Chapter: Implementing LPTS
Implementing LPTS
Local Packet Transport Services (LPTS) maintains tables describing all packet flows destined for the secure domain router (SDR), making sure that packets are delivered to their intended destinations.
For a complete description of the LPTS commands listed in this module, refer to the LPTS Commands module of Cisco IOS XR IP Addresses and Services Command Reference for the Cisco XR 12000 Series Router.

Prerequisites for Implementing LPTS
The following prerequisites are required to implement LPTS:
You must be in a user group associated with a task group that includes the proper task IDs. The command reference guides include the task IDs required for each command. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Information About Implementing LPTS
To implement LPTS features mentioned in this document you must understand the following concepts:
LPTS Overview
LPTS uses two components to accomplish this task: the port arbitrator and flow managers. The port arbitrator and flow managers are processes that maintain the tables that describe packet flows for a logical router, known as the Internal Forwarding Information Base (IFIB). The IFIB is used to route received packets to the correct Route Processor or line card for processing.
LPTS interfaces internally with all applications that receive packets from outside the router. LPTS functions without any need for customer configuration. However, LPTS show commands are provided that allow customers to monitor the activity and performance of LPTS flow managers and the port arbitrator.
LPTS Policers
In Cisco IOS XR, the control packets, which are destined to the Route Processor (RP), are policed using a set of ingress policers in the incoming line cards. These policers are programmed statically during bootup by LPTS components. The policers are applied based on the flow type of the incoming control traffic. The flow type is determined by looking at the packet headers. The policer rates for these static ingress policers are defined in a configuration file, which are programmed on the line card during bootup.
You can change the policer values based on the flow types of these set of ingress policers. You are able to configure the rate per policer per node (locally) and globally using the command-line interface (CLI); therefore, overwriting the static policer values.
Configuring LPTS Policer with IP TOS Precedence
This task allows you to configure the LPTS policers with IP table of service (TOS) precedence:
1.
configure
2.
lpts pifib
hardware police [location
node-id]
3.
flow
flow_type
4.
precedence
{number

name}
5.
commit
6.
show lpts pifib
hardware police [location {all |
node_id}]

Configuring LPTS Policers

Configuration Examples for Implementing LPTS Policers
This section provides the following configuration example:
Configuring LPTS Policers: Example
The following example shows how to configure LPTS policers:
