DHCP snooping, Arp inspect

I have a L2 LAN stack, 3750's.

If I add the following in this order:

Switch(config)# ip dhcp snooping
Switch(config)# ip dhcp snooping vlan 10
Switch(config)# ip arp inspection vlan 10

Port-Channel Trunk
Switch(config-if)# ip dhcp snooping trust
Switch(config-if)# ip arp inspection trust

int gi4/0/2
Switch(config-if)# ip dhcp snooping trust
Switch(config-if)# ip arp inspection trust

Is this safe to do on production device during day.

Well considering once you enable dhcp snooping all the ports are untrusted until you trust some of the ports. Otherwise, while I wouldn't recommend entering it during the day, it don't see why it would disrupt anything. The risk is yours to take. I would wait till off hours for any change though. Sometimes things can unexpectedly happen that you don't expect. Better to be safe than sorry.
