How do I upgrade an IOS tar file on a 2950 Catalyst switch? (#10854)
This is a supplement to the question already answered: "How do I upgrade/backup a Cisco IOS to my computer?" 1) In order to transfer the tar file you need a TFTP program. One example is located at jounin.net. When you are done downloading the tar file confirm the md5. 2) Issue dir flash: to verify you have enough space. SW1#dir flash: Directory of flash:/ 2 -rwx 3081999 Apr 14 1993 22:52:00 +00:00 c2950-i6q4l2-mz.121-22.EA1 .bin 3 -rwx 1390 Apr 14 1993 22:52:40 +00:00 config.text 4 -rwx 5 Apr 14 1993 22:52:40 +00:00 private-config.text 7741440 bytes total (4656128 bytes free) SW1# 3) You will probably want to delete your old ios image especially if you don't have much space left. SW1#delete flash:c2950-i6q4l2-mz.121-22.EA1.bin Delete filename [c2950-i6q4l2-mz.121-22.EA1.bin]? Delete flash:c2950-i6q4l2-mz.121-22.EA1.bin? [confirm] SW1# 4) You may want to delete any old html files if you have some old ones: delete flash:html/* 5) Issue the command to start the extraction process: archive tar /xtract tftp://10.10.10.3/c2950-i6q4l2-tar.121-22.EA1.tar flash: SW1#archive tar /xtract tftp://10.10.10.3/c2950-i6q4l2-tar.121-22.EA1.tar flash: Loading c2950-i6q4l2-tar.121-22.EA1.tar from 10.10.10.3 (via Vlan1): !
