In this example, two S5248F-ON switches are joined to an existing Cisco ACI environment. The rack contains two S5248F-ON and four PowerEdge R730xd servers.
The connections between the ACI environment and the S5248F-ON switches are a double-sided multichassis link aggregation group (MLAG). The double-sided MLAG connection consists of a vPC on the Cisco ACI side and a VLT port channel on the S5248F-ON side.
The following figure shows that all devices in the validated environment are connected.
In this example, all Dell PowerEdge R730xd rack servers are running VMware ESXi 6.7.0. VMs named "web," "app," and "db" on the ESXi hosts are running Ubuntu Linux guest OSs.
The existing Cisco ACI environment has two PowerEdge R730xd rack servers directly connected to the ACI leaf switches. The following figure shows that these rack servers are in a VMware vSphere cluster with a vCenter VM named mgmtvc01 on R730xd-01.
Integrating the S5248F-ON switches into the Cisco ACI environment enables the four PowerEdge R730xd servers in the rack to join the existing VMware vSphere cluster. This integration enables all hosts and VMs to communicate using the relevant networks.
Table 3 shows the five networks used for the in-band test environment.
