On the Cisco Nexus 5000 Series, you can configure a maximum of 16 PortChannels consisting of four or more
ports (because they are hardware PortChannels). With two-port vPCs, you can configure as many virtual
PortChannels as the number of ports available.
Figure 8. How to Count PortChannels on the Cisco Nexus 5000 Series
In addition, a Fibre Channel PortChannel uses resources from the same pool of 16 hardware PortChannels. Thus,
for example, you can have a total of 12 Ethernet PortChannels and 4 Fibre Channel PortChannels, or 16 Ethernet
PortChannels and no Fibre Channel PortChannels.
As Figure 8 indicates for Case C, any PortChannel configured on the fabric extender does not count against the 16
PortChannels that the Cisco Nexus 5000 Series supports.
PortChannels Between Fabric Extender and Cisco Nexus 5000 Series
As shown in Figure 9, if the fabric extender connects to the Cisco Nexus 5000 Series Switch with a PortChannel,
each PortChannel from the fabric extender to the Cisco Nexus 5000 Series Switch consumes one of the bundle
indexes (48 for the Cisco Nexus 5500 platform and 16 for the other Cisco Nexus 5000 Series Switches).
