Re: interpret failover command on my asa

Hello,

Get  used to referencing these links bellow ,  look at command line syntax for each command .   Read the " Usage Guidelines "  that explains each command usage.


Command reference failover
http://www.cisco.com/en/US/docs/security/asa/asa82/command/reference/ef.html


This is how failover works,  read this link  - Active/Standby   failover  overview
