Configuring IP Glean Throttling
Cisco NX-OS software supports glean throttling rate limiters to protect the supervisor from the glean
traffic.
You can enable IP glean throttling.
Note We recommend that you configure the IP glean throttle feature by using the hardware ip glean throttle
command to filter the unnecessary glean packets that are sent to the supervisor for ARP resolution for
the next hops that are not reachable or do not exist. IP glean throttling boosts software performance and
helps to manage traffic more efficiently.
BEFORE YOU BEGIN
Ensure that you are in the correct VDC (or use the switchto vdc command).
