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 IP Addresses and Services Command Reference for Cisco ASR 9000 Series Routers.

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.


Note

If two different ACLs with same ACEs are applied to an LPTS Policer, only the first ACL applied takes effect. When the first ACL is removed, the second ACL does not take effect on the LPTS Policer. If you want the second ACL to take effect on the LPTS Policer, reconfigure it on the LPTS Policer.

IP TOS Precedence

By default, router allows all packets into the network. The IP table of service (TOS) precedence feature allows you to classify packets by IP precedence value. The IP precedence value can be configured for every flow. Once configured for a flow type, only packets that match the defined IP precedence value are allowed, and others are rejected.

The precedence value can either be a number or name. This table lists configurable precedence values:
Table 1. Precedence Values
Precedence Number Precedence Name Description

0

routine

Matches packets with routine precedence.

1

priority

Matches packets with priority precedence.

2

immediate

Matches packets with immediate precedence.

3

flash

Matches packets with flash precedence.

4

flash-override

Matches packets with flash override precedence.

5

critical

Matches packets with critical precedence.

6

internet

Matches packets with internetwork control precedence.

7

network

Matches packets with network control precedence.

ACL Based Policer

ACL based policer is a session based policer that provides secure network access based on session.


Note

  • The ACL based policer feature is supported only on ASR 9000 Enhanced Ethernet Line Cards, ASR 9000 3rd Generation Line Cards, and ASR 9000 4th Generation Line Cards.

  • SNMP is not supported on ASR 9000 4th Generation Line Cards. Therefore, the ACL entries configured based on LPTS are not displayed if the ACLs are configured on ASR 9000 4th Generation Line Cards.

  • When multiple ACLs are configured for an LPTS policier, only the first ACL details are displayed in the LPTS statistics command output.

Benefits

These are the benefits of ACL based policer:

  • Rate limit incoming packets based on session.

  • Modify policer rate depending on traffic load.

  • Block entire traffic based on a specific session without impacting other sessions with same flow.

Configuring LPTS Policers

This task allows you to configure the LPTS policers.

  2. lpts pifib hardware police [location node-id]
  3. flow flow_type {rate rate}
  4. commit
  5. show lpts pifib hardware police [location {all | node_id}]

DETAILED STEPS

  Command or Action Purpose

Step 1

configure

Step 2

lpts pifib hardware police [location node-id]

Example:


RP/0/RSP0/CPU0:router(config)# lpts pifib hardware police location 0/2/CPU0
RP/0/RSP0/CPU0:router(config-pifib-policer-per-node)#


RP/0/RSP0/CPU0:router(config)# lpts pifib hardware police
RP/0/RSP0/CPU0:router(config-pifib-policer-global)#

Configures the ingress policers and enters pifib policer global configuration mode or pifib policer per node configuration mode.

The example shows pifib policer per node configuration mode and global.

Step 3

flow flow_type {rate rate}

Example:


RP/0/RSP0/CPU0:router(config-pifib-policer-per-node)# flow ospf unicast default rate 20000

Configures the policer for the LPTS flow type. The example shows how to configure the policer for the ospf flow type.

  • Use the flow_type argument to select the applicable flow type. For information about the flow types, see IP Addresses and Services Command Reference for Cisco ASR 9000 Series Routers.

  • Use the rate keyword to specify the rate in packets per seconds (PPS). The range is from 0 to 4294967295.

    Note

     

    LPTS policy for ntp-default flow type, supports a flow rate of 100 pps on Cisco ASR 9000 Series Router.

    Starting with Cisco IOS XR Release 6.1.3, LPTS policy for ntp-default flow type, supports a flow rate higher than 100 pps on Cisco ASR 9000 Series Router.

    Based on the number of NTP client scale requirement, you can increase the flow rate value to allow higher packets per second (PPS). For example, 

    lpts pifib hardware police location 0/0/CPU0
 flow ntp default rate 1000
 flow ntp known rate 1000

Step 4

commit

Step 5

show lpts pifib hardware police [location {all | node_id}]

RP/0/RSP0/CPU0:router(config-pifib-policer-per-node)# flow telnet default
or
RP/0/RSP0/CPU0:router(config-pifib-policer-global)# flow telnet default

Configures the policer for the LPTS flow type. The example shows how to configure the policer for the telnet flow type per node or global mode (all locations).

  • Use the flow_type argument to select the applicable flow type. For information about the flow types, see IP Addresses and Services Command Reference for Cisco ASR 9000 Series Routers.

Step 4

precedence {number | name}

Example:

RP/0/RSP0/CPU0:router(config-pifib-policer-per-node)# precedence 5 6 7

The example shows how to configure IP TOS precedence 5, 6, and 7 per node or global mode.

Step 5

commit

Step 6

show lpts pifib hardware police [location {all | node_id}]

Example:


RP/0/RSP0/CPU0:router# show lpts pifib hardware police location 0/2/cpu0

Displays the policer configuration value set.

  • (Optional) Use the location keyword to display policer value for the designated node. The node-id argument is entered in the rack/slot/module notation.

  • Use the all keyword to specify all locations.

Mapping the LPTS Policer with an ACL

This task allows you to map the LPTS policer with an ACL.


Note

  1. LPTS to ACL map supports only the following values:

    • Source Destination Address

    • Source and destination port

    • Protocol number

    • Object Groups (both network and port groups)

  2. When multiple ACLs are configured for an LPTS policier, only the first ACL details are displayed in the LPTS statistics command output.

  3. When you are applying an ACL on an LPTS entry, LPTS entry filters and ACL should be defined in the same order. So, if you want to limit incoming traffic from the host 10.10.10.10 to any router ip address you need to define LPTS ACL as permit ip from any to 10.10.10.10.

    For example, assume that 10.10.10.10 is the remote address from which traffic should be filtered. The LPTS and ACL should be defined as shown in the following table.

    LPTS (local address, port, remote address, port)

    ACL

    (any,23, 10.10.10.10,65248)

    ipv4 access-list lpts 10 permit ipv4 any host 10.10.10.10

  4. You can configure a maximum of 50 ACLs per LPTS policer.

  5. You can use the following commands to view the LPTS ACL Policer information:

    • show lpts pifib hardware entry acl name statistics location

    • show lpts pifib hardware police location

    • show lpts pifib hardware entry statistics location


    Note

    The A9K-20HG-FLEX-SE, A9K-20HG-FLEX-TR, A99-32X100GE-X-SE, A99-32X100GE-X-TR, A9K-8HG-FLEX-SE, and A9K-8HG-FLEX-TR line cards do not include LPTS ACL Policer information in show lpts pifib hardware police location and show lpts pifib hardware entry statistics location commands.

SUMMARY STEPS

  1. configure
  2. lpts pifib hardware police acl acl-name1 rate 100 vrf vrf1
  3. commit

DETAILED STEPS

  Command or Action Purpose

Step 1

configure

Step 2

lpts pifib hardware police acl acl-name1 rate 100 vrf vrf1

Example:


RP/0/RSP0/CPU0:router(config)# lpts pifib hardware police acl acl-name1 rate 100 vrf vrf1

Maps the LPTS policer with the ACL by name acl-name1.

Step 3

commit

NP Based Policer

Network processor (NP) based policers in LPTS allow rate limit packets based on a specific NP with specific rate.

Benefits of NP based policer

  • Rate limit incoming packets based on a specific NP with specific rate.

  • Provides secure network access based on the context of a user or a device.

    For example, if a user does not require specific traffic on a particular NP, then the rate limit can be set to 0.

  • Modify policer rate depending on traffic load.

  • Full utilization of traffic through each NP depending on traffic.

  • Stop or block complete traffic based on a specific NP without impacting other NPs with same flow.

Configuring ACL, NP, LPTS Local, LPTS Global, and LPTS Static Policers: Example

This topic contains sample configurations and output examples of ACL, NP based, LPTS local, LPTS global, and LPTS static policers.

ACL Based Policer

The following is a sample ACL based policer configuration. In this example, the ACL is applied to a BGP session. 

RP/0/RSP1/CPU0:router(config)# ipv4 access-list lpts_acl_1
RP/0/RSP1/CPU0:router(config-ipv4-acl)# 10 permit tcp any host 200.0.0.1
RP/0/RSP1/CPU0:router(config-ipv4-acl)# 20 deny ipv4 any any

Configuring LPTS policers with IP TOS Precedence: Example

  • The following example shows how to configure IP TOS to telnet default flow and allow packets with precedence 3 or 4 at node 0/0/CPU0: 

    configure
lpts pifib hardware police location 0/0/CPU0 
flow telnet default 
precedence 3 4

  • The following example shows how to configure IP TOS to telnet known flow to only allow packets with precedence 5 or 6 or 7 at all nodes 

    configure
lpts pifib hardware police 
flow telnet known 
precedence 5 6 7

  • The following example shows how to configure IP TOS to telnet known flow to only allow packets with routine and network precedence at all nodes 

    configure
lpts pifib hardware police 
flow telnet known 
precedence routine network
