OL-29434-01
Purpose
Enters global configuration mode.
Configures protocol storm protection for ARP, IGMP, or DHCP.
For value, specifies the threshold value for the number of packets per
second. If the traffic exceeds this value, protocol storm protection is
enforced. The range is from 5 to 50 packets per second.
(Optional) Enables error-disable detection for protocol storm
protection. If this feature is enabled, the virtual port is error disabled.
If this feature is disabled, the port drops excess packets without error
disabling the port.
(Optional) Configures an auto-recovery time (in seconds) for
error-disabled virtual ports. When a virtual port is error-disabled, the
switch auto-recovers after this time. The range is from 30 to 86400
seconds.
Returns to privileged EXEC mode.
