5.2 PRODUCT SETUP CHAPTER 5: SETPOINTS
frame received and discard the duplicate through a link redundancy entity (LRE) or similar service that operates
below layer 2. Aside from LRE, PRP uses conventional Ethernet hardware but both ports must know they are in
PRP. Both ports of PRP devices operate with the same Internet Protocol (IP) addresses for traffic that uses IP
Management protocols such as Address Resolution Protocol (ARP).
· HSR (High-availability Seamless Redundancy): ports A and B use the same MAC (physical device) address
and combine information at the link layer. It is intended to work in a ring topology. In this mode of operation port A
is connected to other device´s port B, and port B is connected to other device´s port A provided that ring topology
is respected. The receiving devices process the first frame received and discard the duplicate through a link
redundancy entity (LRE) or similar service that operates below layer 2. Aside from LRE, HSR uses conventional
Ethernet hardware but both ports must know they are in HSR. Both ports of HSR devices operate with the same
Internet Protocol (IP) addresses for traffic that uses IP Management protocols such as Address Resolution
Protocol (ARP).
· RSTP (Rapid Spanning Tree Protocol): ports A and B use the same MAC (physical device) address and can
operate with different network topologies. The device operates only with one IP address through these 2 ports
· DAISY CHAIN: ports A and B use the same MAC (physical device) address and operate by chaining one device
with the next one. Note that it is important not to create a loop in this topology. Both ends of the chain can be
connected to different networks. The device operates only with one IP address through these 2 ports.
NOTE 3: When LLA/PRP/HSR or PRR mode is selected, MAC addresses assigned to port A and B are the same
between them and a consecutive value of MAC address assigned to port E.
E.g (MAC_portE: 00AFF40A24DA, MAC_portA:00AFF40A24DB, MAC_portB: 00AFF40A24DB)
NOTA 4: When LLA/PRP/HSP/RSTP or DAISY CHAIN mode is selected, the IP configured at
Product Setup > Communication Settings > Network (Ethernet) > Network (Ethernet) A is the one used by
both ports (A and B) to communicate in these modes.
LLA PRIORITY: If this setting is set to enabled, the port A has the priority. If PORTA’s LLA detects a problem with the link,
communications is switched to Port B. Port B is, in effect, acting as a redundant or backup link to the network for port A.
LLA TIMEOUT: This setting is active only when the LLA PRIORITY is set to ENABLED. When the link on primary port is
detected again after it fails, there is LLA TIMEOUT (ms) monitoring time for the health of the network. During this time, the
secondary port remains active. If primary network is healthy for more than LLA TIMEOUT value, the switch over to primary
port is automatic.
RSTP BRIDGE PRIORITY: Specifies the switch (bridge) priority value. This value is used along with the switch MAC
address to determine which switch in the network is the root device. Lower values mean higher priority. The value ranges
from 0 to 65535, with a default of 32768.
RSTP PORTA PRIORITY: This is to determine which ports are used for forwarding. Lower the number means higher
priority. Value ranges from 0 to 255. Default is 128 .
RSTP PORTA PATHCOST: This is the assigned port cost value used for the switch to determine the forwarding points.
Values range from 1 to 2000000. The lower the value, the lower the cost and hence the preferred route.
RSTP PORTB PRIORITY: This is to determine which ports are used for forwarding. Lower the number means higher
priority. Value ranges from 0 to 255. Default is 128 .
RSTP PORTB PATHCOST: This is the assigned port cost value used for the switch to determine the forwarding points.
Values range from 1 to 2000000. The lower the value, the lower the cost and hence the preferred route.
