Usage Infomation
• SAA can configure up to two addresses. If any preferred prefix or valid timers time out,
the corresponding address are deprecated or removed. If an address is removed due
to a time-out, an address from the current unused prefix is used to create a new
address. If there are no remaining prefixes, the software waits to receive a new prefix
from the RA.
• If auto-configuration is enabled, all IPv6 addresses on that management interface are
auto-configured. Manual and auto-configurations are not supported on a single
management interface.
• Removing auto-configuration removes all auto-configured IPv6 addresses and the link-
local IPv6 address from that management interface.
• IPv6 addresses on a single management interface cannot be members of the same
subnet.
• IPv6 secondary addresses on management interfaces across a platform must be
members of the same subnet.
• IPv6 secondary addresses on management interfaces should not match the virtual IP
address and should not be in the same subnet as the virtual IP.
