By default, sessions are created in the shut state. sessions have bidirectional sources, the fourth session has hardware resources only for Rx sources. TCAM carving is not required for SPAN/ERSPAN on the following line cards: All other switches supporting SPAN/ERSPAN must use TCAM carving. Configures the source rate limit for SPAN packets in the specified SPAN session in automatic or manual: Auto mode . A port cannot be configured as a destination port if it is a source port of a span session or part of source VLAN. The no form of the command enables the SPAN session.
