Configuring a New Peer Association

When you have configured the

NTP

client and/or server, you will need to set at least one

peer association for the switch. An

NTP

peer is a machine of the same stratum that will

compare and check time information sent from the switch, and in turn send time information
to the switch.

To configure a new peer, enter the

ntpaddpeer

command in the following manner:

ntpaddpeer <address> [<keyId> <version> <minpol>] [prefer]

where

<address>

is the either the domain name or IP address of the peer machine. The

optional configuration items are described below:

<keyId>

. An unsigned 32-bit integer key identifier for encryption authentication. The

default is for no key

ID

.

<version>.

The version of

NTP

being used. The options are versions 1, 2, or 3. If no

number is entered, it is assumed that version 3 is being used.

<minpol>.

The minimum poll interval for time checks to this peer. The number entered is

seconds raised to the power of 2.

prefer

. An identifier that marks this peer as a preferred source of time information. In a

situation where multiple peers could provide time information to this client, the preferred
peer is the one that is used.

For example, to add a peer with an address of 1.1.1.1, a key identifier of 5, using version 3 of

NTP

, minimum poll of 16 seconds, and marked as a preferred server, you would enter the

following:

ntpaddpeer 1.1.1.1 5 3 4 prefer

When you have finished press

<return>

. A brief message appears confirming the addition of a

new peer.
