NTP Client using FQDN on 2930F

  • 1.  NTP Client using FQDN on 2930F

    Posted Sep 20, 2018 01:39 AM

    I'm really hoping this is a big joke.. I'm attempting to configure NTP on an Aruba 2930F switch using a hostname. There doesn't seems to be a way to do this (only IP). Every single other device in my network allows for this but it seems the Aruba isn't having it. Every. Single. One.

     

    us.pool.ntp.org is configured pretty much everywhere.

     

    Am I missing something?? I really don't want to configure NTP on my Palo just to get this switch operating correctly.

    Can you try if ntp server-name will solve your question?

    sw-workshop-putn(config)# ntp ?
 authentication        Configure NTP authentication.
 broadcast             Operate in broadcast mode.
 enable                Enable/disable NTP.
 max-association       Maximum number of Network Time Protocol (NTP) associations.
 server                Configure a NTP server to poll for time synchronization.
 server-name           Configure a NTP server by name to poll for time synchronization.
 trap                  Enable/disable NTP traps.
 unicast               Operate in unicast mode.
sw-workshop-putn(config)# ntp server-name ?
 ASCII-STR             The NTP unicast server name of max 255 chars.

    Is that a new feature? I don't have it on my switch:

     

    HP-Lab-SW1(config)# ntp
 authentication        Configure NTP authentication.
 broadcast             Operate in broadcast mode.
 enable                Enable/disable NTP.
 max-association       Maximum number of Network Time Protocol (NTP)
                       associations.
 server                Configure a NTP server to poll for time synchronization.
 trap                  Enable/disable NTP traps.
 unicast               Operate in unicast mode.

    Is this a version difference? I'm running 16.03:

     

    HP-Lab-SW1(config)# show flash

    The lowest version I have online is 16.05.0004 and it is in there.

     

    I checked this in the release notes and found the command was introduced in WC 16.05.0003:

     

    Specify FQDN for NTP server configuration

    The NTP client takes a fully qualified domain name as input and cycles through the list of IP addresses resulting from the DNS resolution until a reachable NTP server is found. Please refer to the "Time synchronization" chapter in the Management and Configuration Guide for details.
