IBM N Series - Ipv6 Default Router Is; Burned in MAC Address

38 Accessing the management interface
3. To configure the static IP address, subnet mask, and default gateway, use the
following command:
serviceport ip ip-address netmask [gateway]
For example, to configure the management interface with an IP address of
192.168.2.23, a subnet mask of 255.255.255.0, and a default gateway of
192.168.2.1, enter the following command:
serviceport ip 192.168.2.23 255.255.255.0 192.168.2.1
4. Optionally, to manually configure the IPv6 address, prefix, and default
gateway, enter the following commands:
serviceport ipv6 address ipv6-address/prefix-length [eui64]
serviceport ipv6 gateway gateway
For example, to configure the management interface with an IPv6
address/prefix of 2001:DB8:132::3/32 and a default gateway of
2001:DB8:132::1/32, enter the following commands:
serviceport ipv6 address 2001:DB8:132::3/32
serviceport ipv6 gateway 2001:DB8:132::1
5. To verify the configured information, enter the following command:
(CN1610) #show serviceport
