View

Parameters
total: Sets the maximum number of total arbitrary ARP packets that can be sent to the
CPU in a unit of time. (There is no limit on source and destination IP addresses in ARP
packets.)
local: Sets the maximum number of locally-terminated ARP packets (packets having
the same source IP address and using the IP address of the current switch as their
destination IP address) that can be sent to the CPU in a unit of time.
through: Sets the maximum number of pass-through ARP packets (packets having the
same source IP address and not using the IP address of the current switch as their
destination IP addresses) that can be sent to the CPU in a unit of time.
limit-value: Maximum number of a type of ARP packets that can be sent to the CPU in a
unit of time. When local or total is adopted, this argument ranges from 1 to
4294967295; when through is adopted, the value ranges from 0 to 4294967295.
Description
Use the arp source-suppression limit command to set the maximum number of a
type of ARP packets that can be sent to the CPU in a unit of time.
Use the undo arp source-suppression limit command to restore the default setting.
The default setting varies with the type of ARP packets.
z When total is adopted in the command, the default setting is 100.
z When local is adopted in the command, the default setting is 3.
z When through is adopted in the command, the default setting is 3.
Make sure your setting for total is greater than the settings for local and through.
