Using DHCP Option 60 with Aironet APs

Hello,
I'm trying to configure Aironet 1000 series and Aironet 1130 series APs to talk to a wireless controller card inside a 2811 ISR. I have a Catalyst 3550 L2/L3 Switch between my APs and the 2811. So far the Aironet 1000 series found the wireless controller successfully. The following is the current configuration for the 3550 DHCP pool:
ip dhcp pool WLAN_CM
network 172.27.2.0 255.255.255.0
option 60 ascii "Airespace.AP1200"
default-router 172.27.2.1
option 43 ascii "172.27.3.12"
I would like to add another option 60 statement to be able to connect the Aironet 1130 AP. Would this configuration work?:
ip dhcp pool WLAN_CM
network 172.27.2.0 255.255.255.0
option 60 ascii "Airespace.AP1200"
option 60 ascii "Cisco AP c1130"
default-router 172.27.2.1
option 43 ascii "172.27.3.12"
I will try shortly in the lab. I am not sure if I need to create another DHCP pool entirely dedicated for the 1130.
Any input will be much appreciated.

Hello
why do you use option 60?
From my view, the AP needs just to know option 43 to find the controller, but the problem is that the airespace-ap wanna have option 43 in ascii and ios-ap in lwapp mode wanna have the option in hex.
best regards
Oliver

MDT/WDS PXE Deployment - DHCP Options for both x64 and x86

Alright, I've found out the option 66 & 67 information, as what to set for each. The problem I'm trying to figure out is what to use for the boot file for option 67. So far all the info I've found says this:
Configure DHCP option 67 with the right boot image file.
For 32-bits systems \boot\x86\wdsnbp.com
For 64-bits systems \boot\x64\wdsnbp.com
I want to be able to use this for both 32 and 64 bit Windows clients, but cannot find anywhere that specifies how I would be able to do both.

DHCP Options (specifically 067) can have a significant impact on which NBP your client can access. If you specify \Boot\x86\Wdsnbp.com you are forcing the client to the 32bit NBP.
If you specify \Boot\x64\Wdsnbp.com you are forcing the client to the 64bit NBP.
Niether option is an ideal solution, especially if you have a varied environment.
I would take a look at the following article and see if it sheds some light on your question:
PXE booting with WDS – DHCP Scope vs IP Helpers

DHCP option 66

I would love to just post in this thread:
http://discussions.apple.com/thread.jspa?threadID=2347065
But Apple likes to lock old threads and force you to start over...
The indication in that thread is people did get this to work, but there is no final note of exactly how. So far we are finding it does not function properly. We're trying to set up a Fog server, but using the Mac server for DHCP. Unfortunately it fails to actually forward the client to the Fog server as needed. Here is what we have done:
on the Mac server (10.6.4) edit the /etc/bootpd.plist
below the array for dhcpdomainsearch and above the dhcp_router key, we insert the following:
<key>dhcpoption66</key>
<data>
krp+CQ==
</data>
<key>dhcpoption67</key>
<data>
cHhlbGludXguMA==
</data>
These values are obtained using the DHCP Option Code Utility posted in the above thread with these inputs:
Option Code Number: 66
Option Code Type: IP
Option Code Value: 146.186.126.9
Option Code Number: 67
Option Code Type: String
Option Code Value: pxelinux.0
When those didn't work, because the info in the noted thread was not clear, we also tried:
Option Code Number: 66
Option Code Type: String
Option Code Value: 146.186.126.9
Which gave us:
<key>dhcpoption66</key>
<data>
MTQ2LjE4Ni4xMjYuOQ==
</data>
This also did not work. In every case the TFTP times out indicating option 66 is not defined or is not being followed correctly. It's a shame that unlike Microsoft, Apple has not included these common option controls in their server interface. We're hoping someone who has actually gotten this to work will see this and be able to clear up what Apple needs for input to make it actually work right.
Thanks for any help!

Hi, I am the author of the DHCP Option Code Utility and therefore the unofficial worldwide expert on Apple's DHCP Server
If you go to http://www.sustworks.com/site/prodipmxoverview.html you can download a copy of IPNetMonitorX which includes a feature to test DHCP option codes. For example, you could test option 66 on a different make of DHCP Server (one that works) to see what exactly it returns, and then do the same test against Apple's DHCP Server and see if it is returning exactly the same result. Obviously if it returns a different result there is a problem.
Note: IPNetmonitorX shows all DHCP option code results as decimal numbers (you need verbose logging turned on), you may therefore need to translate these to hex or ASCII values. One decimal number equals one hex number or one ASCII character.
I can tell you that using DHCP Option Code Utility to generate the values, Apple's DHCP server works fine for many users needing to do this to support VoIP phone systems which also need to advertise a TFTP server.
I have looked at your message and as far as I can see, your entry for Option67 is what I would believe to be correct. Obviously this field is not an Integer, nor is it an IP address, so using the String option is the only logical choice. For Option66, like your post, two choices spring to mind, the first being to use the IP address choice and the second the string choice. Again your examples are what I would use with my first choice being the IP address one.
However there is one thing I can mention that may (or may not) help. An IP address for humans is written as 146.186.126.9 that is four decimal integers between 0 and 255 each separated by a full stop, if we break this down we have the following decimal integers
146
186
126
9
in hexadecimal the above translates to
92
BA
7E
9
Now the way Apple's DHCP Server actually stores IP addresses (ignoring the encoding you see) is actually as four hexadecimal bytes so if you use my utility to encode
92 BA 7E 09
as hexadecimal, you will find it results in the identical krp+CQ== result. Now apart from giving you some background which may help if/when you use IPNetMonitorX to test DHCP server option codes, what this also allows you to consider is that it maybe that some systems want these bytes in a different order. This relates to 'little endian' vs. 'big endian' see http://www.cs.umass.edu/~verts/cs32/endian.html
I am somewhat doubtful of this, as all the VoIP systems I have dealt with use the same order equivalent to 146 186 126 9
If your able to use IPNetMonitorX to query FOG's own DHCP server and give me the result, I can see what difference it is doing.
Note: You should only have one DHCP server on a network at a time, so you should do this test on a standalone network or when you will not interfere with your live network.
Note: You need to stop and start the Apple DHCP server in Server Admin to get it to re-read /etc/bootpd.plist and use your new settings. You should therefore stop the DHCP server while editing the file.
UPDATE - NEWSFLASH
Just retested my own Mac OS X 10.6.4 DHCP Server which has four DHCP option codes defined which were previously working. When I tried adding a copy of your option66, even with supposedly my DHCP Server 'stopped' it kept overwriting the changes I made. It maybe your server is also almost immediately overwriting and losing your option codes. Try doing it in single user mode or even booting from another disk and of course double check your bootpd.plist still lists your option codes.

Use dhcp to point to tfpt server

Is anyone using the OS X server dhcp to point to a tftp server. I have been using the osx DHCP and it is working ok for the 'normal' computer network. I am adding IP telephony and I want to continue using the OS X DHCP if possible. From what I understand, when the IP phone connect to the DHCP server, they can be given the address information to the tftp server to download configuration files.
So the question is as stated... has anyone done this? or does anyone have a recommendation.
Ted

It is possible to do - you need to add the specific option numbers that the phone needs.
You have to get under the hood to do this, though - you can't do it through the GUI.
You need to edit /etc/bootpd.plist to add the options.
As man bootpd states:
DHCP options may also be specified using the naming convention:
dhcpoption_optioncode
replacing option_code with a numeric value in the range of 1 through 254. For example, to
specify option code 128, specify a property named dhcpoption128.
So, for example, if your phones use DHCP Option 150 for the TFTP server address, you'd add something like:
<pre class=command><key>dhcpoption150</key>
<string>192.168.2.3</string></pre>
Which adds DHCP Option 150 (tftp server) to the DHCP configuration that hands out the address 192.168.2.3.

DHCP Option Code Utility - the return

A long time ago I wrote a utility to make it easy for mere humans to generate the encoded values needed to define DHCP Option Codes for use with Apple's DHCP Server.
This utility was remarkably bug free and even as a 1.0 version worked with PowerPC and Intel Macs all the way from Mac OS X 10.4 to OS X 10.7.5 with zero reported bugs. It did however hit a problem with Mountain Lion 10.8 which I have finally got round to investigating and resolving. It turns out Apple made a change that broke the way my utility was using a standard routine.
I have also taken the opportunity to add built-in support for generating null-terminated strings since it has emerged that some uses of DHCP Option Codes requires this type of string, for example PXE boot servers using DHCP Option Code 67.
The new 1.1 version can be downloaded free from http://jelockwood.blogspot.co.uk/2013/06/dhcp-server-on-os-x-server.html

Nice work John. Thanks for sharing this with the world.
I was pretty shocked when 10.6 server didn't include the facility to do this without going through this...

Assigning IP configuration to AP using DHCP

The scenario is a WISP. I am using Upgraded 350 APs and 1230s.
I am successfully able to reserve and allocate IP addresses to the BVI interface using MAC addresses as a parameter.
However does anyone know how I can allocate the Default Gateway, Hostname and Snmp-server IP addresses ? Some exist as options in the Linux dhcpd that I am using (e.g. "option routers") but the APs are not learning these options.
Thanks

Cisco stated this may be " mostly the devices we configure to expand the network or the devices we use to give network access to the end users use Management IP address" best practice for the same will be using static IP. So, if, we use DHCP option 43 as a local DHCP server for the site, this DHCP protocol will be understood by the AP only. and it may be easy to understand and deploy.
And secondly if, the Centralized DHCP server is configured & reachable from any site will surely get IP. Note :- (as said best practice is not keeping MGNT VLAN in DHCP enabled.)

DHCP option 66 syntax

Having trouble getting Yealink IP phones that are issued a DHCP IP of 10.x to register with the PBX, which is at 192.168.3.200. I think the issue may be the option 66 that is set as a policy on the 10. scope. I am chasing a theory that the phones aren't
understanding where to look for provisioning. So my question: Is there a right and a wrong way to enter the string value for the option 66? Should there be quotation marks around the string value? At this point, I am entering the value like this:
http://192.168.3.200:5000/provisioning/<CustomFolderName>
Many thanks for any suggestions.

Hi,
According to your description, my understanding is that you use DHCP option 66 to configure the IP phone(Yealink).
Since the option is used to configure the IP phone, then syntax of String value about DHCP option 66 is depended on the device.(For example, option 66 can be specified as TFTP server host name, reference link:
https://technet.microsoft.com/en-us/library/dd145324%28v=ws.10%29.aspx?f=255&MSPPError=-2147217396 )
Different devices have their own syntax. you may contact the IP phone's vendor/supporter for detailed information about this question.

Eve Wang

OfficeExtend with Aironet 600

Hello,
I need information about the Aironet 600 access point.
I got a customer who want to deploy a guest WLAN on branch office with an authentication with a captive portal that is centralized. I would like to use the OfficeExtend functionnality with Aironet 600 Acces point & WLC 5508 or 2504 to centralize the traffic from all access points on the controller.
On those branch offices, there were a few "free access desktops" that need a copper link. I want those devices to be also authenticated by captive portal, so I want to connect them on the four 10/100 port of the access point. But it seems that we can only use one port as "corporate remote LAN", the threee others are just for "home LAN". Is it correct ?
Is there any solution to configure the four ports as remote LAN interface ?
Thanks a lot for your help

Hi, I'd actually go after HREAP instead of Office Extend. OE is designed for a home user, so you can plug in a phone, or one machine.
HREAP will give you centralized wireless for the guest with the webauth page, and can drop the local traffic to the wire as well.
For the wired guest, I would recommend using 802.1x with fallback to guest. Look here
http://www.cisco.com/en/US/docs/ios/12_4t/12_4t11/ht_8021x.html
This allows the port to be put in a "Guest VLAN" that you can then direct to a authpage. This would require a tertiary device for the wired guests.
it may be more than you are really looking for, but IMO is the best answer to the situation.
HTH,

SPA122 - How to turn off "DHCP Option To Use" in the Provisioning tab using the XML configuration file?

As default, SPA122 and SPA112 have DHCP Options 66, 160, 159 and 150 turned on.
Our pre-provisioning process includes adding our default profile rule to our provisioning server for the device to pull its configuration files once the device has been added to an account.
However, it seems like some customers have had problems with the device downloading the definite configuration file and manually turning off option Option 66 in the provisioning tab in the device solves this issue.
Is there any option we could add to our pre-provisioning file so that it removes 66 from the "DHCP Option to Use" field in the provisioning tab?
Please advise...

Thanks Dan,
I didn't know the dhcp server could serve different options to different classes of clients, I'll have to look that up!
Moises
so if your provisioning file has this line below (this is from a spa5xx config I had in my temp folder, so use the line from your provisioning file, or use the SPC tool to create a new default config for that device type)
<DH<DHCP_Option_To_Use group="Provisioning/Configuration_Profile">66,160,159,150,60,43,125</DHCP_Option_To_Use>
change it to
<DH<DHCP_Option_To_Use group="Provisioning/Configuration_Profile">160,159,150,60,43,125</DHCP_Option_To_Use>
Hope it helps,

Low cost router with DHCP option 66

I am trying to find the lowest cost Cisco router with option 66. I use the router in conjunction with spa50x phones and need to be able to have them config at boot up.
I was using the srp521. It was suggested to use the isa550, but that just got an EOL. Do any of the RV routers support it, I did not find it on a rv110 and I know its not on the rv042. It seems to me that this is a functionality that should be on a router aimed at a small business.
Sage

Dear Sage,
Thank you for reaching the Small Business Support Community.
Unfortunately none of the Small Business routers were intended to provide DHCP option 66 for IP Phones configuration via TFTF server. I suggest you to look for a enterprise device for that matter, like an ASA for example, and you can also inquire about a low cost option from their community support forum.
My job role in Cisco, among several, is to identify business opportunities and product enhancements for the Small Business products so I am definitely going to suggest this option 66 feature for future firmware releases.
Please do not hesitate to reach me back if there is anything I may assist you with in the meantime.
Kind regards,

Pass Thru DHCP with Aironet 1231G

We have 12 - AP-1231G access points in our warehouse with 2 SSID's, both on different VLAN's. We would like to set one of the VLAN/SSID 's to use DHCP from a windows DHCP server.
Is this possible to do with option 43 or is that only for lightweight AP's ?

Also, I am seeing the cmd "ip dhcp relay information trusted" on some forums - is this also required ?

I'm hooked up to the ethernet using DHCP with manual address. It's running (green) but my internet (Safari, messenger, email) doesn't work! Help!

I'm running an iMac with Mountain Lion. Not only do we do accounting work on this computer with AccountEdge, but the computer functions as a server to another computer in a different state.
Anyway, I set a static IP address (Using DHCP with manual address) on it (to allow for a VPN to the computer in the different state) and it is connected (green dot) - meaning that the other computer in the different state can connect to us via that ethernet line - but for some reason Safari, Messanger, and Apple Email won't work.
But if I switch a dynamic IP (DHCP auto), I can use the internet (Safari, messanger, email), but the computer in the different state can't connect to this computer.
How can I fix this so that the computer in the different state can connect to this computer and that the internet (Safari, messanger, and email) can work at the same time?
Much thanks!

No but if they are using a VPN Tunnel for the connection that restricts all internet traffic over the tunnel. Which means you can't use that same computer to broswe the internet or connect to other computers or devices on your LAN.
I'd need to see the actual setup, router and the IP addresses you are using.
Networking and remote networking is fairly easy when you are in front of the systems you are working on. Doing it over the internet on a forum is almost impossible. Tha is why I suggested you get local help, like the person that originally set it up.

Using DHCP with a cFP-20XX across a different subnet

I have a cFP-2010 that will work great when set up with a static IP or DHCP as long as it is on the same subnet. If I set it for DHCP then move it to a different subnet, MAX can no longer find it. Do I have to use a static IP when going across subnets, or is there something I'm missing?
Thanks,
Steve

Selmore,
Not 100% sure this will work for FieldPoint controllers, but for some
other NI controllers (e.g. CompactRIO) if you give a name to the
controller in MAX and set it to use DHCP, then when its IP address is
assigned by the DHCP server its name is registered as a DNS name. That
means you can use that name to communicate to it from a different
subnet. By using ping commands you should be able to demonstrate if
this works for FieldPoint or not; I believe it should.
Hope my answer is clear enough and helps.

What is the use for CREATING VIEW WITH CHECK OPTION?

Dear Legends,
I have a doubt
What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.
A: Enforcing constraints at DB level.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???
Please clear my doubt's Legends
Lots of Thanks....

Hi, Karthick,

... What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..Most views are created and used for convenience. A view is a saved query. If the same operations are often done, then it can be very convenient to code those operations once, in a view, and refer to the view rather than explicitly doing those operations.
Sometimes, views are created and used for security reasons. For example, you many want to allow some users to see only certain rows or certain columns of a table.
Views are necessary for INSTEAD OF triggers.
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.The reason is integrity, not necessarily referential integrity. The CHECK option applies only when DML is done through the view. It prohibits certain changes. For example, if a user can't see certain rows through a view, the CHECK option keeps the user from creating such rows.
A: Enforcing constraints at DB level.I'm not sure what you mean. Please give an example.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??No. Using CHECK OPTION, you can do some inserts and updates, but not others. The columns involved may or may not have constraints in either case.
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???If you try to violate a constraint, you'll get an error. That happens in views with or without the CHECK OPTION, and also in tables.
