we have 2 ACS4.0 box, internal replication is happening between ACS1(prim) to ACS2(sec) but not ACS2 to ACS1 why?

Also I need 1 suggesion, whether we can connect 2 ACS boxes through cross cable for sync.

At present it is connected with 2 diff cores(ACS1 to core 1 & ACS2 to core2) and cores are interconnected.

What is the normal practice.

Its the design of the product. Its only designed for a Master-Slave relationship or Active-Passive for another term.

Only one box can be the authorative source for information. With multiple NICs you can do the replication over a cross over, but the documentation suggests that you disable all other NICs but the one you use for authentication as there are problems assicated with multihomed servers and the application.

Hi Naga,

The purpose of Replication in ACS is for the Primary Server to overwrite the secondary server's settings that you have chosen.

This is by design Replication is meant to be one way and not bi-directional.

The Cisco Secure ACS Solution Engine supports the operation of only one Ethernet connector at a time. Concurrent operation of both Ethernet connectors is not supported."

To get redundancy with any ACS - you need replication setup with TWO ACS, it is not

possible to setup a NIC failover in the same chasis.
