Can I build redundancy across two ports for Fabric and Precision Time?
Can I build redundancy across two ports such that Equinix Fabric Port A goes to Timing Master 1, and Equinix Fabric Port B goes to Timing Master 2?
No, a single connection always goes to both master time servers:
When you select the Fabric Port redundancy option, your configuration will have redundant Fabric Virtual connections. Each connection connects to same two timing masters.
