11. Aggregate the two physical links between the two Cisco switches in the stack into a single
logical link, as follows:
Creating a port-channel interface Port-channel 1
12. Set the interface connection to the router, as follows:

sw01(config)# interface GigabitEthernet1/0/1 The single logical link provides
both reliability and higher capacity.
When possible, the two links of the
port channel should be on
different switches to provide
reliability in case a complete switch
goes down. In this reference
configuration, stacked switches are
used, so both ports are not on the
same switch. The manual
configuration of the port channel
is required when the interfaces are
on different switches.
