Usage Guidelines
A source port (also called a monitored port) is a switched port that you monitor for network traffic
analysis. In a single local SPAN session, you can monitor source port traffic such as received (Rx),
transmitted (Tx), or bidirectional (both).
A source port can be an Ethernet port, port channel, SAN port channel, or a VLAN port. It cannot be a
destination port.
For ERSPAN, if you do not specify both, rx, or tx, the source traffic is analyzed for both directions.
