Configuring Multiple SPAN Sessions on a SPAN Destination Port

BEFORE YOU BEGIN
Ensure that you are in the correct VDC (or use the switch to vdc command).
Before You Begin
With the introduction of multiple SPAN sessions, it is important to share the destination interface across
multiple SPAN sessions, which not only reduce the N7K hardware cost of the SPAN sessions and the traffic
monitoring equipment, it can also simplify the overall network connections.
• Rate limiter 'auto' mode is not allowed with span session(s) having shared span destination port(s).
• The 'manual' mode is recommended when the rate limit is required for individual SPAN session.
