CTRON-CDP-MIB.mib object view, vendor Enterasys-Networks-Inc

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 2024 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 2024 can import MIB file CTRON-CDP-MIB and use it to monitor vendor specific OID's.

CTRON-CDP-MIB file content

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
Each entry is indicative of a particuliar port in the system.
ctCDPTransmitFrequency	.1.3.6.1.4.1.52.4.1.2.19.2.4
The rate in seconds at which CDP pdu's are sent on all enabled ports.
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	.1.3.6.1.4.1.52.4.1.2.19.4.1
Count of CDP packets received by the device over all the ports.
ctCDPOutPackets	.1.3.6.1.4.1.52.4.1.2.19.4.2
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.
ctCDPParseErrorPackets	.1.3.6.1.4.1.52.4.1.2.19.4.4
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
Count of errors occured by the device while trying to transmit CDP packets.
ctCDPMemoryErrors	.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.
Tabular Object
ctCDPNeighborTimeMark	.1.3.6.1.4.1.52.4.1.2.19.1.3.1.1
A TimeFilter for this entry as defined in RFC 2021.
ctCDPNeighborMAC	.1.3.6.1.4.1.52.4.1.2.19.1.3.1.2
The interface mac address of neighboring entity.
ctCDPNeighborIP	.1.3.6.1.4.1.52.4.1.2.19.1.3.1.3
The IP address of SNMP agent on neighboring entity from which corresponding data for this port may be obtained. In the case of unnumbered IP Interfaces, this may not be the same as the port.
ctCDPNeighborPort	.1.3.6.1.4.1.52.4.1.2.19.1.3.1.4
The ifIndex of the remote port. Note, there may not be an IP Interface associated with this port.
ctCDPNeighborType	.1.3.6.1.4.1.52.4.1.2.19.1.3.1.5
The 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.
