Aug 25, 2016 The following are the prerequisites for configuring the switch for secure shell (SSH): For SSH to work, the switch needs an Rivest, Shamir, and Adleman (RSA) public/private key pair. This is the same with Secure Copy Protocol (SCP), which relies on SSH for its secure transport. Jun 11, 2019 SW1 ( config)# crypto key generate rsa. How many bits in the modulus 512: 1024% Generating 1024 bit RSA keys, keys will be non-exportableOK Set the size of key to 1024 bits. If your Cisco Switch is running an older version of Cisco IOS image, then it is extremely recommended that you upgrade to latest Cisco IOS.
- Nov 23, 2011 How to enable SSH on a Cisco 800 series. Router# config term router(config)#crypto key generate rsa usage-keys label router-key The name for the keys will be: router-key Choose the size of the key modulus in the range of 360 to 2048 for your Signature Keys. Choosing a key modulus greater than 512 may take a few minutes.
- Config t crypto key generate rsa exit Then ssh to the router and complete the config. Or just enable telnet if you can get away with it. Config t vty 0 4 transport input ssh telnet exit I have a perl script that does this to reset enable passwords.
- Mar 30, 2020 Easy configure ssh on Cisco router or switch. For remote connection to router or switch, you need to enable ssh on Cisco router and configure ssh correctly. Easy configure ssh on Cisco router or switch. Configure the router to use RSA key pair with modulus size of 1024 bites for remote service authentication with “crypto key generate rsa.
- As of Cisco IOS Release 12.4(11)T, peer public RSA key modulus values up to 4096 bits are automatically supported. The largest private RSA key modulus is 4096 bits. Therefore, the largest RSA private key a router may generate or import is 4096 bits.
