SP Switch Router command overview
SP Switch Router command overview
This section provides a brief overview of frequently-used management commands. These are
administrative and configuration commands, most are prefixed with gr and most operate on the
router’s internal flash.
These commands manage memory and support multiple configuration versions. These include:
flashcmd, getver, grfins, grsite, grsnapshot, grwrite, mountf, setver, umountf, and vpurge.
Refer to the GRF Reference Guide for command syntax and examples. Man pages are available
for most of these commands.
Many of the commands read/write the internal flash device. Those commands will mount the
flash (mountf -w), perform their function, and then unmount the flash. Mounting takes several
seconds. If you are doing several commands in a row, mount the flash yourself to avoid the
repeated mount/unmount delay. The commands do not mount flash if it is already mounted and
do not unmount it if they did not mount it.
This diagram of the control board memory structure provides a reference point as you review
the memory commands.

csconfig
csconfig sets a PCMCIA slot interface on (up) or off (down), and reports general interface and
device status. This command is useful for remote management of PCMCIA devices to verify
the status of device and slot interface readiness.
flashcmd
This SP Switch Router command mounts the specified flash device, executes a command (such
as write, read, ls, df) on the device, and then unmounts the device. For example, to use the df
command to determine device capacity, use flashcmd df.
