To change the active interface, enter the following command:. This section describes how to create an EtherChannel port-channel interface, assign interfaces to the EtherChannel, and customize the EtherChannel.

This section describes how to create an EtherChannel port-channel interface and assign interfaces to the EtherChannel. By default, port-channel interfaces are enabled. This first interface in the channel group determines the type and speed for all other interfaces in the group. In transparent mode, if you create a channel group with multiple Management interfaces, then you can use this EtherChannel as the management-only interface. If the port-channel interface for this channel ID does not yet exist in the configuration, one will be added:.

We recommend using active mode. Sets the priority for a physical interface in the channel group between 1 and The default is The higher the number, the lower the priority. The ASA uses this setting to decide which interfaces are active and which are standby if you assign more interfaces than can be used. The lowest interface ID is the highest priority. If you want to prioritize an interface to be active even though it has a higher interface ID, then set this command to have a lower value.

If the device at the other end of the EtherChannel has conflicting port priorities, the system priority is used to determine which port priorities to use. Repeat steps 1 through 5 for each interface you want to add to the channel group. Each interface in the channel group must be the same type and speed.

Half duplex is not supported. If you add an interface that does not match, it will be placed in a suspended state. This section describes how to set the maximum number of interfaces in the EtherChannel, the minimum number of operating interfaces for the EtherChannel to be active, the load balancing algorithm, and other optional parameters.

Specifies the port-channel interface. This interface was created automatically when you added an interface to the channel group. If you have not yet added an interface, then this command creates the port-channel interface. Note You need to add at least one member interface to the port-channel interface before you can configure logical parameters for it such as a name.

Specifies the maximum number of active interfaces allowed in the channel group, between 1 and 8. The default is 8. Specifies the minimum number of active interfaces required for the port-channel interface to become active, between 1 and 8. The default is 1. If the active interfaces in the channel group falls below this value, then the port-channel interface goes down, and could trigger a device-level failover. Configures the load-balancing algorithm. By default, the ASA balances the packet load on interfaces according to the source and destination IP address src-dst-ip of the packet.

If you want to change the properties on which the packet is categorized, use this command. For example, if your traffic is biased heavily towards the same source and destination IP addresses, then the traffic assignment to interfaces in the EtherChannel will be unbalanced. Changing to a different algorithm can result in more evenly distributed traffic.

Sets the LACP system priority, from 1 to This command is global for the ASA. You can set the Ethernet properties for the port-channel interface to override the properties set on the individual interfaces.

This method provides a shortcut to set these parameters because these parameters must match for all interfaces in the channel group. Subinterfaces let you divide a physical, redundant, or EtherChannel interface into multiple logical interfaces that are tagged with different VL AN IDs.

An interface with one or more VLAN subinterfaces is automat ically configured as an Because VLANs allow you to keep traffic separate on a given physical interface, you can increase the number of interfaces available to your network without adding additional physical interfaces or ASAs. This feature is particularly useful in multiple context mode so that you can assign unique interfaces to each context. Specifies the new subinterface.

The redundant number argument is the redundant interface ID, such as redundant 1. The port-channel number argument is the EtherChannel interface ID, such as port-channel 1. The subinterface ID is an integer between 1 and Specifies the VLAN for the subinterface.

You cannot assign a VLAN to the physical interface. A jumbo frame is an Ethernet packet larger than the standard maximum of bytes including Layer 2 header and FCS , up to bytes. You can enable support for jumbo frames for all interfaces by increasing the amount of memory to process Ethernet frames.

Assigning more memory for jumbo frames might limit the maximum use of other features, such as access lists. Enables jumbo frame support for the ASA and X. To disable jumbo frames, use the no form of this command. The following example enables jumbo frame reservation, saves the configuration, and reloads the ASA:.

To monitor interfaces, enter one of the following commands:. For EtherChannel, displays EtherChannel information in a detailed and one-line summary form. This command also displays the port and port-channel information.

For EtherChannel, displays port-channel load-balance information along with the hash result and member interface selected for a given set of parameters. The following example configures parameters for the physical interface in single mode:. The following example configures parameters for a subinterface in single mode:. The following example configures three interfaces as part of an EtherChannel.

Assign interfaces to contexts and automatically assign unique MAC addresses to context interfaces. Table lists the release history for this feature. Table Feature History for Interfaces. Increased interfaces for the Base license on the ASA For the Base license on the ASA , the maximum number of interfaces was increased from 3 plus a management interface to unlimited interfaces.

Use the speed command to change the speed on the interface and use the show interface command to see what speed is currently configured for each interface.

The Cisco ASA supports jumbo frames. We introduced the following command: jumbo-frame reservation. You can now enable pause XOFF frames for flow control. We introduced the following command: flowcontrol. We modified the following command: flowcontrol. You can configure up to 48 We introduced the following commands: channel-group , lacp port-priority , interface port-channel , lacp max-bundle , port-channel min-bundle , port-channel load-balance , lacp system-priority , clear lacp counters , show lacp , show port-channel.

Updated: November 14, Using Any Interface for Management-Only Traffic You can use any interface as a dedicated management-only interface by configuring it for management traffic, including an EtherChannel interface see the management-only command.

Management Interface for Transparent Mode In transparent firewall mode, in addition to the maximum allowed through-traffic interfaces, you can also use the Management interface either the physical interface, a subinterface if supported for your model , or an EtherChannel interface comprised of Management interfaces if you have multiple Management interfaces as a separate management interface.

However, physical characteristics such as enabling the interface are configured on the ASA. Redundant Interfaces A logical redundant interface consists of a pair of physical interfaces: an active and a standby interface.

EtherChannels An You can configure up to 48 EtherChannels. An active EtherChannel can establish connectivity with either an active or a passive EtherChannel. You should use the active mode unless you need to minimize the amount of LACP traffic. A passive EtherChannel can only establish connectivity with an active EtherChannel.

Interfaces of all types 2 : Base and Security Plus License: 4. Each bridge group can include up to four interfaces. For multiple context, transparent mode, each context must use different interfaces; you cannot share an interface across contexts. Failover Guidelines When you use a redundant or EtherChannel interface as a failover link, it must be pre-configured on both units in the failover pair; you cannot configure it on the primary unit and expect it to replicate to the secondary unit because the failover link itself is required for replication.

If you use a redundant or EtherChannel interface for the state link, no special configuration is required; the configuration can replicate from the primary unit as normal. You can monitor redundant or EtherChannel interfaces for failover using the monitor-interface command; be sure to reference the logical redundant interface name. When an active member interface fails over to a standby interface, this activity does not cause the redundant or EtherChannel interface to appear to be failed when being monitored for device-level failover.

Note: MD5 is the recommended configuration for ospf authentication,! The firewall data plane handles most of the traff i c that traverses the firewall.

Data plane protection can prevent attacks for both the firewall and devices to which the firewall sends traffic. Securing the control plane and management plane is essential, but all control plane and data plane traffic traverses through the data plane.

Because the data plane is responsible for processing and forwarding traffic, protecting the firewall data plane plays an important part in firewall hardening and security. Any activated firewall feature may affect data plane traffic, so it is important to keep the firewall software version updated to the latest stable code that meets business requirements.

It is also important to back up all firewall rulebase and configuration files regularly on a separate, accessible location. Backups can be used after a system failure and helps reduce total downtime.

The Adaptive Security Algorithm ensures the secure use of applications and services. Some applications require special handling in the Adaptive Security Algorithm firewall application inspection function. These applications embed IP addressing information in the user data packet or open secondary channels on dynamically assigned ports.

A host on one firewall interface can create any type of connection to a host on another interface of the same firewall as long as any required address translation can be made and relevant interface access lists permit it. When address translation methods are required and after they have been configured between pairs of firewall interfaces, the administrator must configure and apply access lists to the interfaces.

The steps required for placing an ACL on the firewall include configuring the ACL and binding it to a firewall interface. Any source and destination address specified in the ACL is relative to any address translation that occurs on the interface where the ACL is applied.

ACEs can classify packets by inspecting Layer 2 through Layer 4 headers for a number of parameters, including the following:. After an ACL has been properly configured, the administrator can apply it to an interface to filter traffic.

The security appliance can filter packets in both the inbound and outbound direction on an interface. An ACL must be applied to each lower-security interface so that specific inbound connections are permitted.

For information about security levels, refer to the Security Levels section of this document. Once the packet is allowed, the flow is created in the Adaptive Security Algorithm connection table, and all further packets in the flow are permitted based on the connection entry, bypassing the ACL check. You can use the show conn command to view the connection table. Note: ACLs are normally evaluated in the order in which they appear in the firewall configuration.

It is important to configure and use an ACL to limit the types of traffic in a specific direction. When traffic is permitted by an ACL, connections are allowed to pass; when traffic is denied, all corresponding packets are dropped at the firewall. In addition, when an xlate entry is created for a new connection and the interface ACLs permit the initial traffic, the return traffic specific to that connection is also permitted because the firewall has built the proper xlate and conn entries for it.

Therefore, ACL changes should be made when traffic through the firewall is low. This section lists some best practices to be followed for ACL configuration on firewalls. However, the list is not exhaustive and should serve as a guideline for firewall hardening. To control access to an interface, use the access-group command in interface configuration mode. This rule determines whether there any ACLs are defined that are not applied to an interface.

The permit ip any any command is not recommended. Allowing access to all destinations provides access to all the hosts inside the perimeter, including the firewall itself, and to all Internet hosts. Traffic should be carefully filtered to meet the organization's requirements. The permit icmp any any command is also not recommended. It is not secure to permit all ICMP traffic on firewalls, which would allow an attacker to exploit the network using ICMP attacks such as ping sweeps and ping floods.

Without stateful inspection, ICMP can be used to attack your network. The ICMP inspection engine ensures that there is only one response for each request, and that the sequence number is correct. The best practice is to use ACLs to limit as much traffic as possible. Administrators are advised to create exact matches of host and network addresses rather than using the generic keyword any in access lists.

Specifying the exact port numbers is recommended rather than opening all ports by not specifying anything in the ports field. Increased granularity increases security and also makes it easier to troubleshoot any malicious behavior. It is a best practice to have an explicit deny statement at the end and log all the denied packets. The log keyword at the end of the individual ACL entries shows the ACL number and whether the packet was permitted or denied in addition to port-specific information.

By default, logging message default severity level 4, warning is generated when a deny access list entry is matched with a traffic flow. One can also log the rate at which traffic flows match specific access list entries. This can be useful to gauge the volume of attacks or exploits that are occurring over time.

One can also set the logging severity level on a per-ACE basis if needed. Otherwise, severity level 6 is the default.

Note: Although all ACLs contain an implicit deny statement, Cisco recommends use of an explicit deny statement, for example, deny ip any any. On most platforms, such statements maintain a count of the number of denied packets. This count can be displayed using the show access-list command. The ability to configure security levels is a necessary firewall feature.

A security-level value from 0 through defines the trustworthiness of networks reachable through an interface. A value of 0 indicates the least trusted, and a value of indicates the most trusted.

Administrators are advised to correctly configure security levels for traffic traversal before ACLs are applied. The following are the key points:. For more details regarding security levels, see the Security Levels section of the Cisco Series Configuration Guide. Based on an organization's security policy, the security appliance can either pass or drop the packets if they contain content not allowed in the network.

Cisco firewalls support two types of application layer filtering: content filtering and URL filtering. Cisco firewalls can differentiate friendly applets from untrusted applets. If a trusted website sends Java or ActiveX applets, the security appliance can forward them to the host requesting the connection.

If the applets are sent from untrusted web servers, the security appliance can modify the content and remove the applets from the packets. This way, end users are not making decisions regarding which applet to accept or refuse. They can download any applets without taking extra precautions. The security appliance searches for these tags for traffic that originated on a preconfigured port. A local content filtering server can be set up on the security appliance by using the filter command, followed by the name of the type of content to be removed.

The following shows the complete command syntax:. Cisco firewalls can delegate packet-filtering responsibilities to an external server. Administrators can define an external filtering server by using the url-server command. For example, the complete command syntax to specify a Websense server is:. Note: Users may experience longer access times if the response from the filtering server is slow or delayed. This may happen if the filtering server is located at a remote location and the WAN link is slow.

In addition, slow response times may also result if the URL server cannot keep up with the number of requests being sent to it. The url-server command does not verify whether a Websense or SmartFilter server is reachable from the security appliance. You can specify up to 16 filtering servers for redundancy. If the security appliance is not able to reach the first server in the list, it tries the second server from the list, and so on.

One must be deleted before the other is set up. Firewall software offers an adaptable and scalable modular policy framework. For traffic flows traversing the firewall, flow-based policies can be established for any administratively defined criteria and then applied to a set of security services, such as firewall policies, inspection engine policies, quality of service QoS policies, and VPN policies, with each specified traffic flow providing more granular and flexible inspection control.

IP spoofing occurs when a potential intruder copies or falsifies a trusted source IP address. This is typically employed as an auxiliary technique for countless types of network-based attacks.

Cisco firewalls contain several features to enhance the ability of the network to defend itself. Antispoofing is one such feature, which helps to protect an interface of the ASA by verifying that the source of network traffic is valid.

This section discusses some antispoofing features. This security feature works by enabling a router to verify the reachability of the source address in packets being forwarded.

This capability can limit the appearance of spoofed addresses on a network. If the source IP address is not valid, the packet is discarded. Normally, the security appliance examines only the destination address when determining where to forward the packet. For any traffic to be allowed through the security appliance, the security appliance routing table must include a route back to the source address.

See RFC for more information. To enable uRPF, enter this command:. When administrators use uRPF in strict mode, the packet must be received on the interface that the security device would use to forward the return packet. Dropping this legitimate traffic could occur when asymmetric routing paths exist in the network.

When administrators use uRPF in loose mode, the source address must appear in the routing table. Administrators can change this behavior using the allow-default option, which allows the use of the default route in the source verification process. In addition, a packet that contains a source address for which the return route points to the Null 0 interface will be dropped. An access list may also be specified that permits or denies certain source addresses in uRPF loose mode.

Care must be taken to ensure that the appropriate uRPF mode loose or strict is configured during the deployment of this feature because it can drop legitimate traffic. Although asymmetric traffic flows may be a concern when deploying this feature, uRPF loose mode is a scalable option for networks that contain asymmetric routing paths.

This RFC is a widespread resource, particularly for the Internet edge, because in such an environment the boundary between private and public addresses in the sense of RFC is clearly demarcated. It is usually appropriate for an antispoofing access list to filter out all ICMP redirects regardless of source or destination address.

These are just basic guidelines and can be further fine tuned with other filtering such as anti-bogon, which filters traffic that claims to be sourced from reserved addresses or from an IPv4 block that has yet to be allocated by the Internet Assigned Numbers Authority IANA. In general, antispoofing filters are best deployed as input access lists; that is, packets must be filtered at the arriving interfaces, not at the interfaces through which they exit. The input access list also protects the firewall itself from spoofing attacks, whereas an output list protects only devices behind the firewall.

Through the stateful application inspection used by the Adaptive Security Algorithm, the Cisco ASA tracks each connection that traverses the firewall and ensures that it is valid. The firewall, through stateful inspection, also monitors the state of the connection to compile information to place in a state table. With the use of the state table in addition to administrator-defined rules, filtering decisions are based on context that is established by packets previously passed through the firewall.

The implementation of application inspections consists of these actions:. By default, the configuration includes a policy that matches all default application inspection traffic and applies certain inspections to the traffic on all interfaces a global policy. Not all inspections are enabled by default. Only one global policy can be applied. If it is necessary to alter the global policy, one must either edit the default policy or disable it and apply a new one. An interface policy overrides the global policy.

The default policy configuration includes these commands:. To disable global inspection for an application, use the no version of the inspect command. Enhanced HTTP inspection is disabled by default. To enable HTTP application inspection or change the ports on which the security appliance listens, use the inspect http command in class configuration mode. Class configuration mode is accessible from policy map configuration mode.

To remove the configuration, use the no form of this command. When used in conjunction with the http-map argument, the inspect http command protects against specific attacks and other threats that may be associated with HTTP traffic. Any HTTP flow that does not adhere to the basic checks is dropped by default. Many HTTP applications, even internal applications, do not conform.

The action can be changed from dropped to logged, if required. Note : The error message appears as shown when double encoding is used in some URLs. If access to this type of website is necessary, administrators can disable strict HTTP inspection. To remove global inspection for the FTP application to which the Cisco ASA listens, administrators are advised to use the no inspect ftp command in class configuration mode. Without stateful inspection, ICMP can be used to attack a network.

Commands to enable ICMP inspection follow:. These addresses can be used to source attacks that could make it difficult or impossible to trace back to the source. Filtering these addresses at your network boundary will provide another layer of security. The official list of unallocated bogon Internet addresses is maintained by Team Cymru. They also maintain a page dedicated to filtering these bogon addresses at The Bogon Reference.

Antispoofing will ensure that DoS attacks are not launched from inside the network. Administrators are advised to follow this procedure to enable antispoofing on the inside interface to ensure DoS attacks are not inadvertently being launched from the inside the security appliance.

Step 1: Identify the traffic to apply connection limits using a class map. Cisco ASA supports the threat detection feature in software versions 8.

Using basic threat detection, the security appliance monitors the rate of dropped packets and security events caused by the following:. The show threat-detection rate command is used to identify potential attacks when the administrator is logged in to the security appliance. When the security appliance detects a threat, it immediately sends a system log message Note: Basic threat detection affects performance only when there are drops or potential threats.

If the external device responds with an ACK packet, the security appliance knows it is a valid request and not part of a potential SYN attack. The security appliance then establishes a connection with the server and joins the connections together. If the security appliance does not get an ACK back from the server, it aggressively times out that embryonic connection.

Other options are to configure maximum connections, maximum embryonic connections, and TCP sequence randomization in the NAT configuration. If these settings are configured for the same traffic using both methods, the security appliance uses the lower limit. To set the maximum connections both TCP and UDP , maximum embryonic connections, per-client-embryonic-max, or per-client-max, or to indicate whether to disable TCP sequence randomization, administrators can enter this command:.

Recall that the per-client-max and per-client-embryonic-max is an integer from 0 through and the default is 0, which means no limit on connections.
