Lists the neighboring CDP devices the switch detects,
with a subset of the information collected from the
device’s CDP packet. (For more on this topic, refer to
table 13-4, “CDP Neighbors Data” on page 13-39.)
[ [e] port-numb [detail] ]
Lists the CDP-aware device connected to the specified
port. (Allows only one port at a time.) Using detail
provides a longer list of details on the CDP-aware
device the switch detects on the specified port.
[detail [ [e] port-num ] ]
Provides a list of the details for all of the CDP-aware
devices the switch detects. Using port-num produces a
list of details for the selected port.
