Hello,
 
I imagine this question has already been answered in this forum, so I
apologize for any redundancy I may be causing here.
 
Using the VACM model in snmpd.conf, it is possible to restrict access to v1
and/or v2c community strings based on source IP address of the initiating
NMS host (the host issuing snmpwalk, snmpget, etc)
 
Is it possible to use source IP filtering for groups of SNMPv3 users?  To
provide a concrete example, what configuration is required to create
different source IP restrictions for the two groups below? Say one wants to
limit the group 'if_group' to access from 192.168.1.0/24 and 'all_group' is
to be limited to access from 192.168.2.2/32.

#      viewname     incl/excl   subtree 
view   all_view     included    .1
view   if_view      included    .1.3.6.1.2.1.2

#       groupName      securityModel securityName
group   if_group       usm           if_user
group   all_group      usm           all_user

#      group       context sec.model sec.level match  read     write  notif
access if_group    ""      usm       auth      exact  if_view   none  none
access all_group   ""      usm       priv      exact  all_view  none  none


#            username      authProto   authpassphrase   privProto
privpassphrase
createUser   if_user       SHA         12345678
createUser   all_user      SHA         12345678         AES         12345678


#      user type         username     sec.level
       rouser            if_user      auth
       rouser            all_user     priv


Thanks,

Frank
