Configuring Rule-Based Span - Cisco Nexus 7000 Series Configuration Manual

Configuring SPAN
For Layer 3 multicast traffic, SPAN replication occurs on the egress module. If traffic is multicasted to
Note
multiple egress modules, you could capture multiple SPAN copies for each packet (that is, one copy from
each egress module).
Before You Begin
Ensure that you are in the correct VDC (or use the switchto vdc command).

Configuring Rule-Based SPAN

You can configure filters for ingress or egress SPAN traffic based on a set of rules. A simple filter has only
one rule, and multiple fields or conditions can be added to this rule. The packets are spanned only if all
conditions are met.
Before You Begin
Ensure that you are in the correct VDC (or use the switchto vdc command).

specifies the SPAN session for which the source
rate limit is to be configured.
Configures the multicast best effort mode for the
specified SPAN session.
(Optional) Displays the status of SPAN sessions,
