What is ASA multiple context mode?
Cisco ASA supports multiple firewall contexts, also called firewall multimode or multi-context mode. Multi-context mode divides a single ASA into multiple virtual devices, also known as security contexts. Each context operates a single device, independently from other security contexts.
How many context can be created in ASA?
In this example, the ASA can have up to five customer contexts.
Which features are not supported in multiple context mode?
While features like routing tables, firewall features, IPS, and management being supported in multiple context mode, some features are not supported like VPN and dynamic routing protocols.
Does Cisco ASA support VPN is multi context mode if yes then which release onwards is the feature supported?
I understand from version 9.2 onwards ASA supports IPSec and Dynamic routing protocol in Multi- context implementation.

Multiple Context Mode divides Adaptive Security Appliance ( ASA ) into multiple logical devices, known as security contexts. Each security context acts like one device and operates independent from other security contexts.
How do you upgrade ASA in multiple context?
Upgrade an Active/Standby Failover Pair.
- Step 2 Copy the ASA software to the active unit flash memory:
- Step 3 Copy the software to the standby unit; be sure to specify the same path as for the active unit:
- Step 4 Copy the ASDM image to the active unit flash memory:
How do you create a new context in Asa?

- Allocate the interfaces.

- Configure a customer context.
- Manage the security contexts (optional).
How do I get to system context in Asa?
To access the system execution space, you can do either of the following:
