CDP
An SNMP utility can progressively discover CDP devices in a network by:
1. Reading a given device’s CDP Neighbor table (in the Management Infor-
mation Base, or MIB) to learn about other, neighbor CDP devices
2. Using the information learned in step 1 to go to and read the neighbor
devices’ CDP Neighbors tables to learn about additional CDP devices,
and so on
This section describes CDP operation in a Series 5300XL switches. For infor-
mation on how to use an SNMP utility to retrieve the CDP information from
the switch’s CDP Neighbors table (in the switch’s MIB), refer to the documen-
tation provided with the particular SNMP utility. For information on the object
identifiers in the CDP MIB, see
“CDP Neighbor Data and MIB Objects” on page
10-26.
