26.6.1 About SNMP
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

LABEL DESCRIPTION
Options Select the trap type you want to configure here.
Port This field displays a port number.

Changes in this row are copied to all the ports as soon as you make them.
Active Select this check box to enable the trap type of SNMP traps on this port. The Switch sends the
related traps received on this port to the SNMP manager.
Clear this check box to disable the sending of SNMP traps on this port.
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.
