Description: Manages front panel display and LED indicators on Cisco devices, monitoring display text, backlight status, and visual alerts.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCO-ENTITY-DISPLAY-MIB?

CISCO-ENTITY-DISPLAY-MIB is a Cisco Systems, Inc. proprietary MIB reporting the status of physical display devices — LEDs and alphanumeric displays — on Cisco equipment. Its display table, keyed by index, records display type, name, state, color, and displayed text, while a beacon table records whether a display's beacon (locator) mode is enabled. As a hardware-status MIB it lets an administrator confirm what an equipment display currently shows and remotely trigger a locator beacon. It is deployed on Cisco Systems equipment with physical LED/alphanumeric displays. Engineers can download the CISCO-ENTITY-DISPLAY-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-ENTITY-DISPLAY-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Cisco Systems equipment with LED/alphanumeric displays

Monitoring Examples

An administrator enables ceDisplayBeaconEnabled to trigger a locator beacon, helping a technician find a specific unit among a row of racks on Cisco equipment.

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoEntityDisplayMIB	1.3.6.1.4.1.9.9.344			This MIB module provides information about the status of display devices such as Light Emitting Diodes (LEDs) and alphanumeric displays present on the physical entities contained by the managed system.
ciscoEntityDisplayMIBObjects	1.3.6.1.4.1.9.9.344.1
ceDisplayTable	1.3.6.1.4.1.9.9.344.1.1		not-accessible	This table provides information about the display devices on the physical entities in the managed system and their current display status.
ceDisplayEntry	1.3.6.1.4.1.9.9.344.1.1.1		not-accessible	An entry in the ceDisplayTable that provides information about an LED or an alphanumeric display in the system including its current display status.
U32 ceDisplayIndex	1.3.6.1.4.1.9.9.344.1.1.1.1	Unsigned32	not-accessible	An arbitrary index that uniquely identifies an LED or an alphanumeric display on the physical entity identified by entPhysicalIndex.
CDI ceDisplayType	1.3.6.1.4.1.9.9.344.1.1.1.2	CDisplayType	read-only	This object indicates the type of display described in this entry. i.e. whether it is an LED display or an alphanumeric display.
STR ceDisplayName	1.3.6.1.4.1.9.9.344.1.1.1.3	SnmpAdminString	read-only	This object provides a human-readable string which is the name for the display device specified in this entry.
CDI ceDisplayState	1.3.6.1.4.1.9.9.344.1.1.1.4	CDisplayState	read-only	This object indicates the current display state for the display specified in this entry.
CDI ceDisplayColor	1.3.6.1.4.1.9.9.344.1.1.1.5	CDisplayColor	read-only	This object indicates the color currently seen on the display specified in this entry. If the display specified by this entry is an alphanumeric display, i.e. ceDisplayType is of type 'alphanumeric' then, color may not apply and the agent may choose to indicate this by setting this object to 'unknown'.
STR ceDisplayText	1.3.6.1.4.1.9.9.344.1.1.1.6	SnmpAdminString	read-only	This object provides a human-readable string which is the text currently displayed in the alphanumeric display specified in this entry. If the display specified by this entry is an LED, i.e. ceDisplayType is of type 'led' then, this object would be an empty string.
ceDisplayBeaconTable	1.3.6.1.4.1.9.9.344.1.2		not-accessible	This table provides functionality to manage beacon display devices in the managed system.
ceDisplayBeaconEntry	1.3.6.1.4.1.9.9.344.1.2.1		not-accessible	An entry containing management information of beacon functionality of a particular beacon display device. Only those display devices, as specified by entPhysicalIndex in ENTITY-MIB, that support beacon functionality will be populated in this table.
T/F ceDisplayBeaconEnabled	1.3.6.1.4.1.9.9.344.1.2.1.1	TruthValue	read-write	This object specifies if the beacon functionality is administratively enabled for this display device. 'true' - beacon functionality is administratively enabled 'false' - beacon functionality is administratively disabled.
ceDisplayMIBConformance	1.3.6.1.4.1.9.9.344.2
ceDisplayMIBCompliances	1.3.6.1.4.1.9.9.344.2.1
ceDisplayMIBCompliance	1.3.6.1.4.1.9.9.344.2.1.1			The compliance statement for entities that implement the CISCO-ENTITY-DISPLAY-MIB. This compliance statement is deprecated and superceded by ceDisplayMIBCompliance2.
ceDisplayMIBCompliance2	1.3.6.1.4.1.9.9.344.2.1.2			The compliance statement for entities that implement the CISCO-ENTITY-DISPLAY-MIB.
ceDisplayMIBGroups	1.3.6.1.4.1.9.9.344.2.2
ceDisplayGroup	1.3.6.1.4.1.9.9.344.2.2.1			A collection of managed objects that provide information about a display in the system including its current state.
ceDisplayLEDGroup	1.3.6.1.4.1.9.9.344.2.2.2			A collection of objects relevant to LED display.
ceDisplayAlphaNumericGroup	1.3.6.1.4.1.9.9.344.2.2.3			A collection of objects relevant to alphanumeric display.
ceDisplayBeaconGroup	1.3.6.1.4.1.9.9.344.2.2.4			A collection of objects relevant to beacon functionality.
