Channel configuration on dual SSID

I am installing a few aironet around a environment which requires dual SSID one for Guest and the other for business.
When configuring the channel for each SSID should I make both SSIDs on the same aironet the same channel and then ensure the closest aironet with the same dual SSIDs is both on the same but different (non-overlapping) channels ?
Or should both SSIDs on each aironet be on different channels?
Thank you.

Channel selection ... Hmmmm ... autonomous IOS ... Not a good combo.
I mean the issue here is your 802.11b radio. If you have neighborhood wifi around, smart money 802.11b is being used and Channels 1, 6 and 11 are used too. No issues with 802.11a since there are more channels to play with.
It's OK if you have a WLC because of the Dynamic Channel Assignment feature. But with autonomous WAP, you need to constantly monitor your neighbor.

Creating Dual SSID's

We are running phat architecture (WLSE, ACS, 1230 AP's) and PEAProtocol. I want to create additional SSID's on every AP (WPA-PSK) for vendors.
My questions is this: "Are there any good documents that discuss the creation of dual SSID's, VLAN/AP configuration, and/or best practice approaches?"

Hi Darin,
jep there are some documents.

How do you get IBM Access Connections on T41 to remember channel of weak signal SSID?

I have a T41 with Windows XP SP2. It uses IBM Access Connections to connect to wireless networks.
How can I get IBM Access Connections to store the channel used by an SSID, so that it won't roam through all channels over and over looking for a better channel?

i seem unable to setup the AE to do the same thing. i can stream audio to my hifi no problems - this is cool. i can set it up to create a wireless network and give it a different ssid and channel but it doesnt seem to want to choose the same ssid. i can manually change it to the same - is this what i should do?
Yes you will manually need to enter the SSID.
however when i do this the AE trys to act as DHCP and gives a 10.1 address to the laptop which is odd
You also need to configure the AirPort Express (AX) to bridge (not share a single IP address).
should i be using the join a wireless network option instead of the create a network? but isnt this for people who are extending their networks wirelessly?
You should be using the "create a network" option.

B2B outbound Channel Configuration - EMail - Attachment Name and Extension

Hello,
I have configured an outbound channel to send the payload (xml) as an attachment. When I leave the "Subject" field in the Channel configuration blank, the attachment file name looks like this,"HostPartnerName_TradingPartnerName_DocumentType" without the file extension. If I supply the "Subject" field with the value, the file name gets replaced with the subject and the file extension still is missing.
I would like to receive a file name in a format like "batch_b2b.messageId.xml". The property b2b.messageId gets the value from the Mediator. The composite that passes the information like the b2b properties has been made generic to handle different Trading Partners, so for a channel that uses SFTP, I have used the Filename format and supplied the value as "batch_%MSG_ID%.xml". Is there a way I can do the same for Email channel?
Thanks,
Venkatesh

Hi Venkatesh,
Attachment name can be set from the middleware using below header (as per the mode of integration used) -
1. For AQ mode of integration, use actionName -
actionName=ATTACHMENT_NAME:test.txt
2. For JMS mode of integration use custom JMS header - jca.jms.JMSProperty.ATTACHMENT_NAME to populate the name.
3. For fabric (default) mode of integration, use b2b.attachmentName header

Anuj

WAAS Port Channel Configuration

In the recent weeks we got some reports that CIFS writing performance to NETAPP OnTap 7.3 filer was degraded for WAAS accelerated connections. NETAPP OnTAP 7.2 and native Microsoft filers were running fine. In our Testlab we could correlate this issue with the port channel setup on our WAAS devices. With round robin (standard setting) the CIFS writing perforamce was poor. By switching the port channel loadbalancing to src-dst-ip-port the performance was excellent.
Is there any known best practices recommendation for port channel configuration on WAAS devices?
Many thanks in advance, Peter.

The best practice depends on your network. Most deployments are fine with the default round robin configuration for port channel on the WAE. But I have encountered some installations where the configuration had to be changed in order to avoid out of order packets causing slow performance (like, if there is a firewall between the WAE and the server).

Configuration for dual-band WLAN?

I have an X230T with Intel N-6205 and 2x2 antennas. AFAIK it is capable of parallel WLAN connection on both the 2.4 & 5 GHz for maximum bandwidth. How should I configure my WLAN to take advantage of this. Should both 2.4 and 5 GHz networks have the same SSID?
X320T running Windows 8 Pro x64

Actually, those settings I provided you are from my Intel Dual Band Wireless-N 7260 adapter so some settings are a bit different, but it should work for all Intel Wi-Fi cards.
rsbrux wrote:
"I also have a secondary router, whose 2.4GHz radio I had set to 20 MHz BW, as there are more other 2.4 GHz WLANs near it. ISTR reading that the narrower BW can actually yield improved throughput under such conditions, and the secondary router has no "auto" BW option. What do you think of this?"
P.S. If I understand "NS offload for WoWLAN" correctly, it seems to be enabled.
At least, the WLAN adapter appears to turn itself on, even with the laptop powered down and connected to a wired ethernet.
As billbolton pointed out, he is 100% correct that "The 2.4GHz WiFi band has become so congested with competing traffic in many densely populated locations that useful 300Mpbs connections are quite unlikely to be achieved."
Based on many networking articles, 300 Mbps is achieved through channel bonding (40 MHz) on both bands. Since channel bonding makes the channels wider, this would actually result to more overlapping with other channels from routers nearby on the 2.4. Channel overlapping should be avoided since it induces more interference thus making your ping spike often as well as frequent reduced throughput and link speed. On the worst case, you will experiece dropped connections. If you absolutely have to work on the 2.4 GHz band with a lot of neighors, you can leave the Wi-Fi adapter settings I provided to be the same, but you have to change the channel width on the router to 20 Mhz only for 2.4 GHz band and leave the 40 MHz channel width on the 5 GHz band. This would cut the speed to 156 / 150 / 144 Mbps on 2.4 GHz band only, but you only occupy 2 adjacent channels from the channel you're broadcasting instead of taking over more than half of available channels using 40 MHz. Like many networking articles online, 40 MHz is ideal for 5 GHz since very few people use that band and there are far more available channels to choose for the 5 GHz without overlapping with other channels nearby.
As for your PS note, the reason the WLAN adapter is awake while the computer is asleep is due to Intel Smart Connect Technology: http://www.intel.com/content/www/us/en/architecture-and-technology/smart-connect-technology.html

Port channel configuration with VMware

Hi everyone, I have dual 6120 interconnects, each of which have two uplink ports. I also have two Catalyst 4900M switches to uplink to. So I plan to configure both 802.1q and 802.3ad on each of the 6120 uplink pairs. My question relates to the physical cabling, bearing in mind ESX will be running on the blades.
Would you cable both the uplink ports on interconnect 1 to switch 1? Or would you cross-connect them to both switch 1 and switch 2?
As per this article I see ESX does not support splitting a port channel across two switches, but I am unsure how the presence of the 6120s affects this. Can anyone suggest the best way of doing the cabling based on the kit I have? Thanks.
http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=1001938&sliceId=1&docTypeID=DT_KB_1_1&dialogID=14912551&stateId=1%200%2014916516

Hey Simon, let's address this is two parts because there are two layers: server-bound (ESX-6120) and north-bound (6120-Cat4900).
At the ESX end, use the default srcPort in the vSwitch / port group with both 10GbE uplink ports (vmnic0 and vmnic1) set to active (not active/passive). There are no loops in this configuration. On the VNIC (in UCSM) you select trunk port and allow all the VLANs that your vSwitch port groups needs. If you don't use a VLAN for the Service Console/ESXi Management, then make sure you set Native to the correct VLAN in the VNIC to allow untagged traffic down the right path.
At the 6120 you can't explicitly configure a trunk for border ports, they are already set so and when you add VLANs they are added to every border port trunk configuration. You, of course, need to make sure the Cat4900 ports at the other end of the cable have the same trunkport VLAN configuration.
So in summary - set VLANs in vSwitch port groups, VNIC in UCSM and northbound switch.
Now when it comes to port channels, you can only configure two or more border ports as a port channel if they are cabled to the same Cat4900. If you had Nexus 5k/7k northbound then you could use vPC on them to allow "mesh" cabling (ie. one 6120 connects to both Nexus switches). But as you aren't using Nexus you will end up with a configuration as Jeremy explained:
ESX --> vSwitch0 --> srcPort load balancing --> 2 active uplinks --> many port groups
6120-a --> Cat4900-a
6120-b --> Cat4900-b
However, I would still recommend using a couple of border ports in a port channel on each fabric to each Cat4900 because, if you pull out a cable/lose a port, then when that port is re-enabled the existing live traffic is redistributed whereas without the port channel only new traffic will be spread across both links.

SATA/IDE channel configuration issues

Ok here's the setup:
First SATA Channel: Seagate 7200RPM 80GB HDD
Primary IDE Channel: LG 52x CD-ROM Drive
Secondary IDE Channel: Western Digital 7200RPM 160GB HDD
OS: Windows XP SP1
Mobo: MSI 865PE Neo2-P MS-6728 Version 2
The bios can detect all drives.
If I use the recommended On-chip IDE Configuration mode as mentioned on page 3-23 in the manual, Windows XP loads and then goes through the process of detecting the Primary and Secondary IDE channel.
After detecting it reports that Windows reports that the "Driver is not intended for this platform".
If you look under Administrative Tools in Control Panel is refuses to detect the PATA drive as well.
I tried swapping the PATA and the CD drives around but the above applied.
If I try the following drive configuration and set the bios ATA Configuration to PATA & SATA then all drives are detected in Windows:
First SATA Channel: Seagate 7200RPM 80GB HDD
Primary IDE Channel Master: LG 52x CD-ROM Drive
Primary IDE Channel Slave: Western Digital 7200RPM 160GB HDD
So what's up? I've tried tinkering around with Legacy/Native, PATA/SATA Only etc and I've run out of ideas.

I got similiar problem as b52 when I plugin an old P-ATA deathstar drive as master on first primary IDE and a LITE-ON dvd-rom as master on secondary. When I enter Windows the hardware auto wiz starts working and after a little while reports that two devices of type "IDE channel" have "Driver is not intended for this platform". I currently use the settings Danny recommends above. Weird thing is both the deathstar and the LITE-ON drive seem to work great. Of course I want to get rid of the exclamation marks in my device manager though. I read elsewhere drive emulation software could be a culprit, and renaming/deleting atapi.sys could be a problem solver - but not for me it turned out. Anyone got other methods to try out?

Verification of recvr file channel configuration without sending a message

Hi,
We need to test the configuration((such as directory, filename etc.,) of a receiver file channel. As we all know, in the case of sender channel, since it will keep polling the directory configured, if there is any incorrect directory, it will be indicated in the run time work bench, EVEN IF THE MESSAGE HAS NOt GONE THROUGH THE SENDER FILE CHANNEL. However in the case of receiver file channels, UNLESS THE MESSAGE GOES THROUGH THE RECEIVER FILE CHANNEL, we won't be able to identify the incorrect directory configuration.
Thus, please let me know as to how to identify the incorrect directory configuration in the case of RECEIVER FILE CHANNELS, without sending any message through the same.
I appreciate your early response.
Regards
Venkat

Hi,
AFAIK you can check whether the channel is Started/ Stopped (in RWB), check whether correct parameters are filled in the CC (by visual inspection)....but unless and until you test the scenario you may not know whether the CC is properly working or not....somethimes there is a case that you are asked to pay for each and every message that is sent using XI...is this your case?....if not then you can go ahead and test it end-to-end as Dharamveer said.....
If you get the solution (as you need) then dont forget to share with us

Receiver mail channel - Configuration of email id's

Hi,
I am using mail package in receiver mail channel. Is there anyway that we can configure the 'To' email id's in the integration directory with mail package being used (either by adding some entries in the module/identifiers tabs etc., ?
I don't want to have the email id's to be taken either through mapping or property file etc.,
I appreciate your reply.
Regards
Gopal

Hi RGopal,
If the payload is in mail package format, the header information is used for the e-mail. For that make the entries for mail attributes (From, To, Subject).
Specifications for mail attributes:
1.On the Parameters tab page of the communication channel you have created newly or the existing one ; select the adapter type Mail.
2.Then select the Receiver radio button to define the adapter as a receiver adapter.
○       Under From, specify the e-mail address from which the message is sent.
○       Under To, specify the e-mail address that will receive the message. If you enter more than one address, you must separate them with a semicolon.
                 If you have specified an IMAP server under URL, the message is saved in the specified folder but is not sent to the receiver specified under To.
○       Under Cc, specify the other e-mail addresses to which the e-mail is to be sent.
These addresses are visible to the receiver.
○       Under Bcc, specify the other e-mail addresses to which the e-mail is to be sent.
These addresses are not visible to the receiver.
○       Enter the Subject of the e-mail message.
○       Specify whether you want to encode the content of the e-mail message. You have the following options:
■       None
■       Base64 (default value)
■       quoted-printable
○       If you have selected XIPAYLOAD as the message protocol and you want to forward XI attachments in the e-mail attachments, select Keep Attachments.
You use the PayloadSwapBean module to swap the application payload with one of the attachments.

EDI X12 File Channel Configuration

Hello B2B Gurus,
I am trying to configure the following scenario on a single host to simulate trading partner communication using EDI X12 4010 850/810 over File Channels:
Inbound - 850 PO From RemoteTradingPartner to HostTradingPartner
I have configured a file delivery channel on the partner configuration screen under the "channels" tab. The channel is named: "RTP_File_Receive_Channel".
The channel has the following values set:
Polling Interval: 5
Folder Name: /home/oracle/b2b/remote/b2b_receive
Filename Format: %FROM_PARTY%_%DOCTYPE_NAME%_%DOCTYPE_REVISION%*.dat
Directory Name Format:
Minimum Age:
Archival Directory: /home/oracle/b2b/remote/archived_b2b_receive
I am dropping a file named RemoteTradingPartner_X12_4010_850.dat into the /home/oracle/b2b/remote/b2b_receive folder but for whatever reason, it is not picking it up and sending it to my SOA composite.
Should I be configuring a listening channel in the Administration tab instead of a delivery channel on the trading partner agreement? The naming convention and direction of channels is a topic that confuses me no matter how many times I go through this.

Hello Johnny,
When Oracle B2B receives a transaction either from internal application (outbound) or from a trading partner (inbound), it first identifies the trading partner and then the transaction set. This combination is then used to identify the agreement.
What segment/element values within the .dat payload are introspected to lookup the appropriate trading partner agreement? If I specify those values in the filename format, does it override what is inside of the payload? In general, how do filename format, directory name format, and payload contents work together to resolve to the correct TP Agreement? What is the order of precedence when these values are specified in all three locations.The method for identifying the trading partner and transaction varies among transport, exchange and document protocols. If file name format is specified in the channel then Directory name format is ignored. If file name format/directory name format does not give info about transaction set (doc type and doc type revision) then payload is used to identify the document and it's version. It depends upon the type of document standard used that which selection criteria should be used. Generally for xml payloads x-path is used to identify a document and for non-xml payloads either start and end position are evaluated or the position of a particular element/string.
In short if you give all info for identifying an agreement (From tp, Doc type, doc type revision) in file name format/directory name format, then payload will not be checked for identifying any of these.

Anuj

Sender File Communication Channel Configuration

Hi guys,
We are trying to develop a file-to-Idoc scenario and we are facing some problems in the configuration of the sender file communication channel as far as the file format is concerned. The file, which is a material master file has the following structure:
00.00 FileHeader
30.00 Material n° 1
30.01 Material n° 1
30.00 Material n° 2
30.01 Material n° 2
30.00 Material n° n
30.01 Material n° n
99.00 FileFooter
Initially, I developed 4 datatypes, FileHeader, Record1, Record2 and FileFooter, and 1 datatype to incorporate all of these, but I faced trouble in 'Recordset Structure' attribute in communication channel, where "FileHeader,1,Record1,,Record2,,FileFooter,1" did not work.
After that I thought of creating one more datatype, called Record, with 0..* cardinality, that incorporates Record1 and Record2 with 1 cardinality.
Although I have declared them correctly as "FileHeader,1,Record,*,FileFooter,1" in 'Recordset Structure', I face trouble in the table with the attributes. What shall I use: I have Record1.fieldNames and Record2.fieldNames and fieldFixedLengths, but XI requires Record...
What you suggest?
Evaggelos

Hi,
I understand your problem....
I actually didn't look at the key fields...properly..
You have said that when you had tried taking Record1 and Record2 in your structure you had problems...
I think the second way which you are trying would not work..!
Can you try this..I am not sure if it will work..
Have your structure as
MT
+Record
++Header
++Record1
++Record2
++Trailer
So your Recordset name would be :Record
RecordsetStructure would be Header,1,Record1,,Record2,,Trailer,1
and then all the other parameters like fieldNames,fixedFieldLength,keyFieldValue...for Header,Record1,Record2,Trailer
U might just try out with this

Manjusha.
