Supported MIBs
The Cisco ICS 7750 supports the following MIBs:
CISCO-C2900-MIB—Supports the SSP card.
CISCO-CCM-MIB—Enables the system to get provisioning and statistical
information about Cisco CallManager, devices associated with
Cisco CallManager (such as Cisco IP phones and gateways), and the
Cisco CallManager configuration.
CISCO-CDP-MIB—Enables Cisco CallManager to advertise itself to other
Cisco devices on the network, allowing discovery of other
Cisco CallManager installations on the network.
CISCO-ICSUDSU-MIB—Supports integrated CSU/DSU interfaces in the
MRP.
CISCO-VOICE-IF-MIB—Supports ISDN and analog interfaces in the MRP.
CISCO-ENTITY-FRU-CONTROL-MIB—Supports field replaceable units
(FRUs), such as cards, power supply modules, and the fan tray.
ENTITY-MIB—Supports the chassis.
MIB II (RFC1213)—Represents Ethernet and other types of addresses.
DS1 MIB (RFC1406)—Represents DS1 interfaces in the MRP.
Understanding Traps
An agent can send traps to the manager that identify important system events. The
following are examples of conditions where an agent might send an SNMP trap
message to an NMS specified as a trap receiver:
An interface or card starts or stops running.
Spanning-tree topology changes are made.
Authentication failures occur.
When an agent detects an alarm condition, it reacts by logging information about
the time, type, and severity of the condition and generates a trap—or notification
message—that is sent to certain IP addresses.
