I have two Cisco Catalyst 2960-S 48-port switches 'stacked' using the Cisco FlexStack module. Originally I had to set them up using 'Express Setup', which I absolutly hate from my limited use of it.
I configured hostnames, ip addresses, and made sure the stack was functioning properly. I tested by plugging in a laptop and making sure it could open an internet page and all was well. I configured each switch exactly the same with the exception (obviously) of the hostname and IP. I then powered them OFF and installed the stacking module and they auto-configured themselves...
Before:
Switch-A (192.168.10.3)
Switch-B (192.168.10.4)
After:
Switch-A (192.168.10.3) Master 1
Switch-B Member 2
What I need and want to do now is setup remote access. If I have to go connect up with a console cable to configure that's fine, but I'm not sure if I need to...
If I open PuTTY and use Telnet to connect it states 'password required, but none set' and the PuTTY window closes.
If I open PuTTY and use SSH to connect it prompts me 'login as:'
If I press enter (@192.168.10.3's password:) it proceeds to prompt me for a password, which entering the password I used to setup the switch I receive 'access denied'.
I know I didn't configure SSH or Telnet for that matter when I initially set these up. I want to fix that now.
I want SSH (v2) enabled and I want to disable Telnet.
Any suggestions?
Aug 25, 2016 Switch (config)# crypto key generate rsa Enables the SSH server for local and remote authentication on the Switch and generates an RSA key pair. Generating an RSA key pair for the Switch automatically enables SSH. We recommend that a minimum modulus size of 1024 bits. When you generate RSA keys, you are prompted to enter a modulus length. Dec 24, 2019 I then ran the crypto key generate rsa command to generate another key pair and still got the same end date. I then checked the version of my other switches in the network to see why they were not alerting about certificate end date and they were using iOS15.2.6 or later while this switch is still on 15.2.2. How to configure SSH on Cisco IOS. #crypto key generate rsa The name for the keys will be: R1.NETWORKLESSONS.LOCAL Choose the size of the key modulus in the range. To enable SSH on device you need to have crypto image (or license supporting SSH). First, generate RSA keys for encyption. To generate them you need to specify hostname of device and any domain name. Router(config)#hostname Router-Branch Router-Branch(config)#ip domain-name grandmetric.labs Router-Branch(config)#crypto key generate rsa.
Oct 02, 2015 SSH Config and crypto key generate RSA command. Use this command to generate RSA key pairs for your Cisco device (such as a router). Keys are generated in pairs–one public RSA key and one private RSA key. If your router already has RSA keys when you issue this command, you will be warned and prompted to replace the existing keys with new keys. May 09, 2015 This article is going to shows the CCNA students to configure and enable telnet and ssh on Cisco router and switches. The Telnet is an old and non-secure application protocol for remote control services. You can configure telnet on all Cisco switches and routers with the following step by step guides.
