Console error when i power on the asa 5510,the four lights are getting up suddenly ( power, active, status,vpn). but i cant get console

Hi,

Its simple, you have reboot with console connect, get into to ROM mode and change configuration registry so it will not load the saved configuration. Please refer Resetting the passwords on Cisco ASA 5510 Binary Royale Ltd for the step by step process

this has been nicely explained here:

http://www.computerfreetips.com/Cisco_router_tips/ASA-VPN-tunnel.html

Here is the manual:

connect your laptop to the asa5510 using a cross over cable

can you try lower encryption levels on each device and see if that helps? sometimes it is neccesary between Cisco and other devices.

Yes. The firewall will restart. Just be sure to save your running config to memory before turning off. For that you must issue the command: write memory.

Best Regards,

are you using hyper terminal? if you are using another program, switch to hyperterminal and reboot (if possible after saving config) with the cable connected. See if anything at all comes up on the screen.

You can only do active/active if you're using multiple contexts. Active/active can give you some extra performance for your $ since you can pass traffic through both ASAs. Compare this to active/standby where the standby unit passes no traffic.

If you're pushing the 5510's to 80% capacity each in active/active mode, then you have one fail, now the one single ASA is oversubscribed. The oversubscription could cause connectivity issues that defeat the purpose of failover in the first place.

In the spirit of reliability go with active/standby. Seeing that you have two active core switches that would be pushing all of their traffic through a single 5510 in this case....it may be too much active/active may be the better solution.

A conflict in the IP address, resolve it

Obtain the serial number for your security appliance by entering the following command:
hostname# show activation-key
Step 2
Access one of the following URLs.
•
Use the following website if you are a registered user of Cisco.com:
http://www.cisco.com/go/license
•
Use the following website if you are not a registered user of Cisco.com:
http://www.cisco.com/go/license/public
Step 3
Enter the following information, when prompted:
•
Product Authorization Key (if you have multiple keys, enter one of the keys first. You have to enter
each key as a separate process.)
•
The serial number of your security appliance
•
Your email address
An activation key is automatically generated and sent to the email address that you provide. This key
includes all features you have registered so far for permanent licenses. For VPN Flex licenses, each
license has a separate activation key.
Step 4
If you have additional Product Authorization Keys, repeat Step 3 for each Product Authorization Key.
After you enter all of the Product Authorization Keys, the final activation key provided includes all of
the permanent features you registered
