How stable are Cisco IOS OIDs for querying data with SNMP across different model devices?

I'm querying a bunch of information from cisco switches using SNMP. For instance, I'm pulling information on neighbors detected using CDP by doing an snmpwalk on .1.3.6.1.4.1.9.9.23 Can I use this OID across different cisco models? What pitfalls should I be aware of? To me, I'm a little uneasy about using numeric OIDs - it seems like...

SNMP SET with ACL and Set Community Name

Hi All, I need to perform a SNMP Set operation in a printer in the network which as an Access Control List configured (ACL) and my host's IP Address is not in the ACL table. I'm getting a strange behavior: When I have a SNMPv1 Set community name configured, I am ONLY able to perform a SNMP Set if my host ip is in the ACL table. If there...

What is the best SNMP implementation for Python?

I'm doing some GUI prototyping with Python for an SNMP application. Looking around there seem to be a number of python libraries I could use. As I'm prototyping I value a nice clean easy API over speed and preferably a commonly packaged library. Obviously the package should be open source. So far I've been looking PySNMP, Twisted-Snmp, p...

What is the best open source SNMP monitoring tool?

I am currently working on software that must emit SNMP traps for SNMP versions 1 & 2 and possibly v3 in the future. I have downloaded several and found them to be either too complex or too simplistic. All I want is to view traps and analyze the data structures within them, and the ability to import my custom MIB's. The best I have found ...

What are some good resources for understanding SNMP MIBs?

I know a little about SNMP, but not enough. I need to develop an application that can read standard SNMP MIBs and read/write the various properties. The network end is no problem, but the actual MIBs and exactly what they may contain is something of a black art to me. I believe I should be able to use LIBSMI to 'parse' the MIBs, but I d...

Managing Cisco programatically; Telnet vs SNMP?

I was recently approached by a network-engineer, co-worker who would like to offload his minor network admin duties to a junior-level helpdesk tech. The specific location in need of management acts as an ISP for tenants on its single-site property, so there's a lot of small adjustments being made on a daily basis. I am thinking it wou...

SNMP payload address translation

I'm using iptables under linux to NAT SNMP traffic. Some of the SNMP packets have VARBINDs that contain the (real) IP addresses of the devices that generated them. This confuses standard management tools, which need to see the NATted addresses in the VARBINDs. So I need to translate the addresses in the payload in addition to those in...

I'm operating a neighbourhood WIFI network in a rural environment.

Most of this information is exposed via SNMP by my routers and access points, so SNMP support is required. Additiona...

WinSNMP v1traps

I'm using WinSNMP in c++ to send snmp traps. For backwards compatibility I’m required to send v1 snmp traps. WinSNMP works with v2 traps but is capable of converting those v2 traps to v1 when sending the trap. I use SnmpSetTranslateMode(SNMPAPI_UNTRANSLATED_V1) in order to do that. I also added the sysUpTime oid (1.3.6.1.2.1.1.3.0), the ...

Updating an existing trap parameters (objects) and partially sending parameters in a trap

We have created a list of traps (notification) that our application is exposing and described it in a MIB file. Today we came into a situation that we need to update the MIB and add additional (OPTIONAL) parameter to the trap (update the Objects).

FTP and SNMP Support in .NET

Hello All, I've been perplexed over a .NET dilemma for the past couple months. I can't seem to find any support for standard protocols in the framework.

Dumb Linux SNMP question

I'm running Ubuntu and have snmpd running. I can do an snmpwalk: snmpwalk -c public -v 1 localhost .1 and I get back about 20 values (SNMPv2-MIB -- mostly system description/name/uptime stuff). Where are the memory, disk and network values? I've tried querying specific OIDs that I found Googling and they're not found. I assume I ...
