Performing Switch Setup Configuration

Restrictions for Performing Switch Setup Configuration

• The DHCP-based autoconfiguration with a saved configuration process stops if there is not at least
one Layer 3 interface in an up state without an assigned IP address in the network.
• Unless you configure a timeout, the DHCP-based autoconfiguration with a saved configuration
feature tries indefinitely to download an IP address.
• The auto-install process stops if a configuration file cannot be downloaded or it the configuration
file is corrupted.
Note The configuration file that is downloaded from TFTP is merged with the existing configuration in the
running configuration but is not saved in the NVRAM unless you enter the write memory or
copy running-configuration startup-configuration privileged EXEC command. Note that if the
downloaded configuration is saved to the startup configuration, the feature is not triggered during
subsequent system restarts.

Information About Performing Switch Setup Configuration

This chapter describes how to perform your initial switch configuration tasks that include IP address
assignments and DHCP autoconfiguration.

Switch Boot Process

To start your switch, you need to follow the procedures in the Cisco IE 2000 Switch Getting Started
Guide or the hardware installation guide for installing and powering on the switch and for setting up the
initial switch configuration (IP address, subnet mask, default gateway, secret and Telnet passwords, and
so forth).
The normal boot process involves the operation of the boot loader software, whic h performs these
activities:
• Performs low-level CPU initialization—Initializes the CPU registers, which control where physical
memory is mapped, its quantity and its speed.
• Performs power-on self-test (POST) for the CPU subsystem—Tests the CPU DRAM and the portion
of the flash device that makes up the flash file system.
