Before using this guide, one or more Cisco APICs should already be deployed with the Nexus leaf and spine switches already discovered and registered with the APIC. The node ID numbers and names used in the examples in this guide are listed in the following table.
Node ID | Node name |
101 | Leaf1 |
102 | Leaf2 |
201 | Spine1 |
Requirements
The networks used are shown in the following table along with the corresponding bridge domain and application EPG names used in APIC configuration in this guide for the example of a 100 GbE solution with a Cisco ACI environment.
VLAN ID | VLAN name | Gateway IP address/ mask | Bridge domain name | Application EPG name |
1811 | ESXi_Mgmt | 172.18.11.254/24 | ESXiMgmt-BD1 | ESXiMgmt-EPG1 |
1812 | vMotion | 172.18.12.254/24 | vMotion-BD1 | vMotion-EPG1 |
1813 | vSAN | 172.18.13.254/24 | vSAN-BD1 | vSAN-EPG1 |
1814 | App | 172.18.14.254/24 | App-BD1 | App-EPG1 |
1815 | Web | 172.18.15.254/24 | Web-BD1 | Web-EPG1 |
1816 | DB | 172.18.16.254/24 | DB-BD1 | DB-EPG1 |
While a production ACI environment has multiple Application Policy Infrastructure Controllers (APICs), this example uses a single APIC (APIC-1).
All Dell PowerEdge rack servers and MX compute sleds in this example are running VMware ESXi 7.0-update-3.
VMs named app, web, and db on the ESXi hosts are running Ubuntu Linux. A third rack server is used as a jump-box to assist the vCenter configuration and is accessible over the OOB management network.
The Cisco ACI environment has three PowerEdge rack servers that are directly connected to the ACI leafs. These rack servers are in a VMware vSphere cluster, with a vCenter VM named ESXi-MGMT on Rack Server-1, as shown in the Validated environment for 100 GbE solution section.
The environment uses six networks that are shown in the following table:
VLAN ID | VLAN name | Description | Network address | Gateway address |
1811 | ESXi_Mgmt | ESXi host in-band management | 172.18.11.0/24 | 172.18.11.254 |
1812 | vMotion | VM migration | 172.18.12.0/24 | 172.18.12.254 |
1813 | vSAN | Storage | 172.18.13.0/24 | 172.18.13.254 |
1814 | App | VM data network | 172.18.14.0/24 | 172.18.14.254 |
1815 | Web | VM data network | 172.18.15.0/24 | 172.18.15.254 |
1816 | DB | VM data network | 172.18.16.0/24 | 172.18.16.254 |
VMs in the validated environment use the IP addresses shown in the following table:
VM name | VLAN name | IP address |
MGMT | ESXi_Mgmt | 172.18.11.150/24 |
App01-App04 | App | 172.18.14.1-4/24 |
Web01-Web04 | Web | 172.18.15.1-4/24 |
DB01-DB04 | DB | 172.18.16.1-4/24 |
