SCP configuration example based on Suite B algorithms
Network requirements
As shown in Figure 112:
• Switch A acts as an SCP client (SSH2).
• Switch B acts as the SCP server (SSH2), and it uses publickey authentication.
• Switch B uses the following algorithms for the algorithm negotiation with the SCP client:
Key exchange algorithms ecdh-sha2-nistp256 and ecdh-sha2-nistp384.
Encryption algorithms aes128-gcm and aes256-gcm.
Public key algorithms x509v3-ecdsa-sha2-nistp256 and x509v3-ecdsa-sha2-nistp384.
Configure Switch A to establish an SCP connection to Switch B based on the Suite B algorithms.
After the connection is established, you can log in to Switch B from Switch A to transfer files between
switches as an administrator.
