Figure 15-2 URL-Based Server Load Balancing
Configuring URL-Based Server Load Balancing
To configure URL-based SLB, perform the following steps:
1. Before you can configure URL-based load balancing, ensure that the switch has already
been configured for basic SLB with the following tasks:
N OTE – When URL-based SLB is used in an active/active redundant setup, use a proxy IP
address instead of Direct Access Mode (DAM) to enable the URL parsing feature.
n
Assign an IP address to each of the real servers in the server pool.
n
Define an IP interface on the switch.
n
Define each real server.
n
Define a real server group and set up health checks for the group.
n
Define a virtual server on virtual port 80 (HTTP), and assign the real server group to service it.
n
Enable SLB on the switch.
n
Enable client processing on the port connected to the clients.
For information on how to configure your network for SLB, see “Server Load Balancing” on
page 117 .
