SSID anchored

Hello

We have a couple of corporate Wireless LAN Controller (WLC 5508). They are used for corporate purposes. Now, we have added an anchor (WLC 2504) controller located in the demilitarized zone to offer access as a guest. We threw the anchor two SSID. The first is completely free with only internet access. It works very well. But we have a problem with the second SSID.

The other requires authentication. This authentication must be made through RADIUS. We don't have work and finally, we understood why. The authentication process is done by the controller from abroad. We have confirmed that this network as a point of capture. Foreign controllers do not know how to get to the Radius server. And we want to anchor the controller to be one who makes authentication. His IP address is the IP address that is accepted on the Radius server.

In all of literature, we read that it is said that authentication is always via the controller to default anchor. For example:

In an anchor - WLC foreign scenario, which WLC sends RADIUS account management?

In this scenario, authentication is always made by the WLC anchor. Therefore, RADIUS account management is sent by the WLC anchor.

-RADIUS server: in the WLAN security > AAA Servers tab, you controller anchor can set specific RADIUS servers to use, that your foreign controller does not care. Authentication is performed on the anchor, not on Foreign Affairs, you can call the RADIUS servers on the anchor and not on Foreign Affairs, no problem. It can also be a difference.

This is not the case in this way on our scenario. We have:

  • Layer Security 2 management of 'WPA + WPA2' keys and authentication set to the value "802.1 x."
  • Set us the RADIUS AAA Servers tab.
  • We took the version of the 8.0.132.0 software.

So we would like to know if any other configuration is needed to get the anchor being the source of the authentication process.

I thank very you much in advance!

Josu,

This is where your needs must be defined?  Encryption of the client to the access point is done only when you use the layer 2 encryption.  So that being said, the RADIUS is also done on the foreign controller to layer 2.  Therefore, decide what is the best solution for you. When I hear about erase the text when you anchor, I ask if encryption is required.  Generally, you anchor a SSID to a controller of the DMZ to access internet only so do you really care?

  • Cisco WLC SSID anchored several subnets

    Hello

    I have a requirement to land a SSID on a controller of the anchor but that AP customer connect I need them to receive certain IP address.

    Then...

    I have a LWAP called AP1 connection to WLC1, WLC1 uses WLC2 as the anchor for the ssid SSID1 DC. When a user connects, I want the user to get an address of SUBNET1. If a user connects to AP2 is also linked to the WLC1 I want the user to get an address of SUBNET2

    Now... If the AP is it is located directly on the WLC2 I could use groups AP to provide this feature, no one knows if its possible to combine it with anchor?

    Thank you

    RG

    Fix... You can't do what you are trying to accomplish. If you were doing 802. 1 x, you can use override AAA to assign users to a vlan, but other than that, the WLC cannot perform this task.

  • Type of SSID to deport the traffic from users of the Intranet of DMZ

    Hello

    We would like to use a pair of WLCs in the DMZ, to have the traffic of a specific SSID directly deported to the demilitarized zone.

    This might look like as a guest, but in our case, that it would be more a BYOD deployment, allowing devices mobile Internet surfing, but without having access to the Intranet at all.

    I found a good number of guide for the deployment of Cisco Guest access with anchors etc... but many are old, I did some research for BYOD but everything seems very general.

    About http://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Mobility/emob73dg/emob73/ch10GuAc.html

    Mobile devices will use x auth 802.1 with certificates or PEAP, so no portal, the webauth or sponsors in this context.

    I try to post my question here:

    On the DMZ WLC I need to create the same SSID that we have in the Intranet, but type SSID should be normal (WLAN) or the LAN or remote LAN?

    And if I am not mistaken, that I need to create a new interface that will be used for user data traffic, on the WLCs in the DMZ, this aspect should be settled on the SSID as well?

    Thanks for your support,

    One you want as an anchor, on this controller if you click on create it will appear as a local, for the foreign controller to highlight the address IP of the anchor to drop down and then click on create a mobility anchor.

    Given the DMZ as an anchor your controller.

    DMZ controller: Local

  • ISE foreign CWA / deployment WLC - missing user of anchor names

    I'm not sure if this belongs to the section mobility or security - I'll just give it a try here.
    I've set up wireless access visitor with Cisco ISE 1.3 (patch 2) and a stranger WLC / anchor of deployment (7.6.130.0).
    So far almost everything works fine - but I probably have a problem with logging Cisco ISE.

    In exploitation forest 'authentications Live', I see the authentication successful, but the identity of the column, it shows just the MAC address of endpoint.
    If navigation to the identity store of endpoint endpoint of comments is in the right group (guestendpoints) and when you look at the details of the endpoint, I can see the "portalusername" who created the user.

    If I click on endpoints active view (see attachment), I can see all active clients (Authz profile "PermitAccess"). I guess the user name of the client must be filled out there as well, no?

    Someone has an idea what is the cause for this? Or is the normal behavior?

    My rules of authentication are:
    If "wireless_mab" and "RADIUS: Called-Station-ID ENDS WITH comments-SSID" then use "endpoints internal" and continue if "user not found".

    My authorization rules are:
    1.) if GuestEndpoints AND (Wireless_MAB AND RADIUS: Called-Station-ID ENDS_WITH Guest SSID) then PermitAccess
    2.) if (Wireless_MAB AND RADIUS: Called-Station-ID ENDS_WITH Guest SSID) then GUEST_WEBAUTH
    The profile GUEST_WEBAUTH Authz defined the CWA and preauthentication ACL for the WLC

    The WLC I just configured the WLC foreign with the RADIUS (ISE) server and active authentication MAC the SSID.
    All parameters such as aaa-override and RADIUS of the NAC are defined. The defined RADIUS is set on "settler" to comply with the ISE

    According to my experience, this is the expected behavior.  The new workflow for the use case of comments starting at the point 1.3 of the ISE typically includes registration of endpoint, you're.  Your strategy for authz for post-portail of authentication (after the certificate of authenticity) needs the MAC address to use as the identity for permissions invited, not the guest credentials used on the portal.

    That being said, I would like to be able to see the username of the user portal whenever a registered endpoint point authenticates (until it is served using endpoint political purges, of course).

  • AP groups with anchor comments

    Hello

    I need to use groups of AP for guest ssid and this is a scenario of controller of anchorage. Is it possible to configure an ssid for comments and this ssid is put in different groups of ap in different VLANS on the controller local and anchored on the anchor comments controller? How can I configure this anchor? Can I put different corresponding interfaces on the anchor wlc and make several for different groups of ap dhcp scopes?

    concerning

    Joe

    Joe,

    Currently, you cannot base the anchor on the AP group.  It is based only on the SSID.

    Now, do you really need to split the guest in different subnets?  Or are you concerned about groups of AP?

    If you really want to break the prompt to different subnets, then you will need to create a different SSID on the inside and controller of anchorage.  Anchor, then link to the appropriate interface.

    If you are concerned about the AP group, don't be.  Everything simply because you use the AP group, doesn't mean that all the ssid of comments cannot bind to the same interface, they can.  You can even create a dummy interface on the internal WLC, so that if the anchor does not work, they do not have an address.

    See you soon,.

  • ISE 1.2 - begging CWA provisioning with anchor WLC

    Hi all

    Having a problem with supply begging via CWA on a controller of the anchor. I am able to connect through CWA and authenticate etc no problem, but when the device registration page it says "cannot connect to the network at this moment" - the mac address is filled but the said button try again. Once I click on retry it cycles back to the original comments Portal login page. In the section reports the begging failed provisioning message is "error trying to determine access privileges: failed to get the host name of the session cache."

    I tried the same policy without the anchor (ie the local controller) and it works perfectly. Interestingly enough if I manually register the device then connect first the portal comments, that it allows me to click on register and proceed to the provision of begging. I also tried installing anchor using peap and NSP redirection - this also works perfectly.

    I can confirm beforehand that firewalls, etc. is not a problem with permit IP any one between all parts of work - no blocks without drops etc. Politics is the standard CWA trustsec installation with Enable ticked self-supply. For what it's worth, I am absolutely confident with the config having deployed before - but without a controller of anchor.

    Stephen,

    I have worked with TAC customer account team to find a solution.  The problem is with the WLC anchor and the session not replicated.  I was able to get around by disabling account management radius for the ssid on the controller of the anchor, but when we look at the bug looks like an alternative solution is to disable fast switching ssid, which could cause problems with BYOD worldwide double ssid.  I still do test, but the accounting change seems to have resolved.  Bug ID: CSCui38627

  • Requirements of the mobility for the comments of anchor WLC group

    Hello-

    I always assumed that you cannot create a tunnel between a local WLC and an anchor WLC comments that are in different groups of mobility.   However, I was told recently (no more details) that it is possible.  So I put to test this.

    I'm trying one of my local WLCs SSID comments point to an anchor of WLC comments in a different group of mobility.   I have a forthcoming maintenance window and I'm looking to anchor clients on a campus at anchor WLC on the campus on the other for the customer service does not lower.   Each campus is that it's mobility group.   Trying to set up I went to the "mobility anchors" screen for the SSID guest on one of the local WLCs and I cannot add anchor WLC on campus on the other because it is not in the drop-down list.  This is because it is not in the same mobility group.   So my question is how do customers of anchor across a local WLC in a group of mobility to a WLC anchor in another group of mobility?

    To me it seems not possible without major configuration changes.   I don't want to reconfigure / rebuild mobility groups.

    Thank you

    Chuck

    Not only is it possible, that I recommend. However, you can be confusing to some concepts.

    The mobility group is different from that of the field of mobility.  Generally, I am referring to group mobility as these WLCs with the name of the default mobility group and the field of mobility than the entire list of mobility (where you can set up to 72 controllers belonging to various groups of mobility).

    The point is that GroupA and WLCs of to WLCs 1-10 11-20 are GroupB, anchor to work, you at least need to add anchor to the mobility list wlc abroad and vice versa.

    If you notice, when you add an entry of mobility to the list, it should ask you for mobility group. If you leave this field empty, it must default to that of the WLC, but on controllers GroupA, you could define GroupB controllers (and specific group b) and then you should now have the mobility between your controllers and configuration of the anchor will be your anchor in the menu...

  • The dual SSID Signal interference

    I have the cable and Internet provided by AT & T.  I mainly had Comcast when you live in different parts of the country.  I am owner of an Airport Extreme and Time Capsule I used previously to set up the network internal in addition to the SSID broadcast material of the cable company.  I never had a problem before using AT & T.  I noticed that the Internet speeds both the provider of cable and speed on the internal network have been seriously degraded.  I was unable to stream movies.  After several attempts to solve the problems with AT & T and myself, I found the problem: it seems to be interference of signals between AT & T and Airport Extreme material each broadcasting separate SSID in very close to one another.  I got the Apple hardware, and the problem was solved immediately.  While I'm happy to have it fixed, I don't miss the advantage of having the internal network using Apple devices.  What are my options?  Is it correct that I can't use the Apple devices to extend the SSID signal emissions equipment AT & T?  I think the problem might be solved, perhaps, if the two gateways were not close to one another, but I do not have another spot to plug the Airport Extreme.

    Is it correct that I can't use the Apple devices to extend the SSID signal emissions equipment AT & T?

    Unfortunately correct.

    Apple routers work that to extend another router from Apple... no other brand is invited to the party.

    I think the problem might be solved, perhaps, if the two gateways were not close to one another, but I do not have another spot to plug the Airport Extreme.

    Separate the two routers as much as you can... I always recommend 6feet or about 2 M. If they are closer than this really a wireless should be turned off. Only for this case deactivate the ATT router instead of your apple.

    There are enough wireless channels to run 3 wireless routers close to each other.

    Sometimes the automatic separation of channels does not work and you need to get and change physically.

    Use wireless diagnostics (many versions available, but it is built into Mac OS since the Mountain Lion)

    There are a bunch of tools... the actual diagnosis is not particularly useful in my experience.

    Open scan.

    You will need to click on it to see the whole thing.

    Now, I have a few questions... first, I'm not showing noise... This is just my configuration problem. But you should see RSSI (signal level), noise, channel, band, width and country.

    Watch channels... My installation has some problems because most of the 2.4 ghz is using channel 11.

    The diagnosis tells you even what channels to use.

    I can open airport utility and select one of the units in issue. Click the icon from the airport... Click on edit in the preview.

    Go to the wireless tab.

    Click Wireless options

    Change the automatic 2.4 ghz regardless of the channel you want.

    Save and update from the airport.

    Especially for 5 GHz, I think that your stay on auto should be fine. It is more short-range and isn't usually a big problem.

    Note also the signal strength really counts... things go wrong if you don't have enough separation and the signal strength is low.

    2.4 GHz, there are only 3 channels Alcan... 1, 6, 11

    Although Diagnostics of scanning you will offer between channels... do not be fooled that this corrects the problem.

    Read the wiki for wireless lan.

    https://en.Wikipedia.org/wiki/List_of_WLAN_channels

    Channel 6 for example is actually peak signal to 6, but it covers 4 to 8.

  • WiFi does not connect if the SSID is not broadcast.

    I've updated to Sierra this afternoon. Everything seemed fine after the update. After dinner, my MacBook Pro (retina, 15 inches, beginning 2013) would not connect to Wifi. I reduced to a few things.

    It wouldn't connect the 5 GHz n If the SSID has been hidden. If I admitted the SSID to shown, it would connect without problems. It would connect to the 2 GHz band, even with the hidden SSID.

    I did the typical SMC reset and reset the NVRAM. I deleted the files related wifi and restarted the router and the MBP. I'm obviously on now and the speed seems normal with no dropouts. I can't hide the SSID now and will continue to work until he's asleep; No dice after that without reactivation SSID broadcast.

  • Two extremes of the airport with different SSID

    I want to connect a garage to the rest of the House. (The garage becomes a living space). The main unit is an Airport Extreme. Could I connect another AirPort Extreme by hand via a power adapter carrier online - and set up mode bridge using different SSID as the main? I don't want to extend the network, etc. - people in the main House should never connect to the garage network. We just want to share an internet connection.

    Note: the machine takes care of everything - the modem is set to Transparent bridging mode, if that makes a difference. And we already have the extra AirPort Extreme. Thank you!

  • Problem of airtime with the same SSID

    I often use AirPlay to my iPhone and iTunes on my PC to play for my (home theater installation) AVR - 1506 Marantz.

    Configuring wifi in our House are a router/modem to the ISP and an Asus RT-N56U (in access point mode) with DIFFERENT SSID to which I don't have problem to play AirPlay on any device. I had the same SSID when so I can use wifi roaming without having to change the SSID whenever the other signal weakens.

    When I put two (router & AP) with the same SSID, Airplay icon will not be displayed? But if I put a different SSID to one of the two, airplay icon is back. Channels are on ch.1 (router) and ch.11 (AP). Someone knows how to set up?

    UPDATE:

    Disable NAT in fact access point the AirPlay icon always appear but he cannot yet play through my APR.

  • Safari freezes on link with anchor

    Hello

    https://translate.Twitter.com/Forum/forums/English-UK/topics/7000?page=5#post-54 600

    Note that this link has a #anchor at the end. When I try to open it with my mini iPad Safari browser (iOS 8) it causes app to freeze and when reopened, it freezes again if you try to do something. At the opening of the story, it is empty; When you try to type in a URL, the entry does not work.

    It's really annoying and I'm trying to avoid, but if I accidentally type one, I have to delete ALL data, cookies, etc., which is the worst because you have to connect to all your Web sites over and over again.

    Apparently some people have had this problem with Desktop Google Chrome too, so it's definitely a problem of coding the site.

    This happened to you too? What can I do to fix the freeze without deleting anything? I have tried the lock + home force shutdown, but it does nothing. Do you know where I can ask someone to examine what is causing the anchor all plant? I'm not a computer or coding knowledge, so if you understand how it works I got appreaciate if you look in this.

    Thank you!

    'Works for me.' You are using Safari on iOS 9.3.2. You say that you did a restart, but it does nothing. Do you mean it does not restart, or it does not help? Looks like it is a problem with your iPad, and not on the site.

    You have a reason to not update to the current iOS?

    I feel like this is one these questions silly, but for the life of me I can't find the answer.
