Cisco phone not getting ip address

Hi all ,
Cisco 2950 switch
Phone and dhcp server are in the same default vlan .PC's are getting ip address from dhcp server but not the phone
Thanks

Hi
I can see the mac address has registered on the switch . And i have tried couple of phones , result was same .
Then i did run a packet sniffing using wireshark .
I could see dhcp discover from the phone and offer from the server a couple of times .
i am attaching the dhcp offer part from the wireshark .
And i saw one error also
Error part

Phones not getting IP address via DHCP server on same VLAN

Hello....we have a new series of Cisco SF-200s and one new Cisco SF-300. All switches are operating in layer 2 mode currently. Let's say for all intents and purposes, all ports are in VLAN1....pretty much default setup. There is a fiber backbone between uplink ports...and it is working correctly it appears.
There is a DHCP server allocating addresses 192.168.0.60 thru 192.168.0.79. Subnet mask is 255.255.255.0.
PCs and laptops successfully receive an IP address and can access things.....such as surfing the internet. Tested that from multiple switches....all seems to work just fine.
However, it seems that some newly purchased phones (Digium models) simply will not acquire an IP address like the PCs and laptops do.
Pretty broad question....but just wondering.
Thanks!

Hi Greg,
Might be interesting to goto the following sections of the GUI disable the discovery protocols;
1. Administration>Discovery -LLDP >properties
2. Administration>Discovery -CDP >Management interface
3 Smartports >Properties > Admministrative Auto Smartports is disabled.
the switches are real smart and may pre-empt what you are trying to achieve.

Can't get ipv6 address assigned correctly.

I use NetworkManager and dhclient for auto-configuration but it has some weird problems.
When I boot up my laptop, I only have chance to get access to ipv6 network, when I fail, I tried to delete the connection in Network Management Settings, and then added a new profile, disable and then enable the network again. Sometimes it works well, but sometimes it failed to auto-config.
If I use the command:
$ ip -6 rout
then I'll get the following message:
unreachable fe80::/64 dev lo proto kernel metric 256 error -101
fe80::/64 dev wlan0 proto kernel metric 256
default via fe80::2e0:2ff:fe54:59 dev wlan0 proto static metric 1
every time the default gateway is configured well, sometimes the address the address is missed , and if I do the following:
$ ping6 -I wlan0 -c 4 fe80::2e0:2ff:fe54:59
It responses normally.
PING fe80::2e0:2ff:fe54:59(fe80::2e0:2ff:fe54:59) from fe80::1034:56ff:fe78:9124 wlan0: 56 data bytes

^C
--- ipv6.google.com ping statistics ---
11 packets transmitted, 0 received, 100% packet loss, time 10008ms
response nothing!
Then I switch into Windows 7, if something like above happened, then I managed to set the MAC address to a random value such as 12-34-56-78-91-23, soon, the problem will be corrected, I'll get a new ipv6 address assigned by DHCPv6 server. If I switch back to arch, set the MAC address in NetworkManager, it didn't have function at most time, and the ipv6 address even won't change!
Can anyone help me with this problem?
by the way, I never get ipv6 address when I use dhcpcd.

Just in case you are wondering where your post has been gone: The moderators board received this message from you:
I dont need tunnel to access to ipv6, My univ use dual-stack to get both ipv4 and v6 work around all campus.
This is because you inadvertently used the "Report" link. But don't worry this happens rather often.
Just cause I caught the glimpse of re-blabla, and mistaken it as reply

Guest users not getting IP address

I am setting up Cisco wireless along with ISE 1.3 for guest wireless. The client is going to use the self-registration portal for guest wireless users. I followed this Cisco doc to configure the self-registration portal:
http://www.cisco.com/c/en/us/support/docs/security/identity-services-engine/118742-configure-ise-00.html
I tested this in my home lab and everything works fine. However, at the client users are not getting IP addresses from the DHCP server. This is the same DHCP server that is used for corporate wireless and if you connect that SSID, you get an IP address. I have looked what I configured at home and the client and everything looks the same. In the back of my mind, I feel something is missing, but I can't figure out what it is.
Edit: Not sure if this makes a difference or not, but they are using a Nexus 5K for their core switch and it hosts the SVI for this network.
Let me know what information you need and I will post it.
TIA,
Dan

Hello,
Some verifications below :
Did you verify if DHCP Proxy is enabled in wlc's wlan interface ? Case DHCP proxy is disabled, did you verify if the ip helper address is enabled in Nexus SVI ?
DHCP Scope is enabled in the DHCP Server or is enabled in the WLC ?
Verify if Trunk in the switch is enabled correctly passing all VLANs to WLANs ?
Verify if ACL to redirect configured in the WLC is allowing DHCP Server and DHCP Client to client receive IP Address and ports 8443 to Cisco ISE and DNS to resolve some address and get access to ISE Portal ?
The scenario is Local Switching or Central Switching ?

DHCP via Hyper-V VM, Server2012r2 Hyper-V host, clients not getting IP address

You have to authorize a dhcp server as Britv8 says. That's the only way it'll start dishing out leases. That's standard for Windows DHCP server in an AD Domain.
Also there's 0 reason to mention Hyper-V here. The whole point of virtualization is to do hardware level abstraction.

I recently encountered this. Setup:
Initial setup of the system was at a different location from its final destination, with different network equipment (switches) between the two. No teaming is involved, however.
Set up the system at its final destination, with DHCP via a Hyper-V VM (Server2012r2), Server2012r2 Hyper-V host, physical clients on the lan were not getting IP address.
The physical server box has a 4-port Intel Gigabit ethernet card.
I moved the setup (Hyper-V Virtual Switch manager) so that the interface for the DHCP server VM was isntead using one of two built-in Broadcom adapters.
While this topic seemed promising,
http://community.spiceworks.com/topic/251317-hyper-v-vm-not-leasing-ip-s-dhcp
unfortunately, "fiddling about" was not what I was looking for as possible solution.

Cisco ISE 1.2, Clients not getting IP address in closed mode

Hello, I am running closed mode on my switchports. I have an issue where some clients come in in the morning, try to login, and will not get network access. I see that this is because they do not get an IP address. I am using MAB for authentication currently. They appear to MAB correctly and get Authorized in ISE, but they do not get an IP. Therefore, they also do not get the DACL of permit ANY. It's like the port gets de-authenticated during the night. Usually when the machine is rebooted it will come up with an IP address. Here is my switchport config...
switchport access vlan 32
switchport mode access
switchport voice vlan 64
logging event link-status
authentication event fail action next-method

Bluetooth PAN not getting IP Address (WM5/Samsung Blackjack)

I have a clean Leopard 10.5 install on a MacBook Pro and when connecting to the phone with Bluetooth PAN, an IP Address is not being assigned. I am using a Samsung Blackjack on AT&T with Windows Mobile 5.
I have verified that that Tiger 10.4.10 on the same system, clean install, works as expected and will connect and receive an IP address.
Steps...
1) Pair phone with system
2) On Phone, launch "Internet Sharing"
a) PC Connection should be set to "Bluetooth PAN"
b) Select "Connect"
3) On MacBook Pro, from Bluetooth Menu, select <nameofphone> --> "Connect to Network"
4) Open System Preferences --> Network
5) Notice that "Bluetooth PAN" service is active, but not getting an IP Address
Not sure how to file a bug against Leopard, but hope this will go to the right folks.
Thanks

The Bluetooth PAN is missing from the Network Interfaces.
I had a feeling it was the version of Leopard I was using cause when I tether my PPC phone to my Windows XP machine over Bluetooth it works fine. I used to use my PPC on my Macbook 10.5 when I first got it and loved it. But then I upgraded, sadly. I first experienced this problem when I upgraded my Macbook to 10.5.4. However I recently got another Macbook and I formatted it and put OS X Leopard 10.5 base install on it and it works with it! Why am I now not feeling urged to do any more Apple Updates?
I noticed that with 10.5 you have the choice to add "Bluetooth PAN" and on the the 10.5.4 Apple has removed this option all together! (sounds like a downgrade more than an update...removing a potential Network Interface to use yikes!) The only option in 10.5.4 you have is "Bluetooth" (the one where you have to enter Telephone number, Account Name, Password, the Bluetooth logo) and no Bluetooth PAN...
Here are my available Network devices on my Macbook 10.5 :
Bluetooth PAN
FireWire
Ethernet
Bluetooth
VPN
PPPoE
6 to 4
Here are my available Network devices on my Macbook 10.5.4 :
FireWire

Bluetooth
VPN

See anything missing? So even if I wanted to delete my Existing Bluetooth PAN (which doesn't even work right now anyway) profile I couldn't recreate it because it is not in the list of Network Interfaces! What gives Apple? AT&T got any hands in this?

Advising record (ADV - HSBC form) in DME file could not get email address

Dear all,
I have problems with DME file that Advising record could not get email that is maintained in vendor master data.
Standard communication methods in vendor master data must be Emails.
We use exit module to get this email for below fields:
Email chnl se. flag
Email address
T-code DMEE -> Advising record
(Attributes tab: Mapping procedures is Exit module.
Source tab: value was entered for Exit function)
We test once and got the expected result: email shown on DME file, in advising record.
However, as I rechecked recently, we have no email shown (though Constant value 'ADV' shown).
The form is active by the way.
I do not know if I miss anything in configuration.
Please advise.
Thank you very much.
Rgds,
Linh

Hello Linh,
Did you manage to resolve this. I'm facing the same problem, not able to get the email address.
Can you please provide the function module you used.
Thanks,

AP not getting ip address assigned.

Hi all,
I have a problem with my AIR-AP1041N-E-K9, i do not seem to get an ip-address assigned after a reset to factory defaults.
I do see the AP with CDP:
Device-ID: ap
Advertisement version: 2
Platform: cisco AIR-AP1041N-E-K9
Capabilities: TransBridge IGMP
Interface: gi5, Port ID (outgoing port): GigabitEthernet0
Holdtime: 163
Version: Cisco IOS Software, C1040 Software (C1140-K9W7-M), Version 12.4(25d)JA1, RELEASE SOFTWARE (fc1)
Technical Support:
http://www.cisco.com/techsupport
Copyright
Duplex: full
Power drawn: 15000 milliwatts
SysObjectID: 0.0
Addresses:
unknown addres
So that should mean that layer 2 connectivity is fine.
I have the AP connected to a cisco SG300 switch,and assigned switchport trunk allowed vlan's: 1,3,4,8.
Can someone help me?
Regards,
Menno

I also noticed that when i connect to the AP via console-cable, i can see the AP boot up in the console session, but then i do not get a login prompt, but it seems like the AP is responding; if i shutdown the interconnecting link between the switch and the AP, i do see log messages appearing in the console-connection.
I have tried to debug on the Switch, but i need a password, so i can debug, which i do not have.,

Hi, thanks for your reply,
I'm should be getting my ip via DHCP(as i believed that this is the way that the AP searches for an ip, when it has no config yet). The DHCP-server is configured on a cisco 871 router that is connected to the switch, as i found no option to configure it on my switch, which is in layer 3 mode. The DHCP-pool is assigned to the vlan(native) 1 address-range(in this case 192.168.0.x/24). I also have configured a range for my workstations, and here i do get Ip-addresses assigned.
The AP does not connect to a Wireless controller. Also i have checked my inter-vlan routing on my switch, and i have connectivity to all vlans, so i believe my AP should have connectivity to the DHCP-server configured on the router.
Ping-test from switch shows no issues:

Wifi clients not getting IP addresses

Hello Experts,
I have a Cisco 1140 AP, and using express setup I have cnofigured a IP address to it. This AP is connected to our public network and is configured with a public ip address. We want the guest users to connect to Wifi and gain access to Internet.
While the users connect to Wifi, I find their laptops getting IP address in series 169.x.x.x due to which they are unable to get to internet.
Can somebody guide to what all configuration required so that laptops would get ip address?
Thanks
Arvind

Hello George,
I do not have any DHCP server, I want the AP to allocate IP addresses to wifi clients.
Anshul,
Is there any way the AP distribute the IP addresses? I want to have the AP act as an DHCP server and allocate IP address of wifi clients.
If this is not possible in this AP model 1142N, any other Cisco AP model available, which can act as DHCP server?
My requirement basically is:
The AP should allocate IP in the range 192.168.x.x and I would connect the AP to the public network. The wifi clients should be able to get to Internet.
Please suggest any other model in Cisco which should meet my requirement.
Thanks
Arvind

Not getting IP address

My father's old iMac G3 slot loading system, running 10.2.3 experienced a power company power outage and restoration of power yesterday. It was connected to a DSL modem and all was working ok. Afterwards the DSL modem didn't work so the telco is sending a replacement. In the mean time I took the iMac home with me and cabled it to a router/DSL setup used by my iMac 24" and my wife's Gateway. The iMac boots up and spends a longish time in the Network startup phase and when done does not have an IP address from the DHCP server in the router. Other computers connected to this router get an IP address immediately so it's something in the iMac.
I can ping localhost (127.1.0.0) ok but cannot ping the router (192.168.1.1).
Is there anyway to test the iMac ethernet NIC to see if the power problem effected it?
Would doing an OS 10.2 reinstall be of any help? Any suggestions?

I seem to recall that Mac OS 10.2 had a problem with getting the DNS numbers.
What you need to do it is manually fill your numbers. You can still use dhcp and fill in the dns numbers.
BDAqua suggests in a post.
You can use OpenDNS for looking up web addresses.
Put these numbers in Network>TCP/IP>DNS Servers for a try...
208.67.222.222
208.67.220.220
https://www.opendns.com/homenetwork/start/device/apple-osx-tiger
(Please note that you do not need to a joint open DNS to use it.)
http://discussions.apple.com/message.jspa?messageID=5908432#5908432
Hear is the the full story.
Seems like you are not getting the DNS address or addresses.
apple > system preferences > network
Double click on network connection you are using.
Pick the TCP/IP tab.
Verify that you have a DNS Server. If you do not, look on your windows machine and see what the net address is. You can also pick using DHCF and still enter you DNS server address.
You can use
harddrive > applications > utilities > network utility
to diagnose the situation.
You can ping google.com. Result:

If pinging 17.254.3.183 works but pinging apple.com doesn't. You have a bad DNS Server address.
BDAqua suggests in a post.
You can use OpenDNS for looking up web addresses.
Put these numbers in Network>TCP/IP>DNS Servers for a try...

Analysis: If you cannot ping Goolge.com but you can ping 64.233.187.99, then you need to enter you dns address. For some reason Mac OS X sometimes doesn't set the dns. You can set it manually.
apple > system preferences > network
tcp/ip tab and enter address of dns servers
example 162.33.160.100
You will need to use a different number.

Cisco 891 not getting IP address with DHCP with latest IOS

Hi,
I have a few Cisco 891 routers that are configured as DHCP clients on the WAN interface.
For some reason when I boot the router with a late IOS, the router is not receiving an address.
It works just as expected with the older IOSes.
Any ideas of what changed?
This is how the interface is configured:
interface FastEthernet8
ip address dhcp
no ip redirects
no ip unreachables
no ip proxy-arp
duplex auto
speed auto
no cdp enable
This IOS does not work:
c890-universalk9-mz.154-3.M2.bin
While these do work:
c890-universalk9-mz.150-1.M7.bin
c890-universalk9-mz.151-2.T2.bin
c890-universalk9-mz.152-1.T1.bin
Doing a "show ip interface brief" shows that FastEthernet8 is unassigned with the affected IOS.
With the older IOSes there is an IP address.
I had to downgrade two routers due to this issue, and did not have plenty of time to troubleshoot.
Both of the routers are connected to DSL from the same ISP...
Anyone seen anything like this before?

Add another one to the list.
I have a MacBookPro3,1 that connects to WIFI no problem. It used to connect to ethernet when I originally bought it, however I've been using WIFI exclusively for the past 2 years.
Recently I had a need to connect via ethernet and it wouldn't work at home (apple airport router). I next tried connecting via ethernet at a friends house using a linksys WRT54G, no dice either. I have the computer in the lab today (University Network) and I get the same error. 3 different locations, 3 different routers, all same problem. It used to connect to home and university networks ethernet right away.
IP address assigned is 169.xxx.xxx.xxx - subnet - 255.255.0.0
no other info. It's showing up as connecting to the network, but unable to communicate with DHCP. It does work if I enter all of the information in manually.
At first I thought I had messed something up in networking preferences as I tend to play around with things alot. However I did a complete system format, and fresh install of OSX Lion and I still have the same problem, without any of my meddling around to confuse things.
What gives?

Cisco 3502I Not getting ip address

I just deployed 2 brand new 3502I access points. Ap's are connected to a PoE module on a 4507. Ap's are powering up. The 4507 is configured to hand out ip addresses to the ap's. When I run 'sh cdp nei det', I can see the ap's but they do not have an ip address assignment. Another weird thing is in the output of the command, each ap has two entries. One entry shows gigabit0 and the other gigabit0.1. I have never seen this before. I dont know if this in some way is why the ap's are not getting an ip address. I have 40 other 3502I from 2 yrs ago and no problem. The IOS of the new ap's is 15.2. Anyone have an idea to what may be happening? TIA

I will use the cisco 3750 PoE for further testing. It is close by my office and the cable run is under 200 ft. I used this same switch and port to configure the other 40 3502i ap's. Below is the output of the show power inline fa1/0/12:

DHCP: Some clients not getting IP address

Recently setup a new DHCP server on Mac OS X Server 10.5.8 running on an Xserve. We migrated from a Linux server.
The Xserve was originally just a file server. So the only services currently running are: AFP, DHCP, NFS, and SMB. No additional software is running.
The DHCP server ran just fine for the first couple weeks. But then we found some computers just stopped getting IP addresses from the DHCP server. Some were new computers introduced to the network. Some were laptops that had left and come back. However, the DHCP server is definitely still giving out IP addresses and renewing them for most new and existing computers. There have been five computers that have not gotten IP addresses so far, and that had been the case both on the wireless and on a wired connection. Two were PC's, one running Windows 7 and one running Windows XP with Lenovo's ThinkVantage software. The other three were different models of MacBook Pros.
For those five computers, we managed to get them working in two ways. One, we can select to use DHCP with a manual address. When we do that, it manages to pick up all the other information from the DHCP server like DNS and gateway. The second thing we can do is configure the DHCP server to supply a static IP address by providing it with the MAC address of these machines. When we do that, the computers receive the IP address from the DHCP server.
So I guess you could say the problem I'm experiencing is for a few computers the DHCP server seems to only be able to provide static addresses, but not dynamic ones with a lease time.
I have logging set to the highest for the DHCP server. Below is the first thing I noticed that keeps showing up. Sometimes it shows a different MAC address than the one below. None of the afflicted computers have that MAC address, though. I have not seen any other errors in the logs for the DHCP server.
