Check the SSH version (how many RSA bits are you generating?)

Check the cabling and NICs

Hi Ajith,

Please configure like below in your router to enable SSH.

Configure the Hostname on the Switch or Router
Router(config)# hostname MyRouter

Configure the Domain name for the Cisco Switch or Router
MyRouter(config)# ip domain-name MyDomain

Generate a RSA Key Pair
MyRouter(config)# crypto key generate rsa

Set the SSH Negotiation phase timeout interval (in seconds)
MyRouter(config)# ip ssh time-out 120

Set the Maximum retry attempts
MyRouter(config)# ip ssh authetication-retries 3

To change the default port for SSH (default is 22) connection
MyRouter(config)# ip ssh port 3536

MyRouter(config)# line vty 0 4
MyRouter(config)# transport input ssh

MyRouter# wr mem
To see the status of the SSH on the Cisco switch or the router

MyRouter# show ip ssh
SSH Enabled – version 1.5

Authentication timeout: 120 secs; Authentication retries: 3

To view the status of SSH connections
MyRouter# show ssh
