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:
Syntax:. [no ] sntp server priority < 1 - 3 > < link-local-addr >%vlan< vid > [1 - 7]
5-10
fe80::11:215%vlan10
[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)
