I recently loaded 8.3(1) on the ASA5580 on a out of the box ASA. The only thing I changed in the config is the IP address for the interface and the location of the asdm command. I also deleted the old IOS from the flash. After I reload the box I notice the following changed. I wonder is this normal? If not, how to correct them?
1. During reload I see this. In the config file I don't have that in line 4 running config so how this get into startup config. The file 8_1_2_0_startup_cfg.sav create itself in the flash.
*** Output from config line 4, "ASA Version 8.1(2) "
2. In show version I see perpetual in every line. Is this normal?
Licensed features for this platform:
Maximum Physical Interfaces: Unlimitedperpetual
Maximum VLANs: 250perpetual
Inside Hosts: Unlimitedperpetual
3. In the show flash there are new file created. Is that mean ASA see some errors?
When you upgrade from previous version of 8.2 and earlier, the migration upgrade to version 8.3.1 will save a copy of the old ASA configuration because there has been a total change in the NAT translation from version 8.3.1 onwards. NAT from version 8.3.1 is devided into auto NAT and manual NAT. Licensing in ASA version 8.3.1 also changes.
Here is the release notes for 8.3.1 new change for your reference:
