user@host> show dhcp server binding routing-instance customer routing instance
• To display extended DHCP local server statistics:
user@host> show dhcp server statistics routing-instance customer routing instance

local server:
user@host> clear dhcp server binding routing-instance customer routing instance
• To clear all extended DHCP local server statistics:
user@host> clear dhcp server statistics routing-instance customer routing instance
