Mirror direction of mirroring-port. Once mirror direction was configured for a mirroring-port, it can not be changed unless the mirroring-port was removed from mirror group. If a mirror port is configured with two mirror directions 'outbound' and 'inbound', though it is functionally equal to 'both', it will be handled as two table items. If a mirror port is configured with mirror direction 'outbound' or 'inbound', or both of them, it will not be allowed to configure 'both', more details please refer to mirror group manual.
