On the source vRouter, traffic from source interfaces is mirrored and prepended by Type II or Type III headers. These headers are defined in the IETF draft proposal.
Port mirroring is enabled when the session type and the destination interface for the session are configured. For ERSPAN sessions, the ERSPAN header type and identifier must also be configured.
Use the set form of the command to define the ERSPAN header type.
Use the delete form of the command to delete the ERSPAN header type.
Use the show form of the command to show the ERSPAN header type for a port monitoring session.
