Switch configuration for AP's

We are trying to install a 2106 controller with a few 1261 AP's which we have downgraded to Lightweight.
We are getting our head around the 2106 config but am unsure as to what config to put on the switchport the AP's connect to.
As far as our reading goes it is best practice to plug the AP's into a network swtich and trunk vlan's from the switch to the controller.
Bit confused about the way the AP's connect to the switch.
Thanks

Hi,
As I understood ... you need to map existing vlan subnet with your wlan ...
you will have interfaces which you first need to configure on your controller .
1) Management IP of wlc
2) AP- manager
3) dynamic interface which will be used to map the vlan with respective wlan
4) virtual
procedure :
1) if you do not have dhcp seperate configured , first you need to create vlan then configure svi interface with ip address and  dhcp pool for your ap to get ip address in your l3 switch which is connected to your controller with default-router command which will point to your switch
2) login to your controller through console and configure the management IP address
command  : WLC( config ) > interface address management ... ip address... mask .... gateway ( it will be your switch )
configure AP-manager interface with above command with ap manager option ..
Now switch side you configure the one port which is connected to your controller as a TRUNK
connect ap to any port which will configured with above vlan which you have configured in l3 switch
Now AP should get registered and then follow below procedure for getting client connected to respective WLAN
3 ) once you configure login to gui of controller and configure dynamic interface with existing vlan subnet and give the dhcp server ip address if you have or else configure the dhcp pool for users also.
4) go to " wireless " option
5) select the respective wlan and map the vlan with respective dynamic interface
check whether clients got ip address.
please let me know ........ if you have doubt about it

  • Switch configuration for LAPs

    A local mode LAP is broadcasting WLANs that use VLAN10, VLAN20, and VLAN30.  The switchport the LAP is connected to is configured in access mode.  Do VLANs 10, 20 & 30, need to be configured on the switch? 

    No,
    You need to configure the WLC port as trunk and allow these vlan to this port.
    Example:
    WLC:
    interface GigabitEthernet1/0/1
    description Trunk Port to Cisco WLC
    switchport trunk encapsulation dot1q
    switchport trunk allowed vlan 10,20,30

  • Switch port configuration for 3500i AP

    Hi,
    We are due to install a brand new enterprise WLAN based on the WiSM2 platform, 3502i AP and WCS. The APs will be plugged into the 2960S-24TPS-L.
    I have scanned over all documentation and cannot for the life of me find a recommended switch port configuration for connecting the AP to the switch in terms of speed / duplex etc. For example, should I just configure the port to auto detect, or is forcing the speed / duplex the way to go. I could also do with knowing other best practice configurations for AP connectivity.
    Any help would be greatly appreciated.
    Chris.

    The AP comes online with just auto detect, but I want to know if there are any benefits to forcing this to 1Gbps / Full duplex, or even if this is the right way to go. I suspect auto detect is the best method.

  • WAAS Configuration for 3750 Switch

    I am configuring a 3750 switch with 12.2(52)SE according to:
    (from https://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_52_se/configuration/guide/3750_scg.pdf )
    This example shows how to configure SVIs and how to enable the web cache service with a multicast group list. VLAN 299 is created and configured with an IP address of 175.20.20.10. Gigabit Ethernet port 1 is connected through the Internet to the web server and is configured as an access port in VLAN 299. VLAN 300 is created and configured with an IP address of 172.20.10.30. Gigabit Ethernet port 2 is connected to the application engine and is configured as an access port in VLAN 300. VLAN 301 is created and configured with an IP address of 175.20.30.50. Fast Ethernet ports 3 to 6, which are connected to the clients, are configured as access ports in VLAN 301. The switch redirects packets received from the client interfaces to the application engine.
    Note Only permit ACL entries are being used in the redirect-list; deny entries are unsupported.

    Question:  How do I configure my WAE to play nicely with this switch?

    Hi James,
    Here is the link to WCCP config part on WAE:
    http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v441/configuration/guide/traffic.html#wp1041742
    In your case, if my understanding is right, VLAN300 is where you want to connect WAE and WAE is also L2 adjacent. if that is true, here is the config you need on WAE:
    wccp router-list 1 171.69.198.100
    wccp tcp-promiscuous router-list-num 1 l2-redirect mask-assign l2-return
    wccp version 2
    Please note that 3750 supports L2 redirection only with redirect IN statements on 3750 interfaces connected to servers and clients.
    Hope this helps.
    Regards.

  • Is it possible to run TWO parellel configurations for one Object??

    SAP Gurus,
    We have a strange requirement from the client to have to configurations established in the system for one configuration object.
    Without taking much of your time let me paraphrase the requirements.
    The client is having two different types of putaway strategies in their current business process. And they toggle between these putaway strategies by reaching out to their production support group and they make configuration changes to have the other put away strategy
    One Step Putaway: GR area --> High Rack Storage
    Two Step Putaway: GR area --> Interim storage (area at the end of each aisle of high rack storage) --> High Rack
    Client wants to have two parallel configurations for both of these put away strategies and needs an ability to switch from one to another. This switching ability should be accessed from SAP screen without any IT intervention (no configuration)
    -  Switching ability should allow the warehouse manager to change from one step to two step put away strategies without any IT intervention.
    -  Switching ability should be accessed my SAP Screen (Z-transaction or something with a radio button to toggle around)
    Is it possible to have two configuration made for Putaway Strategies and switch them on/off depending on the warehouse needs??
    Your invaluable feedback on this will be highly appreciated.
    Thanks again folks,
    Dhaval

    Q1--I don't believe it is possible. An organization can have multiple licenses tied to its main email address, for example, but then they are assigned to the individual users.
    Q2--Yes, you would just need to log out of your account within the CC desktop app prior to logging in on the other account.

  • "Server either does not have a virtual switch configured or none of the configured virtual switches have an IP address assigned" error driving me nuts!

    OK; have been trying to setup a test VM based RDS deployment for a few days now with no luck.
    this error mentioned above:
    "Server <server name> either does not have a virtual switch configured or none of the configured virtual switches have an IP address assigned" error is driving me nuts!
    I have removed and re-added the RD Virtualization Host role numerous times, each time having the "create a virtual switch" checkbox selected, but it did NOT create any virtual switch.
    I created the external virtual switch manually and tried to create the desktop collection again, no luck with the same error.
    a few questions:
    1. you don't assign IP to a switch! you assign IP to Network Interfaces. why does the error puts it like this?! it is technically wrong.(yeah yeah I know all about how you'd assign IP to managed switches in real world to telnet into them and manage them.
    you know better than me that it is not the case here!)
    2.the RDS Virtualization hosts are using their wifi card as the card for the virtual switch. could that be the reason? I even disabled their unplugged wired NIC just to make sure that the wifi is the only available option for the RDS wizard to use for the
    virtual switch creation; but it didn't use it and it didn't create any virtual switch automatically.
    3.if WIFI nic is indeed the reason, is it your suspension or an official documents is there somewhere stating so (that the WIFI NICS on a Virtualization hosts are not supported as the hub for a virtual switch).
    4.what are the properties of the virtual switch the RDS requires? does it have to be external? why can't it work even with my manually created external switch?
    5.how would I fix it?
    P.S: the environment is made up of 2 laptops, having windows 2012 R2 trial installed on them, using their wifi to connect to the out world. no cable is plugged into their wired NIC card.

    Hi,
    Thank you for posting in Windows Server Forum.
    The simplest short term solution was to connect each computer to a small switch that had no other connectivity. This brought up the link light on the external NIC and allowed the creation of the collection to complete. You need to use an external switch. You
    can create one external switch which might fix the problem.
    Please check below article for information.

  • ISE 1.2, Supplicant configured for 802.1x but need to MAB

    I posted this yesterday but deleted the thread thinking I had fixed the issue - alas I was wrong. In summary I have a scenario where I am doing wired 802.1x and also wired MAB/CWA. The issue is that a certain number of external/BYOD hosts have supplicants configured for 802.1x at their "home" organisations which for obvious reasons can't authenticate on this network. The idea is that MAB and CWA become a fallback but these hosts in question don't efficiently fail to MAB.
    If the host has validate server certificates enabled (and doesn't have our root selected) then 802.1x fails and goes to MAB as per the tx timers etc. Hosts that don't validate certificates essentially fail authentication, abandon the EAP session and start new... this process seems to continue for a very long time.
    Does anyone have any similoar experiences and if so can you provide some info? I am looking into tweaking 802.1x port timers to make this fail quicker/better but am not confident this will fix the issue.
    Thanks in advance

    Maybe the held-period and quite-period parameters would help.  I would not change the TX period to anything shorter than 10 seconds.  Every cisco doc that I have ever seen has said this same recomendation and I can tell you from experience you will have devices at times that will authenticate via MAB when you dont want them to if you decrease lower than 10 seconds. 
    Read this doc for best pratices including the timers listed below.  
    I hope this link works.  http://d2zmdbbm9feqrf.cloudfront.net/2014/eur/pdf/BRKSEC-3698.pdf
    If not goto www.ciscolive365.com (signup if you havn't already) and search for
    "BRKSEC-3698 - Advanced ISE and Secure Access Deployment (2014 Milan) - 2 Hours"
    Change the dot1x hold, quiet, and ratelimit-period to 300. 
    held-period seconds
    Configures the time, in seconds for which a supplicant will stay in the HELD state (that is, the length of time it will wait before trying to send the credentials again after a failed attempt). The range is from 1 to 65535. The default is 60.
    quiet-period seconds
    Configures the time, in seconds, that the authenticator (server) remains quiet (in the HELD state)
    following a failed authentication exchange before trying to reauthenticate the client. For all platforms except the Cisco 7600 series Switch, the range is from 1 to 65535. The default is 120.
    ratelimit-period seconds
    Throttles the EAP-START packets that are sent from misbehaving client PCs (for example, PCs that send EAP-START packets that result in the wasting of switch processing power). The authenticator ignores EAPOL-Start packets from clients that have successfully authenticated For the rate-limit period duration. The range is from 1 to 65535. By default, rate limiting is disabled.

  • Dynamic configuration for the application

    I'm a newbie and trying to evaluate JSF. I took part in a project with struts framework and i could say i don't like struts cause of some limitation and i suspect that JSF has the same limitation. First of all, there are JSP pages. I can't use JSP pages/templates stored somewhere else except web application. I'd like to store my templates in the database. This will give me ability to add/change/remove jsp page without redeploying war-archive. Yes, i can use exploded war-archive and add JSP pages straight into file system, but i don't like this way. Next problem is the configuration file like struts-config (faces-config, whatever). I have to write down all my navigation logic and beans mapping to this file and it's really annoying me. This kind of project requires dynamic configuration for the all web application and i'd like to add/change/remove pages, beans, actions without restarting/reconfiguring webapp. Today, I looked thru documentation and source code and found that FactoryFinder class could use my own classes but i'm not sure it will be enough for the dynamic configuration for the beans. In any case, it's a huge problem with the templates.
    Right now i'm thinking about 1(one) JSP with XML/XSLT rendered HTML content and JSF for event/action handling. I mean, i'll use XSLT to render dynamic content and JSF for dispatching events. In that case i have to render form tag names in the HTML as JSF engine (i'm not sure if it possible). If it will take a lot of time to do this i'll have to switch a home-grown framework.
    So, i really need advices how to implement this sort of dynamic behavior in the web application.
    regars,
    anton

    A lot of what you're seeing are genuine limitations, but happily, JSF is so pluggable that you can overcome them.
    JSPs are problematic in exactly the way you describe - unless your app server has support for pulling JSPs out of a database, etc., you're SOL. JSF, however, lets you use something other than JSPs by replacing the ViewHandler. That's a fair bit of work, but it is doable.
    For navigation logic, you'd replace the NavigationHandler. As long as you're willing to write the code that can pull navigation rules from an external source, life is good.
    For managed beans, all you need to replace is the VariableResolver - again, if you can pull the rules from an external source, you have full control.
    This is all far from easy - and it's a huge amount of work for one person - but I'd imagine these pieces will become available from various sources. A core goal of JSF 1.0 was making the framework as a whole pluggable so that others can innovate on top of the framework.

  • Optimal configuration for Cisco E3000 Router

    Hi All,
    Following are the details of my current home network setup, I would like to hear more recommendations and drawbacks of this setup.
    ISP has provided with a Cisco  DPC3825 DOCSIS 3.0 Gateway which has 4 Ethernet ports and a wireless networking but only 2.4 GHz.. This router is connected to the cable CPE box to internet. I have enabled the Firewall features of this router and disabled the Wireless network. This has also the DHCP server running. 
    The Second router is a Cisco E3000 which supports 2.4 GHz / GHz wireless networking. Connection to gateway is made via the 1st Ethernet port of gateway and then to the Internet port of E3000 router. I have connected my wireless devices to E3000 with GHz wifi lan. This router also has the firewall activated and DHCP server running as well.
    Both routers have WEP2 Personal / AES security configured. Currently these two devices are on two different IP ranges ..etc gateway is 192.168.0.1 and e3000 is 192.168.1.1.
    The E3000 is primarily configured for my online video for TV (Panasonic Vireacast). Please let me know if this is the best configuration or any other possible options.
    Thanks,
    RG

    This configuration is called LAN to WAN configuration and this is the best configuration considering that you want to behave both the router as a router.
    Because the other confiuration would be LAN to LAN then you can only use 1 router as a router and 2nd router as a switch.

    Hi all,

  • QoS Configuration for NME-AIR-WLC

    Hello,
    I have a question on the correct QoS configuration for a VoIP deployment. I have followed the steps referenced here but have two questions..
    1) The last recommendation in the list is to set DCA channel sensitivity to High to avoid changes during business hours. I think this should be Low? The manual states "Low—The DCA algorithm is not particularly sensitive to environmental changes."
    2) The recommendation is to trust dscp on AP uplinks and to trust cos on the WLC uplink. However I can't find any configuration guidelines for configuring QoS if the WLC in question is an NME hosted in a 2921.
    2a) The link between the switch and the 2921 is an 802.1q trunk so should I trust cos on this link rather than dscp?
    2b) What configuration should be on the 2921? Create a policy-map and apply it to the uplink port?
    2c) Should there be a service policy assigned to the In1/0 interface for the WLC itself?
    Any thoughts appreciated.
    Thanks,
    Dave

    Well I appear to have answered question 2 after I stopped being lazy and did some packet captures.
    No configuration required on 2921 as packets captured from In1/0 and Gi0/0 show correct DSCP markings on RTP and SCCP packets.
    Would still be interested to know on question 1 though.
