Displaying Advertisement Data and Statistics
The Link Layer Discovery Protocol (LLDP) provides a standards-based
method for enabling the switches covered by this guide to advertise them-
selves to adjacent devices and to learn about adjacent LLDP devices. The
3400cl and 6400cl switches can also learn about adjacent CDP devices and
map this information to the LLDP database.
The 3400cl and 6400cl switches can read CDP packets received from other
devices, but do not generate CDP packets. .
An SNMP utility can progressively discover LLDP (and CDP) devices in a
network by:
1. Reading a given device's Neighbors table (in the Management Information
Base, or MIB) to learn about other, neighboring LLDP (or CDP) devices.
2. Using the information learned in step 1 to find and read the neighbor
devices' Neighbors tables to learn about additional devices, and so on.
