    Limiting Topology Discovery Table Entries

    You can specify the maximum number of discovery table entries that a neighbor can have.

    To specify the maximum number of entries:

    • Issue the max-discovery-table-entries command in L2C Neighbor Configuration mode.
      host1(l2c-neighbor)#max-discovery-table-entries 4000

    You can use the no version to return the maximum number of discovery table entries to its default value, 10,000 entries.

    Note: Using this command to change the maximum number of entries when an already greater number of current entries exists in the discovery table does not remove any existing entries. Instead, future entries are prevented. For example, if the current table contains 5000 entries, and you specify a maximum of 4000 entries, the software does not remove any existing entries from the table. The software prevents any new entries until the number of table entries falls below the specified maximum.
