SNMP Walk Procedure

Thank you for helping us to support new network devices in NetMRI

*** Background

By default, NetMRI gathers data from any device that
is identified as a network device (e.g., router, switch, WAP, etc)
and that supports the standard SNMP network MIBs, such as the ARP,
Switch Forwarding, interface, and route tables.   This is known
as Basic SNMP Support and allows NetMRI to support a wide range
of network devices, including those it has never seen before.

NetMRI uses another collection of SNMP MIBs to gather data that
is more vendor specific, such as CPU and memory utilization, 
neighbors, redundant peers, configuration changes and, most importantly, 
VLAN information. This is known as Full SNMP Support and is usually 
provided by vendor-specific SNMP MIBs, which means that NetMRI may need 
to be updated the first time such devices are seen in the field.

The process of supporting new platforms begins by performing an SNMP Walk 
of the platform, which pulls all of the data values that are supported by 
the device. After analyzing the walk results, Netcordia Engineers can craft 
the modifications needed to support that platform. The process usually 
only takes a couple of days and a patch can then be provided that allows 
any NetMRI unit to provide full support for that platform.

*** SNMP Walk Process

We greatly appreciate your help with this process and we've tried to make 
it as convenient as possible, based on the following steps:

1. Download the following Net-SNMP installation package to temporary 
directory on a Windows-based PC:

	http://www.netcordia.com/files/net-snmp-5.2.1-1.win32.zip (4.2MB)

If you prefer a version for another operating system, please visit
http://www.net-snmp.org/download.html for a complete selection of executable 
and source code distributions.

2. Install the Net-SNMP package on your workstation using the downloaded 
executable, placing the application in a convenient directory.

3. Launch a Command window from the Windows Start Menu (or select the "Run..." 
option in the Start Menu and execute "command") and execute the following 
command line:

	snmpwalk -v1 -c COMMUNITY IPADDRESS .1 >snmpwalk.txt

where COMMUNITY is the community string for your network devices and
IPADDRESS is the IP address of the network device being examined.
The ".1" value indicates that all of the SNMP MIB values should be
collected and written into the designated output file.
This process may take a few minutes depending on the number of
SNMP values supported by the device and the overall load on the device.

4. Attach the output text file to an email and send it to support@netcordia.com
for analysis.

If you have any problems with this procedure or would like to know more
about the process, please call Netcordia Technical Support at 410-266-6161.
