Centralized syslog management with structured, priority-based logging, UDP forwarding, and IPv6 support

Use centralized syslog configuration on an aggregation device to enforce uniform logging across satellite devices. Satellites forward logs over UDP to the aggregator, which collects and relays them to external syslog servers for comprehensive diagnostics. Configure structured and priority-based logging on satellites to enhance monitoring and analysis while maintaining security and compatibility, with IPv6 support.
