Step 1 - Login to Site2-S1

The first device you will verify is your Site2-S1 switch. Login to your Site2-S1 switch using the copy command below and paste into your VSCode Terminal. When prompted, the password is cisco.123 .

If prompted to accept the RSA key fingerprint like below, type or copy yes then input the password above.

    The authenticity of host '10.3.3.17 (10.3.3.17)' can't be established.
    RSA key fingerprint is SHA256:xneE+2XnZozaXwC/FgeYMRKJ4UhZV4iZD6QCD1u7gi8.
    Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
    Warning: Permanently added '10.3.3.17' (RSA) to the list of known hosts.
