Troubleshooting
Problem
The Load Balancer's MAC and encapsulated MAC forwarding methods require aliasing the cluster address on loopback interface of the back-end servers. The loopback interface is a special interface that is used for communication within the server and is not used to transmit data on the network. The default installation of Linux™ advertises all addresses, even locally scoped addresses on interfaces that do not transmit data. If these settings are not changed, client traffic is routed directly to the server, by-passing the Load Balancer.
MAC forwarding requires extra configuration on Linux servers.
Symptom
- Cluster traffic is routed to a single back-end server.
- The Load Balancer packet-forwarded statistics do not increase.
- Traffic not routed to all available servers.
