Banner word "Username" preventing NCM connecting to devices

teckers.t over 7 years ago

Hi,

I have recently started working for a large retail company who have given me the task of configuring Orion to manage all of their Cisco devices. I have hit a problem that is causing a major headache. Each switch has an authentication banner configured which contains the following words:

Please Enter you Username and Password:

(Yes I know there is a typo but it was done by a predecessor)

I have configured NCM to use a set of credentials to connect to each device via SSH for backing up configs etc but NCM will not connect to devices with this banner. This does seem to be a well known issue as you can see in this thread from 2009 Device login issues but my issue is I have 4000 switches with this banner and no way of doing a bulk change on them apart from through Solarwinds that will not connect to them via ssh!

Is there a way around this so NCM ignores the banner or is there a way of changing the banner on all my switches via snmp (I do have a RW snmp string configured) in NCM?

Any chance you could trial or buy Engineer's Toolset? Then you could make use of the RW string.

Didn't think of that! Good idea, thanks d09h I will give the trial version a go.

Got the engineers toolset up and running but I cannot see an app that will allow bulk changes via snmp? The Config Upload app only allows access to one device at a time...

Hmmm...it's been a while since I've used it (probably 7 years by now). I don't recall ever doing changes like that in bulk when I used it. Perhaps post your issue here: Engineer's Toolset
I have foggy memories of using functionality within SecureCRT for bulk changes way back before I had ever used NCM. Some cool automation can be done that way--but as you said you have no vty access. Of course I would be remiss not to extoll the virtues of NCM and Toolset. Sorry SolarWinds.
Seems like you will have to choose between some fancy scripting to make changes via SNMP RW or alternatively get really repetitive with Toolset.
If I had SecureCRT, I would use some of these options...like SendCommandsToTabs.py: SecureCRT Python Scripting Examples. But without CLI access, I suppose that would be pointless. Sorry, just realized that doesn't help in your use case.

I have raised a ticket with Solarwinds. Will see what they come back with. Thanks for your response.
