Connecting the Switch to the ACI Fabric

Second-generation Cisco Nexus 9000 Series switches include those switches that have an EX or an FX in the

PID.

Move any APIC controllers that are connected to the migrating vPC first-generation switches to any other

switches in the fabric and wait for the APIC cluster to become "Fully Fit".

Step 1

From the APIC GUI, perform the Remove From Controller operation for vPC secondary. The switch is clean rebooted

by the APIC. Wait for about 10 minutes for this operation to finish. This action prompts all traffic to use the other

first-generation switch for data traffic. Disconnect the cabling from vPC secondary.

Step 2

Uninstall the first-generation switch by reversing the order of the steps in the Installing the Switch Chassis section, of

the switch specific Hardware Installation Guide.

Step 3

Install the second-generation switch by following the steps in the Installing the Switch Chassis section, of the switch

specific Hardware Installation Guide.

Step 4

Connect the loose cabling that you removed from the first-generation switch, to the same ports on the second-generation

switch.

Step 5

Now you register the new second-generation switch with the APIC. Register the new node with the same node name

and node ID. This switch becomes part of the fabric. Policies are pushed to the new switch and the vPC legs are kept

down since there is a mismatch of generation switches. At this point, vPC primary continues to send the data traffic.

Step 6

From the APIC GUI, perform the Remove From Controller operation for vPC primary. This switch is clean rebooted

by the APIC.

Wait for about 10 minutes for this operation to finish. The vPC leg on the second-generation switch, which was kept

down earlier comes up. This action prompts all traffic to move to the new second-generation switch. Please note the

vPC ports on the new second-generation switch will come up in about 10 to 22 seconds when STP is disabled for the

deployed VLANs on the remote devices, and there will be traffic drops in the range of 10 to 40 seconds, depending

upon the flows in the fabric. When STP is enabled on the VLANs on the remote devices, the traffic loss will be in the

range of 40 to 75 seconds, depending upon the flows in the fabric.

Step 7

Disconnect the cabling from the other first-generation switch.

Step 8

Uninstall the first-generation switch, like you did in step 2.

Step 9

Install the second-generation switch, like you did in step 3.

Step 10

Connect the loose cabling, like you did in step 4.

Step 11

ID. This switch becomes part of the fabric. Policies are pushed to the new switch and the vPC legs comes up and starts

passing traffic.
