3.5.10.6 Redundancy Settings PRP and HSR < Conditional>
Supported by AFS66x. The PRP and HSR networks are always connected to AFS66x via ports
1/1 and 1/2, marked as port 1A and port 2B. Both ports support fiber optic connection (SFP
slot) or twisted-pair connection (RJ-45 socket). PRP function replaces interfaces 1/1 and 1/2
with interface prp/1 and HSR function replaces interfaces 1/1 and 1/2 with interface hsr/1,
that is why it is recommended to initialize configuration process of the Ethernet switch with
redundancy settings if it is applicable.

Configuration / VLAN Unaware mode = disabled (another name for the VLAN 0 transparent
mode). When VLAN Unaware mode is enabled, the device transmits data packets to all
learned ports without evaluating or changing the VLAN tagging in the data packet. The prior-
ity information remains unchanged.
