If the switches are to be assigned a static IP address included in a specified configuration file (.text) or by a DHCP server, the entries in the *.setup file that assigns a specific configuration file and image to each switch has the following format: MAC_Address Config_File Image_File For example: 0180.c200.0010 switch-Y.text 1180.c200.0011 switch-Z.text PC7000vR.5.4.1.stk PC7000vR.5.4.1.stk After a line has been read and implemented by the Auto Configuration feature, it automatically adds "in-use" to the end of the line to ensure that the information is not used for the next switch. To replicate the entire USB auto configuration process, the "in-use" statements from the .setup file need to be removed. Then, if the process is restarted, the MAC address/IP address combinations will be ensured for any switch that has previously attempted upgrade and all other switch upgrades can take place as if for the first time. What Is the DHCP Auto Configuration Process? If the USB Auto Configuration fails or is not used, the switch can use a DHCP server to obtain configuration information from a TFTP server. DHCP Auto Configuration is accomplished in three phases: 1 Assignment or configuration of an IP address for the switch 2 Assignment of a TFTP server 3 Obtaining a configuration file for the switch from the TFTP server Auto Configuration is successful when an image or configuration file is downloaded to the switch from a TFTP server. NOTE: The downloaded configuration file is not automatically saved to startupconfig. You must explicitly issue a save request (copy running-config startupconfig) in order to save the configuration. Obtaining IP Address Information DHCP is enabled by default on the Out-of-Band (OOB) interface. It is disabled by default on VLAN 1, which is the default management VLAN and includes all switch ports as members. If an IP address has not been assigned, the switch issues requests for an IP address assignment. Auto Image and Configuration Update 379
