Command Function
DES-7200(config)# dhcpv6-guard
rate-limit per-port pps
Configure the dhcpv6-guard rate-limit of the DHCPV6
packet on the port, ranging from 1 to 9999, 150 by
default.
DES-7200(config)# dhcpv6-guard
attack-threshold per-port pps
Configure the dhcpv6-guard attack threshold, ranging
from 1 to 9999, 300 by default.
When the DHCPV6 packet number on a port exceeds
the attack threshold, the CLI prompts and the TRAP
packets are sent.
DES-7200(config-nfpp)# end
Return to the privileged EXEC mode.
DES-7200# configure terminal
Enter the global configuration mode.
DES-7200(config)# interface
interface-name
Enter the interface configuration mode.
DES-7200(config-if)#nfpp dhcpv6-guard
policy per-port rate-limit-pps
attack-threshold-pps
Configure the rate-limit and attack threshold on the
specified interface.
rate-limit-pps: set the rate-limit threshold. The valid
range is 1-9999 and by default, it adopts the global
rate-limit threshold value.
attack-threshold-pps: set the attack threshold. The
valid range is 1-9999 and by default, it adopts the
global attack threshold value.
DES-7200(config-nfpp)# end
Return to the privileged EXEC mode.
DES-7200(config-if)# show nfpp
dhcpv6-guard summary
Show the parameter settings.
DES-7200# copy running-config
startup-config
Save the configurations.
Caution
The source MAC address-based rate limit takes precedence over port-based
rate limit.
