Employeethere is a known issue that vcmp guest is unable to connect to ntp server via mgmt interface in 11.6.0.
ID487233 ntp from a guest is being blocked by host side firewall rules
the following is workaround.
1) add the commands to /config/startup on vCMP host.
iptables -t nat -D PREROUTING -m physdev --physdev-in mgmt_vm_tap_+ -j ACCEPT
iptables -t nat -I PREROUTING 1 -m physdev --physdev-in mgmt_vm_tap_+ -j ACCEPT
2) run the following command at vCMP host bash prompt:
clsh iptables -t nat -I PREROUTING 1 -m physdev --physdev-in mgmt_vm_tap_+ -j ACCEPT
