Two ACS4.0 box using win- can connect with cross over cable

Hi
we have 2 ACS4.0 box, internal replication is happening between ACS1(prim) to ACS2(sec) but not ACS2 to ACS1 why?
Also I need 1 suggesion, whether we can connect 2 ACS boxes through cross cable for sync.
At present it is connected with 2 diff cores(ACS1 to core 1 & ACS2 to core2) and cores are interconnected.
What is the normal practice.
Regards
Naga

Hi Naga,
The purpose of Replication in ACS is for the Primary Server to overwrite the secondary server's settings that you have chosen.
This is by design Replication is meant to be one way and not bi-directional.
The Cisco Secure ACS Solution Engine supports the operation of only one Ethernet connector at a time. Concurrent operation of both Ethernet connectors is not supported."
To get redundancy with any ACS - you need replication setup with TWO ACS, it is not
possible to setup a NIC failover in the same chasis.

  • Mac pro - powerbook g4 - networking with cross-over cable

    I connect my powerbook to the Mac pro with a cross-over cable.
    Personal file sharing is on both computers (both Mac osx 10.4.8)
    Question 1:
    While most of the time I can make the connection work I still don't understand the logic behind it.
    Sometimes I connect and the connection works immediately, on other occasion I have to restart one of the macs or both to make it work.
    Is there another solution then restarting?
    Please enlight me on the subject.
    Question 2:
    My Macpro is connected to the internet (to a ethernet-router up the line, I can not pull another cable from the router because all the ports are busy).
    My powerbook is connected to the Macpro with the cross-over cable.
    Can I access the internet on my powerbook through the cross-over cable. I already tried the Internet Sharing on/off thing but I couldn't make it work.
    Thank you all for sharing your knowledge on the subject.

    Hello Eugene,
    Just a quick note to let you know you and others know that you do not need a cross-over Ethernet cable to connect your Mac Pro to another device. The idea of using a cross-over cable is a hold over from bygone days of Ethernet ports and products that either were before the auto-mdix or just did not implement them to save cost. Auto mdix Ethernet ports (which the Mac Pro, and every current Mac computer has) are able to detect the type of cabling/connection, and auto configure the Ethernet port for the proper connection. This mean you can use a regular Ethernet patch cable and not be concerned if it is a straight thru or cross-over style.
    As for sharing your internet connection using your Mac Pro, yes, it can be done, and the capability is included with OS X. You can find step by step instructions by accessing the Help menu in the finder and entering "sharing Internet" (without the quotes).
    However, I would suggest you just buy an inexpensive Ethernet Switch, to use to expand the number of ports available from your router, and then run a line to your other computer.

  • Use of straight through and cross over cable

    hi,
    according to icnd1, we need to use crossover cable to connect similar devices, lets say router to router or switch to swicth..
    does this really matter? I mean, what if i use straight through cable to connect one switch to another?
    thanks

    Hmm, I don't know, does it really matter whether the link between devices can be used?  (Laugh)
    As the other posters have noted, many (newer) devices now support auto MDI/MDIX, but some don't.  (Also, on devices that do, auto negotiation might be required to be enabled.)  Some older devices sometimes have "special" uplink ports or manual method to switch the port's MDI/MDIX setting, and for those, too, you can use a strait through cable.
    If none of the above, however, you'll need a cross over cable for "similar" device types, i.e. those whose tx/rx pins, on the port, are the same.
    You need a cross over cable if both sides are MDI or MDIX (i.e. the same), straight cable if both sides are different.

  • Since upgrading the IOS 8 on my IPad 2 I can longer get a full screen on my TV when connected with an HDMI cable. anything I should change in my settings? Right now my iPad is mirrored on the TV with a black box all around the edge

    Since upgrading the IOS 8 on my IPad 2 I can longer get a full screen on my TV when connected with an HDMI cable. anything I should change in my settings? Right now my iPad is mirrored on the TV with a black box all around the edge

    I have reached the same conclusion in the mean time. I have done a bit of investgation in to other grahics cards and am seeing some that show SPDIF connections from the card to the mother board. I was not familar with SPDIF but it did a little bit of sluething. It is of course a digitally enconded voice. I am guessing that in that case the mother board ( assuming it supports this hardware option) would use this output and be able to translate that digital audio to its other audio outputs. That is a lot of guessing of course. I think my "solution" might  be a whole new desktop - a rather drastic course of action! I was in the proceess of getting ready to upgrade this machine anyway with a new graphics card (which I will now return), go to Win 7, and maybe even a new digital TV reciever,  and I don't want to throw good money after bad anyway.
    Thanks for your comments

    Thanks, helped me figure out a bigger problem there was with my router's access control and all kinds of crazy numbers that needed to be changed, but I got it.
    Problem is fixed as far as I can tell!

  • IP address not being set using Win XP Pro with Airport Extreme

    Hi,
    I'd appreciate any information on this subject. I got a new Airport Extreme on Friday to replace my DLink G router. Basically is blew up. So I've got it set up and my Vista laptop is running just fine. However, my work laptop which is a Win XP Pro machine can not aquire a network address. It continually says "Aquiring Network Address" and then times out and disconnects. After a lot of looking around and checking out blogs I took a look and it seems that I cannot get an IP address. When ipconfig in cmd it shows not IP address and subnet, etc as 0.0.0.0. OKay, so I try to reboot, I've also tried release renew and still no go. I can connect with a cable to the Airport and receive an IP immediately and obviously I can get directly on the cable modem I am using with Rogers with no issue. So can anyone tell me why over the air I can't get an IP? Did I set something up with this XP Pro machine that doesn't seem to have a problem with Vista?
    Any help would be greatly appreciated...I haven't been wired and years, slightly unsettling!
    Thanks!

    Okay I got it. I couldn't get an IP address and so I found another discussion. One person said to do this:
    The "Limited or No Connectivity" indication is because the network adapter has failed to get its IP address by DHCP from the router and Windows has defaulted to allocating a "169.254" IP address.
    Try repairing the TCP/IP stack and Winsock. Open a Command Prompt window ("Start > Run", type cmd and click OK).
    To repair the TCP/IP stack, at the prompt, type...
    netsh int ip reset resetlog.txt
    ...and press Enter
    (note the spaces in the command line). The original prompt will reappear.
    To reset Winsock entries, at the prompt, type...
    netsh winsock reset catalog
    ...and press Enter
    Exit the Command Prompt window and reboot the PC.
    Well that did it! Off I go!

  • Is there a limit as to how many devices you can connect with Edge Inspect?

    Is there a limit as to how many mobile devices you can connect with Edge Inspect? 
    Also, do we need a dedicated wi fi hub for all these devices? Are there any wi fi limitations with connecting more than 20 devices and connecting to wi-fi?
    Thanks

    The free version of Edge Inspect limits you to connecting to one device concurrently. (You can certainly disconnect from that one and connect to another if you wish, but it's just one at a time.)
    If you purchase an Edge Inspect subscription, or have a paid Creative Cloud membership, then you can connect an unlimited number of devices concurrently. (Note that I have seen up to 35 connected at once.)
    For info on purchasing options, see this blog post: http://blogs.adobe.com/edgeinspect/2012/10/23/how-to-purchase-edge-inspect/
    It does not have to be a decicated wifi router, although it certainly can if that makes sense for you. For example, at my home I have a single wifi router that I always use for my laptops and video streaming devices, with my desktop computer connected to the same router on Ethernet, and I can connect my 5 tablets and 2 mobile phones to Edge Inspect on the same router with no issues.
    My router says it can support up to 250 connections at once (Ethernet + wifi); however, I have nowhere near that many devices so I could not put that to the test. I think a more reasonable limit is around 30; however, that is just based on having to share bandwidth. You might want to check what your router says is its limit.
    Just keep in mind that the more devices you have downloading data, the slower the performance will be.

    Is it possible to recover my data from iCloud backup without working wifi? I have as many other upgraded my iPhone 4S to iOS 7.0.2 with the result that the Wi-Fi or Bluetooth no longer works. However, i can connect to iTunes via cable but there is wrong version of backup.

    Answer is no.
    If you want the iCloud backup you have to have n internet connection, thus WiFi.
    The not working WiFi has happened with quite a number of users.
    It is not exactly clear what is the cause but there are suggestions to clear it up:
    Some people have had success by removing an apostrophe from the iPhone name. If your iPhone is called something like “John’s iPhone” then this might work. Go to Settings > General > About > Name and change it to something with no apostrophe.
    Some people have reported success by putting the iPhone into Airplane mode and then going to Settings > General > Reset > Reset Network Settings, but the problem may return.
    You could also try going to Settings > Control Center and disable Access on Lock Screen then turn your iPhone off and on again.
    Make sure that your router firmware is up to date.
    Try backing up your iPhone and then restoring it. Check how to factory reset an iPhone for details.
    If nothing is working for you, try contacting Apple or take your iPhone into an Apple Store.
    Succes, Lex

  • Changed to secure - can connect with mac but not pc running vista

    I changed my wrt54gs from unsecured to secure by changing the wireless > wireless security > to security mode: WPA personal, the wpa algorithms is set to TKIP, i set up a password in the shared key area and the group key is set to 3600.  I saved the changes and now i can connect with the password with a macbook pro as well as with a ipod touch but i cant connect with a laptop running windows vista.  I would get an error saying unable to connect, funny thing is though  i am connect (and it is the correct router, not a neighbors) but it says connected with limited access. I tried to run diagnostics and repair but to no avail.  Any thoughts on what to door is limited access ok?
    thanks,
    Dave 

    Try this :
    Click Start >> Control Panel >> Network and Sharing Center >> Manage Wireless Networks, here remove all the networks present and close the Window...
    Click on Connect to a Network and try to re-connect to your Network, it should ask for your Network Key/Password, enter the correct password/network key and click Connect...
    It should connect...Once you are connected you should restart the computer, it should connect to Internet...

    It would be difficult to guarentee that all wireless devices can connect to the AirPort Express Base Station (AX), so at best, your Sony Smart TV and your sister's phone SHOULD be able to connect ... as the AX is basically no different than any other manufacturers wireless router.
