This chapter describes first-time startup procedures for the Cisco AccessPath Integrated Access System, including IP address and interface configuration. It assumes you have installed the AccessPath system as described in the Cisco AccessPath Integrated Access System Hardware Installation and Configuration Guide and Regulatory Compliance and Safety Information for the Cisco AccessPath Integrated Access System.
This chapter includes the following sections:
The AccessPath system is available in the following configurations:
The configuration procedures in this chapter include steps to clear NVRAM and reload the configuration file for each shelf. You should not clear NVRAM, however, unless you intend to configure the shelf from scratch, or download your factory-preconfigured configuration file from a local TFTP server.
Note The sample configurations in this chapter reflect the factory standard configurations for T1 PRI configurations running the Multilink Point-to-Point Protocol (MP, also known as MLP) in an AccessPath system with two Router Shelves. If you are using a different standard configuration, or a custom configuration, your configuration files will be different from the samples.
If your AccessPath system includes the optional AccessPath Manager (APM), you should use it to perform the first time startup tasks described in this chapter. Refer to the document Installing Cisco AccessPath Manager and the online help that comes as part of the AccessPath Manager software.
When adding shelves to the AccessPath system, make sure the new shelf is running a compatible Cisco IOS software image; if it is not, install that software image before proceeding. For information on the correct Cisco IOS software images for each shelf, refer to the document Release Notes for the Cisco AccessPath Integrated Access System. For instructions on installing Cisco IOS software, refer to the appropriate software configuration guide on the CD or on CCO.
Note Release Notes for each release of the Cisco IOS software are included on the CD shipped with the AccessPath system, and on the web via Cisco Connection Online (CCO).
The preferred way to configure shelves in the AccessPath system is by using the AccessPath Manager (APM). If your AccessPath system includes the optional AccessPath Manager, you should use it to perform the first time startup tasks described in this chapter. Refer to the document Installing Cisco AccessPath Manager and the online help that comes as part of the AccessPath Manager software.
If your AccessPath system does not include the AccessPath Manager, or if you prefer to configure the AccessPath system via the command line interface, follow the instructions in this section.
Note Access to stack members (AccessPath system shelves) via the Failsafe/Console Management Shelf is intended for initial configuration and emergency recovery. During normal operation, this method of access can adversely impact the performance of the AccessPath system.
All shelves in the AccessPath system are configured through the Failsafe/Console Management Shelf. Because the console port of each shelf in the AccessPath system is connected to a serial port on the Failsafe/Console Management Shelf, an administrator can gain access to each shelf by telneting to a specific port on the Failsafe/Console Management Shelf.
In the port numbering scheme used, port 2001 on the Failsafe/Console Management Shelf connects to the first Access Server Shelf (nas01), port 2002 to nas02, and so on, with port 2016 connected to the Switch Shelf, port 2015 to the first Router Shelf, and port 2014 to the optional second Router Shelf, if present.
The Failsafe/Console Management Shelf facilitates access to the command line interface of all shelves in the Cisco AccessPath Integrated Access System. Refer to the Chapter 2, "Working with the EXEC Facility," if you are not familiar with the command line interface.
You can connect to the Failsafe/Console Management Shelf in the following ways:
For information about how to attach a terminal or modem to the Failsafe/Console Management Shelf, refer to Chapter 6, "Configuring a Modem for the Cisco AccessPath Integrated Access System," and the Cisco AccessPath Integrated Access System Hardware Installation and Configuration Guide.
This section describes how to connect to the Failsafe/Console Management Shelf, set an enable password, and view the configuration file. The section includes a sample configuration for the Failsafe/Console Management Shelf.
The following example shows a Telnet connection to the Failsafe/Console Management Shelf (named FC/M_Shelf):
Step 2 Enter enable mode.
In the following example, the user enters enable mode (without entering a password, because none has yet been set).
Step 3 (Optional). Erase the startup configuration located in NVRAM. If you choose not to erase the startup configuration, continue with Step 5.
Step 4 (Optional). Reload the operating system.
If you cleared NVRAM, the reload command will reload the default configuration file, not the configuration you ordered from the factory.
Note If, when you are issuing a reload command, you receive a prompt asking if you would like to save your configuration, answer n. If you answer y, you will be saving the current configuration back into NVRAM and need to issue the erase startup-config command again in order to reload the default configuration file.
The following example shows output from the reload command (user response in boldface).
(Output truncated for readability).
Step 5 Enter enable mode and set a password for enable mode.
In the following example, the user enters enable mode (without entering a password, because none has yet been set) and specifies cisco as the password for enable mode. Users attempting to enter enable mode in future will be prompted for a password. (Refer to the section "Securing Access to Privileged EXEC and Configuration Mode" in Chapter 7.)
Step 6 View the default configuration.
You can now configure the Failsafe/Console Management Shelf. See the following section, "Sample Failsafe/Console Management Shelf Configuration," for additional configuration guidelines.
This section describes how to connect to the Switch Shelf, enter enable mode, and set an enable password. The section includes a sample configuration for the Switch Shelf.
In the following example the Failsafe/Console Management Shelf, at IP address 192.168.1.234, connects to the Switch Shelf on port 2016:
Step 2 Enter enable mode.
In the following example, the user enters enable mode (without entering a password, because none has yet been set).
Step 3 (Optional.) Clear NVRAM. If you choose not to clear NVRAM, continue with Step 4.
In the following example, the user clears NVRAM. Note that when you issue the clear config all command, the Switch Shelf automatically resets itself with the default configuration.
(Output truncated for readability.)
Step 4 Set an enable password.
In the following example, the user specifies secret as a password for enable mode. Users attempting to enter enable mode in future will be prompted for a password. (Refer to the enable command in the Catalyst 5000 Series Configuration Guide and Command Reference.)
Note If you cleared NVRAM in Step 3, the Switch Shelf will automatically reload the default configuration file and return the enable prompt.
Step 5 View the configuration.
You can now configure the Switch Shelf. See the following section, "Sample Switch Shelf Configuration," for additional configuration guidelines.
This section describes how to connect to an Access Server Shelf, substitute your own IP addressess for the placeholder addresses in the configuration file, and configure interfaces.
This section also includes a sample configuration for the Access Server Shelf.
In the following example the Failsafe/Console Management Shelf, at IP address 192.168.1.234, connects to the Access Server Shelf nas01 on port 2001:
Step 2 Enter enable mode.
In the following example, the user enters enable mode (without entering a password, because none has yet been set).
Step 3 (Optional.) Clear NVRAM. If you choose not to clear NVRAM, continue with Step 6.
Step 4 (Optional.) Reload the operating system.
Note If, when you are issuing a reload command, you receive a prompt asking if you would like to save your configuration, answer n. If you answer y, you will be saving the current configuration back into NVRAM and need to issue the erase startup-config command again in order to reload the default configuration file.
(Output truncated for readability).
Step 5 Set a password for enable mode.
In the following example, the user specifies secret as the password for enable mode. All future attempts to enter enable mode will be met with a password prompt. (Refer to the section, "Securing Access to Privileged EXEC and Configuration Mode," in Chapter 7.)
Step 6 Write the Access Server Shelf configuration to the terminal to view it (and for reference when configuring IP addresses).
Step 7 Enter global configuration mode and add the IP address and subnet mask for interface Ethernet 0, and exit.
Step 8 Enter interface configuration mode, add the IP address and subnet mask for interface serial 0 (for network management), and exit.
Step 9 Create a stack group, add the correct IP address for the Router Shelf (or shelves), exit global configuration mode, and save the configuration.
Note Stack group and stack group member names are case-sensitive.
Step 10 Repeat Step 1 through Step 9 for each Access Server Shelf.
You can now configure the Access Server Shelves. See the following section, "Sample Access Server Shelf Configuration," for additional configuration guidelines.
Note The above procedure does not cover all of the steps required for an Access Server Shelf configuration. For more information, refer to the Cisco AS5200 Universal Access Server Software Configuration Guide.
This section begins by describing how to connect to a Router Shelf, clear NVRAM, and reload the configuration file. If your Cisco AccessPath Integrated Access System was fully configured at the factory, it requires no further configuration and you can ignore this entire section.
If your AccessPath system was partially configured at the factory and you need to configure interfaces and substitute your own IP addressess for the placeholder addresses in the configuration, follow this procedure.
A sample configuration file is included at the end of this section.
In the following example, the Failsafe/Console Management Shelf, at IP address 192.168.1.234, connects to the Router Shelf on port 2015:
Step 2 Enter enable mode.
In the following example, the user enters enable mode (without entering a password, because none has yet been set).
Step 3 (Optional) Clear NVRAM. If you choose not to clear NVRAM, go to Step 5.
Step 4 (Optional). Reload the operating system.
If you cleared NVRAM, the reload command will reload the default configuration file, not the configuration you ordered from the factory.
Note If, when you are issuing a reload command, you receive a prompt asking if you would like to save your configuration, answer n. If you answer y, you will be saving the current configuration back into NVRAM and need to issue the erase startup-config command again in order to reload the default configuration file.
The following example shows output from the reload command (user response in boldface).
(Output truncated for readability).
Step 5 Set a password for enable mode. In the following example, the user specifies cisco as the password for enable mode. All future attempts to enter enable mode will be met with a password prompt. (Refer to the section, "Securing Access to Privileged EXEC and Configuration Mode," in Chapter 7.)
Step 6 Write the Router Shelf configuration to the terminal to view it (and for reference when configuring IP addresses).
Step 7 Enter global configuration mode, create a stack group, and add all Access Server Shelves to this stack group (it is not necessary to add the other Router Shelf).
Step 8 Add an IP address and subnet mask to the loopback interface, and exit the loopback interface.
Step 9 Add an IP address and subnet mask to the Fast Ethernet interface, and exit the interface.
Step 10 Add an IP address and subnet mask to the backhaul interface, exit the interface, and exit global configuration mode. (In this example, we will configure a serial interface, but your AccessPath system may be configured for another kind of backhaul interface, such as HSSI, ATM, FDDI, or Fast Ethernet.)
Step 11 Write the configuration to memory.
Step 12 Ping each Access Server Shelf in turn to verify that the configurations are correct and that all devices are communicating. Your output will look similar to this:
You can now configure the Router Shelves. See the following section, "Sample Router Shelf Configuration," for additional configuration guidelines.
Note The above procedure does not cover all of the steps required for a Router Shelf configuration. For more information, refer to the Cisco 7206 Installation and Configuration Guide.
