Implementing Cisco IP Switched Networks (SWITCH v2-0) (#265)

A Cisco Catalyst switch that is prone to reboots continues to rebuild the DHCP snooping database. What is the solution to avoid the snooping database from being rebuilt after every device reboot?

A DHCP snooping database agent should be configured.
Enable DHCP snooping for all VLANs that are associated with the switch.
Disable Option 82 for DHCP data insertion.
Use IP Source Guard to protect the DHCP binding table entries from being lost upon rebooting.
Apply ip dhcp snooping trust on all interfaces with dynamic addresses.
