Hi,

I'm trying to configure NTP with DNS resolution on my switchs ( ntp server dns-name ) but apparently the switch do the resolution and fix the IP adress on configuration. When i change the IP address of my ntp server, there's no more synchronization.

Can we force switch to do resolution periodically ?

Thanks

this is a part of the configuration

CRSF-VIRT-COEUR1(config)#ntp server ntpa1X.X.X. source vlan 90 prefer

Translating "ntpa1X.X.X.X"...domain server (210.X.X.140) [OK]

CRSF-VIRT-COEUR1(config)#

CRSF-VIRT-COEUR1#sh run | i ntp

ntp clock-period 17179582

ntp server 220.X.X.16 source Vlan90 prefer

Thanks
