Cisco ASA 5500 Series Configuration Guide using ASDM
Chapter 15 Completing Interface Configuration (TransparentMode, 8.4 and Later)
Default Settings
Failover Guidelines
Do not finish configuring failover interfaces with the procedures in this chapter. See the “Configuring
Active/Standby Failover” section on page 66-7 or the “Configuring Active/Active Failover” section on
page 67-8 to configure the failover and state links. In multiple context mode, failover interfaces are
configured in the system configuration.
IPv6 Guidelines
• Supports IPv6.
• No support for IPv6 anycast addresses in transparent mode.
Default Settings
This section lists default settings for interfaces if you do not have a factory default configuration. For
information about the factory default configurations, see the “Factory Default Configurations” section
on page 2-10.
Default Security Level
The default security level is 0. If you name an interface “inside” and you do not set the security level
explicitly, then the ASA sets the security level to 100.
Note If you change the security level of an interface, and you do not want to wait for existing connections to
time out before the new security information is used, you can clear the connections using the
clear local-host command.
