User Guidelines
CDP supports two caches to save received CDP messages:
• main cache
• secondary cache
The main cache contains the full received CDP messages about limited number of
the neighbors.
The secondary cache contains partially information about all neighbors.
Use the show cdp neighbors [
interface-id
] detail command to display the main
cache.
Use the show cdp neighbors [
interface-id
] secondary command to display the
Secondary cache.
