IPv6 Management Features

SNTP and Timep

 

Configuring an IPv6 Address for an SNTP Server

 

 

N o t e

To use a global unicast IPv6 address to configure an IPv6 SNTP time server

 

on the switch, the switch must be receiving advertisements from an IPv6

 

router on a VLAN configured on the switch.

 

To use a link-local IPv6 address to configure an IPv6 SNTP time server on the

 

switch, it is necessary to append %vlan followed immediately (without spaces)

 

by the VLAN ID of the VLAN on which the server address is available. (The

 

VLAN must be configured on the switch.) For example:

 

fe80::11:215%vlan10

 

Syntax:. [no ] sntp server priority < 1 - 3 > < link-local-addr>%vlan< vid > [1 - 7]

 

[no ] sntp server priority < 1 - 3 > < global-unicast-addr> [1 - 7]

 

Configures an IPv6 address for an SNTP server.

server priority < 1 - 3 >: Specifies the priority of the server ad­ dressing being configured. When the SNTP mode is set to uni­ cast and more than one server is configured, this value determines the order in which the configured servers will be accessed for a time value. The switch polls multiple servers in order until a response is received or all servers on the list have been tried without success. Up to three server addresses (IPv6 and/or IPv4) can be configured.

<link-local-addr >: Specifies the link-local IPv6 address of the destination device.

%vlan< vid >: Suffix specifying the interface on which the des­ tination device is located. No spaces are allowed in the suffix.

<global-unicast-addr>: Specifies the global IPv6 address of the destination device.

[ 1 - 7 ]: This optional setting specifies the SNTP server version

expected for the specified server. (Default: 3)
