2 U n i t e d N e t w o r k i n g 2 boot software the boot software is a program whose primary function is to:  load the OneOs binary in SDRAM memory boot parameters specify where the binary must be found:  in Flash  on the LAN  verify the binary checksum  uncompress the binary  execute the OneOs software boot software allows to load a OneOs binary from a LAN using FTP or TFTP the boot configuration is case-sensitive

3 U n i t e d N e t w o r k i n g 3 boot software auto-boot software  a router cannot reboot if the file /BSA/binaries/OneOs is invalid or not found  in that case the boot-process comes in a loop  the ‘auto-boot’ can be interrupted by pressing « CTRL+O » : <== Press CTRL+O to interrupt auto-boot

4 U n i t e d N e t w o r k i n g 4 boot parameter settings boot parameters: ParameterValues & formatMeaning boot deviceFastethernet0Ethernet interface for FTP/TFTP traffic processor number0not used host nameany stringhostname of server file name / file to load inet on ethernet (e)A.B.C.D.IP address of ethernet interface inet on backplane (b)-not used host inet (h)A.B.C.D.IP address of the server user (u)any stringFTP user name ftp password (pw)any stringFTP password flags (f)0x boot options target nameany stringlocal hostname startup script-not used other-not used

5 U n i t e d N e t w o r k i n g 5 boot menu help (1) boot help menu: commands Syntax : h or ? The commands ‘h’ or ‘?’ display the boot help menu:

6 U n i t e d N e t w o r k i n g 6 boot menu help (2) boot help menu: flags  the flag specifies how the "auto-boot" will be executed

7 U n i t e d N e t w o r k i n g 7 boot flags boot flags examples  flag structure: 0 x  when the boot process is stopped by « CTRL+O » the way the software will be loaded depends on the flag: 0x : boot from flash with countdown: /BSA/binaries/OneOS 0x : boot from flash without countdown: /BSA/binaries/OneOS 0x : boot from network via FTP with countdown 0x : boot from network via FTP without countdown 0x : boot from network via TFTP with countdown 0x : boot from network via TFTP without countdown 0: countdown 8: no countdown 0: FTP 8: TFTP 0: start from FLASH 1: start from network

8 U n i t e d N e t w o r k i n g 8 configuring boot parameters configuring / changing the boot flags  stop the boot process by « CTRL+O » [Boot Loader]: c '.' = clear field; '-' = go to previous field; ^D = quit boot device : FastEthernet0  processor number : 0  host name :  file name : C:\one180 c:\OneOS\ONEOS5-SIP.ZZZ  inet on ethernet (e) :  inet on backplane (b):  host inet (h) :  user (u) : oa test  ftp password (pw) (blank = use rsh): oa test  flags (f) : 0x  target name (tn) :  startup script (s) :  other (o) :  [Boot Loader]:

9 U n i t e d N e t w o r k i n g 9 booting from flash boot from flash  from [Boot Loader] prompt : use command " f " followed by software file location & file name file name must have extension.ZZZ example:

10 U n i t e d N e t w o r k i n g 10 booting with FTP (1) booting from network using FTP  flag: 0x or 0x  command « n » : load software in RAM  example:

11 U n i t e d N e t w o r k i n g 11 booting with FTP (2) booting from network using FTP  flag: 0x or 0x  command « g » : load software in flash and rename to OneOs  example:

12 U n i t e d N e t w o r k i n g 12 booting with TFTP booting from network using TFTP  set related flags: 0x or 0x  example:  command « n » loads software in RAM  command « g » loads software in flash
