Cisco IOS SPAN and RSPAN

Hi Alan,

Good question…only thing I could find is this document:

http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960x/software/15-0_2_EX/network_management/configuration_guide/b_nm_15ex_2960-x_cg/b_nm_15ex_2960-x_cg_chapter_0111.html#concept_A4AB227AC35840A1ACE51453EDBACD3E

a) It doesn’t specify anything about the number of interfaces, only the number of sessions.

b) For a single session, you specify a source + destination so that’s one session.

c) maximum of 4 (2 if switch is stacked with Catalyst 2960-S switches) source sessions and 64 RSPAN destination sessions. A source session is either a local SPAN session or an RSPAN source session.
