Cisco Aci Ping From Apic

In recent years, the software-defined networking (SDN) movement has gained significant traction in the data center, promising to make network configuration and management simpler and more flexible. One of the most popular SDN solutions is Cisco’s Application Centric Infrastructure (ACI), which uses a centralized SDN controller (the APIC) to manage a network of Cisco Nexus 9000 Series switches.

In an ACI network, the APIC is responsible for routing traffic between hosts, so the ping test is slightly different. Instead of sending an ICMP echo request packet directly to the destination host, the source host sends an ICMP echo request packet to the APIC. The APIC then forwards the packet to the destination host. If the destination host is reachable and has ICMP enabled, it will reply with an ICMP echo reply packet, which the APIC will forward back to the source host.

The APIC itself can also be pinged, which can be useful for troubleshooting connectivity issues between the APIC and the switches it is managing. To ping the APIC, the source host sends an ICMP echo request packet to the APIC’s IP address. If the APIC is reachable, it will reply with an ICMP echo reply packet.

In summary, the ping test is a useful tool for troubleshooting connectivity issues in an ACI network. To ping a host, the source host sends an ICMP echo request packet to the APIC, which forwards the packet to the destination host. If the destination host is reachable and has ICMP enabled, it will reply with an ICMP echo reply packet, which the APIC will forward back to the source host. The APIC itself can also be pinged by sending an ICMP echo request packet to its IP address.
