Syntax: show ipv6 dhcp-relay interface interfacetype
The interface type is interface type such as ethernet, POS, or VE and the specific port number.
Table 48 describes the fields from the output of the show ipv6 dhcp-relay interface command.
Output from the show ipv6 dhcp-relay interface command TABLE 48
Field Description
Destinations The DHCPv6 relay destination configured on the interface.
• Destination : The configured destination IPv6 address.
• OutgoingInterface : The interface on which packet will be relayed if the destination relay
address is link local or multicast.
Options The current information about DHCPv6 relay options for the interface.
• Interface-Id : The interface ID option indicating if the option is used or not.
• Remote-Id : The remote ID option indicating if the option is used or not.
Prefix Delegation
Notification This current information about the DHCPv6 Prefix Delegation for the interface.
• Interface: The name of the interface.
• Current - The number of delegated prefixes currently learned on the interface.
• Maximum - The maximum number of delegated prefixes that can be learned on the
interface.
• AdminDistance - The administrative distance used for prefixes learned on the specific
interface when added to IPv6 Static Route table.
Clearing the DHCPv6 delegated prefixes
To clear the DHCPv6 delegated prefixes for specific VRFs, use the clear ipv6 dhcp-relay delegated-
prefixes command at the privilege level.
device# clear ipv6 dhcp-relay delegated-prefixes vrf VRF1
Syntax: clear ipv6 dhcp-relay delegated-prefixes { vrf vrf-name } { X:X::X:X/M | all | interface
interface-id }
The vrfvrf-name parameter is used to clear the DHCPv6 delegated prefixes for a specific VRF. If this
parameter is not provided, then the information for the default VRF is cleared.
The X:X::X:X/M parameter is used to clear the specified delegated prefix and remove the corresponding
route permanently from the router.
The all parameter is used to clear all the delegated prefixes and remove the corresponding routes
permanently from the router for the VRF.
The interfaceinterface-id parameter is used to clear all the delegated prefixes and remove the
corresponding routes permanently from the router for the specified outgoing interface.
Clearing the DHCPv6 packet counters
To clear all DHCPv6 packet counters, use the clear ipv6 dhcp-relay statistics command at the
privilege level.
device# clear ipv6 dhcp-relay statistics
Clearing the DHCPv6 delegated prefixes
