DHCP Lease Time

[DCIM_Support]

I was wondering if there was a way to extend the DHCP lease period? The devices seem to be only getting the DHCP address for 3600 seconds and even then are renewing every 30 minutes anyway. But it fills the log with meaningless messages and can hide other important messages.

Alternatively, is there a way to stop the device from logging the DHCP address update notifications?

Hi Riley,

Sorry but no, there is no configuration option in DCE for DHCP lease time. 

For configuring devices, k-base FA156188 explains the syntax used for event action configuration both through the config.ini upload and using DCE's mass configuration option:

I don't have a system with DHCP running so I can't validate the code for you but if you download the event log from the NMC, you'll see that the txt file has the event codes associated with each event in the log. Here's an example:

11/25/2000 14:18:57 apc FTP user 'apc' logged out from 10.10.253.199. 0x0020
11/25/2000 14:18:32 apc FTP user 'apc' logged in from 10.10.253.199. 0x0016
11/25/2000 09:14:06 apc FTP user 'apc' logged out from 10.10.44.53. 0x0020
11/25/2000 09:14:05 apc FTP user 'apc' logged in from 10.10.44.53. 0x0016

Simply use DCE or the config.ini utility to edit that event as described in the k-base I provided..

I can't say with 100% certainty that all events are configurable.

Thanks,

Steve.

Thanks for that. I'll give it a go and see how it works.

I couldn't find the event code as you mentioned above (the device is an ACRC502 running v3.7.7), but I did see that the event was a 'Network service started' message. And under the Admin -> Notification tab I was able to find the 'Network service started' event and uncheck to stop it from going to the event log. So hopefully that takes care of it.

Thanks for pointing me in the right direction!

I was wondering if that might not be the event. If you do still see issues however, you may want to contact your local support teams. I know the lease is short but I don't usually see that event so often. There could be an issue with DCE and the DHCP server.

The DCE is the DHCP server in this case though:

(Under Server Administration Settings -> Network Settings -> Private LAN)

But there doesn't seem to be any way of configuring DHCP time intervals.

Yes Riley, I understand that DCE is the DHCP server and I understand that it is not configurable for lease time. I noted that in my initial response.

Still I do not always see the event in the device's log all the time. Additionally, I'm simply stating that if you run into issues with the DHCP aspect of your configuration down the road (not just event in the log), you may want to speak with someone in support directly.
