Usage Infomation
• SAA can congure up to two addresses. If any preferred prex 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 prex is used to create a new address. If there are no remaining prexes, the software waits to receive
a new prex from the RA.
• If auto-conguration is enabled, all IPv6 addresses on that management interface are auto-congured. Manual
and auto-congurations are not supported on a single management interface.
• Removing auto-conguration removes all auto-congured 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
Congure an IPv6 address to an interface.
Syntax
ipv6 address {ipv6-address prefix-length}
To remove the IPv6 address, use the no ipv6 address {ipv6-address prefix-length} command.
Parameters
ipv6-address prex-
length
Enter the IPv6 address in the x:x:x:x::x format then the prex length in the /x format. The
range is from /0 to /128.
NOTE: The :: notation species successive hexadecimal elds of zeros.
Defaults none
