VOIP and dhcp pool

We just upgraded the CallManager and new voips. I have noticed that we are running out of ip's. We setup a second pool, but are unable to register any phones on the new/different vlan (453). What am I missing?
      The config on NTP/DHCP server is as follows:
      Ip dhcp smart-relay
      No ip dhcp use vrf connected
      Ip dhcp excluded-address xxx.xx.253.129 xxx.xx.253.135

DNS in DHCP Pool (Internal DNS issue)

I know that we can setup multiple DNS server under DHCP pool. But I like to make sure the order.
I have multiple branch offices.
Let us say that Branch 1 office has a router with 10.30.1.1 as default gateway.
Our internal DNS is 10.0.0.1 and 10.0.0.2 as Pri and Sec.
My order of DNS server is like below.
1. gateway
2. internal DNS
3. public DNS provided by ISP
I saw couple of issues that when I put internal DNS first. Particular situation is when IPsec is not working, users could not access internet through domain name because they had internal DNS which is not reachable.
But, when gateway is first order, I am not sure whether user are able to access internal website because gateway DNS doesn't have internal DNS records.
So, my question is that. what should be the best order for DNS setup under DHCP among default gateway, internal DNS and public DNS? Our current setup doesn't have even gateway address, it only has internal DNS addresses only.
ip dhcp pool ccp-pool1
network 10.30.1.0 255.255.255.0
domain-name test.org
default-router 10.30.1.1
netbios-name-server 10.30.1.1
dns-server 10.30.1.1 10.0.0.1 10.0.0.2 24.25.5.60

Thank you, Richard.
You are right. when I setup router IP for DNS server in DHCP pool. it did not work.
Let me ask regarding external DNS forwarding.
I like to know the process of exteranl DNS.
User --> Internal website --> OK with internal DNS
User --> External website --> Internal DNS forwarding to External DNS
We have our own external DNS (ns), in this case, if external DNS (ns) is down, every branch users are not able to resolve any external IP because internal DNS can't get reply from external DNS?
2nd question)
IPsec is split-tunneled, but in this case, every DNS request goes internal DNS which is located in HQ and goes back through IPsec? Usually Split tunnel doesn't go internet traffic through IPsec but internet directly.
3rd Question)
what is for ip name-server x.x.x.x when I setup ip name-server 8.8.8.8 and I tried to ping 8.8.8.8 from router, it didn't work. Am i missing something?

OES11 SP2 - Linux File System and NSS Pools & Volumes

Planning to install our first OES11 SP2 server into an existing tree - the
idea is to run this new OES11 server virtualized on VMware ESXi 5.5
The existing tree has two physical NW6.5SP8 servers running eDirectory
Version 8.7.3.10b (NDS Version 10554.64). One of the existing Netware
servers is used for DHCP/DNS, File Sharing from three NSS volumes and
Groupwise 7.0.4 whilst the second server is used for FTP services and
eDirectory redundancy. Ultimately the plan is to have two virtualized OES11
SP2 server with one for file sharing and the other for making the move from
GW7 to GW2012. And we're planning to stick with NSS for file sharing on the
new OES11 SP2 server.
I've come across a couple of posts for earlier versions of OES which
recommended not to put the Linux Native OS File System and NSS storage
pools/volumes on the same hard drive. Apparently the advice was a result of
needing to allow EVMS to manage the drive which could be problemmatic.
I've read the OES11 documentation which says that "The Enterprise Volume
Management System (EVMS) has been deprecated in SLES 11, and is also
deprecated in OES 11. Novell Linux Volume Manager (NLVM) replaces EVMS for
managing NetWare partitions under Novell Storage Services (NSS) pools."
So I'm wondering if there is still a compelling requirement to keep the
Linux Native File System and NSS pools/volumes on separate hard drives or
can they both now safely co-exist on the same drive without causing
headaches or gotchas for the future?
Neil

Hi Willem,
Many thanks for the further reply.
So we can just use the VMWare setup to "split" the one physical drive into
two virtual drives (one for the OS and the second for the pools).
And I've seen posts in other forums about the need for a decent battery
backed cache module for the P410i controller so I'll make sure we get one
(probably 512Mb module + battery).
Can I ask what is the advantage of configuring each VM's virtual disk to run
on it's own virtual SCSI adapter (by setting disk1 to scsi 0:0, disk2 to
scsi 1:0, and so on)?
Cheers,
Neil

DHCP pool to large. I want to shrink it.

Hi. So I have a DHCP Pool from say x.x.x.1 to x.x.x.200 buti want to reduce it to allow more static IP addresses at the top end so I want for example to change it to x.x.x.1 to x.x.x.170 to do this do I need to make a not of all the settings and delete the pool entirely and recreate the new pool, or is there which I would prefer to do, some way to shrink the pool, without blowing it away.
I'm paranoid and hate the idea of deleting it and creating a new pool, just in case. :)
Thanks

Along with Anders comments...
I'm not sure, but with NetWare one could adjust begin and end ranges for the DHCP pool... no? (Can't check). That option was gone with Linux (eDir integrated) DHCP services, but can still be done "under water".
If it's just the range and no real subnet changes... you can also edit the range using iManager or ConsoleOne (by looking at the values of the subnet pool in the "other" tab). Then reload the service. You should give the PC's some time (depending on lease time and how ofter PC's get rebooted) to get an assignment that's inside the new set range before handing out the addresses for static assignment.
As added note:
The export/import will work just as well, but a word of warning: with the Linux DHCP version you can lose certain info like class definitions and other little stuff. So it's always good to make note of the settings before doing that.
Cheers,
Willem

AP and IP pool allocation.

Hi all,
could someone explain me how
and in which phase AP allocate IP address
from DHCP pool for authenticated client?
We have many APs configured with WPA and radius authent. but I dont know where it is said that AP should alocate IP address
from concrete DHCP pool?
AP allocates IP addresses from pool in which it has its own IP address?
BR.
jl

If you are using Autonomous APs, they do not allocate IPs by default. You can enable DHCP on them, but I prefer using the servers you already have. If the WLAN is on it's own vlan, you just need to specify an IP Helper address on the router interface telling it what DHCP server to get IPs from.
If you are using LWAPP APs, inside the controller you need to define the DHCP server address when you create the controller interface. Again, the controller can be the DHCP server, but I prefer using an existing DHCP server if one exists.
If you post the type of APs and more information about your network setup, I can provide more specifics for you.

WLC 5508 Flexconnect dhcp request landing on wrong vlan/dhcp pool

Hi,
We've recently setup our 5508 to work with Flexconnect. The 5508's run on 8.0.100, they are setup redundant. On the remote site we've setup a local dhcp pool for the various WLAN's/VLAN's. The AP's have registered with the WLC succesfully.
We then setup the flexconnect groups, added the ap's and configured 1 vlan mapping to it's corresponding wlan id. Alsio setup the wlan, made it so it's using flexconnect, bound it to the interface which will allow it to reach the local dhcp machine.
User can see the SSID, can login using the password, but they are awarded an ip addres from a different dhcp pool, meant for antoher vlan than the bonding in the flexconnect group is indicating.
When I check the local dhcp pool for bindings on the mac address of a machine I can see multiple bindings. At 1 point I had 3 bindings in different pools, 1 on the native vlan for the AP, 1 on the vlan it should have and 1 on another vlan which wasn't configured anywhere in the flexconnect setup.
Does anybody have a clue how and why this is happening?

Just to add to Salma... All your AP's in FlexConnect are most likely connected to a trunk port. Make sure the native Vlan is defined and the vlan's are allowed on the trunk port. Then you need to verify that the AP's native Vlan and WLAN to Vlan mappings are correct. Seems like you might have some AP's that are not defined properly and that's why users that connect to a WLAN is getting in the wrong subnet.

DHCP pools for LWAP's with multiple models

I have 2 different AP models (1130's & 1140's) for which I want to create a DHCP pool on a core layer 3 switch with an Option 43 pointing to the Wireless LAN Controller. In conjunction with the Option 43 entry however, I need to specify the AP type as an ASCII string in the Option 60 parameter. Problem is, how can this be done for multiple ASCII strings; ie. multiple AP models? The DHCP pool option 60 entry only allows for one string and you can only enter one option 60 command per DHCP pool. Surely it is common to have more than one AP model and that this can be done without having to resort to multiple DHCP pools (one for every model)?
Can anyone shed some light on this for me please? Would be much apprciated as I've come up blank on CCO documentation!

I usually just stage the AP first to join a WLC and to make sure it works prior to installing it. Pllace it on the same submnet as the management and let it join and then set the primary, secondary and or tertiary. Then you can move it to any vlan you want. If you want to use DHCP Option or DNS, then you should know that if for example it is an RCVK IOS previous to capwap it will only do LWAPP. Once it joins to the WLC in LWAPP it takes a new IOS the unit will do CAPWAP.
As an example 1140 have an RCVK IOS that only run CAPWAP, so it should only do CAPWAP:
CISCO-LWAPP-CONTROLLER and CISCO-CAPWAP-CONTROLLER
Create two A records both pointing to the same controller if you want to use DNS.
DHCP Option 43:
DHCP Option 43 is limited to one access point type per DHCP pool. You must configure a separate DHCP pool for each access point type.

CUT
The customer here wanted to set an option 43 and 60 to dhcp adresses in this local pool.
What I am wondering is if the option command I have set works like the excluded addresses command does. Aka setting the option in range from .100 to .199?
I also added the ip dhcp relay information option to the config.
Other suggestions for this?
Haven't really set up many dhcp pools with option before. The customer's goal is to get autodiscovery going on their end.
My apologies if this question is posted in the wrong community, I found something with the word "LAN" and went for it.

Can not create or modify DHCP pool in UC560

I can't create new or modify existing DHCP pool inside our UC560 by using CCA 3.2.3 version: Configurate->Routing->DHCP server. I always get error "invalid DHCP pool range. The default gateway IP address 192.168.2.1 must be within the range of the address excluded from the DHCP pool."
I check my DHCP exclude tab: I already have start IP: 192.168.2.1 and End IP 192.168.2.10.
I would like to know solution to modify my current DHCP pool or I can add new DHCP pool by using CCA. If I have to use CLI, please let me know how to do it.
Thanks

Something with my configuration that CCA can't modify it.. It have to go through CLI

Maximum no of DHCP pools on a WLC

Hi, I want to create a separate ip pool pool based on the WLAN, what the maximum no of DHCP pools allowed on a WLC.

Internal DHCP is only for small networks and lab use.
We do not recommend to use it for any large deployment, please use an external DHCP server instead.
This is documented:
The internal DHCP server was introduced initially for branch offices where an external DHCP server is not available. It is designed to support a small wireless network with less than ten APs that are on the same subnet.
It is not a full-blown general purpose DHCP server. It only supports limited functionality and will not scale in a larger deployment.
http://www.cisco.com/c/en/us/support/docs/wireless/4400-series-wireless-lan-controllers/110865-dhcp-wlc.html#Internal-DHCP
While you can configure multiple DHCP pools and it can work fine for some time, in my experience I have seen this internal DHCP server stop leasing IP address with 2 or 3 class C networks configured.
My recommendation, use an external DHCP server.

Cannot make DHCP reservation out of the DHCP pool

Hello,
I foud a bug in the router:
I am using network 172.16.20.0 with subnet 255.255.252.0 wich means i can use IP adresses from 172.16.20.1 until 172.16.23.254.
When i setup my DHCP server on the router (from 172.16.20.1 to 172.16.20.100) i cannot make a DHCP reservation outside of this DHCP pool.
Is there a workaround or am i doing something wrong?
Thanks in advance.

This is normal networking standards. When a DHCP pool is set up, only reservations work with in this pool. You can set up static IPs out side this pool if needed. Which is recommended for printer, NAS and low priority devices.

IPoE BNG and DHCP on the ASR9K

Hi,
can some one tell me if this is possible.
I have a bundle Interface -using ambiguous VLANS:
interface Bundle-Ether100.1
vrf customers_1
ipv4 unnumbered lo2
ipv4 point-to-point
arp learning disable
service-policy type control subscriber UFB_DHCP
ipsubscriber ipv4 l2-connected
initiator dhcp
encapsulation ambiguous dot1q any second-dot1q any
I have two loopback interfaces:
interface lo2
vrf customers_1
ipv4 address 100.64.0.1 255.255.128.0
interface lo3
vrf customers_1
ipv4 address 200.200.200.1 255.255.254.0
I am authenticating users using option82 remote-id, and DHCP for address allocation. I want to use RADIUS to send back attributes, to set the users template, and, somehow set the dhcp giaddr so that the user gets an address from the correct pool.
ie. put the user into this template:
dynamic-template
type ipsubscriber CUSTOMER
vrf customers_1
ipv4 unnumbered Loopback3
and have them then given an address in the lo3 (200.200.200.0) range. No matter what i do the dhcp giadd remains the address of the Bundle Interface.
I have tried all sorts of radius attributes:
Cisco-AVPair = 'subscriber:service-name=CUSTOMER'
Cisco-AVPair = 'subscriber:command=activate-service'
I have tried:
Cisco-AVPair= 'ipv4:ip-unnumbers=Loopback3'
Cisco-AVPair= 'subscriber:classname=lo192' - and creating a dhcp class to set giaddr
I get a "aaa_type invalid attribute, flags 0x21"
I am at a bit of loss, and am not sure if what I am wanting to do is even possible.
though if set the template statically via an onboard policy things seem to work, and my user gets an address from the correct loopback.
any help would be appreciated.
ta.

Cisco-AVPair = 'subscriber:sa=UFB_CUSTOMER' -> sets dynamic template

However..
the ip address range is from the loopback 2 address, (this is the loopback bound to the unbundled BNG interface)
My understanding is that the giaddr address should have been changed to the ip address of lo3, which is the loopback specified in the RADIUS attribute.

I tried changing the dynamic template to service rather than ipsubscriber, this did not make a difference. You make a reference to DHCP classname. I have defined a DHCP class, however do not know how to match or force the use of a particular class by using a RADIUS attribute.
Thanks,

Aironet 1140 AP's and DHCP

We have 6 aironet 1140's throughout the office I have them all configed as one ssid but I would like the DHCP to come from our Windows server. Right now I have set them up with ip dhcp pools. So what is the secret to get them to send dhcp requests to the Windows server?
Thanks

Nope...
All you have to do is configure ip helpder address on L3 device and remove the dhcp pool configuration from AP's. This will ensure that devices pick ip from your wondws dhcp scope.
Hope that helps.

DNS not resolving to new machines on network after increasing DHCP pool size

Hello,
I am having a very strange issue with connecting new machines to reach the internet.
We have a ASA 5505 which the previous tech configured the DHCP pool to 192.168.1.60 - 192.168.1.110
We ended up reaching our limit which I changed it to: 192.168.1.60 - 192.168.187
Then next day when I arrived to work, our DC was hung from windows updates. Once we got everything back up, every computer currently on the network can reach the internet/VPN tunnels etc. So (continuing with my day) I created a new server in a VM (Hyper-V)
I can ping everything internally (even the router) 192.168.1.1, but I cannot resolve DNS. I have configured a static IP, tried Dynamic IP.
I have looked for any ACL indicating to block outside the range of the old DHCP pool but no luck.
On my local maching I can ping the DNS addresses, but just not on the new server.
Can anyone point me in the right direction to where to look for this issue?

I ended up figuring out what the issue was.
Since it was in a Hyper-V VM. the hosting server had to be updated to SP1.
Once completed, and rebooted. The VM in question got an IP address.
