set port arp-inspection
set port arp-inspection
To set Address Recognition Protocol (ARP) inspection thresholds on a per-port basis, use the set port
arp-inspection command.
set port arp-inspection mod/port drop-threshold rate shutdown-threshold rate
Syntax Description
Defaults Both threshold rates are 0 packets per second.
Command Types Switch command
Command Modes Privileged.
Usage Guidelines If the number of packets exceeds the drop-threshold rate, the excess packets are dropped. The excess
packets are still counted toward the shutdown-threshold rate. If the number of packets exceeds the
shutdown-threshold rate, the port is shut down.
When the threshold rates are both at 0 packets per second, per-port rate limiting is not on.
Examples This example shows how to set the drop-threshold to 500 and the shutdown-threshold to 1000 for port
2/1:
Console> (enable) set port arp-inspection 2/1 drop-threshold 500 shutdown-threshold 1000
Drop Threshold=500, Shutdown Threshold=1000 set on port 2/1.
