affinity location-set


Note


Effective with Release 3.9.0, the affinity location-set command was deprecated.


To set the affinity of a placeable program (process) to or from a group of nodes, use the affinity location-set command in placement program configuration mode. To remove the affinity location set, use the no form of this command.

affinity location-set node-id { attract strength | repulse strength | default | none }

no affinity location-set node-id { attract strength | repulse strength | default | none }

Syntax Description

node-id

Specifies the node or group of nodes to which or from which to set the affinity. The node-id argument is expressed in the rack/slot/module notation. To specify multiple nodes, enter the node-id for each node. You can specify a node pair, or up to 5 nodes.

attract

Specifies a positive affinity.

repulse

Specifies a negative affinity.

strength

Positive or negative strength. The range is from 1 to 100000 points.

default

Sets the affinity location-set default value, which is equivalent to specifying an attract strength of 200.

none

Sets the affinity value to zero points.

Command Default

There are no default location-set affinities for any placeable processes.

Specifying an affinity value of default is equivalent to specifying the attract strength argument to be 200.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

The affinity location-set command assigns an affinity for a process to run on a specific node, node pair, or set of up to five nodes.

A node pair is either an active and standby pair of nodes [hosted on route processors (RPs) or distributed RPs], or a single active node on an RP or DRP that does not have a standby.

By containing references to specific location identifiers, location-set affinities are more specific to the individual SDR in which they are used than other affinity types.

RP/0/0RP0RSP0/CPU0:router(config-place)# affinity location-set 0/1/cpu0 0/1/cpu1 attract 200
         

The following example shows how to stop loading a DRP with more processes:


RP/0/0RP0RSP0/CPU0:router(config)# placement program default
RP/0/0RP0RSP0/CPU0:router(config-place)# affinity location-set 0/1/cpu0 repulse 90

affinity location-type


Note


Effective with Release 3.9.0, the affinity location-type command was deprecated.


To set the affinity of a placeable program (process) to or from a location type, use the affinity location-type command in placement program configuration mode. To remove the affinity of a location set, use the no form of this command.

affinity location-type { current | paired | primary } { attract strength | repulse strength | default | none }

noaffinity location-type { current | paired | primary } { attract strength | repulse strength | default | none }

Syntax Description

current

Affinity for the current location.

paired

Affinity for a node (or route processor) with a standby node.

primary

Affinity for the primary node.

attract

Specifies a positive affinity.

repulse

Specifies a negative affinity.

strength

A positive or negative strength. The range is from 1 to 100000 points.

default

Sets the affinity location-type default values.

none

Sets the affinity value to zero points.

Command Default

By default, all processes have the following settings:

  • location-type current attract strength argument: 100

  • location-type paired attract strength argument: 60

  • location-type primary attract strength argument: 40

Specifying an affinity value of default is equivalent to specifying the attract strength argument to be 200.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

The affinity location-type command is used to place a process at a particular location. The default policy is that the location type be a node pair (active and standby nodes), and that the process does not move automatically ( current = 100) unless a solo node fails and the process must be started on a different node.

You can configure the placement policy to allow certain processes to stay where they are (current) or move just by indicating so through the various affinity choices. The higher the positive value of an affinity, the stronger the requirement that the process run at a location, and so on. A low or zero point value would indicate a weaker requirement (or no preference) that a process run at a location.

The affinity location type with the paired option configures the affinity towards the nodes that are paired (active and standby nodes), and as mentioned earlier, this is the default policy. The affinity location type using the primary option configures the affinity towards the designated secure domain router shelf controller (DSDRSC) node. designated shelf controller (DSC) node.


Note


Change the current affinity with assistance from Cisco support personnel.

The affinity self command is used to adjust placement decisions when multiple instances of a process are started. An attract (positive) affinity indicates a preference to have all instances of a process run on the same node, while a repulse (negative) affinity indicates a preference to have each instance of a process run on different nodes.

Typically, you would want to monitor how a process on your system best performs, and whether instances of the same class should be collocated or not.

When a process crashes on the Cisco IOS XR software, a core dump file of the event is written to a designated destination without bringing down the router. Upon receiving notification that a process has terminated abnormally, the Cisco IOS XR software then respawns the crashed process. Core dump files are used by Cisco Technical Support Center engineers and development engineers to debug the Cisco IOS XR software.

Core dumps can be generated manually for a process, even when a process has not crashed. Two modes exist to generate a core dump manually:

  • running —Generates a core dump for a running process. This mode can be used to generate a core dump on a critical process (a process whose suspension could have a negative impact on the performance of the router) because the core dump file is generated independently, that is, the process continues to run as the core dump file is being generated.

  • suspended —Suspends a process, generates a core dump for the process, and resumes the process. Whenever the process is suspended, this mode ensures data consistency in the core dump file.

Core dump files contain the following information about a crashed process:

  • Register information

  • Thread status information

  • Process status information

  • Selected memory segments

Syntax Description

choice preference

(Optional) Configures the order of preference for the destination of core dump files. Up to the three destinations can be defined. Valid values are 1 to 3.

compress {on | off}

(Optional) Specifies whether or not the core dump file should be sent compressed. By default, core dump files are sent compressed. If you specify the compress keyword, you must specify one of the following required keywords:

  • on —Compresses the core dump file before sending it.

  • off —Does not compress the core dump file before sending it.

filename filename lower-limit-higher-limit

(Optional) Specifies the filename to be appended to core dump files and the lower and higher limit range of core dump files to be sent to a specified destination before being recycled by the circular buffer.

filename filename lower-limit-higher-limit See Table 1 for a description of the default core dump file naming convention.

Vali filename filename lower-limit-higher-limit d values for the lower-limit argument are 0 to 4. Valid values for the higher-limit argument are 5 to 64. A hyphen ( - ) must immediately follow the lower-limit argument.

Note   

To uniquely identify each core dump file, a value is appended to each core dump file, beginning with the lower limit value configured for the lower-limit argument and continuing until the higher limit value configured for the higher-limit argument has been reached. After the higher limit value has been reached, the Cisco IOS XR software begins to recycle the values appended to core dump files, beginning with the lower limit value.

filepath-name

Local file system or network protocol, followed by the directory path. All local file systems are supported. The following network protocols are supported: TFTP and FTP.

Command Default

If you do not specify the order of preference for the destination of core dump files using the choice preference keyword and argument, the default preference is the primary location or 1.

Core dump files are sent compressed.

The default file naming convention used for core dump files is described in Table 1.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Use the exception filepath command to modify core dump settings, such as the destination file path to store core dump files, file compression, and the filename appended to core dumps.

Up to three user-defined locations may be configured as the preferred destinations for core dump files:

  • Primary location—The primary destination for core dump files. Enter the choice keyword and a value of 1 (that is, choice 1 ) for the preference argument to specify a destination as the primary location for core dump files.

  • Secondary location—The secondary fallback choice for the destination for core dump files, if the primary location is unavailable (for example, if the hard disk is set as the primary location and the hard disk fails). Enter the choice keyword and a value of 2 (that is, choice 2 ) for the preference argument to specify a destination as the secondary location for core dump files.

  • Tertiary location—The tertiary fallback choice as the destination for core dump files, if the primary and secondary locations fail. Enter the choice keyword and a value of 3 (that is, choice 3 ) for the preference argument to specify a destination as the tertiary location for core dump files.

When specifying a destination for a core dump file, you can specify an absolute file path on a local file system or on a network server. The following network protocols are supported: TFTP and FTP.


Note


We recommend that you specify a location on the hard disk as the primary location.


In addition to the three preferred destinations that can be configured, Cisco IOS XR software provides three default fallback destinations for core dump files in the event that user-defined locations are unavailable.

The default fallback destinations are:

  • harddisk:/dumper

  • disk1:/dumper

  • disk0:/dumper

  • disk1:/dumper

  • disk0:/dumper

  • bootflash:/dumper


Note


If a default destination is a boot device, the core dump file is not sent to that destination.


We recommend that you configure at least one preferred destination for core dump files as a preventive measure if the default fallback paths are unavailable. Configuring at least one preferred destination also ensures that core dump files are archived because the default fallback destinations store only the first and last core dump files for a crashed process.


Note


Cisco IOS XR software does not save a core file on a local storage device if the size of the core dump file creates a low-memory condition.


By default, Cisco IOS XR software assigns filenames to core dump files according to the following format:

process [.by. requester |.abort][.sparse]. date-time . node . processor-type [.Z]

For example:

 packet.by.dumper_gen.20040921-024800.node0_RP0_CPU0.ppc.Z 
  

Table 1 describes the default core dump file naming convention.

Table 1  Default Core Dump File Naming Convention Description

Field

Description

process

Name of the process that generated the core dump.

.by. requester | .abort

If the core dump was generated because of a request by a process (requester), the core filename contains the string “.by.requester” where the requester variable is the name or process ID (PID) of the process that requested the core dump. If the core dump was due to a self-generated abort call request, the core filename contains the string “.abort” instead of the name of the requester.

.sparse

If a sparse core dump was generated instead of a full core dump, “sparse” appears in the core dump filename.

.date-time

Date and time the dumper process was called by the process manager to generate the core dump. The .date-time time-stamp variable is expressed in the yyyy.mm.dd-hh.mm.ss format. Including the time stamp in the filename uniquely identifies the core dump filename.

. node

Node ID, expressed in the rack/slot/module notation, where the process that generated the core dump was running.

.processor-type

Type of processor (mips or ppc).

.Z

If the core dump was sent compressed, the filename contains the .Z suffix.

You can modify the default naming convention by specifying a filename to be appended to core dump files with the optional filename filename keyword and argument and by specifying a lower and higher limit ranges of values to be appended to core dump filenames with the lower-limit and higher-limit arguments, respectively. The filename that you specify for the filename argument is appended to the core dump file and the lower and higher limit ranges of core dump files to be sent to a specified destination before the filenames are recycled. Valid values for the lower-limit argument are 0 to 4. Valid values for the higher-limit argument are 5 to 64. A hyphen ( - ) must immediately follow the lower-limit argument. In addition, to uniquely identify each core dump file, a value is appended to each core dump file, beginning with the lower-limit value specified with the lower-limit argument and continuing until the higher-limit value specified with the higher-limit argument has been reached. When the configured higher-limit value has been reached, Cisco IOS XR software begins to recycle the values appended to core dump files, beginning with the lower-limit value.

Examples

The following example shows how to configure the core dump setting for the primary user-defined preferred location. In this example, core files are configured to be sent uncompressed; the filename of core dump files is set to “core” (that is, all core filenames will be named core); the range value is set from 0 to 5 (that is, the values 0 to 5 are appended to the filename for the first five generated core dump files, respectively, before being recycled); and the destination is set to a directory on the hard disk.

The following example shows how to use the command:

RP/0/RP1/CPU0:Linkwood(config)#exception filepath f1
RP/0/RP0/CPU0:router(config)# exception choice 1 compress off
  filename core 0-5 filepath /harddisk:/corefile

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Use the exception sparse command to reduce the amount of data generated in the core dump file. Sparse core dumps reduce the amount of time required to generate the core dump file because only referenced data is generated in the core file (at the cost of lost information in the core file). Reducing the time required to generate core dump files corresponds to faster process restart times.

Sparse core dumps contain the following information about crashed processes:

  • Register information for all threads, and any memory pages referenced in these register values

  • Stack information for all threads, and any memory pages referenced in these threads

  • All memory pages referenced by a loaded dynamic loadable library (DLL) data section, if the final program counter falls in a DLL data section

  • Any user-specified marker pages from the lib_dumper_marker DLL

The exception sparse command dumps memory pages based on trigger addresses found in the previously listed dump information, according to the following criteria:

  • If the trigger address in the memory page is in the beginning 128 bytes of the memory page, the previous memory page in the continuous address region is dumped also.

  • If the trigger address in the memory page is in the final 128 bytes of the memory page, the next memory page in the continuous address region is dumped also.

  • In all other instances, only the memory page that includes the trigger address is dumped.


Note


Use the exception sparse off command in administration configuration mode to get a complete coredump of the transient processes on the RP.

Usage Guidelines

Use this command to unintrusively debug a live process or a live thread in a process. This command is particularly useful for debugging deadlock and livelock conditions, for examining the contents of a memory location or a variable in a process to determine the cause of a corruption issue, or in investigating issues where a thread is stuck spinning in a loop. A livelock condition is one that occurs when two or more processes continually change their state in response to changes in the other processes.

The following actions can be specified with this command:

  • Follow all live threads of a given process or a given thread of a process and print stack trace in a format similar to core dump output.

  • Follow a process in a loop for a given number of iterations.

  • Set a delay between two iterations while invoking the command.

  • Set the priority at which this process should run while this command is being run.

  • Dump memory from a given virtual memory location for a given size.

  • Display register values and status information of the target process.

Take a snapshot of the execution path of a thread asynchronously to investigate performance-related issues by specifying a high number of iterations with a zero delay.

placement memory


Note


Effective with Release 3.9.0, the placement memory command was deprecated.


To set the process memory threshold, use the placement memory command in global configuration or administration configuration mode. To return the settings to the default value, use the no form of this command.

placement memory { maximum max-value | threshold threshold-value }

no placement memory

Syntax Description

maximum max-value

Defines the maximum memory load level, as a percentage. The value can be 10 to 2000. The default value is 200.

threshold threshold-value

Defines the memory load level to trigger migration, as a percentage. The value can be 10 to 400. The default value is 80.

Command Default

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Use the placement memory command with the maximum value keyword and argument to set the maximum percentage of memory that can be used on a node (based on the estimated memory usage of the processes). For example:

  • The placement memory maximum 100 command sets the maximum memory usage on nodes to 100 percent. If a node has 2 GB of available memory, then only 2 GB of processes can be placed on the node (estimated memory usage). This means that oversubscription is not allowed.

  • The placement memory maximum 50 command sets the maximum memory usage on nodes to 50 percent, so that placeable processes can use only half the memory on the node.

  • The placement memory maximum 200 command allows the system to attempt to run more than the available memory on a node.

Use the placement memory command with the threshold value keyword and argument to set the preferred percentage of memory use for each node. The system attempts to balance all nodes at or below the threshold memory percentage. In other words, the system does not place a process on a node that has exceeded the threshold value, unless all other nodes have also reached their thresholds (or unless some other large affinity overrides this consideration).

Use the show placement command with the policy global keywords to display the current settings:

RP/0/0RP0RSP0/CPU0:router# show placement policy global

Per-location placement policy parameters
----------------------------------------
Memory preferred threshold:      80%
Memory maximum threshold:       200%
Threshold satisfaction affinity points:    50

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

The placement program command allows you to change the placement policy for any placeable process, such as Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP).

Placement policy consists of two types: resource consumption and affinities. Resource consumption involves CPU and memory usage and is a “hard” resource requirement. Affinities are preferences and are considered “soft” requirements for a placement policy. Only affinities can be configured by the operator.

The placement program command handles configuration for these affinity types:

  • Affinity location set

  • Affinity location type

  • Affinity program

  • Affinity self

  • Affinity existence

To obtain a list of running placeable processes and placement policy parameters on your router system, use the show placement policy command.

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

The show placement policy command displays placement policy items that influence program or process placement. The global option lists the per node threshold parameters, and the remaining options list the policy based on program.

If you configured the placement policy, the scope could be the default program, a given program, or even a particular program instance. Alternatively, the policy could be specified in a placement file (entered by the system) with different levels of affinities. To view all this information, you can specify the program all option to display the source of each program, and the policy applied to the default program or the program that you configured to override it.

Examples

The following example shows that all placement programs are running on the node pair 0/RP0/CPU0 and 0/RP1/CPU0:

RP/0/0RP0RSP0/CPU0:router# show placement program all

Mon Aug 18 17:13:15.155 PST DST

If a program is shown as having 'rejected locations' (i.e., locations on which
it cannot be placed), the locations in question can been seen using the "show
placement policy program" command.

If a program has been placed but not yet started, the amount of time elapsed
since the program was placed is shown in the 'waiting to start' field.

Parentheses around the node indicate that the node has not yet fully booted.
  This will be true of standby nodes.

Table 16  show processes memory Field Descriptions

Field

Description

JID

Job ID.

PID

Process ID.

Text

Size of text region (process executable).

Data

Size of data region (initialized and uninitialized variables).

Stack

Size of process stack.

Dynamic

Size of dynamically allocated memory.

Process

Process name.

The show processes command with the all keyword displays summary information for all processes, as shown in the following example:
RP/0/0RP0RSP0/CPU0:router# show processes all

Table 17  show processes all Field Description

Field

Description

JID

Job ID.

PID

Process ID.

Last Started

Date when the process was last started.

State

State of the process.

Restart

Number of times the process has restarted since the node was booted. If a node is reloaded, the restart count for all processes is reset. Normally, this value is 1, because usually processes do not restart. However, if you restart a process using the process restart command, the restart count for the process increases by one.

Placement

Indicates whether the process is a placeable process or not. Most processes are not placeable, so the value is blank. ISIS, OSPF, and BGP are examples of placeable processes.

Mandatory

M indicates that the process is mandatory. A mandatory process must be running. If a mandatory process cannot be started (for example, sysmgr starts it but it keeps crashing), after five attempts the sysmgr causes the node to reload in an attempt to correct the problem. A node cannot function properly if a mandatory process is not running.

Maint Mode

Indicates processes that should be running when a node is in maintenance mode. Maintenance mode is intended to run as few processes as possible to perform diagnostics on a card when a problem is suspected. However, even the diagnostics require some services running.

Name (IID)

Name of the process followed by the instance ID. A process can have multiple instances running, so the IID is the instance ID.

Args

Command-line arguments to the process.


Related Commands

Description

monitor processes

Displays auto-updating statistics on processes in a full-screen mode.

monitor threads

Displays auto-updating statistics on threads in a full-screen mode.

slow-migration-interval

To set the slow migration interval for the program, use the slow-migration-interval command in placement program configuration mode. To return the slow migration interval to its default value, use the no form of this command.

slow-migration-interval length

no slow-migration-interval

Syntax Description

length

Length of the slow migration interval, in seconds. The default is 1 second.

Command Default

The default slow migration interval is 1 second.

Command Modes

Placement program configuration

Command History

Release

Modification

Release 3.3.0

This command was introduced.

Release 3.7.2

This command was introduced.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

The placement reoptimize command identifies processes that must be moved to achieve optimal placement. To prevent disruption on the router, you can use the slow-migration-interval command to specify the time to wait after moving each process, to allow the router to recover before preceding to move the next process.

Task ID

Task ID

Operations

sysmgr

read, write

Examples

This example shows how to set the slow migration interval:

RP/0/0RP0RSP0/CPU0:router(config)# placement program ipv4_rib
RP/0/0RP0RSP0/CPU0:router(config-place)# slow-migration-interval 240
