Configuring TACACS+
RUGGEDCOM ROS can be configured to use two TACACS+ servers: a primary server and a backup server. If the
primary server is unavailable, the device will automatically attempt to connect with the backup server.
To configure access to either the primary or backup TACACS+ servers, do the following:
1. Navigate to Administration» Configure Security Server» Configure TacPlus Server» Configure TACACS
Plus Server . The TACACS Plus Server table appears.
