Cisco ASA failover active/standby

[mohamedjasren]

Hi all,

need to ask about implemanting Cisco ASA failover Active/Standby

my question are

1) need to run ASDM on both active/standby same version?? lets say 6.4.5

2) failover link need to used crossover cable?

3) IPS ver need to be same on active/standby

1) need to run ASDM on both active/standby same version?? lets say 6.4.5

Yes, this is because the configuration of the Active ASA is copied to the standby ASA.  In the configuration are the settings of which ASDM image to use, so if you have a different ASDM image installed on the standby than the one that is defined in the configuration, the standby ASA will not know where to launch the ASDM from.

2) failover link need to used crossover cable?

No, The default auto negotiation on ASAs use auto MDI/MDIX

3) IPS ver need to be same on active/standby

Yes and no.  IPS settings do not replicate so you need to manually configure each IPS.  Ofcourse it is recommended to use the same on both.
