Cisco Cisco Catalyst 6500 Series Firewall Services Module 發佈版本通知

This section describes how to upgrade to the latest version, and includes the following topics:

For CLI procedures, see the ASA release notes.

The software version appears on the ASDM home page; view the home page to verify the software version 
of your FWSM.

Starting in Release 4.0(1), many commands are migrated to new commands (for example, the http-map 
commands are converted to policy-map type inspect http commands).

If you upgrade from 2.x or 3.x, the configuration is converted. This converted configuration is not saved 
to memory until you save the configuration by clicking Save at the top of the window.

If you try to downgrade to 2.x or 3.x using a converted configuration, many commands will be rejected. 
Moreover, if you add access lists to the 4.x configuration to take advantage of larger access list memory 
space, then downgrading could result in an inability to load all the new access lists.

If you want to downgrade, be sure to copy a saved 2.x or 3.x configuration to the starting configuration 
before you reload with the 2.x or 3.x image.

Crashinfo enhancement

The crashinfo enhancement improves the reliability of generating crash information.

No screens were modified.

Packet Capture Wizard

The FWSM uses the Packet Capture Wizard to implement a packet sniffer on the FWSM. Cisco 
TAC might request captures from you to troubleshoot a problem. These captures may be in PCAP 
format for download and further analysis on products like TCPDUMP or Ethereal.

We modified the following screen: Wizards > Packet Capture Wizard > Capture Wizard.
