Port Monitoring

RAM Disk System for Data Capture Files
Port monitoring uses a
RAM
disk for fast temporary storage of data capture files. The
RAM
disk
has a separate directory designation of
/ram
.
RAM
-based files are created in
DOS-FAT
format
and they are displayed in
UPPERCASE
.
You can copy files between the
/ram
disk system and the standard
/flash
file system. In addi-
tion, files in the
RAM
disk system are retrievable via
FTP
. Both the
/ram
file system and the
/flash
file system are accessible by using the
UNIX/DOS
-style change directory (
cd
) command.
♦
Note
♦
The
RAM
drive is part of
DRAM
memory. If you power
off or reboot the switch, any files saved in the
RAM
drive will be lost.
Configuring RAM Drive Resources (pmcfg)
The
pmcfg
command allows you to select the size of the
RAM
disk file system or to delete the
RAM
disk. In addition, it allows you to configure the amount of data collected for each packet
capture. To begin configuring
RAM
drive resources, enter
pmcfg
A screen similar to the following displays:
RAM disk size : 1000 Kilobytes
Lines displayed: 1
Change any of the above (y/n)? (n)
To change one of the settings, enter a
Y
and press
<enter>
. You will be prompted for a new
RAM
drive size. Select a size in kilobytes between 1000 and 8000. You can also delete the
RAM
drive by entering a size of zero (0). Changing the
RAM
disk size also requires that you
reboot the system.
The
Lines displayed
controls the amount of data displayed to the terminal when you choose to
dump session data to the computer screen. You can specify the number of lines to display
while viewing port monitor data on the screen.
Changing the Default System Directory (cd)
After a port monitoring session is enabled the default directory is the
RAM
disk system (
/ram
).
To switch back to the standard default flash file system (
/flash
) use the
cd
command. To
switch back to the default directory, enter
cd /flash
To switch back to the
RAM
disk directory, enter
cd /ram
