Москва, Новозаводская ул., 18, стр. 1

 sntp client mode { broadcast | unicast | anycast [ key number ] | multicast }

 no sntp client mode

For example:

! Configure SNTP client to operate in anycast

QTECH(config)#sntp client mode anycast

11.2.3 SNTP client unicast server configuration

In unicast ode, SNTP client must configure server address. The related command is as

following:

 sntp server ip-address [ key number ]

 no sntp server

Only in unicast, configured server address can be effective.

For example:

! Configure unicast server ip-address to be 192.168.0.100

QTECH(config)#sntp server 192.168.0.100

11.2.4 SNTP client broadcast delay configuration

SNTP client broadcast delay configuration is as following:

 sntp client broadcastdelay milliseconds

 no sntp client broadcastdelay

Only in broadcast (multicast), configured transmit delay can be effective. After configuration,

SNTP client can add transmit delay after obtaining time from server to adjust current system

time.

For example:

! Configure broadcastdelay to be 1 second

QTECH(config)#sntp client broadcastdelay 1000

11.2.5 SNTP client multicast TTL configuration

Use following command to configure ttl-value of multicast packet:

 sntp client multicast ttl ttl-value

 no sntp client multicast ttl

This command should be effective by sending packet through multicast address in anycast

operation mode. In order to restrict the range of sending multicast packet, TTL-value setting is

suggested. The default ttl-value is 255.

For example:

! Configure TTTL-value of sending multicast packet to be 5

QTECH(config)#sntp client multicast ttl 5

11.2.6 SNTP client poll interval configuration

Use following command to configure poll-interval of SNTP client in unicast or anycas:

 sntp client poll-interval seconds

 no sntp client poll-interval

Only in unicast and anycast mode, configured poll interval can be effective. SNTP client sends

requirement in a poll interval to the server to adjust current time.

For example:

! Configure poll-interval to be 100 seconds
