hi sagar
i'm not a guru but something that i know  may helpful to you.

step 1
 select net-snmp using 'make menuconfig' 
( i selected only net-snmp snmpd)

step 2
modify some source (find 'Sangsu Baek' in net-snmp-users  mailling-list).

step 3
cd to net-snmp 
make clean

step 4
create config file to romfs/etc/snmpd.conf
I attached example file, just use it !

step 5
cd to root - directory and make
if there some errors , just make again.

step 6
load & run your linux images.
exec following command in console 
# snmpd -f -c /etc/snmpd.conf&

I'm sure these will make you a happy man !

regards

Sangsu Baek

snmpd.conf (application/octet-stream, 16.1 KB)

###############################################################################
#
# EXAMPLE.conf:
#   An example configuration file for configuring the ucd-snmp snmpd agent.
#
###############################################################################
#
# This file is intended to only be an example.  If, however, you want
# to use it, it should be placed in SYSCONFDIR/share/snmp/snmpd.conf.
# When the snmpd agent starts up, this is where it will look for it.
#
# You might be interested in generating your own snmpd.conf file using
# the "snmpconf" program (perl script) instead.  It's a nice menu
# based interface to writing well commented configuration files.  Try it!
#
# Note: This file is automatically generated from EXAMPLE.conf.def.
# Do NOT read the EXAMPLE.conf.def file! Instead, after you have run
# configure & make, and then make sure you read the EXAMPLE.conf file
# instead, as it will tailor itself to your configuration.

# All lines beginning with a '#' are comments and are intended for you
# to read.  All other lines are configuration commands for the agent.

#
# PLEASE: read the snmpd.conf(5) manual page as well!
#


###############################################################################
# Access Control
###############################################################################

# YOU SHOULD CHANGE THE "COMMUNITY" TOKEN BELOW TO A NEW KEYWORD ONLY
# KNOWN AT YOUR SITE.  YOU *MUST* CHANGE THE NETWORK TOKEN BELOW TO
# SOMETHING REFLECTING YOUR LOCAL NETWORK ADDRESS SPACE.

# By far, the most common question I get about the agent is "why won't
# it work?", when really it should be "how do I configure the agent to
# allow me to access it?"
#
# By default, the agent responds to the "public" community for read
# only access, if run out of the box without any configuration file in 
# place.  The following examples show you other ways of configuring
# the agent so that you can change the community names, and give
# yourself write access as well.
#
# The following lines change the access permissions of the agent so
# that the COMMUNITY string provides read-only access to your entire
# NETWORK (EG: 10.10.10.0/24), and read/write access to only the
# localhost (127.0.0.1, not its real ipaddress).
#
# For more information, read the FAQ as well as the snmpd.conf(5)
# manual page.

####
# First, map the community name (COMMUNITY) into a security name
# (local and mynetwork, depending on where the request is coming
# from):

#       sec.name  source          community
#com2sec local     localhost       COMMUNITY
#com2sec mynetwork NETWORK/24      COMMUNITY


####
# Second, map the security names into group names:

#             	sec.model  sec.name
#group MyRWGroup	v1         local
#group MyRWGroup	v2c        local
#group MyRWGroup	usm        local
#group MyROGroup v1         mynetwork
#group MyROGroup v2c        mynetwork
#group MyROGroup usm        mynetwork
group rwGroup   v1         rwAccess
group rwGroup   v2c        rwAccess
group rwGroup   usm        rwAccess
group roGroup   v1         roAccess
group roGroup   v2c        roAccess
group roGroup   usm        roAccess

####
# Third, create a view for us to let the groups have rights to:

#           incl/excl subtree                          mask
view all    included  .1                               80

####
# Finally, grant the 2 groups access to the 1 view with different
# write permissions:

#                context sec.model sec.level match  read   write  notif
#access MyROGroup ""      any       noauth    exact  all    none   none
#access MyRWGroup ""      any       noauth    exact  all    all    none
access roGroup   ""      any       noauth    exact  all    none   none
access rwGroup   ""      any       noauth    exact  all    all    none

# System contact information
#

# It is also possible to set the sysContact and sysLocation system
# variables through the snmpd.conf file.  **PLEASE NOTE** that setting
# the value of these objects here makes these objects READ-ONLY
# (regardless of any access control settings).  Any attempt to set the
# value of an object whose value is given here will fail with an error
# status of notWritable.

#syslocation Right here, right now.
#syscontact Me <[email protected]>

# Example output of snmpwalk:
#   % snmpwalk -v 1 -c public localhost system
#   system.sysDescr.0 = "SunOS name sun4c"
#   system.sysObjectID.0 = OID: enterprises.ucdavis.ucdSnmpAgent.sunos4

# Process checks.
#
#  The following are examples of how to use the agent to check for
#  processes running on the host.  The syntax looks something like:
#
#  proc NAME [MAX=0] [MIN=0]
#
#  NAME:  the name of the process to check for.  It must match
#         exactly (ie, http will not find httpd processes).
#  MAX:   the maximum number allowed to be running.  Defaults to 0.
#  MIN:   the minimum number to be running.  Defaults to 0.

#
#  Examples:
#

#  Make sure mountd is running
proc mountd

#  Make sure there are no more than 4 ntalkds running, but 0 is ok too.
proc ntalkd 4

#  Make sure at least one sendmail, but less than or equal to 10 are running.
proc sendmail 10 1

#  A snmpwalk of the prTable would look something like this:
# 
# % snmpwalk -v 1 -c public localhost .EXTENSIBLEDOTMIB.PROCMIBNUM
# enterprises.ucdavis.procTable.prEntry.prIndex.1 = 1
# enterprises.ucdavis.procTable.prEntry.prIndex.2 = 2
# enterprises.ucdavis.procTable.prEntry.prIndex.3 = 3
# enterprises.ucdavis.procTable.prEntry.prNames.1 = "mountd"
# enterprises.ucdavis.procTable.prEntry.prNames.2 = "ntalkd"
# enterprises.ucdavis.procTable.prEntry.prNames.3 = "sendmail"
# enterprises.ucdavis.procTable.prEntry.prMin.1 = 0
# enterprises.ucdavis.procTable.prEntry.prMin.2 = 0
# enterprises.ucdavis.procTable.prEntry.prMin.3 = 1
# enterprises.ucdavis.procTable.prEntry.prMax.1 = 0
# enterprises.ucdavis.procTable.prEntry.prMax.2 = 4
# enterprises.ucdavis.procTable.prEntry.prMax.3 = 10
# enterprises.ucdavis.procTable.prEntry.prCount.1 = 0
# enterprises.ucdavis.procTable.prEntry.prCount.2 = 0
# enterprises.ucdavis.procTable.prEntry.prCount.3 = 1
# enterprises.ucdavis.procTable.prEntry.prErrorFlag.1 = 1
# enterprises.ucdavis.procTable.prEntry.prErrorFlag.2 = 0
# enterprises.ucdavis.procTable.prEntry.prErrorFlag.3 = 0
# enterprises.ucdavis.procTable.prEntry.prErrMessage.1 = "No mountd process running."
# enterprises.ucdavis.procTable.prEntry.prErrMessage.2 = ""
# enterprises.ucdavis.procTable.prEntry.prErrMessage.3 = ""
# enterprises.ucdavis.procTable.prEntry.prErrFix.1 = 0
# enterprises.ucdavis.procTable.prEntry.prErrFix.2 = 0
# enterprises.ucdavis.procTable.prEntry.prErrFix.3 = 0
#
#  Note that the errorFlag for mountd is set to 1 because one is not
#  running (in this case an rpc.mountd is, but thats not good enough),
#  and the ErrMessage tells you what's wrong.  The configuration
#  imposed in the snmpd.conf file is also shown.  
# 
#  Special Case:  When the min and max numbers are both 0, it assumes
#  you want a max of infinity and a min of 1.
#

# This alleviates the multiple line output problem found in the

# Run a shell script containing:
#
# #!/bin/sh
# echo hello world
# echo hi there
# exit 35
#
# Note:  this has been specifically commented out to prevent
# accidental security holes due to someone else on your system writing

#
# exec .EXTENSIBLEDOTMIB.50 shelltest /bin/sh /tmp/shtest

# % snmpwalk -v 1 -c public localhost .EXTENSIBLEDOTMIB.50
# enterprises.ucdavis.50.1.1 = 1

# enterprises.ucdavis.50.3.1 = "/bin/sh /tmp/shtest"
# enterprises.ucdavis.50.100.1 = 35
# enterprises.ucdavis.50.101.1 = "hello world."
# enterprises.ucdavis.50.101.2 = "hi there."
# enterprises.ucdavis.50.102.1 = 0

# Now the Output has grown to two lines, and we can see the 'hi
# there.' output as the second line from our shell script.
#
# Note that you must alter the mib.txt file to be correct if you want

# Subagent control
#

# The agent can support subagents using a number of extension mechanisms.
# From the 4.2.1 release, AgentX support is being compiled in by default.
# However, this is still experimental code, so should not be used on
# critical production systems.
#   Please see the file README.agentx for more details.
#
# If having read, marked, learnt and inwardly digested this information,
# you decide that you do wish to make use of this mechanism, simply
# uncomment the following directive.
#
#  master  agentx
#
# I repeat - this is *NOT* regarded as suitable for front-line production
# systems, though it is probably stable enough for day-to-day use.
# Probably.
#
# No refunds will be given.
