Log Events, Statistics, Status and SNMP support
A comprehensive set of log events are supported for DCP in order to alert the operator to
potential attacks or misconfigurations and to allow tuning of the DCP settings. Refer to the
NOTIFICATION-TYPE objects with “Dcp” in the names in the following MIBs for details:
• TIMETRA-CHASSIS-MIB
• TIMETRA-SAP-MIB
• TIMETRA-VRTR-MIB
The log events can also be seen in the CLI using the following show log event-control |
match Dcp command
DCP throttles the rate of DCP events to avoid event floods when multiple parallel attacks or
problems are occurring.
Many of the DCP log events can be individually enabled or disabled at the DCP policy level
(in the DCP policy config) as well as globally in the system (in log event-control).
If needed when a DCP log event indicates a SAP, and that SAP is an MSAP, the operator can
determine which subscriber(s) is/are on a specific MSAP by using the show service active-
subs command and then filtering (“| match”) on the msap string.
Statistics and status related to DCP are available both via:
•CLI
• SNMP — See various tables and objects with “Dcp” or “DCpuProt” in their name in
the TIMETRA-CHASSIS-MIB¸ TIMETRA-SECURITY-MIB, TIMETRA-SAP-MIB
and TIMETRA-VRTR-MIB
