Chapter 12 Replication and High Availability

Replication Status

Replication Status

At any moment in time you can check the replication status of the Cisco NAC Guest Servers. This is useful to make sure replication is happening as you want it to.

Step 1 From the administration interface select Authentication > Replication Settings from the left hand menu (Figure 12-3).

Figure 12-3 Replication Status

At the bottom of the page is the Replication Status. You can check the status of replication and how many changes need to be replicated between each device.

Recovering from Failures

Network Connectivity

When the network connectivity between two Cisco NAC Guest Servers fails the Cisco NAC Guest Servers will store up to 1GB of changes. When connectivity is restored if the amount of changes is less than 1GB they will synchronize with each other. If more than 1GB of changes are stored the Cisco NAC Guest Server will stop the replication process and you will need to setup replication again.
