4-8 CHAPTER 4: CONFIGURATIONNetwork Boot String Specifies the filename of the image to be downloaded from an RBCS orTFTP/FTP server and executed. This string can be up to 128 characterslong. The default is “_cs200 “ (without the quotation marks).If your boot protocol is System Load Protocol (SLP), do not modify thedefault network boot string.If your boot protocol is TFTP and your Address Discovery Protocol isLocal Information, you must change the default network boot string tothe complete pathname of the file you want to download. The default,“_cs200,” is not a valid filename. The pathname you enter depends onyour UNIX® platform or generic TFTP server. For example, the bootstring for a CS/2500 booting multiprotocol software version 6.2 from aDOS TFTP server would be “T25V62 “ (without the quotation marks).Boot Retries Specifies server behavior if a boot attempt fails. If you set “Try OneTime,” the server tries to boot only once. If you set “Try Forever,” theserver continues trying to boot until a suitable boot source is discovered.Boot Protocol Determines the file transfer protocol the communications server useswhen it downloads software from an RBCS or generic TFTP/FTP server.The choices are Bridge Transport Protocol (BTP), System Load Protocol(SLP), and Trivial File Transfer Protocol (TFTP).BTP is a 3Com proprietary load protocol. This protocol was formerlyused with 3Com Network Control Servers (NCSs). 3Com no longersupports NCS software, and you should not select this protocol. SLP is3Com’s implementation of the 802.1 standard System Load Protocol.TFTP is a file transfer protocol that is part of the TCP/IP protocol suite.If you are configuring your server to boot from an RBCS server, you canuse either SLP or TFTP. If you boot from a TFTP server, use TFTP.If you select SLP as your boot protocol, the server uses the file specifiedby Network Boot String as the boot source. You do not need toconfigure additional parameters. If you select TFTP, you need toconfigure several other parameters. These parameters are described inthe next section.CS2500BookFile : Configuration Page 8 Thursday, December 11, 1997 10:44 AM
