Prerequisites for Basic Configuration of a Cisco Networking Device
Prerequisites for Cisco IOS AutoInstall
-
Using AutoInstall to Remotely Configure Cisco Networking Devices module is written specifically for networking devices running Cisco IOS Release 12.4(1) or newer. However most of the information in this document can be used to configure networking devices that support AutoInstall and are not running Cisco IOS release 12.4(1) or newer. The two key differences that you must allow for are: - Some Cisco networking devices use BOOTP instead of DHCP to request IP address addresses over LAN interfaces. Enabling BOOTP support on your DHCP server will resolve this issue.
- Some Cisco networking devices use a DHCP client identifier format that is different from the format used by networking devices running Cisco IOS release 12.4(1) or newer. This document only explains the DHCP client identifier format used by networking devices running Cisco IOS release 12.4(1) or newer. Use the process described in the “Determining the Value for the DHCP Client Identifier Automatically” section in Using AutoInstall to Remotely Configure Cisco Networking Devices module to determine the DHCP client identifier format that your Cisco networking device is using.
-
No configuration file resides in NVRAM on the networking device that is being configured with AutoInstall.
-
The configuration files that you want to load on to the networking device using AutoInstall reside on a TFTP server that is connected to the network. In most cases there is more than one file; for example, a network file with the IP-to-hostname mappings and a device-specific configuration file.
-
You have someone at the remote site to connect the networking device that is being configured with AutoInstall to the network and power it on.
-
The network has the IP connectivity necessary to permit the networking device to load configuration files from the TFTP server during the AutoInstall process.
-
A DHCP server is available on the network to provide IP addresses to networking devices that are using AutoInstall over a LAN connection.
Prerequisites for Cisco IOS Setup Mode
-
A terminal is connected to the console port of the device being configured.
-
You know the interfaces you want to configure.
-
You know the routing protocols you want to enable.
For information about routing protocols, see the Cisco IOS IP Routing Protocols Configuration Guide .
-
You know whether the device you are configuring will perform bridging.
-
You know whether the device you are configuring has protocol translation installed.
-
You have network addresses for the protocols being configured.
For information about network addresses, see the Cisco IOS IP Addressing Services Configuration Guide.
-
You have a password strategy for your network environment.
For information about passwords and device security, see “Configuring Security with Passwords, Privilege Levels, and Login User names for CLI Sessions on Networking Devices” in the Cisco IOS Security Configuration Guide .
-
You have or have access to documentation for the product you want to configure.
