Configuring an ERSPAN Source Session

You can configure an ERSPAN session on the local device only. By default, ERSPAN sessions are created
in the shut state.
For sources, you can specify Ethernet ports, port channels, the supervisor inband interface, and VLANs (ingress
only). A single ERSPAN session can include mixed sources in any combination of Ethernet ports, VLANs,
or the inband interface to the control plane CPU.
For traditional sessions, you can configure the sessions without specifying the direction of the traffic.
Note ERSPAN does not monitor any packets that are generated by the supervisor, regardless of their source.
