I'm unable to configure the crypto configuration on a Cisco router 4321.

How to manually enable an HSEC-K9 license on a Cisco 4321 router?

@R Manjunatha 

Try the commands

config t

license accept end user agreement

license boot level securityk9

save and reload

The required command is:

conf t

license feature hseck9

end

write mem

Reading again the question - the problem is not having the security license enabled on the box, in which case @Flavio Miranda provided the correct answer.

The HSEC-K9 license is to enable higher throughput on the router and a greater number of IPSEC tunnels.
