Different channels for different SSID's?

Hi all, we have multiple WLANS/SSID's on our controller, which are broadcasting on all AP's.
Is it possible to configure the AP's to broadcast the SSID's on different channels or is this not necessary/usefull.
Do the 2 SSID's interfere?
Thanks in advance!

Two ssids are fine. The more ssids you create, the more beacons in the air. Cisco had a best practice of no more than 4 if possible especially with older devices on the network. It doesn't mean you can't have more.

APs using different channels for the same SSID

Hi,
This might be a stupid question, but I am wondering why my Aironet 1602i and 2602i access points connected to the same controller would use different channels for the same network. Would this be to avoid interference? If so, I am planning to put 9 access points throughout the office and they will be fairly close to each other. Would this increase the risk of interference?
Thanks,
Tibet

That is normal. The WLC is determining the best channel and being in different channels is the best. When you add more, the WLC will decide by the use if RRM what channels and power levels to allocate to each AP.

How to re-use one SOAP Sender Channel for two different messages?

Hi!
I have an XI Proxy to SOAP Sync Scenario. 5 messages uses only 2 channels - cc_XI_Sender and cc_SOAP_Receiver. All messages comes from one Sender Channel and goes to one Receiver channel, and it works fine.
When I make the same for SOAP to XI Proxy Sync Scenario, I've got a problem. For example I have 2 different messages (mi_so_MSG_ONE and mi_so_MSG_TWO), so it works, if I had a two different sender channels (cc_SOAP_R1 and cc_SOAP_R2).
If I set the same Sender Channel in both Sender Agreements (cc_SOAP_R1), only one message (mi_so_MSG_ONE) goes without errors. When I send a second message (mi_so_MSG_TWO), in SXMB_MONI this message comes from Business System (BS_TEST) as message type one (mi_so_MSG_ONE), and then in stage of transformation in Interface Determination goes to message mapping program for other kind of messages (MM_MSG_ONE_to_XI_PROXY). And then - error in message mapping.
I try many URLs for both messages:
1) http://host:port/XISOAPAdapter/MessageServlet?channel=:BS_TEST:cc_SOAP_R1&version=3.0&Sender.Service=&Interface=
2) http://host:port/XISOAPAdapter/MessageServlet?channel=:BS_TEST:cc_SOAP_R1&version=3.0&Sender.Service=BS_TEST&Interface=*
3) http://host:port/XISOAPAdapter/MessageServlet?channel=:BS_TEST:cc_SOAP_R1&version=3.0&Sender.Service=BS_TEST&Interface=...MyNameSpace...mi_so_MSG_TWO
Message in payload:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<MSG_TWO xmlns="urn:xxx:yyy:MyNameSpace" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">... some fields... </MSG_TWO>
But in SOAP Header I see that is NOT second message!
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
< !-- Inbound Message   -->

Is it correct that many kinds of messages cannot goes through one Sender Channel ? If not... How can I reuse one SOAP Sender Channel for both this messages?
Thanks for helping.

Thanks for answers!
It means a webservice application will be deployed and exposed in PI using the associated Message Interface and its namespace information in the SOAP Sender channel.
It means only one Sender Channel per one pair of names (name of Message Interface and name of namespace). And it will fail if I change something. And question is: why URL for sending SOAP message contains parameter "Interface"?
"backward compatibility" or "for future use only"?
Nothing happens when I change this parameter, seems that name of Interface comes from first of founded Sender Agreements.
If the structures are the same
No. Structures are different.
Making one structure per all SOAP incoming messages looks workable, but... looks strange (in fact I have a lot of SOAP messages, more than 100 Sender channels).
I found an information, that I can use one Sender channel per many messages with different structures only if I make this messages like different Operations in one Service Interface (in PI 7.1).
But in this case in list of messages in SXMB_MONI I will see only a one name of Service Interface for all my messages and it's not so comfortably for supporting: to take a name of operation that fails I need to goes inside.
In older version of XI (prior 7.1) using one sender channel per many messages allowed without any hints.

Design: different AP Groups for different SSIDs?!

Imagine I have different requirements for the AP Groups for different SSIDs
I suppose I can't have different AP Groups for different SSIDs?!
Imagine I have to many Clients to use one single VLAN for one SSID. So I will use AP Groups.
For SSIDâXâ
Let's say I have 5 buildings with 800 Users, so I make a AP Group per Building and tell those APs that they are in that group.
For SSIDâYâ
All though I have this SSID also in all 5 buildings, I only have very view Users, so I could make one single VLAN which makes everything easier.
Am I obligated now to create 5 VLANs for SSIDâYâ too?!
*This is a made up example. In reality I would make different numbers of AP Groups for different SSIDs because I have significantly different number of Clientsâ¦ and traffic characteristics (more or less broadcast).
But it's also about the size of the VLANs, do I make a view large Broadcast Domains (VLANs) or more small ones.
Greetings, Andi

You can have a setup like this if you want:
AP Group 1
SSID X Vlan 10
SSID Y Vlan 21
SSID Z Vlan 31
AP Group 2
SSID X Vlan 10
SSID Y Vlan 22
SSID Z Vlan 31
AP Group 3
SSID X Vlan 10
SSID Y Vlan 23
SSID Z Vlan 32
AP Group 4
SSID X Vlan 10
SSID Y Vlan 24
SSID Z Vlan 32
AP Group 5
SSID X Vlan 10
SSID Y Vlan 25
SSID Z Vlan 33
AP Group 6
SSID X Vlan 10
SSID Y Vlan 26
SSID Z Vlan 33

Controller different ssid

Hello all
i use cisco controller and LW access-points.From one access-point i broadcast two SSID.Is it possible to change wireless channels for different SSID ?
For example in one access-point SSID 1 is wireless channel 6 and the other SSID is 11 ?
Thanks

Hello.
You can only have one channel per radio.
on 2.4 GHz radio, you can NOT have different SSIDs on different channels.

The iTune Remote App has stopped finding my iTunes library when connected to wifi from my main router, but works fine when connected via second wifi router on the same network (different SSID)

I'm running iTunes Remote App from a couple of iPhone 5's and a first generation iPod Touch. iTunes is running on a PC - Windows 7. My home network runs two Wifi Routers, each with a different SSID. I've had no problems with the Remote app running this set up for the last 8 months but recently the App can only find my iTunes library when the iPhone/iPod is connected via one specific router, when connected to the network via the other router, no iTunes library is found. I'm also running an Apple TV and it's the same as the iTunes Library, only visible via the one SSID.
Everything else seems to work fine when connected via either router, eg Internet on the iPhones (definitely via wifi)
I've tried renewing the lease on the iPhone wifi connection, restarting everything.....several times.....
It used to work fine, this only seems to have been a problem in recent weeks
Any help or advice would be much appreciated
Thanks
Ian

It turned out to be the firewall settings on our router. Her machine was sending traffic that our router interpreted as a DoS attack and blacklisted her Airport's MAC address. That's why it would work fine if she switched to Ethernet.

Need help configuring: 2 wireless routers with 2 different SSID's on one network

Hello everyone:
I've been reading around on the forum trying to find the answer to this question, but have not found any clear cut answer that satisfies all my requirements. A more in-depth explanatiion.
I have 1 IP address coming in via cable modem. I want to configure two wireless routers (one secured with WPA-TKIP, and one unsecured--a "guest network" if you will) each with different SSID's. The secured network would be for my server, home PC's, IP webcams, DynDNS updating; while having an unsecured wireless router that friends and family can access. Ideally, I do not want anyone who accesses the unsecured wireless router to be able to get access into my secured network.
Can someone please tell me if this is possible. I think it is based on some posts I have already seen, but specific details about how to do it would be appreciated. Additionally, my DynDNS has to still be able to update with my ISP's IP so that I can access my server and home webcams.
EQUIPMENT
2 - WRT54G
1 - EZXS55W
1 - WVC200
1 - WVC54GC
(all of my stuff --webcam, server, dyndns, etc -- is working currently on my secured network. I just need to add the unsecured network)
I know this is a lot, but I would appreciate any help. THANKS.
Solved!
Go to Solution.

You must have the main WRT54G router connected to the modem. Set up the secured wireless network on the main router. Connect all your wireless computers or devices to the main secured wireless network.
Let's consider the IP address of the main router is 192.168.1.1.
Now connect only one computer to the Port 1 on second wireless router.
Open the setup page of the second wireless router. Change the wireless settings, SSID, unsecured.
Change the IP address of the second router to 192.168.2.1. Save the settings.
Connect the cable from the Ethernet port on the main router to the Internet port on second wireless router.
Power cycle the second wireless router.
Now the guest computers connected to the second wireless unsecured wireless network will be able to access the Internet only. They will not able to see the computers or devices connected to the first wireless router.

Cisco WLC 5508 assigning different SSID to few APs

Hello Everyone,
I have a WLC 5508 runing 8.0
Presently one SSID is assigned to all th APs registered with my WLC.
I want a different SSID to 2 of APs. Can anyone tell me how to do this?

Depend on WLAN ID number as well.
1. if WLAN ID number is greater than 16, then those SSID not visible in "default ap-group" & only in the APs in particular AP Group.
2. if WLAN ID number is lower than 16 then, by default it will advertise in APs in "default ap-grop". So if you add that WLAN to particular AP Group, then that WLAN advertised by APs in both AP groups (default & specific AP group)

AirPlay with two different SSID's

If I set up a small apple network (two airport extremes & 2 apple TV's)
- SSID = 'apple'
and then add a 3rd party wireless access point that broadcasts two different SSID's.
-SSID 1 = 'apple' (identical settings to 'apple' configured on airport extreme dev
- SSID 2 = 'banana'
Will the wifi clients on 'banana' be able to airplay music/movies over to the apple TV's on the 'apple' ssid?
Thanks in advance.

Will the wifi clients on 'banana' be able to airplay music/movies over to the apple TV's on the 'apple' ssid?
Yes, if the wireless access point is configured to operate in bridge mode. Then all clients on "apple" and "banana" will be on the same network, receiving IP addresses in the same range from the same network router.
In simpler terms, "apple" is one door and "banana" is another door. Both doors open into the same room.

How do I create a group of channels for input to a AI multi point

Hi,
How do I create a group of channels for input to a AI multi point, so that I can output it to 3 different graphs.I figured out the graphs but I am not able to figure out how to create the group of channels for the input.I saw many examples where a group of channels is given as an input.

hello
You have to put Daq Mx Create virtual channel.vi in a For loop. out side that u should give an array of virtual channel which ever you need to acquire. i am sending the vi in 7.0 too.

How to create a new channel for a role or an organization using API

Hi all,
I tryed to create a new channel using the method createChannel(...)+ in the class ContainerProviderContext+ of the package com.sun.portal.providers.context+ and everything is fine. The channel is created under the display profile of the authenticated user who asked for the new channel.
But I'd like to create new channels for other users/roles/organizations. Does anybody know how to do that???
Thanks in advance.

Hi Juan,
Yes you can use JDBC adapter to integrate with DB2 but you need to deploy the DB2 drivers.
Possible options to integrate with DB2 are :
We can integrate DB2 system with XI using different methods :
a)For batch mode we can work with standard file adapter of XI
b)Install MQ Series and use JMS Adaptersto send and receive messages with DB2
c)Use the JDBC Adapters to directly write to the DB2 Database.These is for
incoming interfaces
d) Third Party Adapters provided by iway can also be utilized ,but it requires a separate license

ACK_ channel for handling ALEAUD back to ECC system

Hi,
I have created a channel called ACK_Receiver_XI_TO_ECC for sending ALEAUD for all IDOC's that are received from ECC to XI. I also have another receiver IDOC channel for all IDOCs that are sent from XI to ECC. I read in one of the pdf's that when there are multiple receiver IDOC communcation channels, the one starting with Ack_ is chosen to send the ALEAUD. But in my case, in Development and QA system it is correctly picking the Ack_.. channel but in production it is picking the other receiver IDOC communication channel. Any ideas why and how this can be rectified? I have the "Restore original parties.." option checked on the Ack_.. one and not on the other so the selection of the other in production is giving me the "Unable to convert sender service to ALE logical system" error.
Thanks
ram

Hi Ram,
>I also have another receiver IDOC channel for all IDOCs that are sent from XI to ECC. I read in one of the pdf's that when there are multiple receiver IDOC communcation channels, the one starting with Ack_ is chosen to send the ALEAUD
I dont think so, the channel will be determined by the Receiver Agreement. If you have more than one what are valid for a message, that is take which is less generic. For example, if you have 2 Receiver Determinations and you type in the first at Receiver Interface a joker (*) and in the second for Receiver Interface a certain value the second Receiver Determination will determine the channel. This is a general rule for IB objects and allows to create generic rules but having exceptions.
Please compare the Receiver Determinations in the different transport layers.
"Unable to convert sender service to ALE logical system" means, that your sending system has no value for logical system. Control that at Business Component, Adapter Specific Identifier. If the sender is Business System, correct that at SLD and reimport the system.

Udo

One or two LAG port-channel for 5508 v7.4 in HA setup?

Hi group
I have a question regarding LAG in HA setup; do you configure two port-channel, one for each controller or, only one port-channel for both?
I have a stack of 3 x 3750x, and 2 x 5508 with each two Gigabit uplink in use.
Active controler (5508-1) is connected to stack switch 1 and stack switch 2.
Standby controller (5508-2) is connected to stack switch 2 and stack switch 3.
I cannot find any documentation or guidelines for configurations of LAG in HA setup.
P.S. my question is not how to configure LAG or LACP, it only if you use one port-channel consist of 4 gigabit ports, or you have two with each 2 gigabit port to each controller.
TIA,
Peter

Thanks Stephen for your reply.
The switch doesn’t see which of the two port-channel that is on the active controller right?
If WLC01 is the active one in PO1 and standby is WLC02 in PO2, the MAC of the active controller (WLC01) will be sending on PO1.
When failover to standby, the MAC of WLC02 will be sending on PO2. As I see it, it is same IP address (management IP address of WLC01) but different MAC address – from WLC02.
So why could it not be one Port-channel, both controller will use one and same config when it become active?
TIA
Peter

Problem of Creating Multiple Communication channels for multiple files

Hi Everybody
I have a very basic doubt but this struck me...
For a file-XI-file scenario,if multiple files are coming from same FTP server but with different names then we have to create multiple communication channels for all the files of different names..but is this a intelligent approach?Can we do something so that only one communication channel can receive multiple files of different names?plz explain in detail if possible ASAP.
I have another doubt as in File-XI-File scenario how the XI understands that a particular file is from this FTP server needs to be send to another particular FTP Server?is it only the name of the file which we give in sender comm channel & receiver comm chaneel which determines this????that means this name should always be same?plz explain in detail if anybody knows?

Thanks Aamir.I understood the solution.
Correct me if I am wrong.......
1)If there are multiple files with different names & different extensions in the sender FTP then we use-->
2)if there are multiple files with different names & different extensions in sender FTP & I want only say files of 2 extension types(say .xml & .txt)then we use-->
*.xml
in one comm channel &
*.txt
in another comm channel rite??
Also I wanted to ask that only two kinda files we can pick up through sender comm channel rite?
.xml and .txt(File content Conversion).Can we pick files of other extensions also?(say .doc,.xls)If we use as u said
then files of all other extensions will also be picked up rite?bt hw will xi convert them into xml?plz explain......
One of my other q is not answered yet.........all these same doubts are there for receiver communication channel.......but you all have not said nething abt the receiver comm channel........plz explain the answers to all these queries for receiver comm channel for a receiver FTP........ASAP......thanks once again.......

Large Subnet for single SSID

I am looking for a design guide to help me split up a large subnet for a Cisco Wireless network. We have a Campus with a centralised Wsim and a single SSID. We are hoping to be able to keep the single SSID but split the subnet as it is now quite large and we would like to reduce the broadcast domain to a manageable size. I have found a number which have different SSID but we would like to keep only 1 as it simplifies the user experience.

Adding to Scotts post. If you are doing 802.1x you can use dynamic VLAN assignment to achieve the results as well.
AAA returns attributes 64/65/81 to the WLC, to change the VLAN the user gets put into. You do still need to create the dynamic interfaces on the WLC.

How to place outbound files to multiple channels for a single agreement

Hi All,
We need to send single HIPAA 834 document to two different locations(channels) of the same TP. We have single HIPAA 834 agreement with one TP and one channel. is there a way to add two TP outbound channels for a single TP/agreement?
Thanks,
Kathar

Hi Kathar,
is there a way to add two TP outbound channels for a single TP/agreement?One TP may have multiple channels but one agreement can have only one associated channel. You may consider using the broadcast feature of Oracle B2B here.
You may read about this feature here -
https://blogs.oracle.com/oracleb2bgurus/entry/broadcast_feature_in_oracle_as
Please note that this blog was written for 10g but concept and implementation is same in 11g.
You need to create two TP profiles for same TP (you should use different name/identifiers for both) and then make them part of same group by adding identifier "Grouping" in both the profiles with same value. From middleware pass the header "Grouping:<value>" in action name or event name header. At runtime B2B will send the same message to both TP profiles.

Anuj
