Chapter 8 Configuring Interfaces
Default MAC Addresses
By default, the physical interface uses the burned-in MAC address, and all subinterfaces of a physical
interface use the same burned-in MAC address.
Starting Interface Configuration (ASA 5510 and Higher)
This section includes tasks for starting your interface configuration for the ASA 5510 and higher.
For multiple context mode, complete all tasks in this section in the system execution space. If you are

Task Flow for Starting Interface Configuration
To start configuring interfaces, perform the following steps:
(Multiple context mode) Complete all tasks in this section in the system execution space. If you are not
Step 1
already in the System configuration mode, in the Configuration > Device List pane, double-click System
under the active device IP address.
Enable the physical interface, and optionally change Ethernet parameters. See the
Step 2
Interface and Configuring Ethernet Parameters" section on page
Physical interfaces are disabled by default.
(Optional) Configure redundant interface pairs. See the
Step 3
page
A logical redundant interface pairs an active and a standby physical interface. When the active interface
fails, the standby interface becomes active and starts passing traffic.
(Optional) Configure VLAN subinterfaces. See the
Step 4
Trunking" section on page
Step 5 (Multiple context mode only) Assign interfaces to contexts and automatically assign unique MAC
addresses to context interfaces. See
MAC Addresses (Multiple Context Mode)" section on page
