cisco asa is multi software device

Cisco ASA Device Package software supports only the version of APIC that it is ASA multi-context feature with overlapping mgmt IPs. You can partition a single security appliance into multiple virtual devices, known as security contexts. Each context is an independent device. You can partition a single ASA into multiple virtual devices, known as security contexts. Each context acts as an independent device, with its.

External Hardware. External Software. Cisco Nexus Cisco Catalyst with Sup 32, and GE. Cisco Catalyst X. What operating system is the ASA built on? Please refer to the Cisco ASA 9. Where can I find information on new features introduced in each software release?

This information is in the software release notes. The software can be downloaded from the Cisco Download Software page registered customers only. How can a customer find out about new software defects and software updates?

Where I can find comparisons of ASA models? It also supports mixed- route and transparent-mode multicontext configurations. Most important, with ASA Software:. This migration requires a redesign of the network infrastructure. What is the Cisco ASAv? The ASAv supports consistent, transparent security across physical, virtual, application-centric, and cloud environments.

Yes, ASAv is in full sync with physical appliance features, with the exception of multiple contexts, clustering, and EtherChannel. The policy rule is integrated into ASA policy and its stateful firewalling. With the Controlled Introduction 9. The ASAv software does not do anything special to drop traffic that exceeds the threshold. If the vCPU is running close to close to capacity, incremental traffic will see a drop in speed.

What hypervisors does ASAv support? Following is the list of hypervisors and tentative timelines for support:. What are the system requirements to run ASAv? What are the different types of licenses that exist for an ASA? The ASA supports three basic types of licenses:.

What is the format of an ASA X license? The ASA X license consists of a series of five hexadecimal strings, which need to be entered with the activation-key command-line interface or an ASDM license. It will ship preinstalled when ordered with the appliance. A license is exclusively tied to the serial number of the ASA appliance.

It cannot be transferred. Do I need a license for a standby appliance? Failover units or standby appliances do not require the same license on each unit. What are the licensing requirements for ASA clustering? Please see Table 1. All other models No support. How do licenses combine for failover pairs or cluster units?

For failover pairs or ASA clusters, the licenses on each unit are combined into a single running Cluster license. If you buy separate licenses for each unit, then the combined license uses the following rules:. What happens if I enter a wrong license key? License check happens at runtime. A wrong license key will be rejected and the existing license will remain in effect. A license key change does not affect the network traffic flowing through the ASA appliance.

Configuration removal and the formatting of internal flash will not remove the license key. How do I remove the license key from an appliance? This command is applicable only to time-based licenses. ASA licenses fall into three categories. Perpetual licenses are always in effect and are tied to the serial number of the appliance.

Count-based licenses can float between active and standby appliances, and time-based licenses are not dependent on the ASA clock settings. Is there a license to enable the Botnet Traffic Filter? Yes, an annual license is required to enable this feature. Designed for mission-critical data centers that require exceptional flexibility and security, the new Cisco ASA X Adaptive Security Appliance delivers superior technology that spans multiple platforms and deployment scenarios.

The Cisco ASA X scales to the highest VPN session counts, throughput, and connection speed and capacity to meet the growing needs of today's most dynamic organizations, all in a compact 2-RU footprint. Offering protocol-agnostic client and clientless access for a broad spectrum of desktop and mobile platforms, the Cisco ASA X delivers versatile, always-on remote access integrated with IPS and web security for highly secure mobility and enhanced productivity.

What are the rails that come with an ASA X? ASA X has two types of rails: An internal rail is attached to the chassis at the time of manufacturing this is not orderable except with the chassis. What is the maximum performance of ASA appliances? What features affect performance on ASA Software?

All computation-intensive features such as deep packet inspections and logging will have a direct impact on the performance of ASA Software. For detailed information, watch the presentation. It is subject to change. Does performance vary from one software release to another? New features result in a minor variance in performance from one software release to another across all ASA platforms. What indicates that an ASA X appliance is over its maximum capacity?

Prolonged high CPU use anything over 90 percent , less than 10 percent of available memory, and interface packet drops due to high numbers of packets per second are all signs of appliance reaching its capacity limits. Is there a third-party performance report for ASA X appliances?

Is it possible to set artificial limits on certain resources? Resource management is available in the multicontext mode. More details are provided in the configuration guide under the subheading Information for Resource Management. Average latency on the new appliances varies between 15 to 30 microseconds.

These are early results. How does the latency compare to that of the ASA series of appliances? For example, average latency on the ASA is close to 70 microseconds. ASA X exhibits latencies closer to 40 microseconds. Where I can find information about the different ASA models in terms of the following? Please see the following documents. Feature enhancements require additional RAM. What is the port density number of supported ports for an ASA X?

The base slot slot 0 should have a firewall SSP. The number of supported ports varies depending on the model see Table 4. The traffic hits one context where it is allowed, then hits a second context where the traffic is dropped. Any idea how to improve the performance? In cascaded contexts, 75, pps of small packets becomes , pps. Much of the performance depends on how this traffic arrives at the ASA the number of flows, the uniformity, and so on.

The Botnet Traffic Filter monitors the network across all ports and protocols for rogue activity. It detects infected internal endpoints and bots sending command-and-control traffic back to a host on the Internet. The command-and-control hosts receiving the information are identified using the Botnet Traffic Filter database.

With updates from Cisco Security Intelligence Operations SIO , this feature can provide fast and accurate protection against botnet threats. The Botnet Traffic Filter is complementary to existing Cisco security solutions. Cisco Content Security and IPS solutions protect endpoints and servers by identifying and blocking malware. The Botnet Traffic Filter assists in identifying endpoints that have already been infected or have bypassed existing endpoint prevention solutions.

No, the databases are not the same. What reports are available with the Botnet Traffic Filter? The Botnet Traffic Filter offers reports on top infected hosts, top botnet domains or "sites" , and top malware ports. What are the advantages of cloud web security being integrated with the firewall?

However, in contrast to all-in-one offerings, which suffer significant performance degradation when web security services are enabled, there is little to no impact on ASA performance because the content scanning is offloaded to the Cisco web security cloud.

Administrators can choose to perform deep content scanning on a subset of traffic, based on network address, Microsoft Active Directory user or group name, or hosts residing inside a specific security context. The outbound traffic can be classified according to user name, user group, source, or destination. The destination aspect can be further classified into three broad categories:.

How does integrated Cisco Cloud Web Security compare with web security functions that are offered on-box from other firewall vendors? The key challenge with all-in-one approaches to security is that all security functions firewall, network access control, web, antivirus, VPN, and so on compete for fixed computing resources.

As a result, performance can drop significantly as more services are deployed. My deployment is not yet ready for identity enablement. Traffic can be redirected to Cisco Cloud Web Security based on 5-tuples. Or you can use a cut-through proxy or local database users on the Cisco ASHowever, either of these methods will disable user-level and group-level reporting. When the ASA is configured for the multicontext mode, managed security providers can deploy Cisco Cloud Web Security on a per-context basis.

Cisco Cloud Web Security classifications require the following information:. Up to 10 percent of the employees in my organization are remote. The AnyConnect client performs a split tunneling of web and VPN traffic to eliminate the need to backhaul Internet traffic to company headquarters, thereby supporting complex remote access use cases.

How can I enforce Web 2. This entire process is transparent to the end user. How does this integration achieve high availability? In exceptional circumstances, if both Cisco Cloud Web Security towers are unavailable because Internet connectivity is lost, for example , the ASA can be configured to either fail-open or fail-close. Previous releases of ASDM are not supported. Can management access to your solution be restricted by an access control list or other method?

Does your solution support certificate-based authentication for management access? There are several options, depending on your specific configuration. Previous releases do not support these next-generation firewalls. Do you provide an enterprise management tool with the capability to manage multiple instances of your solution?

Yes, the Cisco Content Switching Module delivers this capability. Can your enterprise management tool access the local logs of an instance of your solution? It does not access local logs from the individual devices but receives events from them and correlates them. This feature is particularly useful for connection logging in high -performance environments. On an ASA, can you take a packet capture and export the file to the administrator context? Basically, can you move files between contexts?

Or do they have to move the files through the network? In my network, systems outside the firewall need to talk to systems inside the firewall, and the firewall itself needs to talk to the same systems, but needs to do it through the management interface instead of the inside interface. How is this generally handled when the management interface and the inside interface are in the same routing table? When you configure the interface as "management only," it will not accept transit traffic and will be dedicated only to traffic "to the box.

What is ASA routed mode? In the routed mode, the ASA is considered to be a router hop in the network. The routed mode supports many interfaces. Each interface is on a different subnet. You can share interfaces between contexts. What is the ASA firewall transparent mode? Traditionally, a firewall is a routed hop and acts as a default gateway for hosts that connect to one of its screened subnets. A transparent firewall, on the other hand, is a Layer 2 firewall that acts like a "bump in the wire," or a "stealth firewall," and is not seen as a router hop to connected devices.

What are the benefits of deploying a firewall in transparent mode? The security appliance connects the same network on its inside and outside ports in transparent mode. Following are some of the benefits:. What features are not supported in transparent mode? These features are not supported in transparent mode:. An ASA operating in transparent mode does not rely on the ARP table for transit communication; it is only for to-the-box and from-the-box traffic.

How does interface monitoring work when the failover link is up in transparent mode? Does ASA act as a traditional load balancer? Are there any best-practice documents for ASA deployment in the data center? Please see the following documents:. There is no hard-coded limit on the number of elements access control entries in an ACL, which is bound only by memory. However maximum performance may decrease typically by 10 to 15 percent as you reach or exceed the recommended maximum number of ACEs.

See Table 3 above for throughputs. What are the limits for policy maps, class maps, and classes in ASA? Here are the limits:. Does ASA offer traffic-policing capabilities? If yes, how is this done? ASA does have traffic-policing capabilities to restrict the bandwidth of an inbound flow, but if you are planning on doing this as a distributed denial-of-service DDoS defense, then do not expect fantastic results, because the DDoS could fill up the pipe with traffic before the ASA drops the offending packets.

If a given source or destination flow is configured for TCP state bypass, and the ACL on inside interface allows it, do I need to create an ACL for return traffic on the outside interface? Most Cisco devices can transport this security group information with the user's traffic. The administrator can allow or block access for a user to corporate resources based on certain attributes. Can your firewall solution perform protocol inspection for standards compliance and to facilitate the opening of dynamic ports for example, H.

If so, please list them. ASA capability helps customers prepare for migrating to IPv6 by delivering critical v4 to v6 translation. ASA delivers IPv6 remote access connections with less than a 15 percent performance impact compared with IPv4 traffic.

In contrast, other offerings experience an average of 80 percent degradation in performance when transitioning from an IPv4 to an IPv6 traffic pattern. Can the ASA X be used simultaneously as a firewall and a remote access appliance? The ASA X Series has been designed to run multiple simultaneous services without sacrificing performance. How does ASA Software provide highly secure remote access? IPv6 clientless support is also provided. While most other offerings experience an average of 80 percent degradation in performance when transitioning from an IPv4 to an IPv6 traffic pattern, ASA Software supports IPv6 remote access connections with less than a 15 percent performance impact.

ASA Software also provides comprehensive next-generation encryption capability, which includes Suite B cryptography standards for remote access and site -to-site connections using an IPsec tunnel. ASA 9. The clientless VPN enhancements include:. What do the clientless VPN enhancements bring to users? Benefits of the clientless VPN enhancements include the following:.

End users can access the Citrix Xen infrastructure through the clientless portal. Does the ASA X offer a separate hardware cryptographic module like other offerings in the market? Hardware cryptographic acceleration is already built into the ASA X, so there is no need for an optional hardware cryptographic module. Does ASA 9. Is next-generation encryption available on all ASA platforms?

It is partially supported on the ASA , , , , and models. Cisco AnyConnect 3. This capability helps deliver confidentiality and integrity with a smaller key size with NSA-approved Suite B encryption specifications. How many members are allowed within one failover group for ASA? As soon as the failover command is executed, there is a to second loss of connectivity through the firewall.

Is this expected? This is expected behavior. Upon enabling failover, the unit will wait for 45 seconds before going active in case another active unit already exists. For a few seconds, the two blades will see different sessions. Log in to Save Content. Available Languages. Download Options. Updated: November 2, This version contains the following subset of features of the original version: Interface Dynamic routing Static routing.

Note To upgrade from an older to a newer version, you do not need to remove the previous software package if your APIC release has the fix for CSCuv Table 1. CSCvk Support port-channel span-cluster. Table 2. CSCvj Cannot assign bridge-group to interface. The ASAv does not support multiple context mode. Use this workaround for caveat CSCvd Symptom: When cluster interfaces are changed under lif configuration for a deployed graph in bridge mode, the new interface might not get updated correctly on the ASA.

Conditions: When changes are made to the ASA device cluster interface configuration. Use this workaround for caveat CSCvd Symptom: When a second or subsequent graph is deployed on a new set of cluster interfaces in an ASA in bridged mode, the user might see cluster interfaces not configured under the correct bridge-group. Examples of such commands include: access-list object network object service object-group network object-group service.

Cisco asa is multi software device Cisco ASA X. For management traffic destined for an interface, the interface IP address is used for classification. What hypervisors does ASAv support? Telnet sessions—5 sessions. For transparent firewalls, you must use unique interfaces. Total The total amount of the resource that is allocated across all contexts. In my network, systems outside the firewall need to talk to systems inside the firewall, and the firewall itself needs to talk to the same systems, but needs to do it through the management interface instead of the inside interface.
