ACSLS High Availability Dual TCP/IP Example

The following example is an ACSLS High Availability (HA) environment that requires
dual TCP/IP. The purpose of the HA environment is to have two ACSLS servers, one
active and one standby. In this configuration, two ACSLS servers connect six network
interfaces (three on each server) to two separate subnets. A third subnet connects the
two ACSLS servers through a public network.
For more information on ACSLS HA and dual TCP/IP, see the ACSLS Administrator's
Guide.

Routing

You should separate the SL3000 network interfaces over two different subnets when
using ACSLS HA. The two different ACSLS servers use different network interfaces;
therefore, you should add custom route entries to both ACSLS HA servers. Add the IP
addresses for both servers to the SL3000 configuration.

Routing Tables

Add custom entries to the routing tables on the ACSLS server; however, any
customized routing table entries will be lost after a restart of the ACSLS server. To
maintain custom routing table entries, create scripts to add custom routes. Place the
scripts in the rc directory structure for automatic execution at boot time.
For more information, refer to the ACSLS Administrator's Guide.
