ctron-cdp-mib.mib object
Introduction
Most network devices and programs ship with so-called MIB files to describe the parameters and meanings (i.e.: friendly names) which are available for monitoring via SNMP.
ActiveXperts Network Monitor 2025 can import vendor-specific MIB files, so it can be used to monitor specific OID's (Object Identifiers).
This way, you can monitor your devices, computers, etc. by selecting your relevant OID's by name.
ActiveXperts Network Monitor 2025 can import MIB file ctron-cdp-mib and use it to monitor vendor specific OID's.

Object view of ctron-cdp-mib:
| Scalar Object |
| ctCDPNeighborLastChange |
.1.3.6.1.4.1.52.4.1.2.19.1.1 |
|
The value of sysUpTime at the time the cdpNeighborTable
was subject to these events: row insertion, row deletion
|
| ctCDPNeighborLastDelete |
.1.3.6.1.4.1.52.4.1.2.19.1.2 |
|
The 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.
|
| ctCDPNeighborEntry |
.1.3.6.1.4.1.52.4.1.2.19.1.3.1 |
|
An entry containing objects pertaining to
neighbor devices speaking CDP protocols.
|
| ctCDPGlobalStatus |
.1.3.6.1.4.1.52.4.1.2.19.2.1 |
|
The 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.
|
| ctCDPAuthenticationCode |
.1.3.6.1.4.1.52.4.1.2.19.2.2 |
|
The 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.
|
| ctCDPPortTableEntry |
.1.3.6.1.4.1.52.4.1.2.19.2.3.1 |

| ctCDPTransmitFrequency |
.1.3.6.1.4.1.52.4.1.2.19.2.4 |
|

|
| ctCDPHoldTime |
.1.3.6.1.4.1.52.4.1.2.19.2.5 |
|
The 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.
|
| ctCDPVersion |
.1.3.6.1.4.1.52.4.1.2.19.2.6 |
|
The 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.
|
| ctCDPInPackets |

|
Count of CDP packets successfully transmitted by the
device over all the ports.
|
| ctCDPInvalidVersionPackets |
.1.3.6.1.4.1.52.4.1.2.19.4.3 |
|
Count of CDP packets received with version not
supported by the device.

Count of CDP packets received and could not be parsed
successfully by the device.
|
| ctCDPTransmitErrors |
.1.3.6.1.4.1.52.4.1.2.19.4.5 |

.1.3.6.1.4.1.52.4.1.2.19.4.6 |
|
Count of memory errors occured in the device while
either trying to process the CDP packet or adding the
neighbor entry or while trying to send a CDP packet.
