Task Flow for Completing Interface Configuration
Step1 Set up your interfaces depending on your model:
ASA 5510 and higher—Chapter6, “Starting Interface C onfiguration (ASA5510 and Highe r).”
ASA 5505—Chapter7, “Starting Interface Configuration (ASA 5505).”
Step2 (Multiple context mode) Allocate interfaces to the context according to the “Configuring Multiple
Contexts” section on page5-14.
Step3 (Multiple context mode) Enter the changeto context name command to change to the context you want
to configure. Configure general interface parameters, including the interface name, security level, and
IPv4 address. See the “Configuring General Interface Parameters” section on page 8-6.
Step4 (Optional) Configure the MAC address and the MTU. See the “Configuring the MAC Address and
MTU” section on page 8-9.
Step5 (Optional) Configure IPv6 addressing. See the “Configuring IPv6 Addressing” section on page 8-11.
Step6 (Optional) Allow same security level communication, either by allowing communication between two
interfaces or by allowing traffic to enter and exit the same interface. See the “Allowing Same Security
Level Communication” section on page 8-15.
Configuring General Interface Parameters
This procedure describes how to set the name, security level, IPv4 address and other options.
For the ASA 5510 and higher, you must configure interface parameters for the following interface types:
Physical interfaces
VLAN subinterfaces
Redundant interfaces
EtherChannel interfaces
For the ASA 5505, you must configure interface parameters for the following interface types:
VLAN interfaces
Guidelines and Limitations
For the ASA 5550, for maximum throughput, be sure to balance your traffic over the two interface
slots; for example, assign the inside interface to slot 1 and the outside interface to slot 0.
