QoS Options for leased T1s

Hello, I'm looking for some direction on this.
I have 2 remote sites each connected to our main campus with 4 leased line T1s. There are 2 3845 routers at each site.
I've been giving the task of providing a constant service level for a specific app that runs over these links. I want to develope a WAN optimization strategy that would not only help meet these requirements but also make more effecient use of our WAN in general.
MLP bundling?
Priority Queing?
Custom Queing?
Bandwidth reservations?
I anyone has any suggestions I would love to here them. Since I don't have much experience implementing any kind of advanced QoS I'm sort of spinning my wheels right now.

Hello,
Multilink PPP would be an option, or just put in four static default routes at both sides and turn on CEF.
As for QoS, a class-based scheme is probably your best option. Let's say you want to give 20% of guaranteed bandwdith to FTP traffic, the config would look like this:
class-map match-all FTP
match access-group 101
policy-map PRIORITY
class FTP
bandwidth percent 20
access-list 101 permit tcp any any eq ftp
If you post your configurations and tell me which applications you want to prioritize and how, I can help you with the specifics...
Regards,
GP

CNA QOS options?

My customer has ESXi servers with 2 CNA cards connected to Nexus 5K upstream switches. We will be using the 1000v for the Ethernet portion. Question is, what are QOS options for dividing bandwidth between FCOE and Ethernet traffic? Is there a default split?
Thanks,
John

USe predefined policy maps. It matches frames with cos 3 and allocates 50% bandwidth for FCoE traffic and sets 2158 MTU to FCOE queue. If you are using Nexus 5000 it will automatically apply these policy-maps automatically when you enable feature fcoe.

Options for QoS on 2 meg PPP lease line.

Hi,
I have a 2 meg PPP data lease line bet my HO and BO. I need to know the Qos options, I can configure to run voice over the same link. I want to reserve 384K to voice traffic.
Will auto qos be of any help ?
Thanks

This may help you. Multilink PPP for fragmentation and LLQ will give you what you need.

DHCP - Cannot add text option for VOIP phones in OES Linux

While working through this, I solved the issue, but decided to post this anyway as it may help others to find these sorts of errors.
I'm working on migrating from NetWare 6.5sp8 to OES11sp2. Client has Shoretel VOIP phones. Existing NetWare-based DHCP has no problem. Option 156 has been configured to give out the required text information that Shoretel phones require.
Problem is that I could not get the OES11 DHCP to run with that option. Nor could I migrate the existing option over - the Migration Tool (in OES11) says it successfully migrates DHCP, but I cannot start the dhcpd daemon. Error is that it failed, and in the rc.dhcpd.log file I see an error:
LDAP Line 26: unknown option dhcp.Shoretel_Boot.
LDAP Line 26: unexpected end of file
LDAP: cannot parse dhcpService entry 'cn=newdhcpservice,o=LIBRARY'
Configuration file errors encountered -- exiting
If I look in the file (created when LDAP reads DHCP config from eDirectory apparently) dhcp-ldap-startup.log I can see the problem entry at line 26:
option Shoretel_Boot "FTPSERVERS=172.30.43.8,COUNTRY=1,LANGUAGE=1,L AYER default-lease-time 259200 ;
This option does NOT show up in the newdhcpservice option when I look at it in ConsoleOne, or DSBROWSE, or DNS/DHCP Management Console.
This option DOES show up in the DNS/DHCPManagement Console if I look at the DHCP (NetWare) tab and look at Other DHCP Options for some of the configured subnets, but it actually has different text from the above, specifically:
FTPSERVERS=172.30.43.8,COUNTRY=1,LANGUAGE=1,LAYER2 TAGGING=1,VLANID=9
Note that it does not have a " character anywhere in the entry. This option is configured as a Global DHCP text option.
Novell TID 7009464 mentions the issue, though not for Option 156. In that TID there is this:
"Situation #2
Migrate a working DHCP server with DHCP options that are of type "Text" to an OES server.
Load the DHCP server service... it fails to load and gives similar errors to the ones listed above."
Under resolution the TID says to delete and recreate the dhcp service object without the text option and it will load. That doesn't work for me as I still get an LDAP error pointing to the Shoretel_Boot unknown option. (I dare not try deleting it from the NetWare DHCP config and risk breaking the client's phone system).
One of the options in the TID to fix this is to re-enter the data using the DNS/DHCP Management Console - but that didn't work.
Here is the answer:
First, the log files are misleading. The error message points to not being able to read the newdhcpservice object entry - but the problem was elsewhere. In fact the problem showed up in the logs even when there were no option 156 entries at all in any object inside the newdhcpservice or the newdhcpservice object itself. The problem existed in the NetWare configuration of the object for one of the dhcp subnets.
Specifically, there was an illegal character in the text entry for option 156 - the # character was in there, like this:
FTPSERVERS=172.30.43.8,COUNTRY=1,LANGUAGE=1,LAYER# 2TAGGING=1,VLANID=9
If you look at the error log entry for syntax error you can see that the option 156 text stopped at the # symbol, and then default-lease-time was appended to the end.
Removing the # symbol got things working.

FCoE options for Cisco UCS and Compellent SAN

Hi,
We have a Dell Compellent SAN storage with iSCSI and FCoE module in pre-production environment.
It is connected to new Cisco UCS infrastructure (5108 Chassis with 2208IOM + B200 M2 Blades + 6248 Fabric Interconnect) via 10G iSCSI module (FCoE module isn't being used at th is moment).
I reviewed compatibility matrix on interconnect but Compellent (Dell) SAN is only supported on FI NXOS 1.3(1), 1.4(1) without using 6248 and 2208 IOM which is what we have. I'm sure some of you have similar hardware configuration as ours and I'd like to see if there's any supportive Cisco FC/FCoE deployment option for the Compellent. We're pretty tight on budget at this moment so purchasing couple of Nexus 5K switches or something equipvalent for such a small number of chassis (only only have one) is not a preferred option. If additional hardware acquisition is inevitable, what would be the most cost effective solution to be able to support FCoE implementation?
Thank you in advance for your help on this.

Unfortunatly there isn't really one - with direct attach storage there is still the requirement that an upstream MDS/N5k pushes the zoning to it. Without a MDS to push the zoning the system it's recommended for production.
http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/gui/config/guide/2.0/b_UCSM_GUI_Configuration_Guide_2_0_chapter_0101.html#concept_05717B723C2746E1A9F6AB3A3FFA2C72
Even if you had a MDS/N5K the 6248/2208's wouldn't support the Compellent SAN - see note 9.
http://www.cisco.com/en/US/docs/switches/datacenter/mds9000/interoperability/matrix/Matrix8.pdf
That's not to say that it won't work, it's just that we haven't tested it and don't know what it will do and thus TAC cannot troubleshoot SAN errors on the UCS.
On the plus side iSCSI if setup correctly can be very solid and can give you a great amount of throughput - just make sure to configure the QoS correctly and if you need more throughput then just add some additional links

I cannot see the option for face time of open and close in iphone 4s

Plzzz tell me no facetime option for on and off is nott comming in settings help me plzzz

There is no FaceTime app for the iPhone if that's what you're asking. FaceTime is accessible through your Contacts as one of the options in how to contact a person -- there is no standalone FaceTime app for iPhone.
If you mean how to disable FaceTime, you can do that in Restrictions (Settings/General/Restrictions).

Needing a multi-month and year-in-view option for ical!

Hello all!
I could really use a multi-month and year-in-view format in ical... I've seen some dated posts - is anyone aware of any new developments/options for this?
thanks and peace-
DW

I turn off all calendars but the birthdays. Select [Print]. Choose all the months you want to see. Deselect all calendars but birthdays. Click [Continue]. On the next menu, go to "Layout", select how many pages to print on the paper. I usually print a border around each calendar then you're good to go!
By only printing the birthdays calenar, you won't get too many appointments to get in the way of brain storming and future planning, yet the computer still thinks its printing a useful calendar.

BODS : Datastore options for SAP R/3 - need clarity for use

Hi All.
Another request to understand the datastore optiono n BOXI 3.1 BODS existing installation.
We are trying to pull a new table from SAP R/3 into BODS and we find that ABAP program is not getting generated as expected. And terminates. When we tested a simple workflow.
While creating a new datastore for SAP R/3 Source :
When we look at the datastore we find the following options for R3 Source ;
ABAP Execution option :
Execute preloaded
Generate and execute
Under data transfer method we find ;
Shared directory
Direct download
FTP
Custom transfer
Then we have working directory on sap server
local directory
generated ABAP Directory
Am testing a simple workflow of pulling data from SAP R/3 in a dev machine.
But am not understanding.
which option of ABAP Execution, and data transfer , path would work in co-ordination.
Because when i say direct download and say generate and execute it throws error.
Can anyone help me with combinations of the options to choose for a R/3 source. And the implications thereof.
I had created a folder under local bods server D:\Bodi. And given the path for data transfer.
But the files are not getting generated for whatsoever reasons.
Any advise on this would be helpful.
Also found a bit unusual, that there was no button to test the connection to be correct or not, a TEST connection button is not there. Which i felt, could be included.
Note : on the existing production system, we have chosen execute preloaded; shared directory on sap server. and shared that folder path for the user and given full rights. But while we try to do the same on the dev machine a test before transporting on production, a simple workflow does not work.
would like to know what settings on sap server, really affect the data store options on the BODS
thanks

Indeed, BODS <> SAP connectivity can be tricky.
For a development environment, I suggest you select the option "Generate and execute" for your "ABAP Execution Option." What this means is that DS will create, on the fly, small-ish ABAP programs. These ABAP programs will be written, in plain text, to a local directory on the DS job server, in the folder specified in "Generated ABAP Directory". You can see them in there after an attempted job execution, assuming the job involves the creation of an ABAP program. The ABAP program name is specified in the properties of an ABAP data flow, under Options > ABAP Program Name. If you can't, perhaps the DS job server process doesn't have full rights to that folder - ? After being generated on-the-fly, they'll be transferred to SAP to execute. The SAP user you use to connect to SAP must have sufficient rights to upload-and-execute these ABAP programs, and that's a fairly substantial set of rights. What's required is documented in the BODS supplement for SAP. Often, to get things running, your friendly local Basis admin will grant SAP_ALL to the DS user, to see what rights are being invoked.
Once all that jazz is working, you need to get the data back. There are a number of ways to do this. The method of data transfer is specified in "Data transfer method," where, ignoring "Custom transfer," you have three choices:
1) Direct Download: easiest and slowest. This method tells SAP to attempt to stick data in the client-side folder specified in "Local directory." Try this first.
2) Shared folder: This is recommended when you have SAP being hosted on a Windows box. Basically: you set "Working directory on SAP Server" and "Data Services path to the shared directory" to point to the same folder. SAP uses the "Working directory on SAP Server" to find this folder, and DS uses the other setting. So, for instance, if you were going to use the Shared folder method, you could set "Working directory on SAP Server" to "E:\BODS_Transfer", and, assuming E:\BODS_Transfer was shared-out as "BODS_Transfer", you could set "Data Services path to the shared directory" to
dev12.somecompany.com\BODS_Transfer . Then, you'd need to setup all the relevant security, as both SAP and DS need rights to read and write files in this folder.
3) FTP (this is the method I usually use): SAP writes the "transport files" you're after (i.e., the data) in the folder specified in "Working directory on SAP Server". Then, you need to establish ftp connectivity to that folder from the DS job server's perspective, which you do by entering the ftp host name and the path to that folder in "FTP host name" and "FTP relative path to the SAP working directory". In my opinion, the "relative" business is a little confusing, and I just typically enter the full ftp path, beginning the path w/ a forward slash, like "/usr/sap/tmp/BOBJ" or something like that. You also need to obtain a separate username and password for the ftp connectivity. Note that this name and password has NOTHING to do with the SAP username and password; you're just setting-up DS to act as an ftp client. I strongly encourage you to test ftp connectivity by using a regular ftp client from the DS job server and attempt to connect to your ftp host using the username and password you were given, and attempting to fetch some sample test file. If you can't do this, manually, then DS won't be able to do it, either.
Best wishes,

How do I use my iPad with Retina Display model MD514LL/A with apple tv? I see no option for airplay and I have the latest update.

I am having trouble mirroring my ipad with my new apple tv. I don't see any options for airplay. Any suggestions would be greatly appreciated. Thanks!

Is your apple tv also up to date?
Are they both on the wireless network, or is the apple tv using an ethernet cable?
Reboot your wireless router, your apple tv, and your ipad, in that order.

Is there a key on the MacBook Pro to toggle display options for a projector

I have had some difficulty getting my InFocus projector to consistently work correctly with my MacBook Pro. Is there a key on the MacBook Pro that toggles the options for projector display? There was one on my last MacBook and my previous PowerBook.
Thanks -
Dudley Warner

No, there is no longer a key to control external display modes (it's F7 on my 1st gen MBP, but the option was removed along with the embedded numeric keypad in the Early 2008 models). There's not a substitute keyboard shortcut (with the exception of installing a macro player like Keyboard Maestro). Your main option is System Preferences > Displays (as stated, ticking the box to show Displays in the menu bar provides a helpful shortcut).

Set maximum size in Text Form Field Options for a field in bi publisher RTF

Hi All,
How to set maximum size in Text Form Field Options for a field in bi publisher RTF.
I have a RTF whch is having a field in that i need to add some validation condition but after adding certain condition in Add help text tab ,it is not accepting after certain length, how i can increase the length to unlimited,please help me on this
Thnaks

Form fields have some restrictions if your are using version lower than 11g.
They can accommodate only 393 chars. You can add the text in both status bar and help key, which can in total consume 393 chars.
If your code logic is more than that, it can be split into multiple form fields as Avinash suggested or you can use sub template logic and handle coding over there. Again in sub template code can be within/outside form fields.
So there is no option for user to increase the size of form field.

Message settings option for text messages is not c...

I am using N73 phone and here i cant go to the message settings option for text messages. actually i want to change my message center.

My ipod nano 6th gen fell out of my pocket and the screen cracked badly, is there any coverage for this under warranty? I just bought it a month ago. If not what are the options for getting it fixed? It is pretty frustrating, it fell from about 3 feet out of my pocket and now looks like it was beaten by a hammer.

Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.

If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
If DU reports errors it cannot repair you will need touse autility like TechTool Pro,Drive Geniusor DiskWarrior

How do I remove a credit/debit card from my account? I ask because I currently have a VISA gift/debit card with 50 dollars on it, but the money has run out so I want to usea new card. Also, there is no 'None' check option for payment type on my account.

Depending on how you created your account, "None" may or may not be an option. I believe it has something to do with whether the account was made through an App Store request or the regular iTunes Store. For example, my account allows no card but my father's doesn't allow there to be no card.
To change the card, go to your account settings and change the information to your new card, and hit save.
