NTP Server
Supermicro switches can synchronize time with a NTP server.
Follow the below steps to configure NTP server parameters.
Step Command
Description
Step 1
configure terminal
Enters the configuration mode.
Step 2
ntp server <ip_address> [key (1-65535)] [prefer]
Configure the NTP server.
ip_addr
– IP address of server.
key
– Authentication key for server
connectivity in the range of 1-65535.
prefer
–This option can be used to
specify a preferred NTP server when
multiple NTP servers are configured in
the switch. Only one server can be
configured as ‘prefer’ at a time.
Step 3
end
Exits the configuration mode.
Step 4
show ntp
Displays the NTP configuration.
Step 5
write startup-config
Optional step – saves this configuration
to be part of the startup configuration.
The
“enable agent”
command enables the agent. NTP servers can be deleted only when the
NTP status is disabled.
If the key is configured at a Supermicro switch that’s acting as an NTP client, ensure the
same key is configured at the NTP server(s) as well.
The example below shows the commands used to configure an NTP server.
SMIS# configure terminal
SMIS(config)#
ntp server 200.200.200.10 key 100 prefer
SMIS(config)#
ntp server 100.100.100.1 key 500
