Configure STA to Support Dual TCP/IP or RE (SL3000 and SL8500 Only)
STA is capable of maintaining uninterrupted connections with only up to two library IP addresses at a time. Therefore, on a given library, you can configure STA to support either Dual TCP/IP or Redundant Electronics (RE), but not both.
For libraries with both features, Oracle recommends that you configure STA to support Redundant Electronics, as this feature is more critical to maintaining continuous library operations.
If a library has both Redundant Electronics and Dual TCP/IP, the STA server's subnet must be different from the subnet of the library port not configured for STA (see Configure SNMP on the STA Server). Otherwise, the library may try to send data through those ports (unknown to STA), and the data will be rejected by STA. Make sure your default gateway is the 2B interface.
See the product's Library Guide for details about Dual TCP/IP and RE.
