CS11800 - Can I have a SPAN port for my IDS box?

I have a network design that calls for a few CS11800s and it's smaller brother. The security team has asked if this content switch has a SPAN port that is availble so we can hang our IDS box off.
Thanks

I am not extremely familiar with the CS11xxx series and its configuration options, but I can tell you that from experience with Cisco Catalyst switches and non-Cisco IDS devices a SPAN port is not always the best solution. In some instances I have had to disable packet learning in the SPAN session, and in other cases I have had to forego using SPAN at all and settled for an uplink to a hub that connected the IDS device and my router(s). This is especially true if the IDS device needs to be a member of the same VLAN as the traffic it is monitoring in order to send RST packets back onto the segment.
I have researched this issue on my own and even opened TAC cases for a solution, but have received solutions ranging from "There's no reason this shouldn't work" to "You can not set up a SPAN session for IDS purposes." My recommendation would be (even though it does decrease performance a bit) to implement the hub solution, regardless of the CS11800 capabilities. This will prove to remove any potential X factors in the SPAN functionality and make your life a lot easier.
Just my 2 cents. :)

Hi,
>>>>>1. Is it necessary to keep both XI and SAP Logon in the same system?
XI consists of two stacks - java and abap
so to access XI you also need sapgui
otherwise you won't be able o use XI
>>>>2. Do we have any other alternative to find out the port?
a) ask someone who installed this system
b) if you know the system number of your XI
then you can try: http://xiserver:5XX00
where XX is the system number of XI

Can you no longer have a background color for the text box in the new version of hp photo creations

just updated to the new version of HP Photo Creations, used to be able to have a colored background for the text box - is that no longer possible in this new (not better) version????!!!!! Uuuuuuuuuugh

Hi Lainey.
Thanks for asking. We're working on bringing back that feature. In the meantime, here's another way to add text backgrounds: Add a placeable graphic and then click the Arrange button to send it to the back, behind the text.
That approach also gives you more interesting shapes. The new alignment guides make it a snap to align a graphic with a text box. In the example below (it may take a day for the image to show up here), I also used the new Premium Editing Features to change the color of the graphic.
P.S. — Applying a thick border to an empty text box (also using the Premium Editing Features) is another way to create a background shape. That has the advantage of letting you pick any color for the box. You'll also find several new text styles at the bottom of the new text menu.
Let us know if we can help further,

Can I have diff transacton Variant for the same tcode?

Hi Experts,
Can I have diff transacton Variant for the same tcode? If so i will i assign it to diffrent users.?
Requirement Details:
I have three diiffrent roles accessing XK02.
I need to provide diffrent transactions variants for these 3 roles, through Variant groups. How will i do this?
When i tried to do this, i found that, we need to activate a standard variant for the transaction, which inturn will be default for all these roles. S how will i specify different Transaction variant for diff roles...
Please help..
In the below link i have seen a solution where i need to login into each users profile and set it.
link: [Variant Groups;
Thanks,
Jithin

The way you explain is strange, I don't understand. You can't assign manually a variant group to a transaction variant, this is done automatically based on the names, maybe you make confusion with assignment between variant group and user?
A little example:
Say we have : ZG1 for group 1, and ZG2 for group 2. Transaction is ZT.
Say user is assigned to group ZG1 by default, and also ZG2 (he may switch to ZG2 using the transaction I mentioned above)
When user runs ZT transaction, SAP uses automatically ZG1ZT transaction variant (the standard variant is ignored when a transaction variant is found based on variant group). If the user switches to ZG2 variant group, SAP uses automatically ZG2ZT transaction variant.
If you activate a standard variant, this will taken into account for users which don't have a variant group assigned, or those which transaction variant doesn't exist for variant group + transaction code.
If it doesn't work as I said, maybe there is a bug, check SAP notes...

How can I have sms message delivery for IPhone

Check to see if there is a 3rd party app that provides it. Also, check with your carrier. If you are in the US, this is not an important thing, and most of the carriers do not provide delivery for SMS. If your from outside the US, see if the carrier supports it and what needs to be done to get it.
