Connecting the Switch to the ACI Fabric
Note
Step 1
From the Cisco APIC GUI, perform the Remove From Controller operation for the operational secondary vPC switch
node.
The Cisco APIC clean reboots the switch. 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.
Note There will be a loss of traffic for a few seconds for the operational secondary vPC when you perform the
Remove From Controller operation.
Step 2 Disconnect the cabling from the first generation switch that you just removed.
Step 3
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 4
Install the second generation switch by following the steps in the "Installing the Switch Chassis" section of the
switch-specific Hardware Installation Guide.
Step 5
Connect the loose cabling that you removed from the first generation switch to the same ports on the second generation
switch.
Step 6
Register the new second generation switch with the Cisco APIC.
When the first generation switches are comprising a vPC, complete the following mandatory
prerequisite steps before you proceed with the second migration path:
a. Due to potential traffic loss, it is recommended that that you perform the vPC migration during
a maintenance window.
b. Before you perform this procedure, the Auto Firmware Update policy must be disabled.
c. Upgrade the Cisco APIC cluster to the 4.2(7v) release if the cluster is running an older release.
Also upgrade the first generation switches to the 14.2(7v) release. Wait for the fabric to converge.
d. Upgrade the Cisco APIC cluster to 5.2(7f) release and wait for the cluster to become "Fully Fit."
e. Ensure that the new second generation switches are preloaded and running the equivalent release
as the Cisco APICs, that is 15.2(7f) release. Other than source and target version software releases
4.2(7v)/14.2(7v) and 5.2(7f)/15.2(7f), no other software releases are supported for this migration
procedure.
• The number of ports and port types of the second generation switches must match the first generation
switch that you are replacing. If the number does not match, then you must change the configuration to
accommodate the new ports or port types. This is also applicable if you migrate the hardware while
retaining the same software version.
• To migrate first generation non-vPC leaf switches or first generation spine switches to second generation
switches, follow Step 1, on page 37
vPC-related information is not applicable for this migration.
If you must migrate a first generation non-vPC leaf switch or a first generation spine switch to a second
generation switch, the requirement of the source and target software release 4.2(7v)/14.2(7v) and
5.2(7f)/15.2(7f) is not required. Ensure that the Cisco ACI fabric is running the required software release
that supports the second generation switch PID.
