ASDM Version: 7.1(2)
ASA Version: 5.1(2)
I have three questions that I have not been able to get solid answers for and I was hoping the experienced here could offer help:
1. What is the safest way to upgrade an ASA 5510 to 7.2. For example, save running config to file, upgrade/boot new image, copy config back? Please provide proven procedure because I have not seen any exact procedure in any of the CISCO books that I have. What are the gotchas?
2. When Monitoring the Properties tab (after Clicking Monitoring->Properties in ASDM GUI) over a VPN, at the bottom of the screen it says "contacting device for latest monitoring data". However, the progress bar never gets above 72% and then errors out with a warning about not getting a response from ASDM in 60 seconds. Why is this?
3. None of the books I have discuss the configuration for the dns keyword in the config file, for example, in my config I have:
dns dmain-lookup inside
dns server-group DefaultDNS
What is the ASA device actually using this information for? Clients are not querying the router for DNS information, so how is this used?
Any help with any of these questions would be appreciated.
For your first question, the following document link will guide you
For 2nd question --- probably, the error is due to timeout issues.
For 3rd question, command refernce will provide you the idea.
