Parameter
PTP Filter
ProSoft Technology, Inc.
Description
Check this box to enable the PTP Filter feature. The Precision Time Protocol
(PTP) is used in industrial networks to synchronize time between devices.
Given the protocol uses multicast addressing, a PTP packet sent by one device
is sent over every wireless link in that network. PTP is only needed amongst a
set of local Ethernet connected units. The injection of PTP packets arriving over
a wireless link (connecting this local network to the main network) may cause
large errors in time synchronization.
To prevent leaking of PTP packets, the following control allows the RLX2-IHx
Series to filter any PTP packets received on its Ethernet port. When this
capability is desired, this control should be enabled on all Masters and
Repeaters in the network
