Monitoring Packet Loss
It is possible to monitor packet loss by configuring the generation of SNMP traps when packet loss exceeds
a specified threshold. The configuration described in this task enables the creation of entries in the MIB tables
of the EVENT-MIB. This can then be monitored for packet loss using SNMP GET operations.
Before You Begin
Note
Entries created in the EVENT-MIB MIB tables using the configuration described in this task cannot be
altered using an SNMP SET.
Entries to the EVENT-MIB MIB tables created using an SNMP SET cannot be altered using the
configuration described in this task.

Purpose
Generates SNMP EVENT-MIB traps for the interface when the packet loss exceeds
the specified thresholds. Up to 100 interfaces can be monitored.
falling lower-threshold —Specifies the lower threshold. When packet loss between
two intervals falls below this threshold and an mteTriggerRising trap was generated
previously, a SNMP mteTriggerFalling trap is generated. This trap is not generated
until the packet loss exceeds the upper threshold and then falls back below the
lower threshold.
interval sampling-interval —Specifies how often packet loss statistics are polled.
This is a value between 5 and 1440 minutes, in multiples of 5.
rising upper-threshold —Specifies the upper threshold. When packet loss between
two intervals increases above this threshold, an SNMP mteTriggreRising trap is
Implementing SNMP
Purpose
Displays the SNMP context mapping table.
