Cisco :: 5508 Will Not Discover AP's On Other Subnets

Nov 8, 2011

I have a 5508 controller that has 14 APs connected to it. I installed them without an issue. The 2 new APs are on a different subnet. I can ping them from the 5508 controller ping command, but they do not self discover from the web interface. The 2 new APs are at a differnet physical location.

Cisco Wireless :: 5508 / How To Map Two Different Subnets To One SSID

Dec 12, 2012

we have two offices in same city at different location however we are planning to bring both the office at same location.Now lets say site A has controller 5508 configured with 24 AP's with 10.10.10.x subnet for internal SSID and Site B which is shifting to Site A campus has different subnet ( 10.10.20.x )  for same SSID.Site B has no controller since they had connection with H-reap and they were using different subnet for internal SSID ( 10.10.20.x ) .....Now i need to add their AP's in Site A controller which will be extended wireless LAN however we would like to keep same subnet ( 10.10.20.x )  what Site B has for wireless clients which is really confusing me ....I have already client subnet for site A with 10.10.10.x /24 subnet  and nearly 200 users are already using this wireless client subnet.... How do i add their ( Site B ) subnet / 10.10.20.x  with same SSID configured  which is globally only one SSID  ?
limitations :I can not create new SSID for site B since same will be broadcasting even in Site A AP's ?Is this possible to map one more subnet of site B to existing SSID with already different subnet ( 10.10.10.x ) ?

Cisco WAN :: 1921 Cannot Get CCP To Discover

Oct 27, 2011

We are a small business that just bought a Cisco 1921 ISR. I am trying to set it up right now but I cannot get CCP to discover it. I am new to Cisco products and IOS.The router is currently set up in a test environment with a USB connection to a Win7 PC for console management. I also have the PC connected to gigabit ethernet port 0/1. I am using putty to access the console which I did with no problem for the initial configuration. After that I thought I would be okay to discover the router with CCP using the IP address I specified but then it prompted me for a username/password which I didn't see in the initial configuration. After this I did some research and found out I needed to set up a few more things so I ran the following commands: [code]

After this the video I was watching said to go in to CCP and specify the IP address or hostname of the router and use the login info that was just created admin/pw. When I ran the discovery I got the failure message: Connection to the device could not be established. Either the device is not eachable or the HTTP service is not enabled.When I run 'show ip interface' I notice 'Router Discovery disabled" is this why it is not working? How can I enable this or what else am I missing here? Am I not connecting to the router correctly? Oh and just for reference our plan is to have this router set up as a VPN gateway and firewall with 2 WANs for redundancy and connecting to our switch via an HWIC SFP for fiber.

Cisco Wireless :: 3502 LAP Can't Discover WLC Using DNS

Feb 8, 2013

i have 2504 controller with software and some 3502 APs. I also using 5 APs now and few days ago I bought some additional 3502 APs and I can't get them connected to the controller. My company admins decided to using DNS controller discovery instead of using DHCP option 43. I'm connecting APs to access ports of Linksys switches and APs not in the same subnet as ap-manager interface of controller. AP succesfully get IP and DNS from DHCP and could ping cisco-capwap-controller. However, I have such messages.

Turn Off Discover - Ability But Allow Ethernet?

Oct 10, 2011

I have Windows 7 64 Bit Pro PC connected directly to the router via Ethernet.This is I will call Ethernet Connection 1.I also have a Windows XP Pro SP3 computer connected to the same router but via a wireless connection.I have both PC's connected together via an Ethernet cable. This I will call Ethernet Connection 2.It all works fine, but I only want my PC's to communicate via Ethernet connection 2.Currently, if I disconnect the Ethernet cable between the computers I can still access the files on the Windows 7 computer via the wireless connection on the Windows XP computer.I've tried to see if this is discoverable by other people using the router by installing Ubuntu on the Windows XP machine and looking at the available networks. Lo and behold, my Windows 7 machine is discoverable and accessible - albeit by a password. This is with the Ethernet cable between the computers unplugged.I have both networks on the Windows 7 machine set to public and all sharing options switched to off. Both computers have the same workgroup name. Worryingly I can still connect to the Windows 7 machine via Ubuntu wirelessly without even using the same workgroup name!All I want to do is connect the two computers via Ethernet Connection 2. I don't want any sharing information going to the router too and hence other poeple being able to see it. Ethernet Connection 1 on the Windows 7 machine is for the internet only (same as for the wireless connection on the XP machine).

Discover Custom Internal IP Of Router?

Jan 21, 2012

Using a command prompt, how do I discover the internal IP of an unused router, which I set to a custom value and forgot? The router is not currently in use for internet access. I would like to access the control panel of the router without resetting it.I attached my netbook to the router with an RJ45 cable and disabled the netbook's wireless adapter to avoid conflicts with my current network. Using an elevated command prompt, I did an "ipconfig /release", rebooted and ran "ipconfig /all", but the gateway entry is blank. An "arp -a" returns as the only interface. A "netstat -a" returns's,'s, and's, but no router internal IP address.Is there a way discover the attached device without resetting?

Cisco Switches :: SLM2008 - Filters Out DHCP Discover

Sep 16, 2012

I'm new on this site and having SLM2008 switches. I've been trying to solve the problem for quite a while, but so far I was unable to solve it. So here it is:
I'm trying to send IP TV from ADSL box (aka Free box) located in a small annexe of the house where the telephone line enters. Whole house is wired with 1Gb CAT6 cable. I'm using this wiring to get internet connectivity in different parts of the house and this works great. Now the idea was to create a separate VLAN on my 3 SLM2008 switches to get IP TV stream from ADSL box to the media box (also provided by ISP, aka Freebox HD). Different V LAN configs did not work for me: Free box HD would stuck on boot claiming it doesn't "see" the network. So then I've decided to go from simple things to more complex and removed the V LAN (came back to default config) and connected ADSL box with Free box HD with just one SLM2008 in between. Surprisingly it did not work! Same error on Free box HD! So I plugged the hub and started my Wire Shark to see what is going on.
First tried without the switch (just with a hub in the middle) and I saw successful connection:
1) Freebox HD send DHCP Discover
2) ADSL box responds with DHCP Offer
3) HD sends DHCP Request
4) ADSL issues a DHCP lease
Free box HD is ready to show any channel from ISP.
Secondly I plugged SLM2008 back and looked at traffic right after ADSL box: No DHCP packets seen at all! Then I moved hub next to Free Box HD and I saw it keep sending DHCP Discover every 30 seconds or so.... And it was not getting reply back.
So my conclusion is that SLM2008 for yet unknown reason would not let DHCP discover pass.... I've tried un managed Net Gear switch and *boom* Free box HD booted without a problem. I looked through SLM2008 settings and I have not found something relevant.
How to make my switch pass DHCP discover? If yes my next question would be how to configure V LAN on 3 switches to make it deliver IP TV to my TV set.

Cisco Switching/Routing :: DCHP Discover Packet Rate Limiting 6509s

Sep 11, 2012

We have a number of 6509s which generally have dhcp relay agents configured on the SVIs.  The dhcp servers are centralised.  Recently we've had one or two faults with misconfigured or faulty devices (blade server chassis and also printers) generating high volumes of dhcp discover packets and causing high cpu on the relevant 6500.  I would like to rate limit these discover packets, which are layer 2 broadcasts.  Storm control can't discriminate between different types of broadcasts and on a gig link would need to be set down at about 1% to have much effect on the problem.  I've looked at CoPP and also mls hardware rate-limiting but as I understand it, these two features don't control broadcast traffic. I also looked at dhcp snooping but if an interface receives a high level of dhcp discover broadcasts, e.g. over 100pps, I don't want it to go error-disabled (as this would knock down the whole edge switch),  just to drop the excess packets.

Network Scan To Discover Rouge Apple Device Host Names

Sep 27, 2011

Anyway, I am looking for a way to discover host names of Apple devices (namely iPods and iPhones) that are on our network. I've tried a number of programs like Nmap, Advanced IP Scanner, and LanSpy to name a few. All of them will report back the MAC address with no problem but no dice on resolving the host name.

My goal is to use the host name to identify the device, and ultimately the person with the device. Any thoughts on how I can go about this? Is there a setting in Nmap I'm missing or perhaps a better program to use?

Linksys Access Point :: E4200 Discover New IP Address Of Reconfigured Router

I have changed from a DSL internet service to a Comcast cable system.   I have setup my E4200v1 router as an Access Point, to extend coverage in my building.  It works fine, but I can no longer log on to  the unit using its'  IP address  The browser returns the message "Internet Explorer cannot display the webpage."   If I want to tweak the settings the only thing I can think to do is to push the reset plug, back to factory settings and go through the whole process.   Is there a way to discover the new IP address of the reconfigured router?  I left the default address as it was when I made the changes to AP status.

Linksys Wireless Router :: X3000 Some Wifi Clients Can't Discover Connection

Nov 23, 2012

I've just upgraded my home wireless from an NetComm NB5540 + modem to a LinkSys X3000.Internet access works fine for all devices, but some wireless devices can't "see" my Win7 desktop system that's on a wired connections to the router. Galaxy Note phone (running ICS 4.0.4) can discover and connect to file shares on my desktop system without any problems.Asus Transformer Prime tablet (running JellyBean 4.1.1) can see the router on the local network, but can't see my desktop. Even if I manually type in the IP address it can't connect to itLikewise my old WinXP laptop can see the router but can't see or connect to any other devices.
I tried connecting the NetComm router with just Wifi configured to one of the ethernet ports on the X3000, so I've got two Wifi networks running in parallel. If I connect to this second WiFi network with any of the above devices then they can all discover and connect to my desktop system on the wired connection to  the X3000.

Connection Between Two Subnets

I have a home network. There are a total of 3 PCs. Each runs Server 2008 32 bit. One PC - Lets say Server A has 2 NICs with Ip addresses,, Other two computers Server B and Server C have single NIC with addresses and resp. So as you can see that there are two subnets - 1 and - 10. I can ping B and C from A. I want that B and C can also ping each other and if I run tracert on B or C, it should give me the route to the destination via A. All this without any other hardware. Like using route add... etc eg. if I write tracert on B, it should return a route like

How To Connect Two Subnets

Mar 26, 2013

I have 2 DSL Lines going into a load balancing router. The load balancer is set up to distribute the traffic equally on the two lines, hence doubling the bandwidth. Though great at load balancing, it cannot handle DHCP for the 50+ users on our network, and therefore we are using another router for DHCP, which is running DD-WRT firmware.DSL 1 - 2 - Balancer - external, internal DHCP Router - external, internal other devices - 192.168.1.xThe load balancer has many options to direct traffic to one WAN port or the other based on IP address, which we would like to implement. But right now, since all my devices are on the 192.168.1.x subnet, it can't see anything but the DHCP router. So essentially it thinks it has only one client.

Cisco :: Designing A Network Using Subnets?

Now with project itself, I'm designing a network for a large organisation with a different number of hosts at each location.These are, 500,18,52,236 and 12. The location with 500 hosts is the head office, to which every other branch has a wide area network connection through a serial link.How many subnets would I require? I wrote down subnet details, but only for 5 subnets, a subnet for each location. Is that all I need? Or do the WAN connections count as subnets

Cisco :: Communication Between Subnets On 5510

Sep 13, 2011

I am working on a Cisco 5510 with multiple interfaces and requirements. I have experience with Cisco IOS, but not too much with the ASAs. I seem to be getting a bit confused on the NATing and ACLs on a firewall that was started by another employee, who is no longer here. With my current config I can get the firewall in place (we are currently using an older PIX) and most basic functions work except for two key things: 1) communication from the finance interface to the inside interface. The finance subnet has some restrictions that you will see in the ACL- we are trying to limit connections to the those systems, but they need to be able access an e-mail server on the inside. 2) communication from the DMZ interface to the inside interface. Maybe related to the first problem?

I've been trying to search and not been able to find a good answer (some say I shouldn't have to do anything, everything else references NATing, which I currently don't do and would rather not do).The servers I assign these to, I'd like them to have the public ip assigned directly to them.
