Integer32 (0..2147483647)

The ifIndex value of the local interface. For 802.3 Repeaters on which the repeater ports do not have ifIndex values assigned, this value is a unique value for the port, and greater than any ifIndex value supported by the repeater; in this case, the specific port is indicated by corresponding values of cdpInterfaceGroup and cdpInterfacePort, where these values correspond to the group number and port number values of RFC 1516.

TruthValue1 = true2 = falseRepresents a boolean value. · Integer32

An indication of whether the Cisco Discovery Protocol is currently running on this interface. This variable has no effect when CDP is disabled (cdpGlobalRun = FALSE).

INTEGER (5..254) · Integer32 · seconds

The interval at which CDP messages are to be generated on this interface. The default value is 60 seconds.

Integer32

This object is only relevant to interfaces which are repeater ports on 802.3 repeaters. In this situation, it indicates the RFC1516 group number of the repeater port which corresponds to this interface.

DisplayStringRepresents textual information taken from the NVT ASCII character set, as defined in pages 4, 10-11 of RFC 854. To summarize RFC 854, the NVT ASCII repertoire specifies: - the use of character codes 0-127 (decimal) - the graphics characters (32-126) are interpreted as US ASCII - NUL, LF, CR, BEL, BS, HT, VT and FF have the special meanings specified in RFC 854 - the other 25 codes have no standard interpretation - the sequence 'CR LF' means newline - the sequence 'CR NUL' means carriage-return - an 'LF' not preceded by a 'CR' means moving to the same column on the next line. - the sequence 'CR x' for any x other than LF or NUL is illegal. (Note that this also means that a string may end with either 'CR LF' or 'CR NUL', but not with CR.) Any object defined using this syntax may not exceed 255 characters in length. SIZE (0..255) · OCTET STRING · hint 255a

The name of the local interface as advertised by CDP in the Port-ID TLV

INTEGER1 = trusted2 = noTrust · Integer32

Indicates the value to be sent by Extended Trust TLV. If trusted(1) is configured, the value of Extended Trust TLV is one byte in length with its least significant bit equal to 1 to indicate extended trust. All other bits are 0. If noTrust(2) is configured, the value of Extended Trust TLV is one byte in length with its least significant bit equal to 0 to indicate no extended trust. All other bits are 0.

Unsigned32 (0..7)

Indicates the value to be sent by COS for Untrusted Ports TLV.

Integer32 (0..2147483647)

Normally, the ifIndex value of the local interface. For 802.3 Repeaters for which the repeater ports do not have ifIndex values assigned, this value is a unique value for the port, and greater than any ifIndex value supported by the repeater; the specific port number in this case, is given by the corresponding value of cdpInterfacePort.

Integer32 (0..2147483647)

A unique value for each device from which CDP messages are being received.

The (first) network-layer address of the device as reported in the Address TLV of the most recently received CDP message. For example, if the corresponding instance of cacheAddressType had the value 'ip(1)', then this object would be an IPv4-address. If the neighbor device is SNMP-manageable, it is supposed to generate its CDP messages such that this address is one at which it will receive SNMP messages. Use cdpCtAddressTable to extract the remaining addresses from the Address TLV received most recently.

Indicates the physical location, as reported by the most recent CDP message, of a connector which is on, or physically connected to, the remote device's interface over which the CDP packet is sent. This object is not instantiated if no Physical Location field (TLV) was reported by the most recently received CDP message.

TimeStampThe value of the sysUpTime object at which a specific occurrence happened. The specific occurrence must be defined in the description of any object defined using this type. If sysUpTime is reset to zero as a result of a re- initialization of the network management (sub)system, then the values of all TimeStamp objects are also reset. However, after approximately 497 days without a re- initialization, the sysUpTime object will reach 2^^32-1 and then increment around to zero; in this case, existing values of TimeStamp objects do not change. This can lead to ambiguities in the value of TimeStamp objects. · TimeTicks
