NTP on HP Switch 5412Rzl2

[Olala1389]

1) I have a local NTP server, 2 core switches and a bunch of access switches. NTP server is on vlan 50. I pointed one core switch to the local NTP server, it is working fine.

2) Management VLAN is, say, 70.

3) I want 1 more core switche to be peer to the 1st core switch and the access switches to point to the 2 core switches and be stratum 4.

# 1 is working fine, how should i proceed with #3? I tried just pointing other switches to the core switch - they don't receive any info. Should i setup an ACL or would the exchange happen on the Management vlan? I don't see the appropriate "peer" commands on the switch either. Please advise.

Hi @Olala1389 , the Switch can act as a NTP Server for other peers: it can only act as a NTP Client pointing to other NTP Server(s). Giveng that your scenario can't be deployed the way you want. Generally it's a good practice to configure each switch to point to one ore more NTP servers locally reacheable, why you can't do that on your network?
