1. A method for implementing traffic mirroring for network telemetry, the method comprising:
identifying network traffic at a network appliance that is to be subjected to traffic mirroring for network telemetry; and
selecting from available options of:
transmitting enhanced mirrored network traffic from the network appliance to a collector, wherein the enhanced mirrored network traffic is generated at the network appliance by at least one of compressing and encrypting the network traffic; and
transmitting mirrored network traffic from the network appliance to the collector without compressing or encrypting the network traffic;
wherein the enhanced mirrored network traffic is generated to include a header field that indicates whether mirrored network traffic is compressed;
wherein the header field is in a reserved field of an Encapsulated Remote Switch Port Analyzer (ERSPAN) header.
