Detailed statistics 
The DHCP Detailed Statistics page provides statistics for DHCP snooping. Note that 
the normal forward per-port TX statistics are not increased if the incoming DHCP 
packet is done by a L3 forwarding mechanism. Clearing the statistics on a specific port 
may not affect global statistics since it gathers a different layer overview.
