Flex Connect Across Multiple VLANS same SSID

I just need to find that if we have flex connect setup for differnet vlans using single controller, will roaming works when client connects to AP in a differnet VLAN but using same SSID.
Example below:
1) Client connects to AP on specific SSID mapped to VLAN 100, get an IP address ..all good at this point
2) Client walks and connects to a differnet AP on same SSID but mapped to VLAN 200...at this point I observe client doesnt get a new IP address in fact it retain IP from step-1 and there is no connectivity
3) Client walks back to first AP and connectivity is restored
Why in step-2 client doesnt gets a new IP from VLAN 200 even when it shows connected to AP.

Just to add to Rasika.... L3 isn't supported....I just ran into this a few days ago.... clients should request another dhcp when roaming to another FlexConnect AP that is mapped to a different VLAN. The issue is, that some clients don't try to renew their dhcp address and gets stuck with the default 169.x.x.x. I see this with Apple devices in general and what we are going to do is get rid of the multiple vlan setup (vlan per floor) and create a bigger vlan that the SSID will be mapped to.
Thanks,
Scott

Multiple Vlans Per SSID

Hi
We are just putting in a new Controller - 5500 type
We are using a WCS .
Someone has raised the issue of whether we can have multiple vlans
per SSID - as otherwise we may have very large broadcast domains
due to the overall design being to have Maybe 3 SSIDs
Guest
Staff
Engineering
I think in SWAN we could get away with dynamic vlans.
We would like to have multiple vlans in each SSID to avoid the above.
Can we do this in the new setup.
Kind Regards
Steve

Hi Steve,
yes it works just the same.
Enable AAA override on the controller and have interfaces configured for each vlan. Then the ACS can simply push the vlan depending on the user authentication. Users are then split in separate vlans.
Another way of doing is to group APs. You can have a group of APs serving SSID Guest in vlan 1, Employee in vlan 2 and another group of APs serving the same SSIDs but in vlan 3 and 4. It's "per-user" vlan load balancing or "geographic" vlan load balancing.
However, broadcast domains should not be a major concern in wireless as broadcasts are blocked by default. The WLC will proxy for ARP and DHCP.

Access Connections - Many APs with same SSID (Again)

I have a W520 running Access Connections 6.11 (release December 2013) on Windows 7 Pro 64-bit. Access Connections is still broken in regards to dealing with multiple Access Ponts having the same SSID. It keeps hoping from one access point to another regardless of signal strength of the AP.
The most desirable strategy would be if Access Connections would find and lock on to the best signal strength AP and stay there. However, it doesn't do that. It acts almost randomly. It also keep shifting around. The rate is almost random as well. Sometimes it will stay locked on to an AP for up to 10 minutes, at other times it shifts in as little as 30 seconds.
Other laptops, from other manufacturers like HP, Toshiba, and Apple do NOT exhibit this behavior on our campus. Other Lenovo machines running Access Connections DO exhibit this behavior. The problem is NOT machine specific (ie, not hardware or some weird idiosyncracy of the particular W520 i'm posting about). The problem is Lenovo's Access Connections. The problem is also not a configuration issue with the campus. I have a network at home running Airport Extremes all having the same SSID's and the W520 in question does exactly the same behavior there. Totally different hardware at home vs campus and same behavior. I cannot change the names of the AP as a fix. This is not a capability in the configuration of the AP's. Even if it were, I shouldn't have to do it. Campuses are often configured in this way. Campuses that are large commercial users who I believe are the most lucrative Lenovo customers.
This problem has been going on for literally years with different versions of Access Connections. Here are two threads in the Lenovo Community I found in under 30 seconds. Neither was solved correctly. In other words, Lenovo never fixed the software, and people had to either give up or resort to kludge solutions in their campus configurations.

Lenovo has actually made the problem progressively worse over time instead of fixing it. They have done this by removing the abilty to prioritize AP's by MAC address. Initially, Lenovo allowed you to configure 5 MAC addresses in order. Then, Lenovo removed that capability making it possible to only give a single MAC address as preferred. Finally, in recent iterations, Lenovo removed that capability alltogether. The box is still there in the UI, but it's greyed out. It is very frustrating to have this kind of thing happen. The prioritize capability is fundamentally a kludge, but at least it's something to give a bit of a workaround. Now we don't even have that.
Can a lenovo engineer please look at this issue and give me a timeline for resolution?
BTW, It is still not possible to configure Access Connections with a blank SSID either. I bring this up, because if you're going to fix the Access Connections code for multiple SSID's, you should be aware of the blank SSID problem as well. I imagine they are both in the same part of the Access Connections codebase, at least from a logical standpoint.
Thank you.

I found that there is a setting in the Intel driver (15.9.1.2, released 8/22/2013) for the wireless card (Centrino Advanced-N 6205). The setting adjusts the "roaming aggressiveness". I can only guess this means how often the driver goes out and tries to find a "better" signal and/or bandwidth. The card supports a/b/g so the calculus is complex as to what constitutes "better", and I have no idea how sophisticated the algorithm the driver uses is.
That said, if I set the "aggressiveness" to the most aggressive setting, things work somewhat better. They are still not as a good as other wifi managers bundled with competing products (specifically HP, Toshiba, and Apple so far), but it helps. It does appear that more of the time now, the AP having the best signal appears to be the AP the laptop is attached to.
Lenovo, please consider that forcing your customers to dig around in arcane driver settings and relying on the whims of driver writers and hardware companies to do things correctly and well, is a recipe for failure. Your customers are just going to get annoyed and say to their colleagues, "My old Toshiba seemed to do a better job of WiFi connections. I think next time, I'm going to have IT get me one of those again." And, of course, that colleague will look a lot harder at buying the Toshiba instead of the Lenovo, as well. Wifi connectivity is a very big deal for people who have to move around - and lets not forget, this is a laptop we're talking about, which is explicitly designed to, well, be moved around.
I apologize for being so pedantic, but it often takes such measures to get managers in these companies who control programmer time, to take these issues seriously and allocate the programmer resources to fix these problems.
The problem I am having is still not considered "fixed." I would very much like to hear any other solutions that work better. I would love to hear from Lenovo on the matter. Still waiting.
Thanks.

SUN NIS Broadcast across multiple vlans

We're big sun servers and clients shop. The problem is that NIS is not able to go across multiple vlans on a layer 3 switch. I have enable the forward-udp protcol sunrpc but it still doesn't work. Is anybody else ever run into this issue?

This might help you. Use the Ip-helper adress along with the forward udp command. Look at this link under the IP- helper command. Should answer your question.

Multiple VLANs per SSID with local switch

Is it possible to use an 'AP Group' or 'Interface group' to assign multiple VLANs to a WLAN when remote, h-reap APs are in local switch mode?
If not, is there a way to overcome 500 maximum host per VLAN when APs are local switching?
Thanks!

dont think its possible...
I donno if the following config will even work but u can have the hreap APs connected at the remote site to map to different vlans...
Example:
AP1 -- ssid 1 --- vlan 10
AP2 -- said 1 --- vlan 11 and so forth..
Sounds crazy but i ll have to ponder on this a bit more.. Need a pen and paper to draw a quick topology :)...

DHCP Setup across multiple VLANs on RV325 - DHCP Server only working on VLAN 1

I have multiple VLAN subnets defined on my RV325 - when I try and utilize a DHCP Server on each VLAN, it only seems to be issuing IP Addresses to clients on VLAN ID 1. When I first set this up months ago, I thought I had tested it providing IP Addresses via the other subnets. Now that I am trying to do so, it isn't working "as expected". Example - I am using VLAN 25 as the GuestWireless subnet utilizing a separate 802.11n WAP that is set to Bridge connections to the IP Address of the VLAN interface. Devices are able to connect to the WAP, but end up with a self-assigned IP Address 169.x.x.x address. There has to be an easy fix to this, but I seem to be "stuck" figuring out what it is…pointers/redirects appreciated. Thanks!

Thanks - I've already reviewed that information before I posted. I've been working with DHCP since the mid-90's, so I'm comfortable with the settings/configuration I need to leverage to make this work via other means using various Network-based OSes.
I'm wondering if there are other options in configuring this device that can impact the ability to dynamically serve IP addresses on a VLAN/subnet-by-VLAN/subnet basis.
As I did more testing, I discovered when I reserved an IP Address via the IP & MAC Binding option within the DHCP Settings, those devices would receive their static reservations and work as expected, so the problem seems to be leveraging the DHCP Pool for devices connecting to VLANs other that VLAN 1.
Any ideas as to why the DHCP Pool's are "non-functioning" for the other VLANs is greatly appreciated...
Each VLAN is setup with a separate DHCP Server configuration as shown below:
VLAN ID = 1 (Default, Inter VLAN Routing = Enabled, LAN1-6 = Untagged, LAN7=Tagged, LAN8=Excluded, LAN9-14 Untagged)

AP groups with same vlans , same ssid but different subnet.

Hi Members,
I have a Cisco Flex 7500 in my datacenter and I need to connect 100 sites , each site with 2-3 APs , each side has its own network and is independent of other sites , the site only need to comunity locally and do not need to access any centralized applications.
I am trying to achieve this by Creating 100 different AP groups and assiging 2-3 AP in each groups for each branch, I will achieve WAN failover resiliency by creating flexconnect groug , the issue I am facing are as below .
1.Since all the sites has same setup , the AP and clients on all sites are in vlan 2 , so when I try to create 2 or more AP group with same vlan, it restricts me of doing so , I cannot create diffrent AP groups mapped to same Vlan .
2.If I keep the APs and Clients in the same subnet , I dont think it should be a problem , but I need your second opinion.
to give you an even better picture , look at the topology enclosed , and my question is if both STAFF and STUDENT APs are in same vlan but in 2 different broadcast domain , how would I create the AP groups.
Thank you

Thanks for the reply Jenn , here is my situation.
I have 2 sites lets day , site A in virginia , site B in Maryland.
SiteA - 10.1.1.0/24 - vlan 2
           10.1.2.0/24 - vlan 3
           10.1.3.0/30 - WAN to central site where controller sits.
SiteB - 10.2.1.0/24 - vlan 2
           10.2.2.0/24 - vlan 3
           10.2.3.0/30 - WAN to central site where controller sits.
both the sites will have a single ssid "XYZ" and will switch locally only.
howin my understanding the way I will deploy this is as below
1.I will create WLAN with ssid "XYZ".
2.I will create 2 AP groups lets say "Site-A" and "Site-B"
3.I will map the APs in site A to AP group "Site-A" and APs in Site B to "Site-B"
4.I will create 2 dynamic interfaces one for each AP group , now this is where I am facing problem , when I am creating dynamin interfaces , I need to specify the subnet and vlans when creating dynamic interfaces , since the vlans used is same on both sites , its not letting me create 2 interfaces with same vlan id.
in my understanding HREAP is only majorly used for WAN failover and local authentication so I am not concerned about that right not , my prime work is to udnerstand the AP group and working.
if you still need print shot let me know I will have to go at site.
also validate if my thinking is right on the 4 steps I have mentioned above , I am new to wireless and whatever I have learned I have learned in last 10 days .
Appreciate your help.
Thank you

How do I get my ARD/AppleTV to work through bonjour across multiple vlans?

I am having a heck of a time, I have 200 iMacs running 10.9 and a 10.9 server. We also have 30 apple TVs. These are spread over 5 distinct vlans and I am having a heck of a time getting them all to see each other. I found some information that started getting over my head about adding a bunch of dns entries for each device which would not scale well, and all seemed to be for printers anyways so I have turned here for some hopeful assistance.

Bonjour is designed to stay on the local LAN and not go across routers, with VLANs you have split your network up and Bonjour normally will not cross the splits even if you enable TCP/IP routing between VLANs.
There are various schemes aimed more for site-to-site situations to force Bonjour across links but in your case you might want to look at some newer devices specifically made to 'manage' Bonjour traffic.
Note: Bonjour is the same thing as mDNS i.e. multicast DNS.

Apple's AirPort Extreme can also do 'Wide Area' Bonjour between two or more sites but I don't feel it is suited to your case.

Need help configuring multiple VLANs and SSIDs

Hi,
We bought a Cisco SGE2000P 24Port switch and 10 WAP4410N access points. Our intent is to provide a secure network to our LAN, and a guest network to the Internet.
We are thinking 3 VLANs would be best for this: VLAN 100 connected to the LAN, VLAN 1000 for the Internet Router and Filter, and VLAN 1100 for the Guest Wireless access.
We have the switch configured for all three of these, and 1 initial access point configured for the VLANS, too.
We have not yet moved the current Internet connection to VLAN 1000 because we aren't sure how to setup routing between VLANS.
Here are some specifics on how the traffic needs to route:
1. We have the DHCP server, which is the PDC, handling both scopes for the LAN and Guest VLAN.
2. The web filter in VLAN 1100 needs to authenticate with the DHCP server as there are different filter rules based on authenticated user. Any users coming from VLAN 1100 will have a default filter rule without requiring any authentication.
3. Certain traffic coming in from the Internet needs to be able to get to VLAN 100. The router has a built-in firewall that handles NAT and port forwarding, so as long as traffic can be forwarded to VLAN 100 we should be good.
4. Traffic on VLAN 1100 (guest Wireless network) should only be allowed to go to Internet (VLAN 1000).
Right now I have the VLANs configured and the ports assigned to the Access Points are set for TAGGED and on VLAN 100 and VLAN 1100.
The SGE2000P has the following IP addresses assigned to the VLANS:
10.7.3.252 - VLAN 100
10.7.40.254 - VLAN 1000
192.168.254.254 - VLAN 1100
Has anyone been able to setup a similar configuration? We have scoured the Internet for documentation but it seems to be very difficult to find!
Thank you!

Based on your description of a 'Hybrid Port' this sounds like Cisco's 'Multi-VLAN Port' that was a feature of the 2900XL/3500XL series switches. This feature has however long since gone......
With a Cisco switch an access port supporting an Access VLAN & a Voice VLAN is effectively a Trunk with only one Tagged VLAN and the Native VLAN:
interface FastEthernet0/1
switchport mode access
switchport access vlan 10
switchport voice vlan 100
This results in the same configuration as:
interface FastEthernet0/1
switchport mode trunk
switchport trunk encapsulation dot1q
switchport trunk native vlan 10
switchport trunk allowed vlan 100
With the exception of CDP packets being sent advertising the Voice VLAN.
With regards to other IP Phone vendors and DHCP Vendor Options - the answer is it depends....
Nortel use Vendor Option 144 to inform the IP Phone of the Voice VLAN and Option 128 for the Server (PBX) to use. Ericsson uses Vendor Option 43 that can be configured to tell the IP Phone the VLAN and the Web server to read the config file from.
I don't think you will get this working automatically with your 3Com switches, you can however manually configure the VLAN on the Cisco IP Phones.

Share photos across multiple accounts same machine--issues

Dear All,
I recently created a disk image as per the following article: http://support.apple.com/kb/HT1198?viewlocale=en_US&locale=en_US, section
Alternatively, move the iPhoto library to a disk image
Subsequently I copied the iphoto library to this disk.
Now when I connect with one user, I see all the pictures OK, no problem. I log out (or even restart the computer) and connect with a different user (yes, I made sure the permissions are set read/write for these two users). With this new user, every time I open the library from that shared drive I get an error (something about the library is locked asking me to restart the computer); when I do I get the same. Then I open iPhoto with "option"+"command" and choose rebuild database (after tryiong repair unsusccessfully). The stupid thing keeps munching and munching for hours at in (library has 80 GB) and in the end it screws up all my events and put pictures (not sure they are ALL there) in a stupid event called "recovered photos".
I have tried everything I could, I don't know what to do anymore. Please help (yes, I ran disk utility verify disk and verify permissions, all seems to be just fine).
THANKS!

The message that I get when trying to open the library from the other user account is:
Your photo library is either in use by another application or has become unreadable
Shut down and restart your computer, and then open iPhoto again. If the problem persists, try rebuilding your photo library. To do this, quit iPhoto, and then reopen it while keeping the Option and Command keys pressed. You can also try restoring your photo library from a backup.

WRT610N - connected to multiple networks?

Hi all, I bought and set up one of these routers yesterday and initially my laptop reported it was connected to multiple networks, same SSID but different antennae, it meant I could switch between 2.4 and 5.0 GHz without dropping connection and obviously had great connection strength. But after a shut down and restart it will now only connect to one antenna at a time. Which is the correct way for the connection to work, should it be connected to only one antenna at a time?
Thanks in advance.

I've obviously not been clear, when I set up the router yesterday I set different SSIDs for the two bands, LINKSYS1 for 5GHz and LINKSYS2 for 2.4GHz. When I connected to LINKSYS1 I got 2 connections simultaneously, one labelled "LINKSYS1" and another lablled "LINKSYS1 2" both providing a 5GHz connection. I also had another connection at one point called "LINKSYS1 3". Exact same thing happened when I connected to the 2.4GHz band "LINKSYS2" (i.e. I had 2 connections labelled "LINKSYS2" and "LINKSYS2 2" both providing a 2.4GHz connection). Hovering over the network icon showed 2 connections and network and sharing center showed connected to multiple networks. When I restarted it this morning it's only connecting to one and the converage isn't as good (could get 100% signal from outside last night and stream DVD iso's but it's buffering quite a bit today). I've googled it and some other people have mentioned the same thing but they seemed to think it was a fault, but it gave me better coverage than I'm getting today. What I was asking was which is the correct way for it to operate, as one connection or multiple connections.

Single Corporate SSID + Single Guest SSID across 200 sites over VPN with Flex Connect

We have two main sites (East Building as DR + West Building as BDR) + 100 remote sites / all connection between the sites based on VPN / OSPF
East building has 1 WLC 5508 with a license of 500 AP
West building has 1 WLC 5508 with a license of 500 AP
50 remote sites in East
Each East remote site have 5 AP (AIR-LAP1142N + AIR-CAP2602I)
Total AP in all the 50 remote site in East is 250 AP
50 remote site in West
Each West remote site have 5 AP (AIR-LAP1142N + AIR-CAP2602I)
Total AP in all the 50 remote site in West is 250 AP
Hardware available are:
2 * WLC 5508
2 * ACS 5.2
Most of the switches that connect to the AP are 2960G
All the AP are
AIR-LAP1142N-E-K9
AIR-CAP2602I-E-K9
Requirements in Brief:-
1 SSID for Internal user across all the sites
1 SSID for Guest user across all the sites
All IP for all the sites based on their local subnet
All the remote sites need to be Flex connect
The 2 WLC need to configure as failover
Requirements in Details:-
One Corporate ABC-SSID for all the sites
One Guest ABC-SSID for all the sites
The WLC in East building is the primary which control all the East remote site (250 AP)
The WLC in West building is the secondary which control all the West remote site (250 AP)
A fail over between the two WLC as below:
If the WLC in east fail then all the AP in east (250 AP) will connect to WLC in West
If the WLC in West fail then all the AP in west (250 AP) will connect to WLC in East
Each Remote site behaving as Flex connect to reduce the overhead over the WAN/VPN
Each site must have their own AP groups for the ease of management
All the AP MGMT IP based on their local subnet
Each remote site, West building, and East building must obtain their IP based on their local VLAN Example:- site-1 in East:
Corporate ABC-SSID take 10.204.0.0/24
Guest ABC-SSID take 192.168.0.0/24
Example:- site-2 in East:
Corporate ABC-SSID take 10.204.1.0/24
Guest ABC-SSID take 192.168.1.0/24
Example:- site-3 in East:
Corporate ABC-SSID take 10.204.2/24
Guest ABC-SSID take 192.168.2.0/24
And so on…….
Example:- site-1 in West:
Corporate ABC-SSID take 10.204.100.0/24
Guest ABC-SSID take 192.168.100.0/24
Example:- site-2 in West:
Corporate ABC-SSID take 10.204.101.0/24
Guest ABC-SSID take 192.168.101.0/24
Example:- site-3 in West:
Corporate ABC-SSID take 10.204.102.0/24
Guest ABC-SSID take 192.168.102.0/24
And so on…….

Expert I'm really stuck here, so please any help will do.
Thanks in advance

What are you stuck on? What you have mentioned is possible.
When you setup FlexConnect and also when AP's night failover, you need to make sure that the WLAN ID are in the same order in bother WLC's. also the AP Groups have the same information and have the same AP Group names and WLAN to vlan mapping. So as long as the WLC's are configured exactly the same except for IP addresses and hostname a, failover for FlexConnect will work fine.
Now the FlexConnect WLAN to vlan mapping is done on the access point itself. So each AP will have to configured. AP Groups will not help here as you can really just create one since you will have the same WLAN's broadcasting at each site. You can make is simple though:) and this is a good tip.....
If all your vlans are the same in every site including your DR and BDR, then the WLAN to vlan mapping will use the vlan if you have specified in the the WLAN under the I terrace mapping. So if in your corporate WLAN it is mapped to I terrace vlan 100, all you FlexConnect AP's will have that mapping set to vlan 100. If your guest at WLAN is mapped to vlan 999 interface on the WLC then the FlexConnect WLAN to vlan mapping for the guest will be set to vlan 999.
Now if you have different vlan id's for each site or it might be the same for some and not the others, well you will have to tough each AP and configure the WLAN to vlan mapping.
The WLAN to vlan mapping appears only when you have enabled FlexConnect local swit hung in the WLAN and you have the access point in FlexConnect mode.

Multiple Cisco Aironet 1131AG access points and same SSID?

We have multiple Cisco Aironet 1131AG devices, all wired on one Cisco L2 switch(2560) who is connected to L3 switch (3550). We assigned one VLAN for access point in L3 switch who acts as vtp server (L2 switch is vtp client). All ap's will have static ip address and all will have same SSID and no security and they will be using multiple channels (ex. 1,6,11). They will operate in 3 floor building for roaming wireless client. We won't using any wireless controller.
So my question is this: How to configure APs-all the same with different ip's, can we use L3 switch to create dhcp server for access points VLAN (pool for clients, and the rest for static ip for ap's)? Can one of the ap's be WDS and in the same time local radius server with users without Cisco Secure ACS or similar controller or I didn't understand this quite well :-). I followed guide http://www.cisco.com/en/US/docs/wireless/access_point/12.3_2_JA/configuration/guide/s32roamg.html for WDS where the part abou Cisco ACS is a problem, so I can use same ap as Local Authenticator as in guide http://www.cisco.com/en/US/docs/wireless/access_point/12.3_4_JA/configuration/guide/s34local.html#wp1035723.
Many thanks...

Well, just so you know, WDS and local RADIUS authentication is only needed if you're using authentication on your wireless connection. You say you're not planning to use security, so this isn't necessary. However, I'd highly recommend at least using a simple WPA2-PSK to lock down your connection, otherwise you might end up giving free Internet access at best, and at worst you might be giving access to company PCs and servers. If you want to further use an 802.1x or WPA authentication method, then yes, you can use an AP as a RADIUS server and WDS to improve authenticated roaming, but this is far more limited than using a Cisco ACS.
As for your other questions, yes, your APs can all be configured the same except for at least three parameters: IP address, channel, and hostname. Configure your static IP addresses on the AP's BVI1 interface. Don't place it on the Radio or Ethernet interfaces, because if either of these interfaces goes down you'll lose the ability to configure the AP, so it's best to use the BVI1 interface.
And yes, configuring a DHCP scope for your clients on your L3 switch is a good design, or you could also use your DHCP server on a different subnet by using the ip helper-address command on the L3 interface. I hope this helps! Let me know if you need help configuring any of this.
Merry Christmas!

Multiple OLE DB connection managers to the same database instance in a SSIS package

Hi,
While migrating DTS package to SSIS package, I came across one which had multiple OLE DB connection managers all connecting to the same Oracle schema in the same instance.
There are that many execute SQL task corresponding to each of these connection managers.
Each of these SQL task call different Oracle stored procedures and executes them in the same schema in the same instance.
My question is, is there any particular reason or advantage in having multiple connection managers?
Can't we have one single connection manager and use the same in all of these SQL tasks?
Does multiple connection managers provide any added advantage like parallelism or something?
In this particular case, there are no actual workflows, rather each of these SQL tasks are stand alones. But there are other packages which has SQL tasks in workflow but still each of them calling separate connection managers all calling the same schema
in the same instance.
Thanks for your time.
Cordially, Biju George

Well like I said, each of these SQL task calls "different" Oracle stored procedures even though executes them in the same schema in the same instance. I tried a sample testing by creating two separate packages, one with only one single
OLE DB connection referred in all of the SQL tasks and in the other one with mutiple OLE DB connections to the same schema in the same instance each of which is referred in each of the SQL task in one to one mapping.
Now the first one created one session in Oracle but the later created as many sessions as there where OLE DB connection managers. The first one took longer to complete than the second one since second one created independent sessions and executed those procedures
sort of parallely.
I guess that can be called an advantage of creating multiple connection managers to the same schema in the same instance.
