Parameter Description
Group Name Type an alphanumeric string of up to 32 characters. This is used to identify the new
SNMP group of SNMP users.
Read View Name This name is used to specify the SNMP group created can request SNMP messages.
Write View Name Specify a SNMP group name for users that are allowed SNMP write privileges to the
Switch’s SNMP agent.
Notify View Name Specify a SNMP group name for users that can receive SNMP trap messages generated
by the Switch’s SNMP agent.
Security Model Use the pull-down menu to select the SNMP version. Select one of the following:
SNMPv1 – Specifies that SNMP version 1 will be used.
SNMPv2 – Specifies that SNMP version 2c will be used. The SNMP v2c supports both
centralized and distributed network management strategies. It includes improvements in
the Structure of Management Information (SMI) and adds some security features.
USM – (User-based Security Module) Specifies that the SNMP version 3 will be used.
SNMP v3 provides secure access to devices through a combination of authentication and
encrypting packets over the network.
Security Level Use the pull-down menu to select the SNMP version:
NoAuthNoPriv
−
Specifies that there will be no authorization and no encryption of packets
sent between the Switch and a remote SNMP manager.
AuthNoPriv
−
Specifies that authorization will be required, but there will be no encryption
of packets sent between the Switch and a remote SNMP manager.
AuthPriv
−
Specifies that authorization will be required, and that packets sent between the
Switch and a remote SNMP manger will be encrypted.
SNMP Community Table
Use this table to create an SNMP community string to define the relationship between the SNMP manager and an agent. The
community string acts like a password to permit access to the agent on the Switch. One or more of the following
characteristics can be associated with the community string:
An Access List of IP addresses of SNMP managers that are permitted to use the community string to gain access to the
Switch’s SNMP agent.
An MIB view that defines the subset of all MIB objects that will be accessible to the SNMP community.
Read/write or read-only level permission for the MIB objects accessible to the SNMP community
