show monitor session

Usage Guidelines			The erspan-destinationand erspan-sourcekeywords are not supported on Catalyst 6500 series
			switches that are configured with a Supervisor Engine 2.
			In releases prior to Release 12.2(18)SXF, ERSPAN is supported on Catalyst 6500 series switches that
			are operating in compact switch fabric module functionality switching mode only.
			Release 12.2(18)SXF and later releases support ERSPAN in any switch fabric module functionality
			switching mode.
			If the switch fabric module functionality switching mode is set to compact, the output of the show
			commands display “dcef mode” for fabric-enabled modules with DFC3 installed and display “fabric
			mode” for other fabric-enabled modules.
			If the switch fabric module functionality switching mode is set to truncated, the output of the show
			commands display “fabric mode” for all fabric-enabled modules.
			When entering a range of sessions, use a dash (-) to specify a range and separate multiple entries with a
			comma (,). Do not enter spaces before or after the comma or the dash.
			You can enter multiple ranges by separating the ranges with a comma.
			If you enter the show monitor session command without specifying a session, the information for all
			sessions is displayed.
