ACL to allow N Series Switch DHCP
I have dhcp service running on a couple different N series switches and it works fine without any ACLs applied. When I start adding ACLs in order to restrict general traffic the DHCP service on the switch is no longer handing out IPs.
What sort of permit lines should I be looking to add to allow the switch to hand out IPs to a VLAN on that switch?

Hi,
Just to check, if the ACL allow DHCP traffic between the switch and the devices requesting IP addresses. By permitting UDP traffic on ports 67 and 68 (bootps and bootpc), the switch will be able to hand out IPs to the VLAN while still applying the ACL restrictions for other types of traffic.
permit udp any eq bootps any eq bootpc
permit udp any eq bootpc any eq bootps
