Starting ASA 5505 Interface Configuration
Detailed Steps
What to Do Next
Configure the switch ports. See the
“Configuring and Enabling Switch Ports as Access Ports” section on
“Configuring and Enabling Switch Ports as Trunk Ports” section on page 1-9
.
Configuring and Enabling Switch Ports as Access Ports
By default (with no configuration), all switch ports are shut down, and assigned to VLAN 1. To assign
a switch port to a single VLAN, configure it as an access port. To create a trunk port to carry multiple
VLANs, see the
“Configuring and Enabling Switch Ports as Trunk Ports” section on page 1-9
. If you
have a factory default configuration, see the
“ASA 5505 Default Configuration” section on page 1-19
check if you want to change the default interface settings according to this procedure.
For more information about ASA 5505 interfaces, see the
“Information About ASA 5505 Interfaces”
Command
Purpose
Step 1
interface
vlan
number
Example:
hostname(config)# interface vlan 100
Adds a VLAN interface, where the
number
is between 1 and 4090.
To remove this VLAN interface and all associated configuration,
enter the
no interface vlan
command. Because this interface also
includes the interface name configuration, and the name is used in
other commands, those commands are also removed.
Step 2
(Optional for the Base license)
no forward interface vlan
number
Example:
hostname(config-if)# no forward interface
vlan 101
Allows this interface to be the third VLAN by limiting it from
initiating contact to one other VLAN.
The
number
specifies the VLAN ID to which this VLAN interface
cannot initiate traffic.
With the Base license, you can only configure a third VLAN if
you use this command to limit it.
For example, you have one VLAN assigned to the outside for
Internet access, one VLAN assigned to an inside business
network, and a third VLAN assigned to your home network. The
home network does not need to access the business network, so
you can use the
no forward interface
command on the home
VLAN; the business network can access the home network, but
the home network cannot access the business network.
If you already have two VLAN interfaces configured with a
nameif
command, be sure to enter the
no forward interface
command before the
nameif
command on the third interface; the
ASA does not allow three fully functioning VLAN interfaces with
the Base license on the ASA 5505.
Note
If you upgrade to the Security Plus license, you can
remove this command and achieve full functionality for
this interface. If you leave this command in place, this
interface continues to be limited even after upgrading.
