Purpose
Configures the sources and traffic direction in which
to copy packets. You can enter a range of Ethernet
ports, a port channel, an inband interface, a range of
VLANs, or a satellite port or host interface port
channel on the Cisco Nexus 2000 Series Fabric
Extender (FEX).
You can configure one or more sources, as either a
series of comma-separated entries or a range of
numbers.
You can specify the traffic direction to copy as
ingress, egress, or both.
Source VLANs are supported only in the
Note
ingress direction. Source FEX ports are
supported in the ingress direction for all
traffic and in the egress direction only for
known Layer 2 unicast traffic.
For a unidirectional session, the direction of the source
must match the direction specified in the session.
