SG300 and RVS4000 DHCP problems

We recently deployed SG300-28 to replace an old 3Com switch.
The setup:
RVS400 router and all workstations and server are plugged into the SG300 switch.
The problem:
Windows 7 workstations are unable to obtain IP addresses from the server which is also plugged into the switch.
If however, we plug in the worstations into the 4 port switch on the back of the RVS4000 (the router), they get IPs from the server no problem.
This worked just fine with the old 3Com switch so we filed it under the Small Business Switches category.
Any comments/tips appreciated! Thanks in advance!

Pavol,
Please make sure the SG300 switch is running latest firmware 1.1.2.0 , also this is new code so please factory reset the switch after the upgrade. If you need assistance in upgrading please call Cisco Small Business Support Center @ 1-866-606-1866
After the upgrade please repost how these devices are connected and the configuration of your RVS4000 & SG300 series switch. Are you using RVS4000 for your DHCP server?
Also make sure your RVS4000 is running latest firmware as well.

WRE54G and WAP54G DHCP Problem

Hi,
Please can someone help me.
Current setup:-
Cisco ASA 5505 with DHCP Server enabled on the inside interface.
Linksys WAP54G cabled directly into the above interface on the Cisco ASA.
Linksys WRE54G with a wireless connection to the above access point using the same SSID and Channel.
When connecting my laptop to the linksys access point, the laptop obtains an IP address allocated from the Cisco ASA and works perfectly.
When adding the WRE range extender into the mix and connecting my laptop via the extender the laptop fails to obtain an IP address. The extender is connecting to the AP ok, it has 2 blue lights and i get a strong signal.
I have carried out packet captures on both my laptop and the inside interface of the CISCO ASA. The capture on my laptop shows DHCP discovery packets leaving my wireless interface, however, i receive no acknowledgement. when i run the same capture on the Cisco ASA i see the discovery packet hit the interface and a subsequent dhcp offer packet leave the interface, however, the offer packet does not reach the laptop when connecting via the extender.
Can anyone kindly offer any advise that doesnt involve throwing the extender in the bin!!?
Thanks

The WRE54G is connected after the WAP.
The router's IP is 10.10.10.254 and is configured to allocate DHCP addresses within this range.
The AP's management IP is 10.10.10.1 and the gateway is 10.10.10.254 (router address).
The Extender's management IP is 10.10.10.2 and the gateway is 10.10.10.254 (router address).
When connecting to the wireless network via the AP, it connects and receives an address.
When connecting to the wireless network via the extender, it connects but does not receive a DHCP address. Signal is strong and the extender shows both blue lights.

Cisco SG300 and LLDP with Yealink Phones.

I am currently trying to setup a Cisco SG300 switch with a hosted VoIP solution using the SG300's at the customer's premise. The Yealink phones I am not able to get them to pull an IP address and believe the problem is related to LLDP. We also use Polycom phones and they work just fine. Here is the configuration that I am currently using ( I have tried several different configurations and none of them work with the Yealinks. Any help would be greatly appreciated.

How to resolve DHCP problem in Oracle for Cent OS

Hi everyone,
I want to install Oracle 10g on my new linux os CentOS. At very first step of system check, it warns me about having DHCP enabled and to use some static IP insted.
I have already done loads of installation on my windows box so I know how to deal with DHCP by using Microsoft Loopback Adapter.
But I dont know if there is any Loopback adapter available for Linux ? I have tried already to google but it seems that its really difficult to find the correct installation methods because most of "How tos" just ignore the fact that , web interface of EM won't work well with DHCP ( as far as i know :D ).
So, is there any work around for this DHCP problem ? I mean linux version of microsoft loopback adapter !!! ... Also do I need to say that , its my laptop and I use it on various networks including starbucks and DD ;) ... so I guess , I can't go for configuring static ip for my physical card. my knowledge for linux is a bit primitive so it will be really appreciated if you can provide me step by step instructions.
BTW, regardless of warning i have installed Oracle 10g, and as i had expected .... Web Interface of EM gave me an age old error ( web page not found ) when I restarted my laptop... which is because of DHCP.
Thanks in advance for any help
Peace,
Jack

Thank you guys for your advice. I really appreciate it.
But this does not solve my problem. I dont know weather you guys know or not , CentOS is EXACTLY same as RHEL other then "support" thing. So I dont see any reason to switch from CentOS to RHEL. Another reason is , I have already installed CentOS on my separate partition , so I dont want to go to through all of that again :D .
And even if i think to change to OEL( i have downloaded it already ) or RHEL , problem still exists ... " DHCP " ... how do i deal with it ??
for my friend damorgan,
a fixed IP address is preferable but if you need DHCP for some reason just do the install, build your database, and then modify the listener.ora and tnsnames.ora to point to 127.0.0.1 for the host. , I know I need fixed IP, but if I am installing it on my laptop and just for study purpose, Its really not useful to setup static IP and as i wrote in OP, life of student is very adventurous and we never stay at one place right ? so, its not possible to have static IP for me ( unless i use it with VMWare or something like that ) .... now question is, what is this 127.0.0.1 ip you are talking about ? Do i need to add it into HOST file ? A little brief explanation will be helpful here :) ... this stuff is damn easy with windows and i am sure that linux should have have work around of DHCP. I am writing LINUX , instead of going in to specific flavor because i think the solution will be same only the method will change, right ? .
I also looked at the link David posted here , (to be honest , I have not gone through all OSes setup help ) , I can not find even a line mentioning about DHCP Problem. May be I am missing something , David can you point me exact link (if there is any) ?
Any more suggestions guys ?
Peace

IP device tracking and idle timer problem

Hi,
We are deploying 802.1X in our network and have encountered problem with a type of payment terminal.
The problem is that the terminal do not 'speak' to the network after the first initial DHCP request, the terminal waits for incoming packets from a counter to start the payment process. After the idle-time the MAC is flushed from the switch and the port is not authorized any more.
To solve this we set 'authentication control-direction in' on the port and use 'ip device tracking' to keep the client on the network, ip device tracking sends an arp request every 30 seconds to clients.
Our ISE is sending Radius:Idle-Timeout = 300 and the timer start to count down when the client is authenticated.
In Wireshark, I can see that the ARP request is going out and the ARP reply coming back in but this does not update the inactivity timer for the client. So after 5 minutes the port is gone, and there is no way to get the port up again from the network. Traffic from the client brings up the network.
This looks like a bug to me, anyone seen this, or a similar behaviour?
Running:
ISE 1.2p6
IOS 12.2(55)SE6
From Trustsec 1.99 Wired 802.1X Deployment Guide:
Tip Enable IP Device Tracking with inactivity timers to keep quiet endpoints connected. When IP Device Tracking is enabled, the switch periodically sends ARP probes to endpoints in the IP Device Tracking table (which is initially populated by DHCP requests or ARP from the end point). As long as the endpoint is connected and responds to these probes, the inactivity timer is not triggered and the endpoint is not inadvertently removed from the network.

WLC Internal and External DHCP

I am currently using the Internal DHCP component within my 5508 Controller with software version 7.0.166.0. This seems to be working fine as the Vlan Routed interface connected to it via the Dynamic Trunk Port is functioning as l have the ip-helper command setup on this specific vlan interface..
My issue now is that we have a isolated ADSL Network which is configured off our Core 6513 but just as a Layer 2 Vlan so no traffic can be routed to other vlans.
With our new WIFI environment which consists of the 5508 Controller and numerous 3502 AP's we wont to utilize this ADSL vlan with our new WIFI environment.. This ADSL Vlan has a dedicated Linksys Router which is currently running DHCP and assigning addresses to clients at the moment..
What l want to do is configure the 5508 controller to use this ADSL vlan aswell but to also keep using the Linksys Router aswell for DHCP..
I have setup a new dynamic interface and added the ADSL Vlan ID to the Trunk port of the 5508 and also setup its own SSID. But for some reason l cannot get both the internal and External DHCP servers to work at the same time ? If l enable DHCP Proxy option on the 5508 the internal DHCP server works and when l disable DHCP Proxy the ADSL Vlan DHCP works through the 5508 but not the internal DHCP Server ??
Can l get both the internal and external DHCP servers to work in harmony or should l be focusing on using one method over the other ?

Hey Scott l have just tried configuring another scope for the L2 Vlan but it doesn't seem to be working when l add the ip address of the management interface which is the internal DHCP Server to the dynamic interface of this adsl network l have setup l dont seem to get a ip address within this scope ?
I am just wandering seeing it is just a L2 vlan without a routed interface would this be the problem and would need to set this up with the "ip helper-address" of the management interface ?

%DOT11-7-AUTH_FAILED: Station c023.4921.2100 Authentication failed%Unknown DHCP problem.. No allocation possible

Hi All,

Anybody know the reason for this behavior ?
Thanks,

Hi Charith,
It's looks like AP goes into Standalone mode due to it cannot reach your WLC. In flexconnect when it cannot reach WLC, it will go into standalone mode without rebooting AP. (in local mode AP will reboot unless it can find a WLC)
Can you check your AP has reahability to your WLC all the time ? Where the DHCP configured for users ?

WRT54g router DHCP problems (I think)

I just got a wrt54g wireless router for my organization hooked it up and started having problems. I set the router to use DHCP and *tried* to set the “Maximum Number of DHCP Users:” to 15 and clicked “Save Settings” but when I went back to that screen it would be back at the default (5), I have since tried to change it many more times and no matter what number I pick (2-230) it still shows up as 5. Anyway. 1st I connected my XP notebook and was able to access the internet (specifying that my computer obtain the IP address automatically) Next I connected my colleague’s vista notebook and he could access the internet. (specifying that his computer obtain the IP address automatically) Next I connected another colleague’s xp desktop (specifying that my computer obtain the IP address automatically) *Next* I tried another colleague’s XP notebook computer and started having problems. I specified that it should obtain the IP address automatically but it would not and kept getting a 169.254.x.x address instead of one like 192.168.1.x (it also keeps showing a subnet mask different from the one I specified on the router). I went back to my notebook (which had been working fine) and discovered that now (without my making any changes to my notebook) I am having the same problem. I am now having the above problem (computers not receiving addresses automatically) with all but one or two computers (the vista notebook continues to work). Someone on usenet suggested I try putting in an IP address manually so I did and it worked but #1 I need more than 5 computers to be attached at one time (the router refuses to accept any number higher than 5 [though I can specify *less* than 5, it will for example remember 4 and 3]) #2 The router should be assigning IP addresses to all the computers, I shouldn’t have to be putting in the addresses manually.

Did you try to flash/reflash the routers firmware? Try that and reset the factory default settings and cycle the power. Then reconfigure the router and let us know if it continues to do that.

WRT54G (v5) DHCP problem (MAC, APPLE, MAC OS) -- How to fix it

Ok, so I just got some instructions from Linksys support and apparently definitely got rid of the DHCP problem. Here they are:
Please reset the router before and after the upgrade.
To reset the router (make sure that the modem is disconnected when doing a reset):
1. Locate the reset button of the router at the back panel.
2. Hold the reset button for 30 seconds using a pen or a paper clip.
3. Release the reset button and unplug the power adapter of the router.

Hi, Malcolm:
Thanks for the post.
No, my new Mac Pro system does not have USB port on the Keyboard, cause I've opted for Apple's wireless blue tooth mouse and keyboard.
I do have 2 USB ports on the Apple's 23" LCD display, and Two USB ports on front side and two available USB ports on the back of the Mac itself.
During the Thanksgiving long weekend, I think I might accidentally singled out the cause of my problem.
I have my HP printer and one multi-card reader constantly pluged into the two USB ports at the back of my Mac, and always tried to use the front side USB ports for the 1GB USB Pen Drives, and that's where the problem lays!
When I unplug the Multi Card Reader from the back USB port, and suddenly all USB ports on my Mac works just fine with the Pen Drives!!!
So, for now, I plug the Multi Card Reader in one the the front USB port, and the rest of the USB ports on the Mac work with Pen Drives flawlessly, it seems that I sloved my problem for the time being...
As for those two USB ports on the back of my 23" Apple Display, They can not take my USB Pen Drives, as you've mentioned that it does not have enough power for the USB Pen Drives.

SG300-20 - Configure DHCP on VLAN interface

I have been reading the various related discussions on the SG300 and SG500 switches regarding setting up VLAN's and DHCP on those VLAN's. For whatever reason I have been unable to even get this simple task to work.
First thing I did was to update my firmware and boot version as follows:
SW version    1.3.7.18 ( date 12-Jan-2014 time 18:02:59 )
Boot version    1.3.5.06 ( date 21-Jul-2013 time 15:12:10 )
HW version    V02
When I reloaded the SG300 after the SW/Boot updates the startup config was wiped out and I had to setup my switch from scratch. The intent is to have two VLAN's:
VLAN 1: all devices, servers, etc.
VLAN 2: basic subnet that hands out DHCP addresses
The SG300-20 is connected to an Asus RT-AC66U router on the 192.168.1.x subnet and provides internal network access and WiFi access (router IP address is 192.168.1.1 and is default gateway). All that works with no issues. So my task is simply to create VLAN 2 on 192.168.2.x subnet and use DHCP to allocate addresses. I have spent many hours on this and I still can't get it to work. When I connect a laptop to the port (GI8) assigned to VLAN 2, I end up getting some wonky 169.254.x.x address. I certainly thought something this "easy" wouldn't be that hard to setup, but apparently I was wrong.
The SG300 is running in L3 mode as shown in my running-config below.
Does anyone happen to see something that might be preventing my laptop client from recieving IP addresses from the VLAN 2 DHCP interface that are not in the 192.168.2.x subnet?
Any ideas / suggestions would be greatly appreciated!
Here's my running-config:

Tom,
Thanks ... I followed the steps you outlined and it worked! The only difference being that I have an Asus RT-AC66U router and the there is no "enable multiple subnet" option. So, I just followed your instructions on creating the static routes in the RT-AC66U and everything worked. The DHCP addresses were correct and I had internet connectivity when I plugged a laptop into the gi8 port.
I did make one tweak to the Network Pools screen as follows:
My DHCP configuration for gi8 on VLAN 2 now looks like:
ip dhcp server
ip dhcp pool network InternalWAN
address low 192.168.2.1 high 192.168.2.99 255.255.255.0
lease infinite
domain-name MYSTIC
default-router 192.168.2.254
dns-server 8.8.8.8
Previously I had followed your advice in the article "Need help configuring SG300-10 switch" and had setup everything using CLI. However, I didn't think about needing the static routes. So, I think it was probably setup correctly beforehand but had no chance to work because the routes were not setup.
Thanks very much for your help!

Airport Extreme and Time Capsule problems

I have had an Airport Extreme 802.11g, version 5.7 for several years and have some problems that is get stuck now and then, so I have to restart it. I have tried to upgrade software, but cannot find anything appropriate. Assume 7.5 is a software version, but where and how to upgrade?
I got another problem when I bought a Time Capsule. It interferes with my Siemens Gigaset wireless phone. I have tried to change channel etc, but it does not seem to help. Any tips?
The two problems are not related, as I had the first problem before I got the Time Capsule.
Tor

v5.7 is the latest firmware for your AEB 802.11g.
v7.3.2 is the latest firmware for the TC.
You should probably do these simple maintenance tasks:
Simple Maintenance Tasks:
1. Repair Permissions - /Applications/Utilities/Disk Utility.app. Start Disk Utility, select your HD and click on Repair Permissions. When finished, quit Disk Utility and then restart your computer.
2. Reset PRAM - hold down Option-Command-P-R keys when starting until you hear the startup chime a 2nd time.
3. Safe Mode Startup - hold down the Shift-key at startup until you see the login screen. When logged-in, then go to System Preferences/Network/AirPort
- click on the 'Network Name:' roll-button, select 'Join Other Network...', enter 'Network Name and select the security type you are using, and finally, enter your Password and click 'Join'.
- click on 'Advanced', TCP/IP and confirm that 'Configure IPv4:' is set to 'Using DHCP', click 'OK'.
- click the 'Apply' button and exit System Preferences.
Make sure you separate the AirPort Base Station and the wireless phone by as large a distance as you can.
You could enact Interference Robustness, but it will reduce the range of your AirPort base station:
1. Open AirPort Utility, select the AirPort Base Station (main) and click on 'Manual Setup'.
2. Click on 'Wireless' tab and click 'Wireless Options'.
3. Tick 'Use interference robustness, click 'Done', and click 'Update'.
4. Wait for ABS to restart. Restart your computer and test.

WRT54G V6 DHCP Problem

I have a WRT54G V6
I am use WPA 2 with AES
and useing MAC Filering
i have 1.02.2 7/02/2007 Firmware for the WRT54G V6
- i think it may be the Firmware

The firmware is the most current one on the site. There are no other options than that. Anyway what kind of DHCP problem are you having? Is your laptop getting "limited or no connectivity" when you try to connect wirelessly to the network?
Don't use AES. Most cards are only compatible with TKIP.
What kind of Wireless MAC Filter are you using "Prevent" or "Permit Only"

RG54GS Internet DHCP Problem

I have this problem :
- Whenever my cable-modem restarts himself or loose connection for awhile MSI RG54GS cannot obtain new DHCP lease ...
Goes like this .... all is working fine .....
Cable modem goes offline (for some reason) , MSI obtains from modem a 192.168.1.x IP and stops trying to renew IP .
In system log whenever my cable modem give MSI a ip like this , there are no new DHCP renew tries . I have to go to web-admin page , to internet zone and choose DHCP client again ....
- Any ideas ???

if there's a possibility to set up on cable modem fixed ip, then set it up and...then set it up on router..

How do I Help Apple Care Stop Warring with Each Other and Fix the Problem with My iPhone that They Acknowledge Creating?

How Do I Help Apple US & Apple Europe Stop Warring With Each Other And Fix The Problem They Created?
PROBLEM
Apple will not replace, as promised, the iPhone 5 (A1429 GSM model) that they gave me in London, UK, with an iPhone 5 (A1429 CDMA model).
BACKGROUND
My iPhone 5 (A1429 CDMA model) was purchased this year in September on an existing Verizon Wireless (VZW) line using an upgrade. The purchase took place in California and the product was picked up using Apple Personal Pickup through the Cerritos Apple Retail Store. I will refer to this phone at my "original" phone.
The original phone was taken into the Apple Store Regent Street in London, England, UK on November 15, 2012. The reason for this visit was that my original phone's camera would not focus.
The Apple Store Regent Street verified there was a hardware problem but was unable to replace the part.
The Apple Store Regent Street had me call the US AppleCare. At first they denied support, but then a supervisor, name can be provided upon request, approved the replacement of my original phone with an iPhone 5 (A1429 GSM model) as a temporary solution until I got back in the US. And approved that the GSM model would be replaced with a CDMA model when I came back to the US. I will refer to the GSM model as the "replacement". They gave me the case number --------.
The Apple Store Regent Street gave me the replacement and took the original. The first replacement did not work for reasons I do not understand. They switched out the replacement several times until they got one that worked on the T-Mobile nano SIM card that I had purchased in England, UK. Please refer to the repair IDs below to track the progression of phones given to me at the Apple Store Regent Street:
Repair ID ----------- (Nov 15)
Repair ID ----------- (Nov 16)
Repair ID ----------- (Nov 16)
The following case number was either created in the UK or France between November 15 to November 24. Case number -----------
On November 19, 2012, I went to France and purchased an Orange nano SIM card. The phone would not activate like the first two repair IDs above.
On November 24, 2012, I went to the Apple Store Les Quatre Temps. The Genius told me that my CDMA phone should not have been replaced with a GSM model in the UK and that this was clearly Apple's fault. They had me call the AppleCare UK.
My issue was escalated to a tier 2 UK AppleCare agent. His contact information can be provided upon request. He gave me the case number -----------.
The UK tier 2 agent became upset when he heard that I was calling from France and that the France Apple Store or France AppleCare were not helping me. He told me that my CDMA phone should not have been replaced with a GSM model in the UK and that this was clearly Apple's fault.
The UK tier 2 agent said he was working with engineers to resolve my problem and would call me back the next day on November 25, 2012.
While at the Apple Store Les Quatre Temps, a Genius switched the phone given to from repair ID ----------- with a new one that worked with the French nano SIM card.
Also, while at the Apple Store Les Quatre Temps, I initiated a call with AppleCare US to get assistance because it seems that AppleCare UK was more upset that France was not addressing the issue rather than helping me. I have email correspondance with the AppleCare US representative.
A Genius at the Apple Store Les Quatre Temps switched the replacement with a new GSM model that worked on the French SIM card but would not work if restored, received a software update, or had the SIM card changed. This is the same temporary solution I received from the Apple Store Regent Street in the UK.
By this point, I had spent between 12-14 hours in Apple Store or on the phone with an AppleCare representative.
Upon arriving in the US, I went to my local Apple Store Brea Mall to have the replacement switched with a CDMA model. They could not support me. He told me that my CDMA phone should not have been replaced with a GSM model in the UK and that this was clearly Apple's fault. My instructions were to call AppleCare US again.
My call with AppleCare US was escalated to a Senior Advisor, name can be provided upon request, and they gave me the case number -----------. After being on the phone with him for over an hour, his instructions were to call the Apple Store Regent Street and tell them to review my latest notes. They were to process a refund for a full retail priced iPhone 5 64BG black onto my credit card so that I could use that money to buy a new iPhone 5 64GB black at the Apple Store Brea Mall to reoslve the problem.
The Apple Store Regent Street did not process my refund. He, name can be provided upon request, told me that the AppleCare US did not do a good job reviewing my case, that they were incapable of getting to the bottom of it like they were, and instructed me to call AppleCare US and tell them to review this case number and this repair id. I asked if he read the notes from the AppleCare US Senior Advisor and he would not confirm nor deny. When I offered to give him the case number he accepted but it seemed like would do no good. Our call was disconnected. When I tried calling back the stores automated system was turned on and I could not get back through.
Now I have the full retail price of an iPhone 5 64GB black CDMA on my credit card and Apple will not process the refund as they said they would.
I've, at this point, spent between 14-16 hours at Apple Stores or on the phone with AppleCare representatives, and still do not have the problem resolved.
SOLUTION
AppleCare US and AppleCare Europe need to resolve their internal family issues without further impacting their customers.
Apple is to process a refund to my credit card for the cost of a full retail priced iPhone 5 64GB black.
DESIRED OUTCOMES
I have an iPhone 5 (A1429 CDMA model) that works in the US on VZW as it did before I received the replacement phone in the UK.
Apple covers the cost of the solution because I did not create the problem.
Apple resolves their internal issue without costing me more time, energy, or money.
This becomes a case study for AppleCare so that future customers are not impacted like I have been by their support system.
Does anyone have recommendations for me?
Thank you!
<Edited by Host>

Thanks, but I've been on the phone with AppleCare US (where I am and live) and AppleCare UK. They continue bouncing me back and forth without helping resolve the problem.
Perhaps someones knows how to further escalate the issue at Apple?

Remote Control and Remote View Problem

Hi,
I work at a High School running Netware 6.0 SP5 and Zen works 4.01 ir7.
Remote Control and Remote View works great but I noticed one problem.
We have a logo of the school that is forced down on to the desktop when a
user logs in through group policies. This logo works perfect for the
desktop wall paper and loads every time a user logs in.
When I Remote Control or Remote View a computer the users desktop wall
paper turns from the logo being forced down through group policies to the
desktop to a blue desktop wall paper.
I would prefer the desktop wall paper staying the schools logo when I
Remote Control or Remote View because if the desktop wall paper changes to
the blue color I mentioned above when I Remote Control or Remote View the
users computer, they will know that someone is taking over their computer
which sometimes we dont want them knowing.
We have Windows 98SE computer running Novell Client 3.4 and we have some
computers running Windows XP Professional SP1 and Windows XP Professional
SP2 both running Novell Client 4.91 SP2.
The Remote Control and Remote View problem of the desktop wall paper
changing on the users computer occurs on all operating systems mentioned
above.
Is there a solution to my above problem? When Remote Controlling and
Remote Viewing someone's computer I don't want the desktop wall paper to
change.
Thanks!
