• [wlc] secondary wlc in a 1:1, Ip dhcp pool redundancy

  Hello

  I will put up a high availability of 1:1 with 2 wlc 2504.

  I need to enter the ip address primary and backup controller and name to each AP.
  Unfortunately, we have a lot of AP and AP will more soon; it manually will take some time.

  I wonder if there is a way to give the secondary ip address to the ip dhcp pool? or any other stand-alone solution.

  Thank you very much

  For any additional consultation

  To quote one of the answers:
  The global primary and secondary come into play if there is no primary or secondary configured specifically in the AP. personally I've never used it however if you had only two controllers that would be ideal. I just see by specifying more granular level AP. personally I always use the HA tab for the ap as you never know how the deployment will evolve. You may fail aps to only one controller several controllers. You may need the HA failover priority. It is always useful to understand what will happen when your controllers fail and can become interesting if you have several controllers with several groups of AP and RF to profiles that you really need start controlling what ap's going where.

  As you can see, most of the Admins do not configure the Global setting.
  Just be patient in their configuration by AP XD

• RV325 DHCP pool limits

  Is it possible to have a larger than 50 ip addresses dhcp pool in RV325 (firmware 1.1.1.19)?

  Assuming that your using the RV325 as the DHCP server, Yes, you need to go into the configuration of the DHCP Server page and change the departure, arrival or the two IP addresses to make the pool as big or small as you want.

• Is it possible to assign the DHCP pool to a specific SSID?

  Hi experts,

  I wanted to know if it is possible to assign a DHCP pool to a specific SSID on the Cisco Aironet 1142. If so, what commands do I need to implement?

  Thanks in advance.

  concerning

  Fari

  We can directly assign the DHCP for the SSID pool, we can map the SSID to a VLAN and this subnet VLANS can be configured for the DHCP pool...

  If this client that connects to the SSID will hit him VLAN and then this VLAN the DHCP is reset...

  On the access point, you can configure the DHCP pool or even on the switch or L3 device or server...

• DNS issue when workstation has static IP

  Hello

  I created a SonicWall the other day, and I'm having a problem on 2 workstations. These two work stations have static IP addresses. Other workstations using the DHCP protocol. Those who use DHCP can access Internet without problem.

  Computers with static IP address can access the Internet, but only if they're ready to use the DNS servers of the ISP. If I put them to use the SonicWall as primary DNS, they can't get out to the Internet. Thus, if the SonicWall is 10.0.0.1 the following will not allow Internet access

  IP/subnet: 10.0.0.100/24

  Gateway: 10.0.0.1

  DNS1: 10.0.0.1

  DNS2: another value

  but change DNS1 to 24.92.226.11 (Time Warner DNS) will allow Internet access.

  Any thoughts?

  The SonicWALL cannot act as a DNS server. If you don't have internal DNS I suggest to use the public DNS as google 8.8.8.8.

• Remote access VPN Client to PIX, DNS issue

  Hi all.  I searched on this, but I can't find my answer.

  I set up a VPN connection to a PIX Firewall (running the version 8.0 (4)) for my business.  The VPN connection works correctly, in that I can connect to it using my software (v 5.0.02.0090) Cisco VPN Client and ping servers/resources internal IP address. However, if I try to ping by host name, it does not resolve to an IP address.  If I open a command prompt on my PC and type ipconfig/all, there are no DNS servers for my VPN, just for my normal Intel NIC adapter - I think I should have a DNS server listed under the map of VPN, right?  Here is the relevant (I think) for the VPN config lines:

  8.0 (4) version PIX

  domain xx.xx

  DNS lookup field inside

  DNS server-group DefaultDNS

  Server name 192.168.20.23

  domain xx.xx

  IP local pool vpnpoolIT 10.10.8.2 - 10.10.8.254 mask 255.255.255.0

  Crypto ipsec transform-set esp-3des esp-md5-hmac FirstSet

  Crypto-map dynamic dyn1 1jeu transform-set FirstSet

  Crypto-map dynamic dyn1 1 lifetime of security association set seconds 28800

  Crypto-map dynamic dyn1 kilobytes of life 1 set security-association 4608000

  crypto ISAKMP policy 1

  preshared authentication

  3des encryption

  md5 hash

  Group 2

  life 86400

  tunnel-group ITGroup type remote access

  tunnel-group ITGroup General attributes

  address vpnpoolIT pool

  Group-RADIUS authentication server

  tunnel-group ITGroup ipsec-attributes

  pre-shared-key *.

  Am I missing?  I can solve the DNS on the PIX itself requests.

  All the info I can find online is for an older version of the PIX software which says that I should enter the vpngroup dns- IP address of the server command, but this command is not available in my version of the software.

  Hello

  To set a DNS server to be injected into the VPN clients when they connect, you can do the following:

  This is the tunnel-group where lands the remote connection:

  tunnel-group ITGroup type remote access

  tunnel-group ITGroup General attributes

  address vpnpoolIT pool

  Group-RADIUS authentication server

  tunnel-group ITGroup ipsec-attributes

  pre-shared-key *.

  For example, create a group policy:

  internal VPN group policy
  attributes of VPN group policy

  DNS value--> x.x.x.x where x.x.x.x is the IP address of the DNS server

  Then, apply the group policy for the Group of tunnel:

  tunnel-group ITGroup General attributes

  Group Policy - by default-VPN

  It will be useful.

• DNS issue on the Windows Server-based host computer

  I encountered a problem which is probably easily solved - but I've been browsing the net for days already and cannot find a solution.

  First, I will describe my basic setting.

  I run a Windows Server 2003 host in a simple configuration of the House, connected to an ISP. I have my own domain name, which is hosted by another company. My local domain name is called "mydomain.local"; My overall domain name is called 'mydomain.eu '. I send a large number of specific services on my local server, using the settings for my domain name host. So my Windows Server is called orakel.mydomain.local; My Web page, which is hosted on the outside is www.mydomain.eu, but I use my local server for ftp access, so ftp.mydomain.eu is sent to my local IP address; my router forwards to orakel.mydomain.local and my ftp server on Windows Server handles the traffic. This Setup works very well and allows me to administer my internal and external DNS settings.

  My main server uses 192.168.0.1/255.255.255.0 and is also DHCP/DNS server for the rest of the network.

  As I plan to switch to Linux, I installed Vmware Workstation 7.1 on my server (orakel.mydomain.local). I created an image, add a static IP (192.168.0.50) in this image. The VM network adapter has filled and directed to my physical network adapter. I added an external debian record, achieved to my IP static, just like I did with my ftp, usenet etc - thus, debian.mydomein.eu is directed to my fixed address, that is passed (by my router) to the orakel.mydomain.local (192.168.0.1)

  And then I ran into problems. I want to access my image debian from the outside world and cannot get this to work.

  When I'm on-site talk, I use 192.168.0.50 to access my image. I added a DNS a record on my * local * (debian-> 192.168.0.50) DNS server, while debian.mydomain.local also works very well as long as I'm using my own local network.

  But I want to use debian.mydomain.eu, because it will allow me to access the image debian to other places as well. I can't find a way to achieve this. When I use debian.mydomain.eu, I get redirected to my router which redirects me to orakel.mydomain.local, but it ends there. I run Apache on both my windows server and in the image virtual debian, but I ended up always on my windows http server, not on my server debian.

  When I change my router settings to forward port 80 to 192.168.0.50, it works, of course - the virtual machine image works fine. But how do I get my windows to redirect some of the names of servers to virtual images? I would like to execute WEBDAV in a VM-image debian and keep my existing Windows-local http server running as well. Thus, redirect ports on the router clearly won't work, such as HTTP and Webdav to use port 80. I have been looking and trying to not solve or no this result. I * know * that virtual machines are used only to share physical resources for a number of Web sites, and that's just what I'm trying to accomplish!

  Where do I need to make adjustments? What is a VM settings somewhere, or should it be solved by the guest operating system DNS settings?

  Paul Kooistra

  Hello Paul,

  DNS only don't name resolution. So, given a name, which is the corresponding IP address known. What I understand, you want to have multiple servers in order to be accessible from the Internet for the same service (ie. http) using the standard ports and this is where your problem lies. Unless each of these servers are addressable landscape in terms of sound system you will not be able to do it without using a part of the trick of my previous post.

  Your ISP gives you more than one external IP address? If so, do you have a firewall that can handle more than 1 address NAT?

  Kind regards.

• EA6500 - DNS issue

  Devices connected to my EA6500 not connect to internet unless I put a DNS (8.8.8.8 for example) to each device. This problem occurs with or without wire. My iphones are the only devices that seem to get a DNS from the router. All other devices (DirecTv genius, Xbox 360, laptop, Lenovo, Sony Blu - Ray, AppleTV, nest the players) get a 192.168.1.1 in the DNS domain and does not connect until I put a different DNS.

  I tried to reset the modem, router. I have reset the router by default and reinstalled does not. Someone at - it suggestions?

  Comcast service 50/10

  SB6141 Cable Modem

  It is not a question of what DNS server I use. It has been more than one server DNS has been passed to my devices.

  I think I found the issue however. I'll post details later, but in a nutshell the DNS 1, 2, 3 fields don't were not filled in one of the configuration menus. I put some and my devices worked without manual entry on each device.

• Cisco Jabber for iPad released 9.2, dns issue

  Hello!

  Is there an administrator's guide for the new version of the iPad? I can only find one for version 9.1:

  http://www.Cisco.com/en/us/docs/voice_ip_comm/Jabber/iPad/9_1/Admin/JABP_BK_J3C828CB_00_jabber-for-iPad-Admin-9-1-1.html

  which does not describe the function of automatic discovery for the style connection "e-mail."

  I can see there are some research carried out:

  TXT? domain.com.
  SRV? _cuplogin._tcp.domain.com.
  SRV? _xmpp-client._tcp.domain.com.
  SRV? _cisco-phone-tftp._tcp.domain.com.
  SRV? _cisco-phone-http._tcp.domain.com.
  SRV? _sips._tcp.internal.domain.com.
  SRV? _sip._tcp.internal.domain.com.
  SRV? _sips._tcp.external.domain.com.
  SRV? _sip._tcp.external.domain.com.
  SRV? _ciscoedge._tcp.domain.com.
  SRV? _ciscowtp._tcp.domain.com.
  SRV? _ciscowtp._tcp.jabber.com.
  SRV? _ciscowtp._tcp.webex.com.
  

  It works fine for me if I put the _sips._tcp.external.domain.com. pointing to my vcse.

  One explanation could be useful, expecially did what research TXT.

  Hello Martin!

  I know that your question is a couple of weeks and I think since the Jabber for iPad team has posted the last administration guide which has been updated to version 9.2.  See the section 'Setup DNS SRV' as it could explain what you are looking for - I know not how this article differs from the previous guide...

  For the benefit of third parties who have Jabber for the iPad from the specific questions, please note that the community of Jabber Clients is available.

  HTH,

• Strange Cache DNS issue (maybe?)

  For the last two days, I was frustrated by my inability to set up a custom domain Outlook.com in 2013 Outlook on my computer, and then yesterday I finally realized that the issue is more precisely with my computer (by adding the domain to any other computer or at work is fine)

  The problem is that it seems to be something implemented caching on my computer. This has to do with a security for a Web site certificate that I participated in the test.
  I checked the store of certificates on this computer and there is nothing for that Web site.
  I also did the ipconfig/flushdns, does not
  And I stop each device on the network, including the cable modem / routers, but still the problem persists
  Any idea where I can look for something related to certificates or DNS which could be stored somewhere that I should delete / flush?
  Thank you...

• Login screen - DNS issue

  We seem to be affected by intermittent empty login screen on my company's website, but only for the microsoft login page, the login page Skype charges well.

  Loading Skype upward, you get this screen:

  

  And users choose 'Microsoft account '. They should then see this screen:

  

  Instead they get this:

  

  Inside, there is a warning message stating the following:

  "This page contains errors. Go back'

  The site uses OpenDNS to filter queries DNS for computers and politics is quite locked.

  On any affected PC, if:

  -Close Skype

  -Run the DNS settings to something like 8.8.8.8 (google DNS server)

  -Load Skype

  The login screen (image 2) loads normally. The user can connect and I can then folding the DNS settings on the OpenDNS server and there is no other problem.

  Which means that Skype is trying to communicate with a Microsoft/Skype server somewhere on the interent and because it is not on my whitelist OpenDNS it gets blocked and it fails as in Fig. 3.

  My question can someone tell me what is the server? I went through the OpenDNS logs and the white list a bunch of stuff from microsoft and other things related to the certificates, but still no luck.

  Evetually I took the suggestion of Techfreak and sniffed packets with wireshark. Was annoyed to discover that the root cause of the problem is strangely named sb.symcd.com.

  Some quick Google-fu led me to a page that said that this area should be on a whitelist for Lync facilities. Hmm.

  Why microsoft couldn't use Server intuitive/descriptive names more is a mystery. In any case, I have whitelisted *. symcd.com and of the limited testing it seems to be resolved.

• WRT54GS static dns issue

  Hi friends.

  I'm trying to configure a local DNS server to manage domain names local only to the small office for our servers. I have the DNS works correctly (set the local machines and using the dns of your ISP if this is impossible). so I put the ip of the DNS server in the field 'Static DNS 1' of the configuration of the router. 2 other static dns fields are empty.

  the problem is that the router always uses the ISP as the primary dns server and my local dns server as secondary. I check this in two places. first of all, if I go to the 'status' tab, DNS 1 shows the ISP server while DNS 2 shows my local DNS server. Then, if I connect to the device wirelessly with a linux machine, the /etc/resolv.conf file contains the IP addresses of name servers in the wrong order.

  can someone tell me why the router is disobey my settings?

  Thank you very much.

  You have a static IP address provided by your ISP or just static DNS addresses, your router's Internet Connection Type must be set to the static IP address and you should have by default the IP address, subnet mask, gateway and addresses entered DNS... If you entered just the DNS addresses it won't work...
