Setting Up An Optional Console Interface - Cisco Nexus 93600CD-GX Series Hardware Installation Manual

Setting Up an Optional Console Interface

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.
Register the new node with the same node name and node ID. This switch becomes part of the fabric. The Cisco APIC
pushes the policies to the new switch and keeps down the vPC legs because there is a mismatch of the generation of
switches. At this point, the vPC primary continues to send the data traffic.
Step 7
Before you proceed to
Step 8 From the Cisco APIC GUI, perform the Remove From Controller operation for the vPC primary. The Cisco APIC
clean reboots the switch.
Wait for about 10 minutes for this operation to finish. The vPC leg on the second generation switch, which the Cisco
APIC kept down earlier, comes up. This action prompts all traffic to move to the new second generation switch. The
vPC ports on the new second generation switch can take a few minutes to come up, during which time there will be
traffic drops. The duration of traffic drops varies by the scale and flows in the fabric.
Step 9 Disconnect the cabling from the first generation switch.
Step 10
Uninstall the first generation switch as you did in
Step 11 Install the second generation switch as you did in
Step 12 Connect the loose cabling as you did in
Step 13
Register the new second generation switch with the Cisco APIC.
Register the new node with the same node name and node ID. This switch becomes part of the fabric. The Cisco APIC
pushes policies to the new switch and the vPC legs comes up and starts passing traffic.

Setting Up an Optional Console Interface

You can optionally set up a console interface for performing the initial configuration of the switch. To do
this, use the interface cable provided in the accessory kit to connect the switch to your console device. You
can connect the console port on the switch to a modem. If you do not connect it to a modem, make the
connection either before powering up the switch or after completing the boot process for the switch.
