System Overview
Configuration Tips
This section describes common issues and how to avoid them.
Ethernet Port configuration
•
The Ethernet ports of a PTP 850E are not enabled by default in a new unit. You must manually enable the
Ethernet port or ports in order for the unit to process Ethernet traffic. See
Enabling the Interfaces (Interface
Manager)
• For RJ-45 ports, it is recommended to enable Auto-Negotiation for both the local port and its peer in order to
obtain optimal performance.
•
For SFP ports, it is recommended to disable Auto-Negotiation.
• For instructions, see Configuring Ethernet Interfaces.
SyncE Interface Configuration
•
When configuring a Sync source or outgoing clock on an Ethernet interface, the Media Type of the interface
must be RJ-45 or SFP, not Auto-Type. See
Synchronization.
In-Band Management
• In order to use in-band management with an external switch, it must be supported on the external switch.
•
When configuring in-band management, be sure to tag the management traffic to avoid overflow of the CPU.
• For instructions on configuring in-band management on the PTP 850E, see Configuring in-Band Management.
Link Aggregation
• If you are configuring LAG with an external switch, the switch must support LAG. For instructions on
configuring LAG, see
Configuring Link Aggregation (LAG) and LACP.
Software Upgrade
•
When upgrading software via HTTP, make sure the software package is not unzipped. For instructions, see
Upgrading the Software.
Configuration Management and Backup Restoration
• Configuration files can only be copied to the same PTP 850 hardware type with the same part number as the
unit from which they were originally saved. For example, a PTP 850E configuration file can only be restored to
a PTP 850E with the same part number as the unit from which it was saved.
