Reset through SNMP

Hi,

We have quite a number of 2524's that have hung since we configured SSH access. You can access the log on screen but they hang after password is entered.

A reboot fixes this temporarily, unfortunately a lot of these are in remote locations and we can only communicate with SNMP currently.

Therefore my question is; is there a way to reboot a procurve switches via SNMP?

Thanks.

Re: Reset through SNMP

Not sure about SNMP access but have you tried web/SSL?

Web UI is disabled as SSL not supported on 2524s.

Basically switch is only responding to SNMP traps right now, hence wondering if there was a way to reboot via this method.

Thanks

Re: Reset through SNMP

Ok, the OID seems to be: 1.3.6.1.4.1.11.2.14.1.3

hpicfReset

setting it to a value of '1' will give you a warm reboot, although I haven't managed to get it to work on my test switch yet.

Re: Reset through SNMP

hi,
i tested it with an 4208vl and it worked.
At least from the cli.

hpicfReset.0 -i 2
just to set it to another value
and then
hpicfReset.0 -i 1
and it rebooted.

Re: Reset through SNMP

Yes, just tried it through the cli on a 2610 running r.11.30 and the value it seems to want is '2'.

# getmib hpicfReset.0
hpicfReset.0 = 1

#setmib hpicfReset.0 -i 2
hpicfReset.0 = 2

Then the switch reboots with the current config.
I still can't seem to access that mib remotely though.

Re: Reset through SNMP


Thanks to your responses I have just managed to get this work remotely.

Using SNMPc I have set up this mib as custom tool on the right-lick menu for all switch objects. I have attached a screen shot to show settings.

Now I can right click any of the switch and give them a remote reboot. It even works on the hung ones, which I was having the original issue with.

Perfect!

Re: Reset through SNMP

Hi,

Thanks for the screenshot, that was useful! One question, how did you work out the string for the Argument? If I browse for the Mib I get something completely different (which fails to work).
I'm fairly sure it's using the latest MIB files from the HP site.

Thanks.

Re: Reset through SNMP


First I located it using mib browser under the tools menu by searching for 'hpicfReset'

Then I just browsed to that location from 'Add custom Menu' it and it worked.

Re: Reset through SNMP

In fact, if you find it on mib browser first (see screen shot); you can see how the argument is structured from the properties:

MIB|Name.0 x ---> HP-ICF-BASIC|hpicfReset.0 2

x is the variable

Hope that helps.

Re: Reset through SNMP

Thanks. I think my MIB files are in a bit of a mess so I'll try clearing out all the old ones and try again.
When you said "using mib browser under the tools menu by searching for 'hpicfReset'", I assume you meant a manual search?

Re: Reset through SNMP

In SNMPc;

1. Highlight the object you want see mibs for.
2. Click tools > mib browser
3. In the dialgouge, type in the search string
4. Click next

That's how I found it. Then just did the steps I mentioned before.
