PKI-based link encryption

We support PKI-based link encryption for interchassis links (ICLs) in Multinode High Availability. PKI provides a way of verifying the identity of a remote site by using a digital certificate. You can now generate and store node-specific PKI objects such as local keypairs, local certificates, and certificate-signing requests on both nodes. You can generate, view, and clear node-specific certificates using the CLI commands with the node-local option.
