CTRON-CDP-MIB
AI MIB Summary
The CTRON-CDP-MIB module exposes Cisco Discovery Protocol (CDP) neighbor tables on Ctron network devices, providing per-port Layer 2 adjacency data including device identifiers, port mappings, and platform details to enable automated topology discovery and mapping.
This module defines a schema that maintains per port neighbor information for the express purpose of helping a managment application map Layaer 2 topology.

ctCDPNeighbor OBJECT IDENTIFIER .1.3.6.1.4.1.52.4.1.2.19.1 |
ctCDPNeighborLastChangeThe value of sysUpTime at the time the cdpNeighborTable
was subject to these events: row insertion, row deletionro TimeStamp (SNMPv2-TC) .1.3.6.1.4.1.52.4.1.2.19.1.1 |
ctCDPNeighborLastDeleteThe value of sysUpTime the last time an entry in the
ctCDPNeighborTable was deleted. This should be polled
at an interval no greater than one second.
When it changes, the whole table should be
reread by management with a timeMark of 0 to rebuild
connectivity map.ro TimeStamp (SNMPv2-TC) .1.3.6.1.4.1.52.4.1.2.19.1.2 |

corresponding data for this port may be obtained. In the case
of unnumbered IP Interfaces, this may not be the same as the
port.ro IpAddress .1.3.6.1.4.1.52.4.1.2.19.1.3.1.3 |
ctCDPNeighborPortThe ifIndex of the remote port. Note, there may not be an IP
Interface associated with this port.ro InterfaceIndex (IF-MIB) .1.3.6.1.4.1.52.4.1.2.19.1.3.1.4 |
ctCDPNeighborTypeThe type of entity. This value is used to determine the
general type of the object or service connected to a given port.
In general, it is better to use system group sysServices to
obtain an object's functionality.ro Enumeration .1.3.6.1.4.1.52.4.1.2.19.1.3.1.5 |
ctCDPNeighborChassisMACThe MAC Address of the chassis in architectures
where many manageable elements exist within a
given chassis. If no containing chassis exists,
exists, this value must be set to 000000:000000ro MacAddress (SNMPv2-TC) .1.3.6.1.4.1.52.4.1.2.19.1.3.1.6 |
ctCDPNeighborChassisIPThe IP address of the chassis itself. If no containing chassis
exists, this value must be set to 0.0.0.0ro IpAddress .1.3.6.1.4.1.52.4.1.2.19.1.3.1.7 |
ctCDPNeighborDescriptionA textual description of the neighbor. It
should contain operator diagnostic information
similar to sysDescr: system type, firmware version...ro DisplayString (SNMPv2-TC) .1.3.6.1.4.1.52.4.1.2.19.1.3.1.8 |
ctCDPNeighborPortNameThe value of object ifName of the neighbor's port.ro DisplayString (SNMPv2-TC) .1.3.6.1.4.1.52.4.1.2.19.1.3.1.9 |
ctCDPNeighborCapabilityThe current capabilities of the neighbor port.ro CTCDPCapability .1.3.6.1.4.1.52.4.1.2.19.1.3.1.10 |
ctCDPStatus OBJECT IDENTIFIER .1.3.6.1.4.1.52.4.1.2.19.2 |
ctCDPGlobalStatusThe state of CDP for this entire managed entity. autoEnable(3)
should the default mode for new implementations. In autoEnable
mode, the device listens for CDP messages and upon receipt, begins
sending CDP messages of the same version and type as received.rw Enumeration .1.3.6.1.4.1.52.4.1.2.19.2.1 |
ctCDPAuthenticationCodeThe authentication code may be set to create individual CDP
domains. CDP packets that arrive on a port must contain this
string. This authentication code is global for the entire
managed entity. The default for this string is 16 nulls.rw OCTET STRING .1.3.6.1.4.1.52.4.1.2.19.2.2 |
ctCDPPortTableThis table shows enable/disable CDP status for each port. SEQUENCE OF CtCDPPortTableEntry .1.3.6.1.4.1.52.4.1.2.19.2.3 |
ctCDPPortTableEntryEach entry is indicative of a particuliar port in the system. CtCDPPortTableEntry .1.3.6.1.4.1.52.4.1.2.19.2.3.1 |
ctCDPPortThe ifIndex for a physical port. ifConnectorPresent is true(1)
defines a physical port on which cdp pdus will be emitted.ro InterfaceIndex (IF-MIB) .1.3.6.1.4.1.52.4.1.2.19.2.3.1.1 |
ctCDPPortStatusThe current state administrative of cdp on a physical port.
The ability to enable and disable the sending of CDP pdu's
on a per port basis is controlled here.rw Enumeration .1.3.6.1.4.1.52.4.1.2.19.2.3.1.2 |
ctCDPTransmitFrequencyThe rate in seconds at which CDP pdu's are sent on all enabled ports.rw INTEGER .1.3.6.1.4.1.52.4.1.2.19.2.4 |
ctCDPHoldTimeThe maximum amount of time in seconds to wait before aging out
an entry in the ctCDPNeighborTable. The agent may choose to change
this value based on the hold time it receives from other devices
so as to have a stable neighbor table which ages out entries
in accordance with the transmit frequency.rw INTEGER .1.3.6.1.4.1.52.4.1.2.19.2.5 |
ctCDPVersionThe CDP version supported by this device as a bit string.
For example, given support for two versions of cdp: 3 and 4
the bit representation in big endian form would be: 00001100.ro OCTET STRING .1.3.6.1.4.1.52.4.1.2.19.2.6 |
