openmanage network manager does not login to switch

i am using openmanage network manager 5.1 to manage PowerConnect 7048 switches.

i am able to manage/monitor the switches using SNMP without issues.

however when i use telnet/ssh it keeps throwing errors saying "1 did not respond to authentication. please click here for list of devices that did not respond. will attempt to manage these as default devices." 

the document however doesnt say what should be written in the enable ID field.

    If i want to use telnet/ssh for a PC7048 switch, do i have to club it with SNMP? will just using telnet not work.

    I assigned level 15 to a user admin

    So do i still have to enter something in the

    Enable ID

    Enable Password

    sections?

    i am able to telnet into the switch from command prompt and from web browser. but simply cannot make this OMNM work with telnet

    I'm having the same problem, what did you change on the SSH configuration of the switch to get this working?

    Regards

    Same problem here, it's a pity that it lacks a good manual and a Dell technical who knows how to use it.

    Hello All,

    I am in the same situation. PowerConnect 7048 - I can Telnet, SSH and manage via Web interface but no joy on adding it to OpenManage network. Get error..

    Did not respond to authentication. I have tried all the PDF's in terms of configuration but no joy. Anyone else have ideas ?

    All,

    The documentation on this software is terrible. Note that by reading a variety of posts, it now makes sense how to allow discovery.

    1. Make sure SNMP is configured properly on both the switch and OMNM (or OME). If SNMP is not configured properly, discovery will not happen.

    2. Configure SSH authentication methods, users, etc. on the switch.

    3. When doing discovery set SNMP as the first method and then SSH as the second method.

    After doing the above an "Inspect" was success and then discovery worked fine.

    I hope that helps!

    I agree.  This product is unecessarily cumbersome.  We use SolarWinds and I can discover multiple devices in 1/4 of the time it has taken me to test this.  That being said if I can get this working I might keep it running for the sake of getting additiional performance data from my F10 switches.

    I'm running this on SVR2012.

    When I attempt to discover the switch it says it can't login.  I'm discovering with SNMP and Telnet.  We don't have SSH enabled on the switches.  Perhaps it doesn't work without SSH.

    At one point I wondered if it required the OS clients in order to login, so I added the following features:

    SNMP

    Telnet Client

    TFTP Client

    Didn't fix the problem, but I still need to reboot.  Would like to get this working but not willing to spend too much more time doing so.  Any hints is appreciated.  Network discovery with valid SNMP should be piece of cake.  If this product isn't able to do that there is a design problem.
