no ipv6 dhcp guard

Parameters

N/A

Default Configuration

DHCPv6 Guard on a VLAN is disabled.

Command Mode

Interface (VLAN) Configuration mode

User Guidelines

DHCPv6 Guard blocks messages sent by DHCPv6 servers/relays to clients
received on ports that are not configured as a DHCPv6 server. Client messages or
messages sent by relay agents from clients to servers are not blocked. See the

device-role (IPv6 DHCP Guard)

command for details.

DHCPv6 Guard validates received DHCPv6 messages based on a DHCPv6 Guard
policy attached to the source port.

Examples

Example 1—The following example enables DHCPv6 Guard on VLAN 100:

switchxxxxxx(config)#

interface vlan

100

switchxxxxxx(config-if)#

ipv6 dhcp guard

switchxxxxxx(config-if)#

exit

Example 2—The following example enables DHCPv6 Guard on VLANs 100-107:

switchxxxxxx(config)#

interface range

vlan

100-107

switchxxxxxx(config-if-range)#

ipv6 dhcp guard

switchxxxxxx(config-if-range)#

exit
