Table 4 summarizes the assignment of eight fabric links with the max-link parameter set to 8; the interfaces are
divided into eight groups.

of physical links used.
Note:
associated host interfaces are brought down and will remain down until the fabric interface is restored.
PortChannel Fabric Interface Connection
The PortChannel fabric interface provides an alternative method of connection between the parent switch and the
Cisco Nexus B22HP fabric extender. In this mode of operation, the physical fabric links are bundled into a single
logical channel. This approach prevents a single fabric interconnect link loss from disrupting traffic to any one
server. The total bandwidth of the logical channel is shared by all the servers, and traffic is spread across the
members through the use of a hash algorithm.
●
For a Layer 2 frame, the switch uses the source and destination MAC addresses.
●
For a Layer 3 frame, the switch uses the source and destination MAC addresses and the source and
destination IP addresses.
Since both redundancy and increased bandwidth are possible, configuration of the fabric links on a PortChannel is
the most popular connection option.
