Chapter 1 Overview
PIX Firewall System Requirements
Flash Memory Requirements
Table 1-2
lists Flash memory requirements for PIX Firewall software Version 6.3 in conjunction with
PDM Version 3.0 by platform.
Maximum Configuration File Size
For optimum performance, we recommend a configuration file of no more than 100 KB (approximately
1500 lines) when using PDM.
PIX Firewall configuration files over 100 KB may interfere with the performance of PDM on your
workstation in the following situations:
•
While executing commands such as write term and show conf
•
Failover (the configuration synchronization time)
•
During a system reload
To determine the size of your configuration file, enter the show flashfs command at the PIX Firewall
CLI prompt. View the output which begins with “file 1.” The number labeled “length” on the same line
is the configuration file size in bytes.
For example:
pixfirewall# show flashfs
flash file system: version:3 magic:0x12345679
file 0:origin: 0 length:1925176
file 1:origin:2883584 length:2944
file 2:origin:3014656 length:32
file 3:origin: 0 length:0
file 4:origin:3145728 length:131072
file 5:origin:8257536 length:308
