Advanced DHCP Configuration
Dear people,
I was glad to see that in 1.0.2.6 some tftpboot issues have been adressed. However I run into a problem.
I setup the Advanced DHCP with the tftp server ip (also tried hostname btw), configured the
DHCP Client Device vs. Configuration File Mapping Table. When I try to tftp boot any device, the devices search for the boot file not on the tftp server (192.168.1.100), but on the RV180 itself (192.168.1.1). I find this very confusing. Could it be that tftp function 66 isn't working as it should be, or could it be something in my local configuration? Are there any limitations I should know about?
Thanx!
Hi Samir,
Thanx for the reply.
I used to have a wrt54g as the default gateway in my network, tftpbooting just went fine, all my clients were able to connect to the tftpserver and load the designated files. I swapped the wrt54g with the rv180 (gigabit etc) assuming the information in the datasheet was based on real functionality. Unfortunately tftp on the rv180 was a diisapointment from the start. The first two firmware releases only accepted tabeling with .cfg files. Now, in release nr 3, the webui allows the mapping of other than .cfg files. Gladly I can map .0 and .bin files now. Clients doing tft-booting receive an ipadress and wait for 192.168.1.1 (rv180) to hand them the right files, ofcourse this never happends. I wonder what firmeware version will hold the fix to this problem. it could be that the rv180 has a hidden tftp-server, or maybe tftp-function 66 is just not working. Tftp-function 150 is also a next-server funtion, it is proprietary from Cisco itself. My clients and tftp-server are not familiar with this function, maybe the rv180 has trouble choosing 66 or 150?

Fix typo in error string for situations where there are advanced messaging configuration settings from LCDS used in the configuration files but no AdvancedMessagingSupport service. The error string said that there was no flex.messaging.services.AdvancedMessagingService registered but it is the flex.messaging.services.AdvancedMessagingSupport service that needs to be registered.

blazeds/trunk/qa/apps/qa-regress/testsuites/config/tests/messagingService/ReliableDestina tionWithNoAdvancedMessagingSupport/services-config.xmlHi,
Unfortunately I already tried all kinds of re-installs (the full list is in my original message). The only one remaining is the reinstall of Windows 8 itself, which I would really like to avoid.
What I find really strange is the time it takes for the above error message to appear. It's like one hour or even more (never measured exactly, I left the computer running).
What kind of a timeout is that? I would expect that, if ports are really used by some other application, I get the message in less than a minute (seconds, actually). To me this looks like the emulator itself for some reason believes there's a problem with
some port while in reality there isn't.
I'll eventually contact Microsoft Support, thanks for the suggestion.

How can I use Powershell to "Complete dhcp configuration" ?
I installed the DHCP Server feature with Powershell and now I'm wondering how to "Complete dhcp configuration" also with Powershell?
Here's what I did (example):
Install-WindowsFeature DHCP -IncludeManagementTools
Add-DhcpServerv4Scope -name "Corpnet" -StartRange 10.0.0.100 -EndRange 10.0.0.200
-SubnetMask 255.255.255.0
Set-DhcpServerv4OptionValue -DnsDomain corp.contoso.com -DnsServer 10.0.0.1
Add-DhcpServerInDC -DnsName dc1.corp.contoso.com
"Server Manager |> DHCP" now informs me that "Configuration required for DHCP Server at DC1" and by selecting "More" I can "Complete dhcp configuration". So, how do I complete the task with Powershell?

For a very belated answer, you need to set a registry value to tell it that the configuration has been completed.
Set-ItemProperty -Path HKLM:\SOFTWARE\Microsoft\ServerManager\Roles\12 -Name ConfigurationState -Value 2;

Windows 2008 DNS & DHCP configuration steps for 11gR2 GI install with GNS
Hi,
I have windows 2008 R2 server with DNS & DHCP services installed. I am planning to install 2 node RAC with GNS option.
The problem is i could not find any document to setup the windows 2008 DNS server for the below steps.
a. Configure GNS VIP : add a name resolution entry in a DNS for the GNS virtual IP address in the forward Lookup file.
gns-server IN A <virtual_IP>
where gns-server is the GNS virtual IP address given during grid installation.
b. Configure the GNS sub-domain delegation: add an entry in the DNS to establish DNS Lookup that directs the DNS resolution of a GNS subdomain to the cluster.
clusterdomain.example.com. NS gns-server.example.com.
where clusterdomain.example.com is the GNS subdomain (provided during grid installation) that you
delegate and gns-server.clustername.com resolves to GNS virtual IP address.
I am aware that this configuration steps has to be taken care by the System administrator. Here is what he tried and the results.
My SA was able to Configure GNS VIP in the DNS and the Nslookup works fine for this.
When he Configures the GNS sub-domain delegation the nslookup fails when trying to resolve the SCAN name.
Any step by step tutorial for this windows 2008 DNS & DHCP configuration for Oracle GNS setup would be highly appreciated.
Thanks,

Anchor Guest controller and DHCP configuration
I checked the cisco documentation about the DHCP configuration but I´m not 100%sure which DHCP server address I must use.
I used as example the scope 10.240.97.0/24 for our Guest Users. In this range are the DHCP scope and the Guest interface configured. For the management I used as example the range 10.240.96.0/24.Now I configured our Guest WLC and I insert on the Guest interface as Primary DHCP address the Guest interface address. After I applied I got the message I can´t use this DHCP address. Now I checked the cisco and found following description:
“If DHCP services are to be implemented locally on the anchor controller, populate the primary DHCP server field with the management IP address of the controller"
Means it now I must insert as the IP for the Primary DHCP Server on the Guest interface the IP from the management
Interface and the controller will then forward the traffic to the internal DHCP scope on the Guest subnet and wil sent it back ?
( DHCP proxy is on the Guest WLC enabled ) .
Thanks
AlFor Anchor you can use either internal or external dhcp server.
Means it now I must insert as the IP for the Primary DHCP Server on the Guest interface the IP from the management
Interface and the controller will then forward the traffic to the internal DHCP scope on the Guest subnet and wil sent it back ?
Yes. WLC forwards the unicast dhcp req to management ip for guest interface. All cpu generated traffic by default uses management interface as source address i.e., snmp, radius, ping...
Is your question whether you need routing between guest and management interface.
No, routing is not required in this case bcoz the interface residing on WLC's management. Also for proxy it uses the virtual ip address for dhcp instead of actual dhcp ip. And only wireless client can get ip from WLC's internal dhcp server.
If you're using dhcp proxy on wlc and having external dhcp server on different vlan then yes you need routing between the two vlans. -
Can anyone tell me how to change the DHCP configuration options - the same information found in dhclient.conf in linux/unix - under OSX? A corporate client of mine provides wireless internet at all their facilities, but no one with a Mac has ever been able to connect. The wireless connection comes up and is stable, but the Mac never receives an IP address. I am fairly certain they forward DHCP requests to a centralized server that handles multiple LAN segments. I suspect something in the format of the DHCP packet, perhaps one of the many options, is causing their router to drop the Mac's DHCP request packet. I have captured DHCP requests from OSX and Win2K using Ethereal, so I have some idea what options to try changing, but I need to know how to go about it. I've tried adding a dhclient.conf file, but OSX seems to ignore this.
Needless to say, this is not a simple question and I realize I'll be fiddling at low levels. However, I've tried everything there is to try with the control panel, command lines, etc. I generally have no problems getting WiFi to work across Mac and windoze whether at home, in hotel rooms, or at corporate locations, but this one really has me stumped. Any help is appreciated.How are you connecting to the wireless network? Is it a closed network with security, or an open network? There are a lot of different protocols in play with a wireless connection, particularly with Cisco equipment. It's possible Macs don't support one of the protocols where Windows does. There may be extra security such as DHCP client IDs, or using DHCP reservations only. There could be MAC address security setup on the wireless APs.
I would ask one of your PC buddies help you find an unused address. Set that manually and see if everything works. If it does you know you have a DHCP problem. If it doesn't there's a problem with the wireless connection -
Hi,
we have installed WDS server on windows server 2012. Our DHCP is a CISCO 2911 Router. what do we need to configure on the WDS and DHCP server for the clients to have a PXE boot.
Thanks in advance"If the local DHCP server is not a Microsoft DHCP server, we will have to manually configure the DHCP server to forward the request to the WDS server."
How will the clients ( laptops/desktops) do the PXE boot and pull the image from WDS server ?
"If you have any problem, please configure DHCP option 66 and 67." -- on which device do we need to configure this ?
Thanks -
Hi,
Below are the configurations of DHCP Server in 3550, it perfectly works fine & assigning the IP address across multiple VLAN's.now i wanted a setup in such a way that, i should not configure 3550 as DHCP Server, i wanted to make 2950 as DHCP Server, i mean we have got so many 2950 switchez, all switches are in same VLAN, but the PC's in every department are in different VLAN's. so i tried the option mentioned, but it doesn't work? where in do it in individual switch, it works, so how to proceed now.

switchport mode trunkHi,
in the *not wotking* 2950 example, the 2950 should provide IP addresses to which clients? Why is the DHCP server set to 10.1.1.1, when the Switch IP is 10.4.1.1?
Do you have IP connectivity to all the other switches?
A DHCP request from a PC is sent as a broadcast. When it reaches the DHCP server it will determine the proper pool from the interface it was received. So try to place the 3550 DHCP config completely into one of the 2950 switches. Also make sure not to have duplicate IPs.
In case direct broadcast access to the DHCP server is not possible you will need a DHCP proxy. This can be achieved by "ip helper-address 1.2.3.4".
Hope this helps -
Hi all,

and the BVI
interface BVI1
description Basic Virtual Interface
ip address A.B.C.D /24
no ip route-cache
the BVI interface is in the native Vlan of Data. My issue is that I want to have on subnet 192.168.1.0/24 for Data and another 192.168.2.0/24 for the voice
but the problem is that I always get dhcp info from the subnet where the BVI is.
Can anybody help me on that ?
I assume that the DHCP request is ?ade by the IP of the BVI (when helper activated) so this is why I always get an IP from the data pool where the BIV is into.
I started to think to some solution like create a BVI2 but this is a lost of IP
or directly assign ip from sub ethernet int and activate the helper.
What is the best and what do you think of that ?
Thanks in advance
MattYour problem is all your interfaces are using bridge group 1. change the bridge group number to match the corresponding VLAN and things should improve as long as the switch port is configured for trunking/.1Q support.
Suggestion initially configure the VLAN's using the WEB interface and then check the config and see the result.

Static vs. DHCP configuration: Arch-specific details
Hi,
I'm a recent Arch convert (after seven years of Slackware, Debian and CentOS). I have a few questions about details that I didn't quite get in the Wiki section.
1) static IP
The sample line in rc.conf is explicit enough, so this one is no problem. On the other hand, there are some diverging hints concerning the configuration in /etc/hosts. Let's say I configured a server with a static IP of 192.168.1.1/255·255.255.0. In that case, is it correct to have an /etc/hosts that looks like this?
127.0.0.1 localhost.localdomain localhost
192.168.1.1 buildbox.localdomain buildbox
Or is it:
127.0.0.1 localhost.localdomain buildbox.localdomain localhost buildbox
2) DHCP
If I configure my Ethernet interface with DHCP, what do I have to put in /etc/hosts? Only the localhost line?Yeah, you don't really need to inject anything into /etc/hosts
I'd say this is partially wrong. When I only keep the default /etc/hosts, I get a warning message when XFCE starts up: it complains that there's no hostname defined.
Finally, I'm using this configuration:
127.0.0.1 buildbox.local buildbox
127.0.0.1 localhost.local localhost
Note: The double 127.0.0.1 is only for better readability.
But I just notice something else, that puzzles me a bit. Here's what ifconfig returns, as expected:
[root@buildbox:~] # ifconfig
eth0 Link encap:Ethernet HWaddr 00:20:ED:B8:E8:EC
inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0

RX bytes:3470 (3.3 Kb) TX bytes:3470 (3.3 Kb)
And here's the network section of my /etc/rc.conf:
# DHCP: Set your interface to "dhcp" (eth0="dhcp")
# Wireless: See network profiles below
eth0="eth0 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255"
INTERFACES=(eth0)
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
# - prefix an entry in ROUTES with a ! to disable it
gateway="default gw 192.168.1.254"
ROUTES=(gateway)
What puzzles me: I didn't define anything localhost-like in rc.conf, and yet it's there. How comes?

ISG-BRAS DHCP Configuration.
Hi ,
We are deploying the ISG-BRAS for one of the SP client. The SP client is going to use ISG as DHCP server for internet clients.
As part of the implementation, I would like to know the suggestions for the below quires.
- How many concurrent session it can handle?. We want to use it for around 30K+ concurrent sessions.
- How many IP Pools will it supports?.We have around 200 small pools of different ranges.
- As we have the redundant setup so what will happen to the sessions and lease, if primary ISG goes down.
- Can we use HSRP virtual IP as a IP Helper IP(for DHCP relay routers) for a redundant solution.
- Static IP handling in ISG based on Remote-Id+Circuit-Id.
Attached the DHCP traffif flow of our implemention.
Regards

The error "Unable to manage defined hosts table" (cfg_wiz_invalid_host) appears to be due to permissions - do you have modify permission on /etc/hosts?
b)
It may be worth trying to configure DNS as the name service in dhcpsvc.conf(4) before starting the wizard (I seem to recall having to do this once before). e.g.
HOSTS_RESOURCE=dns
UPDATE_TIMEOUT=30
This may help isolate the problem

DHCP configuration for non-compliant clients
So your question isn't for a live situation, but because you are studying for a test?

that is , how to configure DHCP server to lease IP address to non-compliant client??
specifically for access to remediation servers
thank you..

DHCP configuration files on ML?
hello,
is it possible to configure the old settings on dhcp from my lion server?
in the bootpd.plist file aren't the settings from my static IP's with mac adress.
the server runs and give the right IP's to the client but i can not find the config files.
where are the config files??
thx for help/etc/bootpd.plist still remains the main config file for the DHCP server in Mountain Lion Server. It apparently still supports adding DHCP Option Codes to /etc/bootpd.plist (manually).
As Strontium90 says the definition of static DHCP address maps is normally stored in Open Directory and would therefore be editable using the Directory Utility. It is however apparently also possible to use the /etc/bootptab file to define DHCP static IP address mapping. Normally this file does not exist and in its absense Open Directory is used instead. However if you create this file and populate it, then it will be used instead of Open Directory.
The documentation for Lion and Mountain Lion Server is practically non-existent, I did however fine the following
https://developer.apple.com/library/mac/#documentation/Darwin/Reference/Manpages /man5/bootptab.5.html
and typing man bootptab in Terminal in Mountain Lion will probably show the same. -

I have to achieve the following task in LMS
Display of all devices on LMS IP telephony (as it support CDP) and Cameras (as it support SNMP)
Configuration of VLANS & Ports from LMS software, like if i click on port i should be able to change its vlan or creating of new vlans on core switch
Configuration of EVN from LMS, not sure if its supported but need any advices
Updating VLANS on LMS when created on core switch,
Live Graphs on LMS, want to know where i can configure this feature.
Help regarding this issue is highly appriciated.
Thanks in advance.
