Cisco 1702i WAP: how to get an interface in a non-native bridge group/ VLAN to be recognized by the internal DHCP server
Does anyone know how the internal DHCP server in these access points connects to virtual interfaces and bridges in the unit?
Is there some sort of default connection that connects the DHCP server to the native bridge group or VLAN?
In a test case, with an SSID in the native VLAN and bridge group, the 1702i serves an IP address to a wireless client no problem. But with a second SSID in a non native VLAN and bridge group, no IP gets served. My only guess is that since the bvi1 defaults to the native bridge group and VLAN, sub-interfaces also in this group are assumed to be in the same subnet as bvi1, or in this case:
interface bvi1
ip address 192.168.1.205 255.255.255.0
no ip route-cache
exit
It would be the ..1. subnet.
Since the dhcp pool is set as:
ip dhcp pool GeneralWiFi
network 192.168.1.0 255.255.255.0
lease 1
default-router 192.168.1.1
dns-server 8.8.8.8
exit
There may be an assumption that anything bvi1 can talk to is in the ..1. subnet, so the above pool gets activated on a request coming through bvi1.
Is the DHCP server just hanging out waiting for a request from an "area" that is assumed to be on the same subnet as the given pool?
Do I need to somehow show the device what subnet the 2nd SSID/ subinterfaces are in so the internal DHCP server can decide it needs to go to work, or is there some sort of bridging between the DHCP server and the interfaces that needs to be done? I am trying to use the same DHCP pool for the second subnet at this point, since I assume I will need another router to service an additional subnet and DHCP pool.
Keep in mind that DHCP is a broadcast packet to start. So the AP can only listen in the subnet that it has an IP address for.
Now, for any other subnet you can use the AP for DHCP but you have to have an IP helper address on your L3 pointing back to the AP.
That being said, I wouldn't use the DHCP server on the AP as it is limited. You'd be better off using a Microsoft server or some other device that is designed for DHCP.

When I open a pdf file, after a few seconds, it hides the toolbar and I don't know how to get it back. I use multiple monitors and, without being able to grab the toolbar, I am unable to move the pdf file to a different monitor. How do I stop this?
Does Firefox switch to full screen if you press F11 ?
You can also try the F10 key to see if that brings up the menu bar.

It works, if I use another IP (aka DHCP server) in the same subnet or in another subnet. It works also for the management interface.

Has somebody an explanation for this issue?
Thanks in advance,
Regard,
RobertYou can use the internal dhcp, but you need to set the primary dhcp as the management ip. So in your dynamic interface, your primary dhcp is configure with the wlc management ip address. Dhcp proxy also needs to be enabled and is enabled by default.

Cisco PI 2.0 API - GET Device Interface Description
Hi,
we are using Cisco Prime Infrastructure 2.0 as our central device discovery and inventory for all network equipment. Then we export the database to multiple other systems, primary through the REST API. My question is if anyone have used the PI API to retrive a device interface descriptions?
Looking at the documentation at https://[prime IP]/webacs/api/v1/data/InventoryDetails?_docs you'll see under the value PhysicalPort[] a description field, but it seems like it only get the port name i.e. FastEthernet1/1. Basically the same as the Name field.
Do anyone know how to get the description on an interface through the Cisco PI 2.0 API?
Cheers // MattiasBecause you would think that GET InventoryDetails -> PhysicalPort -> Description would be it... but no, it shows exactly the same thing as "name"!?
PhysicalPort[]
physicalPort
This nested field provides information about the physical ports associated with this device.
Type

How to get selected row from a non-bind ADF table
Hi,
I have an ADF table that is based on a collectionModel built programmatically. The collectionModel is this:
model = new SortableModel(new ArrayList<ArrayList>());
Hence, it is not a binding table. My question is how to get the selectedRows from a non-bind table.
I am used to building binding ADF table and I know we can get it from voiterator.getCurrentRow, since the selectionListener is set to the binding....collectionModel.makeCurrent
<af:table value="#{bindings.ItasLookupTypesVO1.collectionModel}"
selectedRowKeys="#{bindings.ItasLookupTypesVO1.collectionModel.selectedRow}"
selectionListener="#{bindings.ItasLookupTypesVO1.collectionModel.makeCurrent}"
</af:table>
I am thinking maybe I need to write my own selectionListener, but need more advice/ideas of what's the codes in the customer selection Listener to get it from my SortableModel.
Please help.
Thanks
-MinaI'm not sure if this works in your case, but check out the selection listener I write in this blog http://wp.me/pcBZk-eu
You should use the selection event and check the added set. This should give you access to the selected row.

How to get list of approved MSU for specified target group
Hello guys,
I have question about WSUS on windows server 2008 r2 sp1.
I need to get list of approved MSU for specified target group only for windows server 2008 r2 sp1, but I don't know whole syntax.
I can get list of approved updates for w2k8r2sp1:
$Title_r2='R2'
$Itanium='Itanium'
$wsus.GetUpdates() | Select Title | Where {
$_.Title -match $Title_r2 -and $_.Title -notmatch $Itanium -and $_.IsApproved -eq 'True'
But how can I get it for specified target group?
Please, help :)But how can I get it for specified target group?
Is there some reason you're not just using the native console reporting to do this?
Testing for 'R2' in the title will not guarantee getting all of the applicable updates, you need to query by Product Category to get all of them.
From my quick research, it appears that GetUpdates() does not return target group information, just a flag state on whether the update has been approved, or not. I don't have a working PS WSUS instance available to me at the moment, but my guess would be
that GetUpdateApprovals() (or something like it) is what you'll need to use to filter by Target Group.

WLC 5760 with internal DHCP server, clients no get IP address
Hi all,
I have 2 Cisco 5760 WLC (active-standby) IOS-Xe 03.03.03SE with one WLAN.
sh wlan summary
Number of WLANs: 1
WLAN Profile Name SSID VLAN Status
1 Invitados_ADSL Guest 905 UP
sh vlan
VLAN Name Status Ports
1 default active Te1/0/3, Te1/0/4, Te1/0/5, Te1/0/6, Te2/0/3
Te2/0/4, Te2/0/5, Te2/0/6
100 VLAN0100 active Te1/0/1, Te2/0/1
101 Planta_1 active
905 Internet active Te1/0/2, Te2/0/2
The DHCP server is internal.
Sometimes the clients no get IP address and the DHCP pool has IP addresses available.
The workaround done by me to solve the issue is “clear ip dhcp binding *”.
Some days later the problem appears again.
I see this bug with a similar problem:
NGWC blocks DHCP traffic if wireless broadcast disabled
CSCun88928
Description
Symptom:
Some clients set the BROADCAST flag on the DHCP Discover packet. This requires the DHCP server to reply with a broadcast.
In that case and if you are not using DHCP snooping on the 5760/3850, then the controller will block the return traffic unless you enable "wireless broadcast" which enables broadcast globally (and is thus not always desirable)
Conditions:
Seen on 3.3.2 IOS-XE
Workaround:
Use DHCP snooping with the "ip dhcp snooping wireless bootp-broadcast command"
OR
Enable "wireless broadcast" globally
My DHCP configuration is:
ip dhcp relay information trust-all
ip dhcp snooping vlan 905
ip dhcp snooping
ip dhcp excluded-address 172.16.0.1 172.16.0.19
ip dhcp excluded-address 172.16.1.250 172.16.1.254
ip dhcp pool Invitados
network 172.16.0.0 255.255.254.0
default-router 172.16.0.1
dns-server 212.66.160.2 212.49.128.65
lease 0 8
I see in Cisco documentation (http://www.cisco.com/en/US/docs/wireless/technology/5760_deploy/CT5760_Centralized_Configuration_eg.html) this configuration:
DHCP Snooping and Trust Configuration on CT5760
ip dhcp snooping vlan 100, 200
ip dhcp snooping wireless bootp-broadcast enable
ip dhcp snooping
interface TenGigabitEthernet1/0/1
description Connection to Core Switch
switchport trunk allowed vlan 100, 200
switchport mode trunk
ip dhcp relay information trusted ip dhcp snooping trust
interface Vlan100
description Client Vlan
ip dhcp relay information trusted
My question is,Do I have to add the command "ip dhcp snooping wireless bootp-broadcast enable" to solve the issue?
Thanks in advance.
Regards.
DYes, test it with the command you mentioned
ip dhcp snooping wireless bootp-broadcast enable

tabs: previous versions of firefox allowed for saving all tabs with a group name, so you could open them all again later at your convenience. The new firefox 4.0.1 has a new tab feature, but the tab groups do not seem to persist once you shut down, and are not saved as a folder in your bookmarks. What am I missing? How can I do what I want (save permanent set of tabs as a group that is available later, like the folder of bookmarks was)? Thanks
Right click one of the tabs, the "Bookmark all tabs..." option.

How to get PTInternalSession interface in Aqualogic 5.x?
I am trying to use CreateCursor() method on Aqualogic 5.0.5 using Server Portal API for which I need the handle to Internal Session interface.
I have the handle of IPTSession interface which exposes a method Get__InternalSession(object Token) which returns IPTInternalSession instance. Unfortunately I am not able to get this method to work.
The code is like:
IPTSession _ptsession = PortalObjectsFactory.CreateSession();
_ptsession.Connect("Administrator","",null);
IPTInternalSession ptInternalSession = (IPTInternalSession)_ptsession.Get__InternalSession(_ptsession.GetToken(300));
ptInternalSession.CreateCursor(...);
I am getting an exception "Value does not fall within the expected range" when the third line above is executed.
Similar code for Aqualogic 6 however works fine though the interface has some changes. GetInternalSession function does not require any token and the implementation has been moved to InternalSession class.
Any help on this or an alternate method for running CreateCursor on AL 5x will be highly appreciated.Here's a list of "Rules" you can use in GlimmerBlocker to block those annoying in video adverts on "Vevo" and "Daily Motion"...

How to get GH4 RAW files to work natively in Lightroom 4.4
I want to know how i can process Panasonic Lumix GH4 RAW files within Lightroom 4.4 like i use to do with my GH3. I have updated camera raw to 8.6 so i can use Photoshop CS6 to process them but i much prefer doing it in Lightroom. Any help would be appreciated!
Best
TomNothing is “free”. Adding cameras and adding new features is still work performed by people who are paid for their work. Adobe could ask for more money, just a smaller amount, for every single release even if there were no new features, but they choose to ask for more money only for the new features releases. You don’t get the benefit of those of us paying for new feature releases forever, only until a new-features release is available.
Adobe could “support” old versions forever, updating them for new operating systems and new cameras, but how would they pay people to do that work? They’d either need to charge for all those new-OS/new-camera releases, just a smaller amount, or they could charge a lot more for each new-feature-release to pay for those people working on the older versions. But both of those scenarios are less optimal because there are actually more people doing more work so the overall expense is more. Adobe’s major-payfor-upgrades, minor-free-updates pricing model is a cost-effective compromise, but it means customers do have to pay, again, every so often, when the consumer has changed things about their own environment, either new cameras, or new operating systems. -
How to get Fiori fluid design in Non ABAP environment
hi All,
I am very new to fiori, want to use the the responsive lay-outing in business objects product so please help me getting the stating guide for fiori.
In Business objects we have the webapp (tomcat) so how to bootstrap fiori in tomcat??. First of all is my understanding correct about fiori??
Can it be used outside ABAP or SAP context like SAPUI5.
Thanks & regards
KunalHi Kunal,
Fiori uses UI5 libraries (html5) hence it is responsive(adjusts as per the resolution of the screen).
This cannot be used for SAP GUI as we have webdynpro screens and these are non responsive.
Fiori is always placed as a frontend being UI5 application. Business data comes from SAP. If you want to build fiori-like applications. You need an odata service(to be built using SAP Netweaver gateway) and a ui5 application to consume the service. You can either setup eclipse or use WEBIDE.
For more information on FIori : All Things SAP Fiori
For information on UI5 area : SAPUI5 Developer Center | SCN
or What is OpenUI5 / SAPUI5 ?
