qns1. my original question was how do I find out if they are 'LRE', 2950c or 2950, so I know which ios to download :
- but I am not sure about '2950c' for eg ?
note: the reason for asking my original question was (also) because I thought using the wrong ios caused the 'tftpd32' timed out error I was receiving, but it was (not).
after adding port udp 69 to my firewall to allow 'inbound', this allowed me to use tftpd32 below and no longer receive the 'time out' error.
step 2
installed 'putty & tftpd32' on xp but same issue from tftpd32:
copy tftp flash - I got - error 2950...timed out

hi netman,
what I would like to know is how exactly do I update my ios .bin to .tar version and you have said:
"the tar version if the ios is meant to be used to update using the method above. you can do it from the cli but it's easier using the browser."
question 1. I have allowed port 69 via firewall now, but just so I know how do I update via the browser being the easier method ?

hi akinsd,
when looking on the cisco download site, I viewed the following ios version '2950c' so wanted to know what the (c) meant or is it just another version higher or lower ios ?

ok thanks for that info.
ASKER
sound advice.
Sorry for the late arrival.
The .tar contains the .bin file as well as other files to enable the web functionality. As long as the original update to this switch contains the web components, you can use the .tar to update the IOS and web components via the web interface.
If the content of flash only contains the .bin as well as the configs, then you're left with updating using the .bin OR you can use the cli with the .tar on a tftp server and the command:
archive tar /xtract tftp://{your tftp IP address}/{your .tar filename} flash:
If the web interface is unavailable because of deleted files, then the command above will restore everything with the new .tar image.

ios using: - c2950-i6k212q4-mz.121-22.E
step 1
link used to downloaded the ios (the reason for the download was because on my windows 2008 current single dc/ad/dns/dhcp server I installed 'putty' successfully & 'tftpd32' but below was my result so guessed possible image corruption:
download url:
https://software.cisco.com/download/release.html?mdfid=270568146&flowid=2394&softwareid=280805680&release=12.1.22-EA14&relind=AVAILABLE&rellifecycle=ED&reltype=latest
- ping master dc to switch - successful
- ping from switch to master dc - successful
- delete flash - successful
copy tftp flash - I got - error 2950...timed out
step 2
installed 'putty & tftpd32' on xp but same issue from tftpd32:
copy tftp flash - I got - error 2950...timed out
step 3
uninstalled 'tftpd32 & installed cisco tftp server v1.1':
hyper terminal - copy tftp flash - successful
hyper terminal - copy flash tftp - successful
note:
I have used the 'cisco navigator' and could not locate 12.1ea.bin so I am not sure...!!!??
I also downloaded the below 'tar':
c2950-i6q412-tar.121-22.EA
