N2000 - arp with Enhanced hash mode issues

Hello

I want to report a problem, I got after pass a set of three switches the 6.2.6.6 version N2048 to version 6.3.0.16

After the upgrade, some PC on some VLANs failed their gateway more. I found that these devices don't y mac of the bridge in their arp table. It would seem that their arp requests would be removed in the channel port connecting the N2048 to the rest of the network stack. Add a static arp entry on the affected PC has enabled them to reach their front door.

I know that there has been a bug (fixed in 6.3.15) with package falls on the port channels using the (strengthened) 7 mode. It gave me a clue and today I changed the mode of hash for 6 (IP Source/Destination and source/destination port TCP/UDP) and I removed the static arp entries, that I had created to circumvent the problem of the day before. Then I could see the bridge as a dynamic desktop entries, as it should.

It seems that there is always a with improved hash bug in 6.3.0.16. I'll be happy to send my config and / or more information on demand to help you study the problem.

Kind regards

Martin

cool, which is literally just released although there was a lot of outings lately.

See you soon

  • Switch Cisco 2960/3560 = > recovery password and default settings with the button Mode

    Hi Experts,

    I have some confusion with the button Mode with cisco 2960/3560 switches.

    I read on many forums and articles, but where things are not clear.

    a place given 3 seconds and somewhere is given 7 or 10 seconds.

    Qus1), what is the exact time to press/hold Mode button to perform two following tasks:

    A. password recovery (according to my knowledge 3 sec) good or bad?

    Configuration of the switch (start + run) would be safe

    After the recovery of password? Yes or no

    B. factory default (according to my knowledge 10 dry) good or bad?

    I'm afraid, because if I press mode button more than 3 seconds, then

    It will delete any configuration of cisco switch. Yes or no

    Qus2) I want to recover the catalyst 2960/3560 switch password without

    Start/run configuration to lose. That is my main concern.

    Please tell me how to do this, what will be the time keeping Mode buttom

    in a few seconds?

    Can I improved modes related between two areas of distinct vSphere?

    No, Enhanced Linked Mode requires that all PSCS in the same domain and replication. Two distinct areas of vSphere with no way to replicate the new APIs that provide ELM may not display the content of these two areas.

  • Maybe it's to rewrite the BIOS with crisis recovery mode?

    Hey everybody,

    my laptop 'freezes' during BIOS 'PHOENIX' updated 2 years ago.
    SERVICE told to change the motherboard, the price as new pc, so I bought new laptop.

    I keep looking at the toshiba forum always, so I read a lot of information on the MODE of RECOVERY from CRISIS.
    so I tried to check my laptop died after 2 years.

    My satellite M100 starts in crisis recovery mode Fn + B.
    my laptop starts up to CRISIS MODE, but do not read the USB STICK
    I did the flash with the CRISDISK 1.0.0.4 USB key program, but I'm not sure I did it way right!

    My question is:
    is it really possible to REWRITE the bios with crisis recovery mode, where I can read more information on how to do it.

    I want back my M100 :)))

    Hey,.

    As Akuma writes that you should try a USB FDD instead a USB key. Key USB is supported only on new models of laptops, but as far as I know USB FDD will be always supported.

    In any case, just for your information: you should know what you're doing. It is a delicate and risky procedure and in the worst cases you might destroy the whole ROM module but if you already have a new laptop I think that it s a problem for you. ;)

    The same installation works fine on HP with Windows 7, i.e. copy of VM for HP Quality Center is ok.

    Thanks in advance for your help.

    Usually, this is caused by outdated or incompatible graphics drivers on your host.  I expect that the latest drivers for your integrated Intel HD Graphics 4000 would be probably already delivered through Windows Update, however.  Could be interesting to see if there is an optional update in your Windows Update list to get a new graphics driver.

    Otherwise, you can try the problem by disabling 3D graphic acceleration: from the VM menu, select settings..., and then in the list of material , choose display.  Clear (uncheck) the box 3D graphic acceleration .

    I hope this helps!

  • Updated with the hash values column

    Hi all

    I have a requirement to add a column to a table and fill it with the hash values. The table contains an xml column and hash value of this column need to be filled to newly added column. I think that the ora_hash function will not support the xml type column. Just tested with the following script and it works.

    update TBL_COMPONENT_XSL set hash_val = ora_hash((SELECT TCX.COMPONENT_XSL.getStringVal() FROM TBL_COMPONENT_XSL TCX where rownum =1));
    

    can you please suggest me how to fill the column with the hash values.

    HASH_VAL is the newly added column.

    Thank you

    What happens if you try with:

    update of TCX TBL_COMPONENT_XSL set hash_val = ora_hash (TCX.COMPONENT_XSL.getStringVal ());

    update of TCX TBL_COMPONENT_XSL set hash_val = ora_hash (TCX.COMPONENT_XSL.getClobVal ());

  • Limitations of architecture with replication of VM with physical RDM Mode

    What are the Limitations of Architecture with replication of VM connected with physical RDM Mode in vsphere replication. Why VMware does not support this?

    I will add some colors to the response of GS. A particular interest with regard to the physical path RDM (pRDM) works, summarize these two chips of the article:

    • Physical mode specifies minimal virtualization SCSI of the mapped device, allowing greater flexibility for SAN management software.
    • VMkernel passes all SCSI commands to the device, with one exception - the REPORT LUNS command is virtualized, so that the VMkernel can isolate the LUN to the virtual machine owner. Otherwise, all the physical characteristics of the underlying hardware are exposed.

    There is an integrated in vSphere vSphere (RV) replication agent that has several functions. In particular, she keeps track of the Scriptures to the virtual machine. When a replication cycle occurs, the changed data is replicated to the target location. The VR agent should be able to 'see' These Scriptures to follow. Given that the physical mode all SCSI commands directly to the device, the VR agent is unable to follow these changes for replication.

    Hi people

    Can we did single sign on 2 OAM with two security mode different instances. An open mode and another in Simple mode.

    Both are connected to the same LDAP for user data.

    Thank you very much!

    I think it's technically "unsupported" but I can tell you that he used to work.

    The technique was to install the server in single mode components and then change the mode back to OPEN via the admin UI on component profile but not to reconfigure the mode on the installed component.

    When you have a server to identity and then telnet-ed at the port, it would open & smpl. The AAA server does not provide the same comments, but a few simple tests will tell you if it works.

    Yet once again, blend modes is explicitly warned against. Depends on your tolerance for this sort of thing.

    Let us know if it works for you.

  • Issue of ultra endurance with some settings Mode

    Hey all,.

    Just got my z3c a few days ago, and I love so far. I noticed something weird with USM, however. I was turn on at night when I go to bed so I lose only a small amount of battery life, but the next day all my preferences seem to have been reset. I noticed this because I use a Gear Live to work, but I don't get notifications and have to go activate the watch notifications in app Android wear each time. I guess that this is not something that works as expected? Anyone have any ideas?

    Sorry to hear that you are having problems with Ultra endurance.

    Unfortunately, with the current software, Ultra endurance can reset notification app preferences. This will be fixed in a next update.
