Packet pacing introduces a delay of 33 ms between packets and 66 ms between retransmissions. This pacing interval reduces the CPUHOG messages, and the adjacency is formed more quickly. This feature is on by default in Cisco IOS Software Release 12.0T and later. This feature is not available in the Cisco IOS Software releases earlier than 12.0T. If you are running Cisco IOS Software code earlier than Release 12.0T and you are seeing CPUHOG messages during adjacency formation, upgrade to at least Cisco IOS Software Release 12.0T or higher code to solve this problem through packet pacing.
