Router Memory Commands

---

This chapter provides detailed descriptions of the commands used to maintain router memory.

For configuration information and examples, refer to the "Maintaining Router Memory" chapter in the Release 12.2 Cisco IOS Configuration Fundamentals Configuration Guide.

Flash Memory File System Types

Cisco platforms generally use one of three different Flash memory file system type. Some commands are supported on only one or two file system types.

Use Table 36 to determine which Flash memory file system type your platform uses.

Table 36 Flash Memory File System Types

Type	Platforms
Class A	Cisco 7000 family, Cisco 12000 series, LightStream LS1010 series
Class B	Cisco 1003, Cisco 1004, Cisco 1005, Cisco 2500 series, Cisco 3600 series, Cisco 4000 series, Cisco AS5200 access servers
Class C	Cisco MC3810 multiservice concentrators; disk0 and disk1 of Cisco SC3640 system controllers

memory scan

To enable the Memory Scan feature on a Cisco 7500 series router, use the memory scan command. To restore the router configuration to the default, use the no form of this command.

memory scan

no memory scan

Syntax Description

This command has no arguments or keywords.

Defaults

This command is disabled by default.

Command Modes

Global configuration

Command History

Release	Modification
12.0(4)XE	This command was introduced.
12.0(7)T	This command was integrated in Cisco IOS Release 12.0 T.

Usage Guidelines

The Memory Scan feature adds a low-priority background process that searches all installed dynamic random-access memory (DRAM) for possible parity errors. If errors are found in memory areas that are not in use, this feature attempts to scrub (remove) the errors. The time to complete one memory scan and scrub cycle can range from 10 minutes to several hours, depending on the amount of installed memory. The impact of the Memory Scan feature on the central processing unit (CPU) is minimal. To view the status of the memory scan feature on your router, use the show memory scan command in EXEC mode.

Examples

The following example enables the Memory Scan feature on a Cisco 7500 series router:

Router(config)# memory scan

Related Commands

Command	Description
show memory scan	Displays the number and type of parity errors on your system (Cisco 7500 series only).

memory-size iomem

To reallocate the percentage of DRAM to use for I/O memory and processor memory on Cisco 3600 series routers, use the memory-size iomem global configuration command. To revert to the default memory allocation, use the no form of this command.

memory-size iomem i/o-memory-percentage

no memory-size iomem i/o-memory-percentage

Syntax Description

i/o-memory-percentage

The percentage of DRAM allocated to I/O memory. The values permitted are 10, 15, 20, 25, 30, 40, and 50. A minimum of 4 MB of memory is required for I/O memory.

Defaults

The default memory allocation is 25 percent I/O memory and 75 percent processor memory.

---

Note If the smartinit process has been enabled, the default memory allocation of 25% to I/O does not apply. Instead, smartinit examines the network modules and then calculates the I/O memory required.

---

Command Modes

Global configuration

Command History

Release	Modification
11.2 P	This command was introduced.

Usage Guidelines

When you specify the percentage of I/O memory in the command line, processor memory automatically acquires the remaining percentage of DRAM memory.

Examples

The following example allocates 40 percent of the DRAM memory to I/O memory and the remaining 60 percent to processor memory:

Router# configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)# memory-size iomem 40

Router(config)# exit

Router# copy system:running-config nvram:startup-config

Building configuration...

[OK]

Router# reload

rommon 1 > boot

partition

To separate Flash memory into partitions on Class B file system platforms, use the partition global configuration command. To undo partitioning and to restore Flash memory to one partition, use the no form of this command.

Cisco 1600 Series and Cisco 3600 Series Routers

partition flash-filesystem: [number-of-partitions][partition-size]

no partition flash-filesystem:

All Other Class B Platforms

partition flash partitions [size1 size2]

no partition flash

Syntax Description

flash-filesystem:	One of the following Flash file systems, which must be followed by a colon (:). The Cisco 1600 series can only use the flash: keyword. •flash:—Internal Flash memory •slot0:—Flash memory card in PCMCIA slot 0 •slot1:—Flash memory card in PCMCIA slot 1
number-of-partitions	(Optional) Number of partitions in Flash memory.
partition-size	(Optional) Size of each partition. The number of partition size entries must be equal to the number of specified partitions.
partitions	Number of partitions in Flash memory. Can be 1 or 2.
size1	(Optional) Size of the first partition (in megabytes).
size2	(Optional) Size of the second partition (in megabytes).

Defaults

Flash memory consists of one partition.

If the partition size is not specified, partitions of equal size are created.

Command Modes

Global configuration

Command History

Release	Modification
10.3	This command was introduced.

Usage Guidelines

For the Cisco 1600 series and Cisco 3600 series routers, to undo partitioning, use the partition flash-filesystem:1 or no partition flash-filesystem: command. For other Class B platforms, use either the partition flash 1 or no partition flash command. If there are files in a partition other than the first, you must use the erase flash-filesystem:partition-number command to erase the partition before reverting to a single partition.

When creating two partitions, you must not truncate a file or cause a file to spill over into the second partition.

Examples

The following example creates two partitions of 4 MB each in Flash memory:

Router(config)# partition flash 2 4 4

The following example divides the Flash memory card in slot 0 into two partitions, each 8 MB in size on a Cisco 3600 series router:

Router(config)# partition slot0: 2 8 8

The following example creates four partitions of equal size in the card on a Cisco 1600 series router:

Router(config)# partition flash: 4

show (Flash file system)

To display the layout and contents of a Flash memory file system, use the show EXEC command.

Class A Flash File Systems

show flash-filesystem: [all | chips | filesys]

Class B Flash File Systems

show flash-filesystem: [partition number] [all | chips | detailed | err | summary]

Class C Flash File Systems

show flash-filesystem:

Syntax Description

flash-filesystem:	Flash memory file system (bootflash:, flash:, slot0:, slot1:, slavebootflash:, slaveslot0:, or slaveslot1:), followed by a colon.
all	(Optional) On Class B Flash file systems, all keyword displays complete information about Flash memory, including information about the individual ROM devices in Flash memory and the names and sizes of all system image files stored in Flash memory, including those that are invalid. On Class A Flash file systems, the all keyword displays the following information: •The information displayed when no keywords are used. •The information displayed by the filesys keyword. •The information displayed by the chips keyword.
chips	(Optional) Displays information per partition and per chip, including which bank the chip is in, plus its code, size, and name.
filesys	(Optional) Displays the Device Info Block, the Status Info, and the Usage Info.
partition number	(Optional) Displays output for the specified partition number. If you do not specify a partition in the command, the router displays output for all partitions. You can use this keyword only when Flash memory has multiple partitions.
detailed	(Optional) Displays detailed file directory information per partition, including file length, address, name, Flash memory checksum, computer checksum, bytes used, bytes available, total bytes, and bytes of system Flash memory.
err	(Optional) Displays write or erase failures in the form of number of retries.
summary	(Optional) Displays summary information per partition, including the partition size, bank size, state, and method by which files can be copied into a particular partition. You can use this keyword only when Flash memory has multiple partitions.

Command Modes

EXEC

Command History

Release	Modification
11.3 AA	This command was introduced.

Usage Guidelines

If Flash memory is partitioned, the command displays the requested output for each partition, unless you use the partition keyword.

The command also specifies the location of the current image.

To display the contents of boot Flash memory on Class A or B file systems, use the show bootflash: command as follows:

Class A Flash file systems

show bootflash: [all | chips | filesys]

Class B Flash file systems

show bootflash: [partition number] [all | chips | detailed | err]

To display the contents of internal Flash memory on Class A or B file systems, use the show flash: command as follows:

Class A Flash file systems

show flash: [all | chips | filesys]

Class B Flash file systems

show flash: [partition number][all | chips | detailed | err | summary]

The show (Flash file system) command replaces the show flash devices command.

Examples

The output of the show command depends on the type of Flash file system you select. Types include flash:, bootflash:, slot0:, slot1:, slavebootflash:, slaveslot0:, and slaveslot1:.

Examples of output from the show flash command are provided in the following sections:

•Class A Flash File System

•Class B Flash File Systems

Although the examples use flash: as the Flash file system, you may also use the other Flash file systems listed.

Class A Flash File System

The following three examples show sample output for Class A Flash file systems. Table 37 describes the significant fields shown in the display.

The following is sample output from the show flash: command.
