ACS 5.4 multiple network interfaces support

In ACS 5.4 release note, it says:

Multiple network interface connector support

ACS 5.4 supports up to four network interfaces: Ethernet 0, Ethernet 1, Ethernet 2, and Ethernet 3. ACS management functions use only the Ethernet 0 interface, but AAA protocols use all configured network interfaces. You must connect the ACS nodes in the distributed deployment only to the Ethernet 0 interface. Therefore, the syslog messages are sent and received at the log collector's Ethernet 0 interface. Data forwarding from one interface to another interface is prohibited to prevent potential security issues. The external identity stores are supported only on the Ethernet 0 interface. In ACS 5.4, multiple network interface connectors are also supported for proxies.

But in the CSACS 1121 Series Appliance Rear View section, it still says on Ethernet 0 is usable. All other interfaces are blocked.

I am confused. Can anyone clarify for me if we can use multiple network interface in ACS 5.4? What about management interface?

Thanks!

Hi,

Looks like the installation guide hasnt caught up to the latest release notes. You should be ok to add the additional interfaces.

Thanks,

Has anyone configured multiple interfaces and got it working properly?

We configured 2 interfaces in past within testing enviornment and it worked. ACS 5.4 supports multiple network interfaces on the UCS platform, on a virtual machine and on the legacy ACS 5.x IBM/CAM hardware. The ACS management functions use the interface eth0 only and the AAA protocols use all available network interfaces.
