Q: How to setup a Ipv6 Dhcp server on controller?
A:
Please follow these command with an example setup
==================================================
Creating Dhcp pool
====================
(Aruba) (config)#service dhcpv6
(Aruba) (config)#ipv6 dhcp pool “DHCPv6”
(Aruba) (config-dhcpv6)#dns-server <server ip>
(Aruba) (config-dhcpv6)#lease 0 12 0 0
(Aruba) (config-dhcpv6)#network 2500:abcd:1234:dead::/64
Creating and interface and mapping the server
============================================
(Aruba) (config)#interface vlan 3
(Aruba) (config-subif)#ipv6 address 2500:abcd:1234:dead::1/64
(Aruba) (config-subif)#ipv6 dhcp server “DHCPv6” < Dhcp pool name>
Aruba) (config-subif)#!ipv6 nd ra enable
Aruba) (config-subif)#!ipv6 nd ra preference high
Aruba) (config-subif)#!ipv6 nd ra managed-config-flag
Aruba) (config-subif)#!nd ra prefix 2500:abcd:1234:dead::/64
(Aruba) (config-subif)#!
(Aruba) (config)# ipv6 dhcp excluded-address fdd7:b215:19cb:4552::25 fdd7:b215:19cb:4552::fe
ipv6 dhcp excluded-address 2500:abcd:1234:dead::50 2500:abcd:1234:dead:ffff:ffff:ffff:fffe
Few points to be noted
===============
- If you are not receiving an ip even after following the steps please check if the Network ip and interface ip are in the right subnet.
-Check the excluded ip are right
-Check the dhcp pool name is correctly mapped to the interface
