Configuring Remote Time Servers
You configure remote time servers (peers) for time synchronization in Unicast
Client mode only. Configuring a remote time server involves:
• Adding remote time servers
• Specifying the configuration peer mode for the time server
• Setting the mode of operation of the router
• Specifying a source IP address for the time server
• Specifying peer preference
• Deleting peers
Adding Remote Time Servers
You add remote time servers to the router by specifying the IP address of each
time server (peer). NTP adds the IP address of the time server to a peer list, which
the local NTP client uses when querying remote time servers for time information.
Bay Networks recommends that you configure a minimum of three upper stratum
remote time servers (peers) for a router, since it can apply an agreement algorithm
to detect a problem on any part of the time source. You can, if necessary, add a
maximum of five remote time servers on a device (router, for example).
Configuring multiple remote time servers ensures redundancy in case one peer
fails unexpectedly.
Using the BCC
To specify the IP address of each peer that you want to add to the router, navigate
to the NTP prompt and enter:
peer
address
address
is 0.0.0.0 or any valid IP address.
For example, the following command line adds the peer 2.2.2.2 to the router.
ntp# peer 2.2.2.2
peer/2.2.2.2#
