Requirements for VLAN select feature in 5508 WLC

Hello,
We implemented WLC 5508 software version 7.3, with 8 Aironet devices, most of them are AIR-LAP1131AG-E-K9, and two AIR-LAP1242AG-E-K9.
I could really have benefits of VLAN select feature, but I noticed that it's not working like it should. Two interfaces are in Interface group, but from 45 clients only few of them has IP address from one subnet, others have from second sub.
I see requirements for this to work is 32 MB of flash on LWAP devices..I only have 16 MB..
Is there a way to work this thing out? upgrade of flash on devices or something ?
Thank you in advance and kind regards..
Lovro

Thx L - as usual, I need to read before speaking
Interesting topic though. I would assume that the MAC hashing algorithm used would be similar to how etherchannel maintaines load balancing (src-dst) etc.. What I don't quite understand is the definition of "dirty". What makes an interface "dirty"? Given the flow chart depicted in the link you sent, I'm wondering how the interface assignments are kept in te switch. I'm assuming you create the interfaces, create the interface group, assign the interfaces to the group and finally assign the interface group to the WLAN. During all this time, how are the stations using that WLAN being handled? Almost should clear everything out, create the group tied to the wlan, THEN join the stations one at a time and see what interface they get assigned to. At that point it should be balanced. Also, it's my understanding that those stations should keep their assigned interface the next time they connect unless there is a "dirty" condition which I don't quite understand yet.
Anyway - rambling now. Loking forward to your test results. Thx again! //art

Query on administration tasks required for enabling flashback feature

Hi All,
I would like to enable FLASHBACK on 4 tables in a schema.
I know that the RETENTION GUARANTEE clause needs to be set on the UNDO TABLESPACE. But as flashback is required only on few tables, setting RETENTION GUARANTEE will cause a lot of pressure on the tablespace in terms of space.
Can anyone suggest a solution for this?
Thanks in advance,
Annie

Audit information will appear in the 'Output' panel in the Test View and the Query Plan View after executing if the application is Audit enabled and the audit 'Severity (threshhold) Level' is set such that audit events are generated. (i.e. if you have the Severity Level set to Failure, then audit events will not be generated for events that specify 'Info')
There is no 'Audit Console' for DSP.

WLC 5508, vlan select, reserved address in external DHCP server

Hi guys,
I have a deploy with a WLC 5508 version 7.0.116.0, APs mode local and vlan select feature enable. The issue is that the reserved IP address in external DHCP server not work. The DHCP contains a reserved IP address associates with mac address, but the assignement of IP is not match with de policies in DHCP. All others services operate normally.
This reserved assignment operate previusly to modificate the WLAN to vlan select feature. Help me to improve this situation.
Thanks.-
Best regards

Hello Abhishek, thanks for you quick answer....
the link was a document used for the deploy, but not especifict nothing about the reserved IP address for particular host. In other words, the reserved IP address (through MAC address) in external DHCP server not work when "vlan select" its enable.

Vlan Select & Layer 2 Multicast optimization

I am going to implement this vlan select feature in my campus network. We are running on 7.3 & planning to move into 7.4 WLC code as well. I use below reference document for this task.
WLC 7.2 VLAN Select and Multicast Optimization Features Deployment Guide
I am bit confuse about layer 2 multicast optimization. Document says we can enable/disable by using below CLI commands. "
config network multicast l2mcast <enable|disable > <interface>"
I have 4 interfaces called student-wireless-1 to 4 (vlan 1161-1164) map into single interface group. For layer 3 multicast I will make vlan 1161 as the multicast interface with "multicast vlan feature" enabled. For layer 2 what should I do ? Is layer 2 multicast enable on all these interfaces by default ? If so should I disable l2 multicast on 3 of these interfaces like below ? Would there be any issue of disabling this layer 2 multicast on those interfaces ?
config network multicast l2mcast disable student-wireless-2
config network multicast l2mcast disable student-wireless-3
config network multicast l2mcast disable student-wireless-4
If it is not enabled by default, shoud I go ahead enable it on one interface like below ?
config network multicast l2mcast enable student-wireless-1
If someone can explain this that would be highly appreciated.

Thanks for the help but I found some further information. Some switches (2955, 2960, 3560 or 3750) can act as a "multicast querier", taking place of a multicast router without actually needing to support multicast routing. This means you dont actually need IP Services IOS or a layer 3 switch.
Configuation as per below;
http://www.cisco.com/en/US/customer/products/hw/switches/ps5528/products_configuration_guide_chapter09186a00803a9a29.html#wp1187873
Supported platforms below (look for igmp querier);

Thanks for putting me on the right track however.

VLAN Select - Interface dirty - Index based on Mac Address

Hello Experts,
we are testing the VLAN Select Feature with a 5508 controller, version 7.0.230 and two /23 DHCP Scopes on an external dhcp server. Our cookbook is following document:
http://www.cisco.com/en/US/products/ps10315/products_tech_note09186a0080bb4900.shtml
Now i have a few questions
1 - Is there any chance to see the calculated index based on the Mac Address to which the interface is assigned to the client. I try "debug client MAC-ADDRESS" and "debug dhcp", Maybe i overlook it, but i can't find any information to that index.
2 - Is there a cli command to delete the index? It would be great for testing purposes and troubleshooting.
3 - Is there a cli command to look, if the interface is "dirty"?
4 - Our DHCP Server has a lease time of 5 Minutes. Is it possible to set the interface dirty time to a value less than 30 minutes?
Best Regards,
Michael

I know this is an old post - but I ran across it trying to find an answer to the same questions.
Did you ever find any answers? I did find an answer to question 3, show interface group detailed.
But I haven't found a way to delete the indexes short of rebooting all the controllers, and apparently you would have to reboot them all at the same time.

Radius NAC VLAN select support

Hi all,
I have digged through the WLC documentation for 7.3 and in the chapter about Radius NAC I read that the VLAN select feature is not supported.
Does anyone know if this will change?
VLAN select is actually a useful feature and I wouldn't understand if NAC support over the ISE won't be possible.
Hope someone can shed some light on this.
Regards,
Patrick

I think with radius the vlan select and dynamic vlan assignment are two different topics. You can have ISE set users on different vlans within the same WLAN as long as the interface is present on the controller. I have tested this and works just fine.
The vlan select maybe a topic that the wireless folks can shed some light on.
Thanks

5508 WLC in HA over a L2-VLAN

Hi everbody,
I am very interested in the new 7.3 feature HA.
Also I can read that it is recommended to connect the two WLCs directly.
Has anyone tried to use a L2-VLAN between them, in fact to bridge a distance between two data centres?
Thank you for your answers.
Regards
Stephen

Hello,
As per my understanding direct connectivity of Redundant Port is required for HA.
for more details you can visit the below link:

Requirement for Native VLAN on Flexconnect Access Point

Hi All,
Just looking at AP configuration using 5508 WLC.
We have APs deployed at all branch sites connected over a corporate L3 WAN to a Data Centre which houses the WLC(s)
When setting the AP for Flexconnect mode there is a requirement that one native VLAN must be configured for each FlexConnect AP. If the AP is attached to a L2 switch and I want to enable multiple VLAN Mappings then I would need to add these VLANs to the allowed VLAN list on a trunk link between the AP and the switch (802.1Q) on the branch site.
Normally if I configured a trunk link I would never add the Native VLAN to the trunk and never use it for any traffic. In this case it would appear that I MUST use the native VLAN (which seems to go against my better judgement). So my question (after all this) is: What must the AP use the Native VLAN?
Thanks All.

This has always been a standard practice for access points that has to connect to a trunk port. This goes back to the autonomous access points and also with FlexConnect and Mesh if your setting up Ethernet bridging. Wired side is different from the wireless side as you have noticed.

User exit/BADI required for coding for the selection custom fields in RSA3

Hi,
I have a requirement in the Datasource extractor. I need to add custom Z fields in the Data souce of the 2LIS_02_SCL and need to include in the selection part. So I have added the custom filed in the append structure and include the check in the selection checkbox in the transaction LBWE under the datasource specified above. For the corresponding custom fields, to be populated in the ALV list, I have written the code in corresponding user exit ZXRSAU01.
Now I can view my custom Z fields in the list as well as on the selection fileds while executing the transaction RSA3. But I need to write code for the selection criteria part. On entering value in the selection criteria of my custom z field, no values are selected to the corresponding query. Please let me know where should i write the coding part for the selection criteria of the Z fields for the Datasource.
On debugging, to my understanding only the standard fields are alone getting filtered by providnig the values in the selection part of the RSA3 tcode. It is called in Macros : Sel < Datasorce> .... and the fetch cursor is included inside the macros.
Please let me know any user exits or Badi;s available for it.
Thanks in advance

Hi shivu,
you might try the BAdI RSU5_SAPI_BADI. A good introduction can be found in the following document:
[Enhancing DataSources with BAdI RSU5_SAPI_BADI|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/3001894b-b1fb-2910-77ba-e80b6f2053b7]
The BAdI is called at the time of extraction, so this would be the right place to populate your additional fields.
Best,
Chris

Hi Sanjeev,
If you input any deptno and you should get all the empname corresponding then first you need to use CALL FUNCTION 'DYNP_VALUES_READ'.

declare: DATA : gt_dynp LIKE dynpread OCCURS 0.
loop at gt_dynp into wt_dynp where fieldname = 'P_SUPRID-LOW'.
lv_low = wt_dynp-fieldvalue.
endloop.
Then while selecting use this p_superid-low instead of p_deptno.
Then :
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
After this funtion module:
write:
IF sy-subrc = 0.
    READ TABLE itab

    'p_empnam' = return_tab-fieldval.
Declare return_tab as:

Cisco 5508-WLC using MS NPS as RADIUS Server for EAP-TLS

Has anyone experienced a problem getting a Cisco WLC to work with MS NPS server? We've done it before albeit with differnt code versions.
I have a Cisco 5508 WLC running 7.0.116.0 code hosting a WLAN configured for WPA2 with 802.1x for authentication. I have two Windows NPS servers configured as the RADIUS servers for EAP-TLS authentication. Via debug info on the WLC I can see the 802.1x handshake take place with the wireless client and the WLC as well as a successful transmission of an Authentication Packet from the WLC to one of the RADIUS servers. However on the WLC I see repeated RADIUS server x.x.x.x:1812 deactivated in global list and on the NPS server I'm seeing event log errors indicating "The Network Policy Server discarded the request for a user" along with the pertinent auth request info that I would expect the NPS server to receive from the WLC.
Based on the WLC debug info I'm never actually getting to the EAP-TLS certificate authentication part. It seems the NPS servers don't like the format of the initial RADIUS authentication request coming from the WLC and so don't respond whcih in turn casues to WLC to switch to the other NPS server which produces the same issue.
Any ideas of what might be the issue or misconfiguration?

Jim,
I wanted to know if you can setup wireshark on both of the boxes and see if your are hitting the following bug:
http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCti91044
It looks as if the WLC is retransmitting the client traffic from one radius session with primary over to the secondary in which the radius state attribute that was assigned from the primary server is probably hitting the secondary server. Therefore if the state attribute isnt assigned from the secondary server it will discard the packet.
May need to open a TAC case to see if this issue is on the 550x controllers also.
Thanks,
Tarik

Any parameter is required to set "select for Update"

Hi all,
For using "Select for Update" statement, is any parameter is required to set at the database level.
Thanks in advance,

Hi,
I did't get any problem. but before implementing that I searching for any overheads.
I had read that some transaction isolation level should be required to use "select for update".
I did't catch it clearly.
Can u explain briefly if you know/any body know.
