializing the CCM Appliance on page 10. Enabling/disabling features Table 3.
Chapter 3: Operations 15 Configuring Serial Port Settings You may configure a CCM port to support one of two types of target devices (TDs): SPC or console. For more information about SPC power control devices, see the SPC Installer/User Guide. A console TD may be a serial-managed Linux (or other Unix) server, router, firewall or other supported serial device. By default, CCM ports are configured with the settings listed in Table 3.2. Table 3.
16 CCM Installer/User Guide group). One or more port groups may then be specified in a user account. A group name may contain up to eight characters. Up to 8 port groups may be specified for a CCM850 appliance user, up to 16 port groups for a CCM1650 appliance user and up to 48 port groups for a CCM4850 appliance user. For example, assume that ports 1, 2, 3 and 4 are assigned to a group named LINUX. Ports 5, 6, 7 and 8 are assigned to a group named ROUTERS.
Chapter 3: Operations 17 transmit, receive and error counts. When you request information about a single port and a user is currently accessing that port, the display also includes the username, access rights and other information about the current session. When you request information about a single port configured as TD=SPC, the display includes information configured with the SPC command. A Show Port All command will indicate which ports are SPC ports.
18 CCM Installer/User Guide Standalone third party Telnet clients You may use third party Telnet clients to access the CCM appliance directly without AVWorks software. To connect to a device using Telnet: Type telnet, followed by the CCM appliance IP address and the appropriate TCP port, which by default is 3000 plus the physical port number, in decimal format. (The TCP port number may be changed for any CCM port.
Chapter 3: Operations 19 The optional Exclusive parameter requests exclusive access to the port. This is valid only if the port is not currently in use. See Session sharing on page 23 for more information. If you do not specify a port, a menu will be displayed, listing the ports that are available for serial connection. Enter a port number or name, or press Enter to cancel the command. If a valid port is specified, a message Connected to port ... appears.
20 CCM Installer/User Guide PPP dial-in may be used to access a remote CCM appliance that does not warrant a WAN (Wide Area Network) link to the Ethernet interface. The PPP dial-in may also be used to access a subnet containing remote devices in the event of a WAN link failure. In this case, the PPP provides an alternate path to one or more remote devices. To use PPP, you must configure a modem in autoanswer mode on the console port; see Configuring and using dial-in connections on page 19.
Chapter 3: Operations 21 SSH server keys When SSH is enabled for the first time, all sessions are terminated and the CCM appliance generates an SSH server key. The key generation process may take up to three minutes. The key is computed at random and is stored in the CCM configuration database. In most cases, the SSH server key should not be modified because most SSH clients will associate the key with the IP address of the CCM appliance.
22 CCM Installer/User Guide Table 3.3: SSH Authentication Methods (Continued) Method Description PW&KEY or KEY&PW SSH connections will be authenticated using both a username/password and an SSH key. With this method, a user’s definition must include a password and SSH key information for that user to authenticate an SSH session. PW authentication will be local or RADIUS as specified in the Auth parameter of the Server Security command. Key authentication is always local.
Chapter 3: Operations 23 To enable SSH session access to the CCM appliance: 1. Issue a Show Server Security command to ensure that you are using an authentication method other than None. SHOW SERVER SECURITY 2. Issue a Server SSH command with the Enable parameter. You may also specify an authentication method. SERVER SSH ENABLE AUTH= If an authentication method is not specified, the previous authentication parameter will be used. The default value is AUTH=PW. 3.
24 CCM Installer/User Guide • The CCM1650 appliance allows up to 32 total concurrent sessions, with up to four concurrent sessions per port. • The CCM4850 appliance allows up to 96 total concurrent sessions, with up to four concurrent sessions per port. You may: • Disable sharing. In this case, only one session per port may be active at a time. • Enable automatic session sharing.
Chapter 3: Operations 25 Example 2 - RU’s access level is equal to or higher than SO’s access level Share mode = Disabled -orSO is connected exclusively RU is prompted with preemption choices E, N and D. If RU replies with E, then SO will be preempted/disconnected and RU will be connected exclusively to the port. If RU replies with N, then SO will be preempted/disconnected and RU will be connected non-exclusively to the port.
26 CCM Installer/User Guide To initiate a device session with exclusive access: At the Username: prompt, enter your username, followed by an E or e. -orIf device connections from the console port are enabled, enter a Connect command, followed by a port number or name, then the Exclusive parameter. NOTE: A request for an exclusive connection is valid only when there are no other users currently using the port. To display share mode information: Issue a Show Server command.
Chapter 3: Operations 27 Ending Device Sessions To end your session: Enter CLI mode and issue a Quit command. - or If you initiated the device session with a Connect command, enter CLI mode and issue a Disconnect command. - or Allow the port to time-out due to inactivity. In this case, a notification message is issued and the serial CLI session returns to CLI mode. This time-out may occur while you are in CLI mode.
28 CCM Installer/User Guide To add a user: Issue a User Add command. USER ADD [PASSWORD=] [SSHKEY=] [FTPIP=] [KEY=] [ACCESS=] [GROUP=[,...]] 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/access rights and group names.
Chapter 3: Operations 29 Table 3.4: Access Rights Access Right Description PCON The Port Configuration access right allows the user to modify port settings. Grant PCON access only to users who need to issue the Port Set command. SCON The Server Configuration access right allows the user to change the CCM configurations, including setting the IP address and updating the program load in FLASH. Grant SCON access only to users who need to administer the CCM appliance.
30 CCM Installer/User Guide 3. To display the access rights and level for one or all users, issue a Show User command. SHOW USER |ALL For more information, see Managing User Accounts on page 27 plus User Add command on page 87, User Set command on page 89 and Show User command on page 83. Using Authentication Methods The CCM appliance supports several methods for authenticating users: local, RADIUS and none. Multiple connection and authentication methods may operate concurrently.
Chapter 3: Operations 31 No authentication When authentication is disabled, users are not authenticated. Telnet sessions to serial ports are accepted immediately, and users are not prompted for a username or password. In this case, users are granted access only to the port to which they are connected, including Break access. Connections to the Telnet port (23), serial CLI and PPP are still authenticated using the local CCM user database, even when authentication is expressly disabled.
32 CCM Installer/User Guide 2. Issue a Server Security command, using the Authentication parameter to specify the authentication method. Use the Encrypt parameter to enable plain text Telnet connections, SSH connections or both. SERVER SECURITY AUTHENTICATION= ENCRYPT= You may optionally specify both RADIUS and local authentication, in either order. In tis case, authentication will be attempted initially on the first method specified.
Chapter 3: Operations 33 Managing Port History Each CCM appliance serial port has a circular history buffer that contains the latest 64K bytes of data received from the attached serial device. You may enable the NFS feature, which will write buffered data to a file on an NFS server. Port history information may be useful for auditing and troubleshooting.
34 CCM Installer/User Guide Table 3.6: Port History Mode Commands (Continued) Command Description Search S searches the port history buffer for a specified text string. Search strings with embedded spaces must be enclosed in quotes. By default, the search is case sensitive. To ignore case, enter -i before the string. To specify direction, type -u to search up from the current line toward the top of the buffer or -d to search down from the current line toward the bottom of the buffer.
Chapter 3: Operations 35 • If Clear is specified, the port history buffer is cleared and all data is discarded at the end of a session. • If Keep is specified, the port history buffer’s content is retained at the end of a session. To clear and discard all data in a port history buffer: Issue a Clear command while you are in port history mode. CLEAR - or Issue a Server CLI command, indicating History=Clear.
36 CCM Installer/User Guide The valid file types are: • Linear - A file will be opened for writing at the end (appended); this is the default • Daily - A new file will be created every midnight By default, the TCP network protocol is used for communications between the CCM appliance and the NFS server. You may use the Protocol parameter to specify the UDP or TCP protocol. To enable/disable NFS on the CCM appliance: 1. To enable NFS on the appliance, issue an NFS command with the Enable parameter.
Chapter 3: Operations 37 be also be unique for each day. You may use the substitution strings listed in Table 3.7 as part of the filename specification, regardless of the file type. Table 3.
38 CCM Installer/User Guide If you specify a nondefault filename, and later attempt to change the file type from linear to daily, the request will be rejected if the filename specification does not include a date substitution string. When writes will occur When you enable NFS on a port, you may configure a buffer size and a time interval, which will be used to determine when accumulated data is written to the NFS server file.
Chapter 3: Operations 39 Managing the CCM Appliance Using SNMP The CCM console management appliance provides a set of commands that create and manage SNMP structures for use by third party network management products.
40 CCM 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 If no management entities are defined, any SNMP manager may access the MIB.
Chapter 3: Operations 2. 41 To delete an SNMP trap destination address, issue a Server SNMP Trap Destination command with the Delete parameter and the destination’s IP address. SERVER SNMP TRAP DESTINATION DELETE For more information, see Server SNMP Trap Destination command on page 75. To add, copy or delete port alert strings: 1. To add a port alert string, issue a Port Alert Add command, specifying the port and a 3-32 character string.
