Description (partial)

CCO documentation correction

Nexus 5500 can SPAN traffic > 1Gbps and the limitation outlined in the document is not valid:

"On the Nexus 5500 series, SPAN traffic is rate-limited to 1Gbps by default so the switchport monitor rate-limit 1G interface command is not supported."

Nexus 5500 only have the following restrictions in respect to SPAN:
SPAN is rate-limited to 5 Gbps for every 8 ports (one ASIC).
RX-SPAN is rate-limited to 0.71 Gbps per port when the RX-traffic on the port exceeds 5 Gbps.
