MIMIC SNMP Simulator
includes full SNMPv1, SNMPv2c and SNMPv3 functionality.
-
At this point you should have MIMIC installed, and the MIMICview GUI
running
(see details)
. If you don't have MIMICview running, please consult your license e-mail
to get it installed and running.
-
You can verify that you already have snmpv1, snmpv2c and snmpv3 enabled
in MIMIC as shown in the Help -> About Mimic... dialog in
MIMICview. It should be listed under Loaded protocols.
-
If you want to load additional optional modules, now is the time to
follow the get started page for that module, ie.
run Protocol Wizard using the Wizards -> Protocol Wizard menu in
MIMICView
(see details)
and install the module.
Configure a SNMP agent for SNMPv3
-
These SNMPv3 MIBs are already compiled in MIMIC:
- SNMP-FRAMEWORK-MIB
- SNMP-USER-BASED-SM-MIB
- SNMP-VIEW-BASED-ACM-MIB
- SNMP-USM-DH-OBJECTS-MIB
- SNMP-TARGET-MIB
- SNMP-NOTIFICATION-MIB
- SNMP-PROXY-MIB
- SNMP-COMMUNITY-MIB
- SNMP-USM-AES-MIB
-
The SNMPv3 page of the Edit->Add->Agent or Edit->Configure
menu configures SNMPv3-specific parameters for the agent instance. This
tab is only visible if you have enabled SNMPv3 for the agent in the
Advanced tab.
- Engine ID -- specifies the engine ID for the agent. It is in ASCII format by default, or hexadecimal format if it starts with \x. If left empty, it defaults to an ASCII string containing the hexadecimal value of the agent IP address.
- USM Database -- specifies a file containing the User-Based Security Model definitions, as detailed in RFC 2574.
- VACM Control Database -- specifies a file containing the View-based Access Control Model definitions, as detailed in RFC 2575.
-
These files are self-documented and editable.
Below is the default username/contextname settings:
Username with no context name:
Type User Authentication Privacy noAuthNoPriv user1 authNoPriv user2 MD5 authNoPriv user3 SHA authPriv user4 MD5 DES authPriv user5 SHA DES authPriv user6 MD5 AES authPriv user7 SHA AES Note: password for all user setting is 1234567890abcdef
Username with context names:
Type User Authentication Privacy Context noAuthNoPriv user11 context11 authNoPriv user12 MD5 context12 authNoPriv user13 SHA context13 authPriv user14 MD5 DES context14 authPriv user15 SHA DES context15 Note: password for all user setting is 1234567890abcdef
For example, if you want to add user md5des, password passw0rd, with MD5/DES, for MIMIC 21.20 and later you can use the SNMPv3 Wizard as shown in this Youtube video . Else, add one line in v3usm.conf and save the file:
md5des md5des HMAC-MD5-96 passw0rd CBC-DES passw0rd
Add two lines in v3vacm.conf and save the file:
group md5des usm md5des access md5des "" usm authPriv exact public netman none
-
For advanced setting of SNMPv3 simulation/agent in MIMIC, please follow
below instructions. This allows advanced access/modification of agent
from external management application. With this setup you can
create/delete user using SNMP commands from a management application.
-
Make sure your existing simulation include following MIBs, if not
then add missing mibs using Simulation->Devices option from MIMICView
- SNMP-COMMUNITY-MIB
- SNMP-FRAMEWORK-MIB
- SNMP-TARGET-MIB
- SNMP-USER-BASED-SM-MIB
- SNMP-VIEW-BASED-ACM-MIB
- SNMP-NOTIFICATION-MIB
-
Select the Setup SNMPv3 User Management tables option in
the Startup page of the Edit->Add->Agent or
Edit->Configure dialog.
-
Start the agent, and you will notice that all mib data related to v3
configuration will already be populated automatically and you are ready
to access/modify agent from external management application using
username/contextname settings on the agents.
