Configuration Examples for NTP

This example shows how to configure an NTP server and peer, enable NTP authentication, enable NTP
logging, and then save the configuration in startup so that it is saved across reboots and restarts:
switch# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# ntp server 192.0.2.105 key 42
switch(config)# ntp peer 2001:0db8::4101
switch(config)# show ntp peers
