DHCP client most most probably partially broken for NTP

Hi all.

If to configure DHCP client on innovaphone IPVA.

If innovaphone once get NTP server by DHCP. It is not possible anymore to change it.

It completely ignore manual NTP settings and also ignore changes on DHCP server.

After small investigation appeared that IPVA after first DHCP discovery create variable: DHCP0/LAST-LEASE And never overwrite part of it even if DHCP server send completely another values for NTP.

Is any way to clear this variable ?

I also have a question: How to use Maintanance/Diagnostics/Command ?

Because if i enter any CLI command i constantly get 404 Not found. It is nothing written about Maintanance/Diagnostics/Command in wiki.

This is correct. DHCP configuration overwrite local configuration

Re: DHCP client most most probably partially broken for NTP

Hi thanks for answer.

yes i understand that it overwrite. But even if i remove in DHCP server NTP server settings from distribution it is still continue to use values got from dhcp. And ignore static values.

i use 12r2 sr13 IPVA[12.5410]

I will try to use latest version but not sure that it will solve issue because i attentively read changelogs and not see that it fixed or at least reported as caveat.

My excuses. After capture DHCP traffic, appeared that it is bug on mikrotik router which include NTP servers configured in SNTP client even if it disabled in DHCP settings. So with innovaphone everything fine.
