Qtech QSW-3900-24-SFP-DC [482/634] 2 sntp server

ip-address：Means valid-server interface. Mainframe cannot be 0

wildcard：Similar to reverse the mask

【Command configuration mode】

Global configuration mode

【Usage】

In the mode of broadcast and multicast, SNTP client checks time by receiving

protocol messages sent by all servers. And it cannot filtrate the servers when

spiteful attack exists. To solve this problem, a series of valid servers can be

listed to filtrate source address of the message.

【Example】

！Add a valid-server list

QTECH(config)#sntp client valid-server 10.1.0.2 0.0.255.255

16.1.12 sntp server

Use sntp server command to configure server ip-address in unicast mode.
