VC FW update considerations

The support for IPv6, introduced in VC 4.10, requires the minimum requirements listed in "Minimum requirements to support IPv6 (on page 306)" to be met. VCSU 1.9.0 or later is required to upgrade VC IPv6 configurations.

VC maintains IP address configuration status as shown in the following table.

IP address	Details
configurations

IPv4 only	OA and VCs are configured with IPv4-only addresses. This is the default configuration.

IPv6 only	OA and VCs are configured with IPv6-only addresses. Avoid deploying an IPv6-only
	configuration until the availability of IPv6-only support for the iLOs.
IPv4-IPv6 (dual)	OA and VCs are configured with IPv4 and IPv6 addresses.

VC downgrades to versions older than 4.10

•Dual configuration

If VC has IPv4 and IPv6 (dual) address configurations, then you can immediately downgrade VC. For more information, see the VCSU rollback feature. VC will be in an IPv4-only address configuration.

•IPv4 only

If VC has IPv4-only address configurations, then you can immediately downgrade VC. VC will be in an IPv4-only address configuration.

•IPv6 onlyo Not supported

o VCSU downgrade option: If VC has IPv6-only address configurations, then you cannot downgrade. You must configure the VC with IPv4 addresses to downgrade to IPv4-only.

OA downgrades from OA 4.01

When downgrading from OA 4.01, all management IPv6 addresses in VC are removed. The configured IPv6 address on VC features such as snmp-trap, log-target, snmp-access, LDAP, RADIUS, and TACACS remain configured but are not functional unless the OA is upgraded back to OA 4.01 and IPv6 is enabled.

If a VC domain exists, IPv6 must be disabled prior to a downgrade.

Multi-enclosure considerations

•All enclosures in a VC ME configuration must have the same IP configuration. All must be IPv4, Dual Mode, or IPv6; a mixture is not supported.

•When importing an enclosure in a multi-enclosure domain, the enclosure IP configuration must be consistent with the primary enclosure.

Limitations

VC 4.10 support for IPv6 does not include the following:
