I have a WLC 2106 which is configured and working as follows: [code] how do i get the AP at Site B to use the local server (10.0.28.x) to hand out DHCP leases?

My network topology is as follows:
Internet <-> Residential Gateway (RG) from ISP (OEM: Pace) [192.168.1.254/255.255.255.0] <-> RV180 [192.168.1.253/255.255.255.0] <-> SG500 switch [192.168.1.250/255.255.255.0] <-> rest of network.
I know this is a cascading LAN-to-LAN arrangement. The cable from the RG to the RV180 is from a LAN port on the RG to a LAN (not WAN) port on the RV180.
I eventually want to segment my network into a few VLANs from the RV180 down. I am aware most people would recommend DHCP on the "primary" router, but the RG is non-VLAN aware, so I figure I need to handle the DHCP off the RV180. At the same time, I have also opted not to do a LAN-to-WAN cascade because I want to retain the ability to configure the RG from the rest of the network and not have to cart a computer over to the RG to do it.
On the RG, I've disabled DHCP, and placed 192.168.1.253 in the DMZ.
On the RV180, I've enabled DHCP and put it in Router mode.
The issue is that I do not have any Internet connectivity. If I allow the computers in the network to receive IP addresses over DHCP, the default gateway that is communicated is 192.168.1.253, which is the RV180. If I configure static IPv4 information on my computers to point to 192.168.1.254, I am able to connect outside, as you would expect.
How can I get the RV180 to pass out DHCP IP addresses, but point to 192.168.1.254 as the default gateway? I thought the solution might be to create a default route (or something). I went to the static routes tab but it wouldn't let me enter 0.0.0.0 as a destination IP to route through 192.168.1.254.
Further down the line, is it possible for both the RG and the RV180 to connect directly to the SG500, along with the other nodes in my network? That way the RV180 only serves to maintain the VLANs and pass out IP addresses via DHCP, instead of having it be the choke through which everything goes through on the way out?
I've been having a weird issue lately with my WRT310Nv2. Sometimes when we, and by we, I mean two different computers (one Mac, one XP PC), try to go to a website, it will point us to an entire diffrently website. For example, earlier today I attempted to go to Twitter and twitter.com appeared as some random Blogger website. I've had issues where Amazon.com kepting point to UPS.com, or Facebook.com pointing to MySpace.com, etc.
I haven't been able to pinpoint a regular pattern, except the fact that it is most likely the wireless network, since the Windows PC (Server 2003) plugged directly into the router has never had this issue.
I've just bought an AIR-WLC2106-K9 and 3 x AIR-LAP1142N-E-K9 and I'm having a problem getting the AP's configured.
Firstly, the controller did not discover the device when it was on the same sub net, I had to plug it straight in which is no good for wireless-n due to the 100Mbps port speed on the controller. Secondly, when I am editing the AP through the controller webpage, none of the details are saved after applying changes (static IP etc).
I followed the Cisco quick start guide for the controller to get the basic config, radius server details etc in. It is running software version: 4.2.61.0
I am trying to get a controller to work on my network. output from the switch arp table.

The switch see's it but i can not ping or access it via web or telnet.
we have the WLC and 2 x Aironet AP's that is powers over PoE. The other day is was reloaded and since then the AP points are Blinking Red, according the the Aironet manaul this means some sort of boot error? They are also not appearing on the WLC from the GUI or CLI running a show ap summary. Interesting though I can see them via CDP, however they are not picking up IP's as they are listed as 0.0.0.0. After checking with colleagues I was told these were set statically.
Is it possible that the points not having IP addresses is a sign of a corrupt boot environent? I would have though they would not have appeared in CDP if they were corrupt?
I did not set this up in the first place so a little puzzled at the moment? Nothing has changed on the config bar using a different NTP server on the network?
I am about to configure a brand new AIR-WLC2106-K9 V05 and didn't manage to find what is the deafult IP address configured on the device. I need it so I could start Web GUI management session.
View 4 Replies View RelatedI have a WLC2106 and AP3502i. The issue that I am having is the radio for 5GHz is not showing up in "Wireless > 802.11a/n" (see attached screenshot) I am not exactly sure what was the problem. When I went to 802.11b/g/n I do see an entry for 2.4Ghz radio, but nothing on 5GHz.
I have the AP plugged directly to my 3550POE, and when I used the command "show power inline" it says that the switch is providing 15.4W and there is still 345W remaining on the switch. The LED on the AP is solid green. I issued a no shutdown on dot11radio1 and the status is up/up, but there is still no entry under "Wireless > 802.11a/n"
I'm running 3 WLC 5508, 2 of them running image AIR-CT5500-K9-7-0-116-0.aes, one AIR-CT5500-LDPE-K9-7-0-116-0.aes.
On the 5508 running the LDPE-image, I have 9 WLANs (170,171,180,181,190,191,281,282,283), all defined with admin status "ENABLED".
WLANs 180,181,281 belong to a defined AP-group, WLAN 190,191,282 belong to a different AP-group.
WLANs 180,181,190,191 are defined as H-REAP. The H-REAP APs registers without any problems at the backup WLC and switches back successfully to the primary controller after recovering from reboot. Unfortunately the WLANs 180,181,190,191 show status "DISABLED" every time the primary controller comes back and I have to enable them manually.
Doing exactly the same procedure with one of the other WLC, running AIR-CT5500-K9-7-0-116-0, I never face this problem.
I didn't design the job, but is pretty straight forward, except the following, the design has a single wlc 5508 with 2 physical connection between two non cisco switches. There are 2 initial WLANs to be created. I am ok with most of the wlc config execpt the following:
Now from my understanding of everything I have read recently, you can't use LAG on the 2 physical connections if they connect to 2 seperate switches, unless, although not offically supported, the 2 connections are on either 2 3750s in the same stack or a pair of 6500s running VSS. So I believe that in my case 2 seperate connections from the wlc to 2 non cisco switches will not work with LAG. Is my understanding of this correct?
Is there a way to maintain the 2 physical connections from the wlc to the 2 non cisco switches to maintain redundancy?The wlc will have a management interface obviously, but from what I have read, the 2 WLANs that are going to be created have to have their own interface on the WLC. Which I understand as the managment int and each of the 2 WLANs are on different subnets.
If I don't use a single uplink to one of the non cisco switches (either 1 or 2 physical connections) using LAG, it appears to me that each of the interfaces ( management, wlan1 and wlan2) need to have a physical connection from the WLC to the switch, with each interface mapped to a physical port on the WLC, so correct me please if I am wrong, but this would mean I need 3 physical connections between the wlc and the swtich?

These are only occuring for clients that are disconnecting....
They can reconnect after a WLC reboot....
We have swapped APs.....
I have seen this error in other forums but it says not to worry about it. There has to be a connection between this and clients getting disconnected. We have anywhere between 10-50 clients on the system at any one time.Is this a client issue (nic firmware, version) or is this an error in the controller??

I was successfully running 2 SSID's at a remote site, one SSID was configured for H-REAP local switching, dropping out to the local site VLAN X, and the other SSID was a central switching guest WLAN anchored to a WLC in a DMZ.I configured a third SSID at the local site running H-REAP local switching, and now I cannot see the guest SSID anymore, it does not appear to be broadcasting.Is there a maximum of 2 WLANs/SSIDs when operating in H-REAP mode?
I am in the process of building a small educational lab. I just want to make sure that I am not going to have any AP registration/join issues due to regulatory compatibility with a AIR-WLC2106-K9 controller and a AIR-LAT1142N-N-K9 access point. Will this work and if so, will I then be in the clear as far as having devices like my computer and phone attach to the SSID?

View 6 Replies View RelatedI have a 2511 TS linked into my CCNP lab and configured it with default gateway pointing to my ADSL router. The TS has a staic local IP in my LAN also I have port forwarding set up on my ADSL router to direct all Telnet (not cofigured for ssh yet) sessions to the TS.
The TS is linked to the ADSL router via the transceiver module ( CentreCom AT-210TS) which feeds the ADSL router with ethernet connection.I have tried to access the TS from a remote location but with no joy, fortunately I also have it consoled to my PC so I SSH to the PC and then run my terminal emulator from there. Using SSH to the PC and then minicom to the TS when doe this way (Remote Location>Ubuntu>minicom>TS) I can see the ethernet interface has no MAC address when i do a sh internet eth 0 mac is set to 0000.0000.0000.
I don't want to be connecting via ssh to PC before accessing the TS but instead just want to connect to the TS; for the life of me I still can't explain what's going on.
2 dhcp server on the same lan segment not thesame ip add series , how can i prevent to lease ip from another ip series
View 2 Replies View RelatedI have a LAN running on a 10.60.1.* scope and I am running out of IP addresses. My windows server 2003 IP is 10.60.1.3 router is 10.60.1.4, If I create a superscope with 10.60.1.* and 10.60.2.* scopes within it and add an IP address from the 10.60.2.* range to both the servers and routers network configurations would this allow the clients on both scopes to see the network? The router links our office to other offices as well would the new IP range cause all kinds of routing issues?I know with the resubnetting option changing to a 255.255.254.0 from the current 255.255.255.0 would allow the use of 10.60.0.1-10.60.1.254 in a single subnet but I suspect this would cause problems with seeing the other offices unless all routers were reconfigured to recognise our offices new subnet mask.
View 1 Replies View RelatedI am trying to set up a small domain for my business. I just purchased a Windows 2008 server and would like to use it as my domain controller.Also, I just had a new ATT DSL line put in. It came with a 2Wire modem/4-port router/wireless router device, therefore the modem can handle DHCP. The line has a static IP address as well so that I can eventually use my own exchange server and web server.I have tried 2 different configurations and couldn't get either to work) I tried to put the router into Bridged Mode and use DHCP server on my server using a PPPoe connection to connect to the Internet. I was confused as to what my static IP address and default gateway of my server should be.2) Then I tried to turn DHCP server off on the server and routing back on the modem/router. This didn't work either.What method would you recommend and why? Also I have some additional questions on each method.
Method 1)
* What is the static IP address of the server. Is it in the 192.168.1.x address or the static IP assigned to my account?
* Do I need a second Nic Card And Router to connect to the rest of my network or can I use the router provide
* What would the Static IP addresses of the additional PC be. Do I need more than 1 static IP from AT&T Method 2)
* Will this allow me to use all internal IP addresses on my machines and use port forwarding if I want a specific box to be a web server or exchange server.

View 1 Replies View RelatedI have two 6509s both with single FWSMs running in transparent mode with bridged Inside and Outside VLANs.I have my Core A set to STP priority of 8192 and Core B set to 16,384 to make Core A the root for all VLANs.Problem I have is when I look at spanning-tree on Core A for Inside VLAN 324 it states to get to the Root go via PO100 (Cost of 9) and that the Root also has a Priority of 8192, but as the designated Root has a lower MAC address it's pointing to the etherchannel. PO100 is L2 Etherchannel between the Cores.Moving accross PO100 to Core B and running the show spanning-tree command I can see that to get to the Root Bridge I need to go via PO272. PO272 is the internal Etherchannel to get to the FWSM on the Core B Switch. This shows a cost of 6 to get to the Root and a mac address of the Root Bridge which resides on Core A (Outside VLAN 124)To give some perspectibe,theoutside VLAN of the pair has it's STP ROOT on the Core A switch as intended?

View 1 Replies View RelatedI've done a very crude drawing of the network setup I'm working on. I just need to run an idea past some network guru's to see if I'm right about my idea.
The existing network consists of
Internet
Proxy Server
Several switches scattered around school
PC's
What the school wants to do is setup a side-along wireless network that uses the same physical switches but on a different subnet. The current subnet is 10.172.1.x .
To facilitate this I'm running a 2008r2 running RIP V2 to route internet traffic to 192.168.1.x subnet. I've had the wireless units use a static address and their own dhcp servers on the 192.168.1.x subnet. Wireless devices found their way to the internet fine. But I'd like to control the addresses from a single point of contact, hence the 2nd domain server running 2008r2. There are reasons for using a 2nd server, I've covered this in previous topics. If it's important, lets call it an intellectual exercise and leave it at that.
The question(s) : If I run a DHCP server on the 2nd server serving 192.168.1.x addresses, then any device on the physical network will obtain either an 192. or a 10. address correct ? The wireless devices will only take a 192. address because the wan address is statically assigned to a 192. address ?
The 2nd question : By setting a static routes out of the 2nd nic on the 2nd server, I can control the dhcp server so it will ONLY route dhcp requests to the statically assigned wireless devices ?
I have Server 2008 R2 DC & One ISA server 2006 enterprise. im facing problem with DHCP unable to give DHCP IP from internal LAN. Its taking IP from External LAN IP i.e. connected to Linksys external Router which has DHCP enabled with different IP class i.e .class B. After shutdown client PC it will take 0.0.0.0 no IP will be assigned & says linited connectivity.
View 4 Replies View RelatedI have two locations both about 800meters apart, one is my home and the other address is a campsite where i have a linked router network (WDS with routers running ddwrt) where campers can all use the internet and also i have several IP cameras. Obviously both address have different gateways and therefore their own DHCP server. Everything was running perfectly until.I linked both of my address up using a long range antenna and now i am having problems.
Sometimes the two DHCP servers are competing with each other (i need both addresses on the same subnet in order to view my IP cams from home) and sometimes the computers log on to the wrong gateway. Its very annoying because the only way i can resolve it is by turning of the "linking routers" for a minute and then the Computers log onto the correct gateway. This happens to clients both side of the bridge. I have many different clients on both side of the bridge so assigning each computer (via windows) its fixed default gateway and DNS is out of the question as some of the clients are Camper's PC's and mine and my wifes laptops swap between both locations.
Now my query is, how can i block both DCHP servers from going over the bridge? OR can i have them on both separate subnets and still view my IP camera and still access all the routers from each subnet (i need this because sometimes i need to reboot the routers from home)

The purpose is that users in vlan 1 should get an IP address from DHCP server1, and users in vlan 2 should get an IP address from DHCP server2. Both DHCP servers are configured in a stack of C3750 switches, which acts a a L2 switch.
