DHCP static maps & Client IDs

I'm thinking of implementing DHCP service on my Xserve. I see that when an Airport Extreme Base Station runs a DHCP server, you can create static maps with the individual computers/clients identified by their DHCP Client ID, something which I would find useful. AFAICT, this is not possible in Leopard Server's DHCP server, but it seems so unlikely that the AEBS has MORE functionality than Leopard Server.
Am I right, or is it possible to map static IP addresses by Client ID in Leopard Server?

Leopard Server does support static maps - it's right there in the Server Admin GUI.
Yes, I think I mentioned that.
However it's based off client MAC address, not Client ID.
So that's a no then.
Which means an AirPort Extreme Base Station has greater functionality than Leopard Server:-(

DHCP static maps configuration using serveradmin (terminal / commandline)

Hi there,
I'm having much trouble using serveradmin to create new static map entries. Unfortunately using the serveradmin-tools gui isn't an option, because setting up DHCP static maps are only one small part of a much bigger script.
I tried to manually execute every line. I've also tried the example from the command line manual, but everything without success.
I would be very glad, if someone could help me solving this problem.
So here is the the output of my script...
every executed line leads to a
"dhcp:static_maps = emptyarray"
message.
serveradmin settings dhcp:staticmaps:_arrayid:29d9e547-8b47-ab37-ab28-5a00be4031bf = create
serveradmin settings dhcp:staticmaps:_array_id:29d9e547-8b47-ab37-ab28-5a00be4031bf:ipadress = "xxx.yyy.zzz.220" (this line with a correct IP belonging to the configured subnet)
serveradmin settings dhcp:staticmaps:_arrayid:29d9e547-8b47-ab37-ab28-5a00be4031bf:name = "computer"

finding spelling mistake will solve some problems....
so I wrote adress instead of address.

DHCP static maps ignored

No answers on any other threads, so starting a new one.
XServe running Server 10.6.2. Configured the DHCP service with a dynamic range and about a dozen static maps. Started the service and forced a lease renewal on a client that had a static map. Watched the DHCP messages and an address was assigned - FROM THE POOL.
For some reason, even when receiving a request from a client with a MAC address that's defined in a static map, the DHCP server totally ignores this and hands out an address from the main pool which is obviously nonsense.
Is anyone satisfactorily using static mapping in Snow L Server's DHCP service? Is there some 'extra' configuration that needs to be applied to tell it to use the static maps that are defined? There must be a solution to this, without it DHCP is USELESS. Surely someone has a clue about what's going on here. Please?

I fixed my problem.
In order for Apple's chosen DHCP server to use static maps, you have to enable this in the configuration file - something Apple in their infinite wisdom have forgotten to do.
By default in the /etc/bootpd.plist file bootp is disabled:-
<key>bootp_enabled</key>
<false/>
Change this to:-
<key>bootp_enabled</key>
<array>
<string>en1</string>
</array>
Or for whichever ethernet interface you want to serve these addresses from.
Well done Apple.

How do I remove a DHCP static mapping that will not go away in Server Admin?

I have a static DHCP mapping to a retired network that I can't remove from the Server Admin GUI.
To be specific, I click remove and it disappears.
To then click "SAVE" and it comes back.
How do I remove it manually? Where are the static mappings located that make it reappear each time I click "SAVE".
From the DHCP logs:
Jun 28 18:36:18 macmini-home servermgrd[97]: servermgr_dhcp:bootp config:Notice:Removed record GabrielHouse-Gateway
Jun 28 18:36:27 macmini-home servermgrd[97]: servermgr_dhcp:bootp config:Error:Unable to update/remove record with id 45F7E04B-6368-419C-9A86-64458BBAC5C0 because 12 records found.

Hi John,
Thank you for taking the time to write up the approach and places to start.
I have checked in all of the places listed and no luck. No occurance of the "stuck" statically mapped DHCP address. Just to add a note, of detail about the particular device in case this is a client device that is causing this .... The device is an iPhone and it is NOT using the bad static assignment. Also, the static record is an IP address that is now outside of the current network range..... It is 192.168.0.25 .... where as the current DHCP server range is in the 10.1.XX.XX range.
Also, This server is not using Open Directory, but I did open WGM to see what I could see thru the GUI and I found no record in the local database.
Also, note - I attempted to delete ALL DHCP configuration on this server by
1) Exporting the configuration data with Server Admin
2) Manually removing the bad DHCP static assignment in the plist
3) Turning off the DHCP Server
4) Deleting the full DHCP zone.
5) Importing the DHCP configuration from the edited plist.
6) Turning on DHCP Service.
The bad record is back....
Thanx for the ideas. Keep them coming....

Need to Import DHCP Static Maps

I just built an 10.6 OS X Server that will be running DHCP, I have the DHCP mappings in a spreadsheet with the Description, IP and Mac address. I need a way to import them, any ideas which tool I can use?
I have already tried Leopard Static Mapper 1.1, the plist I created with it won't load, I think it only works with 10.5

Hi Flipwork,
thanks for a quick update. I have checked and double checked and triple checked. I even removed the names etc. from description fields. They are simply numbers now from 1 to 1820... yea that is how many I have to import. The other fields are simple mac addresses and IP addresses.
the plist starts to get imported in server admin and then stops at a random number depending on which order I give the csv file to static map importer from which the plist is created.
I'll be grateful for a hint that might work for me.
thanks again for your time.
Regards

Dhcp static maps

Hi folks,
I have 10.3.9 server. I would like to achieve following setup:
a] home users should get 192.168.1.1-30
b] guests (mainly powerbooks and macbooks) should get 192.168.1.100-130
the guests are disallowed to connect to server via afp/smb using firewall rule.
I created a static map in netinfo for home users and it's working correctly. However, I don't have 30 machines (1.1-30) but only 20, so I have gaps in the static maps. I'm trying to fill them using dummy records, but it looks like they are ignored. Is there a way how to do it?
My dummy records are as follows:
name=dummy1
en_address=00:FF:00:FF:00:00:00
ip_address=192.168.1.17
name=dummy2
en_address=00:FF:00:FF:00:00:00
ip_address=192.168.1.18

Well, for a start your MAC addresses are invalid. MAC addresses consist of 6 octets, your examples show 7. I don't know if that's an error in copying them to the boards or whether you've really entered them that way, so it might or might not be an issue.
Also, you can't use the same MAC address twice. How is the DHCP server supposed to know which address to hand out when 00:FF:00:FF:00:00 has both 192.168.1.17 and .18? Again, this might just be a transcoding issue in this post rather than a real problem in your setup, but it's worth checking.
I don't know that that'll solve your problem but it's the first things I'd look at.
If you can't find a solution that way, consider reversing the order - put the guest addresses first followed by the private ones. That way guests will get a low-ordered IP address (say, .1-.63) while the home users get a higher address (.64-.96) - note how I've used binary-friendly numbers such as 64 and 96; while it's less obvious to humans it's far easier for the computer, especially in writing firewall rules since 192.168.1.0 through 192.168.1.63 equates to 192.168.1.0/26, or 192.168.1.0/255.255.255.192 and 192.168.1.64 through 192.168.1.95 equates to 192.168.1.64/27 or 192.168.1.64/255.255.255.224. It isn't possible to write a one-line firewall rule that covers .1 through .30 but it is with the IP address ranges I've used.

Offloading DHCP static mapping in 12.3(25)?

According to the following:
http://www.cisco.com/en/US/docs/ios/12_3t/12_3t11/feature/guide/gtdhcpsm.html
...configuring static addresses via DHCP can be accomplished from a text file found on a tftp server as of IOS 12.3(11)T.
I'm running 12.3(25) on a 2621, but I don't see the form of the "origin" command described at the above link. The documentation above states that the syntax is:
origin { dhcp | aaa | ipcp | file <url> }
...yet, I only see the following options:
Router# conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router (config)# ip dhcp pool MYPOOL
Router (dhcp-config)# origin ?
aaa Subnet is from a AAA server
dhcp Subnet is from another DHCP server
ipcp Subnet is from IPCP subnet negotiation
Router(dhcp-config)#
The documentation states that this functionality was released with 12.3(11)T. Am I correct in assuming that it is not available in 12.3(25)?

Dhcp static binding, WS-X45-SUP7-E, sso

Hello, i try to use dhcp static mapping. At WS-X45-SUP7-E in sso mode. It's already good working for me, but i receive this error:
000243: 000202: *Nov 15 14:01:29.540: %DHCPD-4-HA_CONFIG_MISMATCH: STANDBY:DHCP pool mit_stb configuration on Active is not matched on the Standby.
This is my dhcp config.
ip dhcp pool mit_stb
origin file ftp://10.6.1.240/static_pool_mit_stb.txt
default-router 10.50.0.254
How can i solve this error?
UPD: In scope of fixing this error i trying a force-switchover and in result all static bindings was drop, because standby supervisor doesnot know about it. After "no service dhcp" and "service dhcp" commands static bindings is up and network still working good, but upper error was comeback in logs. Therefore my system have no redundancy for this function.
my running-config redundancy section:
redundancy
mode sso
main-cpu
auto-sync standard
Has anyone used this function in SSO mode?

Hi,
In this case you need to make sure that the new sup module is running the same IOS version that the current supervisor, if that is the case then when you insert the new one it will get in sync with the active module and all config will be loaded into the new module, at that point you can use the show module and show redundancy to ensure that the 2 supervisors are in SSO mode once you confirm that then you can force a switchover to the supervisor in slot 3 and once he has take over the box control then you can remove the slot 4 sup.
Hope this helps.

Where can I find the file where the static mapping allocations of the DHCP server are stored?

In our company we are using DHCP to assign static ip addresses to our clients.
Now we are forced to change the ip address range. To prevent changing each allocation
of mac-address to ip-address manually with the admin tool i would like to change the allocation
in the file where the allocations are saved. The reason ist that i just have to use copy & paste for all
the allocations.
So how is the file named and where can I find the file where
the static mapping allocations of the DHCP server are stored? Is it just an ASCII file?
Must i note anything when i change the file manually?

From man bootpd:
BOOTP/DHCP STATIC BINDINGS
     Static IP address to ethernet address bindings are stored in the /etc/bootptab file and in Open Directory. Bindings specified in the /etc/bootptab file take precedence over those in Open Directory.
     See bootptab(5) for more information about the /etc/bootptab file.
     For Open Directory, bootpd looks at the /Computers records for the following properties:
/etc/bootptab is a standard text file, while the records in Open Directory can be manipulated either through the command line, or via Workgroup Manager.

DHCP/Subnets/Static Maps setup question

We have a unique teaching environment where we would like both employees (with laptops) and clients to be able to plug into any ethernet port in the building or be wireless. My question is, what is the best way to set things up so that employees always get the same ip and have access to the full range of services (file services, LDAP, Internet) but customers only have access to the Internet but not internal services. I have tried using static maps for employees but for some reason, customers sometimes end up getting one of the static maps intended for employees (and I have verified that all the MAC addresses are entered correctly). I am pretty new to Tiger server so any help is greatly appreciated.

If im not mistaking your DHCP settings are overlapping with the ips you have statically assigned. To fix this reserve say 192.168.1.1-127 for static ips and let dhcp use the remainder.

Static mapping in 10.3.x Server?

I have a situation where we want to use static mapping (DHCP Reservations in Windows-speak) but cannot upgrade to 10.4 because of a software compatibility issue. Is there a way to enable/add this feature on 10.3.x? Thanks!

To achieve what you want you'll need to change the server setup. Start by making your server an OD master and use different named LDAP accounts on the server for the clients (or remove/rename the local accounts (folders) first).
The clients need to use LDAP info to find the server (look in Directory Access).
Older OS X server versions used Netinfo domains (Jaguar too? at least 10.1.x did).

No router add on static ip clients

trouble with my server, 2 ethernet port, one for wan, one for lan. NAT. client with dhcp attributed address receive also the router address but static client does not!!
will appreciate any help.
thx

eh man why will i use a server and then manually configure the clients?!
"client pull ip address from server static maps but receive only ip and subnet and not the router address inputed in the subnet config pane of the server, only the clients in the dynamic range receive the router address"
is that normal? should i manually configure my static clients?
had already took quite a lot of time for the static mapping!! is there something ive missd in the configuration?

Flexconnect static mapping of WLAN to VLAN

5508 running 7.4
I want to create a definition for a particular site that maps WLANs (SSIDs) to switched VLANs. I know that I can go to Wireless => Select AP => VLAN mappings on an individual AP basis. But is there a way to create a group that will do this? I thought it could be done with flexconnect groups but I just could not find a way to make it happen there. Then I ran across this Architecting Network for Branch Offices with Cisco Unified Wireless Cisco Live presentation:
http://d2zmdbbm9feqrf.cloudfront.net/2013/usa/pdf/BRKEWN-2016.pdf
And on page 28 it states:
AP groups give the ability to statically map Wi-Fi service (WLAN) to VLAN based on physical location
And it then goes on to give a Configuration/VLAN mapping example in which I fail to see where VLANs are mentioned at all.
Is what I am trying to do possible?
Thanks,
-JEff

Hi Scott, thanks for the reply
I have a main campus with several different distribution blocks that each use unique VLAN IDs. And I have about a dozen remote sites that will all use common VLAN IDs. I am configuring a single SSID (WLAN 2) to be used across all of these locations. So at my main campus building "A" will have WLAN 2 mapped to VLAN 55 while building "B" will have WLAN 2 mapped to VLAN 65. At each of the remote sites WLAN 2 needs to be maped to VLAN 15.
So let's say I want to configure the main campus buildings A and B. I create a dynamic interface for vlan 55 and name it something creative like vlan-55, Likewise for vlan 65. Then I create an AP group named APG-55, add WLAN 2 to it and add all of my APs in that buliding. What I don't understand is where the dynamic interface comes into play. From your explanation it would seem that I need to assoiciate the dynamic interface to an AP group somehow. What am I missing?
Thanks!

How to implement an independent static stub client ? Please, help

Hi everybody!
I'm using the jwsdp1.2 and i got the static stub tutorial client to test my webservice. It works fine! However, i tried to compile the client code separately and it didn't worked. The jvm can't find the webservice class. So, the questions are:
- How to implement an independent static stub whithout the ant help?
- How can the client get the endpoint to create the proxy?
- Must I use any javax.xml.rpc interface (call or service maybe) to do the job?
- Could anybody show me some sample code?
Well, that's it. I'm waiting for some answer. Please, help me.
Tks in advance,
Rodrigo.

Can you explain what you mean by "independent static stub" ?
JWSDP Tutorial explains all the steps required to create a static stubs client and invoke the service. In addition, https://jax-rpc.dev.java.net/whitepaper/1.1/index-part2.html#Scenario2 explains the detailed steps to achieve the same from command line.
Hope that helps.
