NTP Configuration on 5500 series HP HI Switche(JG542A)

Hi,

I am not able to synchronise my HP JG542A  switch with system clock. I am trying to make my switch to act as NTP Server but unable to do the same.

 

I am running ntp-services refclock-master 2 but it is showing unrecognise.

Kindly support

Hi!


I do not know if I understand your case, but you need the switch to synchronize the clock with your NTP server?

 

ntp-service unicast-server XXX.XXX.XXX.XXX (Server NTP).

 

 
 
In answer about your test ..

Hi shiboo

 

I'm not sure what you want to do exactly.

 

Do you :

 

1) Want to synchronise your switch to a ntp server (switch just a client)?

or/and

2) Make your switch a stratum 2 NTP server (that is act as NTP server for other clients).

Re: NTP Configuration on 5500 series HP HI Switche(JG542A)

Hi,

Thanks for the support.

I want to make my switch act as a server with startum 2.

 I am using ntp-services refclock-master 2 command but it showing unrecognise.

Kindly suggest any equivalent of this on for JG542A Hp switch so that i can synchronise it.

 

Also i would like to highligt here i am not using any NTP server in our network.

I will make my core switch to act as NTP server for other networking devices.

 

Hope u will b clear now.

 

Thanks

Hi,

 

according to the command reference

 

http://h20565.www2.hp.com/hpsc/doc/public/display?sp4ts.oid=5195279&docId=emr_na-c03180050&docLocale=en_US

 

the 5500 doesn't support the ntp-service refclock-master command.At least not in software Release 5203 and 5206.

(Not sure which release you're running.)  So, the result of an unreckognized command is to be expected.

 

Seems you ned to configure it in interface specific multicast or broadcast mode if you want to use the 5500 as a ntp-server. See the configuration guide:

 

http://h20565.www2.hp.com/hpsc/doc/public/display?sp4ts.oid=5195279&docId=emr_na-c03180142&docLocale=en_US

 

I would recommend that you find a real unicast server to deliver the NTP service, and then just let the 5500s be clients.

Dunno if its of any interrest for you (since 5500 is doing I think comware v7 while the unit this config is from is running comware v5 (5120)) but in case someone stumbles over this thread in the future.

 

Here comes the config I currently use for NTP:

 

acl number 2000 name v4-DENY-ANY
 hardware-count enable
 rule 0 deny
acl number 2001 name v4-MGMT-NTP
 hardware-count enable
 rule 5 permit source <REMOVED> 0
 rule 10 permit source <REMOVED> 0
 rule 15 deny

#

acl ipv6 number 2000 name v6-DENY-ANY
 hardware-count enable
 rule 0 deny
acl ipv6 number 2001 name v6-MGMT-NTP
 hardware-count enable
 rule 0 deny fragment
 rule 5 deny routing
 rule 10 deny

#

ntp-service source-interface LoopBack0

ntp-service access peer 2001
ntp-service access server 2000
ntp-service access synchronization 2000
ntp-service access query 2000
ntp-service unicast-server <REMOVED>
ntp-service unicast-server <REMOVED>
