Cisco :: Configuring Trunking And VLANs On A 2100 Series Wireless Controller?

Oct 4, 2011

We have 4 1142N LAPs that I want to divide between an internal wireless and a guest wireless network using the controller.  Currently all of the APs are on an established internal network, but I want to migrate one over to a test guest network before buying more LAPs to augment the networks further. Currently the port connecting to the WCS from the 3560 switch is configured as an access port using VLAN 10.  Whenever I make it a trunk port carrying VLAN 10 as well as the other ports we will be using for the guest and ap-manager networks, I lose connection with the controller.  To me this implies that the port on the controller is configured as an access port as well.  In the documentation I found for the controller it states that by default the ports are al configured to be trunks, but it appears as though something was changed by the previous tech.  All of the APs are connected to other switches, not to the controller itself.
1) How can I get the port on the controller back to being a trunk port

2) Can I use the internal DHCP server for the guest network if the subnet is different than the management subnet, or will I have to use another external server and relay/proxy it through the controller to give guest clients IP addresses?

Cisco :: Test Fast Roaming Using A Cisco 2100 Series Controller And 2 1140 APs?

Jul 20, 2011

I'm trying to test fast roaming using a Cisco 2100 Series controller and 2 1140 APs. The initial authentication succeeds fine and the wireless connection works ok using WPA2+CCKM and LEAP with a Cisco ACS radius server.The problem is that the client does not attempt to preauthenticate with the other AP because the RSN Capabilities IE in the AP beacons and probe responses do not set the RSN Preauthentication capable bit. I can't figure out what it takes to get the APs to indicate to clients that it can do preauthentication. I'm been crawling through all the documentation I can find, to no avail.

Cisco :: Setting Up Wireless LAN Controller 2100?

Feb 7, 2011

I am having trouble on setting up a WLC2100 ver 7. we need to implement a private and public network. private network authenticate to IAS - RADIUS (windows server 2003 server) while the public network is open but when a client connect to AP it will redirect to a 3rd party web athentication - HotSpot Server. the challenge is we want to broadcast a single SSID.

1. when a user/guest connect to the AP a radius server will authenticate thru IAS - Radius.

2. when a user is authenticate via radius a dhcp server will give an ip address of the private network.

3. if the user is not authenticate a dhcp server will give the public ip address and netowrk traffic must go to a different VLAN.
my question is, is it possible to broadcast a single SSID for the two network? is there a document which is related to our scenario?

Cisco :: 2100 / Two Network Connections And One Wireless Controller?

Jan 29, 2013

In the near future my company is looking into the option of adding a second network connection (exclusively for customers visiting our facility) to our pre existing WLAN network. We are currently using a Cisco 2100 series Wireless LAN Controller and probably 6-8 APs. Our main connection is made up of 4 T1 lines and the second connection will more than likely be a cheap DSL connection. I'm wondering if this technology supports two separate connections on one controller and APs. For example, is there a way within the controller web interface to separate what is currently our "Guest" connection from the main Internet line? I was thinking of just plugging from the DSL router directly to the controller and save the hassle of changing routing and VLANs.

Cisco Switches :: SG-200 To 887 Setup Trunking Between These 2 Devices For Multiple VLANs

Mar 28, 2012

We have a Cisco 887 router and a Cisco SG-200 switch.We'd like to setup trunking between these 2 devices for multiple VLANs on the switch to be made available on the router.
With previous routers, you could set the router up in the configuration 'router-on-a-stick' and VLANs worked like a charm but the 887 no longer support sub-interfaces.So how can you get trunking working between the 2 devices?
Is there a VTP configuration menu for the SG-200 which we can setup in order for it to talk 'VTP' with the 887 router??

Cisco Switching/Routing :: Configuring 4507R For LACP And Trunking?

Apr 3, 2008

We're trying to configure our Cisco 4507 (Supervisor Engine IV) to allow a new Dell server with a pair of Broadcom 5708 GigE NIC's to aggregate its NIC's to give us a 2gbps link to the switch.
So far we seem to have got the team and LACP up and enabled, but the adaptor that the Broadcom Admin Util creates for the team is only showing a 1gbps connection where I would have expected it to show as 2gbps.
The individual NICs show as connected at 1gbps. We're not Cisco experts so are struggling on how to get the 2 NICs to aggregate.
On the server side we've done nothing other than create a team using 802.3ad LINk Aggregation using LACP.
This is what I think the relevent output from "sho conf" is, more available if needed.

Cisco Switching/Routing :: 3560 CG Port Goes Down When Configuring Trunking

Jan 31, 2012

I have a 3560 8 port switch.  Int gi0/9 is trunked to another switch downstream.  When I try to configure int gi0/10 to trunk to a switch upstream the interface on the switch goes down and I have to either reboot the switch or plug directly into the switch and telnet into it to turn off trunking on the interface.  When I configure trunking on the interface on the upstream switch that connects to this interface the same happens on that switch.  The upstream switch is a 3750 with 12 sfp ports.  Several interfaces are trunking to other switches from this switch.  Spanning tree is not configured on the 3750 at all , and is not configured on either gi0/10 or gi0/9 on the 3560.  I was consoled into the 3560 during a reboot after the interface went down, a message came up that said something like "Spanning Tree returning gigabit ethernet 10 to constant state"  Why would I get this message if spanning tree is not enabled on the gig ports on either end of the trunk? There is no loop to require spanning tree to shut down an interface.  I have several other 3560's configured as I would like to configure this switch and they are trunking without issue.

SG300-20 - Picking Up 16-24 Port Gigabit Switch That Supports Trunking / VLans For Home Use?

Mar 11, 2011

I've been looking at picking up a 16-24 port gigabit switch that supports trunking, vlans etc. for home use.

I've looked at the Cisco SG2/300's, HP 1810g-24 and the Dell 2816 and 2824 switches, and it seems like the Cisco's are the best buy (layer 3'ish features, same price as the HP) but there isn't much about them.

Cisco Wireless :: Configuring RADIUS Server On 2500 Controller

Dec 3, 2012

We have recently installed Cisco for our wireless solution. We are an education and are looking to let staff and pupils bring their own devices. The route that we are planning to take to let them join the school's WiFi is to implement a RADIUS server so that they can authenticate with their Active Directory username and password. I have tried to test the solution but so far without any success. I am using a Windows Server 2008 R2 as my NPS server, I have setup the Cisco controller as per below:
Security Tab | RADIUS | Authentication - I added my windows server there and the preshared key, the Network User and Management is ticket and the server responds to a ping command,In the WLANs Tab, I selected my test WLAN and under Security | AAA Servers I selected the RADIUS server that I configured in the Security TabI then try to logon to my test WLAN and on the Cisco WLAN controller I get the following error: AAA Authentication Failure for UserName:test User Type: WLAN USER 
Before trying to tinker with policies on the Windows Server I was wondering if the RADIUS is correctly setup on the Controller or have I missed something obvious?

The controller is v6.0.199.4
Every time I have set these up in the past they have been pretty straight forward.  I haven't gotten too deep into the config on the WLC becuase I don't want to cause more issues.

Cisco WAN :: Configuring Two VLANs On 871 Router

I use the cisco 871 router as a firewall to my home-office. I have configured two vlans for each seperate port. That is, FE0 configured as VLAN 10  ----> connected to Layer 2 Switch,  FE1 configured as VLAN 20 ----> connected to another Cisco Layer 2 Switch,FE2 not in use, FE3 not in use and FE4 is connected to WAN.I got 100Mbps speed from the ISP, but I can see that I only get 50mbps even connected to VLAN 10 or VLAN 20.Does configuring two VLANs on Cisco 871 router divides the bandwidth (to Internet) into half?
