Managing NTP Peer Support

An NTP peer is a member of a group of NTP servers. Normally, an NTP peer is used to synchronize clock information among a group of servers that serve as mutual backups for each other. Typically, core switches are configured as NTP peers, and an NTP server is configured as a core switch to an NTP client, aggregation switch, or edge switch. An NTP client can choose the most reliable clock from all servers that have a peer relationship with the client.
