On the firewall side, you could be able to see the hit count for the acl is actually increasing.Īccess-list cached ACL log flows: total 0, denied 0 (deny-flow-max 4096)Īccess-list out 2 elements name hash: 0x5589cfeaĪccess-list out line 1 extended permit icmp any any ( hitcnt=4) 0x4f3e126cĪccess-list out line 2 extended permit http any any (hitcnt=0) 0xb4296acc
Then in order to verify the connectivity, you can run the ping test from the web client to server and vice versa. Network Label configuration is also done automatically to ASAv. Important Notice: There is no need to create EPGs explicitly for the firewall internal and external interfaces, instead of that, shadow EPGs will be created by APIC automatically, we will go there later in this article.

From the output below, the web client and web server are learned locally, also we can see they belongs to different BDs. Unicast Routing must be enabled when the consumer EPG and destination end point are in different subnetsĪccess-list out extended permit icmp any anyĪccess-list out extended permit http any anyīefore configuring the L4-L7 integration, make sure the A ccess Policies/VMM Domain configured and interfaces up and in service, the basic configuration of the two EPGs, BDs etc will not be included in this article.L2 Unknown Unicast must be set to Flood for each Bridge Domain.ARP Flooding must be enabled for each Bridge Domain.Each unique interface/direction must be mapped to a unique Bridge Domain.Integration of L4-7 services in ACI requires specific bridge domain networking configuration.
This is needed so that APIC can program the appropriate ports on leaf and also can use this information for troubleshooting wizard purposes. Please note that APIC still needs to know the topology information (LIF, CIF) for the device cluster and devices.

This article will give a configuration example of the unmanaged mode using ASAv in routed mode, how to verify and troubleshoot scenarios will also be given as reference.
The configuration of the L4-L7 device is left to be done by customer. APIC only allocates the network resources and programs the VLAN/VXLAN on fabric side. managed setting is set to false, APIC does not program the device. If a device is configured as “un-managed” i.e. It adds the flexibility for customer to use only network automation for service appliance. The unmanaged mode is also known as Network only switching, which is introduced in Brazos release.
