Understanding How the Switch Management Interfaces Work

Catalyst 6500 series switches have three configurable IP management interfaces, the in-band (sc0 and
sc1) interfaces and the out-of-band management Serial Line Internet Protocol (SLIP) (sl0) interface.
The in-band (sc0 and sc1) management interfaces are connected to the switching fabric and participate
in all of the functions of a normal switch port, such as spanning tree, Cisco Discovery Protocol (CDP),
VLAN membership, and so forth. The out-of-band management interface (sl0) is not connected to the
switching fabric and does not participate in any of these functions.
