Details
Many secure protocols and auditing functions rely on system times being synchronized with a reliable time source, either within or (where security considerations permit) external to the managed network. One of the most commonly used protocols to accomplish this is the Network Time Protocol (NTP), which can use both local and Internet-hosted servers to synchronize system time across a network. NTP should be configured and enabled on the device prior to enabling secure management protocols.
Solution
For example, to configure a switch to use NTP authentication and connect to a local NTP server at 10.100.1.254 using the switch management port:
switch(config)# ntp authentication
switch(config)# ntp authentication-key 1 md5 myPassword
switch(config)# ntp server 10.100.1.254 prefer
switch(config)# ntp vrf mgmt
