Cisco declared the Catalyst 2960 (non-S, non-Plus) End-of-Support on April 30, 2018. The final suggested image for the 2960 platform was actually 12.2(55)SE, but 12.2(44)SE6 is far older.
Symptom: crypto key generate rsa fails or SSH login hangs.
Cause: Insufficient entropy or missing ip domain-name.
Fix:
ip domain-name lab.local
crypto key generate rsa modulus 1024
ip ssh version 2
(Note: 2048-bit keys are not supported in this IOS version.)
Running c2960-lanbasek9-mz.122-44.se6.bin today is a security paradox.
The Good: Because k9 is included, you can enable ssh version 2 and disable Telnet. You can implement basic port security and DHCP snooping.
The Bad: The last security patches for 12.2(44)SE6 were released around 2015. The switch does not support:
Furthermore, these switches have 32 MB of flash and 64 MB of RAM. Loading this bin file (approx 5.4 MB) leaves very little room for anything else. You cannot run crypto features like IPsec VPNs on this image; the "k9" refers only to management encryption.
