Cisco ASA Series CLI Configuration Guide
Chapter 1 Completing Interface Configuration (Transparent Mode)
Default Settings
VLAN ID Guidelines for the ASASM
You can add any VLAN ID to the configuration, but only VLANs that are assigned to the ASA by the
switch can pass traffic. To view all VLANs assigned to the ASA, use the
show vlan
command.
If you add an interface for a VLAN that is not yet assigned to the ASA by the switch, the interface will
be in the down state. When you assign the VLAN to the ASA, the interface changes to an up state. See
the
show interface
command for more information about interface states.
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
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.
Default State of Interfaces for the ASASM
•
In single mode or in the system execution space, VLAN interfaces are enabled by default.
•
In multiple context mode, all allocated interfaces are enabled by default, no matter what the state of
the interface is in the system execution space. However, for traffic to pass through the interface, the
interface also has to be enabled in the system execution space. If you shut down an interface in the
system execution space, then that interface is down in all contexts that share it.
Jumbo Frame Support
By default, the ASASM supports jumbo frames. Just configure the MTU for the desired packet size
according to the
“Configuring the MAC Address and MTU” section on page 1-13
.
