Chapter 16: KCS Client Configuration
280 Console Server & RIM Gateway User Manual
 The SNMP Service Details tab is shown by default. The SNMP Service Details tab controls aspects of the
SNMP Service including Security Level. It manages requests from external agents for Opengear status
information.
 Check the Enable the SNMP Service box to start the SNMP Service. The Service is disabled by default.
 Select either UDP or TCP for the TCP/IP Protocol. UDP is the recommended protocol and is selected by default.
TCP should only be used in special cases such as when Port Forwarding SNMP requests/responses to or from
the Opengear device is required.
 Complete the Location and Contact fields. The Location field should describe the physical location of the
Opengear and will be used in response to requests for the SNMPv2-MIB::sysLocation.0 of the device. The
Contact field refers to the person responsible for the Opengear such as the System Administrator and will be used
in response to requests as follows: SNMPv2-MIB::sysContact.0.
 Enter the Read-Only Community and Read-Write Community. This is required for SNMP v1 & v2c only. The
Read-Only Community field is used to specify the SNMPv1 or SNMPv2c community that will be allowed read-only
(GET and GETNEXT) access. This must be specified in order for both versions to become enabled. The Read-
Write Community field is used to specify the SNMPv1 or SNMPv2c community that will be allowed read-write
(GET, GETNEXT and SET) access.
 Configure SNMP v3, if required. SNMP v3 provides secure SNMP operations through the use of USM (User-
based Security Model). It offers various levels of security including user-based authentication and basic
encryption.
o The Engine ID is used to localize the SNMPv3 user. It will be automatically generated from a Network
Interface (eth0) hardware address, if left blank, or must be entered as a hex value e.g. 0x01020304.
o Specify the Security Level:
No authentication or encryption is required. This is the minimum
level of security.
Authentication will be required but encryption is not enforced. An
authentication protocol (SHA or MD5) and password will be required.
Enforces the use of encryption. This is the highest level of security and
requires an encryption protocol (DES or AES) and password in addition
to the authentication protocol and password.
o Complete the Read Only Username. Enter the read only security name. This field is mandatory and must be
completed when configuring the console server for SNMPv3.
o For a Security Level of auth, select the Auth. Protocol (SHA or MD5) and the Auth. Password. A
password of at least 8 characters is required.
o For a Security Level of priv, select the Privacy Protocol (DES or AES) and the Privacy Password. AES is
recommended as it provides stronger privacy but requires more intense calculations. A password of at least 8
characters is required.
