The organizational specific TLV list is limited to store 256 entries per neighbor. If TLV entries are more than 256, then the oldest
entry (of that neighbor) in the list is replaced. A syslog message appears when the organization specific unrecognized TLV list
exceeds more than 205 entries (80 percent of 256) for you to take action. Following shows the syslog message:
