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.
• You can only configure context interfaces that you already assigned to the context in the system
configuration using the allocate-interface command.

1. For an interface to count against the VLAN limit, you must assign a VLAN to it. For example:
interface gigabitethernet 0/0.100
vlan 100
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
