You can set up one or more of the following types of trap filters:
Global—Filters traps by type and severity level across all trap categories
Per-category—Filters traps for a specific category by type and severity level
Host-specific—Filters traps on a specific host by type and severity level
Trap filters work as follows:
An event is posted to the SNMP agent.
1.
The system determines whether the corresponding trap category is globally enabled
2.
and whether the trap meets the minimum severity level for the trap category. If the
per-category filter is not defined for this trap, the global trap severity applies.
If the trap does not meet these criteria, the system discards the trap.
If the trap does meet these criteria, the trap goes to the trap host processor.
The trap host processor determines whether the trap category is enabled on the host
3.
and whether the trap meets the minimum severity level set for the host.
If the trap does not meet these criteria, the system discards the trap.
If the trap does meet these criteria, the trap is sent to the trap recipient.
To set up global severity filters, use the snmp-server enable traps command. To specify
the trap severity level for a particular category, use the snmp-server enable traps
per-category-trapFilters command. To set up a severity filter for a specific host, use the
snmp-server host command.
Use to enable and configure SNMP trap generation on a global basis.
Traps are unsolicited messages sent from an SNMP server (agent) to an SNMP client
(manager).
