update access point

Montana_Net · July 11, 2016, 8:24pm

is it possible to update the access point login and password via snmp?

newkirk · July 11, 2016, 8:46pm

Yes.

You should be able to write 1.3.6.1.4.1.161.19.3.3.2.45 and 1.3.6.1.4.1.161.19.3.3.2.46, which IIRC .45 tells it what username and .46 sets the password.

Check the docs/MIB to be sure. There is another UserPswd field that is read-only, and another set of user/pass related fields in the newer MIBs at least.

strange, i am not getting a response from my snmpwalk , its saying there is no shuch instance in this MIB.

here is the device i am trying to access

Device Type : 5.7GHz - Access Point Board Type : P11 C40 Software Version : CANOPY 13.4 AP-DES

Thanks for your help, this is my 2nd attempt at gathering / modifiying data via snmp, so kind of winging it :)

maybe i have the wrong mib loaded , not sure what one i should be using :(

The MIB won't matter if you hit the OID directly via numbers.

Try an snmpwalk of 1.3.6.1.4.1.161.19.3.3.2 - when I fire that off against a PMP450i 900MHz P13 AP running 14.1.2 I get:

The results like "whispBoxConfig.254.0" are where the MIB that snmpwalk is using is from an older firmware that lacked that field, so it doesn't have a name/info on that field in the MIB - but it will still display it.

am not getting any response

just tried on a 450i running 14.1.1

i have another OID for sm count that i have used for testing

Request Failed: Get Response PDU received from 172.31.11.138 Error Indication in response: There is no such object in this MIB. Object ID: .1.3.6.1.4.1.161.19.3.3.2 NULLOBJ: NULL (this does not)

Sent GET request to 172.31.11.138 : 161
.1.3.6.1.4.1.161.19.3.1.7.1.0
30

(see this OID works fine)

Sent GET request to 172.31.11.138 : 161
Request Failed: Get Response PDU received from 172.31.11.138 Error Indication in response: There is no such object in this MIB. Object ID: .1.3.6.1.4.1.161.19.3.3.2 NULLOBJ: NULL

Montana_Net · July 12, 2016, 3:20pm

<?php
$session = new SNMP(SNMP::VERSION_2c, '172.31.11.138', 'string');
var_dump(@$session->get('.1.3.6.1.4.1.161.19.3.3.2'));
var_dump($session->getError());
?>

bool(false) string(99) "Error in packet at 'iso.3.6.1.4.1.161.19.3.3.2': No Such Object available on this agent at this OID"

not sure why this is not returning anything. according to your results i should be getting a reply

I think this might be the problem here - 1.3.6.1.4.1.191.19.3.3.2 is NOT something you can 'GET', you need to 'WALK' it. GET will only work if there is a single value being retrieved. (I assume that 'string' is actually the appropriate community string configured on your radios...)
