- Set the Allow Remote Access to Yes.
- Set the Allow Remote Login to Yes.
- Set the Allow Remote Shell to Yes.
- Set the Allow Remote Access to Yes.
- Click Apply to save the changes.
Step 5: Verify SSH Configuration
To verify that SSH is enabled on your Cisco Switch, follow these steps:
- Log in to the switch using the admin username and password.
- Navigate to System > Security > SSH.
- Verify that the SSH Port is set to 22 (default) and the SSH Username is set to root (default).
- Verify that the SSH Password is set to a strong password (default).
- Verify that the Allow Remote Access is set to Yes.
Troubleshooting SSH on Cisco Switch
If you encounter any issues with SSH on your Cisco Switch, follow these troubleshooting steps:
- Check the switch’s logs for any error messages related to SSH.
- Verify that the switch’s IP address is correct and that it is reachable from the remote host.
- Check that the switch’s firewall is enabled and that it is configured to allow SSH traffic.
- Verify that the switch’s SSH port is not blocked by any firewalls or network devices.
