Upgrade switch IOS to support SSH

[johnlloyd_13]

hi,

can someone advise what's the 'minimum' IOS to support SSH on these switches.

these switches have 32 MB flash on them.

WS-C2960-24TC-L   C2960-LANBASE-M 12.2(25)SEE2

WS-C3750G-24PS   C3750-IPBASE-M 12.2(35)SE5

WS-C3750G-48PS   C3750-IPBASE-M 12.2(35)SE5

To support SSH, IOS filename should have "k9" in the filename (example:  "c3560c405ex-universalk9-mz.152-2.E7").  Download the crypto version of the IOS.

pre,

i've checked cisco.com download page.

can you confirm IOS below if it's correct before i download them? these are TAC recommended IOSs (with star icon).

c2960-lanbasek9-mz.122-55.SE11.bin

c3750-ipbasek9-mz.122-55.SE11.bin

doesWS-C3750G-24PS IOS same 'cut' with  WS-C3750G-48PS?

Filenames are correct but why upgrade using the BIN file?  I recommend download the TAR file and use the "archive download-sw" script to automate the upgrade.

Yes.  It's the same.

hi,

i'm not a fan of 'automated' upgrade.

i would prefer the old and 'controlled' way of uprading a switch.

i'll go ahead and do the upgrade.

thanks for your help!
