auto-sense isis hello-auth type hmac-sha-256

Configures HMAC-SHA256 authentication type for IS-IS hello packets on ports that are operating in Auto-sense mode. With SHA-256 authentication, the switch adds an HMAC-SHA256 digest to each Hello packet. The switch that receives the Hello packet computes the digest of the packet and compares it with the received digest. If the digests match, the receiving switch accepts the packet. If the digests do not match, the receiving switch discards the packet.
