HW IKEV2/IPSEC algorithms supported in ISR G2 and G3 (43xx) new

Hello

I'm updating crypto for all our vpn routers.

I'm picking the most documented algorithms in the NextGen encryption Guide

http://www.Cisco.com/Web/about/security/intelligence/nextgen_crypto.html

I would use the curve elliptical vs RSA when possible

We use ASR1002x as hubs of line head and a mixture of 881, 891, 891F, 3925 (with the ISM code), 3945E and 4331

The guide above warns some routers cannot handle some of the algorithms in HW, but provides no details.

Does anyone have info on the algorithms to avoid on the 891 ISRG2, 3925, 3945E?

My current config on the 891 s is

proposal of ikev2 crypto flaw
encryption aes-cbc-256
integrity sha512
Group 14

rypto ikev2 profile test1

match fvrf INET
match certificate map1
identity local dn
sharing front of remote authentication
authentication remote ecdsa-sig
authentication local ecdsa-sig
door-key local xxxx

Crypto ipsec transform-set esp - aes 256 esp-sha-hmac TRANSFORM1

Crypto ipsec profile xxxxxx
game of transformation-TRANSFORM1
group14 Set pfs

Thanks in advance

    Try creating a new profile as a test to check whether your profile is the source of the problems.

    See "basic troubleshooting: a new profile:

    There may be extensions and plugins installed by default in a new profile, so check that in "tools > Modules > Extensions & Plugins" in case there are still problems.

    If the new profile works then you can transfer files from the old profile to the new profile, but make sure not to copy corrupted files.

  • What is the largest hard drive or the RAID supported by El Capitan and Yosemite?

    What is the largest hard drive or the RAID supported by El Capitan and Yosemite?  Also, WHERE can I find this specification?  Drobo claims that 16 TB is the largest external RAID supported and I do not.

    FYI............ 2 UPDATES since I posted this question:

    "1. Drobo has updated their FIRMWARE to allow now to 'beyond' 64 power to RAID".  Thus, their original 16 TB limit has now been replaced by their new limit of 64 to.  Also note that when you use a Drobo, Apple Mac OS does correctly shows space 'Drive' and the 'free space', if the Drobo 16TB exceeds the size; but the Application DashBoard of Drobo displays the correct numbers.  For example, my Drobo 5 d contains 5, 8 TB disks, for a total size beyond 40 to RAID (theoretically, since most of us should know, now, that the ACTUAL SIZE IS SLIGHTLY SMALLER than THE THEORETICAL SIZE).  AVAILABLE FOR USE ACTUAL SIZE IS ONLY 28.9 TB.  Thus, 40-28, 9 = 11.1 TB gets used in place for the PROTECTION of RAID beyond and the difference between REAL SPACE and SPACE THEORY.  It IS NORMAL because any RAID 5 device always uses about 1 size of hard drive for its Protection.  So, knowing this, the DeskTop icon showing 28.9 TB disk space and free space as everything that is not yet used.  However, instead, the Mac OS shows 70,37 TB disk space and free space like 68,37 TB, which are both incorrect.  Although I'd love it if Mac OS has been magically increase my disk space, in fact, these two numbers are false.  Drobo knows this, and Apple has not, in my discussions with both.  So I hope, between the two companies, that this problem can be corrected.

    2. after many hours on the phone with Apple Support, through no less than 6 people including 2 senior advisers, NONE OF THEM COULD ANSWER MY QUESTION ON CE WHO IS MAXIMUM ALLOWED HARD DRIVE or RAID SPACE AUTHORIZED BY Yosemite and El Capitan.  For me, THIS IMPORTANT FACT SHOULD SIMPLY BE LISTED IN THE OS SPECIFICATION TECHNIQUE, it's quick and easy to read on the Support Site.  But Apple is the new bureaucracy, they are, I don't see what is happening any time soon.  So, be aware that, for now, HE IS No. LIMIT ON SIZE, as an Apple adviser said; but could not confirm in writing; and, IT IS AN INCORRECT DISPLAY SIZE AND FREE SPACE, if your drive is greater than an unknown 16 + TB in size.  Note that I have 3 other RAIDs that are properly in place showing that 9 TB, TB 12 and 18 to size; but I do not know how the SIZE IS IMPORTANT to ensure that the operating system display it correctly, except for my Drobo TB 40.  So, the bottom line, somewhere between to 18 and 40 to is where he goes wrong, in its display of sizes.

  • Firefox 4.0 does support Norton Identity Safe and Safe Search yet?

    Since about a month ago, Firefox 4.0 did not support Norton Identity Safe and Safe Search. At the point where you have indicated that this problem would be fixed from beginning of May. What is the current status?

    Thank you.

    Symantec made an update for their Add-ons to work in Firefox 4, but they only reported them as being compatible with Firefox 4.0, they need to update them to let their work in Firefox 4.0.1.

  • If I do not support until my MBP before installing a new hard drive...

    Very quick question:

    If I don't support my hard drive before installing a new hard drive, SSD, the MBP (early 2011) "know" download all the OS X software appropriate and that sort of thing? I guess my question is: is the part of the hard drive of the same hard drive recovery? Or on a separate physical disk.

    I don't have a time machine, and it would probably be easier to start from scratch.

    Thank you!

    If your computer comes with 10.6.8 or earlier and did not have its updated firmware updated to use Internet Apple system recovery, it is only on the internal drive. Otherwise, separate recovery methods are in the firmware and the drive internal.

  • CD/DVD drive, it is not supported by Windows XP and Bios

    I bought a new Mat * un Panasonic cd/dvd player.
    It only works on Windows 2000, it is not supported by Windows XP and Bios, so I can't start with.

    Could you please provide some information about yourself (name) for laptop?
    Did you buy this player or that player supplied with the notebook?

    If the player is not berecognised by the BIOS, then in my opinion, the drive supports bad master / slave / parameters c - salt.
    You should know that not all drives are compatible.

    Cannot change settings as the dose of disc supports not no rider, but only the firmware.

    My iPhone 4 stopped working yesterday, it frustrated me because I just a call, I intended to take it to get it fixed, but my sister advised I check the support of the community and guess what? It worked! Am so excited, I followed the instructions of the Mac, I pressed the Start button and the button operation at the same time and the magic took place, am so so excited. THANK YOU MAC!

    Glad that your phone is working again.

    What you were doing by pressing the button home and sleep for 10 seconds, until the Apple logo came back, is called "force restart '.

    You won't lose data by doing this, but it can cure a few glitches. It is usually the last thing to try before you restore the phone to factory again or visit an Apple Retail Store or Apple authorized service provider, where your phone does not at all.

    I followed the instructions from HP for 4 weeks. Nowhere!

    Hello

    "HP support have tried everything and gave up now."

    If HP has renounced their product, we can not offer much hope.

    It's their hardware and their software that runs their product.

    I suggest that you try their Support Forums, as it appears from their support of the unscrupulous company.

  • HP 15-ab029tx: UPDATE: HP Support fixed keyboard problem giving Me a new

    Original problem:

    Playing some games like need for speed or any game, Assassins Creed, counter-strike, Spiderman with WASD controls. After 35-45 minutes the keyboard starts to malfunction. The character starts to move randomly left direction without pressing me a key and to stop it I push on it was ' hard button.

    No problem in games, not because of synaptics Smart Sense. I've owned a lot of portable (3) to be exact, and it wasn't the problem in three others.

    Waste of time with the HP Chat Support:

    Contacted the HP Support, not one but twice. First time the Executive support uninstalled the keyboard driver and takes about half an hour to understand why the keyboard driver is not be shown in the Device Manager. After that I told him that in order for the material to be detected again, you must restart the system and then he has restarted and told me the problem is fixed and class case.

    Second time, Executive support even after say everything that I lived in the previous session started the remote session and continued and tried to update my graphics driver (I don't know why) from Device Manager. I don't know who did his Executive support because my PC has switchable graphics and HP says strictly do not update the system with switchable graphics cards manually from any where but support center HP or HP Web site.

    Finally I convinced to send someone.

    HP technician visit:

    Front panel of the laptop (keyboard + touchpad) replaced. The engineer had to remove each component of the system to reach the keyboard and replaced it finally. But then after a while when I tried to connect to my wireless router, it wouldn't even detect the connection (Yes, he was working just before the part was replaced, but not now). Not yet detected the router in the adjacent room, while all others of my device (cell phones, HP G4, tablets) can detect and connect to it.

    Which is exactly the problem:

    --> Internal Wifi Module Signal fell and it must only be connected to networks when the router or Wifi access point is close to the laptop.

    --> Hardware Wifi is fine, but the signal is removed. Before the replacement of the façade, off my all other 3 laptops and mobile phones, this system had the stronger WiFi signal.

    -->, I am aware of this problem and is not new, same problem happened to my old HP Envy 6 1002TX after that I got is fixed screen. But, as it was out of warranty, I couldn't get it repaired.

    I tried the things:
    1 reinstall the Hardwares.
    2 computer Reset.

    3 HP Support.

    I am currently connected to the internet by using the external USB WiFi card of Tenda. Here is the screenshot:

    Aftermath:

    Contact HP support, it took a lot of time to convince them that the problem is not with the software, otherwise they would have lost my time to reset the computer again. I arranged another visit of technician. We'll see if the problem is resolved.

    I searched online if anyone else had anything like this, I came across a comment:

    "Tighten the two fixing screws of a quarter turn each Wifi card in place. Guess he did not rest properly.

    This is the place where I got this: http://www.eightforums.com/network-sharing/22767-wifi-signal-strength-dropped-2-5-bars-2.html

    I reset the system again and packed until everything is fixed.

    A few comments:

    How you can recruit these people in the technical team that may not know yet what the problem is. He saw this thing through remote assistance that remained adamant that it is a software problem and asked me to give. I already told him that the system has already been reset and I tried to reinstall the drivers, but he wasted both of our time. If I were based not so much, it would have closed the ticket already.

    I don't know why these people think customer is a fool and don't know anything. Also, in the course of the support remote he ran a few commands on cmd which were for when you can not connect to the internet, but in this case the connection has not yet detected. I don't know why they do things like these.

    No doubt HP service is great, but you lose a lot of time to prove that you are right. The last time with my laptop 1303AU G4, there was a problem, but the local service station couldn't even find where the problem was. Then I had to search on the internet about this problem and found that it was because of the faulty motherboard and he said to the HP support and finally when only 10 days of warranty was left they took the laptop and fixed.

    PS - I'm no * beep * this time. I want the laptop fixed like new. I regret already buy one of your fancy 6 1002TX model until today and I'm not going to see the same thing happen to it. repair or give my money!

    The problem is now resolved. Finally, HP sent a good technician who changed the WiFi module and the problem was solved. If HP have sent the same engineer before I would ever encounter this problem. Nevertheless, thank you very much.
