Using SNMP

Working with SNMP Traps

The SNMP agent in the switch has the ability to send traps to the management station. It is not required
that the management station request them. Traps are messages alerting the SNMP manager to a condition
on the network. A trap message is sent through a PDU issued from the switch's network management
agent. It is sent to alert the management station to some event or condition on the switch.
Traps can indicate improper user authentication, restarts, the loss of a connection, or other significant
events. You can configure the switch so that traps are forwarded to or suppressed from transmission to the
management station under different circumstances. A trap informs the management station when the
switch configuration is saved using CLI/SNMP/WEB.

Trap Filtering

You can filter SNMP traps in at least two ways. You can filter traps by limiting user access to trap
families or you can filter according to individual traps.

Filtering by Trap Families

Access to SNMP traps can be restricted by withholding access privileges for user accounts to certain
command families or domains. (Designation of particular command families for user access is sometimes
referred to as partition management.)
SNMP traps are divided into functional families as shown in the
page 3-10. These families correspond to switch CLI command families. When read-only privileges for a
user account are restricted for a command family, that user account is also restricted from reading traps
associated with that family.
Procedures for filtering traps according to command families can be found in the Quick Steps for
"Filtering by Trap Families" on page

Filtering By Individual Trap

You can configure the switch to filter out individual traps by using the
command allows you to suppress specified traps from the management station. The following information
is needed to suppress specific traps:
• The IP address of the SNMP management station that will receive the traps.
• The ID number of the individual traps to be suppressed.
Procedures for filtering individual traps can be found in the Quick Steps for
