Why each option
To enable an ERSPAN tunnel on the destination, the `erspan-id` command must be configured to match the ID used by the source.
The `origin ip address` command is used on the ERSPAN source to specify its IP address, not on the destination.
The `erspan-id` takes an integer as an argument, not an IP address.
While `no shut` is used to enable interfaces or features, the `erspan-id` command is specifically required to define and associate the ERSPAN session for the tunnel to function.
For an ERSPAN tunnel to be established and enabled between a source and destination, both ends must be configured with a matching `erspan-id`, which is a numerical identifier for the ERSPAN session.
