Setting Up Logical Ports
The OM 1000 supports up to 16 logical ports, designated as 1 through 16.
To set up a logical port:
Select the logical port number to configure.
Select the physical interface associated with the logical port.
Select the port type: input or output. For input ports, a PID map must also be defined (refer
to the Setting PID Maps section for details on setting up an input port PID map).
For Ethernet input ports, a unique source UDP port must be defined. Each Ethernet UDP
port defined will receive singlecast or broadcast data. If the UDP port is to receive multicast
data, then up to five multicast IP host addresses can be defined for each UDP port. Refer to
the Setting Receive Multicast IP Addresses section for more details.
For Ethernet output ports, a destination IP address and port must also be defined. The IP
address can be a singlecast address, broadcast address, or a multicast address.

Setting PID Maps (Input Ports Only)
When a logical port is configured as an input, it has an associated PID map to control how the
packet multiplexer processes input datastreams received by the port. Output ports do not have
PID maps. Each PID map specifies processing for an individual input PID stream.
A PID map has 28 available slots with five entries for each slot, as shown in Table 4-9:

The first slot represents the default value. The PID table determines the routing of incoming
PIDs to destination ports 1, 2, and 3. You can designate as many as three destination ports
simultaneously.
Slot 1 is the default slot. Any PID not remapped in slots 2 through 28 uses the port routing
setup of slot 1. For slots 2 through 28, you can remap an input PID (PID-IN) as a different
output PID (PID-OUT). In the example, slot 2 is remapping PID 6 to become PID 3, with the
remapped PID 3 sent to a single destination port, logical port 1. All other PID inputs use the
default slot 1 setup. In this case, all input PIDs, other than PID 6, are sent to logical port 0 (the
bit bucket).
