The original running configuration is savedas old_running.cfg (in the root directory of the internal Flash memory).WARNING: This command will change the behavior of the deviceWARNING: This command will initiate a Reboot 3 4. ASA Appliance converts the current runningconfiguration into two files: a new startup configuration that comprises the systemconfiguration, and admin.cfg that comprises the admin context (stored in the rootdirectory of the internal Flash memory). As Ive already stated, ASA appliance must be in multiple contextmode for creating Security contexts.!Verify ASA Operating mode.asa # show modeSecurity context mode: single! enable multiple mode, for switching to this Mode, restart is required.asa(config)#mode multipleThen the following output is displayed.

Equipment Used in this LABASA 5520 Cisco Adaptive Security Appliance Software Version 8.0(3)Catalyst 2960 LAN Lite IOS.Before starting configuration lets check if it works in Single context mode or multiplecontext mode. In the scenario in ourtopology below, we have one ASA appliance and lets create two contexts for twocustomers and one admin context for ASA appliance management.Physical Topology Diagram: 1Ģ. If you need to provide Threat Detection.Now lets consider an example of how Contexts are configured. If you need to support multicast routing. With multiple context mode, you canuse only static routes.

If you need to use dynamic routing protocols. If youd like to reduce hardware requirements by combining the functionality ofmultiple firewalls into one.When should you not use multiple security contexts? If you need to provide VPN services such as remote access or site-to-site VPNtunnels. If you need to provide different security policies for various departments, users, orvendors and need to create a separate context for each one. Keep in mind that withactive/active failover, you should not use more than half of the available bandwidth.If you are an ISP and need to offer a different security context for each customer. Lets make a little discussion when multiple context mode isadvisable and when it is not.When would you want to use multiple security contexts?If you want to use the active/active failover feature. In this mode somefeatures are not available, like Dynamic Routing, IPSEC and SSL VPN, Multicast andThreat Detection. For enabling the creation of virtual contextson the ASA appliance, we must switch to Multiple Context mode. The exception is theAdmin Context, from which the whole ASA appliance (physical ASA) is managed andalso is used to create the other Contexts. one context iscompletely isolated and does not depend on other contexts.

By default, all models support 2 security contexts without a licenseupgrade (except the Cisco ASA 5510 which requires the security plus license).Each Context has its own configuration file and security policy, i.e. Virtual ASA is also known as Security Context.All Cisco firewall models (except ASA 5505) support multiple security contexts (i.evirtual firewalls). Now we willtalk about Cisco ASA virtualization, which means multiple virtual firewalls on thesame physical ASA chassis. 1.How to Configure Cisco ASA Virtual Firewall?Device virtualization is one of the most popular topics in IT industry today and Ciscohas been supporting this concept in the majority of its network devices.
