dhcp snooping requires reload?

[baselzind]

do i need a reload after applying dhcp snooping and applying dhcp snooping trust on a interface for the configuration to take effect?

Enabling IP DCP snooping does not require reload, but reqires, at least, command ip dhcp snooping to enable snooping globally. Check curent state of IP DHCP snooping by issuing command

show ip dhcp snooping

Hi

No, it does not required reload to take effect, but the mandatory commands lines are:

ip dhcp snooping  

ip dhcp snooping vlan <set up the vlans to be applied> ; once you have configured this line, it will enable DHCP snooping otherwise it will not be applied to none vlan. 

no ip dhcp snooping information option ; recommended to be disabled.

ip dhcp snooping trust ; it must be  configured on the interface toward the DHCP servers, usually it is configured on the trunk interfaces facing to the Distribution or Core switches.

*Note: Ip dhcp snooping is recommended to be configured on the access switches only.

Hope it is useful
