To display the currently configured reload mode for a switch running BMP version 2.0, enter the show reload-type or show bootvar command. FTOS#show reload type Reload-Type : config-download : dhcp-timeout : jump-start [Next boot :jump-start] enable 10 FTOS#show bootvar . . content truncated.. Reload Mode = jump-start File URL = tftp:/30.0.0.1/FTOS-SE-8-3-8-17.bin Note: If a switch enters a loop while reloading in Jumpstart mode because it continuously tries to contact a DHCP server and a DHCP server is not found, connect to the switch using the console terminal and enter the stop jump-start command to interrupt the repeated discovery attempts. The startup configuration file stored in the local flash on the switch is loaded and the auto-configuration mode is automatically changed to Normal reload, i.e., BMP is disabled. Jumpstart mode Jumpstart (BMP) mode is the default boot mode configured for a new switch arriving from Dell Force10. This mode obtains the FTOS image and configuration file from a network source (DHCP server and file server). DHCP Server DHCP Configuration You must first configure an external DHCP server before you can use the Jumpstart mode on a switch. Configure the DHCP server with the set of parameters described below for each client switch. Refer to the FTOS Configuration Guide: Dynamic Host Configuration Protocol chapter for detailed information. The DHCP server is configured to assign an IP address to the switch and specify the files to download. One or more of the following parameters must be configured on the DHCP server. • Boot File Name: The FTOS image to be loaded on the switch. The boot file name is expected to use Option 67 or the boot filename in the boot payload of the DHCP offer. If both are specified, Option 67 will be used. • Configuration File Name: The configurations to be applied to the switch. The configuration file name is expected to use Option 209. • File Server Address: The server where the Image and Configurations file are placed. The address is assumed to be a TFTP address unless it is given as a URL. The switch supports TFTP, HTTP, and FTP protocols, as well as files stored in Flash and external USB memory. If TFTP is used, you can add Option 66 or Option 150. • Domain Name Server: (Optional.) The DNS server to be contacted to resolve the hostname through Option 6. • IP Address: Dynamic IP address for the switch. This is used only for file transfers. Bare Metal Provisioning 2.0 | 213
