Figure 95 - Rewrite Cookie Mode, page 591 illustrates the rewrite cookie mode operation:
Figure 95: Rewrite Cookie Mode
Note: When Alteon rewrites the value of the cookie, the rewritten value represents the responding
server. This means that the value can be used for hashing into a real server ID or it can be the real
server IP address. The rewritten cookie value is encoded.
Configuring Cookie-Based Persistence
The following is an example procedure for configuring cookie-based persistence.
To configure cookie-based persistence
1. Before you can configure cookie-based persistence, configure Alteon for basic SLB:
— Assign an IP address to each of the real servers in the server pool.
— Define an IP interface.
— Configure each real server with its IP address, name, weight, and so on.
— Assign servers to real server groups.
— Define virtual servers and services.
For information on basic SLB configuration, see Server Load Balancing, page 165
.
2. Either enable Direct Access Mode (DAM), or disable DAM and specify proxy IP addresses on the
client ports.
— Enable DAM.
