Multiple uplinks from a leaf switch to a spine switch is supported. A symmetrical topology is recommended
so that all devices have equal access to resources.
Note
Step 1
For the transceivers with removable cables, make sure that the transceivers are separated from their interface cables.
Step 2
Insert the appropriate transceiver into an active uplink port on the leaf switch.
Step 3
Insert the same type of transceiver in the spine switch port on the line card.
Step 4
For transceivers with removable cables, insert the interface cable into the open end of each of those transceivers.
Step 5
Repeat Steps 1 through 4 for each spine switch in the ACI fabric.
The leaf switch is connected to each spine switch in the ACI fabric.
Step 6
Repeat Steps 1 through 5 for each leaf switch in the ACI fabric.
Each leaf switch in the ACI fabric is connected to each spine switch in the network,
The fabric automatically implements Equal Cost Multi-Pathing (ECMP) and enables all links. You do not
need to configure the links.
Installing a Gigabit Ethernet module (GEM)
Step 1
Clear the switch's current configuration by using the
setup-clean-config
command.
Step 2
Power off the switch by disconnecting the power.
Step 3
Replace the current GEM card with the new GEM card.
Step 4
Power on the switch.
Virtual Port Channel Migration - Migration of Nodes from a
First-Generation Switch to a Second-Generation Switch
Initially the fabric is configured with vPCs between two first-generation switches. Traffic flows are designed
so that only these vPCs are used for data traffic. Now that you want to migrate both of the first-generation
switches to second-generation switches, the following steps are required.
For this procedure, vPC primary and vPC secondary are first generation switches in vPC pair, sending traffic
as described above.
To determine which transceivers, adapters, and cables support this switch, see the
document.
