Figure 5- 7. SNMP Group Table Display
To add a new entry to the switch’s SNMP Group Table, click the Add button in the upper left-
hand corner of the
SNMP Group Table
page.
This will open the
SNMP Group Table
Configuration
page, as shown below.
Figure 5- 8. SNMP Group Table Configuration
The following parameters can set:
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
SNMPv1
– Specifies that SNMP version 1 will be used.

134
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
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 Configuration
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.

The following parameters can set:
Parameter
Description
Community Name
Type an alphanumeric string of up to 33 characters that is used to identify
members of an SNMP community.
This string is used like a password to
give remote SNMP managers access to MIB objects in the switch’s
SNMP agent.
View Name
Type an alphanumeric string of up to 32 characters that is used to identify
the group of MIB objects that a remote SNMP manager is allowed to
access on the switch. The view name must exist in the SNMP View Table.
Access Right
read_only
Specifies that SNMP community members using the
community string created with this command can only read the contents
of the MIBs on the switch.
read_write
Specifies that SNMP community members using the
community string created with this command can read from and write to
the contents of the MIBs on the switch.
SNMP Host Table
Use the
SNMP Host Table
to set up SNMP trap recipients.
Open the
SNMP Manager
folder, and click on the
SNMP Host Table
link.
This will open
the
SNMP Host Table
page, as shown below.
To delete an existing
SNMP Host Table
entry, click the corresponding
X
icon under the
Delete
heading.
To display the current settings for an existing
SNMP Group Table
entry, click the blue link
for the entry under the
Host IP Address
heading.

To add a new entry to the switch’s
SNMP Group Table
, click the
Add
button in the upper
left-hand corner of the
SNMP Host Table
page.
This will open the
SNMP Host Table
Configuration
page, as shown below.

Figure 5- 11. SNMP Host Table Configuration
The following parameters can set:
Parameter
Description
IP Address
Type the IP address of the remote management station that will serve as
the SNMP host for the switch.
SNMP Version
V1
– To specifies that SNMP version 1 will be used.
V2
– To specify that SNMP version 2 will be used.
V3
– To specify that the SNMP version 3 will be used.
Community String or
SNMP V3 User Name
Type in the community string or SNMP V3 user name as appropriate.
SNMP Engine ID
The Engine ID is a unique identifier used for SNMP V3 implementations. This is an
alphanumeric string used to identify the SNMP engine on the switch.
To display the switch’s SNMP Engine ID, open the
SNMP Manager
folder, and click on the
SNMP Engine ID
link.
This will open the
SNMP Engine ID Configuration
window, as
shown below.
Figure 5- 12. SNMP Engine ID Configuration
To change the
Engine ID
, type the new
Engine ID
in the space provided and click the
Apply
button.
