Cisco Wireless :: DHCP Error With WLC 2504 And Aironet 2600 Setup Across Subnets
Apr 2, 2013I have just setup a new WLC 2504 controller to manage a WiFi service that will span 6 geographic locations. The local networks at each location are on different subnets (all 192.168.x.x) and are linked up via IPSEC VPN links, and there is Active Directory spanning the sites, with DNS and DHCP servers running at each location.
I tested the WLC at our main office with a single AP, and it worked fine. The AP set itself up, and wireless devices connect with no probs. Great! Yesterday I headed out to one of our remote sites, and connected an AP to their network - and that seemed to work fine too. Within a few minutes I was able to see the WiFi network I'd setup, and my smartphone connected to it straight away (as I'd rpeviously connected at the main office), so I was pretty happy that all was working well.
This morning however I've had notification that wifi performance at the remote site isn't great. I've got someone to check their ip address, and I've found that their IP address and default gateway match the LAN at the main office where the WLC is based - NOT the LAN where the wireless client is. Obvioulsy this is not ideal!
(I guess I HAVE done something wrong!?). And how can I get wireless clients at remote sites to pick up an IP from the DHCP server at THEIR site?
Cisco Wireless :: 2504 Management On VLAN?
May 10, 2012We are installing a 2504 with management on VLAN2. The management port is on interface 1 which is attached to a layer 3 3750. From other VLANs in the network we cannot manage the 2504 controller with the web manager. We are running the latest code, 7.2.103.0, since we are using 3600 APs. We have a TAC case open, but spent 3 hrs with them and they can't figure out the problem. TAC did some debugging and saw that the 2504 is ARPing for the address of the PC on the other VLAN instead of sending the packet to its default gateway. How to get success with the management interface on a VLAN and managing the controller from another VLAN?

Sep 25, 2012is it possible to Manage the 2504 Controller over a separate Interface. Exmaple: Port 1 is used as controller management interface (untagged) - AP's are connected to the same VLAN Port 1 is used for Guest Traffic (VLAN 3 tagged) Port 2 should be used to manage the WLAN Controller from the internal LAN. (tested with untagged, tagged, same issue)
with this Setup it is possible to ping the Port 2 IP-Address from the internal LAN but if you try to connect to the controller, the Browser shows "Site not reachable".
I also enabled "Management via Wireless" but without success. I also tried to add the "management" VLAN as tagged on the management Interface with the same effect, the controller is not manageable from the internal LAN. On 5508 WLAN Controller i have an similar setup, but with LAG Port enabled. There this works.
The only interface were i can manage the WLAN controller is from the management Interface.
Cisco Wireless :: 2504 / Assign SSID To Interface That Has Dynamic AP Management Enabled?
Jan 3, 2012I am tasked with configuring a 2504 wireless controller. Is it possible to assign an SSID to an interface that has dynamic ap management enabled?
Scenario:
Location1:
1) 10.0.0.0/24
2)192.168.0.0/24 DMZ
Location 2:
1) 10.0.5.0
Both locations are routable using network 1 at each location. However, I need to configure several access points and send them to location 2. These access points will communicate with the controller at location 1 on network 1. Two SSIDs will need to be on network 1 at location 1. The other SSID will be on Network 2 at location 1. This network is not routable.

Apr 12, 2012I 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, 10.0.0.10/30, 10.0.0.2/30. Other two computers Server B and Server C have single NIC with addresses 10.0.0.1/30 and 10.0.0.9/30 resp. So as you can see that there are two subnets 10.0.0.2 - 1 and 10.0.0.9 - 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 10.0.0.9 on B, it should return a route like 10.0.0.1-----10.0.0.10------10.0.0.9.

Mar 26, 2013I 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 - 10.1.0.1DSL 2 - 10.2.0.1Load Balancer - external 10.1.0.2, 10.2.0.2 internal 192.168.10.1. DHCP Router - external 192.168.10.2, internal 192.168.1.1All 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.

Sep 13, 2011I 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?

Mar 11, 2012I purchased an ASA 5505 and placed it between my Cable Modem and Cisco 3745 router. The outside interface on the ASA is dhcp, the inside interface is 192.168.100.1. The outside interface of the 3745 is 192.168.100.2 and the inside is 192.168.1.1. The VPN pool is 192.168.200.10 - 192.168.200.10.
1. When I establish a VPN session to the ASA, I can ping and access any resources dierectly connected to the ASA's interfaces and on the ASA's internal 192.168.100.0 network. However, I cannot access any resources behind the 3745. I cannot even ping 192.168.1.1. Even directly connected hosts on the ASA cannot access Hosts in the 192.168.1.x subnet. There appears to be no traffic between 192.168.100.0 and 192.168.1.0.

View 21 Replies View RelatedCisco VPN :: ASA 5520 Not Processing RRI Subnets
Jun 18, 2012I am coming to this forum because TAC and several CCIEs are having trouble finding me a solution to my problem.
I have Two 5520s each running 841 connected in two different data centers with two different internet providers. I have 100+ 5505s that have the capability to connect to either 5520 via EZVPN to either 5520. Up to now there has not been a need for a 5505 connected to one 5520 to talk to another 5505 on the other 5520. Each 5505 accesses network resources as in any enterprise network. Our company recently started telecommuting and I have been giving 5505s and a VOIP phone out to people. What was discovered is, if you are on one 5505 connected to a 5520 and the other 5505 is connected to the other 5520 the audio in voip does not work. If both the 5505s are connected to the same 5520 than everything works fine. Conversely a 5505 on one 5520 cannot ping a 5505 on the other 5520. 5505s on the same 5520 can ping each other no problem.
My problem: All 5505's are configured for a 172.18.xxx.xxx 255.255.255.224 subnet. This subnet is not used anywhere else. So I have a 100 Class "C" subnets carved up into 255.255.255.224 networks. If I look at a specific route for a subnet on one 5520 I see it pointed to the outside interface via RRI. I can look for the route in the 5520s connected CORE switch and I see the route pointed to the 5520. We have a fiber connection to the CORE in the other data center. The route is in this CORE switch as well. When I look for the route in the 5520 connected to this core it is not there. I have all other routes visible but not this particular route which should show on the inside interface. All I show on the 5520 are the 5505s connected to this ASA. So the 5520 is not processing the RRI subnets from the other 5520 and vise versa. Thats why a 5505 on one 5520 cannot ping a 5505 on the other 5520. I only see 172.18.0.0/27 on the outside interface of both 5520s. I do not see any 172.18.0.0/27 on the inside interface on either.
I have had numerous TAC cases open on this and no one seems to either understand my problem or have a solution for me. My local sales rep CCIE says the problem looks like a bug in 841 (which I am running) and that the ASA is not processing RRI from eigrp which I am running as well. The whole network is running the same instance of EIGRP including the 5520's.
My questions:
1) Is it possible the 5520 is not allowing 172.18.0.0/27 on both the outside and inside interface? Even though all subnets are masked proper the ASA maybe thinks it is being spoofed? I have not been able to confirm this using the real time log.
2) Could this really be a bug? I have looked at all the release notes and have not found anything resembling my problem. TAC has not recommended that I upgrade or downgrade my IOS.

How To Find Out Range Of Subnets For Given IP
Jul 7, 2011if some gave me an IP address and subnet mask, and they told me to identify the range of valid subnets I have no clue how to do it. I know how to work out the total number of subnets and hosts, you just look at how many subnet bits have been borrowed and use the 2^ formula. For example with the IP 172.28.123.0/25 I know the default mask for a classs B address is 255.255.0.0/16 so in this example we have borrowed 9 subnet bits to give mask of 255.255.255.128/25 and 7 host bits remain. In order to find the total number of subnets you do, 2 to the power of 9 because we borrowed 9 bits, which tells us that there's 512 subnets and to find out how many hosts we do, 2 to the power of 7 because we have 7 host bits, so that gives us 128 hosts in each subnet. Now this is where I get lost, how do I find out the number of the first and last subnet? I know there's 512 subnets and each subnet has 128 hosts. But I don't know the number of each subnet, the range to be more precise. How do I workout the first, second, third, fourth etc subnet address

Jul 2, 2012I have :
- two different subnets (S1, S2)
- these subnets are connected to an IP backbone via wirelles acces points
I would like to physically connect these subnets together so the networks devices in S1 could directly communicate with the devices in S2 and vice versa without going through the backbone.
The obvious solution seems to interconnect these subnets with a router or a switch L3. But I would like to connect these subnets and stay at layer 2.
So, is it possible to connect S1 and S2 with a switch L2 ? If I do that, what is going to happen? Can I create just one subnet S3 from this two subnets when I connect them together and have my two separate subnets back as soon as I disconnect them?
Folder Sharing Between 2 Subnets?
May 11, 2012our office has 2 branches recently the static ip of the branch was changed to a different subnet. earlier it used to be
111.170.150.140 subnet mask (255.255.255.128) main branch router (1) ip which forwards all request to server (dmz) - unchanged
111.170.150.141 subnet mask 255.255.255.128 sub branch (2) router ip changed to 111.170.150.61 subnet mask 255.255.255.224
after this change i am not able to access shared folders on the dmz server (1) (111.170.150.140). i am able to ping the ip and also able to open remote desktop connections from sub branch (2).i suspect that it is because of subnet change as i was earlier able to access shared folders?How can we access the shared folders across the subnet? what settings to change?
Making 4 Subnets For VLANs?
Dec 4, 2012You have to make 4 subnets for 4 VLANs, the router interface assigned to each VLAN is the LAST usable host on the subnet.so unless I'm really bad at networking the graph should be:
NET ID // HOSTS // BROADCAST ADDRESS // VLAN
192.168.0.0 // 192.168.0.1 - 192.168.0.62 // 192.168.0.63 // VLAN1
192.168.0.64 // 192.168.0.65 - 192.168.0.126 // 192.168.0.127 // VLAN2
192.168.0.128 // 192.168.0.129 - 192.168.0.190 // 192.168.0.191 // VLAN3
192.168.0.192 // 192.168.0.193 - 192.168.0.254 // 192.168.0.255 // VLAN4
So if I'd have to write down a single host configuration for VLAN2..I think it should be:
IP: 192.168.0.65
subnet mask: 255.255.255.192
default gateway: 192.168.0.126
Is this correct? I'm not sure whether the default gateway should be 192.168.0.255 (as would with normal subnets) or as I wrote down 192.168.0.126, this is the first time i've ever gotten assignments including VLANs and I havn't really gotten a solid explanation.

Cisco :: SG200-08 Setting Up Multiple Subnets
Aug 26, 2011I am setting up my home lab to practice and play around.I have VMWARE ESXi environment with two workstations as my servers.I would like to setup two domains with two domain controllers but i want each domain to have its own subnet.So this is my setup. I have Cable modem from cablevision , thay connects to my router which is Apple Airport which acts as the DHCP server. DNS server and default gateway. The network on the router is 10.0.1.xThen i have two switches . One is a 5 port unmanaged switch that connects to the three physical desktops .Then i have a Cisco small business switch SG200-08 that connects to my ESX servers and NAS. Now currently all is good and working but like i said all my machines physical or virtual get an IP that is 10.0.1.x and they get all this from the router. And i think i can setup two domains with two domain controllers without an issue and they will all get an IP address of 10.0.1.x. This is all good but i want to have one domain on one subnet and other on another so for example one domain will have 10.0.1.x and other 10.0.2.x. I am just not sure what i need to to get this setup like this. I know my SG200-08 supports vlans and i am pretty sure on the apple router you can only have one subnet i think. So can i do this with my current setup by setting up a DHCP server with two scopes ?

Cisco WAN :: 3750X / Isolating Traffic On Different Subnets?
Apr 19, 2012What I have is two Cisco 3750X switches, 10 bridges, and 10 routers. What I'm doing is throughput testing. The problem is all of the routers have identical subnets because in the real world there won't be two of them in the same place. The 10 bridges were the easy part. I have one switch dedicated to LAN side and one dedicated to WAN side. Since the bridges themselves allow any traffic through because they are bridges I set all of the individual ports to essentially be their own subnet by making them L3 ports. Then, I set the switch to route the traffic based on subnet through the correct port using the ip route command in the CLI. I'm using a Spirent to generate traffic and the spirent lets me wrap traffic on different streams in different IP addresses. I made the uplink have a subnet of 10.0.28.0 and I made every port have a subnet starting with 10.0.5.0 being incremented by 1. This allowed me to send traffic from source address 10.0.5.5 to destination address 10.0.28.5 and vice versa by telling the switch to route any traffic with a 10.0.5.0 subnet to port 1 (first device) and any traffic with a 10.0.28.0 address to port 24 (uplink). The reason this works is because bridges don't care what the traffic is or where it is going so everybody is fine and happy. Now I have to introduce 10 new devices that are all routers while maintaining the previous set up and I'm stumped. I've tried everything I can think of, different Vlans, trunking, routing, L3 ports, etc. If i try to isolate everything by Vlan they can't talk to each other. If i try to isolate everything by Vlan and trunk the uplink port it won't work because you need to do Vlan tagging and my device doesn't do that and I don't think the switch can do that for you. The routing doesn't work because the uplink port has to be it's own subnet and when that subnet tries to send traffic to the router it's considered foreign and gets dropped. With L3 ports you run in to the same problem, you can isolate all of the individual ports with their own subnet but the uplink port has to have a different subnet which automatically causes the router to drop the packets. The only configuration that works is a completely default dumb switch configuration and that is unacceptable because I need all of this traffic to be isolated because of the bridges. Without the isolation, all of the data will go through the nearest easy hop which will be one of the bridges, even if that isn't the right path the switch doesn't know any better. I can change the subnet on the routers but I can't deviate too far from the original subnet which is 192.168.0.0. I tried setting up different subnets by incrementing the third octet by 1 every time, 192.168.0.1, 192.168.1.1, 192.168.2.1, etc. and think this setup will work I just don't know how to set the switch up. Setting up the switch to route the traffic properly without changing the subnet on any of the devices would be ideal.
