Hi Guys,
Atttaching new definition files for Cisco ASA5500 and ASA5500-X Nextgen Firewall Series.
These include tracking of active/standby and WebVPN users and all the other useful information for the ASA.

Note! SNMP Read from a Cisco ASA Context is limited and will in some instances for boot image, serial and modules leave you with no data unless you read the system/admin context.

These definition files are tested in production use (ASA5585 and ASA5512-X) , with both single/routed and muliple context modes on ASA5500 and ASA5500-X setups.

See images for examples.

Other / I've made A SNMP Location Generator (2.0.1) for use with NeDi
« on: February 24, 2014, 01:41:44 PM »
Hi,
I've been using NeDi activly since 2009, and based on this wonderful experience
I have made a simple utility using Google Maps for creating consistent and informational SNMP Location string's
for use with SNMP enabled equipment and monitoring solutions like NeDi.

I hope the NeDi community find the utility useful, and come with suggestions for both new features and improvements ;D

SNMP Location Generator is located at http://snmplg.kvatn.net/

Cheers,
Kevin

Hi, I want to say thanks for making such awesome network discovery and monitoring software.

Now over to the issues I found related to access point discovery via WLC and switch (CDP).

1. I found that using the -F flag for fqdn will result in Access Points data found on both WLC and via switch (CDP) will result in two devices being discovered and there is no merge of data.
I've tried to AP name with domain, eg. apname.domain.net to get this to work, but this also results in the access points data not to merge correctly.
This is due to when the AP is discovered via CDP it comes up as apname.domain.net.domain.net (domain is added twice), this is "logical" as CDP name disovered is hostname and thus "missing" the fqdn and NeDi adds this from the switch data.
NOTE! AP discovery data will merge and give the correct result if not using -F.

2. To get AP SNMP data to be correct, eg. SNMP location is from AP instead of CDP switch SNMP location, I first have to run switch discovery first and then run WLC discovery.
I'll do some more research into this.

3. Ethernet/LAN interface data (IP, MAC address, etc.) not added during WLC discovery proccess, this would be useful as not all APs are connected to a CDP switch to get Ethernet data from and merge with. Eg. I could monitor AP even if I dont have access to switch in remote locations.
Data is present but there seems to be no code handeling Ethernet correctly in inc/libsnmp.pm in function WLCFwd().

See attached images and logs from NeDi and snmpwalk for details.

-Update added images.

Hi, I get a Invalid input detected at ^ no matter what command I send to Cisco switches.
Anyone have any idea what could be wrong?

LAN/Switching / Feature request: Stack monitoring/Error detection.
« on: February 07, 2012, 10:53:31 AM »
Hi,
I would love to be able to detect and get alarms for stack switches that gets removed or dies on Cisco devices.

Code: [Select]
IF StackSub-St3-1 went down

IF StackSub-St3-2 went down

If both stacksub interfaces go down, create alarm.
Could also be combined with next line.

Code: [Select]
Module WS-C3750X-24 SN:XXXXXXXXXXX in slot 3 was changed to a WS-C3750X-24 - Provisioned with SN:<< Provisioned SN: field, is now blank.


Code: [Select]
#sh switch
Switch/Stack Mac Address : xxxx.xxxx.xxxx
                                           H/W   Current
Switch#  Role   Mac Address     Priority Version  State
----------------------------------------------------------
*1       Master xxxx.xxxx.xxxx     15     1       Ready
 2       Member xxxx.xxxx.xxxx     1      1       Ready
 3       Member 0000.0000.0000     0      1       Removed

When stacked switch comes back, the following is in Monitoring Events.

Code: [Select]
Module WS-C3750X-24 - Provisioned SN: in slot 3 was changed to a WS-C3750X-24 with SN:XXXXXXXXXXX<< Check Provisioned SN: field, data is filled in.

Cheers,
Kevin

Discovery / Backup of device config failes over SSH.
« on: February 12, 2010, 11:05:28 AM »
Hi, there seems to be a problem with SSH and device config backup.
In monitoring-health i get the following error message,
Config backup error: SSH:Permission denied at ./inc/libcli-netssh.pl line 388
So it seems login or executing sh run command on the Cisco devices fail.
I dont think its login due to the fact that the SSH login only fails during backup, and under a device ssh login is marked as successful.

Running: Nedi 1.0.5

Anyone have an idea whats causing this?
NOTE! Backup for devices running telnet works like a charm ;)
