IPv6 Addressing Configuration
Enabling DHCPv6
To view the current IPv6 DHCPv6 settings per-VLAN, use show run.
To view all currently configured IPv6 unicast addresses, use the following:
show ipv6 (Lists IPv6 addresses for all VLANs configured on the switch.)
show ipv6 vlan < vid > (Lists IPv6 addresses configured on the VLAN.)
For more information, refer to “View the Current IPv6 Addressing Configura-
tion” on page 4-21.
Operating Notes
If multiple DHCPv6 servers are available, the switch selects a server based
on the preference value sent in DHCPv6 messages from the servers.
The switch supports both DHCPv4 and DHCPv6 client operation on the
same VLAN.
DHCPv6 authentication and stateless DHCPv6 are not supported in soft-
ware release K.13.01.
With IPv6 enabled, the switch determines the default IPv6 router for the
VLAN from the router advertisements it receives. (Refer to “Default IPv6
Router” on page 4-28.)
— Continued from the previous page. —
After verification of uniqueness by DAD, an IPv6 address
assigned to the VLAN by an DHCPv6 server is set to the
preferred and valid lifetimes specified in a router advertise-
ment received on the VLAN for the prefix used in the assigned
address, and is configured as a preferred address. (Refer to
the section titled “Address Lifetimes” on page 4-32.)
[rapid-commit]: Expedites DHCP configuration by using a two-
message exchange with the server (solicit-reply) instead of the
default four-message exchange (solicit-advertise- request-
reply).
Default: Disabled
The no form of the command removes the DHCPv6 option from
the configuration and, if no other IPv6-enabling command is
configured on the VLAN, disables IPv6 on the VLAN. (Refer to
“Disabling IPv6 on a VLAN” on page 4-16.)
