lcsEthLinkOAMPortPDURevision – LCOS-SX-MIB

Object

column SNMPv2-TCDisplayString

It indicates the current revision of the Information TLV. 
The value of this field shall start at zero and be incremented each time something in the Information TLV changes. 
Upon reception of an Information TLV from a peer, an OAM client may use this field to decide if it needs to be processed 
(an Information TLV that is identical to the previous Information TLV doesn't need to be parsed as nothing in it has changed).

Syntax

SNMPv2-TCDisplayString

Source: SNMPv2-TCDisplayString
Base type: OctetString
Display format: 255a

Type Description

Represents 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.
