Cisco Wireless :: 2504 - Redundant NCS Server Connected To Single WLC
Apr 15, 2013
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?

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 ?

I tried searching through the threads but didn't see anything on this. Recently bought the E4200 so that when guests come by they can use a separate network instead of mine. I have guest network set up for one user but I am able to connect more than one computer to the guest network.

I have a 2504 WLC and 1042 ap's. Everything worked great in my test enviroment (of course). Now when I want to deploy the wireless, the ap's are not getting and ip for the windows dhcp server.
I have option 43 configured in dhcp, sub option 241>ip address of the controller
I have my A record in dns, cisco-capwap-controller.

I want to know if its nessary to install Certificate authority on your radius server. If we have a CA server already in the domain can we use that for this purpose or we have to install certificate authority on our DC.

setup a DHCP server on a WLC 2504. I'll try to resume my configuration:
I have 2 networks: inside users (vlan 1) and external users (vlan)
My controller uses the port 1 to connect to the switch, which has a trunk with WLC.
I have two routers, one using vlan 1 (192.168.3.0/24) and one using vlan 10 (200.X.X.X). All ports to these routers are access ports on their respective vlans.
I have 2 SSID, one for inside, other to outside. Inside is working very well.
To the outside I created a DHCP escope and already set the IP of the management interface 192.168.3.119.
Managemente interface (vlan 1 inside): 192.168.3.119/24
Outside interface (vlan 10): 200.X.X.195 - Default gateway 200.X.X.X.193
I alredy checked the DHCP Proxy in Advanced option.
See the output of the debug client:

I have already raised this discussion on "LAN, Switching and Routing" group. But I guess this is the right group for my queries. So I am sending my queries in this group again.
We are using CSS 11503 with one 16FE line card. We have connected 3 servers with redundant link. So FE1-2 in Server1, FE 3-4 in Server2 and FE5-6 in Server3. Our system team has configured APA in their servers as they are using HP-Ux.
1) Do we need to do any configuration at line card.
2) Do we need to do ether-channel at loadbalancer end. if yes, can you share me any cisco doc on how to do it.

Ok, so with my WLC2504 implementation, I use the 4 ports to physically segment my wireless networks. Here is my setup:
Port 1 (Management) - Internal IP so I can manage the WLC from our internal network (Untagged)
Port 2 - Connected to our core stack and tagged with VLAN 14
Port 1 and 2 are both connected to the same core stack
Port 3 - Connected to a RV016 Linksys which is connected to our fiber connection to the outside (Untagged) - External connection for laptops
Port 4 - Connected to a Linksys wireless router (with wireless disabled) (Untagged) - External connection for smartphones
The TAC engineer I talked to just told me that I can only have one untagged interface on the WLC. If they are physically connected to different switches, thus physically segmenting the network, should it matter?
The wireless works just fine. What I am having issues with is getting a client that is hard-wire connected to the RV016 to get a DHCP address from the WLC.

Nexus infrastructure is pair of N7K switches, with dual homed 5K/2K devices connected, links use vPC. They want to extend vlan's from the 5K/2K side across a L2 path into another DC, this path is only connected into one of the N7K switches, call this 7K switch A.I'm concerned that packets from the 5K/2K side back to the remote DC could get dropped due to the vPC loop dectection process. If a packet from the 5K/2K side traverses the path into the same N7K (7K switch A) as the L2 extension, I dont see a problem. But, if the etherchannel load balance in the 5K sends traffic to the packet to N7K B, in order to get to the L2 path extension to the remote DC the packet gets forwarded across the vPC. My understanding is that this packet will get dropped by N7K A as its local L2 path to the remote DC is up, is this the case?I see a solution is to plug the L2 path into a 2K, but before I suggest this is my understanding of the loop detection process correct?

I am troubleshooting a fiber connectivity issue.Now I have two switches, one is 3750, and another is small biz 300 series switch. Both switch has a single mode smf gbic. Now I have two swtiches face to face and connect with a single mode cable. Do you think if I would get a link light on? Both ports are no shutdown.

Can the 2504 WLC be configured to work with one RADIUS Server for Authentication of Management Users and with a second server for 802.1x EAP-TLS certificate authentication for the end users.
Management Users will authenticate on RADIUS Server 1.Wireless End users will request 802.1x EAP-TLS authentication certificate from AAA server 2.

I'm looking to implement a single proxy server for two different VLANs. Both VLAN have outgoing traffic configured through different ISP i.e. traffic for users on VLAN1 is routed through ISP1 and traffic for users on VLAN2 is routed through ISP2. Inter-VLAN communication is enabled. The proxy server should route internet traffic for users in VLAN1 through ISP1 and for users in VLAN2 traffic should be routed through ISP2.

I just want to keep one PC as a server and one switch connect to it (For LAN). I want to connect multiple client/screen to that server, so I can use single servers for multiple screen/client.(Client machine will not have any CPU, they will utilize servers memory.)

Actually not randomly. It's normally after weekly reboots. This causes the Great Plains DB to be locked to 1 person, so other people get errors.
Sometimes I can just unrestrict access, other times it's grayed out and I have to drop the DB and restart the services to take it out of single user mode.

I have successfully set up a windows 2008 box as a Radius server and use it to authenticate VPN users against ta AD database.I have also set up a similar policy that permits authentication for management purposes to all my networking devices (routers,switches and the ASA).Both policies work fine.Of course I don't want every VPN user to have administrative access to the ASA and every other device on my network.How can I discriminate between the 2 groups (VPN users and Network administrators)

I have 2 servers, one active, the other standby, both will be using the same IP. If the active fails then a re-patch for the standby to make this the active. I understand that i will need to clear the arp & maybe mac address table on the 6500 for the new active server to work, as the failed server will have its mac address on the 6500,.
is there a way around this so i dont have to clear the arp cache & clear the mac table? [code]

I have an ASA 5510, one public IP address on my outside interface, an internal email server and a private network.I would like...
1: Users on my private network to be able to access the internet (PAT them to external outside address)
2: Email to be delivered to my MX (my single public IP address translated back to my internal email server.
i.e. can I share my single public IP address to serve translation in both directions (private users surfing the Internet (in-to-out) and an outside to inside NAT for email) ?
Email (MX) = 1.2.3.4
Public (outside) address = 1.2.3.4
Email server internal = 10.1.2.3
Internal private subnet for users = 10.0.0.0/8

We have multiple RA VPN groups on a 3845 router.RADIUS authentication is currently happening between the 3845 and a single Windows 2008 server. We have a specific windows group that AD users are members of, and they are allowed to connect via VPN.
I'm creating a new RA VPN Group, which should only allow different AD users. Is it possible to create another RADIUS association to the same server, or do I need to authenticate against a different Windows server?

I 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).

I've configured a lot vpn server for 857/1800, etc. But this has never happened.I configured 881 as VPN server using CP.Shared key, local group and local user authetication with split route.Local pool 192.168.100.1-254? I have acl for telnet which allows local pool IPs.I have acl to deny local network to local pool IPs for NAT.I've deleted the whole settings and re-run the wizard. It's still the same thing. I can connect from the VPN Client, but no traffic going through. The problem to me is isakmp with DPD. But why it is dead? Why no response from the server? If it is an error, why connection has no problem.
