Chapter 1 Completing Interface Configuration (Routed Mode)
Guidelines and Limitations
Guidelines and Limitations
This section includes the guidelines and limitations for this feature.
Context Mode Guidelines
• For the ASA 5510 and higher in multiple context mode, configure the physical interfaces in the
system execution space according to Chapter 1, “Starting Interface Configuration
(ASA 5510 and Higher).” Then, configure the logical interface parameters in the context execution
space according to this chapter. For the ASASM in multiple context mode, configure switch ports
and VLANs on the switch, and then assign VLANs to the ASASM according to Chapter 1,
“Configuring the Switch for Use with the ASA Services Module.”
The ASA 5505 does not support multiple context mode.
• In multiple context mode, you can only configure context interfaces that you already assigned to the
context in the system configuration according to the “Configuring Multiple Contexts” section on
page 1-15.
• PPPoE is not supported in multiple context mode.
Firewall Mode Guidelines
Supported in routed firewall mode. For transparent mode, see Chapter 1, “Completing Interface
Configuration (Transparent Mode).”
Failover Guidelines
Do not finish configuring failover interfaces with the procedures in this chapter. See the “Configuring
Active/Standby Failover” section on page 1-7 or the “Configuring Active/Active Failover” section on
page 1-9 to configure the failover and state links. In multiple context mode, failover interfaces are
configured in the system configuration.
IPv6 Guidelines
Supports IPv6.
2. The maximum number of combined interfaces; for example, VLANs, physical, redundant, bridge group, and EtherChannel interfaces. Every interface
command defined in the configuration counts against this limit. For example, both of the following interfaces count even if the GigabitEthernet 0/0
interface is defined as part of port-channel 1:
interface gigabitethernet 0/0
and
interface port-channel 1
