Hi masters, I am new to networking so please bear with me. I need to know on how to check from the switch side (S4048-ON) to verify the connectivity between my switch and the ntp server of one of my client. What command or tool I can use for this job. Troubleshooting done: 1. enable to ping the ntp server from the switch 2. ntp server not syncing on the switch: Clock is unsyncronized, stratum 16, no reference clock frequency is 0.000 ppm, stability is 0.000 ppm... Please advise.
