Characteristics of Destination Ports
Each local SPAN session must have a destination port (also called a monitoring port) that receives a copy of
traffic from the source ports, VSANs, or VLANs. A destination port has these characteristics:
•
Cannot be a source port.
•
Cannot be a port channel or SAN port channel group.
•
Does not participate in spanning tree while the SPAN session is active.
•
Is excluded from the source list and is not monitored if it belongs to a source VLAN of any SPAN
session.
•
Receives copies of sent and received traffic for all monitored source ports.
•
The FEX interface cannot be a span destination.
Multiple SPAN Destinations
Local SPAN and SPAN-on-Drop sessions can support multiple destination ports. This allows traffic in a single
local SPAN session or a SPAN-on-Drop session also to be monitored and send to multiple destinations.
