For 16 active interfaces, be sure that your switch supports the feature (for example, the Cisco Nexus 7000 with F2-Series 10 Gigabit Ethernet Module).ДЄll interfaces in the channel group must be the same type and speed. For switches that support only 8 active interfaces, you can assign up to 16 interfaces to a channel group: while only 8 interfaces can be active, the remaining interfaces can act as standby links in case of interface failure. You can configure up to 48 EtherChannels, depending on how many interfaces your model supports.Д®ach channel group can have up to 16 active interfaces. A port-channel interface is used in the same way as a physical interface when you configure interface-related features.

When the active interface fails over to the standby, the same MAC address is maintained so that traffic is not disrupted.ДЄn 802.3ad EtherChannel is a logical interface (called a port-channel interface) consisting of a bundle of individual Ethernet links (a channel group) so that you increase the bandwidth for a single network.

Alternatively, you can assign a manual MAC address to the redundant interface, which is used regardless of the member interface MAC addresses. If you change the order of the member interfaces in the configuration, then the MAC address changes to match the MAC address of the interface that is now listed first. The redundant interface uses the MAC address of the first physical interface that you add. You can configure up to 8 redundant interface pairs. This feature is separate from device-level failover, but you can configure redundant interfaces as well as a device-level failover if desired. You can configure a redundant interface to increase the ASA reliability. When the active interface fails, the standby interface becomes active and starts passing traffic. For more visit Cisco KB.A logical redundant interface consists of a pair of physical interfaces: an active and a standby interface.

By default Cisco only monitors вЂњphysicalвЂќ interfaces and if your environment is utilizing sub-interfaces you will need to add them to the mix.

Cisco explanation: вЂњBecause HTTP connections are typically short-lived, and because HTTP clients typically retry failed connection attempts, HTTP connections are not automatically included in the replicated state information.вЂќ For more info visit Cisco KB.

HTTP connection is NOT enabled by default within stateful failover configuration.

recommended if no direct link is available for the pair of firewalls where communication happens via proxy i.e dmz switch or if they are not in close proximity.

Please note that port-channel command is not available on ASAv but it will work with physical appliances. We are going to be using gi0/5 and gi0/6 on both units as our high availability link presented as port-channel.

CiscoASAv9.5.2-204- 2 will be our Secondary firewall.

CiscoASAv9.5.2-204- 1 will be our Primary firewall.First we need to define who will be our primary and secondary unit. In this simple topology we are having a pair of Cisco ASAv running on 9.5.2-204.

In this post IвЂ™ll present how adding (3) additional lines of code can make a difference in your pair of stateful firewalls. Being in the field IвЂ™ve seen it way too many times where customers redundant security appliances have high availability link as a single point of failure.
