4321 ver. 15.5(3)S4b - missing "ipv6 dhcp client" option??

[train_wreck]

I am having the same problem as the post here: https://community.cisco.com/t5/ipv6/quot-ipv6-dhcp-client-quot-missing-from-ios-xe-15-4/td-p/2734416

I have a 4321 that I am trying to configure IPv6 prefix delegation. The 4321 is the client to the ISP who provides IPv6 via prefix delegation.

In IOS I would configure this by entering the interface subconfig and then running "ipv6 dhcp client pd <NAME>". This option is unavailable. There is no client option available at all..... :

Cisco4321(config-if)#ipv6 dhcp ?
  framed  Framed-IPv6-Prefix allocation
  relay   Act as an IPv6 DHCP relay agent
  server  Act as an IPv6 DHCP server

Cisco4321(config-if)#

What's going on? Does the device support client prefix delegation? Have the commands changed in IOS-XE?

So you're saying I need to be on version 15.5.3.S7b ?

i checked that on one of my routers running that code and the options there , you could confirm further by checking the configuration guide for that release on the web site , but it looks to be there for me , im running appxk9,ipbase and seck9 license , it could be related to that too

I can't find any specific configuration guide for this firmware release. As far as I can tell, the command should be the same everywhere.

Here is my show license:

try the navigator below,different commands can be available in later releases and also with different licenses available , i haven't got that version but i cant confirm its in the one im running with those specific licenses ,you could easily test it with an upgrade and see if its a license required too or not
