88.13 Configure SNMP
Use this screen to configure your SNMP settings. Simple Network Management Protocol (SNMP) is an
application layer protocol used to manage and monitor TCP/IP-based devices. SNMP is used to
exchange management information between the network management system (NMS) and a network
element (NE). A manager station can manage and monitor the Switch through the network through
SNMP version 1 (SNMPv1), SNMP version 2c or SNMP version 3. The next figure illustrates an SNMP
management operation. SNMP is only available if TCP/IP is configured.
Figure 562 SNMP Management Model
An SNMP managed network consists of two main components: agents and a manager.
An agent is a management software module that resides in a managed Switch (the Switch). An agent
translates the local management information from the managed Switch into a form compatible with
SNMP. The manager is the console through which network administrators perform network management
functions. It executes applications that control and monitor managed devices.
Privilege Enter the privilege level for this user. At the time of writing, users may have a privilege level of
0, 3, 13, or 14 representing different configuration rights as shown below.
• 0 – Display basic system information.
• 3 – Display configuration or status.
• 13 – Configure features except for login accounts, SNMP user accounts, the
authentication method sequence and authorization settings, multiple logins, administrator
and enable passwords, and configuration information display.
• 14 – Configure login accounts, SNMP user accounts, the authentication method
sequence and authorization settings, multiple logins, and administrator and enable
passwords, and display configuration information.
Users can run command lines if the session’s privilege level is greater than or equal to the
command’s privilege level. The session privilege initially comes from the privilege of the login
account. For example, if the user has a privilege of 5, he or she can run commands that
requires privilege level of 5 or less but not more.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
