Set 'key' for each 'ntp server'

OrtaDüzey 2Otomatikcisco-iosxr

Açıklama

Specifies the authentication key for NTP. This authentication feature provides protection against accidentally synchronizing the ntp system to another system that is not trusted, because the other system must know the correct authentication key. CIS marks this Manual; automated: fails if any NTP server has no 'key <id>'. Audited against the hierarchical output of 'show running-config' (run 'terminal length 0' first; not 'show running-config formal').
