Support for Sysplex-Wide Security Associations (SWSA) for IPv6
DVIPAs is provided in z/OS® V2R1
Communications Server or
later releases.
- Encapsulated IPv6 traffic can be distributed to a target stack
that is at the V2R1 or later
release level.
- When an IPv6 DVIPA is taken over, SAs for that DVIPA can be reestablished
by a backup stack that is at the V2R1 or later
release level. A stack that is at release level V1R13 or earlier does
not retrieve SA data associated with the IPv6 DVIPA from the coupling
facility; the SAs are not renegotiated and the SA data remains in
the coupling facility. If the original owning stack (V2R1 or later)
regains ownership of the IPv6 DVIPA, SA data remaining in the coupling
facility is used to attempt to reestablish the SAs. Do not use a stack
that is at the V1R13 or earlier release level as a backup for an IPv6
DVIPA when there are SAs for the DVIPA.
