WS-C6509-E Boot

[actkillerby]

Good morning

I have been looking at grading the IOS version on our 6509-E however there is not enough space on disk:0 to upgrade to the version I need to install. The question I would like to ask is - is it possible to boot the IOS from a TFTP server? If this is possible what configuration do I need on the 6509 to enable this. How does the 6509 know about the TFTP server as an IOS is not installed and therefore it will not have a network configuration.

Thanks

Easy, UPGRADE the CF. 

All my Cisco routers ISR 1 and Sup720 have 2 Gb CF.  Please be aware that Cisco does NOT sell 2 Gb CF.

is it possible to boot the IOS from a TFTP server?   Yes it is possible

  How does the 6509 know about the TFTP server as an IOS is not installed? it will know by this command: boot system tftp imagename ip address of tftp server { TFTP server must be reachable from switch and required ports must be oepend on the server)

Ex:

Enter configuration commands, one per line.  End with CNTL/Z.
HOCRSW1(config)#boo
HOCRSW1(config)#boot sy
HOCRSW1(config)#boot system ?

  WORD   TFTP filename or URL
  flash  Boot from flash memory
  ftp    Boot from a server via ftp
  mop    Boot from a Decnet MOP server
  rcp    Boot from a server via rcp
  tftp   Boot from a tftp server

HOCRSW1(config)#boot system tftp ?

  WORD  System image filename

HOCRSW1(config)#boot system tftp image ?
  Hostname or A.B.C.D  Address from which to download the file
 

HOCRSW1(config)#boot system tftp image 192.168.1.1 ?
