Achieving Zero Recovery Time: PRP vs. HSR

[@stringsandhamers]

Why a non-hsr device must use a redbox? Why it cant be connected to a hrs switch (like the others non hsr devices)?

Hi @stringsandhamers, thanks for reaching out. Standard Ethernet devices can’t be connected directly to HSR ring because HSR modifies the frame and it can’t be processed correctly by a non-HSR node. To connect Singly Attached Nodes to HSR ring a Rebox or HSR switch should be used. HSR switch is essentially a combination of a switch and Redbox in a single unit, so from IEC standard point of view HSR switch is a multiport Rebox. The terms Redbox and HSR switch sometimes could be used interchangeably.

In your example, you are using PT-G7728 for PRP Ring A, My question, can we use PT-7728 instead PT-G7728. how is the PTP complience on those 2 type switch. are both type are PTP complience switch.?. Thanks in advance for your respond

Hi @setiawanadi4388, thanks for reaching out. Only PT-7728-PTP models within the PT-7728 range support PRP/HSR when equipped with PM-7200-4GTX-PHR-PTP or PM-7200-4GSFP-PHR-PTP modules, and both PT-7728-PTP and PT-G7728 support IEEE 1588 hardware-based PTP.
