ASA LAN failover Problem

You may refer to the steps in the link below:

I hope this helps!

If you are going for factory reset use the following commands

asa>enable
asa#write erase
asa#reload

Dont save the configuration when it prompts for it.

if you want to restore the configuration from the backup

1. You need to have a TFTP server
2. Locate the config file on your TFTP server
3. TFTP server should be reachable from ASA

then

asa#copy tftp flash

give the tftp server ip address
give the configuration file name (as exactly on the TFTP server)

reload

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.

Hi the documentation lists it in detail if you donot have the docs then access the same on Cisco web site it is free

A conflict in the IP address, resolve it

Voila un link pour un bon simulateur:

PPPoE is not supported when failover is configured on the security appliance, or in multiple context or transparent mode. PPPoE is only supported in single, routed mode, without failover.

I had this same issue on my ASA 5520.

1. Copy the config and IOS image to a tftp server.
2. Format flash (disk0)
3. set rommon server, ip addy, and file settings.
4. tftpdnld
5. Once the system has booted to the image copy the asa image file, asdm image file, and config to flash
6. configure asdm image default location and reload
