Open/R on the PoP interface port
PoP interface port must be configured to run the Open/R protocol. To enable this option, select Multi-
PoP/ Relay port Interface.

Multi-PoP/Relay Port Interface
MTU of upstream switch ports
PoP ports use a 2000 MTU size. So, all the switch ports must be at least 2000 MTU size. Even if the user
traffic is limited to 1500 sized packets, switch ports should allow the higher MTU size. The following
packets exchanged between the PoPs that can be of higher size:
l
Open/R packets,
l
L2GRE packets (in Layer 2 mode), and
l
Software download packets.
Prefix allocation
It is recommended to select the Deterministic Prefix Allocation option for multi-PoP deployments.

Layer 2 control protocols
60 GHz cnWave identifies layer 2 control protocols (L2CPs) from the Ethernet destination address or
Ethertype of bridged frames. The QoS classification can be separately configured for these protocols.
Ethernet port allocation
The user must decide how the three ODU Ethernet ports are allocated to the data service, management
service and Local Management Service based on the following rules:
l
Map the Data Service to at least one of the available wired Ethernet ports.
l
Map the Management Service to In-Band, or any combination of the remaining unused Ethernet
ports. If the Management Service is mapped to In-Band, it shares all the ports selected for the Data
Service. The Management Service can be disabled by mapping to None.
