with IPLC
For OSC communications across the amplifier chain, the PTX3000 integrated photonic
line system uses an anchor IPLC module, which communicates directly with each optical
ILA. Because IPLC modules are standalone appliances in the chassis, they have no host
path connectivity to the routing engine or switch fabric and thus have no connectivity to
other FPC interfaces, as such, all OSC communications go through the anchor IPLC. You
can designate only one IPLC in the line system as the anchor of the amplifier chain.
For OSC communications and identification purposes, you assign each IPLC module and
each optical ILA a unique, private IP address. OSC communications use an internal private
LAN and IPLC modules and optical ILAs must be on the same, private IP subnet. OSC
management IP addresses are not advertised by the PTX3000 Series router and are not
auto-discoverable. You can further identify optical ILAs by specifying a unique
identification number. IPLC modules are also identified by their MAC address.
NOTE: You can configure only one IPLC module as the anchor IPLC of the
PTX3000 integrated photonic line system and you must specify that the
remote PTX3000 router as not an anchor IPLC.
NOTE: For OSC communications, all optical ILAs and IPLC modules must be
on the same, private IP subnet as the anchor IPLC.

SNMP Management Overview and Configuration

If you are using an SNMP network management system (NMS) to manage the optical
ILAs in the amplifier chain, there is no direct communication between the optical ILAs in
the amplifier chain and the SNMP NMS. All communication to and from the SNMP NMS
and optical ILAs in the chain is handled by the anchor IPLC module. The IPLC modules
relays the command to the specified optical ILA. Each command from the NMS must
include a community string indicating the unique identification number of the optical ILA
in the amplifier chain. SNMP traps are propagated from each optical ILA to the anchor
IPLC and out to the SNMP NMS.
