Symptom
PDM launches slowly.
Performance of PDM is slow.
There is access only to the Monitoring
tab in PDM.
Cisco PIX Device Manager Installation Guide
5-6
Conditions
The startup speed of PDM depends on
the amount of available RAM in your
computer and whether virus scanning
software is running on your computer.
When using the Java Plug-in and
accessing your PIX Firewall using an IP
address instead of a host name, the
performance of PDM is dramatically
slower. This occurs if the PIX Firewall
host name is not in DNS or in the local
hosts file.
The use of certain PIX Firewall CLI
commands, and certain command
combinations, limit access in PDM to
the Monitoring tab.

Workaround
You can increase your available RAM
1.
by closing other applications.
The time required to download the
2.
PDM applet can be greatly affected by
the speed of the link between your
workstation and the PIX Firewall unit.
A minimum of 56 Kbps link speed is
required; however, 3.84 Mbps or
higher is recommended. Once the
PDM applet is loaded on your
workstation, the link speed impact on
PDM operation is negligible.

"PC/Workstation Requirements"
Chapter 1.
Assure that the PIX Firewall host name is
in DNS. If you are running Windows, and
there is no DNS in your network or your
DNS does not have the PIX Firewall entry,
modify the "hosts" file.
On Windows NT, 2000, and XP, the
•
hosts file is located at
C:\WINNT\system32\drivers\etc\host
s.
On Windows 98 and ME, it is at
•
C:\Windows\hosts.
Each line in the hosts file is in the format
"<ip> <hostname>". For example:
192.168.1.1
pixfirewall.example.com

and command combinations, see the Cisco
