DHCP server and descriptions for reserved addresses

_slv_ — Mon, 22 Jul 2013 06:40:06 GMT

Hello

I'm using dhcp server on PAN for few small LAN. I'd would like to have ability to put label for reserved addresses. I beleave that it's usable for most of us but impossible in 5.0.5 PAN.

Did someone asked for such FR?

With regards

Slawek

Hi,

Could you please confirm if you are hitting below mentioned Bug on PAN-OS 5.0.5

47237—When mapping an IP address to a MAC address for DHCP reservation, the firewall would not normalize the upper case and lower case letters entered for the MAC address format. So, the MAC address aa:aa:aa:aa:aa:aa and aa:aa:aa:aa:aa:AA were each regarded as unique MAC addresses. This issue caused errors and misconfiguration when more than one IP address was reserved for the same MAC address.

Thanks

I was thinking about third column in

I'd like to make a comment for every entry, because ie after few months Im not remember whos this MAC is.

Last time I had a problem wirh DHCP (with mode set to auto) that stoped working. If I set it to disable > commit > set to enable > commit it started working again for few days. I have case opened with support and we are woring on it.

I have another thing related to DHCP server.

Why "duration" and "lease time" column is empty for reserwerd IPs? this IPs gets IP from this DHCP server. It's a bit confising me.

admin@PA-200> show dhcp server lease ethernet1/4.110

interface: "ethernet1/4.110"

ip mac state duration lease_time

192.168.110.121 00:1c:27:00:d0:2a reserved

192.168.110.122 00:1c:27:01:45:a3 reserved

192.168.110.123 00:1c:27:01:45:80 reserved

192.168.110.124 00:1c:27:01:45:a0 reserved

192.168.110.125 00:1c:27:01:45:86 reserved

192.168.110.126 00:1c:27:02:41:8e reserved

Hi,

Sorry, i could not understand the issue at first point. Now I have checked few of our PAN-OS versions ( including the latest one) and could not find the option to add a label for "reserved address".

Thanks

Hi,

If you reserve an IP address for a particular MAC address, it means as long as the host ( MAC you have reserved) is active in the network, the PA firewall will always assign the same IP address to that host ( static binding). So, the last 2 column ( duration and lease time) will be invalid in this case. That is the reason, in case of static binding, PA firewall is not showing duration and lease time info here.

Thanks

I know there isnt such option. I would request for it as a feature requests. I put this topic because I beleave that probably someone requested it already.

>Now I have checked few of our PAN-OS versions ( including the latest one) and could not find the option to add a label for "reserved address".

In my opinion even it's a static one - information when last time this IP was renewed is important information (when last time device requested IP).
