Packet Bridging Requirements
For packet bridging to work properly, it is important to have an attached router on the Ethernet side that provides advanced functions. Specifically, the router should support:
VLAN tagging for particular IP addresses/subnets—To support the routing function in the CTP system.
Per-VLAN bandwidth shaping—To avoid overloading the CTP bridged Ethernet-to-serial link with too much bandwidth. Otherwise, packets will eventually be dropped because the serial packet driver to the line will not be able to accept the packet.
Per-VLAN pps shaping—To avoid overloading the CTP system with too high of a packet rate.
