SNMP Version 1

SNMP Version 3

© Copyright Lenovo 2015
Lenovo N/OS provides Simple Network Management Protocol (SNMP) version 1,
version 2 and version 3 support for access through any network management
software, such as Lenovo Director.
To access the SNMP agent on the CN4093, the read and write community strings
on the SNMP manager should be configured to match those on the switch.
The read and write community strings on the switch can be changed using the
following commands:
CN 4093(config)# snmp-server read-community <1-32 characters>
-and-
CN 4093(config)# snmp-server write-community <1-32 characters>
The SNMP manager should be able to reach the management interface or any one
of the IP interfaces on the switch.
For the SNMP manager to receive the SNMPv1 traps sent out by the SNMP agent
on the switch, configure the trap host on the switch with the following command:
CN 4093(config)# snmp-server trap-source <trap source IP interface>
CN 4093(config)# snmp-server host <IPv4 address> <trap host community string>
Note: You can use a loopback interface to set the source IP address for SNMP
traps. Use the following command to apply a configured loopback interface:
snmp-server trap-source loopback
CN 4093(config)#
SNMP version 3 (SNMPv3) is an enhanced version of the Simple Network
Management Protocol, approved by the Internet Engineering Steering Group in
March, 2002. SNMPv3 contains additional security and authentication features that
provide data origin authentication, data integrity checks, timeliness indicators and
encryption to protect against threats such as masquerade, modification of
information, message stream modification and disclosure.
SNMPv3 allows clients to query the MIBs securely.
SNMPv3 configuration is managed using the following command path:
CN 4093(config)# snmp-server ?
For more information on SNMP MIBs and the commands used to configure SNMP
on the switch, see the Lenovo N/OS 8.3 Command Reference.
