| Description |
|---|
| Synchronization of internal system clocks with an authoritative source provides uniformity of time stamps for systems with multiple system clocks and systems connected over a network. |
| ℹ️ Check |

| ✔️ Fix |
|---|
| Configure NTP clock synchronization. Configure NTP: device#configure terminal device(config)# ntp device(config-ntp)#server 216.239.35.8 (example IP) device(config-ntp)# write memory Configure NTP with authentication: device#configure terminal device(config)# ntp device(config-ntp)#server 216.239.35.8 (example IP) device(config-ntp)#authentication-key key-id 1234 sha1 testntpsession device(config-ntp)# write memory |
