Use this procedure to configure and enable SSH Version 2 access on Cisco NCS 1001, and verify secure remote administration capability.

Enable secure remote access to the Cisco NCS 1001 management interface using SSH Version 2.

Use a terminal emulation program to establish an SSH connection to the management interface IP address for remote administration.

Before you begin

  • Install the ncs1001-k9sec package on Cisco NCS 1001. For details about package installation, see Install packages.

  • Generate the crypto key for SSH by using the crypto key generate dsa command.

Follow these steps to configure and enable SSH Version 2 access:

Procedure

1.

Enter the configuration mode.

Example:

RP/0/RP0/CPU0:ios# configure
2.

Use the ssh server v2 command to enable the SSH server to accept only SSHv2 client connections

Example:

RP/0/RP0/CPU0:ios(config)# ssh server v2
3.

Use the commit or end command.

  • Commit — saves the configuration changes and remains within the configuration session.

  • End — prompts you to save (Yes), discard (No), or stay in the session (Cancel).
4.

Use the show ssh session details command to verify that the SSH sessions are established.

Example:

RP/0/RP0/CPU0:ios# show ssh session details

SSH Version 2 server access is enabled, and you can verify established SSH sessions for remote administration.
