If we have 2 Cisco 2504 series wlcs and use multicast features in both and both are primary and secondary for LAPs. what about of we use multicast ip address let's say 255.239.1.60 can we use the same ip address for the secondary controller too or we should use any other ip ?
View 7 RepliesI am setting up two 5508 controllers, one in HA mode, and one the primary for the remote sites in question. I plan to have these units service wireless for MPLS conected regional sites (each with their own local subnet). I was planning on using the cabled hosts network in each site for the wifi addressing and was thinking a different addressing for Guest Access, is this common? I'm obviously concerned with guest access clients but don't know enough how their trafiic is segregated from normal wifi traffic.
Also, when I stand up the controllers the management interface and ap-manager won't be in the same network as where the hosts or LWAP's will reside (routing access will exist though).
Q: a client has a network with 60 AP's controlled by a AIR-CT5508-50-K9 (+ L-LIC-CT5508-25A) with a redundant power supply. Can he get full redundancy by purchasing a second controller? If he purchases one, can he bring it into the network? What about the extra license for 25 extra AP's installed on the first controller?
View 4 Replies View RelatedI am configuring two 2504 controllers, which I ordered together, however they run different software versions and I don't have a contract/ login to download wlan controller software from the Cisco website. The one with the newest version runs 7.2.103.0 while the other one runs 7.0.220.0 I want to run them together in the same subnet and use them for redundancy (10 AP's will connect).
Is there a way I can download the software from the controller, just like I am able to do with an ASA firewall? Then I can upload it to the controller with the older software version.
I have 2 x Redundant Guest Anchor Controllers (5508) located in 2 separate Data Centers with all the management and guest user VLAN spanned between two. Everything is working fine with the Guest WiFi access except the DHCP functionality as the Controllers are acting themselves as the internal DHCP Servers.
This is how I tried to distribute :
network. 10.1.0.0/23
gateway: 10.1.1.254
Controller 1, DHCP Server pool: 10.1.0.2 - 10.1.0.254 Gw: 10.1.1.254
Controller 2, DHCP Server pool: 10.1.1.2 - 10.1.1.254 Gw: 10.1.1.254
As the user load balancing between the Anchor Controllers cannot be controlled (i.e. they are active/active), the same client sometime getting 2 different IP addresses from both the Controllers (as they do not talk to each other in terms of DHCP) hence depleting the pool addresses.
I guess one way of solving this is to just run 1 DHCP server in one of the controllers but that defeats the purpose of having N+1 Controllers. Is there a better way of doing the DHCP load balancing and having full redundancy at the same time?
I have a customer who has 2 NCS servers; 1 residing at their corporate site and the other residing at their local site. They have a WLC2504 controller at the local site. They would like to connect both ncs servers to to the local WLC. Is it possible to connect 2 ncs servers to a single controller? Can WLC configuration databases on two different NCSs be the same? How can you prevent 1 NCS from overwritting the other?
View 5 Replies View RelatedIs there any way to configure a wired guest network with a combination of 5508 and 2504 wireless controllers? I am aware that the 2504 does not have wired guest functionality, however is it possible to set up a wired guest on the 5508 and using mobility anchors, transmit the l2 information through eoip to communicate with the remote vlan?Home built NAC solution, using 802.1x authentication on switchports for public areas. If user is an employee, communicates with the supplicant on their machine, and places them on an internal vlan.If user is a guest, user fails 802.1x check and is placed on a "guest" vlan with an ACL and external DNS.If placed on the guest vlan, the user has to accept a terms of use form.This is working currently with our 5508s without any issue, however we have some remote offices we'd like to roll this out to that are using 2504 controllers. I'm hoping there's a way that I can use the 5508 as an anchor or vice versa to make this work.

We have configured multicasting for our Nexus 5K switches. and for the most part everything seems to be working until recently.
Setup is we have 2 Nexus 5k switches connected via Dark FIber from Site A to Site B. Site A is sending the multicast traffc and Site B is receiving it.
I am not a network person, but I am not sure our Network Team is qualified either. For a long time we have been using a dying Cisco 2950 100/MB switch for imaging our computers using GhostCast. Multicasting on the 2950 was never an issue other than it was flooding the switch and making all the other ports unusable. But at least the multicast portion was imaging with decent times. We had two Intel Pro NICs teamed to get 200 MB/s and a typical multicast session was about 6.5 minutes. When using only 1 NIC, it takes about 8.5. Running two concurrent unicast or multicast sessions, well that is a different story. It then triples or quadruples the time.
Now we have a 3560G setup. A single session takes a little over 3 minutes. If we multicast off of this switch, the time is about 12.5 minutes. That is 4 minutes longer than the 2950! If I run 3 concurrent unicast sessions, it takes all of them between 3.5 to 4 minutes. So obviously there is an issue with multicasting.
The switch is in a lab separate from the production network. The server with our ghost images is plugged directly into the switch and so are the computers we are imaging. From what I was told from the Network Team is that IGMP snooping is on, but multicasting is off. He said that multicasting does not need to be turned on since all traffic is going through the local switch. Probably true since our old switch didn't have multicast turned on either, but it still imaged using multicast faster.
Below are some screen shots of the imaging. The first one is the 2950 using multicast to 3 laptops. The second one is the 3560 using multicast to 3 laptops. Finally is the 3560 using 3 unicast sessions to the same 3 laptops.
Here is my basic network layout for multicasting for Syn-apps
Multicast Source-->3750 SW (add PIM SM-DM? Yes/No)-->3845 WAN Router (add PIM SM-DM? Yes/No)-->T1-->2821 (add PIM SM-DM? Yes/No)-->3560 SW (add PIM SM-DM? Yes/No)
OK, in this is it necessary to configure "IP Multicast-routing" on the switches? Do I configure PIM on all interfaces that will handle multicasting (router and switches?) If PIM is enabled on the 3750 do I need PIM configured between the 3845 and the 2821 ? Do I configure the Auto-RP on the 3750 or the 3845 ?
We have 2 Cisco 5508 WLCs, each wtih 50 licenses. What I would like to do is split the 50 odd APs between the 2 controllers load balancing the traffic. If a controller goes down or there is a break in the path all APs would failover to their configured secondary controller. So far so good.
However there seems to be no way to 'replicate' the configurations between controllers unless I setup HA , but as I understand it HA is Active /Passive, so essentially, unless you get a failover situaltion, completely 'redundant'.
Is there a way or either replicating between controllers automatically with out HA, or is there a way of making HA Active / Active?
I have two 5508 and one WCS server, the controllers are in one mobility group.Now I have to change the management IP addresses on the controllers. What are the correct steps to do this?
View 9 Replies View RelatedI'm looking into upgrading our 4400 series controller to 5508's. Currently we have a few sites that have 8-9 4404 100AP controllers and I'm looking to condense these down to either 3 5508-500 or 5 5508-250 depending on cost. I'm wondering what a good port to AP ratio is for controllers with licenses that can handle over 100 AP's. I know the general rule of thumb is 25 AP's per port, but that seems to me to be 4400 way of thinking. I'm trying to also reduce the controllers overall footprint, i.e. ports on the uplink switch, power consumption, rack space etc.

We are installing a set of 5508 controllers at one site in Tennessee. At another divisional site we have another controller that covers that division.
Both sites utilize the same DNS structure and would like to use the DNS entry CISCO- CAPWAP- CONTROLLER entry for bringing new AP onto the controllers at their sites, how would we go about configuring this?
I have 2 WLAN controllers, a 4400 series and 5500 series controller. The 4400 series has 100 seat limit on it, with 74 Access Points currently connected. The 5500 series has a 250 max, but we bought it with only 50 licenses, and it is max'd out at 50.The 5500 controller is the controller that has a DNS entry so that the Access Points will know to find that controller as they're being added. BUT, because we've reached our limit of 50 licenses, I'd like to be able to set the 4400 series controller to be the controller that new Access Points try to connect to. By going back to the 4400 as the controller that new Access Points connect to buys me time to plan for more licenses on next years budget for the 5500 controller.

I have a cisco wireless environment running NCS with a wism, two 4400's, and now two 5500's. The bulk of our AP's are 1131's, however we are now ordering and using 1142's and 3602's. We just added the 5500 controllers in preperation for a large deployment of 1142's. What I would like to do is have the system setup so that the the 1142's will default to the 5500 controllers. Since the wism and 4400 wont support the 3602's its not really an issue for them. I'm trying to find the best way to accomplish this.

View 5 Replies View RelatedCurrently we do not have multicat routing enabled on either of our 2x Sup720-10G 6509 Switches. We have no intention of doing so either. I am looking for clarification on how mutlicasting operates within a Vlan.

Vlan25 is up, line protocol is up

we do not want to disable IGMP due to this one concern that I can't find documented. If we disable IGMP snooping on the vlan, what happens to multicast packets with a TTL > 1. Do they get flooded to the entire switch and all Vlans? Or does it stay within the Vlan?
It act's about the CISCO WC210 WLAN Camera.
We are using the WVC210 WLAN-Cameras (URL), this camera has a web server, so is accessible over a normal web-browser, to see the video transmission.
We just set it up with a normal WLAN-Router, so the camera is connected wireless to the router, and this router is connected to the internet (WAN). With the cisco video-software or the web-interface, it's now possible to stream the video.
Now we like to stream the Video on our Website, so people what visit our site can take a look at our company and so on.We are able to stream the Video with the MJEPG-Format, like the camera web-interfaces offers...
The problem is, with normal ip-transfer method, each user would connect directly to the camera and increases the data-transfer, the internet-connection will than overload easily.But the camera supports multi-casting, so the camera only transmit one data stream and all clients connected to this stream will receive the packages.
Our problem is, we do not have any knowledge about multi-casting and how it works, the camera has a normal ip-address and a pre-configured multicast address with group name, so how can we connect a client to this multicast group, without increasing the data-transfer with each new user? Would you recommend us to use the multicast function of this camera or put a server between the camera and the website?
How we can set up this multicast service and easily get a player for the stream on our website, without using many plug ins or special apps ?
