Parameters
client
: Sets the device role to DHCPv6 client.
server
: Sets the device role to DHCPv6 server.
Usage guidelines
The target interface or VLAN refers to the interface or VLAN to which a DHCPv6 guard policy is
applied. The device makes forwarding decisions based on the device role as follows:
•
Drops DHCPv6 replies received from the device with the device role of DHCPv6 client.
•
Forwards DHCP replies received from the device with the device role of DHCPv6 server only if
the packets pass the DHCPv6 guard check.
If the target interface or VLAN is attached to an authorized DHCPv6 server, set the device role to
DHCPv6 server for the authorized DHCPv6 server. If no authorized DHCP servers are attached to
the target interface or VLAN, set the device role to DHCPv6 client for devices attached to the target
interface or VLAN.
The
trust port
command has a higher priority than the
device-role
command. If you
configure both commands for a DHCPv6 guard policy, the
trust port
command takes effect.
Examples
# Set the role to DHCPv6 server for the device attached to the target interface or VLAN.
