--- I have 2 WLC's 5500 that I have to set up on my network with the same configuration except I am not sure that they can be load balanced.
-- My only thought is to take a full class C and on each WLC set up a /25, thus each device can provision 120 IP's
--- This seems a bit archaeic, but is there anything else smarter to do? Can they be load balanced?
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?
Our controller get freezing every week at least twice, and do not know what is the reason. I am attaching the log for you to look at it. Last time happened was yesterday at around 13.00 pm.
View 15 Replies View RelatedI 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).
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.

What is the best way to load balance traffic between an FWSM and ASA 5520? Both are attached to a 6509-E (in seperate VLANs). The problem is the FWSM doesn't support any dynamic routing protocols (in multi context mode). So with my limited knowledge I don't see a way to do this.

I am using 192.168.1.1 as database server in head office. my branch user are more than 500. all user hit at 192.168.1.1 for database. Now i want to NAT with application server 192.168.1.50 and 192.168.1.51 with load balance As some user hit 192.168.1.1 form branch but traffic go to 192.168.1.50 and some users traffic go to 192.168.1.51.
I want to do it in My core router (Cisco 3845) in Head office. How i do these two things ?
So I can fail over my NAT and IPSEC VPN (DPD). I am curious can I load balance my WAN links too?
I have a route map that is used for fail over, I just can't quite think how I would load balance the links

ip nat inside source route-map efm interface Vlan3 overload

I have two 5508 WLCs. Both have APs attached to them. If I create a guest account with the lobby administrator on one, will that user account be able to log in to the network if the client is attached to the ohter WLC? So far, I have found that I need to create the same user on both WLC's, in order to have the user login.
View 2 Replies View RelatedJust recently upgrade our 2 5508 controllers from 6.0.199.0 to 7.0.116.0. Since that upgrade, I have a handful (8 to 10) of wireless laptops that now refuse to associate to any access points. The thing these laptops all have in common is some variation of the Intel Wifi Link AGN cards. I have about 200 other clients out there working just fine.
I've tried everything under the sun that I can think of. Patches, drivers, the whole sh'bang.
Is there a known issue with 7.0.116.0 and these particular cards?

View 1 Replies View RelatedI have problem with VPN and Load Balance at the same time.VPN (Gateway to Gateway) between two RV042 routers is working fine with only one WAN or two WAN's with Smart Link Backup. If i switch to Load Balance communication through VPN is almost impossible.
I have postgres server (port 5432) in first location and clients in another. Clients cannot connect to server or lose connection after while. This is example, but every communicaton except ICMP over VPN with Load Balance enabled is faulty (file sharing, RDP...). Everything works fine using public IP and port forwarding or VPN with only one WAN.
If i understand it correctly Protocol Binding should affect only "normal" communication (outside of VPN), but it looks like VPN communication is also divided between WAN1 and WAN2. Of course this cannot work this way because VPN works only with one WAN.
Another question - is it possible to bind communication TO selected target port with RV042 Load Balancing to selected WAN?

View 1 Replies View RelatedWe want to us an ISA570 and load balance between two isp connections, two of our switches will be standalones and not connected to one another. One switch will be for data and another VOIP/Data. The ISA will also do NAT and we need to make sure that the VOIP network can get out to the first isp. I assume we will need a static route for that to make sure it goes out the right isp. I just don't know if routing mode needs to be enabled in order to specify a static route, because I heard you can't have NAT and do routing mode at the same time.

What might be the default gateway?Can i create a serverfarm with two rserver with different subnets?
I configured a RV042 to load balance 2 WANs. It appears to working well but I would like a 2nd opinion as to whether or not I chose the proper settings to accomplish the task.
1. WAN1(ISP1) is the existing internet connection(1.5mb T1). I have a block of static IPs with ISP1.
2. I added ISP2 to the RV042's WAN2 connection to increase bandwith (10mb). I only have one static IP on ISP2.
3. I want everyone on this router to use WAN2... well... almost everyone... for the most part.
4. I want to keep WAN1 active on this router because there will be periodic inbound connections using static IPs (from ISP1) that are setup with one-to-one NAT. I also have a voicemail system that needs to continue to use ISP1's email relay (SMTP,25).
Anyway, I was able get the outgoing traffic that had to remain on WAN1 working with protocol binding. In order to get the router to use WAN2 for pretty much everything else, I set it for load balancing and set "Max. Bandwidth provided by ISP" for WAN1 up & down kbits/sec both to 32 (very low). I left the WAN2 up & down settings to the actual speed of WAN2.
The result is very low traffic on WAN1 and lots of traffic on WAN2 which is what I wanted. Did I do this right? Is there another preferred method to accomplish this.
Is 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.
