Configuration Guide 540
Configuring Network Security DHCP Snooping Configuration
Step 6 ip dhcp snooping decline rate
value
Enable the decline protect feature and specify the maximum number of Decline packets can
be forwarded per second on the port. The excessive DHCP Decline packets will be discarded.
value:
Specify the limit rate value of Decline packets. Seven options are provided: 0,
5,10,15,20,25 and 30 (packets/second). The default value is 0, which indicates disabling this
feature.

Return to privileged EXEC mode.
Step 8 copy running-config startup-config
Save the settings in the configuration file.
The following example shows how to configure port 1/0/1 as a trusted port, enable the MAC
verify feature, and set the limit rate as 10 pps and decline rate as 20 pps on this port:
Switch#configure
Switch(config)#interface gigabitEthernet 1/0/1
Switch(config-if)#ip dhcp snooping trust
Switch(config-if)#ip dhcp snooping mac-verify
Switch(config-if)#ip dhcp snooping limit rate 10
Switch(config-if)#ip dhcp snooping decline rate 20
Switch(config-if)#show ip dhcp snooping interface gigabitEthernet 1/0/1
Interface Trusted MAC-Verify Limit-Rate Dec-rate LAG
--------- ------- ---------- ---------- -------- ---
Gi1/0/1 Enable Enable 10 20 N/A
Switch(config-if)#end
Switch#copy running-config startup-config
3.2.3 (Optional) Configuring Option 82
Option 82 records the location of the DHCP client. The switch can add the Option 82 to the DHCP
request packet and then transmit the packet to the DHCP server. Administrators can check the
location of the DHCP client via option 82. The DHCP server supporting Option 82 can also set
the distribution policy of IP addresses and other parameters, providing more flexible address
distribution way.
