Display DHCPv6 Relay Information

You can use show commands to display information about DHCP relay statistics, relay addresses for a device, and relay addresses for an interface.

Procedure

  1. Access privileged EXEC mode on a device where DHCPv6 relay is configured.
  2. Display all DHCP relay addresses configured on the device.
    device# show ipv6 dhcp relay address
    DHCPv6 unique identifier(DUID): 0102f8f10027f8d43dfb
    Interface           Relay Address           VRF Name            Outgoing Interface
    ---------           -------------           --------            ------------------
    eth 1/17             2002::10               default-vrf
    eth 1/17             2000::10               default-vrf         eth 0/9
    eth 1/17             2019::10               test                ve 102
    ve 94                2011::10               default-vrf
    
  3. Display all DHCP relay addresses configured for a specific interface on the device.
    device# show ipv6 dhcp relay address interface ethernet 1/40
    DHCPv6 unique identifier(DUID): 01021025768ef804e005
    Interface           Relay Address            VRF Name            Outgoing Interface
    ---------           -------------            --------            ------------------
    Eth 1/40             2019::10                default-vrf
    
  4. Display statistics such as the number of packets dropped, received, and sent.
    device# show ipv6 dhcp relay statistics
