Process and Memory Management Commands on Cisco IOS XR Software
This chapter describes the Cisco IOS XR software commands used to manage processes and memory.
For more information about using the process and memory management commands to perform troubleshooting tasks, see the Cisco IOS XR Getting Started Guide.
affinity location-set
To set the affinity of a placement 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-id1 [node-id2] {attract strength | repulse strength | default | none}
no affinity location-set node-id1 [node-id2] {attract strength | repulse strength | default | none}
Syntax Description
node-id1 [node-id2]
|
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
|
A positive or negative strength. The range is from 1 to 100000 points.
|
default
|
Sets the affinity location-set default value.
|
none
|
Sets the affinity value to zero points.
|
Defaults
The affinity location set value is 200 points.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
The affinity location-set command assigns an affinity for a process to run on a specific node, node pair or set of up to 5 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.
You can use this command to override the placement process logic for determining optimal placement for processes. It forces a process to remain in or away from a location on the router regardless of what might occur in the system. This command also makes the configuration more specific to a router and less general.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
The affinity location-type command is used to a place 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 Logical Router System Controller (dLRSC) 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.
On 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. Because 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

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
Use the exception dump-tftp-route command to configure the TFTP server on the RP to receive kernel core dumps from MSCs and SPs. Once the TFTP server is configured, use the exception kernel memory command to define the filename for the core dump, the type of memory to collect, and the destination (local or remote) where kernel core dumps will be stored.
Command modes in the Cisco CRS-1
On a Cisco CRS-1 router, the exception dump-tftp-route command can be run from either global configuration mode or Administration configuration mode.
•
To configure the TFTP server on the RP to receive kernel core dumps from MSCs, issue this command from global configuration mode.
•
To configure the TFTP server on the RP to receive kernel core dumps from SPs, issue this command from Administration configuration mode.
•
Issue the command from both global configuration and Administration configuration mode to gather kernel core dumps from all nodes.
Command modes in the Cisco XR 12000 Series Router
On Cisco XR 12000 Series Routers, the exception dump-tftp-route command can only be run from global configuration mode. This configures the TFTP server on the RP to receive kernel core dumps from MSCs.
Note
SPs are not supported on the Cisco XR 12000 Series Router. In effect, configuring the TFTP server on the RP to receive kernel core dumps from MSCs gathers kernel core dumps from all nodes.

Examples
In the following example, the exception kernel memory command is used to enable the collection of kernal core dumps, and the hard disk as the destination for kernel core dumps. The exception dump-tftp-route command is then used to configure the TFTP server on the RP to receive kernel core dumps from MSCs and SPs. This example is for a Cisco CRS-1 router.
RP/0/RP0/CPU0:router(config)# exception kernel memory kernel filepath harddisk:
RP/0/RP0/CPU0:router(config)# exception dump-tftp-route port 0 host-address 10.0.2.1/16

Related Commands
exception filepath
To modify core dump settings, use the exception filepath command in Administration configuration mode or in global configuration mode. To remove the configuration, use the no form of this command.
exception [choice preference] [compress {on | off}] [filename filename lower-limit-higher-limit]
filepath filepath
no exception [choice preference] [compress {on | off}] [filename filename
lower-limit-higher-limit] [filepath filepath]
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.
See Table 1 in the "Usage Guidelines" section for a description of the default core dump file naming convention.
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.
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
|
The 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.
|
Defaults
If you do not specify the order of preference for the destination of core dump files using the choice keyword and preference argument, the default preference is the primary location (that is, choice 1).
Core dump files are sent compressed.
The default filenaming convention used for core dump files is described in the "Usage Guidelines" section. See Table 1.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
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 files, 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 on the Cisco CRS-1.
In addition to the three preferred destinations that can be configured, the 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 on the Cisco CRS-1 is:
•
harddisk:/dumper
•
disk1:/dumper
•
disk0:/dumper
The default fallback destinations on Cisco XR 12000 Series Routers are:
•
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
The 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, the 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 filenaming convention.
Table 1 Default Core Dump Filenaming 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 will contain 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 keyword and filename 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 keyword has been reached. When the configured 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.

The exception kernel memory command is used with the exception dump-tftp-route command. The exception dump-tftp-route command configures the TFTP server on the route processor (RP) to receive kernel core dumps from modular service cards (MSCs) or service processors (SPs). The exception kernel memory command specifies the core dump settings, including the following:
•
The type of kernel collected in kernel core dump files.
•
(Optional) The filename of the kernel core dump files.
•
The destination for kernel core dump files.
Command modes in the Cisco CRS-1
On a Cisco CRS-1 router, the exception kernel memory command can be issued from global configuration mode or Administration configuration mode:
•
Issuing this command from global configuration mode enables the collection of kernel core dumps for MSCs.
•
Issuing this command from Administration configuration mode enables the collection of kernel core dumps for SPs.
•
Enabling this command in both global configuration mode and Administration configuration mode ensures the collection of all kernel dumps.
Command modes in the Cisco XR 12000 Series Router
On Cisco XR 12000 Series Routers, the exception kernel memory command can only be run from global configuration mode. This enables the collection of kernel core dumps for MSCs.
Note
SPs are not supported on the Cisco XR 12000 Series Router. In effect, enabling core dumps from MSCs enables core dumps for all nodes.
Kernel core dump filename
By default, the filename "kernel_core" is appended to kernel core dumps. To modify the filename appended to kernel core dump files, use the filename keyword and filename argument.
Filepath for core dump files
There is no default destination for kernel core dump files. You must specify a destination by using the filepath keyword and filepath argument. You can specify an absolute file path on a local file system or on a network server.

Use the exception sparse command to reduce the amount of data generated in the core dump file. Sparse core dumps, thus, 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
•
Stack information for all threads
•
Process executable text and data information
•
All loaded dynamic loadable library (DLL) text and thread information
Pages referenced from the top 512 bytes of the stack of any thread, the stack of a crashed threads, and register information of threads from the data section of a process and from the section of the DLL that contains the function that caused the crash to occur.

Use the exception sprsize command to specify the maximum file size for core dumps. The maximum file size configured for the megabytes argument is used with the configuration set for the exception sparse command to determine whether or not to generate a sparse core dump file. If sparse core dumps are disabled and a core dump file is predicted to exceed the default value (192 MB) uncompressed or the value specified for the megabytes argument uncompressed, a sparse core dump file is generated. If sparse core dumps are enabled, a sparse core dump file is generated, regardless of the size of the core dump file.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
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 command placement memory maximum 100 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 command placement memory maximum 50 sets the maximum memory usage on nodes to 50 percent, so that placeable processes can use only half the memory on the node.
•
The command placement memory maximum 200 would allow 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 policy global command to display the current settings:
RP/0/RP0/CPU0:router#show placement policy global
Per-location placement policy parameters

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
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.

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/RP0/CPU0:router# show placement program all
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.
