3550 IOS image and SSH

Help..does the C3550 Software (C3550-I9Q3L2-M)support SSH V2 clint?

Hi,

To use SSH you need a cryptographic (encrypted) IP services image i.e the enhanced multilayer software

image [EMI]) installed on your switch.

The image you have is a SMI image (standard multilayer image) and doesnot support that feature.

It would be someting like

c3550-i5k2l2q3-mz.121-22.EA5.bin

HTH,

You can get the SMI Crypto image (c3550-ipbasek9-mz.122-25.SEC.bin or c3550-i9k2l2q3-mz.121-22.EA5.bin) so you don't need to pay for the EMI upgrade.

The Crypto image is a no-cost upgrade, although obviously you can't install the EMI image over an SMI one without the appropriate license.
