CREATING PORT MAPS
This chapter describes how to create port maps in the web UI and CLI interfaces. Port maps route data between
TAP ports and must be configured for every TAP that you set up. The chapter covers the following major topics:
• About port maps, page 47
• Creating port maps, page 49
• Typical map configurations, page 52
About port maps
Port maps determine how tapped traffic within the SmartNA-X system flows from source port to destination port.
Maps that originate from the same source port are independent of one another, thus, traffic flowing along a map is
treated entirely separately from other maps originating from the same source. Multiple maps between the same
ports can also be created, although in this case the system only delivers one copy of the packet. Filters can be
applied to maps to screen which packet types reach the destination port(s). See Chapter 8,“Using Packet Filters”
for information on setting up and using filters.
SmartNA-X supports many-to-one maps (aggregation maps), and one-to-many maps (splitting map). Many-to-
many maps are not explicitly allowed, although the same effect can be achieved by setting up multiple aggregations
and/or multiple replications.
