This chapter describes the function and displays the syntax for router memory commands. For more information about defaults and usage guidelines, see the corresponding chapter of the Configuration Fundamentals Command Reference.
The copy source-url system:running-config command replaces the configure network command. Refer to the the copy command in this chapter for further details.
The copy source-url nvram: startup-config command replaces the configure overwrite-network command. Refer to the copy command in this chapter for further details.
To copy any file from a source to a destination, use the copy EXEC command.
copy [/erase] source-url destination-url
/erase | (Optional) Erases the destination file system before copying. |
source-url | The location of the source file or directory to be copied. |
destination-url | The destination of the copied file or directory. |
The erase bootflash: and erase bootflash commands have identical function.
The erase flash: and erase flash commands have identical function.
To reallocate the percentage of DRAM memory to use for I/O memory and processor memory on Cisco 3600 series routers, use the memory-size iomem global configuration command. The no form of this command reverts to the default allocation of 25 percent I/O memory and 75 percent processor memory.
memory-size iomem i/o-memory-percentage
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 percent. A minimum of 4 MB of memory is required for I/O memory. |
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. |
To display the layout and contents of a Flash memory file system, use the show EXEC command:
show flash-filesystem: [all | chips | filesys] (Class A Flash file systems)
flash-filesystem | Flash memory file system (bootflash:, flash:, slot0:, slot1:, slavebootflash:, slaveslot0:, or slaveslot1:). |
all | (Optional) On Class B Flash file systems, all shows 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, all shows 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) Shows information per partition and per chip, including which bank the chip is in plus its code, size, and name. |
filesys | (Optional) Shows the Device Info Block, the Status Info, and the Usage Info. |
detailed | (Optional) Shows 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) Shows write or erase failures in the form of number of retries. |
partition number | (Optional) Shows 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. |
summary | (Optional) Shows 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. |
The copy system:running-config nvram: startup-config command replaces the write memory command. Refer to the copy command for further details.
The copy system:running-config destination-url command replaces the write network command. Refer to the copy command for further details.
