Does the Nexus 7700 with 8.0.1 firmware support DHCPv6 relay functionality (like ipv6 dhcp relay destination a:b:c:d:e:f:g:h on C6500)?

Hi,

If you check column 3 of the Table 19 of the following link it is supported

Hi,

Thank you for your reply and sharing the document.

Showing as supported but  ipv6 dhcp relay destination 2620:0:1AA0:8070:1:8:1:2 command is not available but the below command is available.

IIC-ENG-N7K-CORE(config-if)# ipv6 dhcp relay ?
address                   Configure DHCPv6 server relay address
source-interface      Configure source interface for DHCPv6 relay

IIC-ENG-N7K-CORE(config-if)# ipv6 dhcp relay address ?
A:B::C:D                    IPv6 server address

Is the equivalent command ipv6 dhcp relay address 2620:0:1AA0:8070:1:8:1:2 in nx-os.

Thanks in advance.

Regards,

Ashok

Hi Ashok,

As per the documentation for NX-OS for Nexus 7K

[no] ipv6 dhcp relay address IPv6-address [use-vrf vrf-name] [interfaceinterface] Example: switch(config-if)# ipv6 dhcp relay address FF02:1::FF0E:8C6C use-vrf red

Configures an IP address for a DHCPv6 server to which the relay agent forwards BOOTREQUEST packets received on this interface. Use the use-vrf option to specify the VRF name of the server if it is in a different VRF and the other argument interface is used to specify the output interface for the destination. The server address can either be a link-scoped unicast or multicast address or a global or site-local unicast or multicast address. The interface option is mandatory for a link-scoped server address and multicast address. It is not allowed for a global or site-scoped server address. To configure more than one IP address, use the ipv6 dhcp relay address command once per address.

Hi,

Thanks a lot for your help. You have saved lot of my time.

int vlan 10

ipv6 dhcp relay destination 2620:0:1AA0:8070:1:8:1:2

I have entered the above commands as we are not using VRF concept.

Hi,

I am sorry. The above command is from Cisco Catalyst switch.

The below command is the equivalent command in nx-os. 

int vlan 10

ipv6 dhcp relay address 2620:0:1AA0:8070:1:8:1:2

Thanks,

Ashok

That's fine Ashok, you can always search for the exact command in the Config or CLI guide for the product in question, its very rare that the command would not be listed. If it is not then probably it requires investigation whether the command is deliberately removed/changed or if it is a documentation bug.
