We have 3 edge stacks, all dhcp is handled by a DHCP server attached to our core 8810s.
For example, on edge stack IDF01 for vlan ENG, the configuration would look like this:
configure trusted-servers vlan ENG add server 172.16.5.50 trust-for dhcpserver
enable ip-security dhcp-snooping vlan ENG ports all violation action drop-packet
Does that look correct?
