About Rate Limits

Rate limits can prevent redirected packets for exceptions from overwhelming the supervisor module on a
Cisco NX-OS device. You can configure rate limits in packets per second for the following types of redirected
packets:
• Access-list log packets
• Bidirectional forwarding detection (BFD) packets
• Catch-all exception traffic
• Fabric Extender (FEX) traffic
• Layer 3 glean packets
• Layer 3 multicast data packets
• SPAN egress traffic—For this option only, you can configure rate limits in kilobits per second.
