Defaults None Command Mode EXEC Usage Information This command clears the dynamic entries in the DHCP snooping binding table. CAUTION: Clearing the DHCP snooping binding table using the clear ip dhcp snooping binding command also clears the SAV and DAI entries on the system. This affects the traffic from clients that are connected to the DHCP snooping-enabled VLANs. Example (Global) OS10# clear ip dhcp snooping binding Example (MAC) OS10# clear ip dhcp snooping binding mac 04:56:79:86:73:fe Example (Port Channel) OS10# clear ip dhcp snooping binding mac 04:56:79:86:73:fe vlan 100 portchannel 10 Supported Release 10.5.0 or later or later ip dhcp snooping (global) Enables DHCP snooping globally. Syntax ip dhcp snooping Parameters None Defaults Disabled Command Mode CONFIGURATION Usage Information When you enable this feature, the switch begins to monitor all transactions between DHCP servers and DHCP clients and use the information to build the DHCP snooping binding table. If you disable DHCP snooping, the system removes the DHCP snooping binding table. Source Address Validation and Dynamic ARP Inspection entries are also removed. This command is accessible to users with sysadmin and secadmin roles. The no version of this command disables DHCP snooping globally.
