Description
Electrically erasable programmable read-only memory (EEPROM) on the
•
supervisor engine or route switch processor stores module-specific information,
such as the serial number, part number, controller type, hardware revision,
configuration information, and other details unique to each module.
• NVRAM for storing configuration information.
• DRAM for default system software.
For the RSP720-GE and the RSP720-10GE:
RP Memory: 1 to 4 GB DRAM (default is 1 GB for the 3C version and 2GB
–
for the 3CXL version)
– SP: 1 to 2 GB DRAM (default is 1 GB)
– WS-SUP720 supports 512MB of DRAM for the route processor and 512 MB
for the switch processor
– WS-SUP720-3B supports 512MB of DRAM for the route processor and 512
MB for the switch processor, upgradeable to 1GB
WS-SUP720-3BXL supports 1GB DRAM for route the processor and 1GB
–
DRAM for the switch processor
To support installation of new software releases from 12.2(33)SRE onwards
Note
in SUP720, RSP720-GE, and RSP720-10GE, ensure that you increase the
DRAMS to 1024MB for SP and RP.
Internal flash memory—To store the boot image. The defaults are:
•
The RSP720 SP/RP and the Sup32 SP contain a CompactFlash (CF) adapter
•
that provides 512 MB of internal flash memory.
The Sup720 SP/RP, Sup32 RP, and Sup2 SP/RP contain 32-MB or 64-MB of
•
internal flash memory. Cisco IOS Release 12.2(18)SXF and later releases
support the CF adapter as an orderable option (Cisco part number
CF-ADAPTER=) for these Sups.
In the command-line-interface (CLI), you access internal flash memory as
Note
bootdisk (CF adapter) or bootflash (non-CF adatper). When you install a CF
adapter on the Sup720, Sup32, or Sup2, bootflash becomes an alias to
bootdisk.
• External flash memory—To store and run software images and configuration files
or to serve as an input/output (I/O) device. You can install 64-MB, 128-MB,
256-MB, 512-MB, or 1 GB flash memory cards, or 1-GB MicroDrive card, in slots
on the supervisor engine or RSP front panel. For information on using flash
memory, see Using Flash Memory Cards, page
The RSP720 and RSP720-10GE support 1G external compact flash from Cisco
IOS Release 12.2(33)SRD1 release onwards. (Previously, 512MB was the
maximum external compact flash.
The Sup2 supports PCMCIA flash memory cards only. It does not support
CompactFlash or MicroDrive cards.
• Flash file system—Flash memory contains a file system. You can use a variety of
commands to manage the file system (such as cd, pwd, dir, and delete). The file
system includes the following devices:
