Command Manual (For Soliton) – NTP
H3C S3100 Series Ethernet Switches
Chapter 1 NTP Configuration Commands
1-15
authentication-keyid key-id
: Specifies the key ID used for sending messages to the
peer. The
key-id
argument ranges from 1 to 4294967295. By default, authentication is
not enabled.
priority
: Specifies the peer identified by the
remote-ip
argument as the preferred peer
for synchronization.
source-interface Vlan-interface vlan-id
: Specifies an interface whose IP address
serves as the source IP address of NTP message sent to the peer.
vlan-id
is the VLAN
interface number.
version number
: Specifies the NTP version number. The version number ranges from
1 to 3 and defaults to 3.
Description
Use the
ntp-service
unicast-peer
command to configure an Ethernet switch to
operate in the symmetric-active peer mode.
Use the
undo ntp-service
unicast-peer
command to remove the configuration.
By default, no NTP operate mode is configured.
Note:
If you use
remote-ip
or
peer-name
to specify a remote device as the peer of the local
Ethernet switch, the local switch operates in the symmetric-active peer mode. In this
case, the clock of local Ethernet switch and that of the remote device can be
synchronized to each other.
Example
# Configure the local switch to obtain time information from the peer with the IP address
128.108.22.44 and also to provide time information to the peer. Set the NTP version
number to 3. The source IP address of NTP messages is the IP address of Vlan-
interface1.
