Administrator Guide

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.
ipv6 address eui64
