PBTS(Policy based tunnel selection) Feature Troubleshooting Guide

Policy Based Tunnel Selection feature, as the name indicates, is made up of two parts - one policy definition (or classification),  and, Tunnel configuration. Hence, it will be much easier to troubleshoot any problems with this issue, if these two parts are analyzed individually.

Troubleshooting CLASSIFICATION part of PBTS

PBTS feature is implemented using PBR (Policy Based Routing) infrastructure/framework, and as such the keyword 'pbr' is used in all CLI commands.  (Note that same set of commands are used for other features implemented using PBR infrastructure.  HTTP Redirect feature is one such example). (The term PBR and PBTS are used inter-changeably in this document, but they refer to the PBTS feature).

Enabling and collecting debug logs for PBR Classification

Before discussing the steps to perform basic validation/troubleshooting, it is important to describe the procedure to collect debug logs for PBTS.  The following commands are used to turn on the PBR debugs.

#debug pbr all

#debug policymgr all

#debug pbr-pal all location <line-card-location>

 

Note that, just like any other IOS-XR feature, the debugs are disabled by default. This means that the following  steps need to be executed to collect debug information.

1) Remove the PBR service policy from the ingress interface (if it is already applied) via 'no service-policy type pbr input <policy-name>'  command.

2) Clear left over logs via 'clear log' command

3) Enable the debug, via above described debug commands

4) Apply the PBR service policy via 'service-policy type pbr input <policy-name>' command

5) Collect logs via 'sh log' command

6) Disable debugs via 'undebug all' command

 

Steps to troubleshoot PBR Classification

1)    Make sure that PBR policy is configured and applied to the ingress interface properly via the following commands :

 

RP/0/RSP0/CPU0:ios#sh running-config interface gigabitEthernet 0/3/0/0    

Fri Feb  8 20:59:31.325 UTC

interface GigabitEthernet0/3/0/0

 service-policy type pbr input prec

 ipv4 address 80.80.80.1 255.255.255.0

!

RP/0/RSP0/CPU0:ios#sh running-config policy-map type pbr prec        

Fri Feb  8 20:59:35.431 UTC

policy-map type pbr prec

 class type traffic pre-2

  set forward-class 2

!

 class type traffic class-default

 !

 end-policy-map

RP/0/RSP0/CPU0:ios#sh running-config class-map type traffic pre-2    

Fri Feb  8 20:59:39.143 UTC

class-map type traffic match-any pre-2

 match access-group ipv4 pre-1

 end-class-map

!

 

If there is a failure during configuration, enable the debugs and collect logs (Refer Enabling and collecting debug logs section).

2)    If the configuration is present, but the classification still doesn't work,  check if the packets are classified to the correct class, via the following commands :

 

RP/0/RSP0/CPU0:ios#sh policy-map type pbr interface gigabitEthernet 0/3/0/0

Fri Feb  8 21:31:55.254 UTC

GigabitEthernet0/3/0/0 input: prec

Policy Name: prec

Class pre-2

  Classification statistics          (packets/bytes) (May be 10secs old)

    Matched             :                   0/0                   

  Transmitted statistics             (packets/bytes) (May be 10secs old)

    Total Transmitted   :                   0/0                   

Class class-default

  Classification statistics          (packets/bytes) (May be 10secs old)

    Matched             :                   0/0      

 

RP/0/RSP0/CPU0:ios#sh pbr-pal interface gigabitEthernet 0/3/0/0 location 0/3/cpu0

Fri Feb  8 21:35:53.141 UTC

Interface:GigabitEthernet0/3/0/0  Underlying interface:Unknown Port:0

--------------------------------------------------

Class:7 ACL: fwd_class_id:0

Stats Ptr: 0x5302bf Pkts: 0, Bytes: 0

 

- If the traffic is matched to incorrect class, check if the traffic pattern/keys match with the policy configured on the interface, and the keys are supported in 4.3.1 release. If they match, check if the PBR/QOS feature ordering is set correctly using the following command :

 

RP/0/RSP0/CPU0:ios#sh running-config | incl apply

Fri Mar 29 18:28:22.773 UTC

Building configuration...

service-policy apply-order qos pbr

RP/0/RSP0/CPU0:ios#

 

RP/0/RSP0/CPU0:ios#sh controllers np portmap all | incl GigE0/3/0/0                

Fri Mar 29 18:32:44.582 UTC

16                GigE0/3/0/0                     63 (unmapped)

RP/0/RSP0/CPU0:ios#sh controllers np configSram 16 np0 location 0/3/cpu0 | incl PBR

Fri Mar 29 18:32:46.541 UTC

  Qos before PBR                   0x1

RP/0/RSP0/CPU0:ios#

 

Note that, by default, PBR feature is processed before QOS. Make sure the configuration matches what the customer wants to do.  If still packets are classified to incorrect class , then  proceed to next step.

 

- If the traffic is not matched to any traffic, check and make sure the ingress interface is the correct one, and the PBTS feature itself is supported in 4.3.1 release. If the interface is correct/supported one, then, proceed to next step.

 

3)    Collect the hardware state of the PBR feature using the following commands, while the system is in failed state.

RP/0/RSP0/CPU0:ios#sh uidb data location 0/3/cpu0 gigabitEthernet 0/3/0/0 ingress | incl PBR

Fri Mar 29 18:54:22.145 UTC

In addition, to the above commands, it will be best to capture the debug logs, by following the procedure listed in the Enabling and collecting Debug Logs Section.

Troubleshooting Tunnel part of PBTS

Most of the troubleshooting techniques used for FIB/MPLS/MPLS-TE in IOS-XR are applicable for PBTS as well, as PBTS just enhances the basic forwarding, through the use of 'forward-class' element.  This section assumes that the user has already confirmed the working of PBR classification and confirmed that the correct forward-class is being derived for the given traffic. (If this is not the case, pl. refer to 'TROUBLESHOOTING POLICY-DEFINITION PART OF PBTS section).

Collecting Debug Logs

FIB module makes use of tracing infrastructure, so by default, tracing is enabled. The following commands output the captured tracing information.

sh cef ipv4 platform trace common both all loca <LC>

sh cef mpls platform trace common both all loc <LC>

show cef platform trace all all location <LC>

 

Steps to troubleshoot PBTS Tunnel configuration

1) Make sure the MPLS-TE tunnels are configured and they are UP. Pl. refer to MPLS-TE document for detailed set of commands, but the following commands are applicable/relevant to PBTS feature :

Note that only requirements for PBTS is to configure the 'forward-class' interface command for each MPLS-TE that must be part of PBTS feature. If the above commands confirm that MPLS-TEs are properly configured and UP,  and, if the PBTS feature is still not functional, then, proceed to the next step.

 

2) Collect the hardware state of the FIB entry using the following command :

Xander,

Great article. I wonder these Troubleshooting commands are still relevant on version 5.3.3.

hi jm,

they sure are :) yup can still use them,

cheers!

Xander,

I wonder whether PBTS is now supported on satellite interfaces on 5.3.3 code?

The configuration is accepted as below, however the show policy output says not installed. the router is running 5.3.3 with sp3, and satellite 9000v with 533.101

interface GigabitEthernet100/0/0/2
service-policy type pbr input POLICY_INET_TRAFFIC

RP/0/RSP0/CPU0:CIPC4-Lab#sh policy-map type pbr int gigabitEthernet 100/0/0/2
GigabitEthernet100/0/0/2 direction input: Service Policy not installed

Thanks,

I believe not yet. Is there a business to support it, let us know.

is using PBR/policy based routing an option?

with that we can define classification criteria provided by PBR and set the next hop to be the remote tunnel endpoint and force tunnel selection based on that?

cheers!!

Thanks xander for your suggestion. But that will be a complete routing redesign and additional set of tunnel creation which we would prefer to avoid.

Could you advise where on road map now for PBTS to be available on satellite interfaces?

Thanks,

hi mei,

the way we implemented PBTS is by means of PBR selection, this will work on satellite interfaces also since that is driven out of the a9k host.

is there a func missing in PBR that you need the selection for? if so, yeah as per dinesh, let us know what the func is and what the use case is so we can pursue it (possibly)...

Hi xander,

TAC Engineer [Rahul Kukreja] just informed me this other command "show policy-map type pbr interface all" to use, and it shows policy-map pbr IS installed on satellite interface, further we verified the feature is functioning on satellite interfaces. 

As long as the function is there, we can live with and get used to this other verification command.

Cheers.

Mei
